enum GLib::OptionArg

Overview

The #GOptionArg enum values determine which type of extra argument the options expect to find. If an option expects an extra argument, it can be specified in several ways; with a short option: -x arg, with a long option: --name arg or combined in a single argument: --name=arg.

Defined in:

lib/gi-crystal/src/auto/g_lib-2.0/g_lib.cr

Enum Members

None = 0_u32: No extra argument. This is useful for simple flags.
String = 1_u32: The option takes a UTF-8 string argument.
Int = 2_u32: The option takes an integer argument.
Callback = 3_u32: The option provides a callback (of type #GOptionArgFunc) to parse the extra argument.
Filename = 4_u32: The option takes a filename as argument, which will be in the GLib filename encoding rather than UTF-8.
StringArray = 5_u32: The option takes a string argument, multiple uses of the option are collected into an array of strings.
FilenameArray = 6_u32: The option takes a filename as argument, multiple uses of the option are collected into an array of strings.
Double = 7_u32: The option takes a double argument. The argument can be formatted either for the user's locale or for the "C" locale. Since 2.12
Int64 = 8_u32: The option takes a 64-bit integer. Like %G_OPTION_ARG_INT but for larger numbers. The number can be in decimal base, or in hexadecimal (when prefixed with 0x, for example, 0xffffffff). Since 2.12
