To me, the most impressive use of tree-sitter was an iOS text editor that uses it to parse huge JSON files / mixed language files and highlight them in a very robust way. [0][1] I’m hoping tree-sitter becomes more common like LSP and Emacs can get exact highlighting and other tools with it… [0]: https://twitter.com/simonbs/status/1352697855845273600 https://twitter.com/simonbs/status/1352697855845273600 [1]: https://twitter.com/simonbs/status/1362492842141171720?s=21 https://twitter.com/simonbs/status/1362492842141171720?s=21

Yeah but I don't think LSP specs contain syntax-highlighting or semantic highlighting.

  LSP supports semantic highlighting: https://microsoft.github.io/language-server-protocol/specification#textDocument_semanticTokens https://microsoft.github.io/language-server-protocol/specifi... Though AIUI the basic syntax highlighting is done by the editor (e.g. VSCode uses Textmate grammar support).

FYI there is tree-sitter.el for Emacs.

Emacs does have a package to use tree-sitter [0]. I think emacs-lsp is aware of this highlighting backend and performs pretty well. (semantic highlighting is pretty slow for C++ with font-lock, with tree-sitter it's a breeze :)) [0]: https://github.com/ubolonton/emacs-tree-sitter https://github.com/ubolonton/emacs-tree-sitter

  Wait what? You mean to tell me that Emacs LSP already uses tree-sitter?
