If you really cared about readability , you'd put your commas where normal human beings put them . Instead of in a silly place like that . Prefering structur

  That is the (or at the very least a) normal place to put them in C++. Human beings use things differently in different contexts.

    I've been a professional C++ programmer for 24 years now, and neither I, nor anyone I've worked with over this period, used this ridiculous style.

      I've used it on larger teams where some enums for feature flags end up getting conflicts all the damn time when you add to the end because the last entry doesn't have a comma. This might be fixed in various languages/parsers by allowing a trailing comma (e.g. python). At the end of the day, clang-tidy, black, gofmt, rustfmt all the things and let's never talk about comma placement again.

        What if C++ actually allowed that comma? Because... it does.

          not everywhere, I often have a need for it in template arguments for instance for type lists: std::conditional< some_property< T, U, >, int, float, >; is a compile error, I really prefer std::conditional< some_property< T , U > , int , float >;

          That's only from C++11. The story I was telling you was from before then. $ cat test.cc enum Foo { FOO, BAR, }; int main(int argc, char** argv) { return 0; } $ g++ -std=c++98 -Wpedantic test.cc test.cc:3:5: warning: comma at end of enumerator list [-Wpedantic] 3 | BAR, | $ g++ -std=c++03 -Wpedantic test.cc test.cc:3:5: warning: comma at end of enumerator list [-Wpedantic] 3 | BAR, | ^ $ g++ -std=c++11 -Wpedantic test.cc

      It’s a Haskell thing, and while I don’t use it in any other language, it does look very neat and readable in Haskell.

        I thought it was an SQL thing.
        • jcelerier 5y ago
          It's because it's actually used in a lot of places because it makes sense
    • Zagitta 5y ago
      How many code bases have you actually worked on? I can tell you it's very common in constructor initializer-lists to the point that both the mozilla and webkit styles of clang-format does it.

    Trailing commas work just fine when the langage supports, well, trailing commas.
    • jcelerier 5y ago
      Having them aligned looks much better when you're used to it
      • masklinn 5y ago
        Anything seems better once you're used to it, even "not having toes".
        • jcelerier 5y ago
          well no, because I was used to trailing commas but this was creating more friction and was overall less pleasurable, that's why I switched to leading commas where it feels like an improvement
• masklinn 5y ago
  Prefix separators are an excellent way to avoid diff noise in langages without terminators (/ trailing comma support).

  This is silly for several reasons that I will list: * Programming is not prose, so we can temper our expectations. * Even in prose, some symbols belong on the left, and some belong on the right. * The example given is no less readable than the alternative. * It's more important to be consistent in style than correct to one person's opinion e.g. some people still batch edit source via macros and appreciate when curly braces are not in unexpected places.

  Happen very often in SQL codes :(
