Using your language of choice, golf a quine.

A quine is a non-empty computer program which takes no input and produces a copy of its own source code as its only output.

No cheating -- that means that you can't just read the source file and print it. Also, in many languages, an empty file is also a quine: that isn't considered a legit quine either.

No error quines -- there is already a separate challenge for error quines.

Points for:

  • Smallest code (in bytes)
  • Most obfuscated/obscure solution
  • Using esoteric/obscure languages
  • Successfully using languages that are difficult to golf in

The following Stack Snippet can be used to get a quick view of the current score in each language, and thus to know which languages have existing answers and what sort of target you have to beat:

anyfix, 29 bytes


Try it online!

Another half finished golfing language. This is rather longer since the string quoting uses different starting and ending quotes, both with large ordinal values. There's probably a shorter way that I'm missing.


“8221"’OƥO«"ƥ«”                    Push string
               8221                Push 8221
                   "’              Duplicate and decrement
                     Oƥ            Convert to character and print (starting quote)
                       O«          Convert to character and swap with string
                         "ƥ        Duplicate string and print
                           «       And swap end quote back to top of stack
                                   Implicitly print from top of stack to bottom

Atari BASIC. 4 bytes

1 L.

Well known since the release of the language, and the result of two quirks of this BASIC dialect. Most BASICs only let you run outside commands in immediate mode, but Atari BASIC allows a line number here. Secondly, there's a full list of abbreviations for the common commands.

  • \$\begingroup\$ I thought about entering this in common 8-BIT basic, but I am not sure about this rule: "No cheating -- that means that you can't just read the source file and print it", so my entry is non-competing and just for fun. \$\endgroup\$ Jun 3, 2023 at 16:51

Pyret, 72 61 bytes

a="\nprint('a=' + torepr(a) + a)"
print('a=' + torepr(a) + a)

No, I can't remove the spaces surrounding the +

I'm learning a little Pyret because my brother is taking a coding class where this is being taught and he wanted me to help him learn.
