Helper class to handle INI-style files.

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:
2017-10-13 20:52:12 +00:00
[codeblock]
[section]
some_key=42
string_example="Hello World!"
a_vector=Vector3( 1, 0, 2 )
[/codeblock]
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:
2017-09-12 20:42:36 +00:00
[codeblock]
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)
2017-10-13 20:52:12 +00:00
# Store a variable if and only if it hasn't been defined yet
2017-09-12 20:42:36 +00:00
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")
[/codeblock]

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. Returns one of the [code]OK[/code], [code]FAILED[/code] or [code]ERR_*[/code] constants listed in [@GlobalScope]. If the load was successful, the return value is [code]OK[/code].

Assigns a value to the specified key of the specified section. If the section and/or the key do not exist, they are created. Passing a [code]null[/code] value deletes the specified key if it exists, and deletes the section if it ends up empty once the key has been removed.
