There probably should be an even `n` test-case to make sure it's clear that those happen. (important as even/odd lengths mess with palindromization) (more) |

@#54151 Comments with shortened code are usually made with the intent of updating the answer (while letting the author review the changes). When updating the answer, you'd write `language, <strike>oldCount</strike> newCount bytes` in the header. (more) |

hm, I guess it could make sense to just not get rep from meta answers at all. Don't know what's better though. I guess most posts are ones where votes on answers just mean public consensus, for which getting rep doesn't make sense. (more) |

Pretty much nothing in this answer applies to libraries but not golfing languages. Golfing languages can too "cheat" by having builtins that immediately solve the challenge, and golfing languages are (at least in their start) used by just one person.
Adding a library to C results in a new language... (more) |

In an unfinished [completely random file](https://github.com/dzaima/Canvas/blob/master/files/implemented.md#palindromizator-defs) where it definitely doesn't deserve to be, with an unreadable description (where the described "basic overlap", "background overlap", and "mirror vertical" aren't even us...

@Lundin The importing of the library, if required in the code, is required in the answer. (reasoning being that the import probably requires using `.` in each answer anyways, and if it doesn't, it's polluting the global scope with arbitrary functions which I definitely wouldn't allow) (more) |

@JoKing fwiw, unary actually only scores 1 as it only allows zeroes in its source. Lenguage is the one getting 256. Don't think it's worth it doing anything about this. (more) |

@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) |

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 ...

@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) |

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) |

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...
