I've seen a few question regarding stackoverflow users' favorite esoteric (or not) programming languages. There are also questions regarding the implementation of languages. However, I was curious to see if any of you have actually written your own programming language (be it esoteric or not) and I also wanted to know what it looks like.
I enjoy reading about and trying to learn new and inventive languages, so I thought it would be nice to see what the stackoverflow community has to offer. :)
I wrote one for fun a few years ago.
I have written a set of 7 "micro" languages for teaching. Each one is meant to illustrate the key ideas of one of the following full programming languages:
The languages deliberately look very much one like the other, so that students see only essential differences, never gratuitous ones. I want to do two more, based on Haskell and CLU.
Sam Kamin had the original idea and helped a lot with the design.
