| 00:09:18 | FromDiscord | <Elegant Beef> we're at `100.320991455078` |
| 00:10:58 | FromDiscord | <Rika> nice |
| 00:11:00 | FromDiscord | <Rika> congrats |
| 00:11:01 | FromDiscord | <Rika> told you |
| 00:12:08 | FromDiscord | <Elegant Beef> Fuck yea works on objects! https://media.discordapp.net/attachments/371759389889003532/731301759401721958/unknown.png |
| 00:12:20 | FromDiscord | <Elegant Beef> Told you rika! I told you! 😛 |
| 00:13:04 | FromDiscord | <Elegant Beef> @Recruit_main707 so congrats you solved your object issue |
| 00:15:51 | FromDiscord | <Rika> @Elegant Beef now try saving that bitstring and using it on next run |
| 00:15:58 | FromDiscord | <Recruit_main707> es |
| 00:16:07 | FromDiscord | <Rika> the string will either show garbled data or segfault your program |
| 00:16:12 | FromDiscord | <Recruit_main707> Dammit autocorrector |
| 00:16:14 | FromDiscord | <Rika> im almost sure of it |
| 00:17:32 | FromDiscord | <Elegant Beef> Why are you so mean |
| 00:17:48 | FromDiscord | <Rika> am i right? |
| 00:17:54 | FromDiscord | <Rika> lol |
| 00:17:58 | FromDiscord | <Elegant Beef> You couldnt just let me be hpapy |
| 00:18:00 | FromDiscord | <Rika> you're saving the pointer to the data is why |
| 00:18:00 | FromDiscord | <Elegant Beef> (edit) 'hpapy' => 'happy' |
| 00:18:27 | FromDiscord | <Rika> it works in the example you sent since the pointer never changes |
| 00:20:14 | FromDiscord | <Elegant Beef> Ah i see |
| 00:20:36 | FromDiscord | <Elegant Beef> So i didnt ever do what i want is what you're saying |
| 00:20:42 | FromDiscord | <Elegant Beef> Nice |
| 00:21:34 | FromDiscord | <Rika> you need to add a special case for objects, iterating through the thing (+ containers too i assume) |
| 00:22:23 | FromDiscord | <Rika> and this kinda isnt safe for network transmission either unless you use TCP since a dropped packet would fuck you over really damn hard |
| 00:24:36 | FromDiscord | <Elegant Beef> I mean i only intend on sending primitive data types in a byte arrayt |
| 00:24:37 | FromDiscord | <Elegant Beef> (edit) 'arrayt' => 'array' |
| 00:24:56 | FromDiscord | <Elegant Beef> But vectors are primitive data types |
| 00:25:03 | FromDiscord | <Elegant Beef> 😄 |
| 00:26:14 | FromDiscord | <Elegant Beef> Then what the hell is the proper way to convert datatypes into a byte array |
| 00:26:15 | FromDiscord | <Elegant Beef> 😄 |
| 00:27:57 | FromDiscord | <Rika> using a protocol? like protobuf or bson or so |
| 00:28:03 | FromDiscord | <Rika> i mean a |
| 00:28:09 | FromDiscord | <Rika> what do you call it |
| 00:28:17 | FromDiscord | <Rika> a data serialization thingy |
| 00:28:20 | FromDiscord | <Rika> names are hard |
| 00:28:21 | FromDiscord | <Rika> w/e |
| 00:28:34 | FromDiscord | <Elegant Beef> Yea but i mean in nim we dont have a way to marshal to the byte array? |

| 00:35:17 | FromDiscord | <Elegant Beef> > The serialization format uses JSON |
| 00:36:23 | FromDiscord | <Rika> get to programming bson then or smth i guess |
| 00:36:51 | FromDiscord | <Elegant Beef> I mean i just need the bytes |
| 00:37:03 | FromDiscord | <Elegant Beef> I dont need to use any format |
| 00:37:11 | FromDiscord | <Elegant Beef> My macro was making the format |
| 00:37:13 | FromDiscord | <Rika> what you are doing is making a format |
| 00:39:14 | * | hyiltiz quit (Ping timeout: 240 seconds) |
| 00:39:29 | FromDiscord | <Elegant Beef> Well im making many formats |
| 00:39:46 | FromDiscord | <Elegant Beef> But the point is i dont really need to use anything, i just need the underlying bytes |
| 00:40:47 | FromDiscord | <Elegant Beef> Ah |
| 00:40:48 | FromDiscord | <Rika> i dont understand how this would be useful in any useful usecase but ok |
| 00:40:52 | FromDiscord | <Elegant Beef> string stream is the winne |
| 00:40:53 | FromDiscord | <Elegant Beef> (edit) 'winne' => 'winner' |
| 00:41:03 | FromDiscord | <Elegant Beef> The point is im automating the creation of packets |
| 00:41:13 | FromDiscord | <Elegant Beef> So i just need to read primitive types off the packets |
| 00:42:14 | FromDiscord | <Elegant Beef> A person can add a pragma, it then generates a packet ID, to/from methods and adds a send packet if not reading from a buffer |

| 00:44:31 | FromDiscord | <Elegant Beef> Or not |
| 00:44:40 | FromDiscord | <Elegant Beef> Cause it also uses the address |
| 00:44:54 | FromDiscord | <Elegant Beef> Ok this is out of the scope of my knowledge |

| 01:18:53 | FromDiscord | <Zachary Carter> I think I figured out the problem with my importcpp objects and the destructors not being called consistently |
| 01:19:38 | FromDiscord | <Zachary Carter> I think it's because the code I'm writing is being compiled to a shared library and loaded with dlopen / close |
| 01:21:46 | FromDiscord | <Zachary Carter> and the variable that is of the type with the fields that are importcpp'd is a static global |
| 01:23:53 | FromDiscord | <Zachary Carter> so the destructors aren't guaranteed to be called when the library is unloaded |
| 01:25:20 | FromDiscord | <Zachary Carter> so I guess I have a few options - create equivalent Nim types and use copyMem and only instantiate the C++ objects inside of procs |
| 01:25:30 | FromDiscord | <Zachary Carter> or write a C99 API for this C++ API and bind to that :/ |
| 01:25:37 | FromDiscord | <Zachary Carter> both options sound like a lot of work... |
| 01:29:04 | FromDiscord | <Zachary Carter> I wish there was an easy way to generate a C99 API for a C++ library automatically - BGFX did some idl magic but it looks like a lot of work in of itself |

| 01:43:41 | FromDiscord | <Zachary Carter> well - I'm successfully using plugins but with a C library |
| 01:44:12 | shashlick | It works fine with boehm but not arc |
| 01:44:50 | FromDiscord | <Zachary Carter> yeah boehm is a no-go for me |

| 01:44:57 | * | tinga quit (Ping timeout: 260 seconds) |
| 01:45:22 | FromDiscord | <Zachary Carter> but I don't think the GC has much to do with my issue here |
| 01:45:32 | FromDiscord | <Zachary Carter> you'd encounter the same issue if you were writing shared libraries with C++ |
| 01:45:57 | FromDiscord | <Zachary Carter> I think anyway... |
| 01:46:36 | leorize | why are you dlclose()-ing? |
| 01:46:53 | FromDiscord | <Zachary Carter> I'm not - the C library is |
| 01:46:54 | leorize | is that a plugin system kind of thing? |
| 01:46:57 | FromDiscord | <Zachary Carter> yes |
| 01:47:42 | FromDiscord | <Zachary Carter> my code is being loaded as a plugin by the executable that's written in C |
| 01:47:52 | FromDiscord | <Zachary Carter> and then when the process terminates it is calling dlclose on it |
| 01:48:14 | leorize | and your problem is? |
| 01:48:42 | FromDiscord | <Zachary Carter> so I have a C++ library I've constructed a wrapper for |
| 01:49:15 | FromDiscord | <Zachary Carter> in my Nim code that's being compiled to a shared library, I have a type defined which has several fields which are of types defined in this wrapper |
| 01:49:36 | FromDiscord | <Zachary Carter> I then have a global variable in the shared library of this Nim object type |
| 01:50:14 | FromDiscord | <Zachary Carter> the destructors for the importcpp'd fields in this object aren't getting called always |
| 01:50:50 | FromDiscord | <Zachary Carter> so I can't call them explicitly and I can't rely on them being called implicitly |
| 01:51:25 | FromDiscord | <Zachary Carter> but apparently this is a known issue with some C++ compilers - https://stackoverflow.com/questions/38510621/destructor-of-a-global-static-variable-in-a-shared-library-is-not-called-on-dlcl |
| 01:53:47 | leorize | I think the main problem is that you just can't register anything to be called when the library is closed |
| 01:53:49 | FromDiscord | <Elegant Beef> @Rika well this works, and it looks hideous, but now it writes the byte to a string stream↵https://play.nim-lang.org/#ix=2rmU |
| 01:54:02 | leorize | also keep in mind that dlclose() is permitted to **not** close |
| 01:54:04 | FromDiscord | <Elegant Beef> Obviously strings will cause it to implode |
| 01:54:06 | leorize | per POSIX |
| 01:54:40 | FromDiscord | <Elegant Beef> Also i swear i tested write previously and it wasnt proper |
| 01:54:46 | FromDiscord | <Elegant Beef> But now it seems to wrok |
| 01:54:49 | FromDiscord | <Elegant Beef> (edit) 'wrok' => 'work' |
| 01:54:53 | FromDiscord | <Zachary Carter> yeah - I think I just need to bite the bullet and write a C99 API for this library |
| 01:55:13 | FromDiscord | <Zachary Carter> if I really want to continue working on this project and not just start using Unity / some C++ engine on github |
| 01:55:16 | leorize | why can't you just call the destructor manually? |
| 01:55:24 | FromDiscord | <Zachary Carter> because it might be double freed |
| 01:55:37 | leorize | actually, why are you using something that requires to be destroyed? |
| 01:56:07 | FromDiscord | <Zachary Carter> because there's a leak detector in the library I'm using which asserts that no allocations have occurred that haven't been deallocated |
| 01:56:16 | FromDiscord | <Zachary Carter> I can probably just fork the library and get rid of that |
| 01:56:34 | * | maier joined #nim |
| 01:56:54 | leorize | they might have a way to mark something as still in use so it wouldn't trip |
| 01:57:03 | FromDiscord | <Zachary Carter> maybe... |
| 01:58:26 | leorize | can you just call the destructor explicitly then memset the area to 0 to prevent any double free? |
| 01:58:52 | leorize | unless you don't know the real object size... then that's a problem... |
| 01:59:07 | leorize | or you can turn the object into a heap object, then you can just delete the pointer when you're done |

| 07:43:48 | FromDiscord | <Varriount> Araq: Why do streams in the streams module use a null byte as an EOF indicator? What if the stream naturally contains a null byte? |
| 07:45:28 | FromDiscord | <Elegant Beef> i hope the answer is "Just dont do that" 😄 |
| 07:46:41 | FromDiscord | <Varriount> If it is, then that's a serious concern. Files, IP, and data streams in general are usually allowed to carry null bytes. |
| 07:50:44 | FromDiscord | <Elegant Beef> String stream doesnt |

| 08:14:44 | FromDiscord | <Varriount> Though, the reopening in my state doesn't seem to have helped. |

| 15:12:39 | FromDiscord | <treeform> Hey so iterating over enums used to work? How to get it back? I have an enum with holes, and I want all of the enum names in a for loop. |
| 15:14:00 | solitudesf | it used to work wrong, since it would yield incorrect values |
| 15:15:44 | FromDiscord | <Clyybber> I had a fix, but it required macros.nim, so I can't put it in system.nim |
| 15:16:03 | FromDiscord | <treeform> https://play.nim-lang.org/#ix=2rox |
| 15:16:11 | FromDiscord | <treeform> what should I do now? How to work around? |
| 15:16:29 | FromDiscord | <Clyybber> write an items iterator that just runs over the full set |
| 15:16:45 | FromDiscord | <Clyybber> make a macro to construct the full set expression from a enum type |
| 15:17:00 | FromDiscord | <treeform> I am not using sets? |
| 15:17:08 | disruptek | you will be. |
| 15:17:40 | mbuchel | is there an easy way to make a union of 2 or more datatypes without using macros? |
| 15:19:13 | FromDiscord | <treeform> Can I do some thing like `for button in 0 .. Button.high:`? Does not looks like high works for enums... |
| 15:20:05 | FromGitter | <memnoth> A newb's question. Is there a reason that dollar opt on array written like this? As a consequence, it returns whole values with [, comma, and ] though. --> https://github.com/nim-lang/Nim/blob/21772b6419b6cb3b59b436fbdcd8975a9da62349/lib/system/dollars.nim#L166 |
| 15:20:31 | FromDiscord | <Yardanico> @memnoth well yes, $ is supposed to return a human-readable representation of something |
| 15:21:50 | FromDiscord | <treeform> Looks like this works: `for button in 0 .. ord(high(Button)): echo Button(button)` I guess I'll be using that. |
| 15:22:17 | FromDiscord | <treeform> I liked the previous method better. |
| 15:22:20 | FromDiscord | <treeform> Much cleaner |
| 15:28:00 | FromGitter | <memnoth> @Yardanico that means the opt represents it as you said rather than stringify it? |
| 15:28:17 | FromDiscord | <Yardanico> ? |
| 15:28:31 | FromDiscord | <Yardanico> $ operator usually means "return a human-readable representation of something" |
| 15:28:33 | FromDiscord | <Yardanico> in nim |
| 15:28:57 | FromDiscord | <Yardanico> it's not about making a machine-parsable or something (for that there's JSON and friends) |
| 15:37:12 | FromDiscord | <Clyybber> @treeform You want to iterate over all valid enum states right? |
| 15:38:33 | FromDiscord | <Clyybber> This is what I would do: https://play.nim-lang.org/#ix=2roE |
| 15:38:49 | FromDiscord | <Clyybber> And to generate this "whole set" automatically I would use a macro |
| 15:39:44 | FromGitter | <memnoth> What should I do from an array of cchar to string? the $ opt doesn't work as I expected, for instance, it returns like "['s', 'r', 'c', '\x00']" with "echo $path". Or do I have to make a new toString proc? |
| 15:40:19 | FromDiscord | <treeform> @Clyybber I see, thanks. |
| 15:40:24 | FromGitter | <memnoth> Nim tutorial says $ opt is usually used to toString though. |
| 15:41:01 | FromDiscord | <Clyybber> memnoth: Is the array nullterminated? |
| 15:41:12 | FromGitter | <memnoth> @Clyybber Yes |
| 15:41:48 | FromDiscord | <Clyybber> Do this then: cast[string](@thearray) |
| 15:43:42 | FromDiscord | <Clyybber> @flywind You can probably use testaments errormsg: param, I think the error was that you included the full path |
| 15:47:07 | FromGitter | <memnoth> @Clyybber thank you for that. it works. |

| 15:58:36 | leorize | @Clyybber that's pretty unsafe |
| 15:58:51 | leorize | this should be safer: `$cast[cstring](theArray[0])` |

| 16:29:28 | shashlick | @Clyybber - see https://github.com/genotrance/plugins/blob/master/src/plugins/globals.nim#L18 - Plugins point to PluginManager which points to Plugins |
| 16:30:22 | FromDiscord | <Yardanico> well even with arc applications with cycles shouldn't crash |
| 16:30:38 | FromDiscord | <Yardanico> they will just leak some memory 😛 |
| 16:31:48 | FromDiscord | <Clyybber> shashlick: Alright, now where should I put all the arc switches? |
| 16:32:06 | shashlick | note also that plugin dlls call procs in the main executable - https://github.com/genotrance/plugins/blob/master/src/plugins/utils.nim#L418 so i've seen some memory issues with that |
| 16:32:12 | shashlick | all this works with boehm |
| 16:32:43 | shashlick | to avoid that issue, simply comment out the line in config.nims, change plugin.nim call to nim c and add the flag there |
| 16:33:01 | shashlick | and then compile main executable with `nim c --gc:arc -r tests/tmain` |
| 16:33:15 | shashlick | that way, main exe and dlls are compiled with the same switches |
| 16:33:19 | FromDiscord | <Yardanico> won't you need e.g. to use GC_ref GC_unref when using dll plugins? |
| 16:33:25 | FromDiscord | <Yardanico> for GC'd memory |
| 16:33:52 | FromDiscord | <Clyybber> shashlick: I don't have that issue with config.nims |
| 16:33:53 | shashlick | also make sure you delete the compiled dlls in tests/test1 |
| 16:34:14 | shashlick | okay then that one change in config.nims should be good enough |
| 16:34:21 | FromDiscord | <treeform> @Vindaar, thanks! |
| 16:34:23 | FromDiscord | <Clyybber> ok |
| 16:34:59 | FromDiscord | <Yardanico> but really a generic solution for splitting nim applications into different libraries (to be used from other nim libraries/applications) would be awesome |
| 16:35:09 | shashlick | that's what plugins package aims to be |
| 16:35:14 | FromDiscord | <Clyybber> so what do I need to do to run the tests? Before I simply did nim r --gc:arc tests/tmain |
| 16:35:21 | FromDiscord | <Clyybber> Do I need to compile some plugins too? |
| 16:35:27 | shashlick | that should be good enough - the main exe compiles the plugins |
| 16:35:42 | shashlick | but just make sure you delete them before tests else it will use the existing files |
| 16:35:48 | shashlick | in case you change flags |
| 16:35:48 | FromDiscord | <Clyybber> ugh |
| 16:36:02 | shashlick | the nimble test does all this but doesn't print anything |
| 16:36:04 | FromDiscord | <Clyybber> ok, *now* i'm getting the config.nims error you spoke of |
| 16:37:16 | FromDiscord | <Clyybber> what must I do to make tmain work? |
| 16:38:57 | FromDiscord | <Clyybber> shashlick: ping |
| 16:42:39 | FromDiscord | <Clyybber> why is it compiling stuff at runtime? |
| 16:48:04 | FromDiscord | <Clyybber> Ok, I compiled them manually now with the --gc:arc switch |
| 16:48:10 | FromDiscord | <Clyybber> fails with both my PR and on devel |
| 16:49:26 | shashlick | I tried with useMalloc and it went a bit further |
| 16:49:38 | shashlick | Looking at gdb output might give you some ideas |
| 16:49:53 | shashlick | Fails mainly in memory alloc dealloc |
| 16:50:29 | shashlick | That's the point of plugins - it compiles them automatically when they change and reload |
| 16:51:22 | FromDiscord | <Clyybber> does it use the compiler api to do that? Or does it call the compiler via execCmd? |
| 16:52:09 | FromDiscord | <Clyybber> because if its the former its kinda expected to not work yet |
| 17:02:48 | shashlick | It calls Nim binary not api |
| 17:03:04 | shashlick | execCmd |
| 17:03:37 | shashlick | Plugins get compiled in background thread on change |
| 17:03:44 | shashlick | Main thread loads dlls |
| 17:04:04 | shashlick | Reloads when background thread tells it to |
| 17:06:17 | shashlick | This is all just standard threads and dynlib but the problem is in using memory across dlls, not even threads anymore now that I replaced that interaction with channels |
| 17:06:53 | shashlick | Should the dlls be compiled with gc none? Does arc know how to sync across dlls |
| 17:10:04 | FromDiscord | <Clyybber> arc doesn't do anything special, so it should probably work |
| 17:21:26 | FromDiscord | <demotomohiro> Why std/with or std/compilesettings modules are not listed here?↵https://github.com/nim-lang/Nim/blob/devel/doc/lib.rst |

| 20:27:57 | FromDiscord | <Yardanico> @dadada yes, as Rika said |
| 20:27:58 | FromDiscord | <Recruit_main707> ... becuase id rather not needing to mark every method with a pragma |
| 20:28:05 | FromDiscord | <Yardanico> you can also install from github directly even if the library isn't on nimble |
| 20:28:09 | FromDiscord | <Yardanico> if it has a .nimble file of course |
| 20:28:23 | dadada | Rika, Yardanico, neat! |

| 20:37:21 | FromDiscord | <Elegant Beef> So... Rust's UFCS eh? 😄 |
| 20:37:30 | FromDiscord | <lqdev> since when |
| 20:37:49 | FromDiscord | <Elegant Beef> Im joking, i just spent a while arguining why their Universals FCS isnt UFCS 😄 |
| 20:37:57 | FromDiscord | <Elegant Beef> with a friend * |
| 20:38:05 | * | Shucks joined #nim |
| 20:38:06 | FromDiscord | <lqdev> universal FCS? |
| 20:38:17 | FromDiscord | <Elegant Beef> Yea they call it universal function calling syntax |
| 20:38:20 | FromDiscord | <lqdev> what are they referring to? |
| 20:38:36 | FromDiscord | <Elegant Beef> https://doc.rust-lang.org/1.7.0/book/ufcs.html |
| 20:38:37 | FromDiscord | <Elegant Beef> This |
| 20:38:42 | FromDiscord | <Elegant Beef> Traits behaving like UFCS |
| 20:39:13 | FromDiscord | <lqdev> dear lord |
| 20:39:27 | FromDiscord | <lqdev> yet another feature to add to the list of confusing features of rust |
| 20:39:31 | FromDiscord | <Elegant Beef> He ended up telling me to use rust and just use traits only |
| 20:39:44 | FromDiscord | <lqdev> ah, like a true rust evangelist. |
| 20:39:49 | FromDiscord | <Elegant Beef> I may or may not have repeated "It's not uniform" many times |
| 20:40:06 | FromDiscord | <lqdev> well it stands for "unified" iirc |
| 20:40:15 | FromDiscord | <Elegant Beef> It's uniform |
| 20:40:24 | FromDiscord | <Elegant Beef> https://en.wikipedia.org/wiki/Uniform_Function_Call_Syntax |
| 20:40:27 | FromDiscord | <lqdev> but nim calls it method call syntax which is less confusing. |
| 20:40:34 | FromDiscord | <lqdev> ok good to know |
| 20:40:59 | dadada | Rika: some awesome features are underdocumented! @Yardanico |
| 20:41:07 | FromDiscord | <Yardanico> which ones? 😛 |
| 20:41:23 | FromDiscord | <Rika> ? |
| 20:41:24 | FromDiscord | <Yardanico> this one is documented |
| 20:41:27 | FromDiscord | <Yardanico> https://github.com/nim-lang/nimble#nimble-install |
| 20:41:27 | FromDiscord | <Rika> yes |
| 20:41:51 | * | Vladar quit (Quit: Leaving) |
| 20:42:51 | dadada | Yardanico: using project@#head .... those project pages on nimble.org should maybe display this alternative along with moe install project ... I know I would have seen it there, because that's where I looked first |
| 20:44:04 | dadada | Rika: I didn't mean that it is completely undocumented, but the usage examples belong where the users go to look for applications, not buried inside the nimble documentation a new user will almost never care to read |
| 20:45:18 | dadada | today we have cargo, nimble, pip, dnf, apt-get, npm, this growing list of package managers, and I can't keep up with all their features |
| 20:45:48 | dadada | but what I can do is read a project homepage/README and their install sections IMO should include how to install the latest dev version with nimble |
| 20:45:55 | FromDiscord | <Elegant Beef> You have nimble, just remove cargo,pip,npm 😄 |
| 20:45:55 | dadada | especially nimble.org should have this |
| 20:46:04 | FromDiscord | <Rika> beef LMAO |
| 20:46:27 | FromDiscord | <Elegant Beef> What'd i say that wasnt the truth? |
| 20:46:32 | dadada | Elegant Beef: I'd love to, especially npm ... |
| 20:46:43 | FromDiscord | <Elegant Beef> Also rika i have all primitive types serializing, pointer objects do not |
| 20:46:53 | FromDiscord | <Skippy> I wonder, do people who's mother tongue is not english do you code in english? |
| 20:47:48 | Prestige | What is the locklevel warning about? |
| 20:48:11 | FromDiscord | <Elegant Beef> I mean considering all the keywords are in english partly |
| 20:48:14 | FromDiscord | <Rika> beef: I figured, pointer objects are more complex |
| 20:48:17 | FromDiscord | <Elegant Beef> Yea |
| 20:48:35 | FromDiscord | <Elegant Beef> It's a pain but i can save/load all primitives, and i didnt need to write any code |
| 20:48:38 | FromDiscord | <Elegant Beef> So objects partly reload |
| 20:48:49 | FromDiscord | <Clyybber> @Skippy yeah |
| 20:49:08 | planetis[m] | clyybber, I replied to the issue, it's fixed! |
| 20:50:02 | Prestige | Specifically: Warning: method has lock level <unknown>, but another method has 0 |
| 20:50:09 | FromDiscord | <Rika> grim consumes so much memory for 200k nodes :Pensiveaf: |
| 20:52:03 | FromDiscord | <Elegant Beef> https://play.nim-lang.org/#ix=2rpK↵How would we call the concept using foo? |
| 20:53:22 | FromDiscord | <Rika> " |
| 20:53:23 | FromDiscord | <Rika> ? |
| 20:53:41 | FromDiscord | <Elegant Beef> Well it calls the type speciffffic implementation |
| 20:53:47 | FromDiscord | <treeform> @Technisha In my ws library I don't expose the connections ... maybe I should... but you can just have your own list and send to it ... see my chat server example: https://github.com/treeform/ws/blob/master/tests/chat.nim |
| 20:53:57 | FromDiscord | <Elegant Beef> (edit) 'speciffffic implementation' => 'specific implementation,' |
| 20:54:08 | FromDiscord | <Elegant Beef> Im curious how you'd call the concept implementation if there is overlap |
| 20:54:19 | FromDiscord | <treeform> @Technisha Circuit (LGBTQIAP+) ^ |
| 20:54:21 | FromDiscord | <Rika> @Elegant Beef it resolves to the most specific definition, and since foo(Baz) is the most specific, it uses that |
| 20:54:26 | FromDiscord | <Elegant Beef> Yea i know that |
| 20:54:43 | FromDiscord | <Elegant Beef> Im curious if there is a way to specifically call the concept one |
| 20:54:58 | FromDiscord | <Elegant Beef> I know this is a rather unlikely situation, just curious |
| 20:55:29 | * | tane quit (Quit: Leaving) |
| 20:55:53 | FromDiscord | <Rika> honestly dunno |
| 20:56:26 | FromDiscord | <Technisha Circuit (LGBTQIAP+)> > @Technisha In my ws library I don't expose the connections ... maybe I should... but you can just have your own list and send to it ... see my chat server example: https://github.com/treeform/ws/blob/master/tests/chat.nim↵Thanks! |
| 20:57:11 | FromDiscord | <Elegant Beef> So if you use `foo(c = Baz())` that works, but now if they're both the same parameter you're kinda pooched |
| 20:57:36 | * | madprops left #nim ("Leaving") |
| 20:58:09 | shashlick | I'll strongly discourage using project@#head for any project |
| 20:58:14 | shashlick | Using nimble |
| 20:58:42 | shashlick | Cause once it's installed, nimble will always pick it even if newer specific versions are installed |
| 20:58:57 | shashlick | You could have a year old head sitting there throwing off all requirements |
| 20:58:58 | FromDiscord | <lqdev> using #head is generally bad |
| 20:59:09 | FromDiscord | <lqdev> because like, stability |
| 20:59:16 | FromDiscord | <lqdev> and it screws up versioning |
| 20:59:23 | FromDiscord | <lqdev> never use a #head version in your .nimble file |
| 20:59:29 | planetis[m] | clyybber, what do you think now? is it fixed or should I keep trying making examples? |
| 20:59:32 | * | laqq3 joined #nim |
| 20:59:55 | shashlick | Goes back to disruptek suggestion to install vx.x.x when requires >= vx.x.x instead of latest version |
| 21:00:30 | shashlick | Should use the minimum version suggested by the nimble file |
| 21:00:42 | shashlick | That way things are reproducible |
| 21:01:00 | shashlick | But will break many packages if nimble is to change |
| 21:04:34 | FromDiscord | <exelotl> on the topic of npm being garbage, has anyone used pnpm? |
| 21:05:03 | FromDiscord | <exelotl> it's like a droplet of sanity in a sea of foolishness |
| 21:08:03 | FromDiscord | <Clyybber> planetis[m]: I tested both the initial scoped commit and before that and devel |
| 21:08:18 | FromDiscord | <Clyybber> Theres no leak with any of them with the original example |
| 21:08:42 | FromDiscord | <Clyybber> Did you determine that there are leaks by looming at the C code? |
| 21:09:24 | planetis[m] | no I have a program that ooms and when I remove the parentesis it is fixed |
| 21:09:33 | FromDiscord | <Clyybber> huh ok |
| 21:09:49 | planetis[m] | https://github.com/b3liever/neuralnet-examples/blob/master/minibatches.nim |
| 21:09:53 | FromDiscord | <Clyybber> I'm not at my PC rn |
| 21:09:59 | FromDiscord | <Clyybber> but I'll look into it asap |
| 21:10:38 | planetis[m] | relax, I just don't use this syntax anymore |
| 21:10:53 | planetis[m] | it's easy to workaround |
| 21:11:48 | planetis[m] | the c code I posted doesn't look weird to you? |
| 21:12:46 | planetis[m] | it copies twice the seq elements and then only uses one field from each tuple |
| 21:14:05 | FromDiscord | <Elegant Beef> Is it impossible to call the `foo(b: C)` with this setup? I cannot think of a method when the signatures are identical minus the type↵https://play.nim-lang.org/#ix=2rpM |

| 21:18:53 | Shucks | How well does clang do with nim? |
| 21:20:13 | planetis[m] | I am so exhausted from the week i was actually sleeping all day lol |
| 21:26:51 | FromDiscord | <Yardanico> @Shucks just fine |
| 21:26:58 | FromDiscord | <Yardanico> but performance might differ for different programs 🙂 |
| 21:27:10 | FromDiscord | <Yardanico> sometimes clang-compiled binaries are slower, sometimes on par with gcc, sometimes a little faster |
| 21:27:18 | FromDiscord | <Yardanico> but you shouldn't have any problems with using it anyway |
| 21:28:50 | FromDiscord | <Yardanico> by slower or faster I mean <10% usually |
| 21:29:47 | Shucks | alright. I guess theres no straight answer which compiler produces the smallest/fastest binaries with nim huh? Since gcc/mingw is recommend on the website I guess I'll just stick with it |
| 21:31:06 | Shucks | and 10% is pretty much imo ;D |

| 21:57:30 | FromDiscord | <Varriount> @Elegant Beef Possibly if you write `C.foo(variable)`? Other than that possibility, I can't think of any other way |

| 22:08:13 | FromDiscord | <Elegant Beef> Seems like the only way to differentiate is module splitting |
| 22:17:11 | FromDiscord | <Elegant Beef> Can nim not change the identifier of a proc on import? |
| 22:17:44 | FromDiscord | <Elegant Beef> `from fooconc import foo as fooConcept` |

| 23:08:45 | FromDiscord | <Yardanico> @Shucks well I meant that clang can be sometimes even 10% or more slower with Nim, or 10% or more faster |
| 23:09:03 | FromDiscord | <Yardanico> And yes, there's no reason not to use LTO with most Nim programs when you make a release build |
| 23:09:12 | FromDiscord | <Yardanico> It's just free performance gains (in most cases) |

| 23:17:10 | FromDiscord | <Rika> in what cases are they not? |
| 23:19:56 | FromGitter | <deech> Does the stdlib have a function that converts between C++ `bool` and Nim `bool`? |
| 23:23:43 | FromDiscord | <Varriount> deech: `bool(cboolvariable)`? |
| 23:23:51 | FromDiscord | <Varriount> Oh, C++ |
| 23:24:03 | FromDiscord | <Varriount> Isn't a C++ bool the same as a C bool? |
| 23:24:20 | FromDiscord | <Varriount> It's just a byte (implementation-wise, if not standards-wise) |
| 23:26:09 | FromGitter | <deech> Oh nice. I didn't know I could just convert like that. |
