+Of the shorthand classes that are supported, they are all ASCII-based, even
|
|
|
|
+when compiling in Unicode mode. This is for the sake of general performance and
|
|
|
|
+simplicity, as there are thousands of Unicode codepoints which would qualify as
|
|
|
|
+either a digit, space, or word character which could be irrelevant depending on
|
|
|
|
+what is being matched.
|
|
|
|

|
|
|
|
+Here are the shorthand class equivalencies:
|
|
|
|
+ \d: [0-9]
|
|
|
|
+ \s: [\t\n\f\r ]
|
|
|
|
+ \w: [0-9A-Z_a-z]
|
|
|
|
+
|
|
|
|
+If you need your own shorthands, you can compose strings together like so:
|
|
|
|
+ MY_HEX :: "[0-9A-Fa-f]"
|
|
|
|
+ PATTERN :: MY_HEX + "-" + MY_HEX
|
|
|
|
+
|
|
|
|
+The compiler will handle turning multiple identical classes into references to
|
|
|
|
+the same set of matching runes, so there's no penalty for doing it like this.
