<p>This beautifier can process your messy or compacted javascript, making it all neatly and consistently formatted and
readable.</p>
<p>You can always see the latest version of the code in <a
href="http://github.com/einars/js-beautify">github</a>, and you can download the beautifier for
local use (<a href="http://github.com/einars/js-beautify/zipball/master">zip</a>, <a href="http://github.com/einars/js-beautify/tarball/master">tar.gz</a>) as well.</p>
<h2>Unpacking javascript</h2>
<p>The beautifier has a simple unpacker for <a href="http://dean.edwards.name/packer/">Dean Edward's packer</a>. To unpack javascript, paste (p,a,c,k,e,d) scripts and they'll hopefully get decoded. Your feedback is welcome.</p>
<h2>Formatting from command-line</h2>
<p>To beautify from the command-line you can use provided beautify-cl.js script, using <a href="http://mozilla.com/rhino/">Rhino javascript engine</a>. See the file contents for the details.</p>
<h2><a href="http://fiddler2.com/">Fiddler</a></h2>
<p>This popular web debugging proxy for Windows has a <a href="http://fiddler2.com/Fiddler2/extensions.asp">Javascript Formatter addon</a> (based on this beautifier) which can reformat javascript on the fly.</p>
<h2>Vim</h2>
<p>Aj3423 converted the script to vimscript — and so now there is a <a href="http://www.vim.org/scripts/script.php?script_id=2727">vim plugin</a> for the quality javascript beautifying.</p>
<h2>Other nice things</h2>
<p>If you're writing javascript code, <a href="http://jslint.com/">JSLint</a> is a really fine piece of software, too. You don't have to follow its recommendations blindly, but understanding what it says about your code can greatly improve your skills.</p>
<h2>Contacts</h2>
<p>If you find some problems with the generated javascript, adapt the script for your favorite editor, or something, my email is einars@gmail.com.</p>
