Use (eval-when-compile 'treesit) to save us from writing declare-function forms

Use (eval-when-compile 'treesit) to save us from writing declare-function forms

[Yuan Fu]

Some of my recent changes to c-ts-mode.el uses some more C treesit functions, and I (again) forgot to add their declare-function forms to c-ts-mode.el, and Andrea has to fix it for me. The main problem for me is that (I think) you don’t get warning for them unless you build a non-tree-sitter build of Emacs. So I’m prone to forgot about them. Also it’s a burden for anyone wanting to use tree-sitter functions.

treesit.el already has all the declare-function forms, how about we use (eval-when-compile 'treesit) in other files? I believe that should alleviate us from adding those declare-function forms in other files?

I want to ask because IIRC I proposed this a while back but there were objections, the details of which I forgot.

Hi Yuan,

I was not part of the discussion and I don't know what's the downside of
(eval-when-compile 'treesit), maybe another alternative would be to have
like a dedicated treesit-delcs.el to require where necessary?

I don't understand" c-ts-mode.el already does

  (require 'treesit)

So what would eval-when-compile add to that?
