Quine Chameleon

A polymorphic program that transforms itself into different languages.

Why

I'd like to learn new programming languages and I'm bored with Hello World's.

How to Play

Dancing Chameleon

make dance - Press ctrl-c to stop

Crawling Chameleon

make crawl - Each step it outputs itself in a random language

Dependencies

Python3 is required. You will also need other compilers/interpreters to run various output.

Here's a quick install-all command for Ubuntu 15.04:

sudo apt-get install clojure1.6 coffeescript emacs24-nox fsharp g++ gawk gcc gdc ghc gobjc golang-go haxe libghc-random-dev libghc-regex-compat-dev lua5.2 mono-mcs nodejs ocaml octave openjdk-7-jdk perl6 python3 r-base racket ruby scala valac

Note: Scala 2.9.2 does not work with Java 8

Variants

  • make ouroboros: languages are went through in alphabetical order
  • make random-ouroboros: languages are went through in a random order
  • make multiquines: Multiquines. The target language is specified through command-line. E.g. python3 multiquines.py cpp (See rules below)

My Testing Environment

Ubuntu 15.04 with the following compilers/interpreters

  • CoffeeScript 1.4.0
  • fsharp 3.1.1.26
  • GCC 4.9.2
  • GHC 7.6.3
  • GNU Awk 4.1.1
  • GNU Emacs 24.4.1
  • GNU Octave 3.8.2
  • Go 1.3.3
  • Haxe 3.0.0
  • Lua 5.2.3
  • Mono 3.2.8
  • Node.js 0.10.25
  • OCaml 4.01.0
  • OpenJDK 7
  • Python 3.4.3
  • R 3.1.2
  • Racket 6.1
  • Rakudo 2014.07
  • Ruby 2.1.2
  • Scala 2.9.2
  • Vala 0.26.2

Rules (beta)

  • Source
    • No undefined behaviors
    • No compiler/interpreter warnings
    • As short as possible
    • The main class/module name must be QC, if required
  • Behavior
    • Random sequence should not remain the same
      • Set random seed when necessary
    • Use only standard libraries
    • No file operations
      • #!/bin/cat - Bash
    • No source inspections
      • .toSource() - JavaScript
    • No definition as compiler flags
      • -D for gcc, g++, valac
    • stdin is not closed
      • Use BEGIN instead of END in AWK
  • Language
    • Use languages available to Ubuntu 15.04
      • Or easily obtainable
    • Use latest standard if not compatible
      • Python3 vs Python2
      • Perl6 vs Perl5
  • Multiquines
    • A valid language suffix must be specified as the only command-line argument
      • Otherwise the behavior is undefined

Naming Convention

For readability, here are some common variables names used, with exceptions:

  • A: command line arguments
  • I: index of specified language (in the language array)
  • L: data array by splitting S
  • S: compact data string
