We have a bunch of formulae in homebrew-core that are supposed to be updated simultaneously (like git and git-gui, python@3.9 and python-tk@3.9 and recently added libnghttp2 and nghttp2) and usually, we keep this requirement as a comment in formulae and check it manually during a PR review.

I propose adding a list (synced_versions_formulae.json) of such formulae to homebrew-core and an audit for checking those particular formulae have the same version.

The current version of synced_versions_formulae.json will look like this:

[
  ["cmake", "cmake-docs"],
  ["etl", "synfig"],
  ["fizz", "folly", "wangle", "watchman"],
  ["git", "git-credential-libsecret", "git-gui"],
  ["ilmbase", "openexr@2"],
  ["imath", "openexr"],
  ["libnghttp2", "nghttp2"],
  ["libqalculate", "qalculate-gtk"],
  ["mame", "rom-tools"],
  ["moarvm", "nqp", "rakudo"],
  ["python@3.10", "python-tk@3.10"],
  ["python@3.9", "python-tk@3.9"]
]

Great idea 👏🏻

There's also file-formula and libmagic. Just leaving a note here in case I miss synced_versions_formulae.json being added to Homebrew/core.

[Rylan12]

🎉 Love it, thanks!

Adding a list of such formulae to homebrew-core Homebrew/homebrew-core#87990

Review period ended.

Actually, before merging it, I need to sort out first, how to handle brew bump-formula-pr for such formulae first.

Can we either punt on bump-formula-pr or revert Homebrew/homebrew-core#87990? I'd either like this audit in place or the comments about syncing versions back.

Sorry about it 😞
Wasn't able to make a trivial change to brew-formula-pr straight away to handle this. I'll have another look at the PR this weekend and will try to come with some solution otherwise will revert that changes.

Just merge this PR as-is IMO. brew bump-formula-pr work can be a follow-up PR and/or help wanted issue.

And Homebrew/homebrew-core#89694 fixes the audit failure
