All versions of Emacs except emacs-minimal are built with tree-sitter support. But no grammar is added to propagated-inputs. Emacs version 29.1 ships with the following major modes:
typescript-ts-mode c-ts-mode c++-ts-mode java-ts-mode python-ts-mode css-ts-mode json-ts-mode csharp-ts-mode bash-ts-mode dockerfile-ts-mode cmake-ts-mode go-ts-mode yaml-ts-mode rust-ts-mode ruby-ts-mode In version 30.0.50 more added: html-ts-mode heex-ts-mode elixir-ts-mode lua-ts-mode Maybe grammars for these modes should be added to propagated-inputs? -- Best regards, Aleksandr Vityazev
