+<p>The RegEx module presents Regular Expression string manipulation to BlitzMax applications.<br>
+RegEx uses the open-source <a href="http://www.pcre.org">PCRE</a> library by Philip Hazel.</p>
+<h2>Using RegEx in your Apps</h2>
+<p>
+Performing regular expression search and replace with the RegEx module is simple. First, create a <a href="#TRegEx">TRegEx</a> type, and then either perform a <a href="#Find">Find</a> or <a href="#Replace">Replace</a>/<a href="#ReplaceAll">ReplaceAll</a> on it.
+</p>
+<p>The <a href="#TRegEx">TRegEx</a> <a href="#Create">Create</a> function has two parameters.<br>
+The first, <b>searchPattern</b> is the actual regular expression you will be using to perform your searches.<br>
+The second parameter, <b>options</b>, allows you to change the current global <a href="#TRegExOptions">TRegExOptions</a> object for the
+regular expression engine.
+</p>
+<h3>Finding</h3>
+<p>To perform a search, you use the <a href="#Find">Find</a> method. This method takes a <b>target</b> parameter, which is the text that you wish to search. You can also optionally provide a <b>startPos</b> value, indicating where in <b>target</b> you want to start the search.</p>
+<p>To make searching easier, <a href="#Find">Find</a> can also be used without any parameters. In this case it will search the original <b>target</b> string from the end of the last match. This way you can step through the entire string find all the matches.
+</p>
+<p>On a successful match, <a href="#Find">Find</a> returns a <a href="#TRegExMatch">TRegExMatch</a> object. Otherwise, it returns Null.</p>
+<p><a href="#TRegExMatch">TRegExMatch</a> contains information of the matched text, including its position in <b>target</b>. It can also hold details of all subpattern groups that the regular expression matches. (Described in detail below).
+</p>
+<h3>Replacing</h3>
+<p>The two "replace" methods can use the regular expression search to replace matches with other text. They take three parameters. The <b>target</b> string which has text that you want to perform the replace on. The replacement text, <b>replaceWith</b>, and the optional <b>startPos</b> which indicates where the search/replace should begin.<br>
+They return a new string which has the replacements applied to it.</p>
+<p><a href="#Replace">Replace</a> will act on the first match it finds. Since this method
+doesn't change <b>target</b> directly, calling this again (for example, by changing the startPos) on the same string will not show previous replaces.<br>
+<a href="#ReplaceAll">ReplaceAll</a> will replace all matches from <b>startPos</b> until the end of the string.</p>

+<h3>Characters and Metacharacters</h3>
+<p>A regular expression is a pattern that is matched against a subject string from left to right. Most characters stand for themselves in a pattern, and match the corresponding characters in the subject. As a trivial example, the pattern
+<pre>  The quick brown fox</pre>
+matches a portion of a subject string that is identical to itself. When caseless matching is specified (see <a href="#caseSensitive">caseSensitive</a> option), letters are matched independently of case. 
+</p>
+<p>
+The power of regular expressions comes from the ability to include alternatives and repetitions in the pattern. These are encoded in the pattern by the use of <i>metacharacters</i>, which do not stand for themselves but instead are interpreted in some special way.
+</p>
+<p>
+There are two different sets of metacharacters:
+<ul>
+<li>those that are recognized anywhere in the pattern <b>except</b> within square brackets.</li>
+<li>those that are recognized <b>within</b> square brackets.</li>
+</ul>
+Outside square brackets, the metacharacters are as follows:
+</p>
+<table width="90%" align="center">
+<tr><td>  \   </td><td>general escape character with several uses</td></tr>
+<tr><td>  ^   </td><td>assert start of string (or line, in multiline mode. See <a href="#targetIsMultiline">targetIsMultiline</a>)</td></tr>
+<tr><td>  $   </td><td>assert end of string (or line, in multiline mode. See <a href="#targetIsMultiline">targetIsMultiline</a>)</td></tr>
+<tr><td>  .   </td><td>match any character except newline (by default)</td></tr>
+<tr><td>  [   </td><td>start character class definition</td></tr>
+<tr><td>  |   </td><td>start of alternative branch</td></tr>
+<tr><td>  (   </td><td>start subpattern</td></tr>
+<tr><td>  )   </td><td>end subpattern</td></tr>
+<tr><td>  ?   </td><td>extends the meaning of (<br>
+             also 0 or 1 quantifier<br>
+             also quantifier minimizer</td></tr>
+<tr><td>  *   </td><td>0 or more quantifier</td></tr>
+<tr><td>  +   </td><td>1 or more quantifier<br>
+             also "possessive quantifier"</td></tr>
+<tr><td>  {   </td><td>start min/max quantifier</td></tr>
+</table>
+<p>
+Part of a pattern that is in square brackets is called a "character class". In a character class the only metacharacters are:</p>
+<table width="90%" align="center">
+<tr><td>  \   </td><td>general escape character</td></tr>
+<tr><td>  ^   </td><td>negate the class, but only if the first character</td></tr>
+<tr><td>  -   </td><td>indicates character range</td></tr>
+<tr><td>  [   </td><td>POSIX character class (only if followed by POSIX syntax)</td></tr>
+<tr><td>  ]   </td><td>terminates the character class</td></tr>
+</table>
+The following sections describe the use of each of the metacharacters.
+<a name="Backslash"></a>
+<h3>Backslash</h3>
+<p>
+The backslash character has several uses. Firstly, if it is followed by a non-alphanumeric character, it takes away any special meaning that character may have. This use of backslash as an escape character applies both inside and outside character classes.
+</p>
+<p>
+For example, if you want to match a * character, you write \* in the pattern. This escaping action applies whether or not the following character would otherwise be interpreted as a metacharacter, so it is always safe to precede a non-alphanumeric with backslash to specify that it stands for itself. In particular, if you want to match a backslash, you write \\.
+</p>
+<p>
+If you want to remove the special meaning from a sequence of characters, you can do so by putting them between \Q and \E. This is different from Perl in that $ and @ are handled as literals in \Q...\E sequences in RegEx, whereas in Perl, $ and @ cause variable interpolation. Note the following examples:
+</p>
+<table width="90%" align="center">
+<tr><th>Pattern</th><th>RegEx matches</th><th>Perl matches</th></tr>
+<tr><td>\Qabc$xyz\E</td><td>abc$xyz</td><td>abc followed by the contents of $xyz</td></tr>
+<tr><td>\Qabc\$xyz\E</td><td>abc\$xyz</td><td>abc\$xyz</td></tr>
+<tr><td>\Qabc\E\$\Qxyz\E</td><td>abc$xyz</td><td>abc$xyz</td></tr>
+</table>
+The \Q...\E sequence is recognized both inside and outside character classes.
+<a name="NonprintingCharacters"></a>
+<h3>Non-printing Characters</h3>
+<p>
+A second use of backslash provides a way of encoding non-printing characters in patterns in a visible manner. There is no restriction on the appearance of non-printing characters, apart from the binary zero that terminates a pattern, but when a pattern is being prepared by text editing, it is usually easier to use one of the following escape sequences than the binary character it represents:
+</p>
+<table width="90%" align="center">
+<tr><td>  \a       </td><td> alarm, that is, the BEL character (hex 07)</td></tr>
+<tr><td>  \cx      </td><td> "control-x", where x is any character</td></tr>
+<tr><td>  \e       </td><td> escape (hex 1B)</td></tr>
+<tr><td>  \f       </td><td> formfeed (hex 0C)</td></tr>
+<tr><td>  \n       </td><td> newline (hex 0A)</td></tr>
+<tr><td>  \r       </td><td> carriage return (hex 0D)</td></tr>
+<tr><td>  \t       </td><td> tab (hex 09)</td></tr>
+<tr><td>  \ddd     </td><td> character with octal code ddd, or backreference</td></tr>
+<tr><td>  \xhh     </td><td> character with hex code hh</td></tr>
+<tr><td>  \x{hhh..}</td><td> character with hex code hhh..</td></tr>
+</table>
+<p>
+The precise effect of \cx is as follows: if x is a lower case letter, it is converted to upper case. Then bit 6 of the character (hex 40) is inverted. Thus \cz becomes hex 1A, but \c{ becomes hex 3B, while \c; becomes hex 7B.
+<p>
+</p>
+After \x, from zero to two hexadecimal digits are read (letters can be in upper or lower case). Any number of hexadecimal digits may appear between \x{ and }, but the value of the character code must be less than 2**31 (that is, the maximum hexadecimal value is 7FFFFFFF). If characters other than hexadecimal digits appear between \x{ and }, or if there is no terminating }, this form of escape is not recognized. Instead, the initial \x will be interpreted as a basic hexadecimal escape, with no following digits, giving a character whose value is zero.
+</p>
+<p>
+Characters whose value is less than 256 can be defined by either of the two syntaxes for \x. There is no difference in the way they are handled. For example, \xdc is exactly the same as \x{dc}.
+</p>
+<p>
+After \0 up to two further octal digits are read. If there are fewer than two digits, just those that are present are used. Thus the sequence \0\x\07 specifies two binary zeros followed by a BEL character (code value 7). Make sure you supply two digits after the initial zero if the pattern character that follows is itself an octal digit.
+</p>
+<p>The handling of a backslash followed by a digit other than 0 is complicated. Outside a character class, RegEx reads it and any following digits as a decimal number. If the number is less than 10, or if there have been at least that many previous capturing left parentheses in the expression, the entire sequence is taken as a back reference.
+</p>
+<p>
+Inside a character class, or if the decimal number is greater than 9 and there have not been that many capturing subpatterns, RegEx re-reads up to three octal digits following the backslash, and uses them to generate a data character. Any subsequent digits stand for themselves. Values up to \777 are permitted. For example:
+</p>
+<table width="90%" align="center">
+<tr><td>  \040  </td><td>is another way of writing a space</td></tr>
+<tr><td>  \40   </td><td>is the same, provided there are fewer than 40 previous capturing subpatterns</td></tr>
+<tr><td>  \7    </td><td>is always a back reference</td></tr>
+<tr><td>  \11   </td><td>might be a back reference, or another way of writing a tab</td></tr>
+<tr><td>  \011  </td><td>is always a tab</td></tr>
+<tr><td>  \0113 </td><td>is a tab followed by the character "3"</td></tr>
+<tr><td>  \113  </td><td>might be a back reference, otherwise the character with octal code 113</td></tr>
+<tr><td>  \377  </td><td>might be a back reference, otherwise the byte consisting entirely of 1 bits</td></tr>
+<tr><td>  \81   </td><td>is either a back reference, or a binary zero followed by the two characters "8" and "1"</td></tr>
+</table>
+<p>
+Note that octal values of 100 or greater must not be introduced by a leading zero, because no more than three octal digits are ever read.
+</p>
+<p>
+All the sequences that define a single character value can be used both inside and outside character classes. In addition, inside a character class, the sequence \b is interpreted as the backspace character (hex 08), and the sequences \R and \X are interpreted as the characters "R" and "X", respectively. Outside a character class, these sequences have different meanings.
+</p>
+<a name="Genericcharactertypes"></a>
+<h3>Generic character types</h3>
+<p>
+Another use of backslash is for specifying generic character types. The following are always recognized:
+</p>
+<table width="90%" align="center">
+<tr><td>  \d   </td><td>any decimal digit</td></tr>
+<tr><td>  \D   </td><td>any character that is not a decimal digit</td></tr>
+<tr><td>  \s   </td><td>any whitespace character</td></tr>
+<tr><td>  \S   </td><td>any character that is not a whitespace character</td></tr>
+<tr><td>  \w   </td><td>any "word" character</td></tr>
+<tr><td>  \W   </td><td>any "non-word" character</td></tr>
+</table>
+<p>
+Each pair of escape sequences partitions the complete set of characters into two disjoint sets. Any given character matches one, and only one, of each pair.
+</p>
+<p>
+These character type sequences can appear both inside and outside character classes. They each match one character of the appropriate type. If the current matching point is at the end of the subject string, all of them fail, since there is no character to match.
+</p>
+<p>
+For compatibility with Perl, \s does not match the VT character (code 11). This makes it different from the the POSIX "space" class. The \s characters are HT (9), LF (10), FF (12), CR (13), and space (32).
+</p>
+<p>
+A "word" character is an underscore or any character less than 256 that is a letter or digit.<br>
+Characters with values greater than 128 never match \d, \s, or \w, and always match \D, \S, and \W.
+</p>
+<a name="Newlinesequences"></a>
+<h3>Newline sequences</h3>
+<p>
+Outside a character class, the escape sequence \R matches any Unicode newline sequence. This is an extension to Perl. \R is equivalent to the following:
+<pre>  (?&gt;\r\n|\n|\x0b|\f|\r|\x85|\x2028|\x2029)</pre>
+This is an example of an "atomic group", details of which are given below. This particular group matches either the two-character sequence CR followed by LF, or one of the single characters LF (linefeed, U+000A), VT (vertical tab, U+000B), FF (formfeed, U+000C), CR (carriage return, U+000D), NEL (next line, U+0085), LS (line separator, U+2028) or PS (paragraph separator, U+2029). The two-character sequence is treated as a single unit that cannot be split.
+</p>
+<p>
+Inside a character class, \R matches the letter "R".
+</p>
+<a name="Unicodecharacterproperties"></a>
+<h3>Unicode character properties</h3>
+<p>
+Three additional escape sequences to match character properties are available when in conjunction with UTF-8 strings. They are:
+</p>
+<table width="90%" align="center">
+<tr><td>  \p{xx}  </td><td>a character with the xx property</td></tr>
+<tr><td>  \P{xx}  </td><td>a character without the xx property</td></tr>
+<tr><td>  \X      </td><td>an extended Unicode sequence</td></tr>
+</table>
+<p>
+The property names represented by xx above are limited to the Unicode script names, the general category properties, and "Any", which matches any character (including newline). Other properties such as "InMusicalSymbols" are not currently supported by RegEx. Note that \P{Any} does not match any characters, so always causes a match failure.
+</p>
+<p>
+Sets of Unicode characters are defined as belonging to certain scripts. A character from one of these sets can be matched using a script name. For example:
+</p>
+<pre>
+  \p{Greek}
+  \P{Han}
+</pre>
+<p>
+Those that are not part of an identified script are lumped together as "Common". The current list of scripts is:
+</p>
+<p>
+Arabic, Armenian, Balinese, Bengali, Bopomofo, Braille, Buginese, Buhid, Canadian_Aboriginal, Cherokee, Common, Coptic, Cuneiform, Cypriot, Cyrillic, Deseret, Devanagari, Ethiopic, Georgian, Glagolitic, Gothic, Greek, Gujarati, Gurmukhi, Han, Hangul, Hanunoo, Hebrew, Hiragana, Inherited, Kannada, Katakana, Kharoshthi, Khmer, Lao, Latin, Limbu, Linear_B, Malayalam, Mongolian, Myanmar, New_Tai_Lue, Nko, Ogham, Old_Italic, Old_Persian, Oriya, Osmanya, Phags_Pa, Phoenician, Runic, Shavian, Sinhala, Syloti_Nagri, Syriac, Tagalog, Tagbanwa, Tai_Le, Tamil, Telugu, Thaana, Thai, Tibetan, Tifinagh, Ugaritic, Yi.
+</p>
+<p>
+Each character has exactly one general category property, specified by a two-letter abbreviation. For compatibility with Perl, negation can be specified by including a circumflex between the opening brace and the property name. For example, \p{^Lu} is the same as \P{Lu}.
+</p>
+<p>
+If only one letter is specified with \p or \P, it includes all the general category properties that start with that letter. In this case, in the absence of negation, the curly brackets in the escape sequence are optional; these two examples have the same effect:
+</p>
+<pre>
+  \p{L}
+  \pL
+</pre>
+<p>
+The following general category property codes are supported:
+</p>
+<table width="90%" align="center">
+<tr><td>  C     </td><td>Other</td></tr>
+<tr><td>  Cc    </td><td>Control</td></tr>
+<tr><td>  Cf    </td><td>Format</td></tr>
+<tr><td>  Cn    </td><td>Unassigned</td></tr>
+<tr><td>  Co    </td><td>Private use</td></tr>
+<tr><td>  Cs    </td><td>Surrogate</td></tr>
+
+<tr><td>  L     </td><td>Letter</td></tr>
+<tr><td>  Ll    </td><td>Lower case letter</td></tr>
+<tr><td>  Lm    </td><td>Modifier letter</td></tr>
+<tr><td>  Lo    </td><td>Other letter</td></tr>
+<tr><td>  Lt    </td><td>Title case letter</td></tr>
+<tr><td>  Lu    </td><td>Upper case letter</td></tr>
+
+<tr><td>  M     </td><td>Mark</td></tr>
+<tr><td>  Mc    </td><td>Spacing mark</td></tr>
+<tr><td>  Me    </td><td>Enclosing mark</td></tr>
+<tr><td>  Mn    </td><td>Non-spacing mark</td></tr>
+
+<tr><td>  N     </td><td>Number</td></tr>
+<tr><td>  Nd    </td><td>Decimal number</td></tr>
+<tr><td>  Nl    </td><td>Letter number</td></tr>
+<tr><td>  No    </td><td>Other number</td></tr>
+
+<tr><td>  P     </td><td>Punctuation</td></tr>
+<tr><td>  Pc    </td><td>Connector punctuation</td></tr>
+<tr><td>  Pd    </td><td>Dash punctuation</td></tr>
+<tr><td>  Pe    </td><td>Close punctuation</td></tr>
+<tr><td>  Pf    </td><td>Final punctuation</td></tr>
+<tr><td>  Pi    </td><td>Initial punctuation</td></tr>
+<tr><td>  Po    </td><td>Other punctuation</td></tr>
+<tr><td>  Ps    </td><td>Open punctuation</td></tr>
+
+<tr><td>  S     </td><td>Symbol</td></tr>
+<tr><td>  Sc    </td><td>Currency symbol</td></tr>
+<tr><td>  Sk    </td><td>Modifier symbol</td></tr>
+<tr><td>  Sm    </td><td>Mathematical symbol</td></tr>
+<tr><td>  So    </td><td>Other symbol</td></tr>
+
+<tr><td>  Z     </td><td>Separator</td></tr>
+<tr><td>  Zl    </td><td>Line separator</td></tr>
+<tr><td>  Zp    </td><td>Paragraph separator</td></tr>
+<tr><td>  Zs    </td><td>Space separator</td></tr>
+</table>
+<p>
+The special property L&amp; is also supported: it matches a character that has the Lu, Ll, or Lt property, in other words, a letter that is not classified as a modifier or "other".
+</p>
+<p>
+The long synonyms for these properties that Perl supports (such as \p{Letter}) are not supported by RegEx, nor is it permitted to prefix any of these properties with "Is".
+</p>
+<p>
+No character that is in the Unicode table has the Cn (unassigned) property. Instead, this property is assumed for any code point that is not in the Unicode table.
+</p>
+<p>
+Specifying caseless matching does not affect these escape sequences. For example, \p{Lu} always matches only upper case letters.
+</p>
+<p>
+The \X escape matches any number of Unicode characters that form an extended Unicode sequence. \X is equivalent to
+</p>
+<pre>  (?&gt;\PM\pM*)</pre>
+<p>
+That is, it matches a character without the "mark" property, followed by zero or more characters with the "mark" property, and treats the sequence as an atomic group (see below). Characters with the "mark" property are typically accents that affect the preceding character.
+</p>
+<p>
+Matching characters by Unicode property is not fast, because RegEx has to search a structure that contains data for over fifteen thousand characters.
+</p>
+<a name="Simpleassertions"></a>
+<h3>Simple assertions</h3>
+<p>
+The final use of backslash is for certain simple assertions. An assertion specifies a condition that has to be met at a particular point in a match, without consuming any characters from the subject string. The use of subpatterns for more complicated assertions is described below. The backslashed assertions are:
+<p>
+<table width="90%" align="center">
+<tr><td>  \b     </td><td>matches at a word boundary</td></tr>
+<tr><td>  \B     </td><td>matches when not at a word boundary</td></tr>
+<tr><td>  \A     </td><td>matches at the start of the subject</td></tr>
+<tr><td>  \Z     </td><td>matches at the end of the subject<br>
+          also matches before a newline at the end of the subject</td></tr>
+<tr><td>  \z     </td><td>matches only at the end of the subject</td></tr>
+<tr><td>  \G     </td><td>matches at the first matching position in the subject</td></tr>
+</table>
+<p>
+These assertions may not appear in character classes (but note that \b has a different meaning, namely the backspace character, inside a character class).
+</p>
+<p>
+A word boundary is a position in the subject string where the current character and the previous character do not both match \w or \W (i.e. one matches \w and the other matches \W), or the start or end of the string if the first or last character matches \w, respectively.
+</p>
+<p>
+The \A, \Z, and \z assertions differ from the traditional circumflex and dollar (described in the next section) in that they only ever match at the very start and end of the subject string, whatever options are set. Thus, they are independent of <a href="#targetIsMultiline">multiline</a> mode. These three assertions are not affected by the <a href="#stringIsLineBeginning">stringIsLineBeginning (False)</a> or <a href="#stringIsLineEnding">stringIsLineEnding (False)</a> options, which affect only the behaviour of the circumflex and dollar metacharacters. However, if the startPos argument of <a href="#Find">Find</a>/<a href="#Replace">Replace</a> is non-zero, indicating that matching is to start at a point other than the beginning of the subject, \A can never match. The difference between \Z and \z is that \Z matches before a newline at the end of the string as well as at the very end, whereas \z matches only at the end.
+</p>
+<p>
+The \G assertion is true only when the current matching position is at the start point of the match, as specified by the startPos argument of <a href="#Find">Find</a>/<a href="#Replace">Replace</a>. It differs from \A when the value of startPos is non-zero. By calling <a href="#Find">Find</a> multiple times with appropriate arguments, you can mimic Perl's /g option, and it is in this kind of implementation where \G can be useful.
+</p>
+<p>
+Note, however, that RegEx's interpretation of \G, as the start of the current match, is subtly different from Perl's, which defines it as the end of the previous match. In Perl, these can be different when the previously matched string was empty. Because RegEx does just one match at a time, it cannot reproduce this behaviour.
+</p>
+<p>
+If all the alternatives of a pattern begin with \G, the expression is anchored to the starting match position, and the "anchored" flag is set in the compiled regular expression. 
+</p>
+<p>
+<a name="CircumflexandDollar"></a>
+<h3>Circumflex (^) and Dollar ($)</h3>
+<p>
+Outside a character class, in the default matching mode, the circumflex character is an assertion that is true only if the current matching point is at the start of the subject string. If the startPos argument of <a href="#Find">Find</a>/<a href="#Replace">Replace</a> is non-zero, circumflex can never match if the <a href="#targetIsMultiline">targetIsMultiline</a> option is False. Inside a character class, circumflex has an entirely different meaning.
+</p>
+<p>
+Circumflex need not be the first character of the pattern if a number of alternatives are involved, but it should be the first thing in each alternative in which it appears if the pattern is ever to match that branch. If all possible alternatives start with a circumflex, that is, if the pattern is constrained to match only at the start of the subject, it is said to be an "anchored" pattern. (There are also other constructs that can cause a pattern to be anchored.)
+</p>
+<p>
+A dollar character is an assertion that is true only if the current matching point is at the end of the subject string, or immediately before a newline at the end of the string (by default). Dollar need not be the last character of the pattern if a number of alternatives are involved, but it should be the last item in any branch in which it appears. Dollar has no special meaning in a character class.
+</p>
+<p>
+The meaning of dollar can be changed so that it matches only at the very end of the string, by setting the <a href="#dollarEndOnly">dollarEndOnly</a> option at compile time. This does not affect the \Z assertion.
+</p>
+<p>
+The meanings of the circumflex and dollar characters are changed if the <a href="#targetIsMultiline">targetIsMultiline</a> option is True. When this is the case, a circumflex matches immediately after internal newlines as well as at the start of the subject string. It does not match after a newline that ends the string. A dollar matches before any newlines in the string, as well as at the very end, when <a href="#targetIsMultiline">targetIsMultiline</a> is True. When newline is specified as the two-character sequence CRLF, isolated CR and LF characters do not indicate newlines.
+</p>
+<p>
+For example, the pattern /^abc$/ matches the subject string "def\nabc" (where \n represents a newline) in multiline mode, but not otherwise. Consequently, patterns that are anchored in single line mode because all branches start with ^ are not anchored in multiline mode, and a match for circumflex is possible when the startPos argument of <a href="#Find">Find</a>/<a href="#Replace">Replace</a> is non-zero. The <a href="#dollarEndOnly">dollarEndOnly</a> option is ignored if <a href="#targetIsMultiline">targetIsMultiline</a> is True.
+</p>
+<p>
+Note that the sequences \A, \Z, and \z can be used to match the start and end of the subject in both modes, and if all branches of a pattern start with \A it is always anchored, whether or not <a href="#targetIsMultiline">targetIsMultiline</a> is set.
+</p>
+<a name="FullStop"></a>
+<h3>Full Stop (Period, Dot) (.)</h3>
+<p>
+Outside a character class, a dot in the pattern matches any one character in the subject string except (by default) a character that signifies the end of a line. (The matched character may be more than one byte long.)
+</p>
+<p>
+When a line ending is defined as a single character, dot never matches that character; when the two-character sequence CRLF is used, dot does not match CR if it is immediately followed by LF, but otherwise it matches all characters (including isolated CRs and LFs). When any Unicode line endings are being recognized, dot does not match CR or LF or any of the other line ending characters.
+</p>
+<p>
+The behaviour of dot with regard to newlines can be changed. If the <a href="#dotMatchAll">dotMatchAll</a> option is set, a dot matches any one character, without exception. If the two-character sequence CRLF is present in the subject string, it takes two dots to match it.
+</p>
+<p>
+The handling of dot is entirely independent of the handling of circumflex and dollar, the only relationship being that they both involve newlines. Dot has no special meaning in a character class. 
+</p>
+<a name="SquareBracketsandCharacterClasses"></a>
+<h3>Square Brackets and Character Classes</h3>
+<p>
+An opening square bracket introduces a character class, terminated by a closing square bracket. A closing square bracket on its own is not special. If a closing square bracket is required as a member of the class, it should be the first data character in the class (after an initial circumflex, if present) or escaped with a backslash.
+</p>
+A character class matches a single character in the subject. The character may occupy more than one byte (UTF-8). A matched character must be in the set of characters defined by the class, unless the first character in the class definition is a circumflex, in which case the subject character must not be in the set defined by the class. If a circumflex is actually required as a member of the class, ensure it is not the first character, or escape it with a backslash.
+</p>
+<p>
+For example, the character class [aeiou] matches any lower case vowel, while [^aeiou] matches any character that is not a lower case vowel. Note that a circumflex is just a convenient notation for specifying the characters that are in the class by enumerating those that are not. A class that starts with a circumflex is not an assertion: it still consumes a character from the subject string, and therefore it fails if the current pointer is at the end of the string.
+</p>
+<p>
+Characters with values greater than 255 can be included in a class as a literal string of bytes, or by using the \x{ escaping mechanism.
+</p>
+<p>
+When <a href="#caseSensitive">caseless</a> matching is set, any letters in a class represent both their upper case and lower case versions, so for example, a caseless [aeiou] matches "A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a caseful version would.
+</p>
+<p>
+Characters that might indicate line breaks are never treated in any special way when matching character classes, whatever line-ending sequence is in use, and whatever setting of the <a href="#dotMatchAll">dotMatchAll</a> and <a href="#targetIsMultiline">targetIsMultiline</a> options is used. A class such as [^a] always matches one of these characters.
+</p>
+<p>
+The minus (hyphen) character can be used to specify a range of characters in a character class. For example, [d-m] matches any letter between d and m, inclusive. If a minus character is required in a class, it must be escaped with a backslash or appear in a position where it cannot be interpreted as indicating a range, typically as the first or last character in the class.
+</p>
+<p>
+It is not possible to have the literal character "]" as the end character of a range. A pattern such as [W-]46] is interpreted as a class of two characters ("W" and "-") followed by a literal string "46]", so it would match "W46]" or "-46]". However, if the "]" is escaped with a backslash it is interpreted as the end of range, so [W-\]46] is interpreted as a class containing a range followed by two other characters. The octal or hexadecimal representation of "]" can also be used to end a range.
+</p>
+<p>
+Ranges operate in the collating sequence of character values. They can also be used for characters specified numerically, for example [\000-\037]. Ranges can include characters whose values are greater than 255, for example [\x{100}-\x{2ff}].
+</p>
+<p>
+If a range that includes letters is used when <a href="#caseSensitive">caseless</a> matching is set, it matches the letters in either case. For example, [W-c] is equivalent to [][\\^_`wxyzabc], matched caselessly.
+</p>
+<p>
+The character types \d, \D, \p, \P, \s, \S, \w, and \W may also appear in a character class, and add the characters that they match to the class. For example, [\dABCDEF] matches any hexadecimal digit. A circumflex can conveniently be used with the upper case character types to specify a more restricted set of characters than the matching lower case type. For example, the class [^\W_] matches any letter or digit, but not underscore.
+</p>
+<p>
+The only metacharacters that are recognized in character classes are backslash, hyphen (only where it can be interpreted as specifying a range), circumflex (only at the start), opening square bracket (only when it can be interpreted as introducing a POSIX class name - see the next section), and the terminating closing square bracket. However, escaping other non-alphanumeric characters does no harm. 
+</p>
+<a name="POSIXCharacterClasses"></a>
+<h3>POSIX Character Classes</h3>
+<p>
+Perl supports the POSIX notation for character classes. This uses names enclosed by [: and :] within the enclosing square brackets. RegEx also supports this notation. For example,
+</p>
+<pre>  [01[:alpha:]%]</pre>
+<p>
+matches "0", "1", any alphabetic character, or "%". The supported class names are
+</p>
+<table width="90%" align="center">
+<tr><td>  alnum    </td><td>letters and digits</td></tr>
+<tr><td>  alpha    </td><td>letters</td></tr>
+<tr><td>  ascii    </td><td>character codes 0 - 127</td></tr>
+<tr><td>  blank    </td><td>space or tab only</td></tr>
+<tr><td>  cntrl    </td><td>control characters</td></tr>
+<tr><td>  digit    </td><td>decimal digits (same as \d)</td></tr>
+<tr><td>  graph    </td><td>printing characters, excluding space</td></tr>
+<tr><td>  lower    </td><td>lower case letters</td></tr>
+<tr><td>  print    </td><td>printing characters, including space</td></tr>
+<tr><td>  punct    </td><td>printing characters, excluding letters and digits</td></tr>
+<tr><td>  space    </td><td>white space (not quite the same as \s)</td></tr>
+<tr><td>  upper    </td><td>upper case letters</td></tr>
+<tr><td>  word     </td><td>"word" characters (same as \w)</td></tr>
+<tr><td>  xdigit   </td><td>hexadecimal digits</td></tr>
+</table>
+<p>
+The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and space (32). Notice that this list includes the VT character (code 11). This makes "space" different to \s, which does not include VT (for Perl compatibility).
+</p>
+<p>
+The name "word" is a Perl extension, and "blank" is a GNU extension from Perl 5.8. Another Perl extension is negation, which is indicated by a ^ character after the colon. For example,
+</p>
+<pre>  [12[:^digit:]]</pre>
+<p>
+matches "1", "2", or any non-digit. RegEx (and Perl) also recognize the POSIX syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not supported, and an error is given if they are encountered.
+</p>
+<p>
+Characters with values greater than 128 do not match any of the POSIX character classes. 
+</p>
+<a name="VerticalBar"></a>
+<h3>Vertical Bar / Pipe ( | )</h3>
+<p>
+Vertical bar characters are used to separate alternative patterns. For example, the pattern
+</p>
+<pre>  gilbert|sullivan</pre>
+<p>
+matches either "gilbert" or "sullivan". Any number of alternatives may appear, and an empty alternative is permitted (matching the empty string). The matching process tries each alternative in turn, from left to right, and the first one that succeeds is used. If the alternatives are within a subpattern, "succeeds" means matching the rest of the main pattern as well as the alternative in the subpattern.
+</p>
+<a name="InternalOptionSetting"></a>
+<h3>Internal Option Setting</h3>
+<p>
+The settings of the <a href="#caseSensitive">caseSensitive</a>, <a href="#targetIsMultiline">targetIsMultiline</a>, <a href="#dotMatchAll">dotMatchAll</a>, and <a href="#extended">extended</a> options can be changed from within the pattern by a sequence of Perl option letters enclosed between "(?" and ")". The option letters are
+</p>
+<table width="90%" align="center">
+<tr><td>  i  </td><td>for <a href="#caseSensitive">caseSensitive (False)</a></td></tr>
+<tr><td>  m  </td><td>for <a href="#targetIsMultiline">targetIsMultiline</a></td></tr>
+<tr><td>  s  </td><td>for <a href="#dotMatchAll">dotMatchAll</a></td></tr>
+<tr><td>  x  </td><td>for <a href="#extended">extended</a></td></tr>
+</table>
+<p>
+For example, (?im) sets caseless, multiline matching. It is also possible to unset these options by preceding the letter with a hyphen, and a combined setting and unsetting such as (?im-sx), which sets <a href="#targetIsMultiline">targetIsMultiline</a> while unsetting <a href="#caseSensitive">caseSensitive</a>, <a href="#dotMatchAll">dotMatchAll</a> and <a href="#extended">extended</a>, is also permitted. If a letter appears both before and after the hyphen, the option is unset.
+</p>
+<p>
+When an option change occurs at top level (that is, not inside subpattern parentheses), the change applies to the remainder of the pattern that follows. If the change is placed right at the start of a pattern, RegEx extracts it into the global options.
+</p>
+<p>
+An option change within a subpattern (see below for a description of subpatterns) affects only that part of the current pattern that follows it, so
+</p>
+<pre>  (a(?i)b)c</pre>
+<p>
+matches abc and aBc and no other strings (assuming <a href="#caseSensitive">caseSensitive</a> is set). By this means, options can be made to have different settings in different parts of the pattern. Any changes made in one alternative do carry on into subsequent branches within the same subpattern. For example,
+</p>
+<pre>  (a(?i)b|c)</pre>
+<p>
+matches "ab", "aB", "c", and "C", even though when matching "C" the first branch is abandoned before the option setting. This is because the effects of option settings happen at compile time. There would be some very weird behaviour otherwise.
+</p>
+<a name="Subpatterns"></a>
+<h3>Subpatterns</h3>
+<p>
+Subpatterns are delimited by parentheses (round brackets), which can be nested. Turning part of a pattern into a subpattern does two things:
+<p>
+1. It localizes a set of alternatives. For example, the pattern
+</p>
+<pre>  cat(aract|erpillar|)</pre>
+<p>
+matches one of the words "cat", "cataract", or "caterpillar". Without the parentheses, it would match "cataract", "erpillar" or an empty string.
+</p>
+<p>
+2. It sets up the subpattern as a capturing subpattern. This means that, when the whole pattern matches, that portion of the subject string that matched the subpattern is passed back via the returned <a href="#TRegExMatch">TRegExMatch</a> object from the Find method. The methods, <a href="#SubCount">SubCount</a>, <a href="#SubExp">SubExp</a>, <a href="#SubStart">SubStart</a> and <a href="#SubEnd">SubEnd</a> can be used to retrieve the captured subpatterns. Opening parentheses are counted from left to right (starting from 1) to obtain numbers for the capturing subpatterns.
+</p>
+<p>
+For example, if the string "the red king" is matched against the pattern
+</p>
+<pre>  the ((red|white) (king|queen))</pre>
+<p>
+the captured substrings are "red king", "red", and "king", and are numbered 1, 2, and 3, respectively.
+</p>
+<p>
+The fact that plain parentheses fulfil two functions is not always helpful. There are often times when a grouping subpattern is required without a capturing requirement. If an opening parenthesis is followed by a question mark and a colon, the subpattern does not do any capturing, and is not counted when computing the number of any subsequent capturing subpatterns. For example, if the string "the white queen" is matched against the pattern
+</p>
+<pre>  the ((?:red|white) (king|queen))</pre>
+<p>
+the captured substrings are "white queen" and "queen", and are numbered 1 and 2. The maximum number of capturing subpatterns is 65535.
+</p>
+<p>
+As a convenient shorthand, if any option settings are required at the start of a non-capturing subpattern, the option letters may appear between the "?" and the ":". Thus the two patterns
+</p>
+<pre>  (?i:saturday|sunday)
+  (?:(?i)saturday|sunday)</pre>
+<p>
+match exactly the same set of strings. Because alternative branches are tried from left to right, and options are not reset until the end of the subpattern is reached, an option setting in one branch does affect subsequent branches, so the above patterns match "SUNDAY" as well as "Saturday".
+</p>
+<a name="Repetition"></a>
+<h3>Repetition</h3>
+<p>
+Repetition is specified by quantifiers, which can follow any of the following items:
+</p>
+<table width="90%" align="center">
+<tr><td>  a literal data character</td></tr>
+<tr><td>  the dot metacharacter</td></tr>
+<tr><td>  the \C escape sequence</td></tr>
+<tr><td>  the \X escape sequence</td></tr>
+<tr><td>  the \R escape sequence</td></tr>
+<tr><td>  an escape such as \d that matches a single character</td></tr>
+<tr><td>  a character class</td></tr>
+<tr><td>  a back reference (see next section)</td></tr>
+<tr><td>  a parenthesized subpattern (unless it is an assertion)</td></tr>
+</table>
+<p>
+The general repetition quantifier specifies a minimum and maximum number of permitted matches, by giving the two numbers in curly brackets (braces), separated by a comma. The numbers must be less than 65536, and the first must be less than or equal to the second. For example:
+</p>
+<pre>  z{2,4}</pre>
+<p>
+matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special character. If the second number is omitted, but the comma is present, there is no upper limit; if the second number and the comma are both omitted, the quantifier specifies an exact number of required matches. Thus
+</p>
+<pre>  [aeiou]{3,}</pre>
+<p>
+matches at least 3 successive vowels, but may match many more, while
+</p>
+<pre>  \d{8}</pre>
+<p>
+matches exactly 8 digits. An opening curly bracket that appears in a position where a quantifier is not allowed, or one that does not match the syntax of a quantifier, is taken as a literal character. For example, {,6} is not a quantifier, but a literal string of four characters.
+</p>
+<p>
+Quantifiers apply to UTF-8 characters rather than to individual bytes. Thus, for example, \x{100}{2} matches two UTF-8 characters, each of which is represented by a two-byte sequence. Similarly, \X{3} matches three Unicode extended sequences, each of which may be several bytes long (and they may be of different lengths).
+</p>
+<p>
+The quantifier {0} is permitted, causing the expression to behave as if the previous item and the quantifier were not present.
+</p>
+<p>
+For convenience, the three most common quantifiers have single-character abbreviations:
+</p>
+<table width="90%" align="center">
+<tr><td>  *    </td><td>is equivalent to {0,}</td></tr>
+<tr><td>  +    </td><td>is equivalent to {1,}</td></tr>
+<tr><td>  ?    </td><td>is equivalent to {0,1}</td></tr>
+</table>
+<p>
+It is possible to construct infinite loops by following a subpattern that can match no characters with a quantifier that has no upper limit, for example:
+</p>
+<pre>  (a?)*</pre>
+<p>
+If any repetition of the subpattern does in fact match no characters, the loop is forcibly broken.
+</p>
+<p>
+By default, the quantifiers are "greedy", that is, they match as much as possible (up to the maximum number of permitted times), without causing the rest of the pattern to fail. The classic example of where this gives problems is in trying to match comments in C programs. These appear between /* and */ and within the comment, individual * and / characters may appear. An attempt to match C comments by applying the pattern
+</p>
+<pre>  /\*.*\*/</pre>
+<p>
+to the string
+</p>
+<pre>  /* first comment */  not comment  /* second comment */</pre>
+<p>
+fails, because it matches the entire string owing to the greediness of the .* item.
+</p>
+<p>
+However, if a quantifier is followed by a question mark, it ceases to be greedy, and instead matches the minimum number of times possible, so the pattern
+</p>
+<pre>  /\*.*?\*/</pre>
+<p>
+does the right thing with the C comments. The meaning of the various quantifiers is not otherwise changed, just the preferred number of matches. Do not confuse this use of question mark with its use as a quantifier in its own right. Because it has two uses, it can sometimes appear doubled, as in
+</p>
+<pre>  \d??\d</pre>
+<p>
+which matches one digit by preference, but can match two if that is the only way the rest of the pattern matches.
+</p>
+<p>
+If the <a href="#greedy">greedy</a> option is set to False (an option that is not available in Perl), the quantifiers are not greedy by default, but individual ones can be made greedy by following them with a question mark. In other words, it inverts the default behaviour.
+</p>
+<p>
+When a parenthesized subpattern is quantified with a minimum repeat count that is greater than 1 or with a limited maximum, more memory is required for the compiled pattern, in proportion to the size of the minimum or maximum.
+</p>
+<p>
+If a pattern starts with .* or .{0,} and the <a href="#dotMatchAll">dotMatchAll</a> option (equivalent to Perl's /s) is set, thus allowing the dot to match newlines, the pattern is implicitly anchored, because whatever follows will be tried against every character position in the subject string, so there is no point in retrying the overall match at any position after the first. RegEx normally treats such a pattern as though it were preceded by \A.
+</p>
+<p>
+In cases where it is known that the subject string contains no newlines, it is worth setting <a href="#dotMatchAll">dotMatchAll</a> in order to obtain this optimization, or alternatively using ^ to indicate anchoring explicitly.
+</p>
+<p>
+However, there is one situation where the optimization cannot be used. When .* is inside capturing parentheses that are the subject of a backreference elsewhere in the pattern, a match at the start may fail where a later one succeeds. Consider, for example:
+</p>
+<pre>  (.*)abc\1</pre>
+<p>
+If the subject is "xyz123abc123" the match point is the fourth character. For this reason, such a pattern is not implicitly anchored.
+</p>
+<p>
+When a capturing subpattern is repeated, the value captured is the substring that matched the final iteration. For example, after
+</p>
+<pre>  (tweedle[dume]{3}\s*)+</pre>
+<p>
+has matched "tweedledum tweedledee" the value of the captured substring is "tweedledee". However, if there are nested capturing subpatterns, the corresponding captured values may have been set in previous iterations. For example, after
+</p>
+<pre>  /(a|(b))+/</pre>
+<p>
+matches "aba" the value of the second captured substring is "b".
+</p>
+<a name="AtomicGroupingandPossessiveQuantifiers"></a>
+<h3>Atomic Grouping and Possessive Quantifiers</h3>
+<p>
+With both maximizing ("greedy") and minimizing ("ungreedy" or "lazy") repetition, failure of what follows normally causes the repeated item to be re-evaluated to see if a different number of repeats allows the rest of the pattern to match. Sometimes it is useful to prevent this, either to change the nature of the match, or to cause it fail earlier than it otherwise might, when the author of the pattern knows there is no point in carrying on.
+</p>
+<p>
+Consider, for example, the pattern \d+foo when applied to the subject line
+</p>
+<pre>  123456bar</pre>
+<p>
+After matching all 6 digits and then failing to match "foo", the normal action of the matcher is to try again with only 5 digits matching the \d+ item, and then with 4, and so on, before ultimately failing. "Atomic grouping" (a term taken from Jeffrey Friedl's book) provides the means for specifying that once a subpattern has matched, it is not to be re-evaluated in this way.
+</p>
+<p>
+If we use atomic grouping for the previous example, the matcher gives up immediately on failing to match "foo" the first time. The notation is a kind of special parenthesis, starting with (?&gt; as in this example:
+</p>
+<pre>  (?&gt;\d+)foo</pre>
+<p>
+This kind of parenthesis "locks up" the part of the pattern it contains once it has matched, and a failure further into the pattern is prevented from backtracking into it. Backtracking past it to previous items, however, works as normal.
+</p>
+<p>
+An alternative description is that a subpattern of this type matches the string of characters that an identical standalone pattern would match, if anchored at the current point in the subject string.
+</p>
+<p>
+Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as the above example can be thought of as a maximizing repeat that must swallow everything it can. So, while both \d+ and \d+? are prepared to adjust the number of digits they match in order to make the rest of the pattern match, (?&gt;\d+) can only match an entire sequence of digits.
+</p>
+<p>
+Atomic groups in general can of course contain arbitrarily complicated subpatterns, and can be nested. However, when the subpattern for an atomic group is just a single repeated item, as in the example above, a simpler notation, called a "possessive quantifier" can be used. This consists of an additional + character following a quantifier. Using this notation, the previous example can be rewritten as
+</p>
+<p>
+<pre>  \d++foo</pre>
+<p>
+Possessive quantifiers are always greedy; the unsetting of the <a href="#greedy">greedy</a> option is ignored. They are a convenient notation for the simpler forms of atomic group. However, there is no difference in the meaning of a possessive quantifier and the equivalent atomic group, though there may be a performance difference; possessive quantifiers should be slightly faster.
+</p>
+<p>
+RegEx has an optimization that automatically "possessifies" certain simple pattern constructs. For example, the sequence A+B is treated as A++B because there is no point in backtracking into a sequence of A's when B must follow.
+</p>
+When a pattern contains an unlimited repeat inside a subpattern that can itself be repeated an unlimited number of times, the use of an atomic group is the only way to avoid some failing matches taking a very long time indeed. The pattern
+</p>
+<pre>  (\D+|&lt;\d+&gt;)*[!?]</pre>
+<p>
+matches an unlimited number of substrings that either consist of non-digits, or digits enclosed in <>, followed by either ! or ?. When it matches, it runs quickly. However, if it is applied to
+</p>
+<pre>  aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</pre>
+<p>
+it takes a long time before reporting failure. This is because the string can be divided between the internal \D+ repeat and the external * repeat in a large number of ways, and all have to be tried. (The example uses [!?] rather than a single character at the end, because both RegEx and Perl have an optimization that allows for fast failure when a single character is used. They remember the last single character that is required for a match, and fail early if it is not present in the string.) If the pattern is changed so that it uses an atomic group, like this:
+</p>
+<pre>  ((?&gt;\D+)|&lt;\d+&gt;)*[!?]</pre>
+<p>
+sequences of non-digits cannot be broken, and failure happens quickly.
+</p>
+<a name="BackReferences"></a>
+<h3>Back References</h3>
+<p>
+Outside a character class, a backslash followed by a digit greater than 0 (and possibly further digits) is a back reference to a capturing subpattern earlier (that is, to its left) in the pattern, provided there have been that many previous capturing left parentheses.
+</p>
+<p>
+However, if the decimal number following the backslash is less than 10, it is always taken as a back reference, and causes an error only if there are not that many capturing left parentheses in the entire pattern. In other words, the parentheses that are referenced need not be to the left of the reference for numbers less than 10. A "forward back reference" of this type can make sense when a repetition is involved and the subpattern to the right has participated in an earlier iteration.
+</p>
+<p>
+It is not possible to have a numerical "forward back reference" to a subpattern whose number is 10 or more using this syntax because a sequence such as \50 is interpreted as a character defined in octal. See the subsection entitled "Non-printing characters" above for further details of the handling of digits following a backslash. There is no such problem when named parentheses are used. A back reference to any subpattern is possible using named parentheses (see below).
+</p>
+<p>
+Another way of avoiding the ambiguity inherent in the use of digits following a backslash is to use the \g escape sequence. This escape must be followed by a positive or a negative number, optionally enclosed in braces. These examples are all identical:
+</p>
+<pre>  (ring), \1
+  (ring), \g1
+  (ring), \g{1}</pre>
+<p>
+A positive number specifies an absolute reference without the ambiguity that is present in the older syntax. It is also useful when literal digits follow the reference. A negative number is a relative reference. Consider this example:
+</p>
+<pre>  (abc(def)ghi)\g{-1}</pre>
+<p>
+The sequence \g{-1} is a reference to the most recently started capturing subpattern before \g, that is, is it equivalent to \2. Similarly, \g{-2} would be equivalent to \1. The use of relative references can be helpful in long patterns, and also in patterns that are created by joining together fragments that contain references within themselves.
+</p>
+<p>
+A back reference matches whatever actually matched the capturing subpattern in the current subject string, rather than anything matching the subpattern itself (see "Subpatterns as subroutines" below for a way of doing that). So the pattern
+</p>
+<pre>  (sens|respons)e and \1ibility</pre>
+<p>
+matches "sense and sensibility" and "response and responsibility", but not "sense and responsibility". If caseful matching is in force at the time of the back reference, the case of letters is relevant. For example,
+</p>
+<pre>  ((?i)rah)\s+\1</pre>
+<p>
+matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original capturing subpattern is matched caselessly.
+</p>
+<p>
+Back references to named subpatterns use the Perl syntax \k<name> or \k'name' or the Python syntax (?P=name). We could rewrite the above example in either of the following ways:
+</p>
+<pre>  (?<p1>(?i)rah)\s+\k<p1>
+  (?P<p1>(?i)rah)\s+(?P=p1)</pre>
+<p>
+A subpattern that is referenced by name may appear in the pattern before or after the reference.
+</p>
+<p>
+There may be more than one back reference to the same subpattern. If a subpattern has not actually been used in a particular match, any back references to it always fail. For example, the pattern
+</p>
+<pre>  (a|(bc))\2</pre>
+<p>
+always fails if it starts to match "a" rather than "bc". Because there may be many capturing parentheses in a pattern, all digits following the backslash are taken as part of a potential back reference number. If the pattern continues with a digit character, some delimiter must be used to terminate the back reference. If the <a href="#extended">extended</a> option is set, this can be whitespace. Otherwise an empty comment (see "Comments" below) can be used.
+</p>
+<p>
+A back reference that occurs inside the parentheses to which it refers fails when the subpattern is first used, so, for example, (a\1) never matches. However, such references can be useful inside repeated subpatterns. For example, the pattern
+</p>
+<pre>  (a|b\1)+</pre>
+<p>
+matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of the subpattern, the back reference matches the character string corresponding to the previous iteration. In order for this to work, the pattern must be such that the first iteration does not need to match the back reference. This can be done using alternation, as in the example above, or by a quantifier with a minimum of zero.
+</p>
+<a name="Assertions"></a>
+<h3>Assertions</h3>
+<p>
+An assertion is a test on the characters following or preceding the current matching point that does not actually consume any characters. The simple assertions coded as \b, \B, \A, \G, \Z, \z, ^ and $ are described above.
+</p>
+<p>
+More complicated assertions are coded as subpatterns. There are two kinds: those that look ahead of the current position in the subject string, and those that look behind it. An assertion subpattern is matched in the normal way, except that it does not cause the current matching position to be changed.
+</p>
+<p>
+Assertion subpatterns are not capturing subpatterns, and may not be repeated, because it makes no sense to assert the same thing several times. If any kind of assertion contains capturing subpatterns within it, these are counted for the purposes of numbering the capturing subpatterns in the whole pattern. However, substring capturing is carried out only for positive assertions, because it does not make sense for negative assertions.
+</p>
+<a name="Lookahead assertions"></a>
+<h3>Lookahead assertions</h3>
+<p>
+Lookahead assertions start with (?= for positive assertions and (?! for negative assertions. For example,
+</p>
+<pre>  \w+(?=;)</pre>
+<p>
+matches a word followed by a semicolon, but does not include the semicolon in the match, and
+</p>
+<pre>  foo(?!bar)</pre>
+<p>
+matches any occurrence of "foo" that is not followed by "bar". Note that the apparently similar pattern
+</p>
+<pre>  (?!foo)bar</pre>
+<p>
+does not find an occurrence of "bar" that is preceded by something other than "foo"; it finds any occurrence of "bar" whatsoever, because the assertion (?!foo) is always true when the next three characters are "bar". A lookbehind assertion is needed to achieve the other effect.
+</p>
+<p>
+If you want to force a matching failure at some point in a pattern, the most convenient way to do it is with (?!) because an empty string always matches, so an assertion that requires there not to be an empty string must always fail.
+</p>
+<a name="Lookbehindassertions"></a>
+<h3>Lookbehind assertions</h3>
+<p>
+Lookbehind assertions start with (?<= for positive assertions and (?&lt;! for negative assertions. For example,
+</p>
+<pre>  (?&lt;!foo)bar</pre>
+<p>
+does find an occurrence of "bar" that is not preceded by "foo". The contents of a lookbehind assertion are restricted such that all the strings it matches must have a fixed length. However, if there are several top-level alternatives, they do not all have to have the same fixed length. Thus
+</p>
+<pre>  (?&lt;=bullock|donkey)</pre>
+<p>
+is permitted, but
+</p>
+<pre>  (?&lt;!dogs?|cats?)</pre>
+<p>
+causes an error at compile time. Branches that match different length strings are permitted only at the top level of a lookbehind assertion. This is an extension compared with Perl (at least for 5.8), which requires all branches to match the same length of string. An assertion such as
+</p>
+<pre>  (?&lt;=ab(c|de))</pre>
+<p>
+is not permitted, because its single top-level branch can match two different lengths, but it is acceptable if rewritten to use two top-level branches:
+</p>
+<pre>  (?&lt;=abc|abde)</pre>
+<p>
+The implementation of lookbehind assertions is, for each alternative, to temporarily move the current position back by the fixed length and then try to match. If there are insufficient characters before the current position, the assertion fails.
+</p>
+<p>
+RegEx does not allow the \C escape to appear in lookbehind assertions, because it makes it impossible to calculate the length of the lookbehind. The \X and \R escapes, which can match different numbers of bytes, are also not permitted.
+</p>
+<p>
+Possessive quantifiers can be used in conjunction with lookbehind assertions to specify efficient matching at the end of the subject string. Consider a simple pattern such as
+</p>
+<pre>  abcd$</pre>
+<p>
+when applied to a long string that does not match. Because matching proceeds from left to right, RegEx will look for each "a" in the subject and then see if what follows matches the rest of the pattern. If the pattern is specified as
+</p>
+<pre>  ^.*abcd$</pre>
+<p>
+the initial .* matches the entire string at first, but when this fails (because there is no following "a"), it backtracks to match all but the last character, then all but the last two characters, and so on. Once again the search for "a" covers the entire string, from right to left, so we are no better off. However, if the pattern is written as
+</p>
+<pre>  ^.*+(?&lt;=abcd)</pre>
+<p>
+there can be no backtracking for the .*+ item; it can match only the entire string. The subsequent lookbehind assertion does a single test on the last four characters. If it fails, the match fails immediately. For long strings, this approach makes a significant difference to the processing time.
+</p>
+<a name="Usingmultipleassertions"></a>
+<h3>Using multiple assertions</h3>
+<p>
+Several assertions (of any sort) may occur in succession. For example,
+</p>
+<pre>  (?&lt;=\d{3})(?&lt;!999)foo</pre>
+<p>
+matches "foo" preceded by three digits that are not "999". Notice that each of the assertions is applied independently at the same point in the subject string. First there is a check that the previous three characters are all digits, and then there is a check that the same three characters are not "999". This pattern does not match "foo" preceded by six characters, the first of which are digits and the last three of which are not "999". For example, it doesn't match "123abcfoo". A pattern to do that is
+</p>
+<pre>  (?&lt;=\d{3}...)(?&lt;!999)foo</pre>
+<p>
+This time the first assertion looks at the preceding six characters, checking that the first three are digits, and then the second assertion checks that the preceding three characters are not "999".
+</p>
+<p>
+Assertions can be nested in any combination. For example,
+</p>
+<pre>  (?&lt;=(?&lt;!foo)bar)baz</pre>
+<p>
+matches an occurrence of "baz" that is preceded by "bar" which in turn is not preceded by "foo", while
+</p>
+<pre>  (?&lt;=\d{3}(?!999)...)foo</pre>
+<p>
+is another pattern that matches "foo" preceded by three digits and any three characters that are not "999".
+</p>
+<a name="ConditionalSubpatterns"></a>
+<h3>Conditional Subpatterns</h3>
+<p>
+It is possible to cause the matching process to obey a subpattern conditionally or to choose between two alternative subpatterns, depending on the result of an assertion, or whether a previous capturing subpattern matched or not. The two possible forms of conditional subpattern are
+</p>
+<pre>  (?(condition)yes-pattern)
+  (?(condition)yes-pattern|no-pattern)</pre>
+<p>
+If the condition is satisfied, the yes-pattern is used; otherwise the no-pattern (if present) is used. If there are more than two alternatives in the subpattern, a compile-time error occurs.
+</p>
+<p>
+There are four kinds of condition: references to subpatterns, references to recursion, a pseudo-condition called DEFINE, and assertions.
+</p>
+<a name="Checkingforausedsubpatternbynumber"></a>
+<h3>Checking for a used subpattern by number</h3>
+<p>
+If the text between the parentheses consists of a sequence of digits, the condition is true if the capturing subpattern of that number has previously matched.
+</p>Checking for a used subpattern by number
+<p>
+Consider the following pattern, which contains non-significant white space to make it more readable (assume the <a href="#extended">extended</a> option) and to divide it into three parts for ease of discussion:
+</p>
+<pre>  ( \( )?    [^()]+    (?(1) \) )</pre>
+<p>
+The first part matches an optional opening parenthesis, and if that character is present, sets it as the first captured substring. The second part matches one or more characters that are not parentheses. The third part is a conditional subpattern that tests whether the first set of parentheses matched or not. If they did, that is, if subject started with an opening parenthesis, the condition is true, and so the yes-pattern is executed and a closing parenthesis is required. Otherwise, since no-pattern is not present, the subpattern matches nothing. In other words, this pattern matches a sequence of non-parentheses, optionally enclosed in parentheses.
+</p>
+<a name="Checkingforausedsubpatternbyname"></a>
+<h3>Checking for a used subpattern by name</h3>
+<p>
+Perl uses the syntax (?(<name>)...) or (?('name')...) to test for a used subpattern by name. The syntax (?(name)...) is also recognized. However, there is a possible ambiguity with this syntax, because subpattern names may consist entirely of digits. RegEx looks first for a named subpattern; if it cannot find one and the name consists entirely of digits, RegEx looks for a subpattern of that number, which must be greater than zero. Using subpattern names that consist entirely of digits is not recommended.
+</p>
+<p>
+Rewriting the above example to use a named subpattern gives this:
+</p>
+<pre>  (?&lt;OPEN&gt; \( )?    [^()]+    (?(&lt;OPEN&gt;) \) )</pre>
+<a name="Checkingforpatternrecursion"></a>
+<h3>Checking for pattern recursion</h3>
+<p>
+If the condition is the string (R), and there is no subpattern with the name R, the condition is true if a recursive call to the whole pattern or any subpattern has been made. If digits or a name preceded by ampersand follow the letter R, for example:
+</p>
+<pre>  (?(R3)...) or (?(R&amp;name)...)</pre>
+<p>
+the condition is true if the most recent recursion is into the subpattern whose number or name is given. This condition does not check the entire recursion stack.
+</p>
+<p>
+At "top level", all these recursion test conditions are false. Recursive patterns are described below.
+</p>
+<a name="Definingsubpatternsforusebyreferenceonly"></a>
+<h3>Defining subpatterns for use by reference only</h3>
+<p>
+If the condition is the string (DEFINE), and there is no subpattern with the name DEFINE, the condition is always false. In this case, there may be only one alternative in the subpattern. It is always skipped if control reaches this point in the pattern; the idea of DEFINE is that it can be used to define "subroutines" that can be referenced from elsewhere. (The use of "subroutines" is described below.) For example, a pattern to match an IPv4 address could be written like this (ignore whitespace and line breaks):
+</p>
+<pre>  (?(DEFINE) (?<byte> 2[0-4]\d | 25[0-5] | 1\d\d | [1-9]?\d) )
+  \b (?&byte) (\.(?&byte)){3} \b</pre>
+<p>
+The first part of the pattern is a DEFINE group inside which a another group named "byte" is defined. This matches an individual component of an IPv4 address (a number less than 256). When matching takes place, this part of the pattern is skipped because DEFINE acts like a false condition.
+</p>
+<p>
+The rest of the pattern uses references to the named group to match the four dot-separated components of an IPv4 address, insisting on a word boundary at each end.
+</p>
+<a name="Assertionconditions"></a>
+<h3>Assertion conditions</h3>
+<p>
+If the condition is not in any of the above formats, it must be an assertion. This may be a positive or negative lookahead or lookbehind assertion. Consider this pattern, again containing non-significant white space, and with the two alternatives on the second line:
+</p>
+<pre>  (?(?=[^a-z]*[a-z])
+  \d{2}-[a-z]{3}-\d{2}  |  \d{2}-\d{2}-\d{2} )</pre>
+<p>
+The condition is a positive lookahead assertion that matches an optional sequence of non-letters followed by a letter. In other words, it tests for the presence of at least one letter in the subject. If a letter is found, the subject is matched against the first alternative; otherwise it is matched against the second. This pattern matches strings in one of the two forms dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
+</p>
+<a name="Comments"></a>
+<h3>Comments</h3>
+<p>
+The sequence (?# marks the start of a comment that continues up to the next closing parenthesis. Nested parentheses are not permitted. The characters that make up a comment play no part in the pattern matching at all.
+</p>
+<p>
+If the <a href="#extended">extended</a> option is set, an unescaped # character outside a character class introduces a comment that continues to immediately after the next newline in the pattern.
+</p>
+<a name="RecursivePatterns"></a>
+<h3>Recursive Patterns</h3>
+<p>
+Consider the problem of matching a string in parentheses, allowing for unlimited nested parentheses. Without the use of recursion, the best that can be done is to use a pattern that matches up to some fixed depth of nesting. It is not possible to handle an arbitrary nesting depth.
+</p>
+<p>
+A special item that consists of (? followed by a number greater than zero and a closing parenthesis is a recursive call of the subpattern of the given number, provided that it occurs inside that subpattern. (If not, it is a "subroutine" call, which is described in the next section.) The special item (?R) or (?0) is a recursive call of the entire regular expression.
+</p>
+<p>
+In RegEx (like Python, but unlike Perl), a recursive subpattern call is always treated as an atomic group. That is, once it has matched some of the subject string, it is never re-entered, even if it contains untried alternatives and there is a subsequent matching failure.
+</p>
+<p>
+This RegEx pattern solves the nested parentheses problem (assume the <a href="#extended">extended</a> option is set so that white space is ignored):
+</p>
+<pre>  \( ( (?&gt;[^()]+) | (?R) )* \)</pre>
+<p>
+First it matches an opening parenthesis. Then it matches any number of substrings which can either be a sequence of non-parentheses, or a recursive match of the pattern itself (that is, a correctly parenthesized substring). Finally there is a closing parenthesis.
+</p>
+<p>
+If this were part of a larger pattern, you would not want to recurse the entire pattern, so instead you could use this:
+</p>
+<pre>  ( \( ( (?&gt;[^()]+) | (?1) )* \) )</pre>
+<p>
+We have put the pattern into parentheses, and caused the recursion to refer to them instead of the whole pattern. In a larger pattern, keeping track of parenthesis numbers can be tricky. It may be more convenient to use named parentheses instead. The Perl syntax for this is (?&amp;name); PCRE's earlier syntax (?P&gt;name) is also supported. We could rewrite the above example as follows:
+</p>
+<pre>  (?&lt;pn&gt; \( ( (?&gt;[^()]+) | (?&amp;pn) )* \) )</pre>
+<p>
+If there is more than one subpattern with the same name, the earliest one is used. This particular example pattern contains nested unlimited repeats, and so the use of atomic grouping for matching strings of non-parentheses is important when applying the pattern to strings that do not match. For example, when this pattern is applied to
+</p>
+<pre>  (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()</pre>
+<p>
+it yields "no match" quickly. However, if atomic grouping is not used, the match runs for a very long time indeed because there are so many different ways the + and * repeats can carve up the subject, and all have to be tested before failure can be reported.
+</p>
+<p>
+At the end of a match, the values set for any capturing subpatterns are those from the outermost level of the recursion at which the subpattern value is set. If the pattern above is matched against
+</p>
+<pre>  (ab(cd)ef)</pre>
+<p>
+the value for the capturing parentheses is "ef", which is the last value taken on at the top level. If additional parentheses are added, giving
+</p>
+<pre>  \( ( ( (?&gt;[^()]+) | (?R) )* ) \)
+     ^                        ^
+     ^                        ^</pre>
+<p>
+the string they capture is "ab(cd)ef", the contents of the top level parentheses. If there are more than 15 capturing parentheses in a pattern, RegEx has to obtain extra memory to store data during a recursion. If no memory can be obtained, the match fails with the PCRE_ERROR_NOMEMORY error.
+</p>
+<p>
+Do not confuse the (?R) item with the condition (R), which tests for recursion. Consider this pattern, which matches text in angle brackets, allowing for arbitrary nesting. Only digits are allowed in nested brackets (that is, when recursing), whereas any characters are permitted at the outer level.
+</p>
+<pre>  &lt; (?: (?(R) \d++  | [^&lt;&gt;]*+) | (?R)) * &gt;</pre>
+<p>
+In this pattern, (?(R) is the start of a conditional subpattern, with two different alternatives for the recursive and non-recursive cases. The (?R) item is the actual recursive call.
+</p>
+<a href="SubpatternsasSubroutines"></a>
+<h3>Subpatterns as Subroutines</h3>
+<p>
+If the syntax for a recursive subpattern reference (either by number or by name) is used outside the parentheses to which it refers, it operates like a subroutine in a programming language. The "called" subpattern may be defined before or after the reference. An earlier example pointed out that the pattern
+</p>
+<pre>  (sens|respons)e and \1ibility</pre>
+<p>
+matches "sense and sensibility" and "response and responsibility", but not "sense and responsibility". If instead the pattern
+</p>
+<pre>  (sens|respons)e and (?1)ibility</pre>
+<p>
+is used, it does match "sense and responsibility" as well as the other two strings. Another example is given in the discussion of DEFINE above.
+</p>
+<p>
+Like recursive subpatterns, a "subroutine" call is always treated as an atomic group. That is, once it has matched some of the subject string, it is never re-entered, even if it contains untried alternatives and there is a subsequent matching failure.
+</p>
+<p>
+When a subpattern is used as a subroutine, processing options such as case-independence are fixed when the subpattern is defined. They cannot be changed for different calls. For example, consider this pattern:
+</p>
+<pre>  (abc)(?i:(?1))</pre>
+<p>
+It matches "abcabc". It does not match "abcABC" because the change of processing option does not affect the called subpattern.
+</p>

+# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered

+# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
+#            (b) Ensure pcretest and pcregrep link with the local library,
+#                not a previously-installed one.
+#            (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
+#                PCRE_SUPPORT_LIBBZ2.
+# 2008-01-20 Brought up to date to include several new features by Christian
+#            Ehrlicher.
+# 2008-01-22 Sheri added options for backward compatibility of library names
+#            when building with minGW:
+#            if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
+#            be built without "lib" as prefix. (The libraries will be named

+#            built by default with Configure and Make.
+# 2008-01-23 PH removed the automatic build of pcredemo.
+# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
+# 2008-07-03 PH updated for revised UCP property support (change of files)
+# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
+#            CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
+#            is included within another project.
+# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
+#            add options to stop the building of pcregrep and the tests, and
+#            to disable the final configuration report.

+Change Log for PCRE2
+--------------------
+
+
+Version 10.31 12-February-2018
+------------------------------
+
+1. Fix typo (missing ]) in VMS code in pcre2test.c.
+
+2. Replace the replicated code for matching extended Unicode grapheme sequences
+(which got a lot more complicated by change 10.30/49) by a single subroutine
+that is called by both pcre2_match() and pcre2_dfa_match().
+
+3. Add idempotent guard to pcre2_internal.h.
+
+4. Add new pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
+PCRE2_CONFIG_COMPILED_WIDTHS.
+
+5. Cut out \C tests in the JIT regression tests when NEVER_BACKSLASH_C is
+defined (e.g. by --enable-never-backslash-C).
+
+6. Defined public names for all the pcre2_compile() error numbers, and used
+the public names in pcre2_convert.c.
+
+7. Fixed a small memory leak in pcre2test (convert contexts).
+
+8. Added two casts to compile.c and one to match.c to avoid compiler warnings.
+
+9. Added code to pcre2grep when compiled under VMS to set the symbol
+PCRE2GREP_RC to the exit status, because VMS does not distinguish between
+exit(0) and exit(1).
+
+10. Added the -LM (list modifiers) option to pcre2test. Also made -C complain
+about a bad option only if the following argument item does not start with a
+hyphen.
+
+11. pcre2grep was truncating components of file names to 128 characters when
+processing files with the -r option, and also (some very odd code) truncating
+path names to 512 characters. There is now a check on the absolute length of
+full path file names, which may be up to 2047 characters long.
+
+12. When an assertion contained (*ACCEPT) it caused all open capturing groups
+to be closed (as for a non-assertion ACCEPT), which was wrong and could lead to
+misbehaviour for subsequent references to groups that started outside the
+assertion. ACCEPT in an assertion now closes only those groups that were
+started within that assertion. Fixes oss-fuzz issues 3852 and 3891.
+
+13. Multiline matching in pcre2grep was misbehaving if the pattern matched
+within a line, and then matched again at the end of the line and over into
+subsequent lines. Behaviour was different with and without colouring, and
+sometimes context lines were incorrectly printed and/or line endings were lost.
+All these issues should now be fixed.
+
+14. If --line-buffered was specified for pcre2grep when input was from a
+compressed file (.gz or .bz2) a segfault occurred. (Line buffering should be
+ignored for compressed files.)
+
+15. Although pcre2_jit_match checks whether the pattern is compiled
+in a given mode, it was also expected that at least one mode is available.
+This is fixed and pcre2_jit_match returns with PCRE2_ERROR_JIT_BADOPTION
+when the pattern is not optimized by JIT at all.
+
+16. The line number and related variables such as match counts in pcre2grep
+were all int variables, causing overflow when files with more than 2147483647
+lines were processed (assuming 32-bit ints). They have all been changed to
+unsigned long ints.
+
+17. If a backreference with a minimum repeat count of zero was first in a
+pattern, apart from assertions, an incorrect first matching character could be
+recorded. For example, for the pattern /(?=(a))\1?b/, "b" was incorrectly set
+as the first character of a match.
+
+18. Characters in a leading positive assertion are considered for recording a
+first character of a match when the rest of the pattern does not provide one.
+However, a character in a non-assertive group within a leading assertion such
+as in the pattern /(?=(a))\1?b/ caused this process to fail. This was an
+infelicity rather than an outright bug, because it did not affect the result of
+a match, just its speed. (In fact, in this case, the starting 'a' was
+subsequently picked up in the study.)
+
+19. A minor tidy in pcre2_match(): making all PCRE2_ERROR_ returns use "return"
+instead of "RRETURN" saves unwinding the backtracks in these cases (only one
+didn't).
+
+20. Allocate a single callout block on the stack at the start of pcre2_match()
+and set its never-changing fields once only. Do the same for pcre2_dfa_match().
+
+21. Save the extra compile options (set in the compile context) with the
+compiled pattern (they were not previously saved), add PCRE2_INFO_EXTRAOPTIONS
+to retrieve them, and update pcre2test to show them.
+
+22. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
+field callout_flags in callout blocks. The bits are set by pcre2_match(), but
+not by JIT or pcre2_dfa_match(). Their settings are shown in pcre2test callouts
+if the callout_extra subject modifier is set. These bits are provided to help
+with tracking how a backtracking match is proceeding.
+
+23. Updated the pcre2demo.c demonstration program, which was missing the extra
+code for -g that handles the case when \K in an assertion causes the match to
+end at the original start point. Also arranged for it to detect when \K causes
+the end of a match to be before its start.
+
+24. Similar to 23 above, strange things (including loops) could happen in
+pcre2grep when \K was used in an assertion when --colour was used or in
+multiline mode. The "end at original start point" bug is fixed, and if the end
+point is found to be before the start point, they are swapped.
+
+25. When PCRE2_FIRSTLINE without PCRE2_NO_START_OPTIMIZE was used in non-JIT
+matching (both pcre2_match() and pcre2_dfa_match()) and the matched string
+started with the first code unit of a newline sequence, matching failed because
+it was not tried at the newline.
+
+26. Code for giving up a non-partial match after failing to find a starting
+code unit anywhere in the subject was missing when searching for one of a
+number of code units (the bitmap case) in both pcre2_match() and
+pcre2_dfa_match(). This was a missing optimization rather than a bug.
+
+27. Tidied up the ACROSSCHAR macro to be like FORWARDCHAR and BACKCHAR, using a
+pointer argument rather than a code unit value. This should not have affected
+the generated code.
+
+28. The JIT compiler has been updated.
+
+29. Avoid pointer overflow for unset captures in pcre2_substring_list_get().
+This could not actually cause a crash because it was always used in a memcpy()
+call with zero length.
+
+30. Some internal structures have a variable-length ovector[] as their last
+element. Their actual memory is obtained dynamically, giving an ovector of
+appropriate length. However, they are defined in the structure as
+ovector[NUMBER], where NUMBER is large so that array bound checkers don't
+grumble. The value of NUMBER was 10000, but a fuzzer exceeded 5000 capturing
+groups, making the ovector larger than this. The number has been increased to
+131072, which allows for the maximum number of captures (65535) plus the
+overall match. This fixes oss-fuzz issue 5415.
+
+31. Auto-possessification at the end of a capturing group was dependent on what
+follows the group (e.g. /(a+)b/ would auto-possessify the a+) but this caused
+incorrect behaviour when the group was called recursively from elsewhere in the
+pattern where something different might follow. This bug is an unforseen
+consequence of change #1 for 10.30 - the implementation of backtracking into
+recursions. Iterators at the ends of capturing groups are no longer considered
+for auto-possessification if the pattern contains any recursions. Fixes
+Bugzilla #2232.
+
+
+Version 10.30 14-August-2017
+----------------------------
+
+1. The main interpreter, pcre2_match(), has been refactored into a new version
+that does not use recursive function calls (and therefore the stack) for
+remembering backtracking positions. This makes --disable-stack-for-recursion a
+NOOP. The new implementation allows backtracking into recursive group calls in
+patterns, making it more compatible with Perl, and also fixes some other
+hard-to-do issues such as #1887 in Bugzilla. The code is also cleaner because
+the old code had a number of fudges to try to reduce stack usage. It seems to
+run no slower than the old code.
+
+A number of bugs in the refactored code were subsequently fixed during testing
+before release, but after the code was made available in the repository. These
+bugs were never in fully released code, but are noted here for the record.
+
+  (a) If a pattern had fewer capturing parentheses than the ovector supplied in
+      the match data block, a memory error (detectable by ASAN) occurred after
+      a match, because the external block was being set from non-existent
+      internal ovector fields. Fixes oss-fuzz issue 781.
+
+  (b) A pattern with very many capturing parentheses (when the internal frame
+      size was greater than the initial frame vector on the stack) caused a
+      crash. A vector on the heap is now set up at the start of matching if the
+      vector on the stack is not big enough to handle at least 10 frames.
+      Fixes oss-fuzz issue 783.
+
+  (c) Handling of (*VERB)s in recursions was wrong in some cases.
+
+  (d) Captures in negative assertions that were used as conditions were not
+      happening if the assertion matched via (*ACCEPT).
+
+  (e) Mark values were not being passed out of recursions.
+
+  (f) Refactor some code in do_callout() to avoid picky compiler warnings about
+      negative indices. Fixes oss-fuzz issue 1454.
+
+  (g) Similarly refactor the way the variable length ovector is addressed for
+      similar reasons. Fixes oss-fuzz issue 1465.
+
+2. Now that pcre2_match() no longer uses recursive function calls (see above),
+the "match limit recursion" value seems misnamed. It still exists, and limits
+the depth of tree that is searched. To avoid future confusion, it has been
+renamed as "depth limit" in all relevant places (--with-depth-limit,
+(*LIMIT_DEPTH), pcre2_set_depth_limit(), etc) but the old names are still
+available for backwards compatibility.
+
+3. Hardened pcre2test so as to reduce the number of bugs reported by fuzzers:
+
+  (a) Check for malloc failures when getting memory for the ovector (POSIX) or
+      the match data block (non-POSIX).
+
+4. In the 32-bit library in non-UTF mode, an attempt to find a Unicode property
+for a character with a code point greater than 0x10ffff (the Unicode maximum)
+caused a crash.
+
+5. If a lookbehind assertion that contained a back reference to a group
+appearing later in the pattern was compiled with the PCRE2_ANCHORED option,
+undefined actions (often a segmentation fault) could occur, depending on what
+other options were set. An example assertion is (?<!\1(abc)) where the
+reference \1 precedes the group (abc). This fixes oss-fuzz issue 865.
+
+6. Added the PCRE2_INFO_FRAMESIZE item to pcre2_pattern_info() and arranged for
+pcre2test to use it to output the frame size when the "framesize" modifier is
+given.
+
+7. Reworked the recursive pattern matching in the JIT compiler to follow the
+interpreter changes.
+
+8. When the zero_terminate modifier was specified on a pcre2test subject line
+for global matching, unpredictable things could happen. For example, in UTF-8
+mode, the pattern //g,zero_terminate read random memory when matched against an
+empty string with zero_terminate. This was a bug in pcre2test, not the library.
+
+9. Moved some Windows-specific code in pcre2grep (introduced in 10.23/13) out
+of the section that is compiled when Unix-style directory scanning is
+available, and into a new section that is always compiled for Windows.
+
+10. In pcre2test, explicitly close the file after an error during serialization
+or deserialization (the "load" or "save" commands).
+
+11. Fix memory leak in pcre2_serialize_decode() when the input is invalid.
+
+12. Fix potential NULL dereference in pcre2_callout_enumerate() if called with
+a NULL pattern pointer when Unicode support is available.
+
+13. When the 32-bit library was being tested by pcre2test, error messages that
+were longer than 64 code units could cause a buffer overflow. This was a bug in
+pcre2test.
+
+14. The alternative matching function, pcre2_dfa_match() misbehaved if it
+encountered a character class with a possessive repeat, for example [a-f]{3}+.
+
+15. The depth (formerly recursion) limit now applies to DFA matching (as
+of 10.23/36); pcre2test has been upgraded so that \=find_limits works with DFA
+matching to find the minimum value for this limit.
+
+16. Since 10.21, if pcre2_match() was called with a null context, default
+memory allocation functions were used instead of whatever was used when the
+pattern was compiled.
+
+17. Changes to the pcre2test "memory" modifier on a subject line. These apply
+only to pcre2_match():
+
+  (a) Warn if null_context is set on both pattern and subject, because the
+      memory details cannot then be shown.
+
+  (b) Remember (up to a certain number of) memory allocations and their
+      lengths, and list only the lengths, so as to be system-independent.
+      (In practice, the new interpreter never has more than 2 blocks allocated
+      simultaneously.)
+
+18. Make pcre2test detect an error return from pcre2_get_error_message(), give
+a message, and abandon the run (this would have detected #13 above).
+
+19. Implemented PCRE2_ENDANCHORED.
+
+20. Applied Jason Hood's patches (slightly modified) to pcre2grep, to implement
+the --output=text (-O) option and the inbuilt callout echo.
+
+21. Extend auto-anchoring etc. to ignore groups with a zero qualifier and
+single-branch conditions with a false condition (e.g. DEFINE) at the start of a
+branch. For example, /(?(DEFINE)...)^A/ and /(...){0}^B/ are now flagged as
+anchored.
+
+22. Added an explicit limit on the amount of heap used by pcre2_match(), set by
+pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). Upgraded pcre2test to show the
+heap limit along with other pattern information, and to find the minimum when
+the find_limits modifier is set.
+
+23. Write to the last 8 bytes of the pcre2_real_code structure when a compiled
+pattern is set up so as to initialize any padding the compiler might have
+included. This avoids valgrind warnings when a compiled pattern is copied, in
+particular when it is serialized.
+
+24. Remove a redundant line of code left in accidentally a long time ago.
+
+25. Remove a duplication typo in pcre2_tables.c
+
+26. Correct an incorrect cast in pcre2_valid_utf.c
+
+27. Update pcre2test, remove some unused code in pcre2_match(), and upgrade the
+tests to improve coverage.
+
+28. Some fixes/tidies as a result of looking at Coverity Scan output:
+
+    (a) Typo: ">" should be ">=" in opcode check in pcre2_auto_possess.c.
+    (b) Added some casts to avoid "suspicious implicit sign extension".
+    (c) Resource leaks in pcre2test in rare error cases.
+    (d) Avoid warning for never-use case OP_TABLE_LENGTH which is just a fudge
+        for checking at compile time that tables are the right size.
+    (e) Add missing "fall through" comment.
+
+29. Implemented PCRE2_EXTENDED_MORE and related /xx and (?xx) features.
+
+30. Implement (?n: for PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
+
+31. If more than one of "push", "pushcopy", or "pushtablescopy" were set in
+pcre2test, a crash could occur.
+
+32. Make -bigstack in RunTest allocate a 64Mb stack (instead of 16 MB) so that
+all the tests can run with clang's sanitizing options.
+
+33. Implement extra compile options in the compile context and add the first
+one: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES.
+
+34. Implement newline type PCRE2_NEWLINE_NUL.
+
+35. A lookbehind assertion that had a zero-length branch caused undefined
+behaviour when processed by pcre2_dfa_match(). This is oss-fuzz issue 1859.
+
+36. The match limit value now also applies to pcre2_dfa_match() as there are
+patterns that can use up a lot of resources without necessarily recursing very
+deeply. (Compare item 10.23/36.) This should fix oss-fuzz #1761.
+
+37. Implement PCRE2_EXTRA_BAD_ESCAPE_IS_LITERAL.
+
+38. Fix returned offsets from regexec() when REG_STARTEND is used with a
+starting offset greater than zero.
+
+39. Implement REG_PEND (GNU extension) for the POSIX wrapper.
+
+40. Implement the subject_literal modifier in pcre2test, and allow jitstack on
+pattern lines.
+
+41. Implement PCRE2_LITERAL and use it to support REG_NOSPEC.
+
+42. Implement PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD for the benefit
+of pcre2grep.
+
+43. Re-implement pcre2grep's -F, -w, and -x options using PCRE2_LITERAL,
+PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This fixes two bugs:
+
+    (a) The -F option did not work for fixed strings containing \E.
+    (b) The -w option did not work for patterns with multiple branches.
+
+44. Added configuration options for the SELinux compatible execmem allocator in
+JIT.
+
+45. Increased the limit for searching for a "must be present" code unit in
+subjects from 1000 to 2000 for 8-bit searches, since they use memchr() and are
+much faster.
+
+46. Arrange for anchored patterns to record and use "first code unit" data,
+because this can give a fast "no match" without searching for a "required code
+unit". Previously only non-anchored patterns did this.
+
+47. Upgraded the Unicode tables from Unicode 8.0.0 to Unicode 10.0.0.
+
+48. Add the callout_no_where modifier to pcre2test.
+
+49. Update extended grapheme breaking rules to the latest set that are in
+Unicode Standard Annex #29.
+
+50. Added experimental foreign pattern conversion facilities
+(pcre2_pattern_convert() and friends).
+
+51. Change the macro FWRITE, used in pcre2grep, to FWRITE_IGNORE because FWRITE
+is defined in a system header in cygwin. Also modified some of the #ifdefs in
+pcre2grep related to Windows and Cygwin support.
+
+52. Change 3(g) for 10.23 was a bit too zealous. If a hyphen that follows a
+character class is the last character in the class, Perl does not give a
+warning. PCRE2 now also treats this as a literal.
+
+53. Related to 52, though PCRE2 was throwing an error for [[:digit:]-X] it was
+not doing so for [\d-X] (and similar escapes), as is documented.
+
+54. Fixed a MIPS issue in the JIT compiler reported by Joshua Kinard.
+
+55. Fixed a "maybe uninitialized" warning for class_uchardata in \p handling in
+pcre2_compile() which could never actually trigger (code should have been cut
+out when Unicode support is disabled).
+
+
+Version 10.23 14-February-2017
+------------------------------
+
+1. Extended pcre2test with the utf8_input modifier so that it is able to
+generate all possible 16-bit and 32-bit code unit values in non-UTF modes.
+
+2. In any wide-character mode (8-bit UTF or any 16-bit or 32-bit mode), without
+PCRE2_UCP set, a negative character type such as \D in a positive class should
+cause all characters greater than 255 to match, whatever else is in the class.
+There was a bug that caused this not to happen if a Unicode property item was
+added to such a class, for example [\D\P{Nd}] or [\W\pL].
+
+3. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
+checking is now done in the pre-pass that identifies capturing groups. This has
+reduced the amount of duplication and made the code tidier. While doing this,
+some minor bugs and Perl incompatibilities were fixed, including:
+
+  (a) \Q\E in the middle of a quantifier such as A+\Q\E+ is now ignored instead
+      of giving an invalid quantifier error.
+
+  (b) {0} can now be used after a group in a lookbehind assertion; previously
+      this caused an "assertion is not fixed length" error.
+
+  (c) Perl always treats (?(DEFINE) as a "define" group, even if a group with
+      the name "DEFINE" exists. PCRE2 now does likewise.
+
+  (d) A recursion condition test such as (?(R2)...) must now refer to an
+      existing subpattern.
+
+  (e) A conditional recursion test such as (?(R)...) misbehaved if there was a
+      group whose name began with "R".
+
+  (f) When testing zero-terminated patterns under valgrind, the terminating
+      zero is now marked "no access". This catches bugs that would otherwise
+      show up only with non-zero-terminated patterns.
+
+  (g) A hyphen appearing immediately after a POSIX character class (for example
+      /[[:ascii:]-z]/) now generates an error. Perl does accept this as a
+      literal, but gives a warning, so it seems best to fail it in PCRE.
+
+  (h) An empty \Q\E sequence may appear after a callout that precedes an
+      assertion condition (it is, of course, ignored).
+
+One effect of the refactoring is that some error numbers and messages have
+changed, and the pattern offset given for compiling errors is not always the
+right-most character that has been read. In particular, for a variable-length
+lookbehind assertion it now points to the start of the assertion. Another
+change is that when a callout appears before a group, the "length of next
+pattern item" that is passed now just gives the length of the opening
+parenthesis item, not the length of the whole group. A length of zero is now
+given only for a callout at the end of the pattern. Automatic callouts are no
+longer inserted before and after explicit callouts in the pattern.
+
+A number of bugs in the refactored code were subsequently fixed during testing
+before release, but after the code was made available in the repository. Many
+of the bugs were discovered by fuzzing testing. Several of them were related to
+the change from assuming a zero-terminated pattern (which previously had
+required non-zero terminated strings to be copied). These bugs were never in
+fully released code, but are noted here for the record.
+
+  (a) An overall recursion such as (?0) inside a lookbehind assertion was not
+      being diagnosed as an error.
+
+  (b) In utf mode, the length of a *MARK (or other verb) name was being checked
+      in characters instead of code units, which could lead to bad code being
+      compiled, leading to unpredictable behaviour.
+
+  (c) In extended /x mode, characters whose code was greater than 255 caused
+      a lookup outside one of the global tables. A similar bug existed for wide
+      characters in *VERB names.
+
+  (d) The amount of memory needed for a compiled pattern was miscalculated if a
+      lookbehind contained more than one toplevel branch and the first branch
+      was of length zero.
+
+  (e) In UTF-8 or UTF-16 modes with PCRE2_EXTENDED (/x) set and a non-zero-
+      terminated pattern, if a # comment ran on to the end of the pattern, one
+      or more code units past the end were being read.
+
+  (f) An unterminated repeat at the end of a non-zero-terminated pattern (e.g.
+      "{2,2") could cause reading beyond the pattern.
+
+  (g) When reading a callout string, if the end delimiter was at the end of the
+      pattern one further code unit was read.
+
+  (h) An unterminated number after \g' could cause reading beyond the pattern.
+
+  (i) An insufficient memory size was being computed for compiling with
+      PCRE2_AUTO_CALLOUT.
+
+  (j) A conditional group with an assertion condition used more memory than was
+      allowed for it during parsing, so too many of them could therefore
+      overrun a buffer.
+
+  (k) If parsing a pattern exactly filled the buffer, the internal test for
+      overrun did not check when the final META_END item was added.
+
+  (l) If a lookbehind contained a subroutine call, and the called group
+      contained an option setting such as (?s), and the PCRE2_ANCHORED option
+      was set, unpredictable behaviour could occur. The underlying bug was
+      incorrect code and insufficient checking while searching for the end of
+      the called subroutine in the parsed pattern.
+
+  (m) Quantifiers following (*VERB)s were not being diagnosed as errors.
+
+  (n) The use of \Q...\E in a (*VERB) name when PCRE2_ALT_VERBNAMES and
+      PCRE2_AUTO_CALLOUT were both specified caused undetermined behaviour.
+
+  (o) If \Q was preceded by a quantified item, and the following \E was
+      followed by '?' or '+', and there was at least one literal character
+      between them, an internal error "unexpected repeat" occurred (example:
+      /.+\QX\E+/).
+
+  (p) A buffer overflow could occur while sorting the names in the group name
+      list (depending on the order in which the names were seen).
+
+  (q) A conditional group that started with a callout was not doing the right
+      check for a following assertion, leading to compiling bad code. Example:
+      /(?(C'XX))?!XX/
+
+  (r) If a character whose code point was greater than 0xffff appeared within
+      a lookbehind that was within another lookbehind, the calculation of the
+      lookbehind length went wrong and could provoke an internal error.
+
+  (t) The sequence \E- or \Q\E- after a POSIX class in a character class caused
+      an internal error. Now the hyphen is treated as a literal.
+
+4. Back references are now permitted in lookbehind assertions when there are
+no duplicated group numbers (that is, (?| has not been used), and, if the
+reference is by name, there is only one group of that name. The referenced
+group must, of course be of fixed length.
+
+5. pcre2test has been upgraded so that, when run under valgrind with valgrind
+support enabled, reading past the end of the pattern is detected, both when
+compiling and during callout processing.
+
+6. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
+reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
+not recognize this syntax.
+
+7. Automatic callouts are no longer generated before and after callouts in the
+pattern.
+
+8. When pcre2test was outputing information from a callout, the caret indicator
+for the current position in the subject line was incorrect if it was after an
+escape sequence for a character whose code point was greater than \x{ff}.
+
+9. Change 19 for 10.22 had a typo (PCRE_STATIC_RUNTIME should be
+PCRE2_STATIC_RUNTIME). Fix from David Gaussmann.
+
+10. Added --max-buffer-size to pcre2grep, to allow for automatic buffer
+expansion when long lines are encountered. Original patch by Dmitry
+Cherniachenko.
+
+11. If pcre2grep was compiled with JIT support, but the library was compiled
+without it (something that neither ./configure nor CMake allow, but it can be
+done by editing config.h), pcre2grep was giving a JIT error. Now it detects
+this situation and does not try to use JIT.
+
+12. Added some "const" qualifiers to variables in pcre2grep.
+
+13. Added Dmitry Cherniachenko's patch for colouring output in Windows
+(untested by me). Also, look for GREP_COLOUR or GREP_COLOR if the environment
+variables PCRE2GREP_COLOUR and PCRE2GREP_COLOR are not found.
+
+14. Add the -t (grand total) option to pcre2grep.
+
+15. A number of bugs have been mended relating to match start-up optimizations
+when the first thing in a pattern is a positive lookahead. These all applied
+only when PCRE2_NO_START_OPTIMIZE was *not* set:
+
+    (a) A pattern such as (?=.*X)X$ was incorrectly optimized as if it needed
+        both an initial 'X' and a following 'X'.
+    (b) Some patterns starting with an assertion that started with .* were
+        incorrectly optimized as having to match at the start of the subject or
+        after a newline. There are cases where this is not true, for example,
+        (?=.*[A-Z])(?=.{8,16})(?!.*[\s]) matches after the start in lines that
+        start with spaces. Starting .* in an assertion is no longer taken as an
+        indication of matching at the start (or after a newline).
+
+16. The "offset" modifier in pcre2test was not being ignored (as documented)
+when the POSIX API was in use.
+
+17. Added --enable-fuzz-support to "configure", causing an non-installed
+library containing a test function that can be called by fuzzers to be
+compiled. A non-installed  binary to run the test function locally, called
+pcre2fuzzcheck is also compiled.
+
+18. A pattern with PCRE2_DOTALL (/s) set but not PCRE2_NO_DOTSTAR_ANCHOR, and
+which started with .* inside a positive lookahead was incorrectly being
+compiled as implicitly anchored.
+
+19. Removed all instances of "register" declarations, as they are considered
+obsolete these days and in any case had become very haphazard.
+
+20. Add strerror() to pcre2test for failed file opening.
+
+21. Make pcre2test -C list valgrind support when it is enabled.
+
+22. Add the use_length modifier to pcre2test.
+
+23. Fix an off-by-one bug in pcre2test for the list of names for 'get' and
+'copy' modifiers.
+
+24. Add PCRE2_CALL_CONVENTION into the prototype declarations in pcre2.h as it
+is apparently needed there as well as in the function definitions. (Why did
+nobody ask for this in PCRE1?)
+
+25. Change the _PCRE2_H and _PCRE2_UCP_H guard macros in the header files to
+PCRE2_H_IDEMPOTENT_GUARD and PCRE2_UCP_H_IDEMPOTENT_GUARD to be more standard
+compliant and unique.
+
+26. pcre2-config --libs-posix was listing -lpcre2posix instead of
+-lpcre2-posix. Also, the CMake build process was building the library with the
+wrong name.
+
+27. In pcre2test, give some offset information for errors in hex patterns.
+This uses the C99 formatting sequence %td, except for MSVC which doesn't
+support it - %lu is used instead.
+
+28. Implemented pcre2_code_copy_with_tables(), and added pushtablescopy to
+pcre2test for testing it.
+
+29. Fix small memory leak in pcre2test.
+
+30. Fix out-of-bounds read for partial matching of /./ against an empty string
+when the newline type is CRLF.
+
+31. Fix a bug in pcre2test that caused a crash when a locale was set either in
+the current pattern or a previous one and a wide character was matched.
+
+32. The appearance of \p, \P, or \X in a substitution string when
+PCRE2_SUBSTITUTE_EXTENDED was set caused a segmentation fault (NULL
+dereference).
+
+33. If the starting offset was specified as greater than the subject length in
+a call to pcre2_substitute() an out-of-bounds memory reference could occur.
+
+34. When PCRE2 was compiled to use the heap instead of the stack for recursive
+calls to match(), a repeated minimizing caseless back reference, or a
+maximizing one where the two cases had different numbers of code units,
+followed by a caseful back reference, could lose the caselessness of the first
+repeated back reference (example: /(Z)(a)\2{1,2}?(?-i)\1X/i should match ZaAAZX
+but didn't).
+
+35. When a pattern is too complicated, PCRE2 gives up trying to find a minimum
+matching length and just records zero. Typically this happens when there are
+too many nested or recursive back references. If the limit was reached in
+certain recursive cases it failed to be triggered and an internal error could
+be the result.
+
+36. The pcre2_dfa_match() function now takes note of the recursion limit for
+the internal recursive calls that are used for lookrounds and recursions within
+the pattern.
+
+37. More refactoring has got rid of the internal could_be_empty_branch()
+function (around 400 lines of code, including comments) by keeping track of
+could-be-emptiness as the pattern is compiled instead of scanning compiled
+groups. (This would have been much harder before the refactoring of #3 above.)
+This lifts a restriction on the number of branches in a group (more than about
+1100 would give "pattern is too complicated").
+
+38. Add the "-ac" command line option to pcre2test as a synonym for "-pattern
+auto_callout".
+
+39. In a library with Unicode support, incorrect data was compiled for a
+pattern with PCRE2_UCP set without PCRE2_UTF if a class required all wide
+characters to match (for example, /[\s[:^ascii:]]/).
+
+40. The callout_error modifier has been added to pcre2test to make it possible
+to return PCRE2_ERROR_CALLOUT from a callout.
+
+41. A minor change to pcre2grep: colour reset is now "<esc>[0m" instead of
+"<esc>[00m".
+
+42. The limit in the auto-possessification code that was intended to catch
+overly-complicated patterns and not spend too much time auto-possessifying was
+being reset too often, resulting in very long compile times for some patterns.
+Now such patterns are no longer completely auto-possessified.
+
+43. Applied Jason Hood's revised patch for RunTest.bat.
+
+44. Added a new Windows script RunGrepTest.bat, courtesy of Jason Hood.
+
+45. Minor cosmetic fix to pcre2test: move a variable that is not used under
+Windows into the "not Windows" code.
+
+46. Applied Jason Hood's patches to upgrade pcre2grep under Windows and tidy
+some of the code:
+
+  * normalised the Windows condition by ensuring WIN32 is defined;
+  * enables the callout feature under Windows;
+  * adds globbing (Microsoft's implementation expands quoted args),
+    using a tweaked opendirectory;
+  * implements the is_*_tty functions for Windows;
+  * --color=always will write the ANSI sequences to file;
+  * add sequences 4 (underline works on Win10) and 5 (blink as bright
+    background, relatively standard on DOS/Win);
+  * remove the (char *) casts for the now-const strings;
+  * remove GREP_COLOUR (grep's command line allowed the 'u', but not
+    the environment), parsing GREP_COLORS instead;
+  * uses the current colour if not set, rather than black;
+  * add print_match for the undefined case;
+  * fixes a typo.
+
+In addition, colour settings containing anything other than digits and
+semicolon are ignored, and the colour controls are no longer output for empty
+strings.
+
+47. Detecting patterns that are too large inside the length-measuring loop
+saves processing ridiculously long patterns to their end.
+
+48. Ignore PCRE2_CASELESS when processing \h, \H, \v, and \V in classes as it
+just wastes time. In the UTF case it can also produce redundant entries in
+XCLASS lists caused by characters with multiple other cases and pairs of
+characters in the same "not-x" sublists.
+
+49. A pattern such as /(?=(a\K))/ can report the end of the match being before
+its start; pcre2test was not handling this correctly when using the POSIX
+interface (it was OK with the native interface).
+
+50. In pcre2grep, ignore all JIT compile errors. This means that pcre2grep will
+continue to work, falling back to interpretation if anything goes wrong with
+JIT.
+
+51. Applied patches from Christian Persch to configure.ac to make use of the
+AC_USE_SYSTEM_EXTENSIONS macro and to test for functions used by the JIT
+modules.
+
+52. Minor fixes to pcre2grep from Jason Hood:
+    * fixed some spacing;
+    * Windows doesn't usually use single quotes, so I've added a define
+      to use appropriate quotes [in an example];
+    * LC_ALL was displayed as "LCC_ALL";
+    * numbers 11, 12 & 13 should end in "th";
+    * use double quotes in usage message.
+
+53. When autopossessifying, skip empty branches without recursion, to reduce
+stack usage for the benefit of clang with -fsanitize-address, which uses huge
+stack frames. Example pattern: /X?(R||){3335}/. Fixes oss-fuzz issue 553.
+
+54. A pattern with very many explicit back references to a group that is a long
+way from the start of the pattern could take a long time to compile because
+searching for the referenced group in order to find the minimum length was
+being done repeatedly. Now up to 128 group minimum lengths are cached and the
+attempt to find a minimum length is abandoned if there is a back reference to a
+group whose number is greater than 128. (In that case, the pattern is so
+complicated that this optimization probably isn't worth it.) This fixes
+oss-fuzz issue 557.
+
+55. Issue 32 for 10.22 below was not correctly fixed. If pcre2grep in multiline
+mode with --only-matching matched several lines, it restarted scanning at the
+next line instead of moving on to the end of the matched string, which can be
+several lines after the start.
+
+56. Applied Jason Hood's new patch for RunGrepTest.bat that updates it in line
+with updates to the non-Windows version.
+
+
+
+Version 10.22 29-July-2016
+--------------------------
+
+1. Applied Jason Hood's patches to RunTest.bat and testdata/wintestoutput3
+to fix problems with running the tests under Windows.
+
+2. Implemented a facility for quoting literal characters within hexadecimal
+patterns in pcre2test, to make it easier to create patterns with just a few
+non-printing characters.
+
+3. Binary zeros are not supported in pcre2test input files. It now detects them
+and gives an error.
+
+4. Updated the valgrind parameters in RunTest: (a) changed smc-check=all to
+smc-check=all-non-file; (b) changed obj:* in the suppression file to obj:??? so
+that it matches only unknown objects.
+
+5. Updated the maintenance script maint/ManyConfigTests to make it easier to
+select individual groups of tests.
+
+6. When the POSIX wrapper function regcomp() is called, the REG_NOSUB option
+used to set PCRE2_NO_AUTO_CAPTURE when calling pcre2_compile(). However, this
+disables the use of back references (and subroutine calls), which are supported
+by other implementations of regcomp() with RE_NOSUB. Therefore, REG_NOSUB no
+longer causes PCRE2_NO_AUTO_CAPTURE to be set, though it still ignores nmatch
+and pmatch when regexec() is called.
+
+7. Because of 6 above, pcre2test has been modified with a new modifier called
+posix_nosub, to call regcomp() with REG_NOSUB. Previously the no_auto_capture
+modifier had this effect. That option is now ignored when the POSIX API is in
+use.
+
+8. Minor tidies to the pcre2demo.c sample program, including more comments
+about its 8-bit-ness.
+
+9. Detect unmatched closing parentheses and give the error in the pre-scan
+instead of later. Previously the pre-scan carried on and could give a
+misleading incorrect error message. For example, /(?J)(?'a'))(?'a')/ gave a
+message about invalid duplicate group names.
+
+10. It has happened that pcre2test was accidentally linked with another POSIX
+regex library instead of libpcre2-posix. In this situation, a call to regcomp()
+(in the other library) may succeed, returning zero, but of course putting its
+own data into the regex_t block. In one example the re_pcre2_code field was
+left as NULL, which made pcre2test think it had not got a compiled POSIX regex,
+so it treated the next line as another pattern line, resulting in a confusing
+error message. A check has been added to pcre2test to see if the data returned
+from a successful call of regcomp() are valid for PCRE2's regcomp(). If they
+are not, an error message is output and the pcre2test run is abandoned. The
+message points out the possibility of a mis-linking. Hopefully this will avoid
+some head-scratching the next time this happens.
+
+11. A pattern such as /(?<=((?C)0))/, which has a callout inside a lookbehind
+assertion, caused pcre2test to output a very large number of spaces when the
+callout was taken, making the program appearing to loop.
+
+12. A pattern that included (*ACCEPT) in the middle of a sufficiently deeply
+nested set of parentheses of sufficient size caused an overflow of the
+compiling workspace (which was diagnosed, but of course is not desirable).
+
+13. Detect missing closing parentheses during the pre-pass for group
+identification.
+
+14. Changed some integer variable types and put in a number of casts, following
+a report of compiler warnings from Visual Studio 2013 and a few tests with
+gcc's -Wconversion (which still throws up a lot).
+
+15. Implemented pcre2_code_copy(), and added pushcopy and #popcopy to pcre2test
+for testing it.
+
+16. Change 66 for 10.21 introduced the use of snprintf() in PCRE2's version of
+regerror(). When the error buffer is too small, my version of snprintf() puts a
+binary zero in the final byte. Bug #1801 seems to show that other versions do
+not do this, leading to bad output from pcre2test when it was checking for
+buffer overflow. It no longer assumes a binary zero at the end of a too-small
+regerror() buffer.
+
+17. Fixed typo ("&&" for "&") in pcre2_study(). Fortunately, this could not
+actually affect anything, by sheer luck.
+
+18. Two minor fixes for MSVC compilation: (a) removal of apparently incorrect
+"const" qualifiers in pcre2test and (b) defining snprintf as _snprintf for
+older MSVC compilers. This has been done both in src/pcre2_internal.h for most
+of the library, and also in src/pcre2posix.c, which no longer includes
+pcre2_internal.h (see 24 below).
+
+19. Applied Chris Wilson's patch (Bugzilla #1681) to CMakeLists.txt for MSVC
+static compilation. Subsequently applied Chris Wilson's second patch, putting
+the first patch under a new option instead of being unconditional when
+PCRE_STATIC is set.
+
+20. Updated pcre2grep to set stdout as binary when run under Windows, so as not
+to convert \r\n at the ends of reflected lines into \r\r\n. This required
+ensuring that other output that is written to stdout (e.g. file names) uses the
+appropriate line terminator: \r\n for Windows, \n otherwise.
+
+21. When a line is too long for pcre2grep's internal buffer, show the maximum
+length in the error message.
+
+22. Added support for string callouts to pcre2grep (Zoltan's patch with PH
+additions).
+
+23. RunTest.bat was missing a "set type" line for test 22.
+
+24. The pcre2posix.c file was including pcre2_internal.h, and using some
+"private" knowledge of the data structures. This is unnecessary; the code has
+been re-factored and no longer includes pcre2_internal.h.
+
+25. A racing condition is fixed in JIT reported by Mozilla.
+
+26. Minor code refactor to avoid "array subscript is below array bounds"
+compiler warning.
+
+27. Minor code refactor to avoid "left shift of negative number" warning.
+
+28. Add a bit more sanity checking to pcre2_serialize_decode() and document
+that it expects trusted data.
+
+29. Fix typo in pcre2_jit_test.c
+
+30. Due to an oversight, pcre2grep was not making use of JIT when available.
+This is now fixed.
+
+31. The RunGrepTest script is updated to use the valgrind suppressions file
+when testing with JIT under valgrind (compare 10.21/51 below). The suppressions
+file is updated so that is now the same as for PCRE1: it suppresses the
+Memcheck warnings Addr16 and Cond in unknown objects (that is, JIT-compiled
+code). Also changed smc-check=all to smc-check=all-non-file as was done for
+RunTest (see 4 above).
+
+32. Implemented the PCRE2_NO_JIT option for pcre2_match().
+
+33. Fix typo that gave a compiler error when JIT not supported.
+
+34. Fix comment describing the returns from find_fixedlength().
+
+35. Fix potential negative index in pcre2test.
+
+36. Calls to pcre2_get_error_message() with error numbers that are never
+returned by PCRE2 functions were returning empty strings. Now the error code
+PCRE2_ERROR_BADDATA is returned. A facility has been added to pcre2test to
+show the texts for given error numbers (i.e. to call pcre2_get_error_message()
+and display what it returns) and a few representative error codes are now
+checked in RunTest.
+
+37. Added "&& !defined(__INTEL_COMPILER)" to the test for __GNUC__ in
+pcre2_match.c, in anticipation that this is needed for the same reason it was
+recently added to pcrecpp.cc in PCRE1.
+
+38. Using -o with -M in pcre2grep could cause unnecessary repeated output when
+the match extended over a line boundary, as it tried to find more matches "on
+the same line" - but it was already over the end.
+
+39. Allow \C in lookbehinds and DFA matching in UTF-32 mode (by converting it
+to the same code as '.' when PCRE2_DOTALL is set).
+
+40. Fix two clang compiler warnings in pcre2test when only one code unit width
+is supported.
+
+41. Upgrade RunTest to automatically re-run test 2 with a large (64M) stack if
+it fails when running the interpreter with a 16M stack (and if changing the
+stack size via pcre2test is possible). This avoids having to manually set a
+large stack size when testing with clang.
+
+42. Fix register overwite in JIT when SSE2 acceleration is enabled.
+
+43. Detect integer overflow in pcre2test pattern and data repetition counts.
+
+44. In pcre2test, ignore "allcaptures" after DFA matching.
+
+45. Fix unaligned accesses on x86. Patch by Marc Mutz.
+
+46. Fix some more clang compiler warnings.
+
+
+Version 10.21 12-January-2016
+-----------------------------
+
+1. Improve matching speed of patterns starting with + or * in JIT.
+
+2. Use memchr() to find the first character in an unanchored match in 8-bit
+mode in the interpreter. This gives a significant speed improvement.
+
+3. Removed a redundant copy of the opcode_possessify table in the
+pcre2_auto_possessify.c source.
+
+4. Fix typos in dftables.c for z/OS.
+
+5. Change 36 for 10.20 broke the handling of [[:>:]] and [[:<:]] in that
+processing them could involve a buffer overflow if the following character was
+an opening parenthesis.
+
+6. Change 36 for 10.20 also introduced a bug in processing this pattern:
+/((?x)(*:0))#(?'/. Specifically: if a setting of (?x) was followed by a (*MARK)
+setting (which (*:0) is), then (?x) did not get unset at the end of its group
+during the scan for named groups, and hence the external # was incorrectly
+treated as a comment and the invalid (?' at the end of the pattern was not
+diagnosed. This caused a buffer overflow during the real compile. This bug was
+discovered by Karl Skomski with the LLVM fuzzer.
+
+7. Moved the pcre2_find_bracket() function from src/pcre2_compile.c into its
+own source module to avoid a circular dependency between src/pcre2_compile.c
+and src/pcre2_study.c
+
+8. A callout with a string argument containing an opening square bracket, for
+example /(?C$[$)(?<]/, was incorrectly processed and could provoke a buffer
+overflow. This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+9. The handling of callouts during the pre-pass for named group identification
+has been tightened up.
+
+10. The quantifier {1} can be ignored, whether greedy, non-greedy, or
+possessive. This is a very minor optimization.
+
+11. A possessively repeated conditional group that could match an empty string,
+for example, /(?(R))*+/, was incorrectly compiled.
+
+12. The Unicode tables have been updated to Unicode 8.0.0 (thanks to Christian
+Persch).
+
+13. An empty comment (?#) in a pattern was incorrectly processed and could
+provoke a buffer overflow. This bug was discovered by Karl Skomski with the
+LLVM fuzzer.
+
+14. Fix infinite recursion in the JIT compiler when certain patterns such as
+/(?:|a|){100}x/ are analysed.
+
+15. Some patterns with character classes involving [: and \\ were incorrectly
+compiled and could cause reading from uninitialized memory or an incorrect
+error diagnosis. Examples are: /[[:\\](?<[::]/ and /[[:\\](?'abc')[a:]. The
+first of these bugs was discovered by Karl Skomski with the LLVM fuzzer.
+
+16. Pathological patterns containing many nested occurrences of [: caused
+pcre2_compile() to run for a very long time. This bug was found by the LLVM
+fuzzer.
+
+17. A missing closing parenthesis for a callout with a string argument was not
+being diagnosed, possibly leading to a buffer overflow. This bug was found by
+the LLVM fuzzer.
+
+18. A conditional group with only one branch has an implicit empty alternative
+branch and must therefore be treated as potentially matching an empty string.
+
+19. If (?R was followed by - or + incorrect behaviour happened instead of a
+diagnostic. This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+20. Another bug that was introduced by change 36 for 10.20: conditional groups
+whose condition was an assertion preceded by an explicit callout with a string
+argument might be incorrectly processed, especially if the string contained \Q.
+This bug was discovered by Karl Skomski with the LLVM fuzzer.
+
+21. Compiling PCRE2 with the sanitize options of clang showed up a number of
+very pedantic coding infelicities and a buffer overflow while checking a UTF-8
+string if the final multi-byte UTF-8 character was truncated.
+
+22. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
+class, where both values are literal letters in the same case, omit the
+non-letter EBCDIC code points within the range.
+
+23. Finding the minimum matching length of complex patterns with back
+references and/or recursions can take a long time. There is now a cut-off that
+gives up trying to find a minimum length when things get too complex.
+
+24. An optimization has been added that speeds up finding the minimum matching
+length for patterns containing repeated capturing groups or recursions.
+
+25. If a pattern contained a back reference to a group whose number was
+duplicated as a result of appearing in a (?|...) group, the computation of the
+minimum matching length gave a wrong result, which could cause incorrect "no
+match" errors. For such patterns, a minimum matching length cannot at present
+be computed.
+
+26. Added a check for integer overflow in conditions (?(<digits>) and
+(?(R<digits>). This omission was discovered by Karl Skomski with the LLVM
+fuzzer.
+
+27. Fixed an issue when \p{Any} inside an xclass did not read the current
+character.
+
+28. If pcre2grep was given the -q option with -c or -l, or when handling a
+binary file, it incorrectly wrote output to stdout.
+
+29. The JIT compiler did not restore the control verb head in case of *THEN
+control verbs. This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+30. The way recursive references such as (?3) are compiled has been re-written
+because the old way was the cause of many issues. Now, conversion of the group
+number into a pattern offset does not happen until the pattern has been
+completely compiled. This does mean that detection of all infinitely looping
+recursions is postponed till match time. In the past, some easy ones were
+detected at compile time. This re-writing was done in response to yet another
+bug found by the LLVM fuzzer.
+
+31. A test for a back reference to a non-existent group was missing for items
+such as \987. This caused incorrect code to be compiled. This issue was found
+by Karl Skomski with a custom LLVM fuzzer.
+
+32. Error messages for syntax errors following \g and \k were giving inaccurate
+offsets in the pattern.
+
+33. Improve the performance of starting single character repetitions in JIT.
+
+34. (*LIMIT_MATCH=) now gives an error instead of setting the value to 0.
+
+35. Error messages for syntax errors in *LIMIT_MATCH and *LIMIT_RECURSION now
+give the right offset instead of zero.
+
+36. The JIT compiler should not check repeats after a {0,1} repeat byte code.
+This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+37. The JIT compiler should restore the control chain for empty possessive
+repeats. This issue was found by Karl Skomski with a custom LLVM fuzzer.
+
+38. A bug which was introduced by the single character repetition optimization
+was fixed.
+
+39. Match limit check added to recursion. This issue was found by Karl Skomski
+with a custom LLVM fuzzer.
+
+40. Arrange for the UTF check in pcre2_match() and pcre2_dfa_match() to look
+only at the part of the subject that is relevant when the starting offset is
+non-zero.
+
+41. Improve first character match in JIT with SSE2 on x86.
+
+42. Fix two assertion fails in JIT. These issues were found by Karl Skomski
+with a custom LLVM fuzzer.
+
+43. Correct the setting of CMAKE_C_FLAGS in CMakeLists.txt (patch from Roy Ivy
+III).
+
+44. Fix bug in RunTest.bat for new test 14, and adjust the script for the added
+test (there are now 20 in total).
+
+45. Fixed a corner case of range optimization in JIT.
+
+46. Add the ${*MARK} facility to pcre2_substitute().
+
+47. Modifier lists in pcre2test were splitting at spaces without the required
+commas.
+
+48. Implemented PCRE2_ALT_VERBNAMES.
+
+49. Fixed two issues in JIT. These were found by Karl Skomski with a custom
+LLVM fuzzer.
+
+50. The pcre2test program has been extended by adding the #newline_default
+command. This has made it possible to run the standard tests when PCRE2 is
+compiled with either CR or CRLF as the default newline convention. As part of
+this work, the new command was added to several test files and the testing
+scripts were modified. The pcre2grep tests can now also be run when there is no
+LF in the default newline convention.
+
+51. The RunTest script has been modified so that, when JIT is used and valgrind
+is specified, a valgrind suppressions file is set up to ignore "Invalid read of
+size 16" errors because these are false positives when the hardware supports
+the SSE2 instruction set.
+
+52. It is now possible to have comment lines amid the subject strings in
+pcre2test (and perltest.sh) input.
+
+53. Implemented PCRE2_USE_OFFSET_LIMIT and pcre2_set_offset_limit().
+
+54. Add the null_context modifier to pcre2test so that calling pcre2_compile()
+and the matching functions with NULL contexts can be tested.
+
+55. Implemented PCRE2_SUBSTITUTE_EXTENDED.
+
+56. In a character class such as [\W\p{Any}] where both a negative-type escape
+("not a word character") and a property escape were present, the property
+escape was being ignored.
+
+57. Fixed integer overflow for patterns whose minimum matching length is very,
+very large.
+
+58. Implemented --never-backslash-C.
+
+59. Change 55 above introduced a bug by which certain patterns provoked the
+erroneous error "\ at end of pattern".
+
+60. The special sequences [[:<:]] and [[:>:]] gave rise to incorrect compiling
+errors or other strange effects if compiled in UCP mode. Found with libFuzzer
+and AddressSanitizer.
+
+61. Whitespace at the end of a pcre2test pattern line caused a spurious error
+message if there were only single-character modifiers. It should be ignored.
+
+62. The use of PCRE2_NO_AUTO_CAPTURE could cause incorrect compilation results
+or segmentation errors for some patterns. Found with libFuzzer and
+AddressSanitizer.
+
+63. Very long names in (*MARK) or (*THEN) etc. items could provoke a buffer
+overflow.
+
+64. Improve error message for overly-complicated patterns.
+
+65. Implemented an optional replication feature for patterns in pcre2test, to
+make it easier to test long repetitive patterns. The tests for 63 above are
+converted to use the new feature.
+
+66. In the POSIX wrapper, if regerror() was given too small a buffer, it could
+misbehave.
+
+67. In pcre2_substitute() in UTF mode, the UTF validity check on the
+replacement string was happening before the length setting when the replacement
+string was zero-terminated.
+
+68. In pcre2_substitute() in UTF mode, PCRE2_NO_UTF_CHECK can be set for the
+second and subsequent calls to pcre2_match().
+
+69. There was no check for integer overflow for a replacement group number in
+pcre2_substitute(). An added check for a number greater than the largest group
+number in the pattern means this is not now needed.
+
+70. The PCRE2-specific VERSION condition didn't work correctly if only one
+digit was given after the decimal point, or if more than two digits were given.
+It now works with one or two digits, and gives a compile time error if more are
+given.
+
+71. In pcre2_substitute() there was the possibility of reading one code unit
+beyond the end of the replacement string.
+
+72. The code for checking a subject's UTF-32 validity for a pattern with a
+lookbehind involved an out-of-bounds pointer, which could potentially cause
+trouble in some environments.
+
+73. The maximum lookbehind length was incorrectly calculated for patterns such
+as /(?<=(a)(?-1))x/ which have a recursion within a backreference.
+
+74. Give an error if a lookbehind assertion is longer than 65535 code units.
+
+75. Give an error in pcre2_substitute() if a match ends before it starts (as a
+result of the use of \K).
+
+76. Check the length of subpattern names and the names in (*MARK:xx) etc.
+dynamically to avoid the possibility of integer overflow.
+
+77. Implement pcre2_set_max_pattern_length() so that programs can restrict the
+size of patterns that they are prepared to handle.
+
+78. (*NO_AUTO_POSSESS) was not working.
+
+79. Adding group information caching improves the speed of compiling when
+checking whether a group has a fixed length and/or could match an empty string,
+especially when recursion or subroutine calls are involved. However, this
+cannot be used when (?| is present in the pattern because the same number may
+be used for groups of different sizes. To catch runaway patterns in this
+situation, counts have been introduced to the functions that scan for empty
+branches or compute fixed lengths.
+
+80. Allow for the possibility of the size of the nest_save structure not being
+a factor of the size of the compiling workspace (it currently is).
+
+81. Check for integer overflow in minimum length calculation and cap it at
+65535.
+
+82. Small optimizations in code for finding the minimum matching length.
+
+83. Lock out configuring for EBCDIC with non-8-bit libraries.
+
+84. Test for error code <= 0 in regerror().
+
+85. Check for too many replacements (more than INT_MAX) in pcre2_substitute().
+
+86. Avoid the possibility of computing with an out-of-bounds pointer (though
+not dereferencing it) while handling lookbehind assertions.
+
+87. Failure to get memory for the match data in regcomp() is now given as a
+regcomp() error instead of waiting for regexec() to pick it up.
+
+88. In pcre2_substitute(), ensure that CRLF is not split when it is a valid
+newline sequence.
+
+89. Paranoid check in regcomp() for bad error code from pcre2_compile().
+
+90. Run test 8 (internal offsets and code sizes) for link sizes 3 and 4 as well
+as for link size 2.
+
+91. Document that JIT has a limit on pattern size, and give more information
+about JIT compile failures in pcre2test.
+
+92. Implement PCRE2_INFO_HASBACKSLASHC.
+
+93. Re-arrange valgrind support code in pcre2test to avoid spurious reports
+with JIT (possibly caused by SSE2?).
+
+94. Support offset_limit in JIT.
+
+95. A sequence such as [[:punct:]b] that is, a POSIX character class followed
+by a single ASCII character in a class item, was incorrectly compiled in UCP
+mode. The POSIX class got lost, but only if the single character followed it.
+
+96. [:punct:] in UCP mode was matching some characters in the range 128-255
+that should not have been matched.
+
+97. If [:^ascii:] or [:^xdigit:] are present in a non-negated class, all
+characters with code points greater than 255 are in the class. When a Unicode
+property was also in the class (if PCRE2_UCP is set, escapes such as \w are
+turned into Unicode properties), wide characters were not correctly handled,
+and could fail to match.
+
+98. In pcre2test, make the "startoffset" modifier a synonym of "offset",
+because it sets the "startoffset" parameter for pcre2_match().
+
+99. If PCRE2_AUTO_CALLOUT was set on a pattern that had a (?# comment between
+an item and its qualifier (for example, A(?#comment)?B) pcre2_compile()
+misbehaved. This bug was found by the LLVM fuzzer.
+
+100. The error for an invalid UTF pattern string always gave the code unit
+offset as zero instead of where the invalidity was found.
+
+101. Further to 97 above, negated classes such as [^[:^ascii:]\d] were also not
+working correctly in UCP mode.
+
+102. Similar to 99 above, if an isolated \E was present between an item and its
+qualifier when PCRE2_AUTO_CALLOUT was set, pcre2_compile() misbehaved. This bug
+was found by the LLVM fuzzer.
+
+103. The POSIX wrapper function regexec() crashed if the option REG_STARTEND
+was set when the pmatch argument was NULL. It now returns REG_INVARG.
+
+104. Allow for up to 32-bit numbers in the ordin() function in pcre2grep.
+
+105. An empty \Q\E sequence between an item and its qualifier caused
+pcre2_compile() to misbehave when auto callouts were enabled. This bug
+was found by the LLVM fuzzer.
+
+106. If both PCRE2_ALT_VERBNAMES and PCRE2_EXTENDED were set, and a (*MARK) or
+other verb "name" ended with whitespace immediately before the closing
+parenthesis, pcre2_compile() misbehaved. Example: /(*:abc )/, but only when
+both those options were set.
+
+107. In a number of places pcre2_compile() was not handling NULL characters
+correctly, and pcre2test with the "bincode" modifier was not always correctly
+displaying fields containing NULLS:
+
+   (a) Within /x extended #-comments
+   (b) Within the "name" part of (*MARK) and other *verbs
+   (c) Within the text argument of a callout
+
+108. If a pattern that was compiled with PCRE2_EXTENDED started with white
+space or a #-type comment that was followed by (?-x), which turns off
+PCRE2_EXTENDED, and there was no subsequent (?x) to turn it on again,
+pcre2_compile() assumed that (?-x) applied to the whole pattern and
+consequently mis-compiled it. This bug was found by the LLVM fuzzer. The fix
+for this bug means that a setting of any of the (?imsxJU) options at the start
+of a pattern is no longer transferred to the options that are returned by
+PCRE2_INFO_ALLOPTIONS. In fact, this was an anachronism that should have
+changed when the effects of those options were all moved to compile time.
+
+109. An escaped closing parenthesis in the "name" part of a (*verb) when
+PCRE2_ALT_VERBNAMES was set caused pcre2_compile() to malfunction. This bug
+was found by the LLVM fuzzer.
+
+110. Implemented PCRE2_SUBSTITUTE_UNSET_EMPTY, and updated pcre2test to make it
+possible to test it.
+
+111. "Harden" pcre2test against ridiculously large values in modifiers and
+command line arguments.
+
+112. Implemented PCRE2_SUBSTITUTE_UNKNOWN_UNSET and PCRE2_SUBSTITUTE_OVERFLOW_
+LENGTH.
+
+113. Fix printing of *MARK names that contain binary zeroes in pcre2test.
+
+
+Version 10.20 30-June-2015
+--------------------------
+
+1. Callouts with string arguments have been added.
+
+2. Assertion code generator in JIT has been optimized.
+
+3. The invalid pattern (?(?C) has a missing assertion condition at the end. The
+pcre2_compile() function read past the end of the input before diagnosing an
+error. This bug was discovered by the LLVM fuzzer.
+
+4. Implemented pcre2_callout_enumerate().
+
+5. Fix JIT compilation of conditional blocks whose assertion is converted to
+(*FAIL). E.g: /(?(?!))/.
+
+6. The pattern /(?(?!)^)/ caused references to random memory. This bug was
+discovered by the LLVM fuzzer.
+
+7. The assertion (?!) is optimized to (*FAIL). This was not handled correctly
+when this assertion was used as a condition, for example (?(?!)a|b). In
+pcre2_match() it worked by luck; in pcre2_dfa_match() it gave an incorrect
+error about an unsupported item.
+
+8. For some types of pattern, for example /Z*(|d*){216}/, the auto-
+possessification code could take exponential time to complete. A recursion
+depth limit of 1000 has been imposed to limit the resources used by this
+optimization. This infelicity was discovered by the LLVM fuzzer.
+
+9. A pattern such as /(*UTF)[\S\V\H]/, which contains a negated special class
+such as \S in non-UCP mode, explicit wide characters (> 255) can be ignored
+because \S ensures they are all in the class. The code for doing this was
+interacting badly with the code for computing the amount of space needed to
+compile the pattern, leading to a buffer overflow. This bug was discovered by
+the LLVM fuzzer.
+
+10. A pattern such as /((?2)+)((?1))/ which has mutual recursion nested inside
+other kinds of group caused stack overflow at compile time. This bug was
+discovered by the LLVM fuzzer.
+
+11. A pattern such as /(?1)(?#?'){8}(a)/ which had a parenthesized comment
+between a subroutine call and its quantifier was incorrectly compiled, leading
+to buffer overflow or other errors. This bug was discovered by the LLVM fuzzer.
+
+12. The illegal pattern /(?(?<E>.*!.*)?)/ was not being diagnosed as missing an
+assertion after (?(. The code was failing to check the character after (?(?<
+for the ! or = that would indicate a lookbehind assertion. This bug was
+discovered by the LLVM fuzzer.
+
+13. A pattern such as /X((?2)()*+){2}+/ which has a possessive quantifier with
+a fixed maximum following a group that contains a subroutine reference was
+incorrectly compiled and could trigger buffer overflow. This bug was discovered
+by the LLVM fuzzer.
+
+14. Negative relative recursive references such as (?-7) to non-existent
+subpatterns were not being diagnosed and could lead to unpredictable behaviour.
+This bug was discovered by the LLVM fuzzer.
+
+15. The bug fixed in 14 was due to an integer variable that was unsigned when
+it should have been signed. Some other "int" variables, having been checked,
+have either been changed to uint32_t or commented as "must be signed".
+
+16. A mutual recursion within a lookbehind assertion such as (?<=((?2))((?1)))
+caused a stack overflow instead of the diagnosis of a non-fixed length
+lookbehind assertion. This bug was discovered by the LLVM fuzzer.
+
+17. The use of \K in a positive lookbehind assertion in a non-anchored pattern
+(e.g. /(?<=\Ka)/) could make pcre2grep loop.
+
+18. There was a similar problem to 17 in pcre2test for global matches, though
+the code there did catch the loop.
+
+19. If a greedy quantified \X was preceded by \C in UTF mode (e.g. \C\X*),
+and a subsequent item in the pattern caused a non-match, backtracking over the
+repeated \X did not stop, but carried on past the start of the subject, causing
+reference to random memory and/or a segfault. There were also some other cases
+where backtracking after \C could crash. This set of bugs was discovered by the
+LLVM fuzzer.
+
+20. The function for finding the minimum length of a matching string could take
+a very long time if mutual recursion was present many times in a pattern, for
+example, /((?2){73}(?2))((?1))/. A better mutual recursion detection method has
+been implemented. This infelicity was discovered by the LLVM fuzzer.
+
+21. Implemented PCRE2_NEVER_BACKSLASH_C.
+
+22. The feature for string replication in pcre2test could read from freed
+memory if the replication required a buffer to be extended, and it was not
+working properly in 16-bit and 32-bit modes. This issue was discovered by a
+fuzzer: see http://lcamtuf.coredump.cx/afl/.
+
+23. Added the PCRE2_ALT_CIRCUMFLEX option.
+
+24. Adjust the treatment of \8 and \9 to be the same as the current Perl
+behaviour.
+
+25. Static linking against the PCRE2 library using the pkg-config module was
+failing on missing pthread symbols.
+
+26. If a group that contained a recursive back reference also contained a
+forward reference subroutine call followed by a non-forward-reference
+subroutine call, for example /.((?2)(?R)\1)()/, pcre2_compile() failed to
+compile correct code, leading to undefined behaviour or an internally detected
+error. This bug was discovered by the LLVM fuzzer.
+
+27. Quantification of certain items (e.g. atomic back references) could cause
+incorrect code to be compiled when recursive forward references were involved.
+For example, in this pattern: /(?1)()((((((\1++))\x85)+)|))/. This bug was
+discovered by the LLVM fuzzer.
+
+28. A repeated conditional group whose condition was a reference by name caused
+a buffer overflow if there was more than one group with the given name. This
+bug was discovered by the LLVM fuzzer.
+
+29. A recursive back reference by name within a group that had the same name as
+another group caused a buffer overflow. For example: /(?J)(?'d'(?'d'\g{d}))/.
+This bug was discovered by the LLVM fuzzer.
+
+30. A forward reference by name to a group whose number is the same as the
+current group, for example in this pattern: /(?|(\k'Pm')|(?'Pm'))/, caused a
+buffer overflow at compile time. This bug was discovered by the LLVM fuzzer.
+
+31. Fix -fsanitize=undefined warnings for left shifts of 1 by 31 (it treats 1
+as an int; fixed by writing it as 1u).
+
+32. Fix pcre2grep compile when -std=c99 is used with gcc, though it still gives
+a warning for "fileno" unless -std=gnu99 us used.
+
+33. A lookbehind assertion within a set of mutually recursive subpatterns could
+provoke a buffer overflow. This bug was discovered by the LLVM fuzzer.
+
+34. Give an error for an empty subpattern name such as (?'').
+
+35. Make pcre2test give an error if a pattern that follows #forbud_utf contains
+\P, \p, or \X.
+
+36. The way named subpatterns are handled has been refactored. There is now a
+pre-pass over the regex which does nothing other than identify named
+subpatterns and count the total captures. This means that information about
+named patterns is known before the rest of the compile. In particular, it means
+that forward references can be checked as they are encountered. Previously, the
+code for handling forward references was contorted and led to several errors in
+computing the memory requirements for some patterns, leading to buffer
+overflows.
+
+37. There was no check for integer overflow in subroutine calls such as (?123).
+
+38. The table entry for \l in EBCDIC environments was incorrect, leading to its
+being treated as a literal 'l' instead of causing an error.
+
+39. If a non-capturing group containing a conditional group that could match
+an empty string was repeated, it was not identified as matching an empty string
+itself. For example: /^(?:(?(1)x|)+)+$()/.
+
+40. In an EBCDIC environment, pcretest was mishandling the escape sequences
+\a and \e in test subject lines.
+
+41. In an EBCDIC environment, \a in a pattern was converted to the ASCII
+instead of the EBCDIC value.
+
+42. The handling of \c in an EBCDIC environment has been revised so that it is
+now compatible with the specification in Perl's perlebcdic page.
+
+43. Single character repetition in JIT has been improved. 20-30% speedup
+was achieved on certain patterns.
+
+44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
+ASCII/Unicode. This has now been added to the list of characters that are
+recognized as white space in EBCDIC.
+
+45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave
+an error (correctly) when used outside a class, but did not give an error
+within a class.
+
+46. \h within a class was incorrectly compiled in EBCDIC environments.
+
+47. JIT should return with error when the compiled pattern requires
+more stack space than the maximum.
+
+48. Fixed a memory leak in pcre2grep when a locale is set.

+Version 10.10 06-March-2015
+---------------------------
+
+1. When a pattern is compiled, it remembers the highest back reference so that
+when matching, if the ovector is too small, extra memory can be obtained to
+use instead. A conditional subpattern whose condition is a check on a capture
+having happened, such as, for example in the pattern /^(?:(a)|b)(?(1)A|B)/, is
+another kind of back reference, but it was not setting the highest
+backreference number. This mattered only if pcre2_match() was called with an
+ovector that was too small to hold the capture, and there was no other kind of
+back reference (a situation which is probably quite rare). The effect of the
+bug was that the condition was always treated as FALSE when the capture could
+not be consulted, leading to a incorrect behaviour by pcre2_match(). This bug
+has been fixed.
+
+2. Functions for serialization and deserialization of sets of compiled patterns
+have been added.
+
+3. The value that is returned by PCRE2_INFO_SIZE has been corrected to remove
+excess code units at the end of the data block that may occasionally occur if
+the code for calculating the size over-estimates. This change stops the
+serialization code copying uninitialized data, to which valgrind objects. The
+documentation of PCRE2_INFO_SIZE was incorrect in stating that the size did not
+include the general overhead. This has been corrected.
+
+4. All code units in every slot in the table of group names are now set, again
+in order to avoid accessing uninitialized data when serializing.
+
+5. The (*NO_JIT) feature is implemented.
+
+6. If a bug that caused pcre2_compile() to use more memory than allocated was
+triggered when using valgrind, the code in (3) above passed a stupidly large
+value to valgrind. This caused a crash instead of an "internal error" return.
+
+7. A reference to a duplicated named group (either a back reference or a test
+for being set in a conditional) that occurred in a part of the pattern where
+PCRE2_DUPNAMES was not set caused the amount of memory needed for the pattern
+to be incorrectly calculated, leading to overwriting.
+
+8. A mutually recursive set of back references such as (\2)(\1) caused a
+segfault at compile time (while trying to find the minimum matching length).
+The infinite loop is now broken (with the minimum length unset, that is, zero).
+
+9. If an assertion that was used as a condition was quantified with a minimum
+of zero, matching went wrong. In particular, if the whole group had unlimited
+repetition and could match an empty string, a segfault was likely. The pattern
+(?(?=0)?)+ is an example that caused this. Perl allows assertions to be
+quantified, but not if they are being used as conditions, so the above pattern
+is faulted by Perl. PCRE2 has now been changed so that it also rejects such
+patterns.
+
+10. The error message for an invalid quantifier has been changed from "nothing
+to repeat" to "quantifier does not follow a repeatable item".
+
+11. If a bad UTF string is compiled with NO_UTF_CHECK, it may succeed, but
+scanning the compiled pattern in subsequent auto-possessification can get out
+of step and lead to an unknown opcode. Previously this could have caused an
+infinite loop. Now it generates an "internal error" error. This is a tidyup,
+not a bug fix; passing bad UTF with NO_UTF_CHECK is documented as having an
+undefined outcome.
+
+12. A UTF pattern containing a "not" match of a non-ASCII character and a
+subroutine reference could loop at compile time. Example: /[^\xff]((?1))/.
+
+13. The locale test (RunTest 3) has been upgraded. It now checks that a locale
+that is found in the output of "locale -a" can actually be set by pcre2test
+before it is accepted. Previously, in an environment where a locale was listed
+but would not set (an example does exist), the test would "pass" without
+actually doing anything. Also the fr_CA locale has been added to the list of
+locales that can be used.
+
+14. Fixed a bug in pcre2_substitute(). If a replacement string ended in a
+capturing group number without parentheses, the last character was incorrectly
+literally included at the end of the replacement string.
+
+15. A possessive capturing group such as (a)*+ with a minimum repeat of zero
+failed to allow the zero-repeat case if pcre2_match() was called with an
+ovector too small to capture the group.
+
+16. Improved error message in pcre2test when setting the stack size (-S) fails.
+
+17. Fixed two bugs in CMakeLists.txt: (1) Some lines had got lost in the
+transfer from PCRE1, meaning that CMake configuration failed if "build tests"
+was selected. (2) The file src/pcre2_serialize.c had not been added to the list
+of PCRE2 sources, which caused a failure to build pcre2test.
+
+18. Fixed typo in pcre2_serialize.c (DECL instead of DEFN) that causes problems
+only on Windows.
+
+19. Use binary input when reading back saved serialized patterns in pcre2test.
+
+20. Added RunTest.bat for running the tests under Windows.
+
+21. "make distclean" was not removing config.h, a file that may be created for
+use with CMake.
+
+22. A pattern such as "((?2){0,1999}())?", which has a group containing a
+forward reference repeated a large (but limited) number of times within a
+repeated outer group that has a zero minimum quantifier, caused incorrect code
+to be compiled, leading to the error "internal error: previously-checked
+referenced subpattern not found" when an incorrect memory address was read.
+This bug was reported as "heap overflow", discovered by Kai Lu of Fortinet's
+FortiGuard Labs. (Added 24-March-2015: CVE-2015-2325 was given to this.)
+
+23. A pattern such as "((?+1)(\1))/" containing a forward reference subroutine
+call within a group that also contained a recursive back reference caused
+incorrect code to be compiled. This bug was reported as "heap overflow",
+discovered by Kai Lu of Fortinet's FortiGuard Labs. (Added 24-March-2015:
+CVE-2015-2326 was given to this.)
+
+24. Computing the size of the JIT read-only data in advance has been a source
+of various issues, and new ones are still appear unfortunately. To fix
+existing and future issues, size computation is eliminated from the code,
+and replaced by on-demand memory allocation.
+
+25. A pattern such as /(?i)[A-`]/, where characters in the other case are
+adjacent to the end of the range, and the range contained characters with more
+than one other case, caused incorrect behaviour when compiled in UTF mode. In
+that example, the range a-j was left out of the class.
+
+
+Version 10.00 05-January-2015
+-----------------------------
+
+Version 10.00 is the first release of PCRE2, a revised API for the PCRE
+library. Changes prior to 10.00 are logged in the ChangeLog file for the old
+API, up to item 20 for release 8.36.
+
+The code of the library was heavily revised as part of the new API
+implementation. Details of each and every modification were not individually
+logged. In addition to the API changes, the following changes were made. They
+are either new functionality, or bug fixes and other noticeable changes of
+behaviour that were implemented after the code had been forked.
+
+1. Including Unicode support at build time is now enabled by default, but it
+can optionally be disabled. It is not enabled by default at run time (no
+change).
+
+2. The test program, now called pcre2test, was re-specified and almost
+completely re-written. Its input is not compatible with input for pcretest.
+
+3. Patterns may start with (*NOTEMPTY) or (*NOTEMPTY_ATSTART) to set the
+PCRE2_NOTEMPTY or PCRE2_NOTEMPTY_ATSTART options for every subject line that is
+matched by that pattern.
+
+4. For the benefit of those who use PCRE2 via some other application, that is,
+not writing the function calls themselves, it is possible to check the PCRE2
+version by matching a pattern such as /(?(VERSION>=10)yes|no)/ against a
+string such as "yesno".
+
+5. There are case-equivalent Unicode characters whose encodings use different
+numbers of code units in UTF-8. U+023A and U+2C65 are one example. (It is
+theoretically possible for this to happen in UTF-16 too.) If a backreference to
+a group containing one of these characters was greedily repeated, and during
+the match a backtrack occurred, the subject might be backtracked by the wrong
+number of code units. For example, if /^(\x{23a})\1*(.)/ is matched caselessly
+(and in UTF-8 mode) against "\x{23a}\x{2c65}\x{2c65}\x{2c65}", group 2 should
+capture the final character, which is the three bytes E2, B1, and A5 in UTF-8.
+Incorrect backtracking meant that group 2 captured only the last two bytes.
+This bug has been fixed; the new code is slower, but it is used only when the
+strings matched by the repetition are not all the same length.
+
+6. A pattern such as /()a/ was not setting the "first character must be 'a'"
+information. This applied to any pattern with a group that matched no
+characters, for example: /(?:(?=.)|(?<!x))a/.
+
+7. When an (*ACCEPT) is triggered inside capturing parentheses, it arranges for
+those parentheses to be closed with whatever has been captured so far. However,
+it was failing to mark any other groups between the highest capture so far and
+the currrent group as "unset". Thus, the ovector for those groups contained
+whatever was previously there. An example is the pattern /(x)|((*ACCEPT))/ when
+matched against "abcd".
+
+8. The pcre2_substitute() function has been implemented.
+
+9. If an assertion used as a condition was quantified with a minimum of zero
+(an odd thing to do, but it happened), SIGSEGV or other misbehaviour could
+occur.
+
+10. The PCRE2_NO_DOTSTAR_ANCHOR option has been implemented.

+Technical Notes about PCRE2
+---------------------------
+
+These are very rough technical notes that record potentially useful information
+about PCRE2 internals. PCRE2 is a library based on the original PCRE library,
+but with a revised (and incompatible) API. To avoid confusion, the original
+library is referred to as PCRE1 below. For information about testing PCRE2, see
+the pcre2test documentation and the comment at the head of the RunTest file.
+
+PCRE1 releases were up to 8.3x when PCRE2 was developed, and later bug fix
+releases remain in the 8.xx series. PCRE2 releases started at 10.00 to avoid
+confusion with PCRE1.
+
+
+Historical note 1
+-----------------
+
+Many years ago I implemented some regular expression functions to an algorithm
+suggested by Martin Richards. The rather simple patterns were not Unix-like in
+form, and were quite restricted in what they could do by comparison with Perl.
+The interesting part about the algorithm was that the amount of space required
+to hold the compiled form of an expression was known in advance. The code to
+apply an expression did not operate by backtracking, as the original Henry
+Spencer code and current PCRE2 and Perl code does, but instead checked all
+possibilities simultaneously by keeping a list of current states and checking
+all of them as it advanced through the subject string. In the terminology of
+Jeffrey Friedl's book, it was a "DFA algorithm", though it was not a
+traditional Finite State Machine (FSM). When the pattern was all used up, all
+remaining states were possible matches, and the one matching the longest subset
+of the subject string was chosen. This did not necessarily maximize the
+individual wild portions of the pattern, as is expected in Unix and Perl-style
+regular expressions.
+
+
+Historical note 2
+-----------------
+
+By contrast, the code originally written by Henry Spencer (which was
+subsequently heavily modified for Perl) compiles the expression twice: once in
+a dummy mode in order to find out how much store will be needed, and then for
+real. (The Perl version probably doesn't do this any more; I'm talking about
+the original library.) The execution function operates by backtracking and
+maximizing (or, optionally, minimizing, in Perl) the amount of the subject that
+matches individual wild portions of the pattern. This is an "NFA algorithm" in
+Friedl's terminology.
+
+
+OK, here's the real stuff
+-------------------------
+
+For the set of functions that formed the original PCRE1 library in 1997 (which
+are unrelated to those mentioned above), I tried at first to invent an
+algorithm that used an amount of store bounded by a multiple of the number of
+characters in the pattern, to save on compiling time. However, because of the
+greater complexity in Perl regular expressions, I couldn't do this, even though
+the then current Perl 5.004 patterns were much simpler than those supported
+nowadays. In any case, a first pass through the pattern is helpful for other
+reasons.
+
+
+Support for 16-bit and 32-bit data strings
+-------------------------------------------
+
+The PCRE2 library can be compiled in any combination of 8-bit, 16-bit or 32-bit
+modes, creating up to three different libraries. In the description that
+follows, the word "short" is used for a 16-bit data quantity, and the phrase
+"code unit" is used for a quantity that is a byte in 8-bit mode, a short in
+16-bit mode and a 32-bit word in 32-bit mode. The names of PCRE2 functions are
+given in generic form, without the _8, _16, or _32 suffix.
+
+
+Computing the memory requirement: how it was
+--------------------------------------------
+
+Up to and including release 6.7, PCRE1 worked by running a very degenerate
+first pass to calculate a maximum memory requirement, and then a second pass to
+do the real compile - which might use a bit less than the predicted amount of
+memory. The idea was that this would turn out faster than the Henry Spencer
+code because the first pass is degenerate and the second pass can just store
+stuff straight into memory, which it knows is big enough.
+
+
+Computing the memory requirement: how it is
+-------------------------------------------
+
+By the time I was working on a potential 6.8 release, the degenerate first pass
+had become very complicated and hard to maintain. Indeed one of the early
+things I did for 6.8 was to fix Yet Another Bug in the memory computation. Then
+I had a flash of inspiration as to how I could run the real compile function in
+a "fake" mode that enables it to compute how much memory it would need, while
+in most cases only ever using a small amount of working memory, and without too
+many tests of the mode that might slow it down. So I refactored the compiling
+functions to work this way. This got rid of about 600 lines of source and made
+further maintenance and development easier. As this was such a major change, I
+never released 6.8, instead upping the number to 7.0 (other quite major changes
+were also present in the 7.0 release).
+
+A side effect of this work was that the previous limit of 200 on the nesting
+depth of parentheses was removed. However, there was a downside: compiling ran
+more slowly than before (30% or more, depending on the pattern) because it now
+did a full analysis of the pattern. My hope was that this would not be a big
+issue, and in the event, nobody has commented on it.
+
+At release 8.34, a limit on the nesting depth of parentheses was re-introduced
+(default 250, settable at build time) so as to put a limit on the amount of
+system stack used by the compile function, which uses recursive function calls
+for nested parenthesized groups. This is a safety feature for environments with
+small stacks where the patterns are provided by users.
+
+
+Yet another pattern scan
+------------------------
+
+History repeated itself for PCRE2 release 10.20. A number of bugs relating to
+named subpatterns had been discovered by fuzzers. Most of these were related to
+the handling of forward references when it was not known if the named group was
+unique. (References to non-unique names use a different opcode and more
+memory.) The use of duplicate group numbers (the (?| facility) also caused
+issues.
+
+To get around these problems I adopted a new approach by adding a third pass
+over the pattern (really a "pre-pass"), which did nothing other than identify
+all the named subpatterns and their corresponding group numbers. This means
+that the actual compile (both the memory-computing dummy run and the real
+compile) has full knowledge of group names and numbers throughout. Several
+dozen lines of messy code were eliminated, though the new pre-pass was not
+short. In particular, parsing and skipping over [] classes is complicated.
+
+While working on 10.22 I realized that I could simplify yet again by moving
+more of the parsing into the pre-pass, thus avoiding doing it in two places, so
+after 10.22 was released, the code underwent yet another big refactoring. This
+is how it is from 10.23 onwards:
+
+The function called parse_regex() scans the pattern characters, parsing them
+into literal data and meta characters. It converts escapes such as \x{123}
+into literals, handles \Q...\E, and skips over comments and non-significant
+white space. The result of the scanning is put into a vector of 32-bit unsigned
+integers. Values less than 0x80000000 are literal data. Higher values represent
+meta-characters. The top 16-bits of such values identify the meta-character,
+and these are given names such as META_CAPTURE. The lower 16-bits are available
+for data, for example, the capturing group number. The only situation in which
+literal data values greater than 0x7fffffff can appear is when the 32-bit
+library is running in non-UTF mode. This is handled by having a special
+meta-character that is followed by the 32-bit data value.
+
+The size of the parsed pattern vector, when auto-callouts are not enabled, is
+bounded by the length of the pattern (with one exception). The code is written
+so that each item in the pattern uses no more vector elements than the number
+of code units in the item itself. The exception is the aforementioned large
+32-bit number handling. For this reason, 32-bit non-UTF patterns are scanned in
+advance to check for such values. When auto-callouts are enabled, the generous
+assumption is made that there will be a callout for each pattern code unit
+(which of course is only actually true if all code units are literals) plus one
+at the end. There is a default parsed pattern vector on the system stack, but
+if this is not big enough, heap memory is used.
+
+As before, the actual compiling function is run twice, the first time to
+determine the amount of memory needed for the final compiled pattern. It
+now processes the parsed pattern vector, not the pattern itself, although some
+of the parsed items refer to strings in the pattern - for example, group
+names. As escapes and comments have already been processed, the code is a bit
+simpler than before.
+
+Most errors can be diagnosed during the parsing scan. For those that cannot
+(for example, "lookbehind assertion is not fixed length"), the parsed code
+contains offsets into the pattern so that the actual compiling code can
+report where errors are.
+
+
+The elements of the parsed pattern vector
+-----------------------------------------
+
+The word "offset" below means a code unit offset into the pattern. When
+PCRE2_SIZE (which is usually size_t) is no bigger than uint32_t, an offset is
+stored in a single parsed pattern element. Otherwise (typically on 64-bit
+systems) it occupies two elements. The following meta items occupy just one
+element, with no data:
+
+META_ACCEPT           (*ACCEPT)
+META_ASTERISK         *
+META_ASTERISK_PLUS    *+
+META_ASTERISK_QUERY   *?
+META_ATOMIC           (?> start of atomic group
+META_CIRCUMFLEX       ^ metacharacter
+META_CLASS            [ start of non-empty class
+META_CLASS_EMPTY      [] empty class - only with PCRE2_ALLOW_EMPTY_CLASS
+META_CLASS_EMPTY_NOT  [^] negative empty class - ditto
+META_CLASS_END        ] end of non-empty class
+META_CLASS_NOT        [^ start non-empty negative class
+META_COMMIT           (*COMMIT)
+META_COND_ASSERT      (?(?assertion)
+META_DOLLAR           $ metacharacter
+META_DOT              . metacharacter
+META_END              End of pattern (this value is 0x80000000)
+META_FAIL             (*FAIL)
+META_KET              ) closing parenthesis
+META_LOOKAHEAD        (?= start of lookahead
+META_LOOKAHEADNOT     (?! start of negative lookahead
+META_NOCAPTURE        (?: no capture parens
+META_PLUS             +
+META_PLUS_PLUS        ++
+META_PLUS_QUERY       +?
+META_PRUNE            (*PRUNE) - no argument
+META_QUERY            ?
+META_QUERY_PLUS       ?+
+META_QUERY_QUERY      ??
+META_RANGE_ESCAPED    hyphen in class range with at least one escape
+META_RANGE_LITERAL    hyphen in class range defined literally
+META_SKIP             (*SKIP) - no argument
+META_THEN             (*THEN) - no argument
+
+The two RANGE values occur only in character classes. They are positioned
+between two literals that define the start and end of the range. In an EBCDIC
+evironment it is necessary to know whether either of the range values was
+specified as an escape. In an ASCII/Unicode environment the distinction is not
+relevant.
+
+The following have data in the lower 16 bits, and may be followed by other data
+elements:
+
+META_ALT              | alternation
+META_BACKREF          back reference
+META_CAPTURE          start of capturing group
+META_ESCAPE           non-literal escape sequence
+META_RECURSE          recursion call
+
+If the data for META_ALT is non-zero, it is inside a lookbehind, and the data
+is the length of its branch, for which OP_REVERSE must be generated.
+
+META_BACKREF, META_CAPTURE, and META_RECURSE have the capture group number as
+their data in the lower 16 bits of the element.
+
+META_BACKREF is followed by an offset if the back reference group number is 10
+or more. The offsets of the first ocurrences of references to groups whose
+numbers are less than 10 are put in cb->small_ref_offset[] (only the first
+occurrence is useful). On 64-bit systems this avoids using more than two parsed
+pattern elements for items such as \3. The offset is used when an error occurs
+because the reference is to a non-existent group.
+
+META_RECURSE is always followed by an offset, for use in error messages.
+
+META_ESCAPE has an ESC_xxx value as its data. For ESC_P and ESC_p, the next
+element contains the 16-bit type and data property values, packed together.
+ESC_g and ESC_k are used only for named references - numerical ones are turned
+into META_RECURSE or META_BACKREF as appropriate. ESC_g and ESC_k are followed
+by a length and an offset into the pattern to specify the name.
+
+The following have one data item that follows in the next vector element:
+
+META_BIGVALUE         Next is a literal >= META_END
+META_OPTIONS          (?i) and friends (data is new option bits)
+META_POSIX            POSIX class item (data identifies the class)
+META_POSIX_NEG        negative POSIX class item (ditto)
+
+The following are followed by a length element, then a number of character code
+values (which should match with the length):
+
+META_MARK             (*MARK:xxxx)
+META_PRUNE_ARG        (*PRUNE:xxx)
+META_SKIP_ARG         (*SKIP:xxxx)
+META_THEN_ARG         (*THEN:xxxx)
+
+The following are followed by a length element, then an offset in the pattern
+that identifies the name:
+
+META_COND_NAME        (?(<name>) or (?('name') or (?(name)
+META_COND_RNAME       (?(R&name)
+META_COND_RNUMBER     (?(Rdigits)
+META_RECURSE_BYNAME   (?&name)
+META_BACKREF_BYNAME   \k'name'
+
+META_COND_RNUMBER is used for names that start with R and continue with digits,
+because this is an ambiguous case. It could be a back reference to a group with
+that name, or it could be a recursion test on a numbered group.
+
+This one is followed by an offset, for use in error messages, then a number:
+
+META_COND_NUMBER       (?([+-]digits)
+
+The following is followed just by an offset, for use in error messages:
+
+META_COND_DEFINE      (?(DEFINE)
+
+The following are also followed just by an offset, but also the lower 16 bits
+of the main word contain the length of the first branch of the lookbehind
+group; this is used when generating OP_REVERSE for that branch.
+
+META_LOOKBEHIND       (?<=
+META_LOOKBEHINDNOT    (?<!
+
+The following are followed by two elements, the minimum and maximum. Repeat
+values are limited to 65535 (MAX_REPEAT). A maximum value of "unlimited" is
+represented by UNLIMITED_REPEAT, which is bigger than MAX_REPEAT:
+
+META_MINMAX           {n,m}  repeat
+META_MINMAX_PLUS      {n,m}+ repeat
+META_MINMAX_QUERY     {n,m}? repeat
+
+This one is followed by three elements. The first is 0 for '>' and 1 for '>=';
+the next two are the major and minor numbers:
+
+META_COND_VERSION     (?(VERSION<op>x.y)
+
+Callouts are converted into one of two items:
+
+META_CALLOUT_NUMBER   (?C with numerical argument
+META_CALLOUT_STRING   (?C with string argument
+
+In both cases, the next two elements contain the offset and length of the next
+item in the pattern. Then there is either one callout number, or a length and
+an offset for the string argument. The length includes both delimiters.
+
+
+Traditional matching function
+-----------------------------
+
+The "traditional", and original, matching function is called pcre2_match(), and
+it implements an NFA algorithm, similar to the original Henry Spencer algorithm
+and the way that Perl works. This is not surprising, since it is intended to be
+as compatible with Perl as possible. This is the function most users of PCRE2
+will use most of the time. If PCRE2 is compiled with just-in-time (JIT)
+support, and studying a compiled pattern with JIT is successful, the JIT code
+is run instead of the normal pcre2_match() code, but the result is the same.
+
+
+Supplementary matching function
+-------------------------------
+
+There is also a supplementary matching function called pcre2_dfa_match(). This
+implements a DFA matching algorithm that searches simultaneously for all
+possible matches that start at one point in the subject string. (Going back to
+my roots: see Historical Note 1 above.) This function intreprets the same
+compiled pattern data as pcre2_match(); however, not all the facilities are
+available, and those that are do not always work in quite the same way. See the
+user documentation for details.
+
+The algorithm that is used for pcre2_dfa_match() is not a traditional FSM,
+because it may have a number of states active at one time. More work would be
+needed at compile time to produce a traditional FSM where only one state is
+ever active at once. I believe some other regex matchers work this way. JIT
+support is not available for this kind of matching.
+
+
+Changeable options
+------------------
+
+The /i, /m, or /s options (PCRE2_CASELESS, PCRE2_MULTILINE, PCRE2_DOTALL, and
+others) may be changed in the middle of patterns by items such as (?i). Their
+processing is handled entirely at compile time by generating different opcodes
+for the different settings. The runtime functions do not need to keep track of
+an options state.
+
+PCRE2_DUPNAMES, PCRE2_EXTENDED, PCRE2_EXTENDED_MORE, and PCRE2_NO_AUTO_CAPTURE
+are tracked and processed during the parsing pre-pass. The others are handled
+from META_OPTIONS items during the main compile phase.
+
+
+Format of compiled patterns
+---------------------------
+
+The compiled form of a pattern is a vector of unsigned code units (bytes in
+8-bit mode, shorts in 16-bit mode, 32-bit words in 32-bit mode), containing
+items of variable length. The first code unit in an item contains an opcode,
+and the length of the item is either implicit in the opcode or contained in the
+data that follows it.
+
+In many cases listed below, LINK_SIZE data values are specified for offsets
+within the compiled pattern. LINK_SIZE always specifies a number of bytes. The
+default value for LINK_SIZE is 2, except for the 32-bit library, where it can
+only be 4. The 8-bit library can be compiled to used 3-byte or 4-byte values,
+and the 16-bit library can be compiled to use 4-byte values, though this
+impairs performance. Specifing a LINK_SIZE larger than 2 for these libraries is
+necessary only when patterns whose compiled length is greater than 64K code
+units are going to be processed. When a LINK_SIZE value uses more than one code
+unit, the most significant unit is first.
+
+In this description, we assume the "normal" compilation options. Data values
+that are counts (e.g. quantifiers) are always two bytes long in 8-bit mode
+(most significant byte first), and one code unit in 16-bit and 32-bit modes.
+
+
+Opcodes with no following data
+------------------------------
+
+These items are all just one unit long
+
+  OP_END                 end of pattern
+  OP_ANY                 match any one character other than newline
+  OP_ALLANY              match any one character, including newline
+  OP_ANYBYTE             match any single code unit, even in UTF-8/16 mode
+  OP_SOD                 match start of data: \A
+  OP_SOM,                start of match (subject + offset): \G
+  OP_SET_SOM,            set start of match (\K)
+  OP_CIRC                ^ (start of data)
+  OP_CIRCM               ^ multiline mode (start of data or after newline)
+  OP_NOT_WORD_BOUNDARY   \W
+  OP_WORD_BOUNDARY       \w
+  OP_NOT_DIGIT           \D
+  OP_DIGIT               \d
+  OP_NOT_HSPACE          \H
+  OP_HSPACE              \h
+  OP_NOT_WHITESPACE      \S
+  OP_WHITESPACE          \s
+  OP_NOT_VSPACE          \V
+  OP_VSPACE              \v
+  OP_NOT_WORDCHAR        \W
+  OP_WORDCHAR            \w
+  OP_EODN                match end of data or newline at end: \Z
+  OP_EOD                 match end of data: \z
+  OP_DOLL                $ (end of data, or before final newline)
+  OP_DOLLM               $ multiline mode (end of data or before newline)
+  OP_EXTUNI              match an extended Unicode grapheme cluster
+  OP_ANYNL               match any Unicode newline sequence
+
+  OP_ASSERT_ACCEPT       )
+  OP_ACCEPT              ) These are Perl 5.10's "backtracking control
+  OP_COMMIT              ) verbs". If OP_ACCEPT is inside capturing
+  OP_FAIL                ) parentheses, it may be preceded by one or more
+  OP_PRUNE               ) OP_CLOSE, each followed by a number that
+  OP_SKIP                ) indicates which parentheses must be closed.
+  OP_THEN                )
+
+OP_ASSERT_ACCEPT is used when (*ACCEPT) is encountered within an assertion.
+This ends the assertion, not the entire pattern match. The assertion (?!) is
+always optimized to OP_FAIL.
+
+OP_ALLANY is used for '.' when PCRE2_DOTALL is set. It is also used for \C in
+non-UTF modes and in UTF-32 mode (since one code unit still equals one
+character). Another use is for [^] when empty classes are permitted
+(PCRE2_ALLOW_EMPTY_CLASS is set).
+
+
+Backtracking control verbs with optional data
+---------------------------------------------
+
+(*THEN) without an argument generates the opcode OP_THEN and no following data.
+OP_MARK is followed by the mark name, preceded by a length in one code unit,
+and followed by a binary zero. For (*PRUNE), (*SKIP), and (*THEN) with
+arguments, the opcodes OP_PRUNE_ARG, OP_SKIP_ARG, and OP_THEN_ARG are used,
+with the name following in the same format as OP_MARK.
+
+
+Matching literal characters
+---------------------------
+
+The OP_CHAR opcode is followed by a single character that is to be matched
+casefully. For caseless matching of characters that have at most two
+case-equivalent code points, OP_CHARI is used. In UTF-8 or UTF-16 modes, the
+character may be more than one code unit long. In UTF-32 mode, characters are
+always exactly one code unit long.
+
+If there is only one character in a character class, OP_CHAR or OP_CHARI is
+used for a positive class, and OP_NOT or OP_NOTI for a negative one (that is,
+for something like [^a]).
+
+Caseless matching (positive or negative) of characters that have more than two
+case-equivalent code points (which is possible only in UTF mode) is handled by
+compiling a Unicode property item (see below), with the pseudo-property
+PT_CLIST. The value of this property is an offset in a vector called
+"ucd_caseless_sets" which identifies the start of a short list of equivalent
+characters, terminated by the value NOTACHAR (0xffffffff).
+
+
+Repeating single characters
+---------------------------
+
+The common repeats (*, +, ?), when applied to a single character, use the
+following opcodes, which come in caseful and caseless versions:
+
+  Caseful         Caseless
+  OP_STAR         OP_STARI
+  OP_MINSTAR      OP_MINSTARI
+  OP_POSSTAR      OP_POSSTARI
+  OP_PLUS         OP_PLUSI
+  OP_MINPLUS      OP_MINPLUSI
+  OP_POSPLUS      OP_POSPLUSI
+  OP_QUERY        OP_QUERYI
+  OP_MINQUERY     OP_MINQUERYI
+  OP_POSQUERY     OP_POSQUERYI
+
+Each opcode is followed by the character that is to be repeated. In ASCII or
+UTF-32 modes, these are two-code-unit items; in UTF-8 or UTF-16 modes, the
+length is variable. Those with "MIN" in their names are the minimizing
+versions. Those with "POS" in their names are possessive versions. Other kinds
+of repeat make use of these opcodes:
+
+  Caseful         Caseless
+  OP_UPTO         OP_UPTOI
+  OP_MINUPTO      OP_MINUPTOI
+  OP_POSUPTO      OP_POSUPTOI
+  OP_EXACT        OP_EXACTI
+
+Each of these is followed by a count and then the repeated character. The count
+is two bytes long in 8-bit mode (most significant byte first), or one code unit
+in 16-bit and 32-bit modes.
+
+OP_UPTO matches from 0 to the given number. A repeat with a non-zero minimum
+and a fixed maximum is coded as an OP_EXACT followed by an OP_UPTO (or
+OP_MINUPTO or OPT_POSUPTO).
+
+Another set of matching repeating opcodes (called OP_NOTSTAR, OP_NOTSTARI,
+etc.) are used for repeated, negated, single-character classes such as [^a]*.
+The normal single-character opcodes (OP_STAR, etc.) are used for repeated
+positive single-character classes.
+
+
+Repeating character types
+-------------------------
+
+Repeats of things like \d are done exactly as for single characters, except
+that instead of a character, the opcode for the type (e.g. OP_DIGIT) is stored
+in the next code unit. The opcodes are:
+
+  OP_TYPESTAR
+  OP_TYPEMINSTAR
+  OP_TYPEPOSSTAR
+  OP_TYPEPLUS
+  OP_TYPEMINPLUS
+  OP_TYPEPOSPLUS
+  OP_TYPEQUERY
+  OP_TYPEMINQUERY
+  OP_TYPEPOSQUERY
+  OP_TYPEUPTO
+  OP_TYPEMINUPTO
+  OP_TYPEPOSUPTO
+  OP_TYPEEXACT
+
+
+Match by Unicode property
+-------------------------
+
+OP_PROP and OP_NOTPROP are used for positive and negative matches of a
+character by testing its Unicode property (the \p and \P escape sequences).
+Each is followed by two code units that encode the desired property as a type
+and a value. The types are a set of #defines of the form PT_xxx, and the values
+are enumerations of the form ucp_xx, defined in the pcre2_ucp.h source file.
+The value is relevant only for PT_GC (General Category), PT_PC (Particular
+Category), PT_SC (Script), and the pseudo-property PT_CLIST, which is used to
+identify a list of case-equivalent characters when there are three or more.
+
+Repeats of these items use the OP_TYPESTAR etc. set of opcodes, followed by
+three code units: OP_PROP or OP_NOTPROP, and then the desired property type and
+value.
+
+
+Character classes
+-----------------
+
+If there is only one character in a class, OP_CHAR or OP_CHARI is used for a
+positive class, and OP_NOT or OP_NOTI for a negative one (that is, for
+something like [^a]), except when caselessly matching a character that has more
+than two case-equivalent code points (which can happen only in UTF mode). In
+this case a Unicode property item is used, as described above in "Matching
+literal characters".
+
+A set of repeating opcodes (called OP_NOTSTAR etc.) are used for repeated,
+negated, single-character classes. The normal single-character opcodes
+(OP_STAR, etc.) are used for repeated positive single-character classes.
+
+When there is more than one character in a class, and all the code points are
+less than 256, OP_CLASS is used for a positive class, and OP_NCLASS for a
+negative one. In either case, the opcode is followed by a 32-byte (16-short,
+8-word) bit map containing a 1 bit for every character that is acceptable. The
+bits are counted from the least significant end of each unit. In caseless mode,
+bits for both cases are set.
+
+The reason for having both OP_CLASS and OP_NCLASS is so that, in UTF-8 and
+16-bit and 32-bit modes, subject characters with values greater than 255 can be
+handled correctly. For OP_CLASS they do not match, whereas for OP_NCLASS they
+do.
+
+For classes containing characters with values greater than 255 or that contain
+\p or \P, OP_XCLASS is used. It optionally uses a bit map if any acceptable
+code points are less than 256, followed by a list of pairs (for a range) and/or
+single characters and/or properties. In caseless mode, all equivalent
+characters are explicitly listed.
+
+OP_XCLASS is followed by a LINK_SIZE value containing the total length of the
+opcode and its data. This is followed by a code unit containing flag bits:
+XCL_NOT indicates that this is a negative class, and XCL_MAP indicates that a
+bit map is present. There follows the bit map, if XCL_MAP is set, and then a
+sequence of items coded as follows:
+
+  XCL_END      marks the end of the list
+  XCL_SINGLE   one character follows
+  XCL_RANGE    two characters follow
+  XCL_PROP     a Unicode property (type, value) follows
+  XCL_NOTPROP  a Unicode property (type, value) follows
+
+If a range starts with a code point less than 256 and ends with one greater
+than 255, it is split into two ranges, with characters less than 256 being
+indicated in the bit map, and the rest with XCL_RANGE.
+
+When XCL_NOT is set, the bit map, if present, contains bits for characters that
+are allowed (exactly as for OP_NCLASS), but the list of items that follow it
+specifies characters and properties that are not allowed.
+
+
+Back references
+---------------
+
+OP_REF (caseful) or OP_REFI (caseless) is followed by a count containing the
+reference number when the reference is to a unique capturing group (either by
+number or by name). When named groups are used, there may be more than one
+group with the same name. In this case, a reference to such a group by name
+generates OP_DNREF or OP_DNREFI. These are followed by two counts: the index
+(not the byte offset) in the group name table of the first entry for the
+required name, followed by the number of groups with the same name. The
+matching code can then search for the first one that is set.
+
+
+Repeating character classes and back references
+-----------------------------------------------
+
+Single-character classes are handled specially (see above). This section
+applies to other classes and also to back references. In both cases, the repeat
+information follows the base item. The matching code looks at the following
+opcode to see if it is one of these:
+
+  OP_CRSTAR
+  OP_CRMINSTAR
+  OP_CRPOSSTAR
+  OP_CRPLUS
+  OP_CRMINPLUS
+  OP_CRPOSPLUS
+  OP_CRQUERY
+  OP_CRMINQUERY
+  OP_CRPOSQUERY
+  OP_CRRANGE
+  OP_CRMINRANGE
+  OP_CRPOSRANGE
+
+All but the last three are single-code-unit items, with no data. The range
+opcodes are followed by the minimum and maximum repeat counts.
+
+
+Brackets and alternation
+------------------------
+
+A pair of non-capturing round brackets is wrapped round each expression at
+compile time, so alternation always happens in the context of brackets.
+
+[Note for North Americans: "bracket" to some English speakers, including
+myself, can be round, square, curly, or pointy. Hence this usage rather than
+"parentheses".]
+
+Non-capturing brackets use the opcode OP_BRA, capturing brackets use OP_CBRA. A
+bracket opcode is followed by a LINK_SIZE value which gives the offset to the
+next alternative OP_ALT or, if there aren't any branches, to the terminating
+opcode. Each OP_ALT is followed by a LINK_SIZE value giving the offset to the
+next one, or to the final opcode. For capturing brackets, the bracket number is
+a count that immediately follows the offset.
+
+There are several opcodes that mark the end of a subpattern group. OP_KET is
+used for subpatterns that do not repeat indefinitely, OP_KETRMIN and
+OP_KETRMAX are used for indefinite repetitions, minimally or maximally
+respectively, and OP_KETRPOS for possessive repetitions (see below for more 
+details). All four are followed by a LINK_SIZE value giving (as a positive
+number) the offset back to the matching bracket opcode.
+
+If a subpattern is quantified such that it is permitted to match zero times, it
+is preceded by one of OP_BRAZERO, OP_BRAMINZERO, or OP_SKIPZERO. These are
+single-unit opcodes that tell the matcher that skipping the following
+subpattern entirely is a valid match. In the case of the first two, not
+skipping the pattern is also valid (greedy and non-greedy). The third is used
+when a pattern has the quantifier {0,0}. It cannot be entirely discarded,
+because it may be called as a subroutine from elsewhere in the pattern.
+
+A subpattern with an indefinite maximum repetition is replicated in the
+compiled data its minimum number of times (or once with OP_BRAZERO if the
+minimum is zero), with the final copy terminating with OP_KETRMIN or OP_KETRMAX
+as appropriate.
+
+A subpattern with a bounded maximum repetition is replicated in a nested
+fashion up to the maximum number of times, with OP_BRAZERO or OP_BRAMINZERO
+before each replication after the minimum, so that, for example, (abc){2,5} is
+compiled as (abc)(abc)((abc)((abc)(abc)?)?)?, except that each bracketed group
+has the same number.
+
+When a repeated subpattern has an unbounded upper limit, it is checked to see
+whether it could match an empty string. If this is the case, the opcode in the
+final replication is changed to OP_SBRA or OP_SCBRA. This tells the matcher
+that it needs to check for matching an empty string when it hits OP_KETRMIN or
+OP_KETRMAX, and if so, to break the loop.
+
+
+Possessive brackets
+-------------------
+
+When a repeated group (capturing or non-capturing) is marked as possessive by
+the "+" notation, e.g. (abc)++, different opcodes are used. Their names all
+have POS on the end, e.g. OP_BRAPOS instead of OP_BRA and OP_SCBRAPOS instead
+of OP_SCBRA. The end of such a group is marked by OP_KETRPOS. If the minimum
+repetition is zero, the group is preceded by OP_BRAPOSZERO.
+
+
+Once-only (atomic) groups
+-------------------------
+
+These are just like other subpatterns, but they start with the opcode OP_ONCE.
+The check for matching an empty string in an unbounded repeat is handled
+entirely at runtime, so there is just this one opcode for atomic groups.
+
+
+Assertions
+----------
+
+Forward assertions are also just like other subpatterns, but starting with one
+of the opcodes OP_ASSERT or OP_ASSERT_NOT. Backward assertions use the opcodes
+OP_ASSERTBACK and OP_ASSERTBACK_NOT, and the first opcode inside the assertion
+is OP_REVERSE, followed by a count of the number of characters to move back the
+pointer in the subject string. In ASCII or UTF-32 mode, the count is also the
+number of code units, but in UTF-8/16 mode each character may occupy more than
+one code unit. A separate count is present in each alternative of a lookbehind
+assertion, allowing them to have different (but fixed) lengths.
+
+
+Conditional subpatterns
+-----------------------
+
+These are like other subpatterns, but they start with the opcode OP_COND, or
+OP_SCOND for one that might match an empty string in an unbounded repeat.
+
+If the condition is a back reference, this is stored at the start of the
+subpattern using the opcode OP_CREF followed by a count containing the
+reference number, provided that the reference is to a unique capturing group.
+If the reference was by name and there is more than one group with that name,
+OP_DNCREF is used instead. It is followed by two counts: the index in the group
+names table, and the number of groups with the same name. The allows the
+matcher to check if any group with the given name is set.
+
+If the condition is "in recursion" (coded as "(?(R)"), or "in recursion of
+group x" (coded as "(?(Rx)"), the group number is stored at the start of the
+subpattern using the opcode OP_RREF (with a value of RREF_ANY (0xffff) for "the
+whole pattern") or OP_DNRREF (with data as for OP_DNCREF).
+
+For a DEFINE condition, OP_FALSE is used (with no associated data). During
+compilation, however, a DEFINE condition is coded as OP_DEFINE so that, when
+the conditional group is complete, there can be a check to ensure that it
+contains only one top-level branch. Once this has happened, the opcode is
+changed to OP_FALSE, so the matcher never sees OP_DEFINE.
+
+There is a special PCRE2-specific condition of the form (VERSION[>]=x.y), which
+tests the PCRE2 version number. This compiles into one of the opcodes OP_TRUE
+or OP_FALSE.
+
+If a condition is not a back reference, recursion test, DEFINE, or VERSION, it
+must start with a parenthesized assertion, whose opcode normally immediately
+follows OP_COND or OP_SCOND. However, if automatic callouts are enabled, a
+callout is inserted immediately before the assertion. It is also possible to
+insert a manual callout at this point. Only assertion conditions may have
+callouts preceding the condition.
+
+A condition that is the negative assertion (?!) is optimized to OP_FAIL in all
+parts of the pattern, so this is another opcode that may appear as a condition.
+It is treated the same as OP_FALSE.
+
+
+Recursion
+---------
+
+Recursion either matches the current pattern, or some subexpression. The opcode
+OP_RECURSE is followed by a LINK_SIZE value that is the offset to the starting
+bracket from the start of the whole pattern. OP_RECURSE is also used for
+"subroutine" calls, even though they are not strictly a recursion. Up till
+release 10.30 recursions were treated as atomic groups, making them
+incompatible with Perl (but PCRE had then well before Perl did). From 10.30,
+backtracking into recursions is supported.
+
+Repeated recursions used to be wrapped inside OP_ONCE brackets, which not only
+forced no backtracking, but also allowed repetition to be handled as for other
+bracketed groups. From 10.30 onwards, repeated recursions are duplicated for
+their minimum repetitions, and then wrapped in non-capturing brackets for the
+remainder. For example, (?1){3} is treated as (?1)(?1)(?1), and (?1){2,4} is
+treated as (?1)(?1)(?:(?1)){0,2}.
+
+
+Callouts
+--------
+
+A callout may have either a numerical argument or a string argument. These use
+OP_CALLOUT or OP_CALLOUT_STR, respectively. In each case these are followed by
+two LINK_SIZE values giving the offset in the pattern string to the start of
+the following item, and another count giving the length of this item. These
+values make it possible for pcre2test to output useful tracing information
+using callouts.
+
+In the case of a numeric callout, after these two values there is a single code
+unit containing the callout number, in the range 0-255, with 255 being used for
+callouts that are automatically inserted as a result of the PCRE2_AUTO_CALLOUT
+option. Thus, this opcode item is of fixed length:
+
+  [OP_CALLOUT] [PATTERN_OFFSET] [PATTERN_LENGTH] [NUMBER]
+
+For callouts with string arguments, OP_CALLOUT_STR has three more data items:
+a LINK_SIZE value giving the complete length of the entire opcode item, a
+LINK_SIZE item containing the offset within the pattern string to the start of
+the string argument, and the string itself, preceded by its starting delimiter
+and followed by a binary zero. When a callout function is called, a pointer to
+the actual string is passed, but the delimiter can be accessed as string[-1] if
+the application needs it. In the 8-bit library, the callout in /X(?C'abc')Y/ is
+compiled as the following bytes (decimal numbers represent binary values):
+
+  [OP_CALLOUT_STR]  [0] [10]  [0] [1]  [0] [14]  [0] [5] ['] [a] [b] [c] [0]
+                    --------  -------  --------  -------
+                       |         |        |         |
+                       ------- LINK_SIZE items ------
+
+Opcode table checking
+---------------------
+
+The last opcode that is defined in pcre2_internal.h is OP_TABLE_LENGTH. This is
+not a real opcode, but is used to check at compile time that tables indexed by
+opcode are the correct length, in order to catch updating errors.

+without warranty of any kind.
+
+Basic Installation
+==================
+
+   Briefly, the shell command './configure && make && make install'
+should configure, build, and install this package.  The following
+more-detailed instructions are generic; see the 'README' file for
+instructions specific to this package.  Some packages provide this
+'INSTALL' file but do not implement all of the features documented
+below.  The lack of an optional feature in a given package is not
+necessarily a bug.  More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+   The 'configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a 'Makefile' in each directory of the package.
+It may also create one or more '.h' files containing system-dependent
+definitions.  Finally, it creates a shell script 'config.status' that
+you can run in the future to recreate the current configuration, and a
+file 'config.log' containing compiler output (useful mainly for
+debugging 'configure').
+
+   It can also use an optional file (typically called 'config.cache' and
+enabled with '--cache-file=config.cache' or simply '-C') that saves the
+results of its tests to speed up reconfiguring.  Caching is disabled by
+default to prevent problems with accidental use of stale cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how 'configure' could check whether to do them, and mail
+diffs or instructions to the address given in the 'README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point 'config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file 'configure.ac' (or 'configure.in') is used to create
+'configure' by a program called 'autoconf'.  You need 'configure.ac' if
+you want to change it or regenerate 'configure' using a newer version of
+'autoconf'.
+
+   The simplest way to compile this package is:
+
+  1. 'cd' to the directory containing the package's source code and type
+     './configure' to configure the package for your system.
+
+     Running 'configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type 'make' to compile the package.
+
+  3. Optionally, type 'make check' to run any self-tests that come with
+     the package, generally using the just-built uninstalled binaries.
+
+  4. Type 'make install' to install the programs and any data files and
+     documentation.  When installing into a prefix owned by root, it is
+     recommended that the package be configured and built as a regular
+     user, and only the 'make install' phase executed with root
+     privileges.
+
+  5. Optionally, type 'make installcheck' to repeat any self-tests, but
+     this time using the binaries in their final installed location.
+     This target does not install anything.  Running this target as a
+     regular user, particularly if the prior 'make install' required
+     root privileges, verifies that the installation completed
+     correctly.
+
+  6. You can remove the program binaries and object files from the
+     source code directory by typing 'make clean'.  To also remove the
+     files that 'configure' created (so you can compile the package for
+     a different kind of computer), type 'make distclean'.  There is
+     also a 'make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+  7. Often, you can also type 'make uninstall' to remove the installed
+     files again.  In practice, not all packages have tested that
+     uninstallation works correctly, even though it is required by the
+     GNU Coding Standards.
+
+  8. Some packages, particularly those that use Automake, provide 'make
+     distcheck', which can by used by developers to test that all other
+     targets like 'make install' and 'make uninstall' work correctly.
+     This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+   Some systems require unusual options for compilation or linking that
+the 'configure' script does not know about.  Run './configure --help'
+for details on some of the pertinent environment variables.
+
+   You can give 'configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here is
+an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+   You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU 'make'.  'cd' to the
+directory where you want the object files and executables to go and run
+the 'configure' script.  'configure' automatically checks for the source
+code in the directory that 'configure' is in and in '..'.  This is known
+as a "VPATH" build.
+
+   With a non-GNU 'make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use 'make distclean' before
+reconfiguring for another architecture.
+
+   On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple '-arch' options to the
+compiler but only a single '-arch' option to the preprocessor.  Like
+this:
+
+     ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+                 CPP="gcc -E" CXXCPP="g++ -E"
+
+   This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the 'lipo' tool if you have problems.
+
+Installation Names
+==================
+
+   By default, 'make install' installs the package's commands under
+'/usr/local/bin', include files under '/usr/local/include', etc.  You
+can specify an installation prefix other than '/usr/local' by giving
+'configure' the option '--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like '--bindir=DIR' to specify different values for particular
+kinds of files.  Run 'configure --help' for a list of the directories
+you can set and what kinds of files go in them.  In general, the default
+for these options is expressed in terms of '${prefix}', so that
+specifying just '--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+   The most portable way to affect installation locations is to pass the
+correct locations to 'configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+'make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+   The first method involves providing an override variable for each
+affected directory.  For example, 'make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+'${prefix}'.  Any directories that were specified during 'configure',
+but not in terms of '${prefix}', must each be overridden at install time
+for the entire installation to be relocated.  The approach of makefile
+variable overrides for each directory variable is required by the GNU
+Coding Standards, and ideally causes no recompilation.  However, some
+platforms have known limitations with the semantics of shared libraries
+that end up requiring recompilation when using this method, particularly
+noticeable in packages that use GNU Libtool.
+
+   The second method involves providing the 'DESTDIR' variable.  For
+example, 'make install DESTDIR=/alternate/directory' will prepend
+'/alternate/directory' before all installation names.  The approach of
+'DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters.  On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of '${prefix}'
+at 'configure' time.
+
+Optional Features
+=================
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving 'configure' the
+option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
+
+   Some packages pay attention to '--enable-FEATURE' options to
+'configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to '--with-PACKAGE' options, where PACKAGE
+is something like 'gnu-as' or 'x' (for the X Window System).  The
+'README' should mention any '--enable-' and '--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, 'configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the 'configure' options '--x-includes=DIR' and
+'--x-libraries=DIR' to specify their locations.
+
+   Some packages offer the ability to configure how verbose the
+execution of 'make' will be.  For these packages, running './configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with 'make V=1'; while running './configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with 'make V=0'.
+
+Particular systems
+==================
+
+   On HP-UX, the default C compiler is not ANSI C compatible.  If GNU CC
+is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+     ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+   HP-UX 'make' updates targets which have the same time stamps as their
+prerequisites, which makes it generally unusable when shipped generated
+files such as 'configure' are involved.  Use GNU 'make' instead.
+
+   On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its '<wchar.h>' header file.  The option '-nodtk' can be used as a
+workaround.  If GNU CC is not installed, it is therefore recommended to
+try
+
+     ./configure CC="cc"
+
+and if that doesn't work, try
+
+     ./configure CC="cc -nodtk"
+
+   On Solaris, don't put '/usr/ucb' early in your 'PATH'.  This
+directory contains several dysfunctional programs; working variants of
+these programs are available in '/usr/bin'.  So, if you need '/usr/ucb'
+in your 'PATH', put it _after_ '/usr/bin'.
+
+   On Haiku, software installed for all users goes in '/boot/common',
+not '/usr/local'.  It is recommended to use the following options:
+
+     ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+   There may be some features 'configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on.  Usually, assuming the package is built to be run on the
+_same_ architectures, 'configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+'--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as 'sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS
+     KERNEL-OS
+
+   See the file 'config.sub' for the possible values of each field.  If
+'config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option '--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with '--host=TYPE'.
+
+Sharing Defaults
+================
+
+   If you want to set default values for 'configure' scripts to share,
+you can create a site shell script called 'config.site' that gives
+default values for variables like 'CC', 'cache_file', and 'prefix'.
+'configure' looks for 'PREFIX/share/config.site' if it exists, then
+'PREFIX/etc/config.site' if it exists.  Or, you can set the
+'CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all 'configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+   Variables not defined in a site shell script can be set in the
+environment passed to 'configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the 'configure' command line, using 'VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified 'gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
+Autoconf limitation.  Until the limitation is lifted, you can use this
+workaround:
+
+     CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+'configure' Invocation
+======================
+
+   'configure' recognizes the following options to control how it
+operates.
+
+'--help'
+'-h'
+     Print a summary of all of the options to 'configure', and exit.
+
+'--help=short'
+'--help=recursive'
+     Print a summary of the options unique to this package's
+     'configure', and exit.  The 'short' variant lists options used only
+     in the top level, while the 'recursive' variant lists options also
+     present in any nested packages.
+
+'--version'
+'-V'
+     Print the version of Autoconf used to generate the 'configure'
+     script, and exit.
+
+'--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally 'config.cache'.  FILE defaults to '/dev/null' to
+     disable caching.
+
+'--config-cache'
+'-C'
+     Alias for '--cache-file=config.cache'.
+
+'--quiet'
+'--silent'
+'-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to '/dev/null' (any error
+     messages will still be shown).
+
+'--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     'configure' can determine that directory automatically.
+
+'--prefix=DIR'
+     Use DIR as the installation prefix.  *note Installation Names:: for
+     more details, including other options available for fine-tuning the
+     installation locations.
+
+'--no-create'
+'-n'
+     Run the configure checks, but stop before creating any output
+     files.
+
+'configure' also accepts some other, not widely useful, options.  Run
+'configure --help' for more details.

+News about PCRE2 releases
+-------------------------
+
+Version 10.31 12-February-2018
+------------------------------
+
+This is mainly a bugfix and tidying release (see ChangeLog for full details).
+However, there are some minor enhancements.
+
+1. New pcre2_config() options: PCRE2_CONFIG_NEVER_BACKSLASH_C and
+PCRE2_CONFIG_COMPILED_WIDTHS.
+
+2. New pcre2_pattern_info() option PCRE2_INFO_EXTRAOPTIONS to retrieve the
+extra compile time options.
+
+3. There are now public names for all the pcre2_compile() error numbers.
+
+4. Added PCRE2_CALLOUT_STARTMATCH and PCRE2_CALLOUT_BACKTRACK bits to a new
+field callout_flags in callout blocks.
+
+
+Version 10.30 14-August-2017
+----------------------------
+
+The full list of changes that includes bugfixes and tidies is, as always, in
+ChangeLog. These are the most important new features:
+
+1. The main interpreter, pcre2_match(), has been refactored into a new version
+that does not use recursive function calls (and therefore the system stack) for
+remembering backtracking positions. This makes --disable-stack-for-recursion a
+NOOP. The new implementation allows backtracking into recursive group calls in
+patterns, making it more compatible with Perl, and also fixes some other
+previously hard-to-do issues. For patterns that have a lot of backtracking, the
+heap is now used, and there is explicit limit on the amount, settable by
+pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). The "recursion limit" is retained,
+but is renamed as "depth limit" (though the old names remain for
+compatibility).
+
+There is also a change in the way callouts from pcre2_match() are handled. The
+offset_vector field in the callout block is no longer a pointer to the
+actual ovector that was passed to the matching function in the match data
+block. Instead it points to an internal ovector of a size large enough to hold
+all possible captured substrings in the pattern.
+
+2. The new option PCRE2_ENDANCHORED insists that a pattern match must end at
+the end of the subject.
+
+3. The new option PCRE2_EXTENDED_MORE implements Perl's /xx feature, and
+pcre2test is upgraded to support it. Setting within the pattern by (?xx) is
+also supported.
+
+4. (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
+
+5. Additional compile options in the compile context are now available, and the
+first two are: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
+PCRE2_EXTRA_BAD_ESCAPE_IS LITERAL.
+
+6. The newline type PCRE2_NEWLINE_NUL is now available.
+
+7. The match limit value now also applies to pcre2_dfa_match() as there are
+patterns that can use up a lot of resources without necessarily recursing very
+deeply.
+
+8. The option REG_PEND (a GNU extension) is now available for the POSIX
+wrapper. Also there is a new option PCRE2_LITERAL which is used to support
+REG_NOSPEC.
+
+9. PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are implemented for the
+benefit of pcre2grep, and pcre2grep's -F, -w, and -x options are re-implemented
+using PCRE2_LITERAL, PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This
+is tidier and also fixes some bugs.
+
+10. The Unicode tables are upgraded from Unicode 8.0.0 to Unicode 10.0.0.
+
+11. There are some experimental functions for converting foreign patterns
+(globs and POSIX patterns) into PCRE2 patterns.
+
+
+Version 10.23 14-February-2017
+------------------------------
+
+1. ChangeLog has the details of a lot of bug fixes and tidies.
+
+2. There has been a major re-factoring of the pcre2_compile.c file. Most syntax
+checking is now done in the pre-pass that identifies capturing groups. This has
+reduced the amount of duplication and made the code tidier. While doing this,
+some minor bugs and Perl incompatibilities were fixed (see ChangeLog for
+details.)
+
+3. Back references are now permitted in lookbehind assertions when there are
+no duplicated group numbers (that is, (?| has not been used), and, if the
+reference is by name, there is only one group of that name. The referenced
+group must, of course be of fixed length.
+
+4. \g{+<number>} (e.g. \g{+2} ) is now supported. It is a "forward back
+reference" and can be useful in repetitions (compare \g{-<number>} ). Perl does
+not recognize this syntax.
+
+5. pcre2grep now automatically expands its buffer up to a maximum set by
+--max-buffer-size.
+
+6. The -t option (grand total) has been added to pcre2grep.
+
+7. A new function called pcre2_code_copy_with_tables() exists to copy a
+compiled pattern along with a private copy of the character tables that is
+uses.
+
+8. A user supplied a number of patches to upgrade pcre2grep under Windows and
+tidy the code.
+
+9. Several updates have been made to pcre2test and test scripts (see
+ChangeLog).
+
+
+Version 10.22 29-July-2016
+--------------------------
+
+1. ChangeLog has the details of a number of bug fixes.
+
+2. The POSIX wrapper function regcomp() did not used to support back references
+and subroutine calls if called with the REG_NOSUB option. It now does.
+
+3. A new function, pcre2_code_copy(), is added, to make a copy of a compiled
+pattern.
+
+4. Support for string callouts is added to pcre2grep.
+
+5. Added the PCRE2_NO_JIT option to pcre2_match().
+
+6. The pcre2_get_error_message() function now returns with a negative error
+code if the error number it is given is unknown.
+
+7. Several updates have been made to pcre2test and test scripts (see
+ChangeLog).
+
+
+Version 10.21 12-January-2016
+-----------------------------
+
+1. Many bugs have been fixed. A large number of them were provoked only by very
+strange pattern input, and were discovered by fuzzers. Some others were
+discovered by code auditing. See ChangeLog for details.
+
+2. The Unicode tables have been updated to Unicode version 8.0.0.
+
+3. For Perl compatibility in EBCDIC environments, ranges such as a-z in a
+class, where both values are literal letters in the same case, omit the
+non-letter EBCDIC code points within the range.
+
+4. There have been a number of enhancements to the pcre2_substitute() function,
+giving more flexibility to replacement facilities. It is now also possible to
+cause the function to return the needed buffer size if the one given is too
+small.
+
+5. The PCRE2_ALT_VERBNAMES option causes the "name" parts of special verbs such
+as (*THEN:name) to be processed for backslashes and to take note of
+PCRE2_EXTENDED.
+
+6. PCRE2_INFO_HASBACKSLASHC makes it possible for a client to find out if a
+pattern uses \C, and --never-backslash-C makes it possible to compile a version
+PCRE2 in which the use of \C is always forbidden.
+
+7. A limit to the length of pattern that can be handled can now be set by
+calling pcre2_set_max_pattern_length().
+
+8. When matching an unanchored pattern, a match can be required to begin within
+a given number of code units after the start of the subject by calling
+pcre2_set_offset_limit().
+
+9. The pcre2test program has been extended to test new facilities, and it can
+now run the tests when LF on its own is not a valid newline sequence.
+
+10. The RunTest script has also been updated to enable more tests to be run.
+
+11. There have been some minor performance enhancements.
+
+
+Version 10.20 30-June-2015
+--------------------------
+
+1. Callouts with string arguments and the pcre2_callout_enumerate() function
+have been implemented.
+
+2. The PCRE2_NEVER_BACKSLASH_C option, which locks out the use of \C, is added.
+
+3. The PCRE2_ALT_CIRCUMFLEX option lets ^ match after a newline at the end of a
+subject in multiline mode.
+
+4. The way named subpatterns are handled has been refactored. The previous
+approach had several bugs.
+
+5. The handling of \c in EBCDIC environments has been changed to conform to the
+perlebcdic document. This is an incompatible change.
+
+6. Bugs have been mended, many of them discovered by fuzzers.
+
+
+Version 10.10 06-March-2015
+---------------------------
+
+1. Serialization and de-serialization functions have been added to the API,
+making it possible to save and restore sets of compiled patterns, though
+restoration must be done in the same environment that was used for compilation.
+
+2. The (*NO_JIT) feature has been added; this makes it possible for a pattern
+creator to specify that JIT is not to be used.
+
+3. A number of bugs have been fixed. In particular, bugs that caused building
+on Windows using CMake to fail have been mended.
+
+
+Version 10.00 05-January-2015
+-----------------------------
+
+Version 10.00 is the first release of PCRE2, a revised API for the PCRE
+library. Changes prior to 10.00 are logged in the ChangeLog file for the old
+API, up to item 20 for release 8.36. New programs are recommended to use the
+new library. Programs that use the original (PCRE1) API will need changing
+before linking with the new library.

+Building PCRE2 without using autotools
+--------------------------------------

+  Generic instructions for the PCRE2 C library
+  Stack size in Windows environments
+  Linking programs in Windows environments
+  Calling conventions in Windows environments
+  Comments about Win32 builds
+  Building PCRE2 on Windows with CMake

+
+
+GENERAL
+
+The basic PCRE2 library consists entirely of code written in Standard C, and so
+should compile successfully on any system that has a Standard C compiler and
+library.
+
+The PCRE2 distribution includes a "configure" file for use by the
+configure/make (autotools) build system, as found in many Unix-like
+environments. The README file contains information about the options for
+"configure".
+
+There is also support for CMake, which some users prefer, especially in Windows
+environments, though it can also be run in Unix-like environments. See the
+section entitled "Building PCRE2 on Windows with CMake" below.
+
+Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
+under the names src/config.h.generic and src/pcre2.h.generic. These are
+provided for those who build PCRE2 without using "configure" or CMake. If you
+use "configure" or CMake, the .generic versions are not used.
+
+
+GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
+
+The following are generic instructions for building the PCRE2 C library "by
+hand". If you are going to use CMake, this section does not apply to you; you
+can skip ahead to the CMake section.
+
+ (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
+     macro settings that it contains to whatever is appropriate for your
+     environment. In particular, you can alter the definition of the NEWLINE
+     macro to specify what character(s) you want to be interpreted as line
+     terminators by default.
+
+     When you compile any of the PCRE2 modules, you must specify
+     -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
+     sources.
+
+     An alternative approach is not to edit src/config.h, but to use -D on the
+     compiler command line to make any changes that you need to the
+     configuration options. In this case -DHAVE_CONFIG_H must not be set.
+
+     NOTE: There have been occasions when the way in which certain parameters
+     in src/config.h are used has changed between releases. (In the
+     configure/make world, this is handled automatically.) When upgrading to a
+     new release, you are strongly advised to review src/config.h.generic
+     before re-using what you had previously.
+
+ (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
+
+ (3) EITHER:
+       Copy or rename file src/pcre2_chartables.c.dist as
+       src/pcre2_chartables.c.
+
+     OR:
+       Compile src/dftables.c as a stand-alone program (using -DHAVE_CONFIG_H
+       if you have set up src/config.h), and then run it with the single
+       argument "src/pcre2_chartables.c". This generates a set of standard
+       character tables and writes them to that file. The tables are generated
+       using the default C locale for your system. If you want to use a locale
+       that is specified by LC_xxx environment variables, add the -L option to
+       the dftables command. You must use this method if you are building on a
+       system that uses EBCDIC code.
+
+     The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
+     specify alternative tables at run time.
+
+ (4) For an 8-bit library, compile the following source files from the src
+     directory, setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also
+     set -DHAVE_CONFIG_H if you have set up src/config.h with your
+     configuration, or else use other -D settings to change the configuration
+     as required.
+
+       pcre2_auto_possess.c
+       pcre2_chartables.c
+       pcre2_compile.c
+       pcre2_config.c
+       pcre2_context.c
+       pcre2_convert.c
+       pcre2_dfa_match.c

+       pcre2_ucd.c
+       pcre2_valid_utf.c
+       pcre2_xclass.c
+
+     Make sure that you include -I. in the compiler command (or equivalent for
+     an unusual compiler) so that all included PCRE2 header files are first
+     sought in the src directory under the current directory. Otherwise you run
+     the risk of picking up a previously-installed file from somewhere else.
+
+     Note that you must compile pcre2_jit_compile.c, even if you have not
+     defined SUPPORT_JIT in src/config.h, because when JIT support is not
+     configured, dummy functions are compiled. When JIT support IS configured,
+     pcre2_jit_compile.c #includes other files from the sljit subdirectory,
+     all of whose names begin with "sljit". It also #includes
+     src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
+     these yourself.
+
+     Not also that the pcre2_fuzzsupport.c file contains special code that is
+     useful to those who want to run fuzzing tests on the PCRE2 library. Unless
+     you are doing that, you can ignore it.
+
+ (5) Now link all the compiled code into an object library in whichever form
+     your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
+     If your system has static and shared libraries, you may have to do this
+     once for each type.
+
+ (6) If you want to build a 16-bit library or 32-bit library (as well as, or
+     instead of the 8-bit library) just supply 16 or 32 as the value of
+     -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
+
+ (7) If you want to build the POSIX wrapper functions (which apply only to the
+     8-bit library), ensure that you have the src/pcre2posix.h file and then
+     compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
+     library.
+
+ (8) The pcre2test program can be linked with any combination of the 8-bit,
+     16-bit and 32-bit libraries (depending on what you selected in
+     src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
+     necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
+     appropriate library/ies. If you compiled an 8-bit library, pcre2test also
+     needs the pcre2posix wrapper library.
+
+ (9) Run pcre2test on the testinput files in the testdata directory, and check
+     that the output matches the corresponding testoutput files. There are
+     comments about what each test does in the section entitled "Testing PCRE2"
+     in the README file. If you compiled more than one of the 8-bit, 16-bit and
+     32-bit libraries, you need to run pcre2test with the -16 option to do
+     16-bit tests and with the -32 option to do 32-bit tests.
+
+     Some tests are relevant only when certain build-time options are selected.
+     For example, test 4 is for Unicode support, and will not run if you have
+     built PCRE2 without it. See the comments at the start of each testinput
+     file. If you have a suitable Unix-like shell, the RunTest script will run
+     the appropriate tests for you. The command "RunTest list" will output a
+     list of all the tests.
+
+     Note that the supplied files are in Unix format, with just LF characters
+     as line terminators. You may need to edit them to change this if your
+     system uses a different convention.
+
+(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
+     by running pcre2test with the -jit option. This is done automatically by
+     the RunTest script. You might also like to build and run the freestanding
+     JIT test program, src/pcre2_jit_test.c.
+
+(11) If you want to use the pcre2grep command, compile and link
+     src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
+     need the pcre2posix library). If you have built the PCRE2 library with JIT
+     support by defining SUPPORT_JIT in src/config.h, you can also define
+     SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
+     it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
+     defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
+
+
+STACK SIZE IN WINDOWS ENVIRONMENTS
+
+Prior to release 10.30 the default system stack size of 1Mb in some Windows
+environments caused issues with some tests. This should no longer be the case
+for 10.30 and later releases.
+
+
+LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
+
+If you want to statically link a program against a PCRE2 library in the form of
+a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
+
+
+CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
+
+It is possible to compile programs to use different calling conventions using
+MSVC. Search the web for "calling conventions" for more information. To make it
+easier to change the calling convention for the exported functions in the
+PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
+definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
+not set, it defaults to empty; the default calling convention is then used
+(which is what is wanted most of the time).
+
+
+COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
+
+There are two ways of building PCRE2 using the "configure, make, make install"
+paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
+the same thing; they are completely different from each other. There is also
+support for building using CMake, which some users find a more straightforward
+way of building PCRE2 under Windows.
+
+The MinGW home page (http://www.mingw.org/) says this:
+
+  MinGW: A collection of freely available and freely distributable Windows
+  specific header files and import libraries combined with GNU toolsets that
+  allow one to produce native Windows programs that do not rely on any
+  3rd-party C runtime DLLs.
+
+The Cygwin home page (http://www.cygwin.com/) says this:
+
+  Cygwin is a Linux-like environment for Windows. It consists of two parts:
+
+  . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
+    substantial Linux API functionality
+
+  . A collection of tools which provide Linux look and feel.
+
+On both MinGW and Cygwin, PCRE2 should build correctly using:
+
+  ./configure && make && make install
+
+This should create two libraries called libpcre2-8 and libpcre2-posix. These
+are independent libraries: when you link with libpcre2-posix you must also link
+with libpcre2-8, which contains the basic functions.
+
+Using Cygwin's compiler generates libraries and executables that depend on
+cygwin1.dll. If a library that is generated this way is distributed,
+cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
+licence, this forces not only PCRE2 to be under the GPL, but also the entire
+application. A distributor who wants to keep their own code proprietary must
+purchase an appropriate Cygwin licence.
+
+MinGW has no such restrictions. The MinGW compiler generates a library or
+executable that can run standalone on Windows without any third party dll or
+licensing issues.
+
+But there is more complication:
+
+If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
+to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
+front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
+gcc and MinGW's gcc). So, a user can:
+
+. Build native binaries by using MinGW or by getting Cygwin and using
+  -mno-cygwin.
+
+. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
+  compiler flags.
+
+The test files that are supplied with PCRE2 are in UNIX format, with LF
+characters as line terminators. Unless your PCRE2 library uses a default
+newline option that includes LF as a valid newline, it may be necessary to
+change the line terminators in the test files to get some of the tests to work.
+
+
+BUILDING PCRE2 ON WINDOWS WITH CMAKE
+
+CMake is an alternative configuration facility that can be used instead of
+"configure". CMake creates project files (make files, solution files, etc.)
+tailored to numerous development environments, including Visual Studio,
+Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
+spaces in the names for your CMake installation and your PCRE2 source and build
+directories.
+
+The following instructions were contributed by a PCRE1 user, but they should
+also work for PCRE2. If they are not followed exactly, errors may occur. In the
+event that errors do occur, it is recommended that you delete the CMake cache
+before attempting to repeat the CMake build process. In the CMake GUI, the
+cache can be deleted by selecting "File > Delete Cache".
+
+1.  Install the latest CMake version available from http://www.cmake.org/, and
+    ensure that cmake\bin is on your path.
+
+2.  Unzip (retaining folder structure) the PCRE2 source tree into a source
+    directory such as C:\pcre2. You should ensure your local date and time
+    is not earlier than the file dates in your source dir if the release is
+    very new.
+
+3.  Create a new, empty build directory, preferably a subdirectory of the
+    source dir. For example, C:\pcre2\pcre2-xx\build.
+
+4.  Run cmake-gui from the Shell envirornment of your build tool, for example,
+    Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
+    to start Cmake from the Windows Start menu, as this can lead to errors.
+
+5.  Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
+    build directories, respectively.
+
+6.  Hit the "Configure" button.
+
+7.  Select the particular IDE / build tool that you are using (Visual
+    Studio, MSYS makefiles, MinGW makefiles, etc.)
+
+8.  The GUI will then list several configuration options. This is where
+    you can disable Unicode support or select other PCRE2 optional features.
+
+9.  Hit "Configure" again. The adjacent "Generate" button should now be
+    active.
+
+10. Hit "Generate".
+
+11. The build directory should now contain a usable build system, be it a
+    solution file for Visual Studio, makefiles for MinGW, etc. Exit from
+    cmake-gui and use the generated build system with your compiler or IDE.
+    E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
+    solution, select the desired configuration (Debug, or Release, etc.) and
+    build the ALL_BUILD project.
+
+12. If during configuration with cmake-gui you've elected to build the test
+    programs, you can execute them by building the test project. E.g., for
+    MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
+    most recent build configuration is targeted by the tests. A summary of
+    test results is presented. Complete test output is subsequently
+    available for review in Testing\Temporary under your build dir.
+
+
+TESTING WITH RUNTEST.BAT
+
+If configured with CMake, building the test project ("make test" or building
+ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
+on your configuration options, possibly other test programs) in the build
+directory. The pcre2_test.bat script runs RunTest.bat with correct source and
+exe paths.
+
+For manual testing with RunTest.bat, provided the build dir is a subdirectory
+of the source directory: Open command shell window. Chdir to the location
+of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
+"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
+
+To run only a particular test with RunTest.Bat provide a test number argument.
+
+Otherwise:
+
+1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
+   have been created.
+
+2. Edit RunTest.bat to indentify the full or relative location of
+   the pcre2 source (wherein which the testdata folder resides), e.g.:
+
+   set srcdir=C:\pcre2\pcre2-10.00
+
+3. In a Windows command environment, chdir to the location of your bat and
+   exe programs.
+
+4. Run RunTest.bat. Test outputs will automatically be compared to expected
+   results, and discrepancies will be identified in the console output.
+
+To independently test the just-in-time compiler, run pcre2_jit_test.exe.
+
+
+BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
+
+z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
+The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
+applications can be supported through UNIX System Services, and in such an
+environment it should be possible to build PCRE2 in the same way as in other
+systems, with the EBCDIC related configuration settings, but it is not known if
+anybody has tried this.
+
+In native z/OS (without UNIX System Services) and in z/VM, special ports are
+required. For details, please see file 939 on this web site:
+
+  http://www.cbttape.org
+
+Everything in that location, source and executable, is in EBCDIC and native
+z/OS file formats. The port provides an API for LE languages such as COBOL and
+for the z/OS and z/VM versions of the Rexx languages.

+README file for PCRE2 (Perl-compatible regular expression library)
+------------------------------------------------------------------
+
+PCRE2 is a re-working of the original PCRE library to provide an entirely new
+API. The latest release of PCRE2 is always available in three alternative
+formats from:
+
+  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.gz
+  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.bz2
+  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.zip
+
+There is a mailing list for discussion about the development of PCRE (both the
+original and new APIs) at [email protected]. You can access the archives and
+subscribe or manage your subscription here:
+
+   https://lists.exim.org/mailman/listinfo/pcre-dev
+
+Please read the NEWS file if you are upgrading from a previous release. The
+contents of this README file are:

+  Retrieving configuration information
+  Shared libraries
+  Cross-compiling using autotools
+  Making new tarballs
+  Testing PCRE2
+  Character tables
+  File manifest
+
+
+The PCRE2 APIs
+--------------
+
+PCRE2 is written in C, and it has its own API. There are three sets of
+functions, one for the 8-bit library, which processes strings of bytes, one for
+the 16-bit library, which processes strings of 16-bit values, and one for the
+32-bit library, which processes strings of 32-bit values. There are no C++
+wrappers.
+
+The distribution does contain a set of C wrapper functions for the 8-bit
+library that are based on the POSIX regular expression API (see the pcre2posix
+man page). These can be found in a library called libpcre2-posix. Note that
+this just provides a POSIX calling interface to PCRE2; the regular expressions
+themselves still follow Perl syntax and semantics. The POSIX API is restricted,
+and does not give full access to all of PCRE2's facilities.
+
+The header file for the POSIX-style functions is called pcre2posix.h. The
+official POSIX name is regex.h, but I did not want to risk possible problems
+with existing files of that name by distributing it that way. To use PCRE2 with
+an existing program that uses the POSIX API, pcre2posix.h will have to be
+renamed or pointed at by a link.
+
+If you are using the POSIX interface to PCRE2 and there is already a POSIX
+regex library installed on your system, as well as worrying about the regex.h
+header file (as mentioned above), you must also take care when linking programs
+to ensure that they link with PCRE2's libpcre2-posix library. Otherwise they
+may pick up the POSIX functions of the same name from the other library.
+
+One way of avoiding this confusion is to compile PCRE2 with the addition of
+-Dregcomp=PCRE2regcomp (and similarly for the other POSIX functions) to the
+compiler flags (CFLAGS if you are using "configure" -- see below). This has the
+effect of renaming the functions so that the names no longer clash. Of course,
+you have to do the same thing for your applications, or write them using the
+new names.
+
+
+Documentation for PCRE2
+-----------------------
+
+If you install PCRE2 in the normal way on a Unix-like system, you will end up
+with a set of man pages whose names all start with "pcre2". The one that is
+just called "pcre2" lists all the others. In addition to these man pages, the
+PCRE2 documentation is supplied in two other forms:
+
+  1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
+     doc/pcre2test.txt in the source distribution. The first of these is a
+     concatenation of the text forms of all the section 3 man pages except the
+     listing of pcre2demo.c and those that summarize individual functions. The
+     other two are the text forms of the section 1 man pages for the pcre2grep
+     and pcre2test commands. These text forms are provided for ease of scanning
+     with text editors or similar tools. They are installed in
+     <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
+     (defaulting to /usr/local).
+
+  2. A set of files containing all the documentation in HTML form, hyperlinked
+     in various ways, and rooted in a file called index.html, is distributed in
+     doc/html and installed in <prefix>/share/doc/pcre2/html.
+
+
+Building PCRE2 on non-Unix-like systems
+---------------------------------------
+
+For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
+your system supports the use of "configure" and "make" you may be able to build
+PCRE2 using autotools in the same way as for many Unix-like systems.
+
+PCRE2 can also be configured using CMake, which can be run in various ways
+(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
+NON-AUTOTOOLS-BUILD has information about CMake.
+
+PCRE2 has been compiled on many different operating systems. It should be
+straightforward to build PCRE2 on any system that has a Standard C compiler and
+library, because it uses only Standard C functions.
+
+
+Building PCRE2 without using autotools
+--------------------------------------
+
+The use of autotools (in particular, libtool) is problematic in some
+environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
+file for ways of building PCRE2 without using autotools.
+
+
+Building PCRE2 using autotools
+------------------------------
+
+The following instructions assume the use of the widely used "configure; make;
+make install" (autotools) process.
+
+To build PCRE2 on system that supports autotools, first run the "configure"
+command from the PCRE2 distribution directory, with your current directory set
+to the directory where you want the files to be created. This command is a
+standard GNU "autoconf" configuration script, for which generic instructions
+are supplied in the file INSTALL.
+
+Most commonly, people build PCRE2 within its own distribution directory, and in
+this case, on many systems, just running "./configure" is sufficient. However,
+the usual methods of changing standard defaults are available. For example:
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+This command specifies that the C compiler should be run with the flags '-O2
+-Wall' instead of the default, and that "make install" should install PCRE2
+under /opt/local instead of the default /usr/local.
+
+If you want to build in a different directory, just run "configure" with that
+directory as current. For example, suppose you have unpacked the PCRE2 source
+into /source/pcre2/pcre2-xxx, but you want to build it in

+
+PCRE2 is written in C and is normally compiled as a C library. However, it is
+possible to build it as a C++ library, though the provided building apparatus
+does not have any features to support this.
+
+There are some optional features that can be included or omitted from the PCRE2
+library. They are also documented in the pcre2build man page.
+
+. By default, both shared and static libraries are built. You can change this
+  by adding one of these options to the "configure" command:
+
+  --disable-shared
+  --disable-static
+
+  (See also "Shared libraries on Unix-like systems" below.)
+
+. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
+  the "configure" command, the 16-bit library is also built. If you add
+  --enable-pcre2-32 to the "configure" command, the 32-bit library is also
+  built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
+  to disable building the 8-bit library.
+
+. If you want to include support for just-in-time (JIT) compiling, which can
+  give large performance improvements on certain platforms, add --enable-jit to
+  the "configure" command. This support is available only for certain hardware
+  architectures. If you try to enable it on an unsupported architecture, there
+  will be a compile time error. If you are running under SELinux you may also
+  want to add --enable-jit-sealloc, which enables the use of an execmem
+  allocator in JIT that is compatible with SELinux. This has no effect if JIT
+  is not enabled.
+
+. If you do not want to make use of the default support for UTF-8 Unicode
+  character strings in the 8-bit library, UTF-16 Unicode character strings in
+  the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
+  library, you can add --disable-unicode to the "configure" command. This
+  reduces the size of the libraries. It is not possible to configure one
+  library with Unicode support, and another without, in the same configuration.
+  It is also not possible to use --enable-ebcdic (see below) with Unicode
+  support, so if this option is set, you must also use --disable-unicode.
+
+  When Unicode support is available, the use of a UTF encoding still has to be
+  enabled by setting the PCRE2_UTF option at run time or starting a pattern
+  with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
+  either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
+
+  As well as supporting UTF strings, Unicode support includes support for the
+  \P, \p, and \X sequences that recognize Unicode character properties.
+  However, only the basic two-letter properties such as Lu are supported.
+  Escape sequences such as \d and \w in patterns do not by default make use of
+  Unicode properties, but can be made to do so by setting the PCRE2_UCP option
+  or starting a pattern with (*UCP).
+
+. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
+  of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
+  character as indicating the end of a line. Whatever you specify at build time
+  is the default; the caller of PCRE2 can change the selection at run time. The
+  default newline indicator is a single LF character (the Unix standard). You
+  can specify the default newline indicator by adding --enable-newline-is-cr,
+  --enable-newline-is-lf, --enable-newline-is-crlf,
+  --enable-newline-is-anycrlf, --enable-newline-is-any, or
+  --enable-newline-is-nul to the "configure" command, respectively.
+
+. By default, the sequence \R in a pattern matches any Unicode line ending
+  sequence. This is independent of the option specifying what PCRE2 considers
+  to be the end of a line (see above). However, the caller of PCRE2 can
+  restrict \R to match only CR, LF, or CRLF. You can make this the default by
+  adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
+
+. In a pattern, the escape sequence \C matches a single code unit, even in a
+  UTF mode. This can be dangerous because it breaks up multi-code-unit
+  characters. You can build PCRE2 with the use of \C permanently locked out by
+  adding --enable-never-backslash-C (note the upper case C) to the "configure"
+  command. When \C is allowed by the library, individual applications can lock
+  it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
+
+. PCRE2 has a counter that limits the depth of nesting of parentheses in a
+  pattern. This limits the amount of system stack that a pattern uses when it
+  is compiled. The default is 250, but you can change it by setting, for
+  example,
+
+  --with-parens-nest-limit=500
+
+. PCRE2 has a counter that can be set to limit the amount of computing resource
+  it uses when matching a pattern. If the limit is exceeded during a match, the
+  match fails. The default is ten million. You can change the default by
+  setting, for example,
+
+  --with-match-limit=500000
+
+  on the "configure" command. This is just the default; individual calls to
+  pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
+  discussion in the pcre2api man page (search for pcre2_set_match_limit).
+
+. There is a separate counter that limits the depth of nested backtracking
+  during a matching process, which indirectly limits the amount of heap memory
+  that is used. This also has a default of ten million, which is essentially
+  "unlimited". You can change the default by setting, for example,
+
+  --with-match-limit-depth=5000
+
+  There is more discussion in the pcre2api man page (search for
+  pcre2_set_depth_limit).
+
+. You can also set an explicit limit on the amount of heap memory used by
+  the pcre2_match() interpreter:
+
+  --with-heap-limit=500
+
+  The units are kilobytes. This limit does not apply when the JIT optimization
+  (which has its own memory control features) is used. There is more discussion
+  on the pcre2api man page (search for pcre2_set_heap_limit).
+
+. In the 8-bit library, the default maximum compiled pattern size is around
+  64K bytes. You can increase this by adding --with-link-size=3 to the
+  "configure" command. PCRE2 then uses three bytes instead of two for offsets
+  to different parts of the compiled pattern. In the 16-bit library,
+  --with-link-size=3 is the same as --with-link-size=4, which (in both
+  libraries) uses four-byte offsets. Increasing the internal link size reduces
+  performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
+  link size setting is ignored, as 4-byte offsets are always used.
+
+. For speed, PCRE2 uses four tables for manipulating and identifying characters
+  whose code point values are less than 256. By default, it uses a set of
+  tables for ASCII encoding that is part of the distribution. If you specify
+
+  --enable-rebuild-chartables
+
+  a program called dftables is compiled and run in the default C locale when
+  you obey "make". It builds a source file called pcre2_chartables.c. If you do
+  not specify this option, pcre2_chartables.c is created as a copy of
+  pcre2_chartables.c.dist. See "Character tables" below for further
+  information.
+
+. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
+  character code (as opposed to ASCII/Unicode) by specifying
+
+  --enable-ebcdic --disable-unicode
+
+  This automatically implies --enable-rebuild-chartables (see above). However,
+  when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
+  both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
+  which specifies that the code value for the EBCDIC NL character is 0x25
+  instead of the default 0x15.
+
+. If you specify --enable-debug, additional debugging code is included in the
+  build. This option is intended for use by the PCRE2 maintainers.
+
+. In environments where valgrind is installed, if you specify
+
+  --enable-valgrind
+
+  PCRE2 will use valgrind annotations to mark certain memory regions as
+  unaddressable. This allows it to detect invalid memory accesses, and is
+  mostly useful for debugging PCRE2 itself.
+
+. In environments where the gcc compiler is used and lcov version 1.6 or above
+  is installed, if you specify
+
+  --enable-coverage
+
+  the build process implements a code coverage report for the test suite. The
+  report is generated by running "make coverage". If ccache is installed on
+  your system, it must be disabled when building PCRE2 for coverage reporting.
+  You can do this by setting the environment variable CCACHE_DISABLE=1 before
+  running "make" to build PCRE2. There is more information about coverage
+  reporting in the "pcre2build" documentation.
+
+. When JIT support is enabled, pcre2grep automatically makes use of it, unless
+  you add --disable-pcre2grep-jit to the "configure" command.
+
+. On non-Windows sytems there is support for calling external scripts during
+  matching in the pcre2grep command via PCRE2's callout facility with string
+  arguments. This support can be disabled by adding --disable-pcre2grep-callout
+  to the "configure" command.
+
+. The pcre2grep program currently supports only 8-bit data files, and so
+  requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
+  libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
+  specifying one or both of
+
+  --enable-pcre2grep-libz
+  --enable-pcre2grep-libbz2
+
+  Of course, the relevant libraries must be installed on your system.
+
+. The default starting size (in bytes) of the internal buffer used by pcre2grep
+  can be set by, for example:
+
+  --with-pcre2grep-bufsize=51200
+
+  The value must be a plain integer. The default is 20480. The amount of memory
+  used by pcre2grep is actually three times this number, to allow for "before"
+  and "after" lines. If very long lines are encountered, the buffer is
+  automatically enlarged, up to a fixed maximum size.
+
+. The default maximum size of pcre2grep's internal buffer can be set by, for
+  example:
+
+  --with-pcre2grep-max-bufsize=2097152
+
+  The default is either 1048576 or the value of --with-pcre2grep-bufsize,
+  whichever is the larger.
+
+. It is possible to compile pcre2test so that it links with the libreadline
+  or libedit libraries, by specifying, respectively,
+
+  --enable-pcre2test-libreadline or --enable-pcre2test-libedit
+
+  If this is done, when pcre2test's input is from a terminal, it reads it using
+  the readline() function. This provides line-editing and history facilities.
+  Note that libreadline is GPL-licenced, so if you distribute a binary of
+  pcre2test linked in this way, there may be licensing issues. These can be
+  avoided by linking with libedit (which has a BSD licence) instead.
+
+  Enabling libreadline causes the -lreadline option to be added to the
+  pcre2test build. In many operating environments with a sytem-installed
+  readline library this is sufficient. However, in some environments (e.g. if
+  an unmodified distribution version of readline is in use), it may be
+  necessary to specify something like LIBS="-lncurses" as well. This is
+  because, to quote the readline INSTALL, "Readline uses the termcap functions,
+  but does not link with the termcap or curses library itself, allowing
+  applications which link with readline the to choose an appropriate library."
+  If you get error messages about missing functions tgetstr, tgetent, tputs,
+  tgetflag, or tgoto, this is the problem, and linking with the ncurses library
+  should fix it.
+
+. There is a special option called --enable-fuzz-support for use by people who
+  want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit
+  library. If set, it causes an extra library called libpcre2-fuzzsupport.a to
+  be built, but not installed. This contains a single function called
+  LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the
+  length of the string. When called, this function tries to compile the string
+  as a pattern, and if that succeeds, to match it. This is done both with no
+  options and with some random options bits that are generated from the string.
+  Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to
+  be created. This is normally run under valgrind or used when PCRE2 is
+  compiled with address sanitizing enabled. It calls the fuzzing function and
+  outputs information about it is doing. The input strings are specified by
+  arguments: if an argument starts with "=" the rest of it is a literal input
+  string. Otherwise, it is assumed to be a file name, and the contents of the
+  file are the test string.
+
+. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
+  which caused pcre2_match() to use individual blocks on the heap for
+  backtracking instead of recursive function calls (which use the stack). This
+  is now obsolete since pcre2_match() was refactored always to use the heap (in
+  a much more efficient way than before). This option is retained for backwards
+  compatibility, but has no effect other than to output a warning.
+
+The "configure" script builds the following files for the basic C library:
+
+. Makefile             the makefile that builds the library
+. src/config.h         build-time configuration options for the library
+. src/pcre2.h          the public PCRE2 header file
+. pcre2-config          script that shows the building settings such as CFLAGS
+                         that were set for "configure"
+. libpcre2-8.pc        )
+. libpcre2-16.pc       ) data for the pkg-config command
+. libpcre2-32.pc       )
+. libpcre2-posix.pc    )
+. libtool              script that builds shared and/or static libraries
+
+Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
+tarballs under the names config.h.generic and pcre2.h.generic. These are
+provided for those who have to build PCRE2 without using "configure" or CMake.
+If you use "configure" or CMake, the .generic versions are not used.
+
+The "configure" script also creates config.status, which is an executable
+script that can be run to recreate the configuration, and config.log, which
+contains compiler output from tests that "configure" runs.
+
+Once "configure" has run, you can run "make". This builds whichever of the
+libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
+program called pcre2test. If you enabled JIT support with --enable-jit, another
+test program called pcre2_jit_test is built as well. If the 8-bit library is
+built, libpcre2-posix and the pcre2grep command are also built. Running
+"make" with the -j option may speed up compilation on multiprocessor systems.
+
+The command "make check" runs all the appropriate tests. Details of the PCRE2
+tests are given below in a separate section of this document. The -j option of
+"make" can also be used when running the tests.
+
+You can use "make install" to install PCRE2 into live directories on your
+system. The following are installed (file names are all relative to the
+<prefix> that is set when "configure" is run):
+
+  Commands (bin):
+    pcre2test
+    pcre2grep (if 8-bit support is enabled)
+    pcre2-config
+
+  Libraries (lib):
+    libpcre2-8      (if 8-bit support is enabled)
+    libpcre2-16     (if 16-bit support is enabled)
+    libpcre2-32     (if 32-bit support is enabled)
+    libpcre2-posix  (if 8-bit support is enabled)
+
+  Configuration information (lib/pkgconfig):
+    libpcre2-8.pc
+    libpcre2-16.pc

+    pcre2grep.txt     the pcre2grep man page
+    pcre2-config.txt  the pcre2-config man page
+
+If you want to remove PCRE2 from your system, you can run "make uninstall".
+This removes all the files that "make install" installed. However, it does not
+remove any directories, because these are often shared with other programs.
+
+
+Retrieving configuration information
+------------------------------------
+
+Running "make install" installs the command pcre2-config, which can be used to
+recall information about the PCRE2 configuration and installation. For example:
+
+  pcre2-config --version
+
+prints the version number, and
+
+  pcre2-config --libs8
+
+outputs information about where the 8-bit library is installed. This command
+can be included in makefiles for programs that use PCRE2, saving the programmer
+from having to remember too many details. Run pcre2-config with no arguments to
+obtain a list of possible arguments.
+
+The pkg-config command is another system for saving and retrieving information
+about installed libraries. Instead of separate commands for each library, a
+single command is used. For example:
+
+  pkg-config --libs libpcre2-16
+
+The data is held in *.pc files that are installed in a directory called
+<prefix>/lib/pkgconfig.
+
+
+Shared libraries
+----------------
+
+The default distribution builds PCRE2 as shared libraries and static libraries,
+as long as the operating system supports shared libraries. Shared library
+support relies on the "libtool" script which is built as part of the
+"configure" process.
+
+The libtool script is used to compile and link both shared and static
+libraries. They are placed in a subdirectory called .libs when they are newly
+built. The programs pcre2test and pcre2grep are built to use these uninstalled
+libraries (by means of wrapper scripts in the case of shared libraries). When
+you use "make install" to install shared libraries, pcre2grep and pcre2test are
+automatically re-built to use the newly installed shared libraries before being
+installed themselves. However, the versions left in the build directory still
+use the uninstalled libraries.
+
+To build PCRE2 using static libraries only you must use --disable-shared when
+configuring it. For example:
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way. Similarly, you can use --disable-static to
+build only shared libraries.
+
+
+Cross-compiling using autotools
+-------------------------------
+
+You can specify CC and CFLAGS in the normal way to the "configure" command, in
+order to cross-compile PCRE2 for some other host. However, you should NOT
+specify --enable-rebuild-chartables, because if you do, the dftables.c source
+file is compiled and run on the local host, in order to generate the inbuilt
+character tables (the pcre2_chartables.c file). This will probably not work,
+because dftables.c needs to be compiled with the local compiler, not the cross
+compiler.
+
+When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
+created by making a copy of pcre2_chartables.c.dist, which is a default set of
+tables that assumes ASCII code. Cross-compiling with the default tables should
+not be a problem.
+
+If you need to modify the character tables when cross-compiling, you should
+move pcre2_chartables.c.dist out of the way, then compile dftables.c by hand
+and run it on the local host to make a new version of pcre2_chartables.c.dist.
+Then when you cross-compile PCRE2 this new version of the tables will be used.
+
+
+Making new tarballs
+-------------------
+
+The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
+zip formats. The command "make distcheck" does the same, but then does a trial
+build of the new distribution to ensure that it works.
+
+If you have modified any of the man page sources in the doc directory, you
+should first run the PrepareRelease script before making a distribution. This
+script creates the .txt and HTML forms of the documentation from the man pages.
+
+
+Testing PCRE2
+-------------
+
+To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
+There is another script called RunGrepTest that tests the pcre2grep command.
+When JIT support is enabled, a third test program called pcre2_jit_test is
+built. Both the scripts and all the program tests are run if you obey "make
+check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
+
+The RunTest script runs the pcre2test test program (which is documented in its
+own man page) on each of the relevant testinput files in the testdata
+directory, and compares the output with the contents of the corresponding
+testoutput files. RunTest uses a file called testtry to hold the main output
+from pcre2test. Other files whose names begin with "test" are used as working
+files in some tests.
+
+Some tests are relevant only when certain build-time options were selected. For
+example, the tests for UTF-8/16/32 features are run only when Unicode support
+is available. RunTest outputs a comment when it skips a test.
+
+Many (but not all) of the tests that are not skipped are run twice if JIT
+support is available. On the second run, JIT compilation is forced. This
+testing can be suppressed by putting "nojit" on the RunTest command line.
+
+The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
+libraries that are enabled. If you want to run just one set of tests, call
+RunTest with either the -8, -16 or -32 option.
+
+If valgrind is installed, you can run the tests under it by putting "valgrind"
+on the RunTest command line. To run pcre2test on just one or more specific test
+files, give their numbers as arguments to RunTest, for example:
+
+  RunTest 2 7 11
+
+You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
+end), or a number preceded by ~ to exclude a test. For example:
+
+  Runtest 3-15 ~10
+
+This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
+except test 13. Whatever order the arguments are in, the tests are always run
+in numerical order.
+
+You can also call RunTest with the single argument "list" to cause it to output
+a list of tests.
+
+The test sequence starts with "test 0", which is a special test that has no
+input file, and whose output is not checked. This is because it will be
+different on different hardware and with different configurations. The test
+exists in order to exercise some of pcre2test's code that would not otherwise
+be run.
+
+Tests 1 and 2 can always be run, as they expect only plain text strings (not
+UTF) and make no use of Unicode properties. The first test file can be fed
+directly into the perltest.sh script to check that Perl gives the same results.
+The only difference you should see is in the first few lines, where the Perl
+version is given instead of the PCRE2 version. The second set of tests check
+auxiliary functions, error detection, and run-time flags that are specific to
+PCRE2. It also uses the debugging flags to check some of the internals of
+pcre2_compile().
+
+If you build PCRE2 with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. For example, where the comparison test output contains
+[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
+cases. This is not a bug in PCRE2.
+
+Test 3 checks pcre2_maketables(), the facility for building a set of character
+tables for a specific locale and using them instead of the default tables. The
+script uses the "locale" command to check for the availability of the "fr_FR",
+"french", or "fr" locale, and uses the first one that it finds. If the "locale"
+command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
+the list of available locales, the third test cannot be run, and a comment is
+output to say why. If running this test produces an error like this:
+
+  ** Failed to set locale "fr_FR"
+
+it means that the given locale is not available on your system, despite being
+listed by "locale". This does not mean that PCRE2 is broken. There are three
+alternative output files for the third test, because three different versions
+of the French locale have been encountered. The test passes if its output
+matches any one of them.
+
+Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
+with the perltest.sh script, and test 5 checking PCRE2-specific things.
+
+Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
+non-UTF mode and UTF-mode with Unicode property support, respectively.
+
+Test 8 checks some internal offsets and code size features, but it is run only
+when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
+32-bit modes and for different link sizes, so there are different output files
+for each mode and link size.
+
+Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
+16-bit and 32-bit modes. These are tests that generate different output in
+8-bit mode. Each pair are for general cases and Unicode support, respectively.
+
+Test 13 checks the handling of non-UTF characters greater than 255 by
+pcre2_dfa_match() in 16-bit and 32-bit modes.
+
+Test 14 contains some special UTF and UCP tests that give different output for
+different code unit widths.
+
+Test 15 contains a number of tests that must not be run with JIT. They check,
+among other non-JIT things, the match-limiting features of the intepretive
+matcher.
+
+Test 16 is run only when JIT support is not available. It checks that an
+attempt to use JIT has the expected behaviour.
+
+Test 17 is run only when JIT support is available. It checks JIT complete and
+partial modes, match-limiting under JIT, and other JIT-specific features.
+
+Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
+the 8-bit library, without and with Unicode support, respectively.
+
+Test 20 checks the serialization functions by writing a set of compiled
+patterns to a file, and then reloading and checking them.
+
+Tests 21 and 22 test \C support when the use of \C is not locked out, without
+and with UTF support, respectively. Test 23 tests \C when it is locked out.
+
+Tests 24 and 25 test the experimental pattern conversion functions, without and
+with UTF support, respectively.
+
+
+Character tables
+----------------
+
+For speed, PCRE2 uses four tables for manipulating and identifying characters
+whose code point values are less than 256. By default, a set of tables that is
+built into the library is used. The pcre2_maketables() function can be called
+by an application to create a new set of tables in the current locale. This are
+passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
+compile context.
+
+The source file called pcre2_chartables.c contains the default set of tables.
+By default, this is created as a copy of pcre2_chartables.c.dist, which
+contains tables for ASCII coding. However, if --enable-rebuild-chartables is
+specified for ./configure, a different version of pcre2_chartables.c is built
+by the program dftables (compiled from dftables.c), which uses the ANSI C
+character handling functions such as isalnum(), isalpha(), isupper(),
+islower(), etc. to build the table sources. This means that the default C
+locale that is set for your system will control the contents of these default
+tables. You can change the default tables by editing pcre2_chartables.c and
+then re-building PCRE2. If you do this, you should take care to ensure that the
+file does not get automatically re-generated. The best way to do this is to
+move pcre2_chartables.c.dist out of the way and replace it with your customized
+tables.
+
+When the dftables program is run as a result of --enable-rebuild-chartables,
+it uses the default C locale that is set on your system. It does not pay
+attention to the LC_xxx environment variables. In other words, it uses the
+system's default locale rather than whatever the compiling user happens to have
+set. If you really do want to build a source set of character tables in a
+locale that is specified by the LC_xxx variables, you can run the dftables
+program by hand with the -L option. For example:
+
+  ./dftables -L pcre2_chartables.c.special
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes for code points less
+than 256. The final 256-byte table has bits indicating various character types,
+as follows:
+
+    1   white space character
+    2   letter
+    4   decimal digit
+    8   hexadecimal digit
+   16   alphanumeric or '_'
+  128   regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE2 to malfunction.

+###############################################################################
+# Run the PCRE2 tests using the pcre2test program. The appropriate tests are
+# selected, depending on which build-time options were used.
+#
+# When JIT support is available, all appropriate tests are run with and without
+# JIT, unless "-nojit" is given on the command line. There are also two tests
+# for JIT-specific features, one to be run when JIT support is available
+# (unless "-nojit" is specified), and one when it is not.
+#
+# Whichever of the 8-, 16- and 32-bit libraries exist are tested. It is also
+# possible to select which to test by giving "-8", "-16" or "-32" on the
+# command line.
+#
+# As well as "-nojit", "-8", "-16", and "-32", arguments for this script are
+# individual test numbers, ranges of tests such as 3-6 or 3- (meaning 3 to the
+# end), or a number preceded by ~ to exclude a test. For example, "3-15 ~10"
+# runs tests 3 to 15, excluding test 10, and just "~10" runs all the tests
+# except test 10. Whatever order the arguments are in, the tests are always run
+# in numerical order.
+#
+# Inappropriate tests are automatically skipped (with a comment to say so). For
+# example, if JIT support is not compiled, test 16 is skipped, whereas if JIT
+# support is compiled, test 15 is skipped.
+#
+# Other arguments can be one of the words "-valgrind", "-valgrind-log", or
+# "-sim" followed by an argument to run cross-compiled executables under a
+# simulator, for example:
+#
+# RunTest 3 -sim "qemu-arm -s 8388608"
+#
+# For backwards compatibility, -nojit, -valgrind, -valgrind-log, and -sim may
+# be given without the leading "-" character.
+#
+# When PCRE2 is compiled by clang with -fsanitize arguments, some tests need
+# very much more stack than normal. In environments where the stack can be
+# set at runtime, -bigstack sets a gigantic stack.
+#
+# There are two special cases where only one argument is allowed:
+#
+# If the first and only argument is "ebcdic", the script runs the special
+# EBCDIC test that can be useful for checking certain EBCDIC features, even
+# when run in an ASCII environment. PCRE2 must be built with EBCDIC support for
+# this test to be run.
+#
+# If the script is obeyed as "RunTest list", a list of available tests is
+# output, but none of them are run.

+@rem MS Windows batch file to run pcre2test on testfiles with the correct
+@rem options. This file must use CRLF linebreaks to function properly,
+@rem and requires both pcre2test and pcre2grep.
+@rem
+@rem ------------------------ HISTORY ----------------------------------
+@rem This file was originally contributed to PCRE1 by Ralf Junker, and touched
+@rem up by Daniel Richard G. Tests 10-12 added by Philip H.
+@rem Philip H also changed test 3 to use "wintest" files.
+@rem
+@rem Updated by Tom Fortmann to support explicit test numbers on the command
+@rem line. Added argument validation and added error reporting.
+@rem
+@rem Sheri Pierce added logic to skip feature dependent tests
+@rem tests 4 5 7 10 12 14 19 and 22 require Unicode support
+@rem 8 requires Unicode and link size 2
+@rem 16 requires absence of jit support
+@rem 17 requires presence of jit support
+@rem Sheri P also added override tests for study and jit testing
+@rem Zoltan Herczeg added libpcre16 support
+@rem Zoltan Herczeg added libpcre32 support
+@rem -------------------------------------------------------------------
+@rem
+@rem The file was converted for PCRE2 by PH, February 2015.
+@rem Updated for new test 14 (moving others up a number), August 2015.
+@rem Tidied and updated for new tests 21, 22, 23 by PH, October 2015.
+@rem PH added missing "set type" for test 22, April 2016.

+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+#    It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
+#    it also sets the <UPPERCASED_NAME>_FOUND variable.
+#    The package is found if all variables listed are TRUE.
+#    Example:
+#
+#    FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
+#
+#    LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and 
+#    LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
+#    If it is not found and REQUIRED was used, it fails with FATAL_ERROR, 
+#    independent whether QUIET was used or not.
+#    If it is found, the location is reported using the VAR1 argument, so 
+#    here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
+#    If the second argument is DEFAULT_MSG, the message in the failure case will 
+#    be "Could NOT find LibXml2", if you don't like this message you can specify
+#    your own custom failure message there.

+\`configure' configures PCRE2 10.31 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:

+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+/* PCRE2 is written in Standard C, but there are a few non-standard things it
+can cope with, allowing it to run on SunOS4 and other "close to standard"
+systems.
+
+In environments that support the GNU autotools, config.h.in is converted into
+config.h by the "configure" script. In environments that use CMake,
+config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
+hand" without using "configure" or CMake, you should copy the distributed
+config.h.generic to config.h, and edit the macro definitions to be the way you
+need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
+so that config.h is included at the start of every source.
+
+Alternatively, you can avoid editing by using -D on the compiler command line
+to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
+but if you do, default values will be taken from config.h for non-boolean
+macros that are not defined on the command line.
+
+Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be defined
+(conventionally to 1) for TRUE, and not defined at all for FALSE. All such
+macros are listed as a commented #undef in config.h.generic. Macros such as
+MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
+surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
+
+PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
+HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
+sure both macros are undefined; an emulation function will then be used. */])

+## why we pick this rather obscure method:
+## - Don't want to use -MD because we'd like the dependencies to end
+##   up in a subdir.  Having to rename by hand is ugly.
+##   (We might end up doing this anyway to support other compilers.)
+## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse
+##   than renaming).

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.

+
+
+GENERAL
+
+The basic PCRE2 library consists entirely of code written in Standard C, and so
+should compile successfully on any system that has a Standard C compiler and
+library.
+
+The PCRE2 distribution includes a "configure" file for use by the
+configure/make (autotools) build system, as found in many Unix-like
+environments. The README file contains information about the options for
+"configure".
+
+There is also support for CMake, which some users prefer, especially in Windows
+environments, though it can also be run in Unix-like environments. See the
+section entitled "Building PCRE2 on Windows with CMake" below.
+
+Versions of src/config.h and src/pcre2.h are distributed in the PCRE2 tarballs
+under the names src/config.h.generic and src/pcre2.h.generic. These are
+provided for those who build PCRE2 without using "configure" or CMake. If you
+use "configure" or CMake, the .generic versions are not used.
+
+
+GENERIC INSTRUCTIONS FOR THE PCRE2 C LIBRARY
+
+The following are generic instructions for building the PCRE2 C library "by
+hand". If you are going to use CMake, this section does not apply to you; you
+can skip ahead to the CMake section.
+
+ (1) Copy or rename the file src/config.h.generic as src/config.h, and edit the
+     macro settings that it contains to whatever is appropriate for your
+     environment. In particular, you can alter the definition of the NEWLINE
+     macro to specify what character(s) you want to be interpreted as line
+     terminators by default.
+
+     When you compile any of the PCRE2 modules, you must specify
+     -DHAVE_CONFIG_H to your compiler so that src/config.h is included in the
+     sources.
+
+     An alternative approach is not to edit src/config.h, but to use -D on the
+     compiler command line to make any changes that you need to the
+     configuration options. In this case -DHAVE_CONFIG_H must not be set.
+
+     NOTE: There have been occasions when the way in which certain parameters
+     in src/config.h are used has changed between releases. (In the
+     configure/make world, this is handled automatically.) When upgrading to a
+     new release, you are strongly advised to review src/config.h.generic
+     before re-using what you had previously.
+
+ (2) Copy or rename the file src/pcre2.h.generic as src/pcre2.h.
+
+ (3) EITHER:
+       Copy or rename file src/pcre2_chartables.c.dist as
+       src/pcre2_chartables.c.
+
+     OR:
+       Compile src/dftables.c as a stand-alone program (using -DHAVE_CONFIG_H
+       if you have set up src/config.h), and then run it with the single
+       argument "src/pcre2_chartables.c". This generates a set of standard
+       character tables and writes them to that file. The tables are generated
+       using the default C locale for your system. If you want to use a locale
+       that is specified by LC_xxx environment variables, add the -L option to
+       the dftables command. You must use this method if you are building on a
+       system that uses EBCDIC code.
+
+     The tables in src/pcre2_chartables.c are defaults. The caller of PCRE2 can
+     specify alternative tables at run time.
+
+ (4) For an 8-bit library, compile the following source files from the src
+     directory, setting -DPCRE2_CODE_UNIT_WIDTH=8 as a compiler option. Also
+     set -DHAVE_CONFIG_H if you have set up src/config.h with your
+     configuration, or else use other -D settings to change the configuration
+     as required.

+       pcre2_chartables.c
+       pcre2_compile.c
+       pcre2_config.c
+       pcre2_context.c
+       pcre2_convert.c
+       pcre2_dfa_match.c
+       pcre2_error.c
+       pcre2_extuni.c
+       pcre2_find_bracket.c
+       pcre2_jit_compile.c
+       pcre2_maketables.c
+       pcre2_match.c
+       pcre2_match_data.c
+       pcre2_newline.c
+       pcre2_ord2utf.c
+       pcre2_pattern_info.c
+       pcre2_serialize.c
+       pcre2_string_utils.c
+       pcre2_study.c
+       pcre2_substitute.c
+       pcre2_substring.c
+       pcre2_tables.c
+       pcre2_ucd.c
+       pcre2_valid_utf.c
+       pcre2_xclass.c
+
+     Make sure that you include -I. in the compiler command (or equivalent for
+     an unusual compiler) so that all included PCRE2 header files are first
+     sought in the src directory under the current directory. Otherwise you run
+     the risk of picking up a previously-installed file from somewhere else.
+
+     Note that you must compile pcre2_jit_compile.c, even if you have not
+     defined SUPPORT_JIT in src/config.h, because when JIT support is not
+     configured, dummy functions are compiled. When JIT support IS configured,
+     pcre2_jit_compile.c #includes other files from the sljit subdirectory,
+     all of whose names begin with "sljit". It also #includes
+     src/pcre2_jit_match.c and src/pcre2_jit_misc.c, so you should not compile
+     these yourself.
+
+     Not also that the pcre2_fuzzsupport.c file contains special code that is
+     useful to those who want to run fuzzing tests on the PCRE2 library. Unless
+     you are doing that, you can ignore it.
+
+ (5) Now link all the compiled code into an object library in whichever form
+     your system keeps such libraries. This is the basic PCRE2 C 8-bit library.
+     If your system has static and shared libraries, you may have to do this
+     once for each type.
+
+ (6) If you want to build a 16-bit library or 32-bit library (as well as, or
+     instead of the 8-bit library) just supply 16 or 32 as the value of
+     -DPCRE2_CODE_UNIT_WIDTH when you are compiling.
+
+ (7) If you want to build the POSIX wrapper functions (which apply only to the
+     8-bit library), ensure that you have the src/pcre2posix.h file and then
+     compile src/pcre2posix.c. Link the result (on its own) as the pcre2posix
+     library.
+
+ (8) The pcre2test program can be linked with any combination of the 8-bit,
+     16-bit and 32-bit libraries (depending on what you selected in
+     src/config.h). Compile src/pcre2test.c; don't forget -DHAVE_CONFIG_H if
+     necessary, but do NOT define PCRE2_CODE_UNIT_WIDTH. Then link with the
+     appropriate library/ies. If you compiled an 8-bit library, pcre2test also
+     needs the pcre2posix wrapper library.
+
+ (9) Run pcre2test on the testinput files in the testdata directory, and check
+     that the output matches the corresponding testoutput files. There are
+     comments about what each test does in the section entitled "Testing PCRE2"
+     in the README file. If you compiled more than one of the 8-bit, 16-bit and
+     32-bit libraries, you need to run pcre2test with the -16 option to do
+     16-bit tests and with the -32 option to do 32-bit tests.
+
+     Some tests are relevant only when certain build-time options are selected.
+     For example, test 4 is for Unicode support, and will not run if you have
+     built PCRE2 without it. See the comments at the start of each testinput
+     file. If you have a suitable Unix-like shell, the RunTest script will run
+     the appropriate tests for you. The command "RunTest list" will output a
+     list of all the tests.
+
+     Note that the supplied files are in Unix format, with just LF characters
+     as line terminators. You may need to edit them to change this if your
+     system uses a different convention.
+
+(10) If you have built PCRE2 with SUPPORT_JIT, the JIT features can be tested
+     by running pcre2test with the -jit option. This is done automatically by
+     the RunTest script. You might also like to build and run the freestanding
+     JIT test program, src/pcre2_jit_test.c.
+
+(11) If you want to use the pcre2grep command, compile and link
+     src/pcre2grep.c; it uses only the basic 8-bit PCRE2 library (it does not
+     need the pcre2posix library). If you have built the PCRE2 library with JIT
+     support by defining SUPPORT_JIT in src/config.h, you can also define
+     SUPPORT_PCRE2GREP_JIT, which causes pcre2grep to make use of JIT (unless
+     it is run with --no-jit). If you define SUPPORT_PCRE2GREP_JIT without
+     defining SUPPORT_JIT, pcre2grep does not try to make use of JIT.
+
+
+STACK SIZE IN WINDOWS ENVIRONMENTS
+
+Prior to release 10.30 the default system stack size of 1Mb in some Windows
+environments caused issues with some tests. This should no longer be the case
+for 10.30 and later releases.
+
+
+LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
+
+If you want to statically link a program against a PCRE2 library in the form of
+a non-dll .a file, you must define PCRE2_STATIC before including src/pcre2.h.
+
+
+CALLING CONVENTIONS IN WINDOWS ENVIRONMENTS
+
+It is possible to compile programs to use different calling conventions using
+MSVC. Search the web for "calling conventions" for more information. To make it
+easier to change the calling convention for the exported functions in the
+PCRE2 library, the macro PCRE2_CALL_CONVENTION is present in all the external
+definitions. It can be set externally when compiling (e.g. in CFLAGS). If it is
+not set, it defaults to empty; the default calling convention is then used
+(which is what is wanted most of the time).
+
+
+COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE2 ON WINDOWS WITH CMAKE")
+
+There are two ways of building PCRE2 using the "configure, make, make install"
+paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
+the same thing; they are completely different from each other. There is also
+support for building using CMake, which some users find a more straightforward
+way of building PCRE2 under Windows.
+
+The MinGW home page (http://www.mingw.org/) says this:
+
+  MinGW: A collection of freely available and freely distributable Windows
+  specific header files and import libraries combined with GNU toolsets that
+  allow one to produce native Windows programs that do not rely on any
+  3rd-party C runtime DLLs.
+
+The Cygwin home page (http://www.cygwin.com/) says this:
+
+  Cygwin is a Linux-like environment for Windows. It consists of two parts:
+
+  . A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
+    substantial Linux API functionality
+
+  . A collection of tools which provide Linux look and feel.
+
+On both MinGW and Cygwin, PCRE2 should build correctly using:
+
+  ./configure && make && make install
+
+This should create two libraries called libpcre2-8 and libpcre2-posix. These
+are independent libraries: when you link with libpcre2-posix you must also link
+with libpcre2-8, which contains the basic functions.
+
+Using Cygwin's compiler generates libraries and executables that depend on
+cygwin1.dll. If a library that is generated this way is distributed,
+cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
+licence, this forces not only PCRE2 to be under the GPL, but also the entire
+application. A distributor who wants to keep their own code proprietary must
+purchase an appropriate Cygwin licence.
+
+MinGW has no such restrictions. The MinGW compiler generates a library or
+executable that can run standalone on Windows without any third party dll or
+licensing issues.
+
+But there is more complication:
+
+If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
+to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
+front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
+gcc and MinGW's gcc). So, a user can:
+
+. Build native binaries by using MinGW or by getting Cygwin and using
+  -mno-cygwin.
+
+. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
+  compiler flags.
+
+The test files that are supplied with PCRE2 are in UNIX format, with LF
+characters as line terminators. Unless your PCRE2 library uses a default
+newline option that includes LF as a valid newline, it may be necessary to
+change the line terminators in the test files to get some of the tests to work.
+
+
+BUILDING PCRE2 ON WINDOWS WITH CMAKE
+
+CMake is an alternative configuration facility that can be used instead of
+"configure". CMake creates project files (make files, solution files, etc.)
+tailored to numerous development environments, including Visual Studio,
+Borland, Msys, MinGW, NMake, and Unix. If possible, use short paths with no
+spaces in the names for your CMake installation and your PCRE2 source and build
+directories.
+
+The following instructions were contributed by a PCRE1 user, but they should
+also work for PCRE2. If they are not followed exactly, errors may occur. In the
+event that errors do occur, it is recommended that you delete the CMake cache
+before attempting to repeat the CMake build process. In the CMake GUI, the
+cache can be deleted by selecting "File > Delete Cache".
+
+1.  Install the latest CMake version available from http://www.cmake.org/, and
+    ensure that cmake\bin is on your path.
+
+2.  Unzip (retaining folder structure) the PCRE2 source tree into a source
+    directory such as C:\pcre2. You should ensure your local date and time
+    is not earlier than the file dates in your source dir if the release is
+    very new.
+
+3.  Create a new, empty build directory, preferably a subdirectory of the
+    source dir. For example, C:\pcre2\pcre2-xx\build.
+
+4.  Run cmake-gui from the Shell envirornment of your build tool, for example,
+    Msys for Msys/MinGW or Visual Studio Command Prompt for VC/VC++. Do not try
+    to start Cmake from the Windows Start menu, as this can lead to errors.
+
+5.  Enter C:\pcre2\pcre2-xx and C:\pcre2\pcre2-xx\build for the source and
+    build directories, respectively.
+
+6.  Hit the "Configure" button.
+
+7.  Select the particular IDE / build tool that you are using (Visual
+    Studio, MSYS makefiles, MinGW makefiles, etc.)
+
+8.  The GUI will then list several configuration options. This is where
+    you can disable Unicode support or select other PCRE2 optional features.
+
+9.  Hit "Configure" again. The adjacent "Generate" button should now be
+    active.
+
+10. Hit "Generate".
+
+11. The build directory should now contain a usable build system, be it a
+    solution file for Visual Studio, makefiles for MinGW, etc. Exit from
+    cmake-gui and use the generated build system with your compiler or IDE.
+    E.g., for MinGW you can run "make", or for Visual Studio, open the PCRE2
+    solution, select the desired configuration (Debug, or Release, etc.) and
+    build the ALL_BUILD project.
+
+12. If during configuration with cmake-gui you've elected to build the test
+    programs, you can execute them by building the test project. E.g., for
+    MinGW: "make test"; for Visual Studio build the RUN_TESTS project. The
+    most recent build configuration is targeted by the tests. A summary of
+    test results is presented. Complete test output is subsequently
+    available for review in Testing\Temporary under your build dir.
+
+
+TESTING WITH RUNTEST.BAT
+
+If configured with CMake, building the test project ("make test" or building
+ALL_TESTS in Visual Studio) creates (and runs) pcre2_test.bat (and depending
+on your configuration options, possibly other test programs) in the build
+directory. The pcre2_test.bat script runs RunTest.bat with correct source and
+exe paths.
+
+For manual testing with RunTest.bat, provided the build dir is a subdirectory
+of the source directory: Open command shell window. Chdir to the location
+of your pcre2test.exe and pcre2grep.exe programs. Call RunTest.bat with
+"..\RunTest.Bat" or "..\..\RunTest.bat" as appropriate.
+
+To run only a particular test with RunTest.Bat provide a test number argument.
+
+Otherwise:
+
+1. Copy RunTest.bat into the directory where pcre2test.exe and pcre2grep.exe
+   have been created.
+
+2. Edit RunTest.bat to indentify the full or relative location of
+   the pcre2 source (wherein which the testdata folder resides), e.g.:
+
+   set srcdir=C:\pcre2\pcre2-10.00
+
+3. In a Windows command environment, chdir to the location of your bat and
+   exe programs.
+
+4. Run RunTest.bat. Test outputs will automatically be compared to expected
+   results, and discrepancies will be identified in the console output.
+
+To independently test the just-in-time compiler, run pcre2_jit_test.exe.
+
+
+BUILDING PCRE2 ON NATIVE Z/OS AND Z/VM
+
+z/OS and z/VM are operating systems for mainframe computers, produced by IBM.
+The character code used is EBCDIC, not ASCII or Unicode. In z/OS, UNIX APIs and
+applications can be supported through UNIX System Services, and in such an
+environment it should be possible to build PCRE2 in the same way as in other
+systems, with the EBCDIC related configuration settings, but it is not known if
+anybody has tried this.
+
+In native z/OS (without UNIX System Services) and in z/VM, special ports are
+required. For details, please see file 939 on this web site:
+
+  http://www.cbttape.org
+
+Everything in that location, source and executable, is in EBCDIC and native
+z/OS file formats. The port provides an API for LE languages such as COBOL and
+for the z/OS and z/VM versions of the Rexx languages.

+
+PCRE2 is a re-working of the original PCRE library to provide an entirely new

+formats from:
+
+  ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-xxx.tar.gz

+
+
+The PCRE2 APIs
+--------------
+
+PCRE2 is written in C, and it has its own API. There are three sets of
+functions, one for the 8-bit library, which processes strings of bytes, one for
+the 16-bit library, which processes strings of 16-bit values, and one for the
+32-bit library, which processes strings of 32-bit values. There are no C++
+wrappers.
+
+The distribution does contain a set of C wrapper functions for the 8-bit
+library that are based on the POSIX regular expression API (see the pcre2posix
+man page). These can be found in a library called libpcre2-posix. Note that
+this just provides a POSIX calling interface to PCRE2; the regular expressions
+themselves still follow Perl syntax and semantics. The POSIX API is restricted,
+and does not give full access to all of PCRE2's facilities.
+
+The header file for the POSIX-style functions is called pcre2posix.h. The
+official POSIX name is regex.h, but I did not want to risk possible problems
+with existing files of that name by distributing it that way. To use PCRE2 with
+an existing program that uses the POSIX API, pcre2posix.h will have to be
+renamed or pointed at by a link.
+
+If you are using the POSIX interface to PCRE2 and there is already a POSIX
+regex library installed on your system, as well as worrying about the regex.h
+header file (as mentioned above), you must also take care when linking programs
+to ensure that they link with PCRE2's libpcre2-posix library. Otherwise they
+may pick up the POSIX functions of the same name from the other library.
+
+One way of avoiding this confusion is to compile PCRE2 with the addition of
+-Dregcomp=PCRE2regcomp (and similarly for the other POSIX functions) to the
+compiler flags (CFLAGS if you are using "configure" -- see below). This has the
+effect of renaming the functions so that the names no longer clash. Of course,
+you have to do the same thing for your applications, or write them using the
+new names.
+
+
+Documentation for PCRE2
+-----------------------
+
+If you install PCRE2 in the normal way on a Unix-like system, you will end up
+with a set of man pages whose names all start with "pcre2". The one that is
+just called "pcre2" lists all the others. In addition to these man pages, the
+PCRE2 documentation is supplied in two other forms:
+
+  1. There are files called doc/pcre2.txt, doc/pcre2grep.txt, and
+     doc/pcre2test.txt in the source distribution. The first of these is a
+     concatenation of the text forms of all the section 3 man pages except the
+     listing of pcre2demo.c and those that summarize individual functions. The
+     other two are the text forms of the section 1 man pages for the pcre2grep
+     and pcre2test commands. These text forms are provided for ease of scanning
+     with text editors or similar tools. They are installed in
+     <prefix>/share/doc/pcre2, where <prefix> is the installation prefix
+     (defaulting to /usr/local).
+
+  2. A set of files containing all the documentation in HTML form, hyperlinked
+     in various ways, and rooted in a file called index.html, is distributed in
+     doc/html and installed in <prefix>/share/doc/pcre2/html.
+
+
+Building PCRE2 on non-Unix-like systems
+---------------------------------------
+
+For a non-Unix-like system, please read the file NON-AUTOTOOLS-BUILD, though if
+your system supports the use of "configure" and "make" you may be able to build
+PCRE2 using autotools in the same way as for many Unix-like systems.
+
+PCRE2 can also be configured using CMake, which can be run in various ways
+(command line, GUI, etc). This creates Makefiles, solution files, etc. The file
+NON-AUTOTOOLS-BUILD has information about CMake.
+
+PCRE2 has been compiled on many different operating systems. It should be
+straightforward to build PCRE2 on any system that has a Standard C compiler and
+library, because it uses only Standard C functions.
+
+
+Building PCRE2 without using autotools
+--------------------------------------
+
+The use of autotools (in particular, libtool) is problematic in some
+environments, even some that are Unix or Unix-like. See the NON-AUTOTOOLS-BUILD
+file for ways of building PCRE2 without using autotools.
+
+
+Building PCRE2 using autotools
+------------------------------
+
+The following instructions assume the use of the widely used "configure; make;
+make install" (autotools) process.
+
+To build PCRE2 on system that supports autotools, first run the "configure"
+command from the PCRE2 distribution directory, with your current directory set
+to the directory where you want the files to be created. This command is a
+standard GNU "autoconf" configuration script, for which generic instructions
+are supplied in the file INSTALL.
+
+Most commonly, people build PCRE2 within its own distribution directory, and in
+this case, on many systems, just running "./configure" is sufficient. However,
+the usual methods of changing standard defaults are available. For example:
+
+CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
+
+This command specifies that the C compiler should be run with the flags '-O2
+-Wall' instead of the default, and that "make install" should install PCRE2
+under /opt/local instead of the default /usr/local.
+
+If you want to build in a different directory, just run "configure" with that
+directory as current. For example, suppose you have unpacked the PCRE2 source
+into /source/pcre2/pcre2-xxx, but you want to build it in
+/build/pcre2/pcre2-xxx:
+
+cd /build/pcre2/pcre2-xxx
+/source/pcre2/pcre2-xxx/configure
+
+PCRE2 is written in C and is normally compiled as a C library. However, it is
+possible to build it as a C++ library, though the provided building apparatus
+does not have any features to support this.
+
+There are some optional features that can be included or omitted from the PCRE2
+library. They are also documented in the pcre2build man page.
+
+. By default, both shared and static libraries are built. You can change this
+  by adding one of these options to the "configure" command:
+
+  --disable-shared
+  --disable-static
+
+  (See also "Shared libraries on Unix-like systems" below.)
+
+. By default, only the 8-bit library is built. If you add --enable-pcre2-16 to
+  the "configure" command, the 16-bit library is also built. If you add
+  --enable-pcre2-32 to the "configure" command, the 32-bit library is also
+  built. If you want only the 16-bit or 32-bit library, use --disable-pcre2-8
+  to disable building the 8-bit library.
+
+. If you want to include support for just-in-time (JIT) compiling, which can
+  give large performance improvements on certain platforms, add --enable-jit to
+  the "configure" command. This support is available only for certain hardware
+  architectures. If you try to enable it on an unsupported architecture, there
+  will be a compile time error. If you are running under SELinux you may also
+  want to add --enable-jit-sealloc, which enables the use of an execmem
+  allocator in JIT that is compatible with SELinux. This has no effect if JIT
+  is not enabled.
+
+. If you do not want to make use of the default support for UTF-8 Unicode
+  character strings in the 8-bit library, UTF-16 Unicode character strings in
+  the 16-bit library, or UTF-32 Unicode character strings in the 32-bit
+  library, you can add --disable-unicode to the "configure" command. This
+  reduces the size of the libraries. It is not possible to configure one
+  library with Unicode support, and another without, in the same configuration.
+  It is also not possible to use --enable-ebcdic (see below) with Unicode
+  support, so if this option is set, you must also use --disable-unicode.
+
+  When Unicode support is available, the use of a UTF encoding still has to be
+  enabled by setting the PCRE2_UTF option at run time or starting a pattern
+  with (*UTF). When PCRE2 is compiled with Unicode support, its input can only
+  either be ASCII or UTF-8/16/32, even when running on EBCDIC platforms.
+
+  As well as supporting UTF strings, Unicode support includes support for the
+  \P, \p, and \X sequences that recognize Unicode character properties.
+  However, only the basic two-letter properties such as Lu are supported.
+  Escape sequences such as \d and \w in patterns do not by default make use of
+  Unicode properties, but can be made to do so by setting the PCRE2_UCP option
+  or starting a pattern with (*UCP).
+
+. You can build PCRE2 to recognize either CR or LF or the sequence CRLF, or any
+  of the preceding, or any of the Unicode newline sequences, or the NUL (zero)
+  character as indicating the end of a line. Whatever you specify at build time
+  is the default; the caller of PCRE2 can change the selection at run time. The
+  default newline indicator is a single LF character (the Unix standard). You
+  can specify the default newline indicator by adding --enable-newline-is-cr,
+  --enable-newline-is-lf, --enable-newline-is-crlf,
+  --enable-newline-is-anycrlf, --enable-newline-is-any, or
+  --enable-newline-is-nul to the "configure" command, respectively.
+
+. By default, the sequence \R in a pattern matches any Unicode line ending
+  sequence. This is independent of the option specifying what PCRE2 considers
+  to be the end of a line (see above). However, the caller of PCRE2 can
+  restrict \R to match only CR, LF, or CRLF. You can make this the default by
+  adding --enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
+
+. In a pattern, the escape sequence \C matches a single code unit, even in a
+  UTF mode. This can be dangerous because it breaks up multi-code-unit
+  characters. You can build PCRE2 with the use of \C permanently locked out by
+  adding --enable-never-backslash-C (note the upper case C) to the "configure"
+  command. When \C is allowed by the library, individual applications can lock
+  it out by calling pcre2_compile() with the PCRE2_NEVER_BACKSLASH_C option.
+
+. PCRE2 has a counter that limits the depth of nesting of parentheses in a
+  pattern. This limits the amount of system stack that a pattern uses when it
+  is compiled. The default is 250, but you can change it by setting, for
+  example,
+
+  --with-parens-nest-limit=500
+
+. PCRE2 has a counter that can be set to limit the amount of computing resource
+  it uses when matching a pattern. If the limit is exceeded during a match, the
+  match fails. The default is ten million. You can change the default by
+  setting, for example,
+
+  --with-match-limit=500000
+
+  on the "configure" command. This is just the default; individual calls to
+  pcre2_match() or pcre2_dfa_match() can supply their own value. There is more
+  discussion in the pcre2api man page (search for pcre2_set_match_limit).
+
+. There is a separate counter that limits the depth of nested backtracking
+  during a matching process, which indirectly limits the amount of heap memory
+  that is used. This also has a default of ten million, which is essentially
+  "unlimited". You can change the default by setting, for example,
+
+  --with-match-limit-depth=5000
+
+  There is more discussion in the pcre2api man page (search for
+  pcre2_set_depth_limit).
+
+. You can also set an explicit limit on the amount of heap memory used by
+  the pcre2_match() interpreter:
+
+  --with-heap-limit=500
+
+  The units are kilobytes. This limit does not apply when the JIT optimization
+  (which has its own memory control features) is used. There is more discussion
+  on the pcre2api man page (search for pcre2_set_heap_limit).
+
+. In the 8-bit library, the default maximum compiled pattern size is around
+  64K bytes. You can increase this by adding --with-link-size=3 to the
+  "configure" command. PCRE2 then uses three bytes instead of two for offsets
+  to different parts of the compiled pattern. In the 16-bit library,
+  --with-link-size=3 is the same as --with-link-size=4, which (in both
+  libraries) uses four-byte offsets. Increasing the internal link size reduces
+  performance in the 8-bit and 16-bit libraries. In the 32-bit library, the
+  link size setting is ignored, as 4-byte offsets are always used.
+
+. For speed, PCRE2 uses four tables for manipulating and identifying characters
+  whose code point values are less than 256. By default, it uses a set of
+  tables for ASCII encoding that is part of the distribution. If you specify
+
+  --enable-rebuild-chartables
+
+  a program called dftables is compiled and run in the default C locale when
+  you obey "make". It builds a source file called pcre2_chartables.c. If you do
+  not specify this option, pcre2_chartables.c is created as a copy of
+  pcre2_chartables.c.dist. See "Character tables" below for further
+  information.
+
+. It is possible to compile PCRE2 for use on systems that use EBCDIC as their
+  character code (as opposed to ASCII/Unicode) by specifying
+
+  --enable-ebcdic --disable-unicode
+
+  This automatically implies --enable-rebuild-chartables (see above). However,
+  when PCRE2 is built this way, it always operates in EBCDIC. It cannot support
+  both EBCDIC and UTF-8/16/32. There is a second option, --enable-ebcdic-nl25,
+  which specifies that the code value for the EBCDIC NL character is 0x25
+  instead of the default 0x15.
+
+. If you specify --enable-debug, additional debugging code is included in the
+  build. This option is intended for use by the PCRE2 maintainers.
+
+. In environments where valgrind is installed, if you specify
+
+  --enable-valgrind
+
+  PCRE2 will use valgrind annotations to mark certain memory regions as
+  unaddressable. This allows it to detect invalid memory accesses, and is
+  mostly useful for debugging PCRE2 itself.
+
+. In environments where the gcc compiler is used and lcov version 1.6 or above
+  is installed, if you specify
+
+  --enable-coverage
+
+  the build process implements a code coverage report for the test suite. The
+  report is generated by running "make coverage". If ccache is installed on
+  your system, it must be disabled when building PCRE2 for coverage reporting.
+  You can do this by setting the environment variable CCACHE_DISABLE=1 before
+  running "make" to build PCRE2. There is more information about coverage
+  reporting in the "pcre2build" documentation.
+
+. When JIT support is enabled, pcre2grep automatically makes use of it, unless
+  you add --disable-pcre2grep-jit to the "configure" command.
+
+. On non-Windows sytems there is support for calling external scripts during
+  matching in the pcre2grep command via PCRE2's callout facility with string
+  arguments. This support can be disabled by adding --disable-pcre2grep-callout
+  to the "configure" command.
+
+. The pcre2grep program currently supports only 8-bit data files, and so
+  requires the 8-bit PCRE2 library. It is possible to compile pcre2grep to use
+  libz and/or libbz2, in order to read .gz and .bz2 files (respectively), by
+  specifying one or both of
+
+  --enable-pcre2grep-libz
+  --enable-pcre2grep-libbz2
+
+  Of course, the relevant libraries must be installed on your system.
+
+. The default starting size (in bytes) of the internal buffer used by pcre2grep
+  can be set by, for example:
+
+  --with-pcre2grep-bufsize=51200
+
+  The value must be a plain integer. The default is 20480. The amount of memory
+  used by pcre2grep is actually three times this number, to allow for "before"
+  and "after" lines. If very long lines are encountered, the buffer is
+  automatically enlarged, up to a fixed maximum size.
+
+. The default maximum size of pcre2grep's internal buffer can be set by, for
+  example:
+
+  --with-pcre2grep-max-bufsize=2097152
+
+  The default is either 1048576 or the value of --with-pcre2grep-bufsize,
+  whichever is the larger.
+
+. It is possible to compile pcre2test so that it links with the libreadline
+  or libedit libraries, by specifying, respectively,
+
+  --enable-pcre2test-libreadline or --enable-pcre2test-libedit
+
+  If this is done, when pcre2test's input is from a terminal, it reads it using
+  the readline() function. This provides line-editing and history facilities.
+  Note that libreadline is GPL-licenced, so if you distribute a binary of
+  pcre2test linked in this way, there may be licensing issues. These can be
+  avoided by linking with libedit (which has a BSD licence) instead.
+
+  Enabling libreadline causes the -lreadline option to be added to the
+  pcre2test build. In many operating environments with a sytem-installed
+  readline library this is sufficient. However, in some environments (e.g. if
+  an unmodified distribution version of readline is in use), it may be
+  necessary to specify something like LIBS="-lncurses" as well. This is
+  because, to quote the readline INSTALL, "Readline uses the termcap functions,
+  but does not link with the termcap or curses library itself, allowing
+  applications which link with readline the to choose an appropriate library."
+  If you get error messages about missing functions tgetstr, tgetent, tputs,
+  tgetflag, or tgoto, this is the problem, and linking with the ncurses library
+  should fix it.
+
+. There is a special option called --enable-fuzz-support for use by people who
+  want to run fuzzing tests on PCRE2. At present this applies only to the 8-bit
+  library. If set, it causes an extra library called libpcre2-fuzzsupport.a to
+  be built, but not installed. This contains a single function called
+  LLVMFuzzerTestOneInput() whose arguments are a pointer to a string and the
+  length of the string. When called, this function tries to compile the string
+  as a pattern, and if that succeeds, to match it. This is done both with no
+  options and with some random options bits that are generated from the string.
+  Setting --enable-fuzz-support also causes a binary called pcre2fuzzcheck to
+  be created. This is normally run under valgrind or used when PCRE2 is
+  compiled with address sanitizing enabled. It calls the fuzzing function and
+  outputs information about it is doing. The input strings are specified by
+  arguments: if an argument starts with "=" the rest of it is a literal input
+  string. Otherwise, it is assumed to be a file name, and the contents of the
+  file are the test string.
+
+. Releases before 10.30 could be compiled with --disable-stack-for-recursion,
+  which caused pcre2_match() to use individual blocks on the heap for
+  backtracking instead of recursive function calls (which use the stack). This
+  is now obsolete since pcre2_match() was refactored always to use the heap (in
+  a much more efficient way than before). This option is retained for backwards
+  compatibility, but has no effect other than to output a warning.
+
+The "configure" script builds the following files for the basic C library:
+
+. Makefile             the makefile that builds the library
+. src/config.h         build-time configuration options for the library
+. src/pcre2.h          the public PCRE2 header file
+. pcre2-config          script that shows the building settings such as CFLAGS
+                         that were set for "configure"
+. libpcre2-8.pc        )
+. libpcre2-16.pc       ) data for the pkg-config command
+. libpcre2-32.pc       )
+. libpcre2-posix.pc    )
+. libtool              script that builds shared and/or static libraries
+
+Versions of config.h and pcre2.h are distributed in the src directory of PCRE2
+tarballs under the names config.h.generic and pcre2.h.generic. These are
+provided for those who have to build PCRE2 without using "configure" or CMake.
+If you use "configure" or CMake, the .generic versions are not used.
+
+The "configure" script also creates config.status, which is an executable
+script that can be run to recreate the configuration, and config.log, which
+contains compiler output from tests that "configure" runs.
+
+Once "configure" has run, you can run "make". This builds whichever of the
+libraries libpcre2-8, libpcre2-16 and libpcre2-32 are configured, and a test
+program called pcre2test. If you enabled JIT support with --enable-jit, another
+test program called pcre2_jit_test is built as well. If the 8-bit library is
+built, libpcre2-posix and the pcre2grep command are also built. Running
+"make" with the -j option may speed up compilation on multiprocessor systems.
+
+The command "make check" runs all the appropriate tests. Details of the PCRE2
+tests are given below in a separate section of this document. The -j option of
+"make" can also be used when running the tests.
+
+You can use "make install" to install PCRE2 into live directories on your
+system. The following are installed (file names are all relative to the
+<prefix> that is set when "configure" is run):
+
+  Commands (bin):
+    pcre2test
+    pcre2grep (if 8-bit support is enabled)
+    pcre2-config
+
+  Libraries (lib):
+    libpcre2-8      (if 8-bit support is enabled)
+    libpcre2-16     (if 16-bit support is enabled)

+    libpcre2-posix  (if 8-bit support is enabled)
+
+  Configuration information (lib/pkgconfig):

+
+If you want to remove PCRE2 from your system, you can run "make uninstall".
+This removes all the files that "make install" installed. However, it does not
+remove any directories, because these are often shared with other programs.
+
+
+Retrieving configuration information
+------------------------------------
+
+Running "make install" installs the command pcre2-config, which can be used to
+recall information about the PCRE2 configuration and installation. For example:
+
+  pcre2-config --version
+
+prints the version number, and
+
+  pcre2-config --libs8
+
+outputs information about where the 8-bit library is installed. This command
+can be included in makefiles for programs that use PCRE2, saving the programmer
+from having to remember too many details. Run pcre2-config with no arguments to
+obtain a list of possible arguments.
+
+The pkg-config command is another system for saving and retrieving information
+about installed libraries. Instead of separate commands for each library, a
+single command is used. For example:
+
+  pkg-config --libs libpcre2-16
+
+The data is held in *.pc files that are installed in a directory called
+<prefix>/lib/pkgconfig.
+
+
+Shared libraries
+----------------
+
+The default distribution builds PCRE2 as shared libraries and static libraries,
+as long as the operating system supports shared libraries. Shared library
+support relies on the "libtool" script which is built as part of the
+"configure" process.
+
+The libtool script is used to compile and link both shared and static
+libraries. They are placed in a subdirectory called .libs when they are newly
+built. The programs pcre2test and pcre2grep are built to use these uninstalled
+libraries (by means of wrapper scripts in the case of shared libraries). When
+you use "make install" to install shared libraries, pcre2grep and pcre2test are
+automatically re-built to use the newly installed shared libraries before being
+installed themselves. However, the versions left in the build directory still
+use the uninstalled libraries.
+
+To build PCRE2 using static libraries only you must use --disable-shared when
+configuring it. For example:
+
+./configure --prefix=/usr/gnu --disable-shared
+
+Then run "make" in the usual way. Similarly, you can use --disable-static to
+build only shared libraries.
+
+
+Cross-compiling using autotools
+-------------------------------
+
+You can specify CC and CFLAGS in the normal way to the "configure" command, in
+order to cross-compile PCRE2 for some other host. However, you should NOT
+specify --enable-rebuild-chartables, because if you do, the dftables.c source
+file is compiled and run on the local host, in order to generate the inbuilt
+character tables (the pcre2_chartables.c file). This will probably not work,
+because dftables.c needs to be compiled with the local compiler, not the cross
+compiler.
+
+When --enable-rebuild-chartables is not specified, pcre2_chartables.c is
+created by making a copy of pcre2_chartables.c.dist, which is a default set of
+tables that assumes ASCII code. Cross-compiling with the default tables should
+not be a problem.
+
+If you need to modify the character tables when cross-compiling, you should
+move pcre2_chartables.c.dist out of the way, then compile dftables.c by hand
+and run it on the local host to make a new version of pcre2_chartables.c.dist.
+Then when you cross-compile PCRE2 this new version of the tables will be used.
+
+
+Making new tarballs
+-------------------
+
+The command "make dist" creates three PCRE2 tarballs, in tar.gz, tar.bz2, and
+zip formats. The command "make distcheck" does the same, but then does a trial
+build of the new distribution to ensure that it works.
+
+If you have modified any of the man page sources in the doc directory, you
+should first run the PrepareRelease script before making a distribution. This
+script creates the .txt and HTML forms of the documentation from the man pages.
+
+
+Testing PCRE2
+-------------
+
+To test the basic PCRE2 library on a Unix-like system, run the RunTest script.
+There is another script called RunGrepTest that tests the pcre2grep command.
+When JIT support is enabled, a third test program called pcre2_jit_test is
+built. Both the scripts and all the program tests are run if you obey "make
+check". For other environments, see the instructions in NON-AUTOTOOLS-BUILD.
+
+The RunTest script runs the pcre2test test program (which is documented in its
+own man page) on each of the relevant testinput files in the testdata
+directory, and compares the output with the contents of the corresponding
+testoutput files. RunTest uses a file called testtry to hold the main output
+from pcre2test. Other files whose names begin with "test" are used as working
+files in some tests.
+
+Some tests are relevant only when certain build-time options were selected. For
+example, the tests for UTF-8/16/32 features are run only when Unicode support
+is available. RunTest outputs a comment when it skips a test.
+
+Many (but not all) of the tests that are not skipped are run twice if JIT
+support is available. On the second run, JIT compilation is forced. This
+testing can be suppressed by putting "nojit" on the RunTest command line.
+
+The entire set of tests is run once for each of the 8-bit, 16-bit and 32-bit
+libraries that are enabled. If you want to run just one set of tests, call
+RunTest with either the -8, -16 or -32 option.
+
+If valgrind is installed, you can run the tests under it by putting "valgrind"
+on the RunTest command line. To run pcre2test on just one or more specific test
+files, give their numbers as arguments to RunTest, for example:
+
+  RunTest 2 7 11
+
+You can also specify ranges of tests such as 3-6 or 3- (meaning 3 to the
+end), or a number preceded by ~ to exclude a test. For example:
+
+  Runtest 3-15 ~10
+
+This runs tests 3 to 15, excluding test 10, and just ~13 runs all the tests
+except test 13. Whatever order the arguments are in, the tests are always run
+in numerical order.
+
+You can also call RunTest with the single argument "list" to cause it to output
+a list of tests.
+
+The test sequence starts with "test 0", which is a special test that has no
+input file, and whose output is not checked. This is because it will be
+different on different hardware and with different configurations. The test
+exists in order to exercise some of pcre2test's code that would not otherwise
+be run.
+
+Tests 1 and 2 can always be run, as they expect only plain text strings (not
+UTF) and make no use of Unicode properties. The first test file can be fed
+directly into the perltest.sh script to check that Perl gives the same results.
+The only difference you should see is in the first few lines, where the Perl
+version is given instead of the PCRE2 version. The second set of tests check
+auxiliary functions, error detection, and run-time flags that are specific to
+PCRE2. It also uses the debugging flags to check some of the internals of
+pcre2_compile().
+
+If you build PCRE2 with a locale setting that is not the standard C locale, the
+character tables may be different (see next paragraph). In some cases, this may
+cause failures in the second set of tests. For example, in a locale where the
+isprint() function yields TRUE for characters in the range 128-255, the use of
+[:isascii:] inside a character class defines a different set of characters, and
+this shows up in this test as a difference in the compiled code, which is being
+listed for checking. For example, where the comparison test output contains
+[\x00-\x7f] the test might contain [\x00-\xff], and similarly in some other
+cases. This is not a bug in PCRE2.
+
+Test 3 checks pcre2_maketables(), the facility for building a set of character
+tables for a specific locale and using them instead of the default tables. The
+script uses the "locale" command to check for the availability of the "fr_FR",
+"french", or "fr" locale, and uses the first one that it finds. If the "locale"
+command fails, or if its output doesn't include "fr_FR", "french", or "fr" in
+the list of available locales, the third test cannot be run, and a comment is
+output to say why. If running this test produces an error like this:
+
+  ** Failed to set locale "fr_FR"
+
+it means that the given locale is not available on your system, despite being
+listed by "locale". This does not mean that PCRE2 is broken. There are three
+alternative output files for the third test, because three different versions
+of the French locale have been encountered. The test passes if its output
+matches any one of them.
+
+Tests 4 and 5 check UTF and Unicode property support, test 4 being compatible
+with the perltest.sh script, and test 5 checking PCRE2-specific things.
+
+Tests 6 and 7 check the pcre2_dfa_match() alternative matching function, in
+non-UTF mode and UTF-mode with Unicode property support, respectively.
+
+Test 8 checks some internal offsets and code size features, but it is run only
+when Unicode support is enabled. The output is different in 8-bit, 16-bit, and
+32-bit modes and for different link sizes, so there are different output files
+for each mode and link size.
+
+Tests 9 and 10 are run only in 8-bit mode, and tests 11 and 12 are run only in
+16-bit and 32-bit modes. These are tests that generate different output in
+8-bit mode. Each pair are for general cases and Unicode support, respectively.
+
+Test 13 checks the handling of non-UTF characters greater than 255 by
+pcre2_dfa_match() in 16-bit and 32-bit modes.
+
+Test 14 contains some special UTF and UCP tests that give different output for
+different code unit widths.
+
+Test 15 contains a number of tests that must not be run with JIT. They check,
+among other non-JIT things, the match-limiting features of the intepretive
+matcher.
+
+Test 16 is run only when JIT support is not available. It checks that an
+attempt to use JIT has the expected behaviour.
+
+Test 17 is run only when JIT support is available. It checks JIT complete and
+partial modes, match-limiting under JIT, and other JIT-specific features.
+
+Tests 18 and 19 are run only in 8-bit mode. They check the POSIX interface to
+the 8-bit library, without and with Unicode support, respectively.
+
+Test 20 checks the serialization functions by writing a set of compiled
+patterns to a file, and then reloading and checking them.
+
+Tests 21 and 22 test \C support when the use of \C is not locked out, without
+and with UTF support, respectively. Test 23 tests \C when it is locked out.
+
+Tests 24 and 25 test the experimental pattern conversion functions, without and
+with UTF support, respectively.
+
+
+Character tables
+----------------
+
+For speed, PCRE2 uses four tables for manipulating and identifying characters
+whose code point values are less than 256. By default, a set of tables that is
+built into the library is used. The pcre2_maketables() function can be called
+by an application to create a new set of tables in the current locale. This are
+passed to PCRE2 by calling pcre2_set_character_tables() to put a pointer into a
+compile context.
+
+The source file called pcre2_chartables.c contains the default set of tables.
+By default, this is created as a copy of pcre2_chartables.c.dist, which
+contains tables for ASCII coding. However, if --enable-rebuild-chartables is
+specified for ./configure, a different version of pcre2_chartables.c is built
+by the program dftables (compiled from dftables.c), which uses the ANSI C
+character handling functions such as isalnum(), isalpha(), isupper(),
+islower(), etc. to build the table sources. This means that the default C
+locale that is set for your system will control the contents of these default
+tables. You can change the default tables by editing pcre2_chartables.c and
+then re-building PCRE2. If you do this, you should take care to ensure that the
+file does not get automatically re-generated. The best way to do this is to
+move pcre2_chartables.c.dist out of the way and replace it with your customized
+tables.
+
+When the dftables program is run as a result of --enable-rebuild-chartables,
+it uses the default C locale that is set on your system. It does not pay
+attention to the LC_xxx environment variables. In other words, it uses the
+system's default locale rather than whatever the compiling user happens to have
+set. If you really do want to build a source set of character tables in a
+locale that is specified by the LC_xxx variables, you can run the dftables
+program by hand with the -L option. For example:
+
+  ./dftables -L pcre2_chartables.c.special
+
+The first two 256-byte tables provide lower casing and case flipping functions,
+respectively. The next table consists of three 32-byte bit maps which identify
+digits, "word" characters, and white space, respectively. These are used when
+building 32-byte bit maps that represent character classes for code points less
+than 256. The final 256-byte table has bits indicating various character types,
+as follows:
+
+    1   white space character
+    2   letter
+    4   decimal digit
+    8   hexadecimal digit
+   16   alphanumeric or '_'
+  128   regular expression metacharacter or binary zero
+
+You should not alter the set of characters that contain the 128 bit, as that
+will cause PCRE2 to malfunction.

+<P>
+PCRE2 is the name used for a revised API for the PCRE library, which is a set
+of functions, written in C, that implement regular expression pattern matching
+using the same syntax and semantics as Perl, with just a few differences. Some
+features that appeared in Python and the original PCRE before they appeared in
+Perl are also available using the Python syntax. There is also some support for
+one or two .NET and Oniguruma syntax items, and there are options for
+requesting some minor changes that give better ECMAScript (aka JavaScript)
+compatibility.
+</P>
+<P>
+The source code for PCRE2 can be compiled to support 8-bit, 16-bit, or 32-bit
+code units, which means that up to three separate libraries may be installed.
+The original work to extend PCRE to 16-bit and 32-bit code units was done by
+Zoltan Herczeg and Christian Persch, respectively. In all three cases, strings
+can be interpreted either as one character per code unit, or as UTF-encoded
+Unicode, with support for Unicode general category properties. Unicode support
+is optional at build time (but is the default). However, processing strings as
+UTF code units must be enabled explicitly at run time. The version of Unicode
+in use can be discovered by running
+<pre>
+  pcre2test -C
+</PRE>
+</P>
+<P>
+The three libraries contain identical sets of functions, with names ending in
+_8, _16, or _32, respectively (for example, <b>pcre2_compile_8()</b>). However,
+by defining PCRE2_CODE_UNIT_WIDTH to be 8, 16, or 32, a program that uses just
+one code unit width can be written using generic names such as
+<b>pcre2_compile()</b>, and the documentation is written assuming that this is
+the case.
+</P>
+<P>
+In addition to the Perl-compatible matching function, PCRE2 contains an
+alternative function that matches the same compiled patterns in a different
+way. In certain circumstances, the alternative function has some advantages.
+For a discussion of the two matching algorithms, see the
+<a href="pcre2matching.html"><b>pcre2matching</b></a>
+page.
+</P>
+<P>
+Details of exactly which Perl regular expression features are and are not
+supported by PCRE2 are given in separate documents. See the
+<a href="pcre2pattern.html"><b>pcre2pattern</b></a>
+and
+<a href="pcre2compat.html"><b>pcre2compat</b></a>
+pages. There is a syntax summary in the
+<a href="pcre2syntax.html"><b>pcre2syntax</b></a>
+page.
+</P>
+<P>
+Some features of PCRE2 can be included, excluded, or changed when the library
+is built. The
+<a href="pcre2_config.html"><b>pcre2_config()</b></a>
+function makes it possible for a client to discover which features are
+available. The features themselves are described in the
+<a href="pcre2build.html"><b>pcre2build</b></a>
+page. Documentation about building PCRE2 for various operating systems can be
+found in the
+<a href="README.txt"><b>README</b></a>
+and
+<a href="NON-AUTOTOOLS-BUILD.txt"><b>NON-AUTOTOOLS_BUILD</b></a>
+files in the source distribution.
+</P>
+<P>
+The libraries contains a number of undocumented internal functions and data
+tables that are used by more than one of the exported external functions, but
+which are not intended for use by external callers. Their names all begin with
+"_pcre2", which hopefully will not provoke any name clashes. In some
+environments, it is possible to control which external symbols are exported
+when a shared library is built, and in these cases the undocumented symbols are
+not exported.
+</P>
+<br><a name="SEC2" href="#TOC1">SECURITY CONSIDERATIONS</a><br>
+<P>
+If you are using PCRE2 in a non-UTF application that permits users to supply
+arbitrary patterns for compilation, you should be aware of a feature that
+allows users to turn on UTF support from within a pattern. For example, an
+8-bit pattern that begins with "(*UTF)" turns on UTF-8 mode, which interprets
+patterns and subjects as strings of UTF-8 code units instead of individual
+8-bit characters. This causes both the pattern and any data against which it is
+matched to be checked for UTF-8 validity. If the data string is very long, such
+a check might use sufficiently many resources as to cause your application to
+lose performance.
+</P>
+<P>
+One way of guarding against this possibility is to use the
+<b>pcre2_pattern_info()</b> function to check the compiled pattern's options for
+PCRE2_UTF. Alternatively, you can set the PCRE2_NEVER_UTF option when calling
+<b>pcre2_compile()</b>. This causes a compile time error if the pattern contains
+a UTF-setting sequence.
+</P>
+<P>
+The use of Unicode properties for character types such as \d can also be
+enabled from within the pattern, by specifying "(*UCP)". This feature can be
+disallowed by setting the PCRE2_NEVER_UCP option.
+</P>
+<P>
+If your application is one that supports UTF, be aware that validity checking
+can take time. If the same data string is to be matched many times, you can use
+the PCRE2_NO_UTF_CHECK option for the second and subsequent matches to avoid
+running redundant checks.
+</P>
+<P>
+The use of the \C escape sequence in a UTF-8 or UTF-16 pattern can lead to
+problems, because it may leave the current matching point in the middle of a
+multi-code-unit character. The PCRE2_NEVER_BACKSLASH_C option can be used by an
+application to lock out the use of \C, causing a compile-time error if it is
+encountered. It is also possible to build PCRE2 with the use of \C permanently
+disabled.
+</P>
+<P>
+Another way that performance can be hit is by running a pattern that has a very
+large search tree against a string that will never match. Nested unlimited
+repeats in a pattern are a common example. PCRE2 provides some protection
+against this: see the <b>pcre2_set_match_limit()</b> function in the
+<a href="pcre2api.html"><b>pcre2api</b></a>
+page. There is a similar function called <b>pcre2_set_depth_limit()</b> that can
+be used to restrict the amount of memory that is used.
+</P>
+<br><a name="SEC3" href="#TOC1">USER DOCUMENTATION</a><br>
+<P>
+The user documentation for PCRE2 comprises a number of different sections. In
+the "man" format, each of these is a separate "man page". In the HTML format,
+each is a separate page, linked from the index page. In the plain text format,
+the descriptions of the <b>pcre2grep</b> and <b>pcre2test</b> programs are in
+files called <b>pcre2grep.txt</b> and <b>pcre2test.txt</b>, respectively. The
+remaining sections, except for the <b>pcre2demo</b> section (which is a program
+listing), and the short pages for individual functions, are concatenated in
+<b>pcre2.txt</b>, for ease of searching. The sections are as follows:

+This function scans a compiled regular expression and calls the <i>callback()</i>
+function for each callout within the pattern. The yield of the function is zero
+for success and non-zero otherwise. The arguments are:
+<pre>
+  <i>code</i>           Points to the compiled pattern
+  <i>callback</i>       The callback function
+  <i>callout_data</i>   User data that is passed to the callback
+</pre>
+The <i>callback()</i> function is passed a pointer to a data block containing
+the following fields (not necessarily in this order):
+<pre>
+  uint32_t   <i>version</i>                Block version number

+  PCRE2_SIZE <i>callout_string_length</i>  Length of callout string
+  PCRE2_SPTR <i>callout_string</i>         Points to callout string or is NULL
+</pre>
+The second argument passed to the <b>callback()</b> function is the callout data
+that was passed to <b>pcre2_callout_enumerate()</b>. The <b>callback()</b>
+function must return zero for success. Any other value causes the pattern scan

+DESCRIPTION
+</b><br>
+<P>
+This function compiles a regular expression pattern into an internal form. Its
+arguments are:
+<pre>
+  <i>pattern</i>       A string containing expression to be compiled
+  <i>length</i>        The length of the string or PCRE2_ZERO_TERMINATED
+  <i>options</i>       Option bits
+  <i>errorcode</i>     Where to put an error code
+  <i>erroffset</i>     Where to put an error offset
+  <i>ccontext</i>      Pointer to a compile context or NULL
+</pre>
+The length of the pattern and any error offset that is returned are in code
+units, not characters. A compile context is needed only if you want to provide
+custom memory allocation functions, or to provide an external function for
+system stack size checking, or to change one or more of these parameters:
+<pre>
+  What \R matches (Unicode newlines, or CR, LF, CRLF only);
+  PCRE2's character tables;
+  The newline character sequence;
+  The compile time nested parentheses limit;
+  The maximum pattern length (in code units) that is allowed.
+  The additional options bits (see pcre2_set_compile_extra_options())
+</pre>
+The option bits are:
+<pre>
+  PCRE2_ANCHORED           Force pattern anchoring
+  PCRE2_ALLOW_EMPTY_CLASS  Allow empty classes
+  PCRE2_ALT_BSUX           Alternative handling of \u, \U, and \x
+  PCRE2_ALT_CIRCUMFLEX     Alternative handling of ^ in multiline mode
+  PCRE2_ALT_VERBNAMES      Process backslashes in verb names
+  PCRE2_AUTO_CALLOUT       Compile automatic callouts
+  PCRE2_CASELESS           Do caseless matching
+  PCRE2_DOLLAR_ENDONLY     $ not to match newline at end
+  PCRE2_DOTALL             . matches anything including NL
+  PCRE2_DUPNAMES           Allow duplicate names for subpatterns
+  PCRE2_ENDANCHORED        Pattern can match only at end of subject
+  PCRE2_EXTENDED           Ignore white space and # comments
+  PCRE2_FIRSTLINE          Force matching to be before newline
+  PCRE2_LITERAL            Pattern characters are all literal
+  PCRE2_MATCH_UNSET_BACKREF  Match unset back references
+  PCRE2_MULTILINE          ^ and $ match newlines within data
+  PCRE2_NEVER_BACKSLASH_C  Lock out the use of \C in patterns
+  PCRE2_NEVER_UCP          Lock out PCRE2_UCP, e.g. via (*UCP)
+  PCRE2_NEVER_UTF          Lock out PCRE2_UTF, e.g. via (*UTF)
+  PCRE2_NO_AUTO_CAPTURE    Disable numbered capturing paren-
+                            theses (named ones available)
+  PCRE2_NO_AUTO_POSSESS    Disable auto-possessification
+  PCRE2_NO_DOTSTAR_ANCHOR  Disable automatic anchoring for .*
+  PCRE2_NO_START_OPTIMIZE  Disable match-time start optimizations
+  PCRE2_NO_UTF_CHECK       Do not check the pattern for UTF validity
+                             (only relevant if PCRE2_UTF is set)
+  PCRE2_UCP                Use Unicode properties for \d, \w, etc.
+  PCRE2_UNGREEDY           Invert greediness of quantifiers
+  PCRE2_USE_OFFSET_LIMIT   Enable offset limit for unanchored matching
+  PCRE2_UTF                Treat pattern and subjects as UTF strings
+</pre>
+PCRE2 must be built with Unicode support (the default) in order to use
+PCRE2_UTF, PCRE2_UCP and related options.

+The yield of the function is a pointer to a private data structure that
+contains the compiled pattern, or NULL if an error was detected.

+  <i>what</i>     A code specifying what information is required
+  <i>where</i>    Points to where to put the information
+</pre>
+If <i>where</i> is NULL, the function returns the amount of memory needed for

+  PCRE2_CONFIG_BSR             Indicates what \R matches by default:
+                                 PCRE2_BSR_UNICODE

+  PCRE2_CONFIG_COMPILED_WIDTHS Which of 8/16/32 support was compiled
+  PCRE2_CONFIG_DEPTHLIMIT      Default backtracking depth limit
+  PCRE2_CONFIG_HEAPLIMIT       Default heap memory limit
+  PCRE2_CONFIG_JIT             Availability of just-in-time compiler support (1=yes 0=no)
+  PCRE2_CONFIG_JITTARGET       Information (a string) about the target architecture for the JIT compiler
+  PCRE2_CONFIG_LINKSIZE        Configured internal link size (2, 3, 4)
+  PCRE2_CONFIG_MATCHLIMIT      Default internal resource limit
+  PCRE2_CONFIG_NEVER_BACKSLASH_C  Whether or not \C is disabled
+  PCRE2_CONFIG_NEWLINE         Code for the default newline sequence:
+                                 PCRE2_NEWLINE_CR
+                                 PCRE2_NEWLINE_LF

+  PCRE2_CONFIG_UNICODE         Availability of Unicode support (1=yes 0=no)
+  PCRE2_CONFIG_UNICODE_VERSION The Unicode version (a string)
+  PCRE2_CONFIG_VERSION         The PCRE2 version (a string)
+</pre>
+The function yields a non-negative value on success or the negative value
+PCRE2_ERROR_BADOPTION otherwise. This is also the result for the
+PCRE2_CONFIG_JITTARGET code if JIT support is not available. When a string is
+requested, the function returns the number of code units used, including the
+terminating zero.

+<P>
+This function matches a compiled regular expression against a given subject
+string, using an alternative matching algorithm that scans the subject string
+just once (except when processing lookaround assertions). This function is
+<i>not</i> Perl-compatible (the Perl-compatible matching function is
+<b>pcre2_match()</b>). The arguments for this function are:
+<pre>
+  <i>code</i>         Points to the compiled pattern
+  <i>subject</i>      Points to the subject string
+  <i>length</i>       Length of the subject string
+  <i>startoffset</i>  Offset in the subject at which to start matching
+  <i>options</i>      Option bits
+  <i>match_data</i>   Points to a match data block, for results
+  <i>mcontext</i>     Points to a match context, or is NULL
+  <i>workspace</i>    Points to a vector of ints used as working space
+  <i>wscount</i>      Number of elements in the vector
+</pre>
+For <b>pcre2_dfa_match()</b>, a match context is needed only if you want to set
+up a callout function or specify the match and/or the recursion depth limits.
+The <i>length</i> and <i>startoffset</i> values are code units, not characters.
+The options are:
+<pre>
+  PCRE2_ANCHORED          Match only at the first position
+  PCRE2_ENDANCHORED       Pattern can match only at end of subject
+  PCRE2_NOTBOL            Subject is not the beginning of a line
+  PCRE2_NOTEOL            Subject is not the end of a line
+  PCRE2_NOTEMPTY          An empty string is not a valid match
+  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
+  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
+                           was set at compile time)
+  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match

+DESCRIPTION

+<P>
+This function provides control over the memory used by JIT as a run-time stack
+when <b>pcre2_match()</b> or <b>pcre2_jit_match()</b> is called with a pattern
+that has been successfully processed by the JIT compiler. The information that
+determines which stack is used is put into a match context that is subsequently
+passed to a matching function. The arguments of this function are:
+<pre>
+  mcontext       a pointer to a match context
+  callback       a callback function
+  callback_data  a JIT stack or a value to be passed to the callback
+</PRE>
+</P>
+<P>
+If <i>callback</i> is NULL and <i>callback_data</i> is NULL, an internal 32K
+block on the machine stack is used.
+</P>
+<P>
+If <i>callback</i> is NULL and <i>callback_data</i> is not NULL,
+<i>callback_data</i> must be a valid JIT stack, the result of calling
+<b>pcre2_jit_stack_create()</b>.
+</P>
+<P>
+If <i>callback</i> not NULL, it is called with <i>callback_data</i> as an
+argument at the start of matching, in order to set up a JIT stack. If the
+result is NULL, the internal 32K stack is used; otherwise the return value must
+be a valid JIT stack, the result of calling <b>pcre2_jit_stack_create()</b>.
+</P>
+<P>
+You may safely use the same JIT stack for multiple patterns, as long as they
+are all matched in the same thread. In a multithread application, each thread
+must use its own JIT stack. For more details, see the

+DESCRIPTION

+<P>
+This function is used to create a stack for use by the code compiled by the JIT
+compiler. The first two arguments are a starting size for the stack, and a
+maximum size to which it is allowed to grow. The final argument is a general
+context, for memory allocation functions, or NULL for standard memory
+allocation. The result can be passed to the JIT run-time code by calling
+<b>pcre2_jit_stack_assign()</b> to associate the stack with a compiled pattern,
+which can then be processed by <b>pcre2_match()</b> or <b>pcre2_jit_match()</b>.
+A maximum stack size of 512K to 1M should be more than enough for any pattern.

+<br><b>
+DESCRIPTION
+</b><br>
+<P>
+This function matches a compiled regular expression against a given subject
+string, using a matching algorithm that is similar to Perl's. It returns
+offsets to what it has matched and to captured substrings via the
+<b>match_data</b> block, which can be processed by functions with names that
+start with <b>pcre2_get_ovector_...()</b> or <b>pcre2_substring_...()</b>. The
+return from <b>pcre2_match()</b> is one more than the highest numbered capturing
+pair that has been set (for example, 1 if there are no captures), zero if the
+vector of offsets is too small, or a negative error code for no match and other
+errors. The function arguments are:
+<pre>
+  <i>code</i>         Points to the compiled pattern
+  <i>subject</i>      Points to the subject string
+  <i>length</i>       Length of the subject string
+  <i>startoffset</i>  Offset in the subject at which to start matching
+  <i>options</i>      Option bits
+  <i>match_data</i>   Points to a match data block, for results
+  <i>mcontext</i>     Points to a match context, or is NULL
+</pre>
+A match context is needed only if you want to:
+<pre>
+  Set up a callout function
+  Set a matching offset limit
+  Change the heap memory limit
+  Change the backtracking match limit
+  Change the backtracking depth limit
+  Set custom memory management specifically for the match
+</pre>
+The <i>length</i> and <i>startoffset</i> values are code
+units, not characters. The length may be given as PCRE2_ZERO_TERMINATE for a
+subject that is terminated by a binary zero code unit. The options are:
+<pre>
+  PCRE2_ANCHORED          Match only at the first position
+  PCRE2_ENDANCHORED       Pattern can match only at end of subject
+  PCRE2_NOTBOL            Subject string is not the beginning of a line
+  PCRE2_NOTEOL            Subject string is not the end of a line
+  PCRE2_NOTEMPTY          An empty string is not a valid match
+  PCRE2_NOTEMPTY_ATSTART  An empty string at the start of the subject is not a valid match
+  PCRE2_NO_JIT            Do not use JIT matching
+  PCRE2_NO_UTF_CHECK      Do not check the subject for UTF validity (only relevant if PCRE2_UTF
+                           was set at compile time)
+  PCRE2_PARTIAL_HARD      Return PCRE2_ERROR_PARTIAL for a partial match even if there is a full match
+  PCRE2_PARTIAL_SOFT      Return PCRE2_ERROR_PARTIAL for a partial match if no full matches are found

+<P>
+This function is part of an experimental set of pattern conversion functions.
+It converts a foreign pattern (for example, a glob) into a PCRE2 regular
+expression pattern. Its arguments are:
+<pre>
+  <i>pattern</i>     The foreign pattern
+  <i>length</i>      The length of the input pattern or PCRE2_ZERO_TERMINATED
+  <i>options</i>     Option bits
+  <i>buffer</i>      Pointer to pointer to output buffer, or NULL
+  <i>blength</i>     Pointer to output length field
+  <i>cvcontext</i>   Pointer to a convert context or NULL
+</pre>
+The length of the converted pattern (excluding the terminating zero) is
+returned via <i>blength</i>. If <i>buffer</i> is NULL, the function just returns
+the output length. If <i>buffer</i> points to a NULL pointer, heap memory is
+obtained for the converted pattern, using the allocator in the context if
+present (or else <b>malloc()</b>), and the field pointed to by <i>buffer</i> is
+updated. If <i>buffer</i> points to a non-NULL field, that must point to a
+buffer whose size is in the variable pointed to by <i>blength</i>. This value is
+updated.
+</P>
+<P>
+The option bits are:
+<pre>
+  PCRE2_CONVERT_UTF                     Input is UTF
+  PCRE2_CONVERT_NO_UTF_CHECK            Do not check UTF validity
+  PCRE2_CONVERT_POSIX_BASIC             Convert POSIX basic pattern

+punctuation character whose code point is less than 256. The default is grave
+accent if running under Windows, otherwise backslash. The result of the
+function is zero for success or PCRE2_ERROR_BADDATA if the second argument is
