(If you want to see the old 50-language version, see 50 branch.)

Usage

Ubuntu

If you are using Ubuntu 20.04 LTS (Focal Fossa), you can perform the following steps.

1. Install all interpreters/compilers.

First, you have to type the following apt-get command to install all of them.

$ sudo apt-get install afnix algol68g aplus-fsf aspectc++ aspectj \
  asymptote ats2-lang bash bc bf bsdgames bsh clisp clojure cmake \
  coffeescript dafny dc ecere-dev elixir emacs-nox erlang f2c fish flex \
  fp-compiler fsharp g++ gambas3-script gap gawk gcc gdb gdc \
  generator-scripting-language genius gforth gfortran ghc ghostscript \
  gnat gnu-smalltalk gnucobol gnuplot gobjc golang groovy guile-2.0 gzip \
  haxe icont iconx intercal iverilog jasmin-sable jq julia ksh lisaac \
  livescript llvm lua5.3 m4 make maxima minizinc mlton mono-devel \
  mono-mcs mono-vbnc nasm neko nickle nim node-typescript nodejs ocaml \
  octave openjdk-11-jdk pakcs pari-gp parser3-cgi perl php-cli pike8.0 \
  python3 r-base rakudo ratfor rc regina-rexx ruby ruby-mustache rustc \
  scala scilab-cli sed slsh spin squirrel3 swi-prolog tcl tcsh valac vim \
  xsltproc yabasic yorick zoem zsh

Then, build the bundled interpreters.

$ sudo apt-get install cmake libpng-dev libgd-dev groff bison curl
$ make -C vendor

2. Run each program on each interpreter/compiler.

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.

Frequently asked questions

Q. Why?

A. Take your pick.

Q. How?

A. Good news: I published a book, "The world of obfuscated, esoteric, artistic programming". It explains how to write a quine, an ascii-art quine, and a uroboros quine like this quine-relay. You can buy my book on amazon.co.jp.

(It also contains my almost all (about forty) works, including alphabet-only Ruby program, radiation-hardened quine, etc., and explains many techniques to write such programs.)

Bad news: It is written in Japanese. I hope you could translate it to English and help me earn royalties.

Q. Language XXX is missing!

A. See the criteria for language inclusion in detail. (In short: please create a deb package and contribute it to Ubuntu.)
