What should = tree-sitter.el do if libtree-sitter is not on the system, and = tree-sitter.c is not included in Emacs? Should we simply not include = tree-sitter.el? Is there existing build facility that can do that = (exclude tree-sitter.el when libtree-sitter is not found on system)? >=20 > I don't think I understand the problem: why would you need "not to > include" tree-sitter.el?

I guess some details of what bothers you are missing. Nothing in particular except the naive assumption that we won=E2=80=99t = provide functions that don=E2=80=99t work. I didn=E2=80=99t know that we = have quite a few *.el files that could potentially not work before. Do = you have some examples? Anyway, I can provide a function = tree-sitter-avaliable-p similar to native-compilation, that way a user = knows if he can use tree-sitter features. Yuan=
