jformatter
A JavaScript formatter
Basic usage
The easiest way to use JFormatter is to install it as a Node program.
npm -g install jformatter
After you've done that you should be able to use the jformatter
program.
jformatter file.js
Command in Terminal
Usage: jformatter [options] <file>
Options:
-h, --help output usage information
-v, --version output the version number
-d, --diff Show difference between source and formatted
Configuration
When use jformatter in terminal, it will try to load .jformatterrc

JFormatter will start looking for this file in the same directory as the file that's being formatted. If not found, it will move one level up the directory tree all the way up to the filesystem root.
Default config, developing, not stable.
