As a bonus, one that doesn't call unsafe stuff? 23:08:33 tmapper15 = map (map (...(map trans)...)) 23:08:50 This is straightforward, but a little hard to read sometimes, and a bit crufty 23:09:17 What'd be nice if you could just say tmapper[n] = map[n] trans 23:10:01 map[n] func arr maps func over the elements of arr at the nth nesting level 23:10:41 Of course, map f l = map[1] f l 23:10:46 I'm not sure how the semantic rules of rust about undefined behavior work. Can I just ptr.write or ptr.copy from an int32 to a float32 and read the float32 without invoking undefined behavior? 23:11:05 It'd make the syntax of the language a little less pure, but it'd make code look better 23:11:08 b_jonas: what language? 23:11:16 coppro: rust 23:11:22 b_jonas: I dunno then 23:11:47 (Which is weird, given that it seems that x => y -> bad x => bad y, but it isn't true here) 23:12:48 b_jonas: http://stackoverflow.com/questions/26163272/strict-aliasing-in-rust 23:13:15 FireFly: template haskell is a bit scow 23:13:27 ^ 23:13:32 I still don't know what scow means, but I agree 23:13:43 @google garbage scow 23:13:44 https://en.wikipedia.org/wiki/Garbage_scow 23:14:07 hppavilion[1]: that sort of thing is what control.monad.*.class is for 23:14:13 I agree, template Haskell is a bit scow. 23:14:29 pikhq: i'm a lens maintainer now. help. 23:14:42 :( 23:14:44 hppavilion[1]: you could also do it with a newtype 23:14:45 coppro: I really don't want to break aliasing, I think getting or setting the representation of IEEE floats should be a builtin (but possibly rarely used) arithmetic op that the float32 module of the standard library should just export, but alas, it seems there's no such function. 23:15:22 b_jonas: sounds like transmute can do it 23:15:28 * pikhq is curious if rust has reasonable floating point semantics. 23:15:31 coppro: even this way, the rust standard library functions for float32 look way saner than the obsolate nonsense some languages try to provide, with no frexp or an exception when you divide on zero. 23:15:51 The *most* reasonable being "literally IEEE", of course. 23:15:54 ^ 23:15:59 coppro: Are you a maintainer or do you just have a commit bit? 23:16:05 shachaf: commit bit 23:16:08 Though I'll accept ISO C's semantics (as opposed to GNU C's). 23:16:24 Will you accept gnusto semantics? 23:16:24 I don't consider myself actively responsible for it 23:16:29 pikhq: what are the differences? 23:17:21 coppro: When using x87, GNU C will flush intermediate values from floating point computations to the stack by storing a double or float representation on the stack. Which imposes double rounding. 23:17:23 pikhq, iirc, Rust has a very cautious IEEE 23:17:54 pikhq: why does that double round? 23:18:13 pikhq: which iso C semantics? the c89 or the c99 ones? and with which settings if the latter? 23:18:26 Because all floating point operations are rounded, and on x87 the only precision it has is 80-bit float. 23:18:38 ahh 23:18:44 b_jonas: ISO C99 with the semantics in the amendment defining IEEE semantics.. 23:18:52 is that not ISO C semantics? 23:19:01 -!- p34k has joined. 23:19:05 No. 23:19:06 have to match the abstract machine 23:19:26 ISO C semantics say that the result of an operation on doubles is a double_t. 23:19:39 And on x86 a double_t is an 80-bit float. 23:19:47 (or "long double") 23:20:04 GCC implement it this way if you pass -std=c99. 23:20:05 sorry, it's too late for me to think deep about floating point semantics. I did the research once, and wrote it down on a dense ugly handwritten paper which doesn't cover even half of it. 23:20:06 -!- Sgeo_ has joined. 23:20:11 But not -std=gnu99. 23:20:28 * coppro looks at the appendix 23:20:43 In GNU C you get double rounding *basically* when the optimizer sees fit. 23:22:38 ok wait 23:22:47 I re-read what the docs says 23:23:17 and it seems to me that the rust rules do permit to copy the memory from an int32 to a float32 or back 23:23:49 which is also why mem::transmute (which coppro kindly pointed me to) should work 23:24:05 and that can probably be optimized fine 23:24:24 so I can wrap that to define the four float-int reinterpret functions 23:24:32 coppro: thanks for the nudge 23:24:36 http://port70.net/~nsz/c/c99/n1256.html#5.2.4.2.2 Here's the relevant part of ISO C99 describing float_t etc. 23:24:59 *This* bit is independent of whether or not you implement IEEE floats. 23:25:18 Erm, wait... 23:25:31 double_t is in math.h, sorry. 23:25:46 pikhq: oh, I see, FP_CONTRACT 23:26:02 (obviously rust still has a lots of rules about what you're permitted to do with pointers, but accessing memory that you're normally permitted to read as some other type is allowed, as long as you only write allowed values, but any bit pattern is allowed for an u32 so that's fine) 23:26:44 FLT_EVAL_METHOD describes the actual behavior of the floats, though. 23:27:58 FP_CONTRACT is a pragma 23:28:01 Yeah. 23:28:28 GCC's implementation of floating point is slightly off. For instance, it apparently doesn't do that pragma. 23:28:51 pikhq: no compiler does that pragma, neither gcc, nor msvc. both have some other ways of controlling the same thing though, in later versions 23:29:16 It's a shame. The ability to get floating point stuff working reasonably is, uh, why science people still use Fortran. 23:29:19 pikhq: the problem is, the gcc equivalent can't be changed as quickly in blocks, but only to function level 23:29:56 -!- hppavilion[1] has quit (Ping timeout: 244 seconds). 23:30:05 pikhq: sure, but you can get them to work reasonably in gcc and msvc, you just have to know the magic compiler-specific incantations, and also the _default_ settings are sane for both 23:30:19 (at least if you use at least -std=c99 as a base, and not an old compiler) 23:30:45 Yes, the default settings *in -std=c99 on recent compiler versions* are at least sane. 23:30:47 those magic incanatations are part of my handwritten paper, which incidentally I really should make a photo and backup of now 23:30:54 Sufficiently so that for 99% of things they're what you actually want. 23:31:23 The problem being, of course, that -std=c99 isn't default, and getting the other things you might want aren't supported. 23:31:26 pikhq: to be fair, the choice of a pragma is a stupid design 23:31:42 Not gonna disagree. 23:32:02 coppro: what? why is that a stupid design? 23:32:08 b_jonas: what is float f = a + \\ #pragma SOMETHING \\ b; 23:32:11 coppro: at least in C99, where you have _Pragma 23:32:33 coppro: no, but you can put _Pragma in brace blocks locally, even in a macro 23:32:47 coppro: not in the middle of an expression, but in a brace block between statements 23:33:30 b_jonas: yes, _Pragma statement makes sense, except that it's defined in terms of preprocessor 23:34:06 And ostensibly the preprocessor is a phase independent of the rest of compilation. 23:34:10 Except of course it isn't. 23:36:03 coppro: no, that's just a historical accident, where improving the language is important, but everyone's lazy to rewrite the standard to use a more readable terminology, so the preprocessor is brought into the picture mostly unnecessarily. It happens all the time with changing M:tG rules too, but it's worse with the C and C++ standards. 23:36:06 pikhq: of course it is 23:36:11 pikhq: haven't you heard of _Generic? 23:36:12 :P 23:36:21 b_jonas: C is *really* bad 23:36:24 C++ is not nearly so bad 23:36:45 at least in this regard. C++ has other issues. 23:36:57 C++ is great. 23:36:59 I have friends who've been to both committees though 23:37:06 C++ committee is awesome 23:37:09 C... not so much 23:37:23 pikhq: also, because of historical reasons, the defaults even with -std=c99 aren't entirely reasonable, because they default to math functions setting errno, which is a complete waste, but in gcc you can -fno-math-errno to get the saner behavior. 23:38:41 b_jonas: that's standard though, isn't it? 23:38:56 coppro: C99 allows either, and defines a macro to tell you 23:39:30 coppro: but I for one don't want to have the compiler emit an expensive conditional set for a thread-local variable every time I lrint an number. 23:39:45 -!- p34k has quit. 23:40:32 yeah no kidding 23:41:04 coppro: the C++ committee hasn't caught up with the improvements in C. They're reluctant to take the changes because half of them is good (eg. floating point stuff) and half of them is bad (variadic arrays, and that "safe" standardd library stuff). But in practice that doesn't matter, because gcc still implements this stuff for C++ too (except there are a few conflicts, like how complex is a macro in C but an identifier in C++, etc), and even msvc is slo 23:41:07 -!- hppavilion[wc] has joined. 23:42:06 Also, I'd like an lrint and lrintf variant that returns int32_t instead of a long 23:42:15 and a pony too 23:42:35 Here's an idea for AOP 23:44:06 I should make a slow interpreter for a high-level language that exposes ALL the sane integer and floating point and complex floating point operations on all types there are, because I've had enough of no language exporting the full set, even though C comes quite close. 23:44:12 By the way, as for floating point stuff, 23:45:08 I understand why the C++ committee added an extra function (not in C) that returns the squared norm of a complex number. But for the love of HNA, WHY DID THEY HAVE TO NAME IT norm? 23:45:53 That's just so confusing! There are numerics-connected libraries that use the identifier norm to mean a non-squared norm, and when I use norm in two such clashing meanings in the same program it just gets horrible. 23:46:00 WHY COULDN'T THEY FIND A BETTER NAME? 23:48:19 coppro: I suspect a lot of this has to do with a lot of the C committee pretending that certain vendors' opinion on things matter even when they haven't even bothered implementing C99. 23:48:53 For instance, the "safe" standard library stuff comes courtesy of Microsoft, because Microsoft is on the committee even though to this day they haven't implemented the *17 year old* C99 spec. 23:49:18 (and they have some pretty notable violations of C90 as well...) 23:49:49 pikhq: yeah... 23:49:56 pikhq: I didn't ask 23:50:20 but I wouldn't be surprised if it wasn't a little like hardware standardization 23:50:33 which is a competitive, rather than collaborative, process 23:50:33 It's honestly worse than IBM's presence on the C++ committee because, while they insist on some frankly silly things sticking around because of mainframe, at least they *implement* the damned thing on the systems they want to keep supporting. 23:50:38 -!- oerjan has joined. 23:50:45 pikhq: trigraphs are gone 23:50:58 In the next revision of C++, but not the current one. 23:51:12 yeah 23:51:14 C++17 is going to be great. 23:51:14 Giving IBM time to stop using trigraphs. 23:52:09 shachaf: file system library! 23:52:16 Are they just replacing them with digraphs? 23:52:24 coppro: Variadic fold expressions will be good. 23:52:26 pikhq: digraphs don't cover everything trigraphs did 23:52:27 Ah, yes, it seems they are. 23:52:29 Or whatever they end up with. 23:52:31 shachaf: yeah, those are sweet too 23:52:42 Yes, but digraphs cover everything that IBM needs. 23:52:44 pikhq: basically IBM said "ok, fine, whatever, we'll just maintain our own compiler" 23:52:49 coppro: Writing variadic template code is such a mess. 23:53:03 shachaf: yeah... 23:53:14 The only *actual* problem is some of the digraph-encoded characters on EBCDIC codepages vary encoding depending on the codepage. 23:53:16 Do you have any fun variadic template puzzles? 23:53:25 But they all exist in real-world EBCDIC codepages. 23:53:34 shachaf: tbh if they were redesigning templates they'd probably do it very different 23:54:27 pikhq: yes, but funnily, I think the floating point control pragmas come from microsoft too 23:54:51 -!- HackEgo has quit (Ping timeout: 276 seconds). 23:55:17 eek 23:55:45 parallel STL is sweet too 23:56:06 and string_view 23:56:16 pikhq: also, in msvc 2015, they actually implement once-init local statics and constexpr and alignas and alignof and a lot of other C++ stuff (but not everything). 23:56:18 coppro: Why doesn't std::tuple expose a tail tuple explicitly? 23:56:26 Wouldn't that be a better API? HList-style. 23:56:30 -!- boily has joined. 23:56:36 std::tuple is already pretty much HList, I guess. 23:56:48 I still really don't like their compiler, but it's at least getting less bad. It's just that it's still like five years obsolate compared to gcc or something. 23:56:52 shachaf: because it would require explicit construction 23:57:06 b_jonas: MS is moving to clang 23:57:15 So like the msvc five years into the future will be able to compile all my code. 23:57:20 Maybe I should look at how it's implemented. 23:58:09 coppro: so I've been told, but I don't buy it. just look at it, the original reasoning was that they'd have to rewrite half of msvc just to implement constexpr. but now they support constexpr in msvc 2015. so what gives? 23:58:43 b_jonas: are you sure that the frontend you're using there isn't clang? 23:58:44 coppro: if "moving" means they'll use clang to compie their stuff instead of the shit they sell, then sure 23:59:10 @massages-loud 23:59:10 You don't have any messages 23:59:18 b_jonas: no, visual studio is moving to clang as its frontend. 23:59:26 -!- Warrigal has changed nick to tswett. 23:59:38 So let me see if I can come up with an ordinal number notation. 23:59:47 coppro: no way... if it is, then it's a modified version of clang that gives worse error messages than gcc 1.95 gave 23:59:53 https://blogs.msdn.microsoft.com/vcblog/2015/05/01/bringing-clang-to-windows/ 23:59:59 b_jonas: ah, then I can't explain it
