[bard]

To try: M-x customize-variable RET run-command-completion-method RET and choose "completing-read".

Fixes: #3

Thank you! Seems to work fine 👍

Personally I would default to completing-read, this way ivy and helm will be automatically used when their mode is enabled. Though if you use specific features of them you could check for the mode (at runtime) instead of using featurep. For example I have helm and ivy installed but usually prefer to use default completion with Selectrum.

I just did the former, but the latter seems like an even better idea, I'll do that instead.
