@bartekpacia Single issue also works for me 👍🏼 I didn't want to pressure you (or anyone else) to get it all done in one shot 😁

@bartekpacia I dont understand. The "generate-completion" is a hidden command in urfave/cli/v3. So if user invokes

myapp generate-completion zsh

It will output the zsh completion script which can be copied by user and sourced.

@dearchap Thank you for pointing it out – I wasn't aware of it.

It doesn't look like this feature is documented anywhere yet – but this may be actually a good thing, because v3 is at alpha, so we could:

• rename default name to completion (to match Cobra - let users use their muscle memory)
• make the completion script not require $PROG to be set – use CLI app name instead.
• write docs! :D

SGTM 👍🏼

SGTM 👍🏼

WDYT about creating targeted issues for each of these?

[bartekpacia]

@meatballhat I think all these changes should be ideally made in a single PR, to keep them atomic and easy to revert - so a single issue to track them is enough for me.

That said if you disagree I can of course create the issues.
