An uroboros program with 50 programming languages

Quine Relay

What this is

This is a Ruby program that generates Scala program that generates Scheme program that generates ...(through 50 languages)... REXX program that generates the original Ruby code again.

Usage

1. Install all interpreters/compilers.

You are fortunate if you are using Ubuntu 13.04 (Raring Ringtail). You just have to type the following apt-get command to install all of them.

$ sudo apt-get install algol68g bash beef boo clisp clojure1.4 \
  coffeescript f2c fp-compiler g++ gauche gawk gcc gforth gfortran ghc \
  gnat gnu-smalltalk gobjc golang groovy icont intercal iverilog \
  jasmin-sable llvm lua5.2 make mono-devel mono-mcs nodejs ocaml octave \
  open-cobol openjdk-6-jdk parrot perl php5-cli pike7.8 python r-base \
  regina-rexx ruby1.9.3 scala swi-prolog tcc tcl8.5 ucblogo valac

You may find instructions for Arch Linux and other platforms in the wiki.

If you are not using these Linux distributions, please find your way yourself. If you could do it, please let me know. Good luck.

2. Run each program on each interpreter/compiler.

$ ruby QR.rb > QR.scala
$ scalac QR.scala && scala QR > QR.scm
$ $(SCHEME) QR.scm > QR.bash
$ bash QR.bash > QR.st
$ gst QR.st > QR.tcl
$ tclsh QR.tcl > QR.unl
$ ruby unlambda.rb QR.unl > QR.vala
$ valac QR.vala && ./QR > QR.v
$ iverilog -o QR QR.v && ./QR -vcd-none > QR.ws
$ ruby whitespace.rb QR.ws > qr.adb
$ gnatmake qr.adb && ./qr > QR.a68
$ a68g QR.a68 > QR.awk
$ awk -f QR.awk > QR.boo
$ booi QR.boo > QR.bf
$ beef QR.bf > QR.c
$ gcc -o QR QR.c && ./QR > QR.cpp
$ g++ -o QR QR.cpp && ./QR > QR.cs
$ mcs QR.cs && mono QR.exe > QR.clj
$ clojure QR.clj > QR.cob
$ cobc -x QR.cob && ./QR > QR.coffee
$ coffee QR.coffee > QR.lisp
$ clisp QR.lisp > QR.fs
$ gforth QR.fs > QR.f
$ f2c QR.f && tcc -o QR QR.c -L/usr/lib -lf2c && ./QR > QR.f90
$ gfortran -o QR QR.f90 && ./QR > QR.go
$ go run QR.go > QR.groovy
$ groovy QR.groovy > QR.hs
$ runghc QR.hs > QR.icn
$ icont -s QR.icn && ./QR > QR.i
$ CC=tcc ick -b QR.i && ./QR > QR.j
$ jasmin QR.j && java QR > QR.java
$ javac QR.java && java QR > QR.ll
$ llvm-as QR.ll && lli QR.bc > QR.logo
$ logo QR.logo > QR.lua
$ lua QR.lua > QR.makefile
$ make -f QR.makefile > QR.il
$ ilasm QR.il && mono QR.exe > QR.js
$ $(NODE) QR.js > QR.m
$ gcc -o QR QR.m && ./QR > QR.ml
$ ocaml QR.ml > QR.octave
$ octave -qf QR.octave > QR.pasm
$ parrot QR.pasm > QR.pas
$ fpc QR.pas && ./QR > QR.pl
$ perl QR.pl > QR.php
$ php QR.php > QR.pike
$ pike QR.pike > QR.prolog
$ swipl -q -t qr -f QR.prolog > QR.py
$ python QR.py > QR.R
$ R --slave < QR.R > QR.rexx
$ rexx ./QR.rexx > QR2.rb

You will see that QR.rb is the same as QR2.rb.

$ diff QR.rb QR2.rb

Alternatively, just type make.

$ make

Note: It may require huge memory to compile some files.

Tested interpreter/compiler versions

As I said above, I tested the program on Ubuntu. It does not provide Unlambda and Whitespace interpreters, so this repository includes my own implementations. For other languages, I used the following deb packages:

How to re-generate the source

$ cd src
$ rake
