Derpa is an interpreter for the Brainfuck language ( http://en.wikipedia.org/wiki/Brainfuck ) written in Clojure. I'm writing Derpa as an exercise for learning Clojure.

Currently, Derpa is a command-line interpreter, but I am planning to port the code to ClojureScript and hook it up to a simple, interactive web-app, allowing you to enter Brainfuck code on a web page and see it executed. This will be a great opportunity for me to practice ClojureScript and learn about Reagent.

cd derpa

lein run "++++++++++[>++++++++++<-]>.+.+++++++++++++.--.---------------."

(This particular Brainfuck code prints "derpa")

There are probably a few bugs to do with unmatched loop braces and <'ing or >'ing out of the cells. Also, not a bug, but just something weird about the code - the indentation is screwed because of a bug in Vim where the = indentation mechanism just gives in after a big bunch of nested or neighbouring forms. I will be filing a bug report for this Vim problem.

• Port to ClojureScript
• Figure out if main function 'interpret' could be made more idiomatic... and possibly smaller.
• Create web-app that lets you enter Brainfuck code and see it executed visually
• (Possibly) make cells endless with some sort of lazy sequence generation
• (Possibly) write unit-tests :3
• Figure out licensing? I'm new to publicizing stuff :/
