| 08:51:35 | * | taaperotassu quit (Ping timeout: 240 seconds) |
| 08:55:58 | Araq | that means you need to do: var x: cstring; f(x); $x |

| 09:03:20 | Araq | if you need to allocate, why does it take a pointer to a pointer then? makes little sense |
| 09:03:53 | Araq | euantor: yes but don't convert to cstring immediately, save the owner properly |
| 09:04:06 | euantor | ok, makes sense |
| 09:04:50 | * | taaperotassu joined #nim |
| 09:06:37 | FromGitter | <mohamedmoussa89> To be clear the signature could be wrong. So var cstring is actually char**? If i want char* i should simply use cstring? |
| 09:06:50 | FromGitter | <mohamedmoussa89> Char** |
| 09:07:27 | FromGitter | <mohamedmoussa89> Sorry, messing up the formatting it seems. Hope my message made sense. |
| 09:07:31 | Araq | yes |
| 09:07:40 | Araq | var cstring is char** |
| 09:07:47 | FromGitter | <mohamedmoussa89> Alrighty, cheers. That makes sense. |

| 09:08:31 | FromGitter | <mohamedmoussa89> Well actually im working off a Delphi header |
| 09:09:15 | chemist69 | Disclaimer: I am completely inexperienced with Nim macros. |
| 09:09:22 | chemist69 | Has there been a recent change that NimNode.name does not contain the asterisk export marker anymore? |
| 09:09:30 | chemist69 | Because nim-pymod is now always complaining "can't exportpy proc `nim_ext` because it isn't marked for export from the module", when the marker clearly is present in my code. |
| 09:09:40 | chemist69 | I could narrow the error down to these two lines in the nim-pymod source: 1. let proc_name_node = proc_def_node.name; 2. if not proc_name.endsWith("*"):...; |

| 09:27:46 | FromGitter | <Yardanico> @Grabli66 sorry, but also a few things: ⏎ Nim to C is not translation, it's a compilation :) ⏎ And don't use "stmt", it's deprecated |
| 09:28:56 | FromGitter | <andreaferretti> @chemist69 it is just this fix or are you evolving NimPymod? |
| 09:30:39 | chemist69 | andreaferretti: I would love to, but my Nim skills are probably no sufficient for this. Just fixes atm. |

| 09:47:13 | Arrrr | Hello. How can i make sure a proc is not a closure? nosideeffect si too restrictive. |
| 09:48:57 | Arrrr | My usecase is to avoid nested procs to produce closures |
| 09:58:21 | FromGitter | <Grabli66> @Yardanico, i dont agree with you. Nim translates code to C. And then nim call a real compilator, like vcc, gcc, clang. |
| 09:58:42 | FromGitter | <Yardanico> nim is a compiler itself btw |
| 09:59:17 | FromGitter | <Yardanico> maybe gcc is a translator too? it translates C to machine code |
| 09:59:28 | FromGitter | <yglukhov> @Grabli66, then vcc translates c to asm? |
| 09:59:38 | FromGitter | <yglukhov> @Yardanico )) |
| 10:00:13 | FromGitter | <Grabli66> vcc translates to asm? Why? |
| 10:00:56 | FromGitter | <Yardanico> Do you know what "compiler" is ? :) |
| 10:00:57 | FromGitter | <Grabli66> Machine code is not a language. |
| 10:00:58 | FromGitter | <Yardanico> "A compiler is computer software that transforms computer code written in one programming language (the source language) into another computer language (the target language). " |
| 10:01:13 | FromGitter | <Yardanico> source: nim, target: C |
| 10:01:57 | FromGitter | <Grabli66> You are wrong :) |
| 10:03:17 | FromGitter | <yglukhov> @Grabli66: given that machine code has one-to-one correspondence with asm, and asm is considered to be a language.... well... you get the point. |
| 10:03:19 | FromGitter | <Grabli66> Compiler is translator to code near or machine code. |
| 10:03:35 | FromGitter | <Grabli66> Not to another language. |
| 10:06:23 | FromGitter | <yglukhov> another theory. nim produces the binaries in machine code. you don't need to know that it uses gcc under the hood. so why nim is not a compiler if it provides compiler functionality from user perspective? =) |
| 10:06:55 | * | PMunch quit (Ping timeout: 248 seconds) |
| 10:08:29 | FromGitter | <yglukhov> another theory. translation sounds more like one-to-one. e.g. coffescript translates to js and provides little to no additional semantics. nim on the other hand provides a very sophisticated semantics that is not trivial to hand-code in C. |
| 10:08:54 | FromGitter | <yglukhov> actually, impossible =) |

| 10:11:21 | FromGitter | <Yardanico> Back in the mid-80s, I frequented BIX (the BYTE Information eXchange). There was a discussion group for the C programming language, and someone mentioned this new C++ language. I naively asked, "C++? That's a preprocessor, isn't it?" I was thinking of the original Cfront, of course, which translated C++ to C. ⏎ Bjarne Stroustrup jumped in and gently chewed me out: "The Cfront compiler is not a preprocessor! It is a |
| 10:11:21 | FromGitter | ... full-fledged compiler just like any other. Sure, it uses C as the compilation target right now, but it won't always be that way. It could generate native code, but compiling to C let us get up and running more quickly and on more hardware architectures than we could if we targeted machine code right away." |
| 10:12:22 | FromGitter | <yglukhov> And if you trust wikipedia - https://en.wikipedia.org/wiki/Compiler |
| 10:12:33 | FromGitter | <Grabli66> I will never agree, cause i dont want agree. |
| 10:12:53 | FromGitter | <Yardanico> ok then |

| 10:14:36 | FromGitter | <zacharycarter> sounds like nim is a compiler to me |
| 10:15:08 | FromGitter | <yglukhov> as well as coffescript, looks like =) |

| 12:16:17 | couven92 | `koch distrohelper` is the one that creates the Linux install commands, right? |
| 12:25:56 | Araq | couven92: probably yes |
| 12:27:43 | couven92 | I don't know linux! I find it REALLY hard to deal with install.sh asking me where to install... why should I choose `/usr/bin` over `/usr/local/bin` WTF is `/opt` and which one should I choose? |
| 12:27:55 | FromGitter | <Yardanico> btw, I found that there's IdentStartChars and IdentChars in strutils :) |
| 12:28:17 | FromGitter | <Yardanico> and they're actually useful for me |
| 12:29:46 | Araq | couven92: don't install Nim, edit your ~/.bashrc |
| 12:30:07 | Araq | export PATH=/home/me/nim/bin:$PATH |
| 12:30:31 | couven92 | Araq, gladly, but could you elaborate why? |
| 12:32:21 | Araq | because otherwise it's like octopus sex, different parts spread over other parts and it's hard to untangle the mess later |
| 12:32:44 | couven92 | ah, nice metaphor! :) |
| 12:33:18 | FromGitter | <Yardanico> or, as @dom96 would say: "use choosenim" :) |
| 12:34:25 | FromGitter | <Yardanico> but not always |
| 12:34:36 | FromGitter | <Yardanico> e.g. if you use devel almost always, it's better to have raw nim repo |
| 12:34:49 | dom96 | yep |
| 12:35:11 | Araq | does choosenim set the PATH? |
| 12:35:21 | FromGitter | <Yardanico> welp, no :P |
| 12:35:32 | FromGitter | <zetashift> On windows it doesn't |
| 12:35:44 | couven92 | shouldn't it? |
| 12:35:51 | FromGitter | <Yardanico> AFAIK it doesn't do it on linux, but I think it can be implemented for windows |
| 12:35:58 | FromGitter | <Yardanico> for linux it's the mess, so many shells |
| 12:36:09 | FromGitter | <zetashift> I don't know it's really easy to do it manually so I didn't give it second thoughts |
| 12:36:35 | Araq | many users stumble over this. |
| 12:36:38 | dom96 | Indeed, it's so easy you don't even give it a second thought ;) |
| 12:36:43 | dom96 | hear that Araq? |
| 12:37:06 | couven92 | BTW, if I put the repo in /opt/nim, I have to do everything in sudo... But when I do stuff in sudo, the final binaries are not set executable for all users, meaning I afterwards after to run `chmod a+x bin/*` to use Nim normally |
| 12:37:46 | FromGitter | <Yardanico> well you wouldn't do it manually |
| 12:37:56 | FromGitter | <Yardanico> most of the time scripts install programs into /opt and do the same thing |
| 12:39:12 | FromGitter | <zetashift> yeah fair enough ahah, but I guess other users/OSs could have trouble with it. |
| 12:39:47 | FromGitter | <zetashift> I remember rustup(rust's install tool) being able to add the dir to Path on windows |
| 12:39:51 | * | rokups joined #nim |
| 12:40:42 | Araq | zetashift: run finish.exe on Windows |
| 12:40:48 | Araq | it can set the PATH for you |
| 12:41:02 | FromGitter | <Yardanico> hmm, maybe port it to choosenim? |
| 12:41:31 | couven92 | Araq, does it detect if Nim already is in the PATH? There is a hard-limit on the length of PATH you know... |
| 12:41:40 | FromGitter | <zetashift> Ah yea I used choosenim and choosenim says add it to the path, which worked. |
| 12:41:46 | Araq | couven92: it does everythin. |
| 12:41:51 | couven92 | :D |
| 12:42:08 | FromGitter | <Yardanico> lol, I found this |
| 12:42:09 | FromGitter | <Yardanico> https://software.intel.com/en-us/articles/limitation-to-the-length-of-the-system-path-variable |
| 12:42:52 | FromGitter | <Yardanico> on intel website :P |
| 12:43:40 | FromGitter | <Yardanico> hmm |
| 12:43:41 | FromGitter | <Yardanico> The maximum size of a user-defined environment variable is 32,767 characters. |
| 12:43:51 | FromGitter | <Yardanico> There is no technical limitation on the size of the environment block. However, there are practical limits depending on the mechanism used to access the block. For example, a batch file cannot set a variable that is longer than the maximum command line length. |
| 12:43:54 | Araq | Nim's installer still works much better than choosenim ;-) |
| 12:44:45 | dom96 | By what metric? |
| 12:45:00 | FromGitter | <zetashift> I like the ease of handling multiple versions of choosenim |
| 12:45:34 | Araq | dom96: by the "it's not broken" metric. |
| 12:46:03 | dom96 | choosenim isn't broken |
| 12:47:12 | yglukhov | regarding the "broken"... can we do anything about nimble? =) |

| 12:48:25 | dom96 | yglukhov: what's wrong with Nimble? |
| 12:48:43 | yglukhov | my prs not merged? =) |
| 12:50:21 | dom96 | Right. |
| 12:50:50 | Araq | dom96: as long as an issue marked with the euphemism "Araq's wishlist" is open, it's broken |
| 12:51:24 | dom96 | That's not a fair way to label it. |
| 12:53:04 | yglukhov | Bennyelg: your for loop on `peek` doesnt make sense |
| 12:53:19 | FromGitter | <Bennyelg> why? |
| 12:55:32 | * | sz0 joined #nim |
| 12:56:31 | yglukhov | Bennyelg: ok, it kinda does, but youre doing inclusive range |
| 12:56:41 | yglukhov | so your for body is executed 3 times in total |
| 12:56:49 | yglukhov | and the channel has only 2 messages |
| 12:56:51 | FromGitter | <Yardanico> wait, I can't create different object variants based on runtime kind? |
| 12:56:56 | FromGitter | <Yardanico> ah, nvm |
| 12:57:38 | yglukhov | Bennyelg: so third time you'll just hang in recv forever |
| 12:57:51 | * | BitPuffin|osx quit (Remote host closed the connection) |
| 12:58:12 | yglukhov | but anyway, `peek` usage is discouraged |
| 12:58:19 | couven92 | what's the difference between `nim doc` and `nim doc2`? |
| 12:58:22 | yglukhov | not to mention other races in your code =) |
| 12:59:52 | Araq | couven92: 'nim doc2' is what should be used |
| 13:00:02 | couven92 | ok |
| 13:00:54 | FromGitter | <Bennyelg> @yglukhov thanks |
| 13:08:07 | subsetpark | Araq are there any plans to migrate `doc` to `doc2`? |
| 13:08:43 | Araq | subsetpark: I can name 'doc2' to 'doc' and 'doc' to 'doc0' if you want to. |
| 13:08:52 | dom96 | is static[T] stable enough to be used for a Matrix implementation? |
| 13:09:03 | subsetpark | ha, that's a start, but i was referring to removing to `doc` altogether... |
| 13:09:13 | dom96 | there are cases where 'doc2' doesn't work IIRC |
| 13:09:31 | yglukhov | dom96: using it, and relying on it. seems to work. |
| 13:09:37 | subsetpark | so maybe `doc2` -> `doc` and `doc` -> `doc-safe`, something like that |
| 13:09:53 | Araq | it's not 'doc-safe', it's more like 'doc-barbaric' |
| 13:09:59 | subsetpark | or even `doc --safe` |
| 13:10:01 | subsetpark | (or whatever) |
| 13:10:24 | yglukhov | dom96: https://github.com/yglukhov/nimx/blob/master/nimx/matrixes.nim |
| 13:11:41 | dom96 | awesome. There is a basic3d module in the stdlib and it badly needs cleaning up |

| 14:04:10 | FromGitter | <mratsim> And for scientific computing the static dimension is quite restrictive be cause you can't do a collection of matrices then |

| 19:09:57 | PMunch | What're the main differences? |
| 19:10:05 | Elronnd | ....everything? |
| 19:10:10 | PMunch | Haha |
| 19:10:19 | Elronnd | just start playing it |
| 19:10:20 | Elronnd | it's crazy |
| 19:10:22 | Elronnd | it's a wild ride |
| 19:10:32 | Elronnd | you can play at em.slashem.me |
| 19:10:45 | PMunch | Oh wait: "This variant is actively being developed by the one-woman dev team of User:Bluescreenofdeath (a.k.a. Amy). (and more recently User:Elronnd, so a 2 person dev-team now)" |
| 19:10:51 | PMunch | You're one of the devs? |
| 19:11:02 | Elronnd | eh, kind of |
| 19:11:04 | Elronnd | I don't do that much |
| 19:11:10 | Elronnd | amy's the main dev |
| 19:11:20 | PMunch | Uhm, with the link you gave me I just got the nginx default site.. |
| 19:11:29 | Elronnd | ssh [email protected] |
| 19:11:34 | Elronnd | I'll fix it when I get a chance |
| 19:12:20 | PMunch | Haha, that's cool, never thought about running NetHack over ssh :P |
| 19:12:41 | Elronnd | there are quite a few public servers for nethack |
| 19:12:47 | Elronnd | the biggest and most popular is nethack.org |
| 19:12:52 | PMunch | Too bad this keyboard doesn't have a NumPad and is running Dvorak so the keybindings are all kinds of fucked up.. |
| 19:13:26 | Elronnd | you can remap most keys in slex |
| 19:13:32 | Elronnd | all keys but the movement keys, that is :P |
| 19:14:12 | PMunch | Yeah, those are the most important for me to remap :P |
| 19:14:34 | dom96 | oh cool! I should give it a try, only ever played NetHack |
| 19:14:35 | PMunch | hjkl is scattered all around the board on Dvorak |
| 19:14:47 | Elronnd | I looked into making those remappable, but the way you move is, for no good reason, completely different from the way you do other commands |
| 19:15:13 | PMunch | Haha, I guess NetHack and friends have a bit of luggage in their codebase |
| 19:15:17 | Elronnd | yep |
| 19:18:29 | PMunch | I'm actually thinking of writing a small roguelike in Nim |
| 19:18:46 | PMunch | Mostly just to play with terminal graphics and procedural generation |
| 19:19:07 | Elronnd | terminal graphics aren't something you want to play with |
| 19:19:16 | Elronnd | ncurses is kind of a kludge |
| 19:19:27 | Elronnd | you'll want to abstract all the terminal graphics away so taht you interact with them as little as possible |
| 19:20:59 | PMunch | Yeah, but doing that might be fun |

| 19:23:06 | PMunch | Oh yeah I found that zacharycarter while looking around for roguelikes written in Nim |
| 19:23:19 | FromGitter | <zacharycarter> I plan on adding a lot more to it |
| 19:23:21 | FromGitter | <zacharycarter> FOV algos etc |
| 19:23:31 | FromGitter | <zacharycarter> but it may give you a starting point for proc gen if you need one |

| 19:32:12 | FromGitter | <Yardanico> you can use selenium with it's json api |
| 19:32:15 | FromGitter | <Yardanico> it's very highlevel |
| 19:32:32 | FromGitter | <Yardanico> but no, AFAIK no wrappers of phantom js or selenium |

| 19:47:36 | Elronnd | zetashift: I don't like the significant whitespace |
| 19:47:40 | Elronnd | but I like the idea of actual macros |
| 19:47:49 | Elronnd | I haven't actually made anything significant in nim yet |

| 20:16:16 | FromGitter | <krux02> I would be interested if anybody here knows how to publish nim to the web via emscripten |
| 20:16:32 | FromGitter | <krux02> I would like to have an SDL2 application on the web |
| 20:18:45 | FromGitter | <Yardanico> Maybe https://github.com/Jipok/Nim-SDL2-and-Emscripten ? |
| 20:20:00 | FromGitter | <Yardanico> But be aware that "ex211_opengl - Emscripten does not support OpenGL. Only OpenGL ES and WebGL" |
| 20:20:52 | FromGitter | <krux02> isn't WebGL the official opengl ES binding for javascript? |
| 20:21:19 | FromGitter | <zacharycarter> yay got skeletal animation working in webassembly finally |
| 20:21:23 | FromGitter | <krux02> but I am unaware of the version of OpneglES that is webgl |
| 20:21:37 | FromGitter | <krux02> @zacharycarter wow, cool |
| 20:21:56 | FromGitter | <zacharycarter> @krux02 thanks LD |
| 20:21:57 | FromGitter | <zacharycarter> :D |
| 20:22:03 | FromGitter | <krux02> I have skeletal animation, but I would really like to have webassembly support |
| 20:22:49 | FromGitter | <krux02> the problem with skeletal animation, I now have it, but I don't know what to do with it :P |
| 20:22:57 | FromGitter | <krux02> I can't model skeletal animation |
| 20:23:52 | FromGitter | <krux02> I would really like to support WebAssembly in my application, as well |
| 20:24:11 | FromGitter | <krux02> does it support sdl2? |
| 20:25:22 | FromGitter | <zacharycarter> yup |
| 20:25:44 | FromGitter | <zacharycarter> I'm using sdl2 and opengl and it's working well |
| 20:25:51 | FromGitter | <krux02> I recently changed from sdl2 to sdl2_nim |
| 20:25:55 | FromGitter | <zacharycarter> :/ |
| 20:25:59 | FromGitter | <krux02> because I somehow prefer that structure |
| 20:26:29 | FromGitter | <krux02> can you show me the project or is it secret? |

| 20:30:43 | FromGitter | <krux02> @Bennyelg: I have no idea about the database api. So take my advise with a grain of salt. what you do looks quite ok, I would just put the dbtype in an enum |

| 20:49:51 | FromGitter | <zacharycarter> thanks |
| 20:49:54 | Elronnd | it can be defeated through diverse double compiling, https://www.schneier.com/blog/archives/2006/01/countering_trus.html |
| 20:51:10 | Araq | it doesn't have to be defeated because it was never done successfully in practice |

| 20:56:52 | Araq | that's not the Ken Thompson hack IMO. |
