Description
-----------

This helper class can be used to store :ref:`Variant<class_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
---------------------------

.. _class_ConfigFile_erase_section:

- void  **erase_section**  **(** :ref:`String<class_string>` section  **)**

.. _class_ConfigFile_get_section_keys:

- :ref:`PoolStringArray<class_poolstringarray>`  **get_section_keys**  **(** :ref:`String<class_string>` section  **)** const

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

.. _class_ConfigFile_get_sections:

- :ref:`PoolStringArray<class_poolstringarray>`  **get_sections**  **(** **)** const

Return an array of all defined section identifiers.

.. _class_ConfigFile_get_value:

- :ref:`Variant<class_variant>`  **get_value**  **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key, :ref:`Variant<class_variant>` default=null  **)** const

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).

.. _class_ConfigFile_has_section:

- :ref:`bool<class_bool>`  **has_section**  **(** :ref:`String<class_string>` section  **)** const

Check if the specified section exists.

.. _class_ConfigFile_has_section_key:

- :ref:`bool<class_bool>`  **has_section_key**  **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key  **)** const

Check if the specified section-key pair exists.

.. _class_ConfigFile_load:

- :ref:`int<class_int>`  **load**  **(** :ref:`String<class_string>` path  **)**

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 :ref:`@Global Scope<class_@global scope>` (if the load was successful, it returns OK).

.. _class_ConfigFile_save:

- :ref:`int<class_int>`  **save**  **(** :ref:`String<class_string>` path  **)**

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 :ref:`@Global Scope<class_@global scope>` (if the save was successful, it returns OK).

.. _class_ConfigFile_set_value:

- void  **set_value**  **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key, :ref:`Variant<class_variant>` value  **)**

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).
