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:
|
|
[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
|
|
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]

Return the current value for the specified section and key. If the section and/or the key do not exist, the method returns the value of the optional [i]default[/i] argument (and thus [code]NULL[/code] if not specified).

Load the config file specified as a parameter. The file's contents are parsed and loaded in the ConfigFile object from which the method was called. The return value is one of the OK, FAILED or ERR_* constants listed in [@Global Scope] (if the load was successful, it returns OK).

Save the contents of the ConfigFile object to the file specified as a parameter. The output file uses an INI-style structure.

The return value is one of the OK, FAILED or ERR_* constants listed in [@Global Scope] (if the save was successful, it returns OK).

Assign 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).
