03:38:36shashlickwell I want to be able to extract the existing nim installers posted on nim-lang if possible
03:42:22FromGitter<data-man> Maybe replace installers to 7z self-extracted installers?
03:44:08*lainon joined #nim
03:46:36shashlickit would be easier to simply convert those to .zip files and upload, my latest PR supports binary builds on Windows - https://github.com/dom96/choosenim/pull/63
03:46:58shashlickwonder if dom96 is open to that idea
03:47:46FromGitter<data-man> Araq likes 7z :)
03:58:05shashlickThen we will have to replace untar with nimarchive, then we can extract 7z
03:58:53shashlickI want both choosenim and finish to download the same mingw 7z package
03:59:45FromGitter<data-man> Yes, I propose exactly it.
04:00:16shashlickFinish does the 7z today but that's because the zip contains the 7z binary, choosenim only supports tar gz xz so has its own mingw tar gz it has to download
04:00:35FromGitter<data-man> Can you check nimarchive with 7z installers?
04:00:39shashlickBut first need to get nimarchive to work on Mac and be more robust
04:00:52shashlickSure, will try shortly, why?
04:01:18FromGitter<data-man> Why "why"? :)
04:02:47shashlickWhy post as exe instead of as 7z? So that people who download don't need to have 7zip?
04:02:59shashlickWe don't post an installer anymore
04:03:02FromGitter<data-man> Oh, libarchive configured on Mac may not support .exe!
04:04:19FromGitter<data-man> exe-installers are convenient on Windows. For some users. :)
04:05:16FromGitter<putao88> Has anyone ever used NimData?
04:05:28FromGitter<data-man> Yes.
04:06:30shashlickZip is safest
04:06:41FromGitter<putao88> (https://files.gitter.im/nim-lang/Nim/Blw1/image.png)
04:06:52FromGitter<putao88> I have this problem, I don't know why?
04:06:52shashlickBut you'd expect devs to be able to figure out 7z
04:07:41shashlickThey are checking [0] mostly
04:07:59shashlickFor empty string

09:32:44FromGitter<data-man> We need help! https://github.com/bluenote10/NimData/pull/25
09:34:33FromGitter<survivorm> I've read an article on the code reading psycology and had a thought on that nim is going to benefit from having something like that: http://www.dre.vanderbilt.edu/~sutambe/documents/More%20C++%20Idioms.pdf (ideomatic ways of writing common code fragments). This will improve readability and understanding of nim code. Unfortunately, it needs to be written first :) (I don't volunteer for that ;)
09:36:08FromGitter<survivorm> I'm sure such things are partially covered in manual or Nim in Action, but i don't think it's nearly complete
09:36:44FromGitter<survivorm> And i think it's a good idea for the second book on Nim :)
09:36:51federico3that's what code examples in the manual and docs are for
09:37:20FromGitter<survivorm> The code examples are limited
09:37:30*krux02 joined #nim
09:40:14cremoh, those things listed in pdf are hacks around writing readable code, more like antipatterns.
09:40:41krux02dom96: I just started hexchat, and without configuration it has this alignment/split of messages and user names. So maybe your information about it is a bit outdated.
09:44:42FromGitter<survivorm> I still think some things should be listed. Like getting object from the ref, iterating over object fields, using global variables, and so on. Many, if not all are listed in manual but it's sometimes hard to find. An addition to FAQ would be welcome, i think. But maybe i'm overthinking it

10:43:23FromGitter<survivorm> I'm not a frequent channel listenerm that's why i'm asking
10:45:05FromGitter<survivorm> Thanks a lot. Not like it's urgent, but it's burdening me as unfinished task. I appreciate your time spent on it :)
10:53:19dom96I skimmed the diff again, and found this: https://github.com/nim-lang/Nim/pull/7664/files#diff-91d68bf578ea4bbef60621e73245f542R1008
10:54:26dom96The doc comment isn't finished
10:54:52dom96Also I wonder if we should rename `toDurationParts` and `toTimeIntervalParts` to `toParts`
10:55:54dom96It might be worth defining a TimeIntervalParts type as well.
10:56:06dom96and using range[Nanoseconds..Years] for it?
10:56:18dom96@survivorm ^
10:56:44Electruxmust this chat be exclusively for questions and answers? or general talk can be done too?
10:57:04dom96general talk is fine
10:57:13dom96but preferably if it's Nim-related
10:57:20Electruxah ok thanks :)
10:57:21dom96for offtopic discussions we've got #nim-offtopic
10:57:34Electruxoh... didn't know about that... thanks :D
10:58:04FromGitter<ephja> yay ranges
10:58:40FromGitter<survivorm> @dom96 thanks a lot. I'll fix the comment. I think toParts is fine, but not sure about type for TIParts
10:58:41*Electrux quit (Quit: WeeChat 2.1)

11:00:26FromGitter<ephja> with or without the ability to evaluate assertions at either compile time or runtime depending on what information is available
11:11:27FromGitter<GULPF> @survivorm IMO since toDurationParts returns `array[Nanoseconds..Weeks, int64]` toTimeIntervalParts should return `array[Nanoseconds..Years, int]` for consistency

12:04:06dom96oh, another thing
12:04:12FromGitter<survivorm> ?
12:04:13dom96We should be consistent with C#'s format: https://docs.microsoft.com/en-us/dotnet/standard/base-types/custom-date-and-time-format-strings
12:05:19FromGitter<survivorm> you mean format specifies or function name?
12:05:30FromGitter<survivorm> or something else completely?
12:06:06dom96I mean the 'f', 'ff', 'fff' you've added
12:06:12dom96'fff' should be miliseconds
12:06:20dom96'ffff' microseconds
12:06:25dom96'fffff' nanoseconds
12:07:54yglukhovdom96: pls have a look https://github.com/nim-lang/nimble/pull/497
12:08:08FromGitter<survivorm> @dom96 i think right is 'fff' -> milis, 'ffffff' -> micros, and they don't have specifier for nanos
12:08:32FromGitter<survivorm> If you're telling of consistency
12:09:47*Snircle joined #nim
12:09:50dom96survivorm: possibly. No idea what "ten thousandths of a second" really is :)
12:10:18FromGitter<survivorm> looking at their example helps :)
12:10:40dom96yglukhov: cool, thx!
12:12:25FromGitter<survivorm> but that's rather... not convenient. i'd prefer having an other opportunity, like f^3, f^6 and f^9 for that
12:12:39FromGitter<survivorm> may be - as an option
12:13:25dom96perhaps, but it's better to keep it consistent for now
12:13:34dom96We can add a nicer syntax later
12:14:07FromGitter<survivorm> i mean, to make milis both 'fff' and 'f^3' and so on
12:14:28dom96please just keep 'fff' for now
12:14:40FromGitter<survivorm> okay, you're the boss...

17:32:14Yardanicosorry, sorry
17:32:22FromGitter<kayabaNerve> :P Teasing you
17:32:30FromGitter<kayabaNerve> Good to know. I'll work on that in the future
17:32:41FromGitter<kayabaNerve> I use adblock so I didn't realize it had ads
17:32:49Yardanicoalso it uses JS
17:32:57FromGitter<kayabaNerve> Yeah. That's the main issue I see
17:33:04Yardanico(well, that's not bad for me, but for some people maybe)
17:33:27Yardanicoalso, you've got this crash with last devel? (or 0.18.0?)
17:33:32FromGitter<kayabaNerve> Also, JS has iterators? I know about for (var i in OBJECTorARRAY) but it has something beyond that?
17:33:37FromGitter<kayabaNerve> 1) 18.0 stable
17:33:44FromGitter<kayabaNerve> I uploaded the Git Hash of it lol
17:34:04FromGitter<kayabaNerve> I'm guessing it's an stdlib issue, not a compiler issue

17:36:42LyndsySimonGreetings, Nimmers.
17:37:18TimofffeeHey!
17:37:27dom96hello :)
17:37:42LyndsySimonIs there a popular websockets library?
17:39:07dom96gmpreussner_: IIRC I just wrapped the underlying accessors for len and indexing.
17:39:51dom96LyndsySimon: There is only really one websockets library
17:40:15LyndsySimondom96: What's that? All I see in the stdlib is asyncnet

17:51:17FromGitter<kayabaNerve> I prefer nimrods. Not going to lie.
17:51:35FromGitter<kayabaNerve> Nim stdlib is awesome
17:52:08Yardaniconimrods?
17:52:28FromGitter<kayabaNerve> Instead of nimmers
17:52:54FromGitter<kayabaNerve> I'm still pissed at the lack of C++ sockets
17:55:35FromGitter<kayabaNerve> It's been a language for damn 33 years and there's been proposals since at least 03. Thank Nim for finally giving me a cross platform socket option

18:20:46FromGitter<dandevelo> @kayabaNerve I am doing malloc on purpose as I don't want this to be GC'ed

18:22:09FromGitter<kayabaNerve> I have no idea. Sorry.
18:23:06FromGitter<dandevelo> @kayabaNerve thank you for taking a look at it. I am wondering whether there is a bug in my code or there is a bug in the compiler. Most likely it is in my code but I can't figure out what it is.
18:24:30FromGitter<kayabaNerve> I'll try to play around with it when I get home if you still have the issue.

21:09:47FromGitter<amscotti> Hi, is there an easy way to tell if a value is in a table? In Python, I'm able to do `x in myTable.values()` but in Nim `values` returns a `iterator` and I'm not sure how to check that for the value without looping over all the items.
21:18:40*vivus joined #nim
21:23:27FromGitter<amscotti> This is the code I have right now for checking if there is a value in a table, just want to check to make sure there isn't a better way of doing this build into Nim. ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5b1067cf361a950a662f9156]
21:23:46*thomasross quit (Quit: Leaving)
21:25:03FromGitter<dandevelo> @amscotti did you try: https://nim-lang.org/docs/tables.html#hasKey,Table[A,B],A
21:26:33*Electrux joined #nim
21:26:54FromGitter<dandevelo> @amscotti oh, I misunderstood, you are looking for a specific value. I thought you are looing for a specific key
21:29:28*natrys quit (Quit: natrys)
21:29:40FromGitter<amscotti> @dandevelo Yeah, I just want to know if the value is in the table or not.
21:29:57dom96You could also do: value in table.values.toSeq()
21:30:35*Electrux quit (Ping timeout: 240 seconds)
21:36:50FromGitter<amscotti> I did give that a try, I get an `attempting to call undeclared routine: 'values'` error from the compiler but I think `toSeq(table.values)` works, not sure why.

22:37:58dom96amscotti: try changing from 'const' to 'let'
22:38:00dom96and report this as a bug
22:49:49FromGitter<mratsim> it’s not a bug, it’s template call syntax that doesn’t work as method call in some (all?) situations
22:50:16FromGitter<mratsim> well, it may be a bug, but AFAIK there was no proper solution.
22:52:52dom96it looks like it's crashing the compiler?
22:54:29FromGitter<kayabaNerve> This should be simple. How can I convert a seq to an array?
22:58:14FromGitter<kayabaNerve> Do I have to use a for loop?
22:59:20FromGitter<ephja> x[a..a+n] = y[b..b+n]?
23:06:47FromGitter<kayabaNerve> A splice is just returning a seq

23:07:04FromGitter<kayabaNerve> Thanks
23:14:20FromGitter<amscotti> Still getting errors with a `let`, ⏎ ⏎ ```code paste, see link``` ⏎ ⏎ I think for my code, I'm just going to use the `proc` as it seems to work and is easy to understand.

23:19:41dom96bah, why is Gitter so bad with letting me copy and paste code :(
23:19:56dom96It feels like as soon as GitLab acquired them they stopped maintaining it
