So far I am only working on font locking, and have NO experience with
font locking in Emacs or with tree-sitter. With that in mind, using the
starter-guide file, the html-manual, an existing grammar, and examples
from python mode, I was able to get a working prototype in clojure-mode
in 1 day. I think that speaks to the quality of the documentation!
The treesit-explore-mode is a really great tool for implementing the
syntax highlighting as well. It is a real treat to work with.
Here is how I ended up using a function to fontify the symbols the way I
needed to, in case you are curious:
https://github.com/dannyfreeman/clojure-mode/blob/513403c5e97330b65d024e2e904c165021540480/clojure-ts-mode.el#L162-L177
Right now that entire file is a rough proof of concept. There is a lot
more work that needs to be done before it's ready for the general
public.
