Built-in string Variant type.
</brief_description>
<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 [code]n[/code] ([method countn], [method findn], [method replacen], etc.) are [b]case-insensitive[/b] (they make no distinction between uppercase and lowercase letters). Method variations prefixed with [code]r[/code] ([method rfind], [method rsplit], etc.) are reversed, and start from the end of the string, instead of the beginning.
[b]Note:[/b] In a boolean context, a string will evaluate to [code]false[/code] if it is empty ([code]""[/code]). Otherwise, a string will always evaluate to [code]true[/code].

<methods>
<method name="begins_with" qualifiers="const">
<return type="bool" />
<param index="0" name="text" type="String" />
<description>
Returns [code]true[/code] if the string begins with the given [param text]. See also [method ends_with].
</description>
</method>
<method name="bigrams" qualifiers="const">
<return type="PackedStringArray" />
<description>
Returns an array containing the bigrams (pairs of consecutive characters) of this string.
[codeblock]
print("Get up!".bigrams()) # Prints ["Ge", "et", "t ", " u", "up", "p!"]
[/codeblock]
</description>
</method>
<method name="bin_to_int" qualifiers="const">
<return type="int" />
<description>
Converts the string representing a binary number into an [int]. The string may optionally be prefixed with [code]"0b"[/code], and an additional [code]-[/code] prefix for negative numbers.
[codeblocks]
[gdscript]
print("101".bin_to_int()) # Prints 5
print("0b101".bin_to_int()) # Prints 5
print("-0b10".bin_to_int()) # Prints -2
[/gdscript]
[csharp]
GD.Print("101".BinToInt()); // Prints 5
GD.Print("0b101".BinToInt()); // Prints 5
GD.Print("-0b10".BinToInt()); // Prints -2
[/csharp]
[/codeblocks]
</description>
</method>
<method name="c_escape" qualifiers="const">
<return type="String" />
<description>
Returns a copy of the string with special characters escaped using the C language standard.
</description>
</method>
<method name="c_unescape" qualifiers="const">
<return type="String" />
<description>
Returns a copy of the string with escaped characters replaced by their meanings. Supported escape sequences are [code]\'[/code], [code]\"[/code], [code]\\[/code], [code]\a[/code], [code]\b[/code], [code]\f[/code], [code]\n[/code], [code]\r[/code], [code]\t[/code], [code]\v[/code].
[b]Note:[/b] Unlike the GDScript parser, this method doesn't support the [code]\uXXXX[/code] escape sequence.
</description>
</method>
<method name="capitalize" qualifiers="const">
<return type="String" />
<description>
Changes the appearance of the string: replaces underscores ([code]_[/code]) with spaces, adds spaces before uppercase letters in the middle of a word, converts all letters to lowercase, then converts the first one and each one following a space to uppercase.
[codeblocks]
[gdscript]

<method name="casecmp_to" qualifiers="const">
<return type="int" />
<param index="0" name="to" type="String" />
<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" and "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.
With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code].
To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to] and [method naturalnocasecmp_to].

<method name="format" qualifiers="const">
<return type="String" />
<param index="0" name="values" type="Variant" />
<param index="1" name="placeholder" type="String" default=""{_}"" />
<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 [param values] array will be used to replace one occurrence of the placeholder in order; If an element of [param values] 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"], "{}"))
print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))
[/codeblock]

<param index="0" name="to" type="String" />
<description>
Performs a [b]case-insensitive[/b], [i]natural order[/i] 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. Internally, lowercase characters are converted to uppercase for the comparison.
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 [code]["1", "2", "3", ...][/code], not [code]["1", "10", "2", "3", ...][/code].
With different string lengths, returns [code]1[/code] if this string is longer than the [param to] string, or [code]-1[/code] if shorter. Note that the length of empty strings is [i]always[/i] [code]0[/code].
To get a [bool] result from a string comparison, use the [code]==[/code] operator instead. See also [method nocasecmp_to] and [method casecmp_to].

String.num(3.141593, 3) # Returns "3.142"
String.num(3.14159300) # Returns "3.141593"
# Here, the last digit will be rounded up,
# which reduces the total digit count, since trailing zeros are removed:
String.num(42.129999, 5) # Returns "42.13"
# If `decimals` is not specified, the maximum number of significant digits is 14:
String.num(-0.0000012345432123454321) # Returns "-0.00000123454321"
