"Befunge is a two-dimensional fungeoidal (in fact, the original fungeoid) esoteric programming language invented in 1993 by Chris Pressey with the goal of being as difficult to compile as possible." - Esolangs
This code is a Ruby implementation of Befunge's interpreter. It means that you can run befunge code inside your ruby application and get it's output during runtime.
require 'BefungeInterpreter'
befungeCode = "64+\"!dlroW ,olleH\">:\#,_@"
interpreter = BefungeInterpreter.new(befungeCode)
interpreter.execute
interpreter.output #=> "Hello, World!\n"BefungeInterpreter is licensed through BSD-3-Clause
