Make argument required unless option is set

[tjhanley]

Is there a way to have something like this

cmd subcommand start [--branch BRANCH] [TICKET]

I want TICKET to be required unless --branch is specified

Hello!

This is currently impossible. But I consider to implement some option deps.

[tjhanley]

great. I'll keep an eye out for it.
