GLib.OptionEntry

Fields

Name	Type	Access	Description
arg	GLib.OptionArg	r/w	The type of the option, as a GLib.OptionArg
arg_data	object	r/w	If the arg type is GLib.OptionArg.CALLBACK, then arg_data must point to a GLib.OptionArgFunc callback function, which will be called to handle the extra argument. Otherwise, arg_data is a pointer to a location to store the value, the required type of the location depends on the arg type:
arg_description	str	r/w	The placeholder to use for the extra argument parsed by the option in --help output. The arg_description is translated using the translate_func of the group, see GLib.OptionGroup.set_translation_domain().
description	str	r/w	the description for the option in --help output. The description is translated using the translate_func of the group, see GLib.OptionGroup.set_translation_domain().
flags	int	r/w	Flags from GLib.OptionFlags
long_name	str	r/w	The long name of an option can be used to specify it in a commandline as --long_name. Every option must have a long name. To resolve conflicts if multiple option groups contain the same long name, it is also possible to specify the option as --groupname-long_name.
short_name	int	r/w	If an option has a short name, it can be specified -short_name in a commandline. short_name must be a printable ASCII character different from ‘-’, or zero if the option has no short name.

Details

class GLib.OptionEntry

• GLib.OptionArg.NONE: bool

  • GLib.OptionArg.STRING: str

  • GLib.OptionArg.INT: int

  • GLib.OptionArg.FILENAME: str

  • GLib.OptionArg.STRING_ARRAY: str

  • GLib.OptionArg.FILENAME_ARRAY: str

  • GLib.OptionArg.DOUBLE: float

  If arg type is GLib.OptionArg.STRING or GLib.OptionArg.FILENAME, the location will contain a newly allocated string if the option was given. That string needs to be freed by the callee using GLib.free(). Likewise if arg type is GLib.OptionArg.STRING_ARRAY or GLib.OptionArg.FILENAME_ARRAY, the data should be freed using GLib.strfreev(). A GLib.OptionEntry struct defines a single option. To have an effect, they must be added to a GLib.OptionGroup with GLib.OptionContext.add_main_entries() or GLib.OptionGroup.add_entries().
