In the last decade, I have specified and implemented an unusual programming language that fits my personal taste.
I am constantly revising the language, so some details will change.
There is a Tutorial (also as PDF) and a Language Description (also as PDF), plus a simple TAV-PL playground to test small programs online (including more elaborate examples not in the tutorial).
TAV-PL is a precompiler for the C programming language; the current version is developed and tested in Debian Linux. Supporting Windows was checked years ago and was working; real support requires someone with corresponding experience.
The differences and highlights are:
The source code for the compiler, runtime system and library are available as open source: http://tavpl.de. There you will find also a minimal deb package (without dependencies) and an AppImage to compile and run programs without installation.
If you have comments or questions, write to info@tavpl.de or try a chat with tavpl via JAMI or with tav@glaschick.de via XMPP.
