#12Interesting, given that Google and Facebook [2], at least, eventually moved to have their repositories offered via Mercurial interface, instead of git. I also would expect that Github eventually will also offer mercurial repos. p.s. And let's not talk about abomination that is GitLFS (starting from the fact that it requires separate subcommand).

FB/Meta replaced Mercurial with Sapling which is git-compatible: https://engineering.fb.com/2022/11/15/open-source/sapling-so... Mercurial is over.
Microsoft hired a git maintainer to improve large repo performance and so it's better than it was.

> I also would expect that Github eventually will also offer mercurial repos. How come? That seems highly unlikely to me, especially when you consider that one of their larger competitors (Bitbucket) had Mercurial support for a long time and then removed it.

#14Earlier quoted context omitted.
That’s 2014 vintage. Is it still true?
Yup! In fact Meta’s implementation is open sourced as Sapling SCM and includes both Mercurial and Git support[1]. Internally the main repository use Mercurial although I believe a few legacy projects still use git. [1] https://sapling-scm.com/

#15i kind of wonder why there has never been an "hghub", given that i've always liked hg rather than git. but i guess it is the torvalds connection?

I believe Meta’s implementation includes server components (Mononoke) that were not open-sourced, or at least not buildable without closed-source dependencies. Same with Microsoft’s fork of git that relies on a virtual filesystem, but that one is open-sourced, if for Windows, not Linux.

I just don't think there is good RoI for implementing Mercurial support. It really isn't about the interface (which I think most people agree hg is better than git). It's just the network effect: most projects use git so everybody learns git and they don't want to learn another tool even if it's better in some ways. At the end of the day, once you pay a higher upfront cost to learn the ~5 git invocations you need, your daily productivity between using git and hg is probably the same.
Google and Facebook is different: they have a unique use-case and scale, and massive internal tooling teams supporting their use-cases. Also, as an employee, you're probably more open to different VCS systems because if you learn hg at Facebook, you're learning it on company time whereas if you learn for an open source project, you're learning it on your time.
