I guess I should have reached out sooner, communicating that I’m about to do 
it, but on the other hand I don’t want to just come in and talk about what I’m 
going to do and such and such, before I actually did anything. And my general 
understanding is that there aren’t much interest in integrating tree-sitter 
into the C core. So...

The code is at https://github.com/casouri/emacs, in the “ts” branch. The main 
things to look at are src/tree-sitter.c, lisp/tree-sitter.el, and 
doc/lispref/parsing.texi.

There is an on-going discussion about tree-sitter API in Emacs, starting at 
https://lists.gnu.org/archive/html/emacs-devel/2021-08/msg00246.html
