- Commander will now throw an error when a command which takes no arguments or
options is invoked with
--helpor unknown arguments.
- Usage/help output for commands which contain flags will now contain the short
flag, for example,
-v, --verbose. #71
- Fixed ordering of flags in the "Unknown Arguments" help output of a command.
Flags have previously been stored in an un orderered set and thus upon
printing them back out their order was not persisted and a flag part such as
-usercan be printed as-usre. #78
- Support for Swift < 4.2 has been removed.
-
Added syntax for using array as a type with
Argumentinstead of usingVariadicArgument:command(Argument<[String]>("names")) { names in }
-
Added support for optional arguments and options, for example:
command(Argument<String?>("name")) { name in } command(Option<String?>("name", default: nil)) { name in }
-
Added support for using
--to signal that subsequent values should be treated as arguments instead of options.
