Enable shell completions in Homebrew

[amoeba]

Homebrew formulae and casks can install shell completions at install-time and dbc has shell completions but we haven't enabled these in GoReleaser. We should.

• GoReleaser Docs: https://goreleaser.com/customization/homebrew_casks/
• Our tap: https://github.com/columnar-tech/homebrew-tap

Blocked on:

• Waiting for someone to submit dbc to homebrew/core (as a Formula, not Cask)

I think we have to hold off on this until dbc is in homebrew/core (as a formula, not cask). dbc's shell completions are generated dynamically and GoReleaser (and ultimately brew) needs these to be static files. See https://www.github.com/Homebrew/brew/issues/21482.

Our completions are static files though (even though we output them dynamically). We could update the goreleaser config to publish the completions in the meantime while it's still a cask?

Oh, you're right. I don't know why I wasn't seeing them when I write this issue. Yeah we can totally do that.

Same issue (I think)... I am trying to install the dbc cask via homebrew but it appears to reference shell completion files that don't exist. Thanks folks!

Hey @JavOrraca, apologies for that. Can you try running brew update and installing again with brew install dbc? We pushed an update that fixes the installation though you'll have to install completions manually afterwards with dbc completion.

Late reply @amoeba but really appreciate the guidance, your recommendation to install completions manually afterwards worked.
