String
======

A built-in type for strings.

.. rst-class:: classref-introduction-group

Description
-----------

This is the built-in string Variant type (and the one used by GDScript). Strings may contain any number of Unicode characters, and expose methods useful for manipulating and generating strings. Strings are reference-counted and use a copy-on-write approach (every modification to a string returns a new **String**), so passing them around is cheap in resources.

Some string methods have corresponding variations. Variations suffixed with ``n`` (:ref:`countn()<class_String_method_countn>`, :ref:`findn()<class_String_method_findn>`, :ref:`replacen()<class_String_method_replacen>`, etc.) are **case-insensitive** (they make no distinction between uppercase and lowercase letters). Method variations prefixed with ``r`` (:ref:`rfind()<class_String_method_rfind>`, :ref:`rsplit()<class_String_method_rsplit>`, etc.) are reversed, and start from the end of the string, instead of the beginning.

To convert any :ref:`Variant<class_Variant>` to or from a string, see :ref:`@GlobalScope.str()<class_@GlobalScope_method_str>`, :ref:`@GlobalScope.str_to_var()<class_@GlobalScope_method_str_to_var>`, and :ref:`@GlobalScope.var_to_str()<class_@GlobalScope_method_var_to_str>`.

\ **Note:** In a boolean context, a string will evaluate to ``false`` if it is empty (``""``). Otherwise, a string will always evaluate to ``true``.

.. note::

	There are notable differences when using this API with C#. See :ref:`doc_c_sharp_differences` for more information.

.. _class_String_method_casecmp_to:

.. rst-class:: classref-method

:ref:`int<class_int>` **casecmp_to**\ (\ to\: :ref:`String<class_String>`\ ) |const| :ref:`🔗<class_String_method_casecmp_to>`

Performs a case-sensitive comparison to another string. Returns ``-1`` if less than, ``1`` if greater than, or ``0`` if equal. "Less than" and "greater than" are determined by the `Unicode code points <https://en.wikipedia.org/wiki/List_of_Unicode_characters>`__ of each string, which roughly matches the alphabetical order.

If the character comparison reaches the end of one string, but the other string contains more characters, then it will use length as the deciding factor: ``1`` will be returned if this string is longer than the ``to`` string, or ``-1`` if shorter. Note that the length of empty strings is always ``0``.

To get a :ref:`bool<class_bool>` result from a string comparison, use the ``==`` operator instead. See also :ref:`nocasecmp_to()<class_String_method_nocasecmp_to>`, :ref:`filecasecmp_to()<class_String_method_filecasecmp_to>`, and :ref:`naturalcasecmp_to()<class_String_method_naturalcasecmp_to>`.

    GD.Print("Potato".Find("t", 3)); // Prints 4
    GD.Print("Potato".Find("t", 5)); // Prints -1



\ **Note:** If you just want to know whether the string contains ``what``, use :ref:`contains()<class_String_method_contains>`. In GDScript, you may also use the ``in`` operator.

----

.. _class_String_method_findn:

.. rst-class:: classref-method

:ref:`int<class_int>` **findn**\ (\ what\: :ref:`String<class_String>`, from\: :ref:`int<class_int>` = 0\ ) |const| :ref:`🔗<class_String_method_findn>`

Returns the index of the **first** **case-insensitive** occurrence of ``what`` in this string, or ``-1`` if there are none. The starting search index can be specified with ``from``, continuing to the end of the string.

.. rst-class:: classref-item-separator

----

.. _class_String_method_format:

.. rst-class:: classref-method

:ref:`String<class_String>` **format**\ (\ values\: :ref:`Variant<class_Variant>`, placeholder\: :ref:`String<class_String>` = "{_}"\ ) |const| :ref:`🔗<class_String_method_format>`

Formats the string by replacing all occurrences of ``placeholder`` with the elements of ``values``.

\ ``values`` can be a :ref:`Dictionary<class_Dictionary>`, an :ref:`Array<class_Array>`, or an :ref:`Object<class_Object>`. Any underscores in ``placeholder`` will be replaced with the corresponding keys in advance. Array elements use their index as keys.

::

    # Prints "Waiting for Godot is a play by Samuel Beckett, and Godot Engine is named after it."
    var use_array_values = "Waiting for {0} is a play by {1}, and {0} Engine is named after it."
    print(use_array_values.format(["Godot", "Samuel Beckett"]))
    
    # Prints "User 42 is Godot."
    print("User {id} is {name}.".format({"id": 42, "name": "Godot"}))

Some additional handling is performed when ``values`` is an :ref:`Array<class_Array>`. If ``placeholder`` does not contain an underscore, the elements of the ``values`` array will be used to replace one occurrence of the placeholder in order; If an element of ``values`` is another 2-element array, it'll be interpreted as a key-value pair.

::

    # Prints "User 42 is Godot."
    print("User {} is {}.".format([42, "Godot"], "{}"))
    print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))

When passing an :ref:`Object<class_Object>`, the property names from :ref:`Object.get_property_list()<class_Object_method_get_property_list>` are used as keys.

::

    # Prints "Visible true, position (0, 0)"
    var node = Node2D.new()
    print("Visible {visible}, position {position}".format(node))

See also the :doc:`GDScript format string <../tutorials/scripting/gdscript/gdscript_format_string>` tutorial.

\ **Note:** Each replacement is done sequentially for each element of ``values``, **not** all at once. This means that if any element is inserted and it contains another placeholder, it may be changed by the next replacement. While this can be very useful, it often causes unexpected results. If not necessary, make sure ``values``'s elements do not contain placeholders.

::

    print("{0} {1}".format(["{1}", "x"]))           # Prints "x x"
    print("{0} {1}".format(["x", "{0}"]))           # Prints "x {0}"
    print("{a} {b}".format({"a": "{b}", "b": "c"})) # Prints "c c"
    print("{a} {b}".format({"b": "c", "a": "{b}"})) # Prints "{b} c"

\ **Note:** In C#, it's recommended to `interpolate strings with "$" <https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/interpolated>`__, instead.

.. rst-class:: classref-method

:ref:`int<class_int>` **naturalcasecmp_to**\ (\ to\: :ref:`String<class_String>`\ ) |const| :ref:`🔗<class_String_method_naturalcasecmp_to>`

Performs a **case-sensitive**, *natural order* comparison to another string. Returns ``-1`` if less than, ``1`` if greater than, or ``0`` if equal. "Less than" or "greater than" are determined by the `Unicode code points <https://en.wikipedia.org/wiki/List_of_Unicode_characters>`__ of each string, which roughly matches the alphabetical order.

When used for sorting, natural order comparison orders sequences of numbers by the combined value of each digit as is often expected, instead of the single digit's value. A sorted sequence of numbered strings will be ``["1", "2", "3", ...]``, not ``["1", "10", "2", "3", ...]``.

If the character comparison reaches the end of one string, but the other string contains more characters, then it will use length as the deciding factor: ``1`` will be returned if this string is longer than the ``to`` string, or ``-1`` if shorter. Note that the length of empty strings is always ``0``.

To get a :ref:`bool<class_bool>` result from a string comparison, use the ``==`` operator instead.

Splits the string using a ``delimiter`` and returns an array of the substrings, starting from the end of the string. The splits in the returned array appear in the same order as the original string. If ``delimiter`` is an empty string, each substring will be a single character.

If ``allow_empty`` is ``false``, empty strings between adjacent delimiters are excluded from the array.

If ``maxsplit`` is greater than ``0``, the number of splits may not exceed ``maxsplit``. By default, the entire string is split, which is mostly identical to :ref:`split()<class_String_method_split>`.

Splits the string using a ``delimiter`` and returns an array of the substrings. If ``delimiter`` is an empty string, each substring will be a single character. This method is the opposite of :ref:`join()<class_String_method_join>`.

If ``allow_empty`` is ``false``, empty strings between adjacent delimiters are excluded from the array.

.. _class_String_operator_lt_String:

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator <**\ (\ right\: :ref:`String<class_String>`\ ) :ref:`🔗<class_String_operator_lt_String>`

Returns ``true`` if the left **String** comes before ``right`` in `Unicode order <https://en.wikipedia.org/wiki/List_of_Unicode_characters>`__, which roughly matches the alphabetical order. Useful for sorting.

.. _class_String_operator_gt_String:

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator >**\ (\ right\: :ref:`String<class_String>`\ ) :ref:`🔗<class_String_operator_gt_String>`

Returns ``true`` if the left **String** comes after ``right`` in `Unicode order <https://en.wikipedia.org/wiki/List_of_Unicode_characters>`__, which roughly matches the alphabetical order. Useful for sorting.

.. _class_String_operator_gte_String:

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator >=**\ (\ right\: :ref:`String<class_String>`\ ) :ref:`🔗<class_String_operator_gte_String>`

Returns ``true`` if the left **String** comes after ``right`` in `Unicode order <https://en.wikipedia.org/wiki/List_of_Unicode_characters>`__, which roughly matches the alphabetical order, or if both are equal.

.. _class_String_operator_idx_int:

.. rst-class:: classref-operator

:ref:`String<class_String>` **operator []**\ (\ index\: :ref:`int<class_int>`\ ) :ref:`🔗<class_String_operator_idx_int>`

Returns a new **String** that only contains the character at ``index``. Indices start from ``0``. If ``index`` is greater or equal to ``0``, the character is fetched starting from the beginning of the string. If ``index`` is a negative value, it is fetched starting from the end. Accessing a string out-of-bounds will cause a run-time error, pausing the project execution if run from the editor.
