NoExcess
NoExcess is a scheme-like programming language that is written in C. The goal of this project is to create a stripped down version of scheme that with a minimal set of built-in functions that work with the built-in datatypes. Users can make their own versions of NoExcess by writing macros that alter the way the language is written. I wrote the bulk of this thing in a caffeine binge of three days. It's a pretty cool program!
The language is currently not ready for release, although you can play around with it and most things will work.
You can get the program here:
git clone git://prestonpan.tech/no_excess.git
If you still have problems getting the copies of the software, you can browse my git frontend for the software names.
