| 07:10:10 | FromGitter | <Varriount> @BigEpsilon Does this mean C2Nim will be able to parse anonymous structs? |
| 07:16:30 | Araq | mahmudov: never seen this. is /usr/lib in your LD_PATH or whatever it's called |
| 07:16:31 | PMunch | mahmudov, do you have SDL installed? |
| 07:16:50 | PMunch | Oh wait, you said that you do have it |
| 07:16:53 | mahmudov | yes already i showed it |
| 07:17:03 | Araq | 64 vs 32 bit problem? |
| 07:17:30 | mahmudov | ofc my usr/lib in LD_PATH |
| 07:18:07 | PMunch | Yeah, my libSDL2.so is in /usr/lib64 |
| 07:18:20 | PMunch | So it could be a 32 vs. 64 issue |
| 07:19:18 | mahmudov | but i use pure 64 |
| 07:20:04 | PMunch | Try "objdump -f /usr/lib/libSDL2.so" |
| 07:20:08 | mahmudov | hm it looks under /usr/lib64 |

| 07:24:15 | mahmudov | how can we do search /usr/lib also ? |

| 07:32:19 | mahmudov | ok |
| 07:34:50 | Araq | mahmudov: the search is generally not really under Nim's control |
| 07:35:16 | mahmudov | so ? |
| 07:35:30 | mahmudov | it looks by sdl2 code ? |
| 07:35:35 | mahmudov | or sense |
| 07:35:40 | Araq | so it's an OS issue :P |
| 07:36:14 | Araq | probably good for security, nothing is more secure than refusing to run code altogether |

| 07:37:26 | PMunch | Well, it's probably not a good idea to run a 32-bit binary on a 64 bit system :P |
| 07:37:47 | PMunch | mahmudov, maybe symlink your entire /usr/lib64 to /usr/lib then? |
| 07:37:47 | mahmudov | ofc. |
| 07:37:57 | mahmudov | but some linux distros run together |
| 07:38:35 | mahmudov | but i know a program,code looks under ld_path |
| 07:38:48 | mahmudov | it can be /usr/lib /usr/lib6 |
| 07:38:52 | mahmudov | or etc |
| 07:39:08 | mahmudov | you know i can add a path under /etc/ld.so.conf |
| 07:39:12 | mahmudov | in linux |
| 07:39:29 | mahmudov | to look libraries from apps |
| 07:39:42 | Araq | you can also use some linker hacks (there was a PR to do that), *shrug* |

| 07:47:28 | mahmudov | how it defines *.so in linux, |

| 07:48:09 | Araq | you said it yourself, const LibName* = "libSDL2.so" ? |
| 07:48:26 | mahmudov | ok sdl2.nim does it |
| 07:48:38 | mahmudov | so then? |
| 07:48:46 | mahmudov | how find the *.so |
| 07:49:38 | Araq | mahmudov: have a look at https://github.com/nim-lang/Nim/pull/6145 |
| 07:50:12 | mahmudov | lemme |
| 07:50:31 | Araq | it uses dlopen to find the *.so, if dlopen looks at /usr/lib and not at /usr/lib64 or vice versa it's broken. |
| 07:50:54 | Araq | there is only so much we can do about fixing your OS for you. |
| 07:51:56 | mahmudov | wait i mean it doesnt look LD_PATH ? |

| 09:23:18 | FromGitter | <mratsim> @mahmudov I think this is more for your distro IRC than Nim's, if your distro doesn't set the LDPATH or the /etc/ld.conf.d/ or /etc/ld.conf we can't do anything about it, even compiling a C program with a shared lib dependency (say libjpeg) will fail |
| 09:27:55 | FromGitter | <mratsim> Furthermore I didn't understand a single thing on their website but apparently it's based on Linux from scratch so you probably have to do a lot of configuration yourself. If your distro is not up to par in documentation I suggest you have a look in Archlinux doc or Gentoo docs regarding linker and LDPATH those 2 distros have the best docs for DIY Linux |

| 12:19:18 | FromGitter | <edubart> In manual, the `||` operator used for OpenMP has this body: `iterator `||`S, T (a: S; b: T; annotation = ""): T {..}` how to I pass the annotation argument in a for loop? I've tried `for i in 0||size,"myannotation"` without success |
| 12:28:07 | FromGitter | <Yardanico> no, you would call it another way |
| 12:28:34 | FromGitter | <Yardanico> ```for x in `||`(0, size, "hi")``` ⏎ ⏎ something like this [https://gitter.im/nim-lang/Nim?at=59ca47f1b20c6424298ab4d8] |

| 13:09:10 | couven92 | Araq, if I implement a flag type for importc as a `distinct int32`, is there a way I can implement set literal syntax for initialization? Like: In the nim code it looks like a regular set, but in reality it is a `distinct int` with all the set procs implemented to make it look like a set? |
| 13:12:39 | FromGitter | <couven92> or is the following completely impossible? ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=59ca5247cfeed2eb655073d6] |
| 13:14:09 | couven92 | I know implementing `in`, `notin`, etc is no problem... but initialization? |
| 13:16:12 | Araq | don't use {} for this |
| 13:16:59 | couven92 | Araq, instead `proc NewMyFlags(values: varargs[MyFlag]): MyFlag`? |

| 15:40:04 | FromGitter | <Yardanico> Trojan horse reported by avira free-av during the setup (installer) |
| 15:41:35 | Araq | couven92: system.NimVersion exists |
| 15:41:44 | couven92 | ah! :) |
| 15:42:36 | FromGitter | <genotrance> any opinion on Mingw-w64 vs VS20xx on Windows as the compiler backend for Nim? Also Clang? |
| 15:43:54 | couven92 | @genotrance the vccexe tool greatly simplifies using the vcc compiler backend (not yet ready for VS2017, but I'm working on it) |
| 15:45:13 | couven92 | @genotrance MinGW is a MUCH smaller install, but if you already have VS20xx installed, you get native cross-compilation out of the box |

| 15:46:21 | FromGitter | <genotrance> i already have mingw working so not much incentive to fight with VS |
| 15:46:33 | FromGitter | <genotrance> but just curious if it is worth it to move to express |
| 15:46:52 | FromGitter | <genotrance> also, was looking at Clang but that needs VS as well so am not very motivated |
| 15:48:21 | couven92 | and as soon as https://github.com/nim-lang/Nim/pull/6397 gets merged (Araq?) nim will also generate Visual Studio (and VS Code) step-by-step debugging information |
| 15:48:36 | FromGitter | <Varriount> It's possible to install just the Visual C compiler without Visual Studio |
| 15:48:39 | couven92 | although I think GDB works fine on windows with MinGW as well, right? |
| 15:49:29 | couven92 | @genotrance yes, as @Varriount points out, here's the standalone build tools link: http://landinghub.visualstudio.com/visual-cpp-build-tools |
| 15:49:44 | FromGitter | <genotrance> ya gdb works well for the most part |
| 15:49:57 | FromGitter | <Varriount> Microsoft finally re-added the package, after removing it for a couple of years |
| 15:50:35 | couven92 | @genotrance do GDB and VS code play nice with each other? |
| 15:50:57 | couven92 | i.e. do you get setp-by-step debugging with GDB on Windows in VS code? |
| 15:51:58 | FromGitter | <genotrance> no idea, I just use Scite for an editor, gdb on the command line and build with mingw |
| 15:52:14 | * | mahmudov left #nim ("Leaving") |
| 15:52:26 | FromGitter | <genotrance> so as low-tech as it gets for now |
| 15:52:42 | FromGitter | <Varriount> Attach to the process? |
| 15:53:23 | couven92 | ah... would be interesting to know how that works... The reason why I use VS daily is because I mostly write C# and I am spoiled by rich IntelliSense and step-by-step debugging |
| 15:53:55 | FromGitter | <genotrance> I'd like to be spoiled for a change, sounds like I should install vscode and vs build tools and see how it works out |
| 15:54:05 | FromGitter | <genotrance> can you do step by step debugging with vs code for Nim? |

| 18:23:04 | adeohluwa | genotrace: https://www.quora.com/What-do-you-say-about-Nim-programmning-language |
| 18:23:15 | FromGitter | <krux02> I don't have problems with the compiler error messages, I like that the order of procedure declarations still matters, style insesitiveness is something I just pretent is not there, and the last poist, yea, just ignorant |
| 18:23:29 | FromGitter | <krux02> where is that from? |
| 18:23:29 | adeohluwa | TjYoco: like I said 3 & 4 are subjective |
| 18:23:57 | adeohluwa | quora |
| 18:24:55 | adeohluwa | libman: I'm thinking along the lines of hand holding errors |
| 18:25:14 | * | claudiuinberlin quit (Quit: My MacBook has gone to sleep. ZZZzzz…) |
| 18:25:17 | TjYoco | well, adeohluwa, its still in development so it will only get better from here |
| 18:25:20 | adeohluwa | I think elm language & racket language set the bar high for error messages |
| 18:25:39 | adeohluwa | TjYoco: I'm not super worried already hooked to nim lang |
| 18:25:51 | FromGitter | <krux02> scala, too |
| 18:25:57 | adeohluwa | its sort of already the best thing out there to me so I'm hostage |
| 18:26:21 | FromGitter | <krux02> scala is a very nice language, where I never had out of index errors or null pointer stuff |
| 18:26:45 | Araq | (1) is mostly ignorance, a powerful language which metaprograms its features will always have worse error messages. it's a tradeoff |
| 18:27:05 | adeohluwa | krux02: never looked into it |
| 18:27:10 | Araq | (2) will be addressed by the reorder PR |
| 18:27:57 | FromGitter | <krux02> Araq: not sure about (1), I think Nim allows custom error messages for embedded DSLs, that is far superior to what most c++ metaprogramming is |
| 18:28:04 | adeohluwa | Araq: kinda like lisps , #2 is good news tho! |
| 18:28:56 | Araq | (3) is irrelevant. could enforce a style in the compiler instead, this would forbid under_scores, but designer fascism is not "engineering" |
| 18:29:12 | FromGitter | <krux02> most important to me is that error messages are actually reported, where the error occurs, I just remember c++ errors in files where no error was. I just forgot a semicolon at the end of a header |
| 18:29:20 | FromGitter | <krux02> but it got better by now |
| 18:29:32 | adeohluwa | hilarious! |
| 18:29:33 | FromGitter | <krux02> maybe we should stop arguing about this no |
| 18:29:37 | libman | The ideal programming language would express errors by playing videos of nude college girls dancing while reciting the error details. |
| 18:29:51 | ivmachiavelli | lol |
| 18:30:03 | FromGitter | <krux02> well yea |
| 18:30:07 | * | claudiuinberlin joined #nim |
| 18:30:17 | Araq | (4) can be done with a tuple of closures, a bit verbose but it works |
| 18:30:22 | FromGitter | <krux02> I guess that would take the focus away |
| 18:30:33 | Araq | and is used extensively in the compiler too. |
| 18:30:45 | adeohluwa | libman: true I just stumbled on the page while answering a Nim question thought it was roughly accurate versus mostly biased views u see around |
| 18:30:52 | libman | (With gender and other preference settings, of course.) |
| 18:31:24 | TjYoco | coming from c# and not being a programmer by trade, #4 is very hard for me to get used to |
| 18:32:53 | FromGitter | <krux02> but you dont need mixins in nim |
| 18:33:09 | FromGitter | <krux02> it's just a different style of programming |
| 18:33:30 | FromGitter | <krux02> I used taits in scala and implicit conversions and stuff to extent my classes |
| 18:33:51 | FromGitter | <krux02> and then I learned about Nim, and all of a sudden I just stopped needing that stuff |
| 18:34:01 | FromGitter | <krux02> I could do everything with simple procs |
| 18:34:12 | FromGitter | <krux02> really felt like a relieve not a constraint |
| 18:34:20 | FromGitter | <krux02> and then I can place them whereever I want to |

| 19:04:52 | FromGitter | <Yardanico> at least dom96 did it :DDD |
| 19:05:40 | ivmachiavelli | Just wondering where everyone picked up the language other than the docs I don't really see many resources yet. |
| 19:06:04 | ivmachiavelli | I just started the book |
| 19:07:17 | FromGitter | <genotrance> @ivmachiavelli: I used the docs to port my Python app to Nim - it was pretty much line by line minor syntax changes. Helped get an understanding of stuff. After that, it was references here and there when I was trying to accomplish specific things |
| 19:10:23 | FromGitter | <Jipok> @genotrance >do we have a page describing how to best use VSCode with Nim - dev, debug, etc? ⏎ Unfortunately no. And not just for vscode, but in general. ⏎ Although if for vscode on the forum you can still find a couple of topics, then everything is bad with debugging. If you know how to debug humanly, then please write me. |

| 19:18:54 | FromGitter | <genotrance> @Jipok: Thanks - I'll try it out. For now, I've just installed vscode and will use it as an editor and continue to build/debug with mingw/gdb. Once I find more time, I'll try building/debugging within VSCode |
| 19:24:16 | FromGitter | <genotrance> wow - Visual C++ 2015 Build Tools needs 4GB of space! why bother? Of course, my msys/mingw directory is 1.5+GB by itself, who knows what all got installed there |

| 19:33:30 | FromGitter | <genotrance> Doesn't help, tried multiple times. First I tried running choosenim from a custom dir, it didn't like the existing versions of libeay I had so I got the version included in the ZIP, then it ran but crashed this way. Then I used the runme.bat to get it "installed" but even then same crash. |
| 19:33:53 | FromGitter | <genotrance> @dom96: https://github.com/dom96/choosenim/issues/35 |
| 19:35:02 | dom96 | Does installing stable work? |
| 19:36:12 | FromGitter | <genotrance> nope, same trick |
| 19:37:08 | dom96 | Strange. Well I'm afraid you'll need to install Nim manually or wait until I fix this :) |
| 19:37:26 | FromGitter | <genotrance> how do I build choosenim? i've cloned it, just to see |
| 19:37:26 | dom96 | btw did you decline to send telemetry? |
| 19:37:32 | FromGitter | <genotrance> no i agreed |
| 19:37:43 | dom96 | hrm, I guess that's another bug |
| 19:38:19 | dom96 | `nimble build` should work. |
| 19:38:58 | FromGitter | <genotrance> ugh, it's downloading the full Nim source code |
| 19:39:05 | FromGitter | <genotrance> I have it setup already |
| 19:40:33 | FromGitter | <genotrance> i have nimble 0.8.6 but it's updating it to 0.8.8 |

| 20:12:25 | FromGitter | <Jipok> Is there any way to simply output any object? Need for debugging |

| 21:59:29 | dom96 | adarezich: `== nil` should be `.isNil()` |
| 21:59:59 | dom96 | `ref seq[T]` shouldn't be necessaru |
| 22:00:01 | dom96 | *necessary |
| 22:00:16 | dom96 | Why isn't `seq[T]` enough? |
| 22:03:42 | Araq | adamrezich: cool but I think slotmaps are inferior to BTrees :-) would make a nice benchmark though |
| 22:04:07 | shodan45 | should I delete my ~/.nimble if I had an old version of nim, like 0.14? |
| 22:04:41 | shodan45 | and just compiled 0.17.2? |
| 22:05:21 | FromGitter | <mratsim> btw @Araq, is there a plan to generate the restrict keyword for seq indexing? |
| 22:08:33 | FromGitter | <adamrezich> @dom96: if it were `seq[seq[T]]` instead of `seq[ref seq[T]]`, when the outer seq grows, the contents inside will move in memory. the point of using a chunked memory system is to avoid that from happening. |
| 22:11:48 | FromGitter | <mratsim> seq is already a pointer so it won’t move? |
| 22:13:31 | FromGitter | <adamrezich> oh, I guess you're right... I think? |
| 22:13:59 | FromGitter | <adamrezich> I'm planning on writing an unsafe version too that uses a `seq[pointer]` and allocates the memory manually, partially just to benchmark the two versions |
| 22:16:04 | FromGitter | <adamrezich> I really *really* like how for simple modules like this, you can write an example at the bottom that also acts as simple unit tests, under a `when isMainModule:` :) |
