ConfigFile¶

Helper class to handle INI-style files.

Description¶

This helper class can be used to store Variant values on the filesystem using INI-style formatting. The stored values are identified by a section and a key:

[section]
some_key=42
string_example="Hello World!"
a_vector=Vector3( 1, 0, 2 )

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:

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 = config.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")

Keep in mind that section and property names can’t contain spaces. Anything after a space will be ignored on save and on load.

ConfigFiles can also contain manually written comment lines starting with a semicolon (;). Those lines will be ignored when parsing the file. Note that comments will be lost when saving the ConfigFile. This can still be useful for dedicated server configuration files, which are typically never overwritten without explicit user action.

Method Descriptions¶

void erase_section ( String section )

Deletes the specified section along with all the key-value pairs inside. Raises an error if the section does not exist.

void erase_section_key ( String section, String key )

Deletes the specified key in a section. Raises an error if either the section or the key do not exist.

PoolStringArray get_section_keys ( String section ) const

Returns an array of all defined key identifiers in the specified section. Raises an error and returns an empty array if the section does not exist.

PoolStringArray get_sections ( ) const

Returns an array of all defined section identifiers.

Variant get_value ( String section, String key, Variant default=null ) const

Returns the current value for the specified section and key. If either the section or the key do not exist, the method returns the fallback default value. If default is not specified or set to null, an error is also raised.

bool has_section ( String section ) const

Returns true if the specified section exists.

bool has_section_key ( String section, String key ) const

Returns true if the specified section-key pair exists.

Error load ( String path )

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.
