@pypas Yes please, it would be greatly appreciated!

Hey @noraj sorry, after taking a look at it couldn't figure out a nice solution for this one

[noraj]

@pypas I understand, no worry, this is not an easy task.

I just found https://github.com/crdx/docopt-compgen and I am able to generate something with haiti --help | tail +3 | docopt-compgen but it would work only for bash.

https://github.com/Infinidat/infi.docopt_completion would certainly work too since the help message is quiet language agnostic but this one works also for zsh. However it seems a bit abandoned.
