@samford I was trying out the new option for referencing casks/formula in a livecheck block. We may need to wait to use this feature across our cask taps as it looks like CI doesn't have the main cask repo tapped for the audit checks.

There is an issue open and plans to migrate homebrew-cask-versions to the homebrew-cask repo which would negate this anyway.

Per our discussion in the PR that introduced this part of the livecheck DSL, I made sure to document this in the related section of the brew livecheck documentation:

The referenced formula/cask should be in the same tap, as a reference to a formula/cask from another tap will generate an error if the user doesn’t already have it tapped.

I can see how using this feature makes sense for alternative casks like this one (where there are also new versions to check). It seems like it's technically possible to modify this repository's ci.yml GitHub Actions workflow to also tap homebrew/cask but I'm not familiar enough with the cask side of things to say whether this is appropriate/worthwhile.

However, though this may be possible on CI, I would prefer to avoid using this livecheck feature across taps. Anyone who happens to have homebrew/cask-versions tapped but not homebrew/cask (unlikely but seemingly possible?) would predictably get an error when running brew livecheck on this. While this change would ease maintainability of this livecheck block, it could break an otherwise-working check for some users.

From my perspective, this is something to revisit if/when these casks are merged into homebrew/cask but I would leave this as-is for now.

Yes, that totally makes sense. I had wrongly assumed that the main homebrew-cask tap would always be present. Thanks @samford
