havelock posted:C# enums accept arbitrary ints for versioning reasons. Sum types force you to handle all cases at compile time, enums (in C# anyway) explicitly don't. As long as you have a default: in your case statement then you're fine.

Soricidus posted:exhaustiveness checking is the best thing about java enums. if i add a new member, the compiler will tell me what code needs to be updated to handle it. default clauses just hide the problem, like why are you using a statically typed language if you don't want static checks Because adding an explicitly new value shouldn't force all of your library consumers to recompile. (I don't want to hear wrong opinions about checked exceptions again, but do note that this is a consistent choice in that respect) havelock fucked around with this message at 20:34 on Mar 11, 2014 |

adding a new enum value is change in the api and everyone should be made aware. that's the entire point of static typing. if you don't want that to happen just go back to using public static final int.

Shaggar posted:adding a new enum value is change in the api and everyone should be made aware. that's the entire point of static typing. Which mode should I open this file in? Guess what - someone added a new mode that isn't the one I was asking for anyway - gotta recompile. If you are changing semantics, you should be changing your version number significantly anyway, so callers would have to explicitly opt in.

yeah you should totally up the version number for sure but anyone who upgrades should also be warned about changes whenever possible. manual documentation will be ignored and/or wrong, so its best to let the compiler inform them

DukeDuke posted:my "Programming Language Concepts" professor is teaching us agda, a functional language even more useless than the haskell it's built on. on a recent student eval form he actually asked "should this class switch to haskell in the future?" where do you go to school? (is it... duke?) agda would generally be taught in a graduate level class devoted entirely to programming dependently typed proof assistants. and if he wants to teach that, he should use coq, because it's more mature

prefect posted:hey, i use that software I did manage to build and run it. it works fine except for trying to put 9 rows in a 2x6 grid layout which makes it crash. and a possibly unrelated crash when it's compiled in release mode. the UI is clunky and the code is messy so I'm not going to try and fix it any soon, but I'll try to be a good citizen and contribute patches for the worst issues Malcolm XML posted:yeah c++ doesn't have a specified abi so everybody has to recompile poo poo when apple switched to clang++ fulltime there is an ABI specification and both g++ and clang are following it to some degree because they are like 99.9% compatible, but libraries can still screw up if they do conditional compilation in ways that produce different object layouts for different, binary-compatible compilers. there are patterns to make C++ libraries robust against that kind of issue but  and you know that if you man up and do it, some sperglord is going to put your library through a benchmark to mathematically prove that it's bad and you're bad and you should feel bad

pretty soon you end up just reinventing COM... "copy-pasting method wrappers is really tedious, why not just allocate all this stuff on the heap and use smart pointers? of course, then you have to have reference counting semantics and oh my god what am i doing i know where this road leads" at least everything on linux uses the same libc, though i bet statically-linked proprietary software that exports a plugin API turns into a freakshow real fast

Mr Dog posted:at least everything on linux uses the same libc, though i bet statically-linked proprietary software that exports a plugin API turns into a freakshow real fast the linux linker is not that stupid. it technically supports rpath like solaris. distribution packages never need the feature but it means proprietary software is almost always dynamically linked simplified explanation linux-style linking
solaris-style (sane) linking
linux technically supports the latter, better system and vendors are usually smart enough to use it when they are not, that is when the suffering begins. LD_PRELOAD abusers should be shot
