<brief_description>
|
|
A built-in type for strings.
|
|
</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]. The [code]not[/code] operator cannot be used. Instead, [method is_empty] should be used to check for empty strings.

<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], [method filecasecmp_to], and [method naturalcasecmp_to].

<description>
|
|
Returns a string with [param chars] characters erased starting from [param position]. If [param chars] goes beyond the string's length given the specified [param position], fewer characters will be erased from the returned string. Returns an empty string if either [param position] or [param chars] is negative. Returns the original string unmodified if [param chars] is [code]0[/code].

Like [method naturalcasecmp_to] but prioritises strings that begin with periods ([code].[/code]) and underscores ([code]_[/code]) before any other character. Useful when sorting folders or file names.

<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"]]))

Splits the string using a [param delimiter] and returns the substring at index [param slice]. Returns the original string if [param delimiter] does not occur in the string. Returns an empty string if the [param slice] does not exist.

Performs a [b]case-sensitive[/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.
|
|
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 naturalnocasecmp_to], [method filecasecmp_to], and [method nocasecmp_to].

Converts a [float] to a string representation of a decimal number, with the number of decimal places specified in [param decimals].
|
|
If [param decimals] is [code]-1[/code] as by default, the string representation may only have up to 14 significant digits, with digits before the decimal point having priority over digits after.

Trailing zeros are not included in the string. The last digit is rounded, not truncated.

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:

|
|
Splits the string using a [param 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 [param delimiter] is an empty string, each substring will be a single character.
|
|
If [param allow_empty] is [code]false[/code], empty strings between adjacent delimiters are excluded from the array.
|
|
If [param maxsplit] is greater than [code]0[/code], the number of splits may not exceed [param maxsplit]. By default, the entire string is split, which is mostly identical to [method split].

Splits the string using a [param delimiter] and returns an array of the substrings. If [param delimiter] is an empty string, each substring will be a single character. This method is the opposite of [method join].

If [param allow_empty] is [code]false[/code], empty strings between adjacent delimiters are excluded from the array.

If [param maxsplit] is greater than [code]0[/code], the number of splits may not exceed [param maxsplit]. By default, the entire string is split.

// C#'s `Split()` does not support the `maxsplit` parameter.

[b]Note:[/b] If you only need one substring from the array, consider using [method get_slice] which is faster. If you need to split strings with more complex rules, use the [RegEx] class instead.

Returns a new [String] that only contains the character at [param index]. Indices start from [code]0[/code]. If [param index] is greater or equal to [code]0[/code], the character is fetched starting from the beginning of the string. If [param 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.
