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:

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")

Member Function Description

Return an array of all defined key identifiers in the specified section.

Return an array of all defined section identifiers.

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 default argument (and thus NULL if not specified).

Check if the specified section exists.

Check if the specified section-key pair exists.

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 NULL value deletes the specified key if it exists (and deletes the section if it ends up empty once the key has been removed).
