tsi.el VS combobulate

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.

Eh, I've been looking and haven't found anything for other editors that actually tries to use TreeSitter for anything beyond highlighting. The Emacs structural editing packages are still very WIP but at least they exist.

(And also some have been based on the out of tree implementation that's been around for a while now)

Example: https://github.com/mickeynp/combobulate

Looking at https://github.com/mickeynp/combobulate/blob/master/combobulate-python.el, it at the very least delegates to python-indent-calculate-levels, so the logic is mixed.

I went from an old config rich setups from before lsp's to lsp-mode ones etc... Right now I would say that eglot + pylsp gives you the best experience, you can use pyenv and pyvenv mode to manage your virtual environments. Now that treesitter is also being used you can try out https://github.com/mickeynp/combobulate

I think the following packages would fit your wishlist, as it is very similar to mine. As mentioned in the replies, there is (https://github.com/magnars/expand-region.el) and (https://github.com/mickeynp/combobulate). I regularly use (https://github.com/Fuco1/smartparens).

re syntactic text objects: https://github.com/mickeynp/combobulate

I haven't used it, but based on the description, it looks like combobulate would be an example of this:

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)

blockman usage examples: https://www.youtube.com/channel/UC5539gDeAdWqeXcczWuhnBA

Alternative examples / takes (per user interface):

### embedding a block of source code in a document:

  ** carrotsearch.gethub.io/apidocs/code-blocks

I don't know what this fork brings to table, but you could try tree-sitter today with your vanilla Emacs using a package[1] that works via dynamic module.

Personally I am more interested in getting structural selection and navigation reliably working for any language. There is also a package named combobulate[2] to help with that.
