08:51:10salocinHi I'm new to the nim language. Currently I am trying to install the aporia ide, but the autocomplete doesn't seem to be working, can anyone help? Install nim via the nim exe for 64bit windows and I have 64bit win 10.
08:55:05*Arrrr joined #nim
08:57:37salocinWhen i use the autocomplete function in aporia i get a cmd prompt which close right after opening instead of autocomplete options
09:04:36salocinand i had gtk2 installed prior to installing the nim exe (64bit)
09:12:01salocinanyone here?

09:19:37salocindoes the aporia ide which is provided from the windows binary installer has autocompletion?
09:26:25Araq_it should yes
09:26:42Araq_but it needs to find nimsuggest.exe
09:27:07*Demon_Fox quit (Quit: Leaving)
09:28:29salocini get a cmd prompt which closes immediately
09:35:24salocinand i get the error no items found to suggest
09:36:18Araq_suggestions only work after a dot
09:36:27Araq_foo. # request suggestions
09:36:37Araq_maybe that's the problem?
09:40:26salocindon't think so since it doesn't even work for keywords like echo or string
09:44:06Araq_that's exactly what I'm talking about.
09:44:27Araq_what should be suggested for 'echo'?
09:45:03Araq_or do you want ech and then the completion to 'echo'? that's not what nimsuggest does and aporia doesn't have this feature yet.
09:45:34salocinyes right that is what i meant
09:47:24salocinwill this feature be in the next release of aporia?
09:48:13Araq_not sure but it's something many people stumble over

10:05:32SalewskiAraq, latest nimsugest does name completion fine, at least when started from terminal. If I have "var longname", and I type "lon" sug command displays longname suggestion.
10:07:21SalewskiInstalling nimsuggest is still difficult, but at least it wotks now. When I have some time I will try it with GTK3 sourceview.

10:22:38Araq_Salewski: maybe but that's merely a sideeffect of the "suggest everything" fallback then. iirc.
10:25:55Araq_Salewski: please tell me why installing is still difficult. :-)
10:26:13Araq_you need to put nimsuggest(.exe) next to nim(.exe). done.
10:29:03SalewskiIt is on Linux. I did install a week ago, and was happy I got it working at all, after 15 minutes of trying. Can not remember details, but can do installation again and write down problems.
10:33:35SalewskiOne problem was, that on nimsuggest github page command "nimble build" was given, but for me only "nimble install" worked. And nimble told me that nim compiler was already installed, I had to select reinstall.
10:35:23SalewskiAnd http://nim-lang.org/docs/nimsuggest.html is outdated, nimsuggest is on github now.
10:36:48Salewskihttps://github.com/nim-lang/nimsuggest # Clone this repo and nimble build. No more info there.
10:37:19Araq_aha, very well.
10:37:42SalewskiAnd finally I had to fix the path. Then it was working.
10:38:17SalewskiBye.
10:38:21*Salewski quit ()
10:41:03dom96putting it beside nim(.exe) shouldn't be necessary anymore
10:41:07dom96if it is then that's a bug
10:42:58Araq_maybe but I don't see the point of putting it somewhere else
10:43:33dom96If you're using Nimble already then there is a point.

18:59:52zipR4NDhi all, i am trying to make an object hold a sequence of procs with different signatures .. is there any way to do that?
19:00:35dom96zipR4ND: you can use an object variant to wrap the procs.
19:01:12ldleworkerzipR4ND: but not in the way you're imagining
19:01:24zipR4NDdom96: i see
19:01:27ldleworkersince the signature of a proc affects its type
19:01:31zipR4NDyes
19:01:39zipR4NDand Generics don't help either ..
19:01:40ldleworkerso really with variants you're just making different objects, that each hold one specific proc type
19:01:40dom96zipR4ND: https://gist.github.com/dom96/b1147c09564061dc2323e5bccf516355
19:01:43dom96Something like that
19:01:59dom96Then you can create a `seq[ProcType]`
19:02:20ldleworkerThis will make it so the size of each ProcType value is the size of all the variants put together

19:02:48ldleworkerzipR4ND: Sounds like you want a macro :)
19:03:00zipR4NDhmm, actually yes
19:03:27zipR4NDI'm writing a lexer that will get the callbacks as production rules for regexes ..
19:04:32zipR4NDhmm. ok but I got a direction now, thank you!

21:28:40*libman joined #nim
21:30:05dom96rkj-b: hi
21:34:21nivheey dom96, cool stuff you trying my dodgy little lib
21:35:05dom96niv: :)
21:35:26nivalthough im not sure a distinct type is called for here .. sendText is supposed to receive a string after all
21:35:29dom96I'm making a little multiplayer game with Nim. If I succeed it'll be awesome.
21:36:12dom96niv: well, what I mean is that there should be a `distinct AsyncSocket`
21:36:29dom96called `WebSocket` or something
21:36:36dom96that way I can't accidentally call `send` on it
21:36:51nivoh, the socket, not the payload
21:37:24dom96yeah :)
21:38:21nivthe only thing missing from the lib is per-frame-deflate and similar. its not operation critical, just nice to have. i looked at it but then saw there wasnt any good zlib support in stdlib and thought i'll do it "later"
21:41:09dom96That would be nice. I'm actually wondering whether it would make sense to use a binary protocol for my game.
21:41:36rkj-bGlad _you_ are here!!! I'm a total n00b as I haven't programmed a toaster since year 2000. Why in the world has Nim (which I wish to learn) been exiled from Hacker News and Lobsters. Nim looks like what Go should have been. And it looks like Rust is only for super-secure applications. This troubles me. It even feels like a conspiracy!
21:41:59dom96rkj-b: hah. Why do you think it's been "exiled"?
21:44:52rkj-bWell, there seem to be about three rather trivial articles up about Go and Rust all the time. But I haven't seen a thing about Nim in about two+ months!
21:46:26dom96rkj-b: I think it's because there aren't really all that many new articles being written about Nim.
21:49:40nivdom96: well, sorry about the send socket issue. thats the kind of thing i could never have thought of myself. im glad to hear though its working well for you :)
21:49:58nivdom96: what it doesnt do yet is disconnect handling, so any send/recv call could exception on you. i wonder if i should even add it or let the user handle it
21:49:59dom96niv: no need to be sorry :)
21:50:32dom96I think an exception is sensible anyway
21:51:02nivyeah.
21:51:33dom96You could maybe wrap it in a custom exception or something like that
21:51:45dom96not sure if that's necessary though
21:52:25rkj-bdom96: It seems very clear to me that (almost) no one is going to use Nim if no one hears about it. I think somebody has to start pumping out lots of trivial articles about Nim. And soon!
21:52:57dom96rkj-b: I agree. Wanna be that somebody? ;)
21:54:48rkj-bI'm afraid that would have to be some one who actually, you know, knows what they're doing. (Not me! Maybe in two years.)
21:56:23dom96The problem is that the primary members of the project are far too busy to be writing articles.
22:02:34rkj-bThere must be something that can be done for publicity. Maybe just an announcement every time a new version of the language, transpiler, or Aporia comes out?
22:04:11dom96We do announce every new version of those.
22:05:13dom96I do spend a fair bit of time keeping our Twitter active: https://twitter.com/nim_lang

Tired of Linux and needing to "trust" every one who builds the kernel, distributions, file systems, desktops, systemd, etc. Want PC-BSD so I only have to trust one group!!! So therefor I really...

23:30:05libmanThe version in ports (http://www.freshports.org/lang/nim) is out of date, you should compile from source.
23:33:55libmanSame for OpenBSD (http://openports.se/lang/nim) and Dragonfly (https://github.com/DragonFlyBSD/DPorts/tree/master/lang/nim), but pkgsrc is up to 0.13.0 (https://github.com/joyent/pkgsrc-wip/tree/master/nim).
23:37:23libmanhttps://github.com/nim-lang/Nim/wiki/Consts-defined-by-the-compiler uses "pcc" for Pelles C, but what about https://en.wikipedia.org/wiki/Portable_C_Compiler ? I think the latter is much more important.

23:41:47libmanPortable C Compiler would then be our savior. There's the Amsterdam Compiler Kit (ACK), but I don't know if Nim supports that. Not many choices beyond that: https://en.wikipedia.org/wiki/List_of_compilers#C_compilers

23:43:22libmanTechnically LLVM is under the "University of Illinois / NCSA Open Source License", but as long as it's Copyfree these details don't matter (http://copyfree.org/standard/licenses).

23:44:41Araq_libman: I cannot see Portable C ever catching up
23:45:43Araq_before that happens somebody will fork LLVM and keep it under a copyfree license
23:47:24tautologicohow can I constrain the type of a type parameter? for instance, for requiring that some proc is implemented for the type?
23:47:48libmanPortCC isn't going to catch up in terms of architectures and optimization features, but it could be a clean and sufficient C99 compiler for the OpenBSD types.
