Helper class to handle INI-style files.
|
|
</brief_description>
|
|
<description>
|
|
This helper class can be used to store [Variant] values on the filesystem using INI-style formatting. The stored values are indentified by a section and a key:
|
|
[codeblock]
|
|
[section]
|
|
some_key=42
|
|
string_example="Hello World!"
|
|
a_vector=Vector3( 1, 0, 2 )
|
|
[/codeblock]
|
|
The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly without accessing the filesystem.
|
|
The following example shows how to parse an INI-style file from the system, read its contents and store new values in it:
|
|
[codeblock]
|
|
var config = ConfigFile.new()
|
|
var err = config.load("user://settings.cfg")
|
|
if err == OK: # if not, something went wrong with the file loading
|
|
# Look for the display/width pair, and default to 1024 if missing
|
|
var screen_width = get_value("display", "width", 1024)
|
|
# Store a variable if and only if it hasn't been defined yet
|
|
if not config.has_section_key("audio", "mute"):
|
|
config.set_value("audio", "mute", false)
|
|
# Save the changes by overwriting the previous file
|
|
config.save("user://settings.cfg")
|
|
[/codeblock]

Loads the config file specified as a parameter. The file's contents are parsed and loaded in the ConfigFile object which the method was called on. Returns one of the [code]OK[/code], [code]FAILED[/code] or [code]ERR_*[/code] constants listed in [@GlobalScope]. If the load was successful, the return value is [code]OK[/code].

Saves the contents of the ConfigFile object to the file specified as a parameter. The output file uses an INI-style structure. Returns one of the [code]OK[/code], [code]FAILED[/code] or [code]ERR_*[/code] constants listed in [@GlobalScope]. If the load was successful, the return value is [code]OK[/code].

Assigns a value to the specified key of the the specified section. If the section and/or the key do not exist, they are created. Passing a [code]null[/code] value deletes the specified key if it exists, and deletes the section if it ends up empty once the key has been removed.
