There are now 21 projects to my repository. Aside from Lychen and j, these are mostly written in Modula-2, a Wirth-family language. I had a long and deep relationship with Modula-2 during the early 1990s and I miss it still.
You may find something of interest there. It's all under a permissive MIT license.
There are many more to add and in other languages as well, including xBase (Clipper).
