ThinLisp

Some notes on ThinLisp, a dialect of Lisp for real-time systems. Thin Lisp was written by Gensym Corporation in the ’90s. The general idea is that you develop your program using a subset of Common Lisp, and then compile it into efficient C. Garbage collection is avoided by using object pools, arenas, and similar tricks familiar to advanced C programmers.

The current home of ThinLisp seems to be Vladimir Sedach’s Code Page . Vladimir seems to have used it for “one small OpenGL” project before abandoning it. He seems to be happily hacking ParenScript (a Lisp to Javascript translator) these days.

The Scheme guys have similar, but more modest, sysems: Schelp, and PreScheme (part of Scheme48).
