I've been trying to collect Literate Programs collected as books at:

Note that ICC, a C compiler, is one:

Note that one can look through projects tagged as Literate Programming by using the topics view:
https://github.com/topics/literate-programming
might be there's something useful there.

There is! As of now, if you sort by recently updated, my literate programming project is the first result :P (link in profile if anyone reads this later)
In the interest of full disclosure, my own project is in there as well (but nowhere near the top and it's a kind of obscure topic, so not likely to ever get there).
