A major mode for editing Vue components. Requires Emacs 29.1.

Clone this repo anywhere you want, probably somewhere in ~/.emacs.d . Then, add the directory to your load-path.

For example:

cd ~/.emacs.d
git clone https://github.com/8uff3r/vue-ts-mode.git

Then, in init.el:

(add-to-list 'load-path (concat user-emacs-directory "vue-ts-mode"))
(require 'vue-ts-mode)

The first time you open a .vue file, or (require 'vue-ts-mode), you’ll likely get a warning such as the following:

Cannot activate tree-sitter, because language grammar for vue is unavailable

Because this major mode is powered by Tree-sitter, it depends on an external grammar to provide a syntax tree for Vue components. To set it up, you’ll need to set treesit-language-source-alist to point to the correct repositories for each language. At a minimum, you’ll need to specify vue, typescript and css, like so:

(setq treesit-language-source-alist
      '((vue "https://github.com/ikatyang/tree-sitter-vue")
        (css "https://github.com/tree-sitter/tree-sitter-css")
        (typescript "https://github.com/tree-sitter/tree-sitter-typescript" "master" "tsx/src")))

Once that’s been setup, you’ll need to run treesit-install-language-grammar once for each language in the list. You can do this interactively (M-x), or by evaluating this snippet:

(mapc #'treesit-install-language-grammar '(vue css typescript))

Make sure you have a working C compiler as cc in your PATH, since this needs to compile the grammars.

• Ruby Iris Juric for astro-ts-mode, which this is based on, even this Readme :)
