Pretty-printing Wordpress HTML output for development purposes

Question

Is there a simple way (plugin / function) that uses Tidy or some other lib to pretty-print Wordpress's HTML output?

It's unreadable as it is and it's almost impossible to write a theme with proper indentation with all the includes / hooks going on all over the place.

Performance is not an issue as this only needs to be active for development purposes.

Answer 1

I suggest:

1. Get Firebug
2. Use PHP heredocs
3. Include whitespace in your output using \n (newline), \t (tab), etc.

Answer 2

WP-Beautifier sounds like it might do what you want.
