Arcanist, facebook's OSS code review tool
Need to use a tagged download.
That's not actually a tag; can we ask the upstream project to add a 1.0.1 git tag?
Per official documentation http://www.phabricator.com/docs/phabricator/article/Arcanist_User_Guide.html#installing-arcanist this is a head-only formula; rejecting for inclusion in core because of this (sorry.)
@adamv Why are head-only formulas not allowed?
@gnzlbg Because if upstream pushes a bad commit then it breaks the formula and we have no way of fixing it.
@mikemcquaid if upstream pushes a bad commit the formula remains correct, only the code/software is broken. That is upstream fault due to the bad commit. People interested in providing a workaround could do something about it (like temporarily checking out a given revision) but I think it is not worth it.
It's a poor user experience, regardless. That's why we don't support them in core.
Maybe one could support them in a different repo that one can tap like homebrew-heads or similar.
@mikemcquaid my bad :D
