|
An optimized string type for unique names.
|
|
</brief_description>
|
|
<description>
|
|
[StringName]s are immutable strings designed for general-purpose representation of unique names (also called "string interning"). [StringName] ensures that only one instance of a given name exists (so two [StringName]s with the same value are the same object). Comparing them is much faster than with regular [String]s, because only the pointers are compared, not the whole strings.
|
|
You will usually just pass a [String] to methods expecting a [StringName] and it will be automatically converted, but you may occasionally want to construct a [StringName] ahead of time with [StringName] or, in GDScript, the literal syntax [code]&"example"[/code].
|
|
See also [NodePath], which is a similar concept specifically designed to store pre-parsed node paths.
|
|
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 [StringName] will evaluate to [code]false[/code] if it is empty ([code]StringName("")[/code]). Otherwise, a [StringName] will always evaluate to [code]true[/code].

[codeblocks]
|
|
[gdscript]

"move_local_x".capitalize() # Returns "Move Local X"
|

"move_local_x".Capitalize(); // Returns "Move Local X"
|
|
"sceneFile_path".Capitalize(); // Returns "Scene File Path"
|

<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].

<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"]]))

Returns [code]true[/code] if this string is a valid hexadecimal number. A valid hexadecimal number only contains digits or letters [code]A[/code] to [code]F[/code] (either uppercase or lowercase), and may be prefixed with a positive ([code]+[/code]) or negative ([code]-[/code]) sign.

If [param with_prefix] is [code]true[/code], the hexadecimal number needs to prefixed by [code]"0x"[/code] to be considered valid.

<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].
