html foo.html will write the prettified version to stdout.

html *.html will update in place all matching html files with their prettified versions.

Advanced usage

I find myself constantly using the 'Copy as HTML' feature of the Chrome Inspector:

The downside is that that usually the HTML that gets copied is pretty ugly:

On OS X you can use pbpaste and pbcopy to stream your clipboard in and out of unix pipes. With the ugly HTML still in your clipboard run this command:

pbpaste | html | pbcopy

Now when you paste your clipboard into an editor you will get nice, pretty printed HTML:

Upgrading

grab the newest beautify-html.js from js-beautifier and drop it into lib/ as html.js. then add the following code to the bottom of html.js:

  module.exports = { prettyPrint: style_html }
