Helper class to handle INI-style files.
</brief_description>
<description>
This helper class can be used to store [Variant] values on the filesystem using an INI-style formatting. The stored values as referenced by a section and a key. The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly with accessing the filesystem.
The following example shows how to parse a INI-style file from the system, read its contents and store new values in it:
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.

[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 it hasn't been defined yet
# 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
