I spend my days in vim, currently writing a lot of JavaScript. I've been trying to find a way to integrate JSLint or something similar into vim to improve my coding. Has anyone managed to do something like this?
Edit:
tried this: Javascript Syntax Checking From Vim, unfortunately the output is very crude.
You can follow the intructions from JSLint web-service + VIM integration or do what I did:
Download http://jslint.webvm.net/mylintrun.js and http://www.jslint.com/fulljslint.js and put them in a directory of your choice.
Then add the following line to the beginning of mylintrun.js:
var filename= arguments[0];
and change last line of code in mylintrun.js ("print( ...)") to:
print ( filename + ":" + (obj["line"] + 1) + ":" + (obj["character"] + 1) + ":" + obj["reason"] );
This makes in mylintrun.js output a error list that can be used with the VIM quickfix window (:copen).
Now set the following in VIM:
set makeprg=cat\ %\ \\\|\ /my/path/to/js\ /my/path/to/mylintrun.js\ %
set errorformat=%f:%l:%c:%m
where you have to change /my/path/to/js to the path to SpiderMonkey and /my/path/to/mylintrun.js to the path where you put the JS files.
Now, you can use :make in VIM and use the quickfix window (:he quickfix-window) to jump from error to error.
I wrote a vim script similar to f3lix's solution, but instead of invoking the :make command manually, the script will list any lint warnings in the quickfix window each time you save a javascript file.
i am using JavascriptLint.vim by joestelmach but i am not seeing any errors in my quick fix error window.
Much better is to pipe the results through Lynx to deal with JSLint's unfortunate choice of HTML for output format. I have a blog post on how to do it here:

Another option is jslint.vim from Jesse Hallet. It's available on GitHub and works with or without Vim's QuickFix window. It's a nice plugin!
