Google releases its own Javascript Lint tool

Here's a couple of lines to let you use this with :make (on a single file) and the QuickFix window in Vim:<p><pre><code> au BufNewFile,BufRead *.js set makeprg=gjslint\ % au BufNewFile,BufRead *.js set errorformat=%-P-----\ FILE\ \ :\ \ %f\ -----,Line\ %l\\,\ E:%n:\ %m,%-Q,%-GFound\ %s,%-GSome\ %s,%-Gfixjsstyle%s,%-Gscript\ can\ %s,%-G </code></pre> If any experts in Vim's makeprg/errorformat want to clean this up, that would be awesome. I just hacked it together and it seems to work well enough.

The installation instructions tell you to run "easy_install <a href="http://closure-linter.googlecode.com/files/closure_linter-latest.tar.gz" rel="nofollow">http://closure-linter.googlecode.com/files/closure_linter-la...</a>. All well and good, but install instructions that don't reference specific version numbers freak me out. I might have gotten a little too much reproducibility religion, with all that that entails, but it seems better than being so cavalier when setting up environments.

Does anyone know how this would differ from jslint? I couldn't find anything immediately obvious.

I was hoping I could run this realtime in vim, but it appears too slow on a 1000 line JS file.

Ouch, they shipped with a broken fixjsstyle command: <a href="http://groups.google.com/group/closure-linter-discuss/browse_thread/thread/30fa86792d11b208" rel="nofollow">http://groups.google.com/group/closure-linter-discuss/browse...</a> Luckily it didn't break my jsfile, but that's kind of clumsy.

It fails on file I have thrown at it with some complexity other than jquery.
