(I dont really know what category to put this on, hopefully this is correct)
I have created a open-source, web based (Snap! itself is web based, of course this had to be), documentation generator for Snap! libraries (or even projects).
It uses special blocks that don't do anything (they just are metadata) that you put at a start of a block to describe the block for the generator.
I don't really know if posting GitHub links is really allowed, but here's the GitHub link for the project. It contains the code and more info. Also, theres the actual generator, hosted using GitHub Pages.
Hope you enjoy! THIS IS A VERY, VERY BETA VERSION OF THIS. ITS UNSTYLED ON BOTH THE GENERATOR PAGE AND THE GENERATED DOCUMENTS, IT DOESNT HAVE ALOT OF THE FEATURES I WANT, ETC ETC. I REALLY WANT TO MAKE SURE YOU KNOW THIS. clears throat
