Hi folks, Browsing the customization settings can raise warnings for tree-sitter modes that are not in use. Recipe: 0. Build Emacs with tree-sitter support, but don't install associated language grammars 1. Emacs -Q 2. M-x customize-browse 3. Expand the "Programming" group 4. Expand the "Languages" group You will see a warning for any installed tree-sitter modes whose grammars are not installed. Emacs ships with several such modes, e.g. ruby-ts-mode, elixir-ts-mode, heex-ts-mode, php-ts-mode, and lua-ts-mode. The warnings are surprising, since I'm just browsing customization settings, and not even settings specific to those modes. I haven't tried to enable any of these modes so far. I think most users will not preemptively install language grammars for every installed tree-sitter mode (especially as more such modes are added), so browsing customization settings should not raise warnings like this. Should these libraries really make noise like this when they are unintentionally loaded by the user? Cheers, and thanks!
