03:54:33FromDiscord<Quantum> probably a stupid question, but for the life of me I can't figure out what the point of the --app flag is
03:54:46FromDiscord<Quantum> what does it do? it doesn't seem to generate anything when I call it
03:55:10disrupteknim --fullhelp | grep app
03:55:20disruptek --app:console|gui|lib|staticlib
03:55:21disruptek generate a console app|GUI app|DLL|static library
03:56:02FromDiscord<Quantum> I saw that, I doesn't really do much when calling ↵> nim --app:gui↵returns an error
03:56:56disruptekit's supposed to omit console output in favor of a gui, but i don't use windows so i cannot tell you how to code the gui part.
03:57:26FromDiscord<Quantum> ohhhhh, I thought is was like a project generation command
03:57:28disruptekyou need to use it along with another compilation command, like `c`.
03:57:37FromDiscord<Quantum> ok that makes more sense

04:19:56FromDiscord<ElegantBeef> for a CLI?
04:21:22FromDiscord<cabboose> Having some weird trouble with the mysql dll. On my development computer it’s all working fine with the dll in the folder of the generated executable; however it does not work similarly on the client computers
04:21:45FromDiscord<cabboose> Both are 64 bit systems with 64 bit dyn library
04:22:04FromDiscord<cabboose> My dev is amd and the client is intel
04:22:07FromDiscord<ElegantBeef> @ProfessorEevee you probably want to use `getCh` from the `terminal` module if that's the case
04:22:19FromDiscord<cabboose> However I tried compiling on a intel dev computer with the same outcome
04:23:29FromDiscord<ProfessorEevee> Yep, this is exactly what I was looking for. Thank you!
04:23:34FromDiscord<ElegantBeef> No problem
04:26:02FromDiscord<ElegantBeef> @cabboose you are copying the .dll over and it's next to the exe?
04:26:09FromDiscord<cabboose> Yes
04:26:41FromDiscord<cabboose> Added the dir to the user path manually too
04:28:07FromDiscord<ElegantBeef> Another case of something outside what i know, can only guess. Which means I guess something like the search path is being hardcoded to the absolute path of the compiled binary, but yea 0 clue so dont believe anything i write
04:30:28FromDiscord<cabboose> Hmmm but the odd thing is that when I compile it on another system it fails again
04:30:42FromDiscord<cabboose> Could there be requirements that aren’t fulfilled for the dynamic library?
04:31:12FromDiscord<ElegantBeef> What modules are you using?
04:32:25FromDiscord<ElegantBeef> I assume since you're using mysql you're using the `-d:ssl` flag, so if you dont have the ssl dlls it'll not work
04:33:29FromDiscord<ElegantBeef> I cannot think of anything else to cause this behaviour, so if that's not it, guess wait untill someone smarter than i steps in
04:33:46FromDiscord<cabboose> Ah that could be it
04:34:41FromDiscord<cabboose> So it’s likely I’ve already got those libraries in my dev computers path but they aren’t present on the client and intel dev computer
04:34:44FromDiscord<ElegantBeef> It should complain about missing stuff
04:34:48FromDiscord<cabboose> I’ll have a crack at that
04:34:55FromDiscord<ElegantBeef> Have you not ran it in terminal to see the output?
04:35:16FromDiscord<cabboose> Yeah; just says “can not load libmysql|libmariadb”
04:35:42FromDiscord<ElegantBeef> Then afaik the SSL isnt the issue 😛
04:36:40FromDiscord<cabboose> Looking at MySQL documentation for the library, the issue might be as simple as not having the correct Visual C redistributable
04:39:21FromDiscord<shad0w> i am gonna get some time on my hands the coming days
04:40:01FromDiscord<shad0w> i was looking into start contributing to the compiler. it'll be a good learning experience i reckon
04:40:39FromDiscord<shad0w> but i guess there's some general ideas about compilers one should have ? i did take a compiler course in college but that was about 4 years ago : P
04:41:30FromDiscord<shad0w> what would some good resources to get started here? i prefer books over videos if that's relevant ?
04:42:42FromDiscord<cabboose> Well the Visual C redistrib didn’t work
04:42:54FromDiscord<cabboose> I’m just going to chuck every bloody library in the file until it opens

10:31:09FromDiscord<ProfessorEevee> How do you use `exitprocs.addExitProc()`? I'm trying to import it, but I can't figure out how to use it
10:36:43FromDiscord<ProfessorEevee> I keep getting `Error: undeclared identifier: 'addExitProc'` :c
10:36:48Zevvimport std/exitprocs
10:37:58FromDiscord<lqdev> we really gotta start adding std/ to all imports in docs
10:38:27Zevvit was never clear to me what goes in std and what does not
10:40:37FromDiscord<ProfessorEevee> ah, I had tried importing std directly but that did not work
10:40:54FromDiscord<ProfessorEevee> I couldn't find that anywhere in the docs, I was so confused
10:42:13Zevvyou should be
10:45:01FromDiscord<ProfessorEevee> Well at first I thought it was by default imported because `import std` didn't work
10:45:17FromDiscord<ProfessorEevee> which I only got from looking at the source code
10:46:03FromDiscord<ProfessorEevee> Then I thought "Hey, maybe it's a nimble package". That wasn't it either
10:46:35ZevvUsually I go to the `tests/` directory and see how things are used. but the docs are clearly lacking here, this module also needs an example or two
10:47:57FromDiscord<ProfessorEevee> also for some reason, I can't do `addExitProc(showCursor)`
10:48:59FromDiscord<ProfessorEevee> sent a code paste, see https://play.nim-lang.org/#ix=2FpH
10:56:20FromDiscord<lqdev> @ProfessorEevee please read zevv's message again and rethink what you're doing.
10:56:27FromDiscord<lqdev> > import std/exitprocs
10:56:36FromDiscord<ProfessorEevee> Oh, I already got that part working
10:56:44FromDiscord<ProfessorEevee> I should've clarified, sorry
10:56:48FromDiscord<lqdev> ah right
10:57:07FromDiscord<lqdev> now, i suppose showCursor is a template?
10:57:33FromDiscord<ProfessorEevee> I have yet to work with templates, so I have no clue what that means or how knowing that can solve my issue
10:57:48FromDiscord<lqdev> oh righty
10:57:56FromDiscord<lqdev> showCursor is a template in the terminal module
10:58:03FromDiscord<lqdev> https://nim-lang.org/docs/terminal.html#showCursor.t
10:58:15FromDiscord<lqdev> you'll need to do `addExitProc proc () = showCursor()`
10:59:57FromDiscord<ProfessorEevee> Hmm, that works, although I have no clue how it works lol
11:00:23FromDiscord<lqdev> you see, the `addExitProc` procedure accepts either a `proc () {.closure.}` or `proc () {.noconv.}`
11:00:41FromDiscord<lqdev> so basically it expects a proc without arguments
11:00:53FromDiscord<lqdev> `showCursor` is the only callable without arguments that matches
11:01:02FromDiscord<lqdev> but it seems that the compiler tries to do something weird :p
11:01:07FromDiscord<lqdev> most likely due to a bug
11:01:25FromDiscord<lqdev> anyways, the compiler seems to match `showCursor`, but it's not a proc
11:01:28FromDiscord<lqdev> which trips it up
11:01:36FromDiscord<ProfessorEevee> So what is `proc ()`? Is that some sort of type casting?
11:01:47FromDiscord<lqdev> that's syntax for closures
11:02:03FromDiscord<ProfessorEevee> Ah, yeah I haven't learned about those either
11:02:08FromDiscord<lqdev> sent a code paste, see https://play.nim-lang.org/#ix=2FpN
11:02:20FromDiscord<lqdev> a closure is basically a local proc that closes over any enclosing local variables
11:02:39FromDiscord<lqdev> closures are also known as lambdas
11:03:07FromDiscord<ProfessorEevee> I see, how.. confusing and weird
11:03:35FromDiscord<lqdev> well we need that because addExitProc expects a proc and showCursor without arguments is a template
11:03:47FromDiscord<lqdev> so we pass it a proc that simply calls showCursor
11:04:07FromDiscord<ProfessorEevee> Ah I see
11:04:25FromDiscord<ProfessorEevee> So it basically creates a proc from the template?
11:04:33FromDiscord<ProfessorEevee> like a sort of wrap?
11:04:56FromDiscord<lqdev> yeah kind of
11:05:13FromDiscord<lqdev> to be more precise, it creates a proc that calls the template
11:05:49FromDiscord<ProfessorEevee> Yeah, that's what I was thinking
11:06:14FromDiscord<ProfessorEevee> sent a code paste, see https://play.nim-lang.org/#ix=2FpO
11:06:31FromDiscord<ProfessorEevee> I assume it's a similar concept
11:06:38FromDiscord<lqdev> that effectively does the same thing
11:06:47FromDiscord<lqdev> it's just that the closure form is shorter
11:06:56FromDiscord<lqdev> and doesn't pollute your scope with an extra proc
11:07:05FromDiscord<ProfessorEevee> Yeah, makes sense
11:07:14FromDiscord<ProfessorEevee> this of course was just as concept and understanding
11:07:25FromDiscord<lqdev> sure
11:07:42FromDiscord<ProfessorEevee> Alright, that's cool. Weird, but cool
11:11:02FromDiscord<ProfessorEevee> Thank you, by the way

11:21:02FromDiscord<exelotl> I might be wrong about that though... I haven't tested it thoroughly
11:22:19FromDiscord<lqdev> @HJarausch_gitlab have you tried doing `mapIt(s, it.origin)`?
11:26:38FromGitter<Vindaar> Yep, or just `s.mapIt(it.origin)` of course. `mapIt` does not take an argument for the type
11:27:48FromDiscord<exelotl> I think they looked at the docs and thought "typed" meant a type is expected 😅
11:29:55FromDiscord<lqdev> oh i didn't notice they added an extra arg

12:25:53hmmmmmhey stupid question: I'm still fiddling with nigui, is there some VScode thingy to see all the procs I can use on a gui element like fontsize etc?
12:27:26PMunchNimLsp and the VSCode plug-in should both have this capability
12:27:33PMunchBut it's a bit, uhm, wonky
12:27:51hmmmmmhmm
12:28:02hmmmmmand how do you do it munchie
12:28:31hmmmmmyou just go to the source of nigui and poke stuff around?
12:30:14PMunchUhm, normally it's just tab
12:30:19hmmmmmoh
12:32:23FromDiscord<inv> stupid question: how to get only one value from iterator? Smth like next(it)
12:32:44PMunchZevv, one feature which would be neat in npeg is passing an enum as a pattern
12:32:54Zevvlike how
12:33:20PMunchSo I don't have to write ("One" | "Two" | "Three") for enum One, Two, Three
12:34:07ZevvHmm but then you'd like to capture the enum insteda of the string I guess
12:34:13Zevvand you want to match style-insensitive?
12:34:55FromDiscord<inv> + how to make it.take(10) ?
12:34:58hmmmmmtab didn't work
12:35:07PMunchI mean optimally I'd want to capture the enum, but if it's not a direct capture that might be hard (e.g. `>("hello_" * MyEnum)`)
12:35:08hmmmmmbut I see there is a thingy called nimsuggest
12:35:08FromDiscord<inv> (edit) "+ how to make it.take(10) ? ... " added "any package ?"
12:35:59PMunchAnd I wouldn't want it style-sensitive (at least not by default), but use the stringified value of the enum
12:37:42FromDiscord<Rika> @inv call the iterator to get the next value
12:37:50PMunch@inv you can quite easily do that with closure iterators
12:37:55PMunchA tad harder with normal iterators
12:38:19PMunchhmmmmm, yeah nimsuggest is what the plug-in for VSCode wraps and what nimlsp uses as a library
12:38:49Zevvhm I'm not sure if npeg has access to the enum type, let me see
12:39:02hmmmmmhmm
12:39:13hmmmmmI already have the extension installed
12:39:16ZevvI find this confing
12:39:23Zevvthe guy called hmmmmm saying hmm
12:39:31FromDiscord<Rika> hmm
12:39:32hmmmmm:3
12:45:39FromDiscord<inv> Just found iterutils, but I think `[range]` would be perfect in iterators
12:45:53FromDiscord<inv> (edit) "Thank you.Just found iterutils, but I think `[range]` would be perfect in iterators ... " added "too"
12:45:56PMunchIsn't it annoying to be called hmmmmm? People have to end up highlighting you from time to time :P
12:46:00FromDiscord<inv> (edit) "iterutils," => "iterutils.slice,"
12:46:15FromDiscord<inv> hmm
12:47:10ZevvPMunch: I don't know if this can work; npeg is untyped so it does not know about MyEnum being an enum
12:48:45PMunchOoh, that's unfortunate
12:49:06PMunchHow do you do Digit/Alpha/Whitespace and all those?
12:49:22FromGitter<HJarausch_gitlab> dumb question? How to terminate an iterator early? (current) Nim doesn't allow a 'return' statement - and using flags to "fall through" would be ugly. Thanks for a hint, Helmut
12:50:18PMunchbreak?
12:50:19hmmmmmoh we are making progress, with ctrl + t, and @ I can find all the symbols I used in my file
12:51:27PMunch@HJ, that was for you by the way :P
12:51:29ZevvPMunch: https://github.com/zevv/npeg/blob/master/src/npeg/lib/core.nim
12:51:32FromDiscord<Rika> How else would you terminate an iterator early
12:53:02PMunch@Rika, with a block and `break blockname`?
12:53:07PMunchOr wrap it in a proc
12:53:46FromDiscord<Rika> Ah, I see, you mean within an iterator
12:54:02FromGitter<HJarausch_gitlab> break doesn't work either : ⏎ iterator domore(x:int) : int = ⏎ if x == 0 : break ⏎ if x == 1 : yield 1 ⏎ yield 2 ... [https://gitter.im/nim-lang/Nim?at=5fbe53eae6f2b51c68b70f11]
12:55:30Zevvno, I don't think it can be done. MyEnum is just an ident
12:55:46hmmmmmeven more progress if I start typing "set" it lists all the procs that start with "set" that I can use
12:56:07PMunchOh from within an iterator!
12:56:10PMunchhttps://play.nim-lang.org/#ix=2Fqd <- this wroks
12:56:12PMunchworks*
12:56:25PMunchAnd if you make it a closure iterator you can use return instead IIRC
12:56:42PMunchZevv, well that's a shame
12:57:23Zevvso, who are you mad at now. Me? Nim? Ar4q? Or shall we just shame disruptek?
12:57:31ZevvI like that option, because he's not here
12:57:53FromGitter<HJarausch_gitlab> @PMunch Yes, this works, thanks! Though I wouldn't call this this ⏎ principle of least surprise.
12:57:59PMunchWell I mean it's not impossible to do, just impractical
12:58:48PMunchI mean even just a special symbol that means "hey this thing is an enum, do some unwrap magic on it later" might work
12:59:12PMunchOr just something I could do to create a subparser from an enum before I create the pattern
12:59:40PMunch@HJ, yeah it might look a bit odd. But that whole iterator is a bit odd..
13:01:29hmmmmmyay got it, I just need to write the start of it like "inputcontainer." and it will suggest the right stuff
13:01:30PMunchI mean you could of course also do it like this: https://play.nim-lang.org/#ix=2Fqk
13:02:04ZevvPMunch: you should be able to make a sub-parser easily
13:02:09Zevvlet me show that
13:11:12hmmmmmwoa F12 opens the definition in the source
13:11:16ZevvPMunch: https://play.nim-lang.org/#ix=2Fqo
13:12:30PMunchOh I was more thinking if I could create it outside of `peg`. That way I could write a macro which does it
13:15:45FromGitter<HJarausch_gitlab> @PMunch This was just a tiny example. I intend to use it in an iterator with nearly 300 lines of code. The next thing I have to find out is how to transfrom a Python 'yield from' to this iterator itself (i.e. recursively) ⏎ into valid Nim code. Any pointers are kindly appreciated.
13:16:06Zevvhttps://play.nim-lang.org/#ix=2Fqq :)
13:16:49PMunchHmm, I guess that kinda works..

14:04:57PMunchThat plus is meant to be in backticks
14:05:41FromDiscord<ProfessorEevee> Well, I want to basically override \`x`

14:09:34FromDiscord<Rika> Well, does it actually run into recursion? Nim uses the most specific procedure there is does it not? And using add over + won’t fix the issue would it?
14:09:56FromDiscord<ProfessorEevee> It does, I had tried it
14:10:11*Kaivo joined #nim
14:10:49FromDiscord<Rika> We don’t have an add, we just strop + if we need an “add”

14:16:24FromDiscord<Rika> You can? Isn’t system automatically imported

19:38:20FromDiscord<AmjadHD> Hi, Is it a good idea for inim to use nimscript instead of compiling and running statements every time ?
19:39:05disrupteki thought you were working on miran's sorta package.
19:41:35leorize@AmjadHD no, nimscript is limited in terms of what you can do
19:41:55leorizebasically anything C FFI won't work
19:42:45FromDiscord<AmjadHD> Yeah I'm aware of that, but I'd argue that typically you'll not use such things in a REPL
19:42:49j-jamesIs there a nice way to regex replace strings one at a time?
19:43:10FromDiscord<AmjadHD> Text editor
19:43:13FromDiscord<AmjadHD> ?
19:43:31leorize@AmjadHD apparently you do, which is why inim exists. For the nimscript-only case we got `nim secret`.
19:44:01FromDiscord<Imperatorn> Binary search is always faster if sorted?
19:45:14j-jamesImperatorn: I'll take a look at that
19:45:19hmmmhey is there a faster way to set an argument as variable inside a proc without needing to manually do something like var foo : int = foo
19:45:50narimiranyeah, omitting `: int` part will be faster
19:46:09disruptekomit the value, too.
19:46:25FromDiscord<AmjadHD> WOW, wasn't aware of that, it's even faster than inim. so that's using the VM (and not compiling) ?
19:47:04leorizeyes
19:47:27FromDiscord<AmjadHD> why is it called `secret`

19:49:14FromDiscord<Imperatorn> Like in groups or just sequential?
19:49:29Zoom[m]disruptek: no, I'm looking at what's in fusion, but thet are authored by narimiran. I'm not sure how different they are, though
19:49:45narimiranZoom[m]: it is the same as `sorta`
19:50:01disruptekfusion is for chumps.
19:50:04narimiranonly generic names are changed to be more like it is for stdlib Table
19:52:56FromDiscord<AmjadHD> So is this `nim secret` a prototype ? that is meant to be improved and eventually exposed to the public ?
19:53:30miprino. otherwise it would given a name that would draw nothing but complaints, so that the complaints could be addresse.d
19:56:46PrestigeHow can I pass an iterator to a function?
19:56:59disrupteksupply it as a parameter.
19:57:12FromDiscord<AmjadHD> but I don't see what's so special about inim, that you think that "it would draw nothing but complaints about how it isn't more like inim" ?
19:57:17PrestigeI was trying something like this: https://play.nim-lang.org/#ix=2FsW
19:57:49disruptekwell, that's not the correct signature for the values iterator.
19:57:54mipriinim works very well and nim secret doesn't at all. I think any but the most trivial interaction should show that.
19:58:48leorizeimport times; let time = getTime() <- run that on nim secret
19:59:11Prestigedisruptek: you mean proc foo's signature is incorrect?
19:59:18disruptekyes.
19:59:28PrestigeIdk what's incorrect about it
19:59:35narimiranx
19:59:50disruptekpretty sure values takes a table.
20:00:22disruptekimmaculate iteration is something that only happens in stories of faith.
20:03:15PrestigeWell I tried changing it, but can't figure out what's missing: https://play.nim-lang.org/#ix=2FsZ
20:03:33disruptekwhat are you trying to do?
20:03:49PrestigeI want foo to be given an iterator it can use
20:03:58narimiranPrestige: this works: https://play.nim-lang.org/#ix=2Ft0
20:06:07PrestigeSo I have to write my own iterator that will just iterate over the tables values? I can't use the Table `values` iterator?
20:06:22disruptekyou can, chucklehead.
20:06:23narimiranyou need closure iterator. `values` is not that
20:06:36disruptekyes, but he can wrap it.
20:07:03PrestigeYeah, I can wrap it, but I can't just use it directly

20:09:03PrestigeUnfortunate if that's the case
20:09:23disruptekwhy?
20:09:27disruptekwho gives a shit?
20:09:32PrestigeMe
20:09:41miprithat's the case. closure iterators are first class; inline iterators are inline. Most iterators that you run into will be inline.
20:09:42disrupteki mean, important people.
20:10:32PrestigeWould be nice if there were a simple way to create a closure iterator from an inline iterator
20:10:44disruptekhow much simpler could it be?
20:10:53PrestigeKeep running into this issue, it's cumbersome
20:11:19disruptekwell, +1 to separating them with a keyword, but that won't happen.
20:11:26disruptekso just write the macro.

21:40:32mipriplease ask the question like it's in your own code. because of course it might be, even if you're intending to closely follow the book.
21:42:24nixfreakI post the code
21:42:37nixfreakany paste works ?
21:43:26miprihttps://play.nim-lang.org/ is pretty good
21:43:45miprithe share link at the bottom left is what I mostly see in here
21:44:57nixfreakhttp://sprunge.us/p3bdva
21:46:43miprithe problem is the space before the parameters to Client, on line 35

21:47:21mipriif there's a space you're passing a single tuple
21:47:59mipriah that error message makes a lot more sense now

21:52:18FromDiscord<j-james> @Imperatorn My use case is to go through an HTML document and replace `` and `_` with their respective tags
21:52:28FromDiscord<j-james> Because there could be a stray `` in a chunk of text, the straightforward method of `replace(html, re(" \"), " <strong>"` and similar doesn't work

22:20:29FromDiscord<For Your Health> Can someone explain to me the reason to use a semicolon in a proc argument list? I can't seem to find any info on that.
22:23:29hmmmoh nice if we asking things why we define procs with the "="
22:23:58disruptekbecause to omit it is to define a prototype.
22:24:06hmmm:o
22:24:22disruptekhealth: semicolons cannot be mistaken for , by humans or computers.
22:25:04disruptekso proc foo(a, b: string; c: int) is easier to parse than foo(a, b: string, c: int)
22:25:16miprithere are only 9 occurrences of 'semicolon' in the manual; look at those and you'll find two reasons to use it.
22:25:46disrupteksee `using`, for one.
22:28:04FromDiscord<For Your Health> I see, thanks! I hadn't seen that section in the manual.

23:57:51FromDiscord<cabboose> Hey @ElegantBeef turns out you were right; the issue was that my dev computer had MySQL with all its dependencies for the libmysql installed which included the ssl and crypt libraries
23:58:30FromDiscord<cabboose> Nim wouldn’t have any complaints since libmysql was dynamically linked and nim has its own ssl
23:59:25FromDiscord<cabboose> I used an application called Dependency Walker to see which dependencies were not available on the client computers compared to the dev computer and packaged the missing dependencies
23:59:29FromDiscord<cabboose> Thanks for your help!
