Sounds good. I’ll prepare a patch for Emacs.

It works in the sense of nothing going horribly wrong if you try to use
it. You can still edit Lua files but due to differences in the trees and
node names the experience is somewhat degraded.

Without having tried more than just swapping out the tree-sitter-lua.so
files it looks like it would be possible without much hassle.

I don’t think it’s worth any hassle though. The one I used is the same
as used by Neovim[1] and is already packaged for Alpine[2] and NixOS[3]
and is in the queue for Debian[4]. I’ll see about getting it added to
GNU Guix (which already has a number of other grammars).

Is working with both a prerequisite for inclusion or is there some other
reason to support them both? I’m not opposed but it doesn’t seem like an
important thing to do at this time.
