The idea is not that the input would come into the program through function parameters, but that the function would be called from within a larger program, and the program would call it using arguments as input. This allows competing to find the shortest function that solves a problem, rather than to... (more) |

> This is under the assumption that in a function solution, input has to be passed as parameter and output through the return value
I would be interested to hear any alternatives you considered, and whether you think they would make good defaults for input and output for function solutions.

One thing I forgot to ask about in the Sandbox:
> The program need not do anything meaningful but must compile cleanly (no language syntax or constraint violations etc)
I assume from this that warnings that do not prevent compilation/interpretation are acceptable. Either way, it might be helpfu... (more) |

A: Category migration and the sandbox Sandbox votes should give no reputation I believe this is already the case, but for completeness: I agree that neither upvotes nor downvotes on Sandbox posts should affect reputation. Although I would encourage everyone to sandbox every challenge idea, I think the benefits of rewarding sandbox... (more) |

Since there are a few separate questions here, I can see a benefit to posting one idea per answer. This way, I can post an idea about whether sandbox votes should count and an idea about whether to reset votes, and one can be upvoted and the other downvoted. If they were posted in a single answer, th... (more) |

Post edited: Add TODO for checking choice of sphere makes little difference |
— | 6 months ago |
| Comment | Post #292000 |
Since all of the surface patterns in the test cases are formed by overlapping spheres to take advantage of this effect, I will double check before posting that either choice of which sphere's colour to display gives sufficiently similar output images. (more) |
— | 6 months ago |
| Comment | Post #292000 |
When 2 spheres A and B overlap, there are 3 types of overlapping points:
- The surface of A is inside the surface of B (so the nearest intersection will be B).
- The surface of B is inside the surface of A (so the nearest intersection will be A).
- The 2 surfaces meet along a circle (infinitely th... (more) |

I've now edited the Output section to mention this - thank you.

Good question.
Short answer:
I should make explicit that the code can choose either. I will edit accordingly.
Waffle:
The only case where I'd expect this to make a noticeable difference to the resulting image is when two spheres are identical in both centre and radius, which could cause o... (more) |

Since this uses the same regex as your JavaScript answer, the same bug applies as described in [Peter Taylor's comment there](https://codegolf.codidact.com/comments/thread/9801#comment-24662). (more) |

| Comment | Post #291048 |
I hadn't thought of that. I see no reason why not. I've now edited to explicitly allow lower case, provided that your output is in the same case as your input (apart from the indication that an input is valid, which can be any consistent value), and I've added the same test cases in lower case.

Yes there is more than 1 way to get the correct answer. I'm interested to see which way will turn out to be shortest in different languages. (more) |

A: Preferred length limit for Code Golf posts 65,535 The database field can already handle up to 65,535 (216 - 1) characters. Same for all post types and categories I don't see a need for different limits for questions and answers, or for different categories. Challenges I sometimes find the current 30,000 character limit restrictive,... (more) |

| Question | — |
Preferred length limit for Code Golf posts Currently the maximum number of characters for a Codidact post is 30,000. However, at some point this may be configurable per community (or perhaps per category). There is a GitHub issue for Configurable length limits for content. If this configuration option is implemented, what limit would you l... (more) |

Good point about combining with a library. That seems to make this inclusive of more languages. (more) |

| Comment | Post #292376 |
Personally, I expected that "constants" would be referring to the names of built in constants, such as `PI` or `SQRT3`.
However, since the names of such constants also count as "identifiers", it might help to have an explanation of each term to remove ambiguity. (more) |

| Comment | Post #292376 |
> the source itself contains and iterates through the whole English alphabet
Here "iterates through" sounds like the code when running has to process the alphabet, which does not appear to be the case from the example code. My best guess at the intended meaning is:

I don't know if there are languages for which not every letter is included in a language keyword, function name, constant, or identifier. If there are, then it sounds like these languages would be unable to compete. I have 2 thoughts on this:

In response to a comment on the challenge, I've decided to make the input format more flexible. This leaves your current answer just as valid as before, but I'm letting you know because it is likely you can use the added flexibility to reduce your score. (more) |

Allowing an array of digits (as integers rather than characters) would bring the python answer down to 27 bytes.
I did intend this as a very quick challenge, so I'm now considering allowing input as any of:
- a number (such as integer or floating point number)
- a string
- an array of character... (more) |
— | 7 months ago |
| Comment | Post #292354 |
Actually allowing input as a string would only take the python answer from 37 bytes to 32, so I was probably overstating "bulk of the challenge". (more) |

| Comment | Post #292354 |
Oh good point. I hadn't thought of that. Usually I like input formats to be flexible as long as the input format doesn't constitute preprocessing. In this case I feel like separating the input into digits is the bulk of the challenge.
I've currently specified input as an integer, so the existing p... (more) |
