Summary: Ref T13098. Historically, Phabricator was split into three parts: - Phabricator, the server. - Arcanist, the client. - libphutil, libraries shared between the client and server. One imagined use case for this was that `libphutil` might become a general-purpose library that other projects would use. However, this didn't really happen, and it seems unlikely to at this point: Phabricator has become a relatively more sophisticated application platform; we didn't end up seeing or encouraging much custom development; what custom development there is basically embraces all of Phabricator since there are huge advantages to doing so; and a general "open source is awful" sort of factor here in the sense that open source users often don't have goals well aligned to our goals. Turning "arc" into a client platform and building package management solidify us in this direction of being a standalone platform, not a standalone utility library. Phabricator also depends on `arcanist/`. If it didn't, there would be a small advantage to saying "shared code + client for client, shared code + server for server", but there's no such distinction and it seems unlikely that one will ever exist. Even if it did, I think this has little value. Nowadays, I think this separation has no advantages for us and one significant cost: it makes installing `arcanist` more difficult for end-users. This will need some more finesssing (Phabricator will need some changes for compatibility, and a lot of stuff that still says "libphutil" or "phutil" may eventually want to say "arcanist"), and some stuff (like xhpast) is probably straight-up broken right now and needs some tweaking, but I don't anticipate any major issues here. There was never anything particularly magical about libphutil as a separate standalone library. Test Plan: Ran `arc`, it gets about as far as it did before.

= Building = Normally, you can build `xhpast` by running `make`, which will create a binary in this directory: xhpast/ $ make You can run `make install` to copy that binary to the right place in libphutil so that libphutil, Phabricator, Diviner, etc., can use xhpast. If you are developing `xhpast`, you need to `make parser scanner xhpast` instead to regenerate the parser and scanner: xhpast/ $ make parser scanner xhpast We ship the generated parser and scanner and do not rebuild them by default to prevent users from needing to install flex and bison and fiddle around with flex versions.
