Hanna is an RDoc template that scales. It's implemented in Haml, making it clean and readable. It's built with simplicity, beauty and ease of browsing in mind.
Hanna is far from done, but it is the first RDoc template that's actually maintainable. First thing I have done is converted the original HTML template to Haml and Sass, cleaning up and removing the (ridiculous amount of) duplication.
Also, the template fragments are now in separate files. You would have fainted if you seen how it was before. (It's really no wonder why there are no other RDoc templates around ... save one: Allison.)
Ultimately, I'd like to lose the frameset. Currently that is far from possible because the whole RDoc HTML Generator is built for frames. Still, that is my goal.
Don't like something? Think you can design better? (You probably can.)
This is git. I welcome all submissions towards my goal.
