This is kind of a dumb question, but do you know of any good solutions that allow the use of Angular with CoffeeScript, Bootstrap, AND a higher-level templating language like HAML?
(I know I'm pretty much combining "hip" programming buzzwords here, but I am curious.)
Angular + Bootstrap = use Angular UI Bootstrap. For
Coffee use on-the-fly transcompilation of your choice (i.e. grunt-contrib-coffee + grunt-contrib-watch). For any of
higher-level templating again use on-the-fly compilation (i.e. grunt-haml + grunt-contrib-watch)
Based on yeoman (http://yeoman.io), which I used briefly for the first time a few days ago, and it seems like a nice system. It already has pretty good integration with the AngularJS seed project.
You could probably roll something together using middleman (http://middlemanapp.com) too, with a bit more legwork.
