Vim syntax highlighting for Vue components.

This was initially forked from darthmall/vim-vue. I already have an implementation for this but found his code much cleaner. That's why I created a new version instead of a PR.

Plugin 'posva/vim-vue'

cd ~/.vim/bundle && \
git clone https://github.com/posva/vim-vue.git

git clone https://github.com/posva/vim-vue.git ~/.vim/pack/plugins/start/vim-vue

Currently only eslint is available. Please make sure eslint and eslint-plugin-vue are installed and properly configured:

npm i -g eslint eslint-plugin-vue

If your language is not getting highlighted open an issue or a PR with the fix. You only need to add a line to the syntax/vue.vim file.

Don't forget to write Vader tests for the code you write. You can run the tests by executing make test in the terminal.

Jade has been renamed to pug. Therefore you have to replace all your jade occurrences with pug. The new plugin for pug can be found on the same repository (the name has already been updated).

This is because Vim tries to highlight text in an efficient way. Especially in files that include multiple languages, it can get confused. To work around this, you can run :syntax sync fromstart when it happens.

You can also setup an autocmd for this, so that every time a Vue file is opened, :syntax sync fromstart will be executed pre-emptively:

autocmd FileType vue syntax sync fromstart

See :h :syn-sync-first and this article for more details.

If you already have some configuration for filetypes like html, css and javascript (e.g. linters, completion), an easy way to use them in Vue files is by setting compound filetypes like this:

autocmd BufRead,BufNewFile *.vue setlocal filetype=vue.html.javascript.css

⚠️ This may cause problems, because some plugins will then treat the whole buffer as html/javascript/css instead of only the part inside the tags. Ideally, you should configure everything that you want to use in Vue files individually.

caw.vim features built-in support for file context through context_filetype.vim. Just install both plugins and context-aware commenting will work in most files. The fenced code is detected by predefined regular expressions.

let g:ft = ''
function! NERDCommenter_before()
  if &ft == 'vue'
    let g:ft = 'vue'
    let stack = synstack(line('.'), col('.'))
    if len(stack) > 0
      let syn = synIDattr((stack)[0], 'name')
      if len(syn) > 0
        exe 'setf ' . substitute(tolower(syn), '^vue_', '', '')
      endif
    endif
  endif
endfunction
function! NERDCommenter_after()
  if g:ft == 'vue'
    setf vue
    let g:ft = ''
  endif
endfunction

Add let g:vue_disable_pre_processors=1 in your .vimrc to disable checking for prepocessors. When checking for preprocessor languages, multiple syntax highlighting checks are done, which can slow down vim. This variable prevents vim-vue from supporting every pre-processor language highlighting.
