tsi.el VS elisp-tree-sitter

I've been building out tsi.el - an emacs minor mode which performs indentation based on a CST returned by tree-sitter. please give it a try if you haven't already, and if you have tried it and it did not meet your needs then I'd love to hear why not!

I'd really like to see something that combines the conciseness of SMIE's rule-based indentation system with tree-sitter's richer grammar. There are a couple of projects that I'm looking at, such as https://codeberg.org/FelipeLema/tree-sitter-indent.el and https://github.com/orzechowskid/tsi.el).

;; use our derived mode for tsx files (add-to-list 'auto-mode-alist '("\.tsx\'" . typescriptreact-mode)) ;; by default, typescript-mode is mapped to the treesitter typescript parser ;; use our derived mode to map .tsx -> typescriptreact-mode -> treesitter tsx (add-to-list 'tree-sitter-major-mode-language-alist '(typescriptreact-mode . tsx)) ;; https://github.com/orzechowskid/tsi.el/ ;; great tree-sitter-based indentation for typescript/tsx, css, json (quelpa '(tsi :fetcher github :repo "orzechowskid/tsi.el")) (add-hook 'typescript-mode-hook (lambda () (tsi-typescript-mode 1)))) ```

what are your specific problems? lsp, typescript-mode, and tree-sitter-mode together give me 90% of what I need. I fixed JSX/TSX indentation with a little tool I built (which I should really get around to publishing some day). I'm extremely happy with this setup and use it every day on professional and personal projects.

Look at the original integration project https://github.com/emacs-tree-sitter/elisp-tree-sitter, before it was done inside Emacs 29+.

When tree-sitter is available you may extend expand-region with this one one https://github.com/emacs-tree-sitter/elisp-tree-sitter/issues/20 Works very nice for me. But simple matching pairs should be handled well by expand-region alone

That said, if you want a more complete experience with tree-sitter right now, there’s a 3rd party implementation with support for a lot more languages, and also automatically downloads all supported grammars. It’s available here: https://github.com/emacs-tree-sitter/elisp-tree-sitter

Just like there are multiple LSP implementations for emacs (lsp-mode, eglot, lsp-bridge), there are multiple tree-sitter implementations. The one recently included in emacs was never a standalone package, I believe (correct me if that’s wrong), but was created with the purpose of being included in emacs. You will need melpa to download the linked elisp-tree-sitter package (https://github.com/emacs-tree-sitter/elisp-tree-sitter), but not the built in one.

How am I going to even use the built-in one? I was using elisp-tree-sitter. I know I have to add grammar for different languages, but how? I have been searching for a while and still have no clue.

from github README.rst "Emacs package that provides a standardized framework for manipulating and navigating your source code using tree sitter's concrete syntax tree " -> https://github.com/mickeynp/combobulate

https://www.spacemacs.org/ with https://github.com/emacs-tree-sitter/elisp-tree-sitter then write a iterator/loop query for language(s) editing per https://tree-sitter.github.io/tree-sitter/syntax-highlightin...

tad less installation heavy (sorta) but also makes use of tree-sitter syntax queries : https://www.lunarvim.org (neovim with treesitter syntax)

Alternative examples / takes (per user interface):

However, if you want to use tree-sitter today, there is the tree-sitter package which enables tree-sitter syntax highlighting in a number of popular major modes. I’ve been using it for about six months now in all major modes it supports.

Tree Sitter and lsp-mode might be of help. Looks like both take a bit of work to get going. I have personally not used them, so try out which suits you and let us know how it went.

You can use tree-sitter already if you have dynamic module support: https://github.com/emacs-tree-sitter/elisp-tree-sitter
