Quine Relay
What this is
QR.rb is a Ruby program that generates a Rust program that generates a Scala program that generates ...(through 128 languages in total)... a REXX program that generates the original Ruby code again.
(If you want to see the old 50-language version, see the 50 branch.)
Usage
Ubuntu
If you are using Ubuntu 24.10 (Oracular Oriole), you can follow these steps.
1. Install all the interpreters/compilers.
First, you need to type the following apt-get command to install them all.
$ sudo apt-get install afnix algol68g aplus-fsf aspectj asymptote \
ats2-lang bash bc bsh clisp clojure cmake coffeescript crystal dc \
dhall dotnet8 elixir emacs-nox erlang execline f2c fish flex \
fp-compiler g++ gambas3-gb-pcre gambas3-scripter gap gawk gcc gdb gdc \

gobjc golang gpt groovy guile-3.0 gzip haxe icont iconx intercal \
iverilog jasmin-sable jq kotlin ksh libevent-dev libpolyml-dev lisaac \

rc regina-rexx ruby ruby-mustache rustc scala scilab-cli sed slsh spin \
squirrel3 surgescript swi-prolog tcl tcsh valac vim wabt xsltproc \
yabasic yorick zoem zshThen, build the bundled interpreters.
$ sudo apt-get install cmake libpng-dev libgd-dev groff bison curl
$ make -C vendor2. Run each program on each interpreter/compiler.

$ diff QR.rb QR2.rbAlternatively, just type make.
$ makeNote: It may take a lot of memory to compile some files.
Docker
Simply build the image and run a container as follows:
$ docker build -t qr .
$ docker run --privileged --rm -e CI=true qrNote: You must run in privileged mode, otherwise the maxima command will fail.
If you want to check the generated files, you can mount the local directory in the Docker container (but still use the vendor directory of the container), as follows:
$ docker run --privileged --rm -e CI=true -v $(pwd):/usr/local/share/quine-relay -v /usr/local/share/quine-relay/vendor qrOther platforms
You may find instructions for other platforms in the wiki.
If you do not use these Linux distributions, please find your own way. If you manage it, please let me know. I wish you good luck.

Frequently asked questions
Q. Why?
A. Take your pick.
Q. How?
A. Good news: I have published a book, "The World of Obfuscated, Esoteric, Artistic Programming". It explains how to write a quine, an ascii-art quine, and an uroboros quine like this quine-relay. You can buy my book on amazon.co.jp.
(It also contains my almost all of my (about forty) works, including alphabet-only Ruby program, radiation-hardened quine, etc., and explains many techniques for writing such programs.)
Bad news: It is written in Japanese.
I hope you can translate it into English and help me earn royalties.
Q. Language XXX is missing!
A. See the language inclusion criteria in detail. (In short, please create a deb package and contribute it to Ubuntu.)
See also :heart:.
Q. Does it really work?
A.
Q. How long did it take you?
A. Are you trying to cross the world line?
Q. The code does not fit in my screen!
A. Here you go.
Q. How was the code generated?
