- Removed empty paragraphs in XML. - Consistently use bold style for "Example:", on a new line. - Fix usage of `[code]` when hyperlinks could be used (`[member]`, `[constant]`). - Fix invalid usage of backticks for inline code in BBCode. - Fix some American/British English spelling inconsistencies. - Other minor fixes spotted along the way, including typo fixes with codespell. - Don't specify `@GlobalScope` for `enum` and `constant`.

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.

|
<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" 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].

print("i" in "team") # Will print `false`.
|
|

|
|

<param index="0" name="what" type="String" />
|

<param index="1" name="from" type="int" default="0" />
|
|
<description>
|

<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 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"]]))

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.txt.".get_extension()) # "" (empty string)

|
|
<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]
|
|
print("i/am/example/string".get_slice("/", 2)) # Prints 'example'.

|
<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.
|

|
|
<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.

|
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.
|
|
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 [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 casecmp_to].

<description>
|
|
Converts a [float] to a string representation of a decimal number.
|
|
The number of decimal places can be specified with [param decimals]. If [param decimals] is [code]-1[/code] (default), decimal places will be automatically adjusted so that the string representation has 14 significant digits (counting both digits to the left and the right of the decimal point).
|
|
Trailing zeros are not included in the string. The last digit will be rounded and not truncated.
|
|
[b]Example:[/b]
|
|
[codeblock]
|
|
String.num(3.141593) # "3.141593"
|
|
String.num(3.141593, 3) # "3.142"
|
|
String.num(3.14159300) # "3.141593", no trailing zeros.
|
|
# Last digit will be rounded up here, which reduces total digit count since
|
|
# trailing zeros are removed:
|
|
String.num(42.129999, 5) # "42.13"
|
|
# If `decimals` is not specified, the total number of significant digits is 14:
|
|
String.num(-0.0000012345432123454321) # "-0.00000123454321"

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].

Converts the String (which is a character array) to ASCII/Latin-1 encoded [PackedByteArray] (which is an array of bytes). The conversion is faster compared to [method to_utf8_buffer], as this method assumes that all the characters in the String are ASCII/Latin-1 characters, unsupported characters are replaced with spaces.
