Scheme

A compilation of colleges, universities, and secondary schools which use Scheme in their curricula. Compiled and maintained by Ed Martin of Schemers, Inc.

Scheme-like language developed at Yale; is to Scheme rather as NIL is to Lisp; mainly of interest to historians and theoreticians. FTP for v3.1.

Based on Mini-Scheme, tiny implementation, almost a full R5RS Scheme. Goal: embedded scripting use, but works as standalone interpreter and extensible shell tool. Recent changes reduced executable size to about 64KB on Linux/x86. [BSD]

Based on XLisp, but with built-in statistics support.

For DrScheme, semi-structured program editing; an alternative set of key bindings. When it is on, the most important functions can run via unchorded keystrokes, and motion commands work on sexps by default.

Guile bindings for Gtk+.
