This is a Sublime Text 2 plugin and build system allowing you to check your JavaScript code for nasty errors, coding conventions and other goodies. It relies on JSHint, a fork of JSLint (developed by Douglas Crockford). The linter is itself written in JavaScript, so you'll need something (node.js) to interpret JavaScript code outside the browser.
First of all, be sure you have node.js installed in order to run JSHint (a derivative work of JSLint, used to detect errors and potential problems in JS).
Each OS has a different Packages folder required by Sublime Text. Open it via Preferences -> Browse Packages, and copy this repository contents to a new JSHint folder there.
The shorter way of doing this is:
git clone git://github.com/victorporof/Sublime-JSHint.git ~/Library/Application\ Support/Sublime\ Text\ 2/Packages/JSHint
git clone git://github.com/victorporof/Sublime-JSHint.git %APPDATA%\Sublime Text 2\Packages\JSHint
There are two ways you can use Sublime-JSHint: as a build system or a python plugin.
Open a JavaScript file, Select JSHint from Tools -> Build System, and hit Ctrl+B (or Cmd+B if you're on a Mac).
Open a JavaScript file, pop out the console in Sublime Text from View -> Show Console, and type view.run_command("jshint").
Writing commands in the console is ugly. Set up your own key combo for this, by going to Preferences -> Key Bindings - Default, and adding a command in that huge array: { "keys": ["super+shift+j"], "command": "jshint" },. You can use any other command you want, thought most of them are already taken.
If you get an error sh: node: command not found or similar, you don't have node in the right path. Try setting the absolute path to node in JSHint.py or JSHint.sublime-build!
This means from:
lint = commands.getoutput("node " + ...
change to
lint = commands.getoutput("absolute/path/to/node " + ...
Both JSHint.sublime-build and JSHint.py have some predefined settings which are probably quite important when writing JavaScript code (like "es5: true"). Add some more settings and options from the TONS available (see the JSHint docs).
Have fun!
