  30. Description
  31. -----------
  32. 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.
  33. The following example shows how to parse a INI-style file from the system, read its contents and store new values in it:
  34. ::
  35. var config = ConfigFile.new()
  36. var err = config.load("user://settings.cfg")
  37. if err == OK: # if not, something went wrong with the file loading
  38. # Look for the display/width pair, and default to 1024 if missing
  39. var screen_width = get_value("display", "width", 1024)
  40. # Store a variable if and only it hasn't been defined yet
  41. if not config.has_section_key("audio", "mute"):
  42. config.set_value("audio", "mute", false)
  43. # Save the changes by overwriting the previous file
  44. config.save("user://settings.cfg")
  45. Member Function Description
  46. ---------------------------
  47. .. _class_ConfigFile_get_section_keys:
  48. - :ref:`StringArray<class_stringarray>` **get_section_keys** **(** :ref:`String<class_string>` section **)** const
  49. Return an array of all defined key identifiers in the specified section.
  50. .. _class_ConfigFile_get_sections:
  51. - :ref:`StringArray<class_stringarray>` **get_sections** **(** **)** const
  52. Return an array of all defined section identifiers.
  53. .. _class_ConfigFile_get_value:
  54. - :ref:`Variant<class_variant>` **get_value** **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key, :ref:`Variant<class_variant>` default=NULL **)** const
  55. 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).
  56. .. _class_ConfigFile_has_section:
  57. - :ref:`bool<class_bool>` **has_section** **(** :ref:`String<class_string>` section **)** const
  58. Check if the specified section exists.
  59. .. _class_ConfigFile_has_section_key:
  60. - :ref:`bool<class_bool>` **has_section_key** **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key **)** const
  61. Check if the specified section-key pair exists.
  62. .. _class_ConfigFile_load:
  63. - Error **load** **(** :ref:`String<class_string>` path **)**
  64. 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).
  65. .. _class_ConfigFile_save:
  66. - Error **save** **(** :ref:`String<class_string>` path **)**
  67. Save the contents of the ConfigFile object to the file specified as a parameter. The output file uses an INI-style structure.
  68. 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).
  69. .. _class_ConfigFile_set_value:
  70. - void **set_value** **(** :ref:`String<class_string>` section, :ref:`String<class_string>` key, :ref:`Variant<class_variant>` value **)**
  71. 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).
