Lightweight, customizable and functional Vim plugin for JSHint integration.

• Linting whole file or selected lines without saving to disk.
• Using project-specific (locally installed) version of JSHint and JSHint configuration files if available.
• Setting lint flags from command line with autocompletion.
• Optionally opening list of linting errors with useful shortcuts.
• Optionally validating files after reading or saving.
• Working on Linux, Windows (with JSHint 2.1.5 and newer) and OS X.

1. Install Node.js and JSHint.
2. Clone plugin into your ~/.vim/bundle/jshint2.vim/.
3. Install Pathogen or just add set runtimepath+=~/.vim/bundle/jshint2.vim/ into your .vimrc.
4. Optionally place .jshintrc into your home and/or project directory.
5. ???
6. PROFIT!

Use :JSHint command inside Vim to lint whole file or :'<,'>JSHint to lint only selected lines. Add ! to suppress opening error list (number of lint errors still will be shown), add space and use tab key to complete space separated lint flags — :JSHint! white:true eqeqeq:true. Use - to ignore errors by their codes — :JSHint -E001 -W002 -I003.

t — open error in new tab. T — open error in new tab with error list. v — open error in new vertical split. V — open error in new vertical split with error list. s — open error in new horizontal split. S — open error in new horizontal split with error list. i — ignore selected error. n — scroll to selected error. q — close error list.

Set global JSHint command path (mostly for Windows):

let jshint2_command = '~/path/to/node_modules/.bin/jshint'

Lint JavaScript files after reading it:

let jshint2_read = 1

Lint JavaScript files after saving it:

let jshint2_save = 1

Do not automatically close orphaned error lists:

let jshint2_close = 0

Skip lint confirmation for non JavaScript files:

let jshint2_confirm = 0

Do not use colored messages:

let jshint2_color = 0

Hide error codes in error list (if you don't use error ignoring or error codes confuses you):

let jshint2_error = 0

Set min and max height of error list:

let jshint2_min_height = 3
let jshint2_max_height = 12

Quick lint mapping:

" jshint validation
nnoremap <silent><F1> :JSHint<CR>
inoremap <silent><F1> <C-O>:JSHint<CR>
vnoremap <silent><F1> :JSHint<CR>

" show next jshint error
nnoremap <silent><F2> :lnext<CR>
inoremap <silent><F2> <C-O>:lnext<CR>
vnoremap <silent><F2> :lnext<CR>

" show previous jshint error
nnoremap <silent><F3> :lprevious<CR>
inoremap <silent><F3> <C-O>:lprevious<CR>
vnoremap <silent><F3> :lprevious<CR>
