<description>
Changes the case of some letters.

</method>
<method name="casecmp_to" qualifiers="const">
<return type="int" />

<description>
Performs a case-sensitive comparison to another string. Returns [code]-1[/code] if less than, [code]1[/code] if greater than, or [code]0[/code] if equal. "less than" or "greater than" are determined by the [url=https://en.wikipedia.org/wiki/List_of_Unicode_characters]Unicode code points[/url] of each string, which roughly matches the alphabetical order.
[b]Behavior with different string lengths:[/b] Returns [code]1[/code] if the "base" string is longer than the [param to] string or [code]-1[/code] if the "base" string is shorter than the [param to] string. Keep in mind this length is determined by the number of Unicode codepoints, [i]not[/i] the actual visible characters.
[b]Behavior with empty strings:[/b] Returns [code]-1[/code] if the "base" string is empty, [code]1[/code] if the [param to] string is empty or [code]0[/code] if both strings are empty.
To get a boolean result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to] and [method naturalnocasecmp_to].

Returns the index of the [b]first[/b] case-sensitive occurrence of the specified string in this instance, or [code]-1[/code]. Optionally, the starting search index can be specified, continuing to the end of the string.
[b]Note:[/b] If you just want to know whether a string contains a substring, use the [code]in[/code] operator as follows:

[gdscript]

<return type="String" />
<param index="0" name="values" type="Variant" />
<param index="1" name="placeholder" type="String" default="&quot;{_}&quot;" />
<description>
Formats the string by replacing all occurrences of [param placeholder] with the elements of [param values].
[param values] can be a [Dictionary] or an [Array]. Any underscores in [param placeholder] will be replaced with the corresponding keys in advance. Array elements use their index as keys.
[codeblock]
# 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"}))
[/codeblock]
Some additional handling is performed when [param values] is an array. If [param placeholder] does not contain an underscore, the elements of the array will be used to replace one occurrence of the placeholder in turn; If an array element is another 2-element array, it'll be interpreted as a key-value pair.
[codeblock]
# Prints: User 42 is Godot.
print("User {} is {}.".format([42, "Godot"], "{}"))

<description>
Returns the extension without the leading period character ([code].[/code]) if the string is a valid file name or path. If the string does not contain an extension, returns an empty string instead.
[codeblock]

<description>
Splits a string using a [param delimiter] and returns a substring at index [param slice]. Returns an empty string if the index doesn't exist.
This is a more performant alternative to [method split] for cases when you need only one element from the array at a fixed index.
[b]Example:[/b]

[/codeblock]
</description>
</method>
<method name="get_slice_count" qualifiers="const">

<method name="get_slicec" qualifiers="const">
<return type="String" />
<param index="0" name="delimiter" type="int" />
<param index="1" name="slice" type="int" />
<description>
Splits a string using a Unicode character with code [param delimiter] and returns a substring at index [param slice]. Returns an empty string if the index doesn't exist.
This is a more performant alternative to [method split] for cases when you need only one element from the array at a fixed index.

<method name="hex_to_int" qualifiers="const">

<description>
Converts a string containing a hexadecimal number into an integer. Hexadecimal strings can either be prefixed with [code]0x[/code] or not, and they can also start with a [code]-[/code] before the optional prefix.
[codeblocks]
[gdscript]
print("0xff".hex_to_int()) # Prints "255".

</description>
</method>
<method name="indent" qualifiers="const">
<return type="String" />
<param index="0" name="prefix" type="String" />
<description>
Returns a copy of the string with lines indented with [param prefix].
For example, the string can be indented with two tabs using [code]"\t\t"[/code], or four spaces using [code]" "[/code]. The prefix can be any string so it can also be used to comment out strings with e.g. [code]"# "[/code]. See also [method dedent] to remove indentation.
[b]Note:[/b] Empty lines are kept empty.

Internally, lowercase characters will be converted to uppercase during the comparison.
When used for sorting, natural order comparison will order suites of numbers as expected by most people. If you sort the numbers from 1 to 10 using natural order, you will get [code][1, 2, 3, ...][/code] instead of [code][1, 10, 2, 3, ...][/code].

Keep in mind this length is determined by the number of Unicode codepoints, [i]not[/i] the actual visible characters.
[b]Behavior with empty strings:[/b] Returns [code]-1[/code] if the "base" string is empty, [code]1[/code] if the [param to] string is empty or [code]0[/code] if both strings are empty.

<description>
Splits the string by a [param delimiter] string and returns an array of the substrings, starting from right. If [param delimiter] is an empty string, each substring will be a single character.
The splits in the returned array are sorted in the same order as the original string, from left to right.

If [param maxsplit] is specified, it defines the number of splits to do from the right up to [param maxsplit]. The default value of 0 means that all items are split, thus giving the same result as [method split].
[b]Example:[/b]

<description>
Splits the string by a [param delimiter] string and returns an array of the substrings. The [param delimiter] can be of any length. If [param delimiter] is an empty string, each substring will be a single character.
If [param allow_empty] is [code]true[/code], and there are two adjacent delimiters in the string, it will add an empty string to the array of substrings at this position.
If [param maxsplit] is specified, it defines the number of splits to do from the left up to [param maxsplit]. The default value of [code]0[/code] means that all items are split.
If you need only one element from the array at a specific index, [method get_slice] is a more performant option.
