Built-in string class.
</brief_description>
<description>
This is the built-in string class (and the one used by GDScript). It supports Unicode and provides all necessary means for string handling. Strings are reference-counted and use a copy-on-write approach, so passing them around is cheap in resources.

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 [code]to[/code] string or [code]-1[/code] if the "base" string is shorter than the [code]to[/code] 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 [code]to[/code] 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].

<return type="int" />
<argument index="0" name="what" type="String" />
<argument index="1" name="from" type="int" default="0" />
<description>
Finds the first occurrence of a substring. Returns the starting position of the substring or [code]-1[/code] if not found. Optionally, the initial search index can be passed.
[b]Note:[/b] If you just want to know whether a string contains a substring, use the [code]in[/code] operator as follows:
[codeblock]
# Will evaluate to `false`.
if "i" in "team":
pass
[/codeblock]
</description>
</method>
<method name="find_last">
<return type="int" />

</method>
<method name="format">
<return type="String" />
<argument index="0" name="values" type="Variant" />
<argument index="1" name="placeholder" type="String" default="&quot;{_}&quot;" />
<description>
Formats the string by replacing all occurrences of [code]placeholder[/code] with the elements of [code]values[/code].
[code]values[/code] can be a [Dictionary] or an [Array]. Any underscores in [code]placeholder[/code] 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 [code]values[/code] is an array. If [code]placeholder[/code] 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"], "{}"))
print("User {id} is {name}.".format([["id", 42], ["name", "Godot"]]))
[/codeblock]

If the string is a valid file path, returns the full file path without the extension.
</description>
</method>
<method name="get_extension">
<return type="String" />
<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]
print("/path/to/file.txt".get_extension()) # "txt"
print("file.txt".get_extension()) # "txt"
print("file.sample.txt".get_extension()) # "txt"
print(".txt".get_extension()) # "txt"
print("file.txt.".get_extension()) # "" (empty string)
print("file.txt..".get_extension()) # "" (empty string)
print("txt".get_extension()) # "" (empty string)
print("".get_extension()) # "" (empty string)

<argument index="1" name="slice" type="int" />
<description>
Splits a string using a [code]delimiter[/code] and returns a substring at index [code]slice[/code]. 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.
Example:
[codeblock]
print("i/am/example/string".get_slice("/", 2)) # Prints 'example'.
[/codeblock]
</description>
</method>
<method name="hash">
<return type="int" />
<description>
Returns the 32-bit hash value representing the string's contents.
[b]Note:[/b] [String]s with equal content will always produce identical hash values. However, the reverse is not true. Returning identical hash values does [i]not[/i] imply the strings are equal, because different strings can have identical hash values due to hash collisions.
</description>
</method>
<method name="hex_to_int">
<return type="int" />
<description>
Converts a string containing a hexadecimal number into an integer. Hexadecimal strings are expected to be prefixed with "[code]0x[/code]" otherwise [code]0[/code] is returned.

<argument index="0" name="to" type="String" />
2021-02-13 14:13:58 +00:00
<description>
Performs a case-insensitive [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 will be converted to uppercase during the comparison.
2021-02-13 14:13:58 +00:00
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].
[b]Behavior with different string lengths:[/b] Returns [code]1[/code] if the "base" string is longer than the [code]to[/code] string or [code]-1[/code] if the "base" string is shorter than the [code]to[/code] 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 [code]to[/code] 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 casecmp_to].

<description>
Splits the string by a [code]delimiter[/code] string and returns an array of the substrings, starting from right.
The splits in the returned array are sorted in the same order as the original string, from left to right.
If [code]allow_empty[/code] 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 [code]maxsplit[/code] is specified, it defines the number of splits to do from the right up to [code]maxsplit[/code]. The default value of 0 means that all items are split, thus giving the same result as [method split].

[codeblock]
var some_string = "One,Two,Three,Four"
var some_array = some_string.split(",", true, 1)
print(some_array.size()) # Prints 2
print(some_array[0]) # Prints "One"
print(some_array[1]) # Prints "Two,Three,Four"
