How can I use JSBeautify from the command line?

Question

I like jsbeautifier.org and I see they have a github repo with their code. The readme has two examples of how to use this tool via the command line: ``` import jsbeautifier res = jsbeautifier.beautify('your javascript string') res = jsbeautifier.beautify_file('some_file.js') ``` and: ``` opts = jsbeautifier.default_options() opts.indent_size = 2 res = jsbeautifier.beautify('some javascript', opts) ``` How can I incorporate this into a script (`myjsbeautify.py`) so that it can accept either `stdin` or an argument (file name) and output to `stdout` ? I also want to use the option to `keep array indentation`. Desired syntaxes ``` cat ugly.js | myjsbeautify.py ``` or ``` myjsbeautify.py ugly.js ```

Accepted Answer

Check out this post on using JSBeautify with Textmate. It has some good instructions on how to install it on your system. On Mac OS X, I used:

```
cd /tmp
git clone https://github.com/einars/js-beautify.git
cd js-beautify/python
python setup.py install
```

Then you can simply use `js-beautify /path/to/filename.js` to have it run.
