There is a "pretty" option in Jade itself:

var jade = require("jade");

var jade_string = [
    "!!! 5",
    "html",
    "    body",
    "        #foo  I am a foo div!"
].join("\n");

var fn = jade.compile(jade_string, { pretty: true });
console.log( fn() );

...gets you this:

<!DOCTYPE html>
<html>
  <body>
    <div id="foo">I am a foo div!
    </div>
  </body>
</html>

I doesn't seem to be very sophisticated but for what I'm after -- the ability to actually debug the HTML my views produce -- it's just fine.

In express 4.x, add this to your app.js:
```
app.locals.pretty = app.get('env') === 'development';
```

Do you really need nicely formatted html? Even if you try to output something that looks nice in one editor, it can look weird in another. Granted, I don't know what you need the html for, but I'd try using the chrome development tools or firebug for Firefox. Those tools give you a good view of the DOM instead of the html.

If you really-really need nicely formatted html then try using EJS instead of jade. That would mean you'd have to format the html yourself though.
