Vim syntax and indent plugin for vue files

vim-vue-plugin

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

Installation

[VundleVim][2]
```
  Plugin 'leafOfTree/vim-vue-plugin'
```

[vim-pathogen][5]

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

[vim-plug][7]

  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
```

This 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][4], Coffee with [vim-coffee-script][11].^
A builtin foldexpr foldmethod.^
[emmet-vim][10] HTML/CSS/JavaScript filetype detection.
.wpy files from [WePY][6].

^: 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 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 can be added in ~/.vim/syntax or $VIM/vimfiles/syntax.

Note

filetype is set to vue so autocmds and other custom settings for javascript have to be manually enabled for vue.
g:vim_vue_plugin_load_full_syntax applies to JavaScript/HTML/CSS/SASS/LESS.
g:vim_vue_plugin_use_foldexpr default value used to be 1, but it's changed to 0 now.

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
