@Lundin the tag can be used for answer standards, and isn't restricted to code-golf only either though. And calling them "rules" isn't preferable either, as they are only defaults, allowed to be overridden at will by the challenge specification. I'm now more leaning towards the "defaults" tag name (more) |

@Lundin Code golf is about using any and all tools you have to achieve the shortest byte count in a specific setting (language, implementation, OS, etc). As far as this site is considered, you can consider a non-standard C dialect as not at all related to C beside the name, and competing with it as p... (more) |

| Question | — |
How do we handle standardizing things? Code golf, being about exploiting things, often brings about many questions about edge cases. Since we don't want each challenge to have to deal with all problems again and again, it makes sense to standardize some defaults for questions about various topics (including, but definitely not limited to,...

Ah, I misunderstood what you were trying to say with freestanding mode. Sure, you can make an answer as such, if you can actually find a system that will run the function `x` on startup. But at that point you could just say your answer is a function (a meta post on what's a valid program, if there we... (more) |

(really that C hello world answer _should_ be specifying that the answer is e.g. "C (GCC 10.2 on Linux)" or equivalent, but that'd be boilerplate on most C answers so it's often left out, plus it works just fine on any GCC/clang versions and probably on most OSes) (more) |

'you can't prove that something isn't UB with "it seems to be working just fine"' I have the binary of GCC. Assuming it compiles deterministically, I _could_ actually prove it outputs `"Hello, World!"` in at least one version of it. And my answer proposes that that's all that matters here. (more) |

"just set gcc to freestanding mode" That's applying a completely arbitrary change to my answer.. If we now allow you to do anything you want with the system running it, you could also define `puts`, `printf`, etc to call `exit(1)` and now I can never ever print anything and now noone can ever answer ...

"it produces numerous diagnostics" but I still get a binary, and it outputs the required string. Warnings completely don't matter. Sure, it's not valid standard C, but it is completely valid & good "GCC/clang C". (more) |

@Lundin A function is just allowed as a form of an answer (as an alternative to a full program). e.g. otherwise you are restricted to only a single string I/O (stdout/stdin) which is often extremely limiting (e.g. you'd need to have a JSON parser equivalent to take, as an input, an array of arrays of...

@Lundin this answer is only about the specific problem of allowing functions as answers. My answer deals with the requirements for the actual language - you have 2 "places" where `stuff()` could be defined - your answer code whose bytecount you count, and the language you're answering in (whose size ...

(and if you want to write strictly compliant programs, go ahead (under, say, the language name of "ISO C11")! It's a separate "language", so you can still win in the competition of ISO C11.) (more) |

@Lundin Also UB doesn't matter if the answer _works_, though it's a good question how much "crashing and burning" can be allowed (certainly not to the point of time travelling before the output was printed, but beyond that it's complicated). (more) |

"and now I will win every competition" The specific compiler is part of the language, so, assuming a challenge with the "Shortest byte count _per language_ wins" criterion, you might win on that obscure C compiler's C version, but won't actually compete with GCC/clang. (more) |

"will not compile on a single reasonable C compiler" - it works fine on GCC and clang without additional arguments, so I have no clue where you got that from. It may not be standards compliant, but it's valid GCC/clang code, and, per my definitions, that's fine as one working implementation is enough... (more) |

@Lundin "Where is this written?" Here. This site was just started, and obviously we haven't gotten around to re-writing the dozens of standards posts. This one is progress in starting doing that. (more) |

A: What are the rules of programming language compliance? If there exists something (reasonable) that can run it, it's valid. This includes obscure, non-standards-compliant compilers (though this should be specified in the answer if needed). So any posted program on a standard code-golf question must actually be executable and should (at least theoretica... (more) |

Is there any delay required between the frames? As-is, any reasonable solution would easily get thousands of frames per second, probably with the screen refreshing mid-frame too. (unrelatedly, for reference, clearing the screen with ANSI escapes appears to work as just `"\x1Bc"`) (more) |

"if and only if it cannot clear the screen" Any language that can output arbitrary bytes to stdout can "clear the screen" in a unix terminal with ANSI escape codes. (more) |

[Example 1](http://oeis.org/A333977) - its first number doesn't fit in a 32-bit integer, so we, by outputting nothing, always identify it correctly.

You should mention that there must actually be a valid input corresponding to a claimed sequence (otherwise every answer is valid on _at least_ a thousand sequences); Also, the constant sequences continue up to 32 - `A007395 A010701 A010709 A010716 A010722 A010727 A010731 A010734 A{010850-010871}` (t...

Canvas doesn't have English compression, so it's as long as just the string constant itself. (more) |
