vim-vue-plugin

Vim syntax and indent plugin for .vue files. Mainly inspired by mxw/vim-jsx.

Install

• VundleVim

    Plugin 'leafOfTree/vim-vue-plugin'
  

• vim-pathogen

    cd ~/.vim/bundle && \
    git clone https://github.com/leafOfTree/vim-vue-plugin --depth 1
  

• vim-plug

    Plug 'leafOfTree/vim-vue-plugin'
    :PlugInstall
  

• Or manually, clone this plugin to path/to/this_plugin, and add it to rtp in vimrc

    set rtp+=path/to/this_plugin
  

The plugin works if filetype is set to vue. Please stay up to date. Feel free to open an issue or a pull request.

How it works

Since .vue is a combination of CSS, HTML and JavaScript, so is vim-vue-plugin. (Like XML and JavaScript for .jsx).

Supports

• Vue directives.
• Less/Sass/Scss, Pug with vim-pug, Coffee with vim-coffee-script.^
• A builtin foldexpr foldmethod.^
• emmet-vim HTML/CSS/JavaScript filetype detection.
• .wpy files from WePY.

^: see Configuration for details.

Configuration

Set global variable to 1 to enable or 0 to disable. Ex:

let g:vim_vue_plugin_load_full_syntax = 1

variable	description	default
g:vim_vue_plugin_load_full_syntax*	Enable: load all syntax files in runtimepath to enable related syntax plugins. Disable: only in $VIMRUNTIME/syntax, ~/.vim/syntax and $VIM/vimfiles/syntax	0
g:vim_vue_plugin_use_pug*	Enable vim-pug pug syntax for <template lang="pug">.	0
g:vim_vue_plugin_use_coffee	Enable coffee syntax for <script lang="coffee">.	0
g:vim_vue_plugin_use_less	Enable less syntax for <style lang="less">.	0
g:vim_vue_plugin_use_sass	Enable scss syntax for <style lang="scss">(or sass fo lang="sass").	0
g:vim_vue_plugin_has_init_indent	Initially indent one tab inside style/script tags.	0 for .vue. 1 for .wpy
g:vim_vue_plugin_highlight_vue_attr	Highlight vue attribute value as expression instead of string.	0
g:vim_vue_plugin_use_foldexpr	Enable builtin foldexpr foldmethod.	0
g:vim_vue_plugin_debug	Echo debug messages in messages list. Useful to debug if unexpected indents occur.	0

*: Vim may be slow if the feature is enabled. Find a balance between syntax highlight and speed. By the way, custom syntax could be added in ~/.vim/syntax or $VIM/vimfiles/syntax.

Note

• filetype used to be set to javascript.vue, which caused javascript syntax to be loaded multiple times and a significant delay. Now it is vue so autocmds and other settings for javascript have to be manually enabled for vue.
• g:vim_vue_plugin_use_foldexpr default value used to be 1. But there are other foldmethod choices, so it's changed to 0.

Context based behavior

As there are more than one language in .vue file, the different behaviors like mapping or completion may be expected under different tags.

This plugin provides a function to get the tag where the cursor is in.

• GetVueTag() => String Return value is 'template', 'script' or 'style'.

Example

autocmd FileType vue inoremap <buffer><expr> : InsertColon()

function! InsertColon()
  let tag = GetVueTag()
  
  if tag == 'template'
    return ':'
  else
    return ': '
  endif
endfunction

emmet-vim

Currently emmet-vim works regarding your HTML/CSS/JavaScript emmet settings, but it depends on how emmet-vim gets filetype and may change in the future. Feel free to report an issue if any problem appears.

Avoid overload

Since there are many sub languages included, most delays come from syntax files overload. A variable named b:current_loading_main_syntax is set to vue which can be used as loading condition if you'd like to manually find and modify the syntax files causing overload.

For example, the builtin syntax sass.vim and less.vim in vim8.1 runtime and pug.vim in vim-pug/syntax will always load css.vim which this plugin already loads. It can be optimized like

- runtime! syntax/css.vim
+ if !exists("b:current_loading_main_syntax")
+   runtime! syntax/css.vim
+ endif
