This is an answer chaining puzzle, where each answer must add on to the last.

The \$n\$th submission must output its own source code in the \$n\$th language and the \$n−1\$ languages before it.

A language can be either a dialect or a major version of a language, so Python version 2.121 is only counted as version 2 and Common Lisp and Clojure are considered different languages. This excludes compiler flags.

You can post 2 answers in a row, but have to use different languages.

The winner of this puzzle is the person to submit the second-to-last quine if there have been no new quines for a week. The aim of this puzzle is to go on as long as it can, so if you want the green tick, you'll have to respect that.

Have fun.

    \$\begingroup\$ But other than that, creative and cool challenge! (Just a note, don't be offended by the downvotes, they are just indicating whether it would be good for the site in it's current form). Also, "output its own source code in n different languages" may seem a little bit too hard for an answer-chaining questions, so you may want to change that to the current language instead of all the previous languages. \$\endgroup\$ – MilkyWay90 Mar 15 '19 at 0:59
  • \$\begingroup\$ Well actually re: scoring, one thing you can do is copy the other polyglot-chaining problem, which has a scoring metric based on both number of languages and code size \$\endgroup\$ – ASCII-only Mar 15 '19 at 6:25

    \$\begingroup\$ Are there any rules on one person posting two answers in a row? \$\endgroup\$ – Jo King Mar 16 '19 at 7:11

><>, 187 bytes

var s=1
<0?"":"var s=1{0}<0?{1}{1}:{1}{3}{1};Write(s,(char)10,(char)34,(char)39,s)//.1+d*fao;!?l{1}var s=1{1}ar*3dr{2}";Write(s,(char)10,(char)34,(char)39,s)//.1+d*fao;!?l"var s=1"ar*3dr'

Try it online!

Try C# Online

Let's add a 2D language, why not?

  • \$\begingroup\$ Just for your info: if you plan to submit again, the quine must only work properly for this lang and another one of your choice, while still including the C# code. \$\endgroup\$ – Andrew Mar 15 '19 at 13:42
  • \$\begingroup\$ No. You have to use other people's languages, leave all the previous stuff intact, while adding on your thing. However, the result only needs to work like a quine for whatever lang you choose next and the one in the last submission. If I added something as the third last submission, the quine could work like mud in my language but work perfectly in yours and in the last one. \$\endgroup\$ – Andrew Mar 15 '19 at 13:50
  • \$\begingroup\$ I'm reverting it to the polyquine challenge. \$\endgroup\$ – Andrew Mar 15 '19 at 14:03
  • \$\begingroup\$ I get 1 What do you want 0/0 to be? What do you want 0/0 to be? when I try running this in Befunge, lol \$\endgroup\$ – MilkyWay90 Mar 16 '19 at 1:01
  • \$\begingroup\$ @MilkyWay90 Yeah, if you're going to add Befunge-98 to this, then you're either going to have to get rid of the "s in the C# code, or have to use nk', e.g. like this quine \$\endgroup\$ – Jo King Mar 16 '19 at 2:17

C# (Visual C# Interactive Compiler), 63 bytes

var s="var s={0}{1}{0};Write(s,(char)34,s)";Write(s,(char)34,s)

Just to start it off.

  • \$\begingroup\$ I've written a polyglot with ><> (Try it online!), but I can't post it since it breaks the 50+ chars rule :( \$\endgroup\$ – Jo King Mar 15 '19 at 0:31
  • \$\begingroup\$ @JoKing It also seems to break the no STDERR rule ("something smells fishy...") \$\endgroup\$ – MilkyWay90 Mar 15 '19 at 1:00
  • \$\begingroup\$ @JoKing it isn't impossible, see here. Granted, the two languages are basically the same, but you know, it's the implementation that counts \$\endgroup\$ – Embodiment of Ignorance Mar 15 '19 at 2:28

    \$\begingroup\$ Okay, but try making a polyquine with a language that isn't C# and see how far you get. (P.S. I've always been annoyed with the implementation vs languages ruling when it comes to polyglots. You wouldn't post a program and say "This is a polyglot with all 16 implementations of the language, because all of them work exactly the same". It's only really a polyglot if none of the languages do the exact same thing with the program) \$\endgroup\$ – Jo King Mar 15 '19 at 2:46

    \$\begingroup\$ An example of a bullshit polyglot is your previous answer here which "scored" infinity, because the "languages" had literally no difference between them \$\endgroup\$ – Jo King Mar 15 '19 at 2:47
