How to alias subcommand and option?

[foonathan]

Is it possible to have a subcommand and an option do the same thing?

Consider git, all the following commands get you the version:

git -v
git --version
git version

I can of course add a version subcommand together with a -v/--version option and have them manually do the same thing, but is there a more elegant way?

Nevermind, I found .alias() which appears to do the job. Although it's a bit weird if it is listed as --version under a subcommand.

Usually what has been done in the past in cases where this is required is to add an option or flag with -v and --version and then a separate subcommand that has a callback that does the same thing as the option. If it is complicated then the callback versions of the option/flag can be used and the same callback used in the subcommand callback. This is a little "cleaner" than making a subcommand alias of "--version"

Yeah, I guess that makes sense as well.
