I'm currently using emacs 30 and this version has support for more languages using the new ts-modes
, I've been using emacs-tree-sitter package since Emacs added dynamic modules feature.
Now using emacs 30
I give a try to use only ts-modes
and maybe delete some external packages I was using.
How to install grammars
Emacs doesn't have a built-in way to install automatically most common grammar so we're going to use a package that can handle that, we use tree-sitter-langs package, which is a repository for grammars.
When we install it it download and install all the available grammars in its own directory but to be used by emacs ts-modes
we need to put them inside /.emacs.d/tree-sitter
directory. I write a helper function to accomplish this:
(defun my/copy-grammars-to-emacs-tree-sitter-dir ()
"Copy tree-sitter grammar files to native Emacs dir."
(interactive)
(let* ((files (directory-files (tree-sitter-langs--bin-dir) nil "\\.dylib$")))
(dolist (grammar-file files)
(copy-file (concat (tree-sitter-langs--bin-dir) grammar-file) (concat (expand-file-name user-emacs-directory) "tree-sitter/" "libtree-sitter-" grammar-file) t)
(message "%s grammar files copied" (length files)))))
The migration
I use straight.el
to manage my packages so I'm going to use it to configure built-in ts-modes
, by now I only migrated a few modes.
For elixir
:
(use-package elixir-ts-mode
:straight (:type built-in)
:mode (("\\.ex\\'" . elixir-ts-mode)
("\\.exs\\'" . elixir-ts-mode)
("\\mix.lock\\'" . elixir-ts-mode)))
For docker
:
(use-package dockerfile-ts-mode
:straight (:type built-in)
:defer t
:mode (("\\Dockerfile\\'" . dockerfile-ts-mode)
("\\.dockerignore\\'" . dockerfile-ts-mode)))
For typescript
(use-package typescript-ts-mode
:straight (:type built-in)
:defer t
:mode "\\.tsx?\\'")
For toml
(use-package toml-ts-mode
:straight (:type built-in)
:mode "\\.toml\\'"
:defer t)
For yaml
(use-package yaml-ts-mode
:straight (:type built-in)
:mode "\\.ya?ml\\'")
With this now I have 5 dependencies less in my configuration :).
Conclusion
I'm in the process to migrate others modes like python-mode
, go-mode
and so on but in some cases syntax highlighting is not the best. For example shell-script-mode
has better highlight than bash-ts-mode
. I'm been using these "new" ts-modes
for a few weeks and everything is working well.
Bonus
I also updated a package I use to run ispell
on text nodes to support built-in tree-sitter support. Now it supports tree-sitter.el
and treesit
packages.
