Ever been away from your computer and thought, "Boy, I wish I couldbe writing Scheme code right now"? Well, now you can! Simple Schemeis a Java/Android implementation of a Scheme-like programminglanguage and syntax highlighted editor. It includes implementationsof most features found in traditional Scheme (e.g., definitions,let, let*, letrec, if, cond, lambda, lists) with a very similarsyntax. Because it's implemented in Java, we use long and doubletypes to represent numbers, e.g., 2/3 does not have an exactrepresentation. Simple Scheme also includes an implementation ofimage functions similar to Racket's image module(http://docs.racket-lang.org/teachpack/2htdpimage.html). Seehttp://bryanchadwick.com/simplescheme/ for documentation andexamples. Enjoy!
