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_get_section_keys:
|
|
|
|
- :ref:`StringArray<class_stringarray>` **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:`StringArray<class_stringarray>` **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:
|
|
|
|
- Error **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:
|
|
|
|
- Error **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).
