A few days ago I started work on a simple Scheme-like Lisp interpreter written in Javascript. I’m calling it simplescheme.js.
It started out as a way to study for my programming languages class and to gain a better understanding of the Scheme programming language, and I found myself having a lot of fun doing it so I kept going. Right now it’s far from complete, but it’s certainly usable in its current form.
I set up a web interface here that lets you enter and run code inside a browser.
After I started working on the interpreter I read that John McCarthy, the creator of Lisp, recently died. First Dennis Ritchie, now this — October has been a bad month for us computer geeks.
