I have a Fedora COPR (personal repo link). It's in the NeoVim wiki Fedora installation section. There's been interest in getting it into the main Fedora repo.
Koji (the Fedora build tool for all official packages) doesn't allow internet access during a build, though. And I can't figure out how to bundle the LuaRocks modules into the SRPM, or even exactly what I should bundle... any help would be appreciated.
My spec file can be found here, if it helps.
