This is a Ruby program that generates Rust program that generates Scala program that generates ...(through 128 languages in total)... REXX program that generates the original Ruby code again.
(If you want to see the old 50-language version, see 50 branch.)
If you are using Ubuntu 21.04 (Hirsute Hippo), you can perform the following steps.
First, you have to type the following apt-get command to install all of them.
$ sudo apt-get install afnix algol68g aplus-fsf aspectj asymptote \
ats2-lang bash bc bf bsdgames bsh clisp clojure cmake coffeescript \
dafny dc dhall elixir emacs-nox erlang f2c fish flex fp-compiler \
fsharp g++ gambas3-scripter gap gawk gcc gdb gdc \
generator-scripting-language genius gforth gfortran ghc ghostscript \
gnat gnu-smalltalk gnucobol gnuplot gobjc golang gpt groovy guile-3.0 \
gzip haxe icont iconx intercal iverilog jasmin-sable jq julia ksh \
libpolyml-dev lisaac livescript llvm lua5.3 m4 make maxima minizinc \
mono-devel mono-mcs mono-vbnc nasm neko nickle nim node-typescript \
nodejs ocaml octave openjdk-11-jdk pari-gp parser3-cgi perl php-cli \
pike8.0 polyml python3 r-base rakudo ratfor rc regina-rexx ruby \
ruby-mustache rustc scala scilab-cli sed slsh spin squirrel3 \
surgescript swi-prolog tcl tcsh valac vim xsltproc yabasic yorick zoem \
zsh
Then, build the bundled interpreters.

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.
Simply build the image and run a container as follows:
$ docker build -t qr .
$ docker run --privileged --rm -e CI=true qr
Note: you need to run in privileged mode otherwise the maxima command will fail.
If you want to check generated files, you can mount the local directory in the Docker container (but keep using 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 qr
You may find instructions for 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.

Note that some languages are not available in Ubuntu (marked as N/A).
This repository includes their implementations in vendor/.
See also vendor/README in detail.
A. Take your pick.
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 an 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 into English and help me earn royalties.
A. See the criteria for language inclusion in detail. (In short: please create a deb package and contribute it to Ubuntu.)
