00:04:11FromGitter<zacharycarter> @rayman22201 hrm - is there a docker image for 0.19.0 out?
00:04:17FromGitter<zacharycarter> because that's a relative trivial change to make
00:07:18FromGitter<bung87> I missed you live streaming?
00:10:59*puhuri6 joined #nim
00:12:47*puhuri6 quit (Remote host closed the connection)
00:15:12FromGitter<zacharycarter> no
00:15:17FromGitter<zacharycarter> it's in 11 hours
00:15:25FromGitter<zacharycarter> well 10 hours and 45 minutes I guess
00:15:49*brainproxy joined #nim
00:19:27FromGitter<bung87> ah 7pm in my timezone
00:22:15FromGitter<zacharycarter> I tried to do it early to accommodate as many as possible - but I imagine I screwed over those living west of me in the US
00:22:30FromGitter<zacharycarter> doh well - it'll be recorded
00:23:03FromGitter<rayman22201> Good question about the Docker image @zacharycarter. Idk who produces them / how they are created
00:24:22FromGitter<kdheepak> If I get a user input and am able to convert it to a integer, how to do then use that number for padding a string?
00:25:22FromGitter<rayman22201> 10 hours? Lol. 3am pst? I would love to show my support but I will definitely be sleeping. Lol.
00:27:23FromGitter<zacharycarter> yeah :/ I figured the majority of Nim users are EU based - and plus I like to start early, but I know most of those in the community based in the US will miss it
00:28:00FromGitter<zacharycarter> I'm going to hopefully start live-streaming more, especially once I resume work on a game engine / game
00:28:16FromGitter<zacharycarter> and I'll probably be doing those streams in the evenings
00:30:36FromGitter<rayman22201> No worries. Best of luck! Hope it goes well.
00:31:24FromGitter<rayman22201> It's true. I'm a minority timezone for Nim uses lol. I just have to accept it
00:31:32FromGitter<zacharycarter> yeah - me too :P
00:31:42FromGitter<zacharycarter> but hopefully that changes!
00:31:54FromGitter<zacharycarter> and maybe one day we can have a US based Nim conference or something
00:32:02FromGitter<zacharycarter> my backyard is open
00:32:06FromGitter<zacharycarter> :P
00:32:11FromGitter<zacharycarter> can go grab some beers and fire up the grill
00:32:51FromGitter<zacharycarter> srsly though - it'd be awesome to have a US Nim conference / meetup one day - Varriount and I have met up
00:33:04FromGitter<zacharycarter> but just once, it was for coffee - and then my life got stupid busy for a while
00:34:26FromGitter<rayman22201> A grill and beers is always fun. conference or not :-P
00:34:39FromGitter<rayman22201> You are East Coast US right?
00:35:08FromGitter<rayman22201> I live in Las Vegas actually. One of the conference capitals of the world. I'm just saying :-P
00:35:32FromGitter<zacharycarter> Yeah - Vegas is probably a much more attractive option than Opal Virginia lol
00:36:06FromGitter<zacharycarter> hell - even if we take the closest city to me - DC - Vegas is still a way better option
00:36:43FromGitter<rayman22201> convenient for me, very fun for everybody else. I like this plan :-P
00:37:29FromGitter<rayman22201> too bad no company here would touch Nim with a ten foot pole, but oh well.
00:38:20FromGitter<zacharycarter> well - I don't plan on being where I'm at for long
00:38:29FromGitter<zacharycarter> I'm working on getting my CV / website together
00:38:55FromGitter<zacharycarter> and then hunting for a new gig - either in the game development or systems programming world - whichever door I can kick my foot through first
00:39:10FromGitter<zacharycarter> and I imagine - that will come with re-location unless I find a job at Bethesda or something
00:41:10FromGitter<rayman22201> Well, I can tell you that slot machines have surprisingly terrible C or Java code. I don't work in that industry, but I have several friends that do.
00:42:01FromGitter<zacharycarter> I believe it

05:23:24FromGitter<ephja> "For an object branch switch system.reset has to be used" I'm currently violating this rule for optimization purposes. at least it compiles right now when setting the discriminator directly
05:40:15nc-xephja: https://pastebin.com/vweB7YCg this compiles but gives runtime error `Error: unhandled exception: d is not accessible [FieldError]`. Uncomment `x.kind = b ` and now you get a segfault at runtime. Uncomment ` reset(x)` as well and now it works fine.
05:40:50nc-xSo afaict, you will hit the FieldError or segfault currently.
05:41:30nc-x(Though I don't know if the segfault is a bug or not.)
05:43:24nc-xYou can reassign it using object constructor without using reset() though.

08:12:42stefanos82question: does anyone knows a logging command or option for "./koch tests all"? I've got some error messages and cannot scroll all the way up. Should I rerun my tests and redirect my output to a file of my choice?
08:12:48stefanos82isn't there any simpler option?
08:17:57FromGitter<mratsim> export HISTSIZE=10000
08:18:04FromGitter<mratsim> 10000 lines of scrolling
08:18:41FromGitter<mratsim> or ./koch tests all > output.log
08:19:07FromGitter<mratsim> I don’t remember but you can pipe with the color code included and can open with less -R to still see the colors
08:19:15FromGitter<mratsim> maybe with tee
08:20:42stefanos82we really need a logging mechanism as part of the building / testing process
08:21:15stefanos82it doesn't make any sense to get error messages during the testing procedure without having them all in one place in the form of a table or something alike
08:21:21FromGitter<mratsim> You can add it to testament
08:21:30FromGitter<mratsim> I think that’s one of the plan.
08:22:08stefanos82that's good to know.
08:23:25stefanos82another thing that caught my attention was that certain tests, for instance cycleleak runs on a single core, whereas other tests were using all my CPU cores
08:23:35stefanos82wouldn't make sense to use them all?
08:23:42stefanos82unless there's a reason behind this behavior

08:35:50FromGitter<tim-st> `in expression '1': identifier expected, but found '1' ⏎ type mismatch: got <int literal(2)>`
08:38:22stefanos82@mratsim: another thing I did not know is that we, the devs should "git pull" the latest csourses ourselves. Don't ask me why, but I had the impression "bin/nim c koch" was fetching those latest updates itself lol
08:38:35*dzackg joined #nim
08:39:53stefanos82@tim-st: I have just tested it myself and I personally would consider this behavior as a bug.
08:40:06stefanos82Araq: is this behavior normal?
08:40:27miran@tim-st: it seems that `1* 2` works, but `1 *2` does not. hmmm
08:40:36FromGitter<tim-st> yes, I think so too, although I not really use this
08:40:54*dzackg quit (Remote host closed the connection)
08:41:18stefanos82it must be a bug, because as miran said it works with `1* 2`, even though it throws a warning
08:41:35stefanos82I get `Warning: Number of spaces around '*' is not consistent [Spacing]`
08:42:12stefanos82can you open a ticket @tim-st?
08:42:37FromGitter<tim-st> yes
08:44:03Araqno bug here, echo $x vs echo $ x
08:44:48AraqI mean, the compiler even warns you about it, what are the odds "It's just a bug"?
08:45:06FromGitter<tim-st> no, it doesnt warn on `var x = 1 *2`
08:45:30Araqno, instead it fails
08:45:33FromGitter<tim-st> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5baf3bad1e23486b936021a3]
08:45:42Araqas it's parsed as 1(*2)
08:46:19Araqand that's what the compiler is telling you.
08:46:53FromGitter<tim-st> ok
08:47:09FromGitter<tim-st> just compared to python, there it works
08:48:44*tedski9 joined #nim
08:49:55stefanos82Araq: in other words, `1* 2` is interpreted as (1*)2?
08:50:25*jjido joined #nim
08:50:27AraqPython has to special case 'print', 'await', etc instead
08:50:37Araqto be able to parse 'f a'
08:50:59Araqstefanos82, no because there are no suffix operators in Nim
08:51:56stefanos82Araq: remind me how I can print the parsed code to see this output(?)

08:52:39Araqwhat does that mean?
08:53:27FromGitter<mratsim> @tim-st `1 *2` is parsed like `foo -2` would be parsed

08:53:40FromGitter<mratsim> identifier space unary_op identifier
08:54:05stefanos82Araq: https://github.com/OmniLayer/omnicore/issues/245
08:54:53FromGitter<tim-st> @mratsim but `foo` is not a number
08:55:12FromGitter<mratsim> it’s a NimNode in the AST
08:55:16FromGitter<mratsim> just like 1 is
08:55:35FromGitter<tim-st> I assumed there is a difference between NimNode `1` and NimNode `foo` like category
08:55:44Araqin what universe should a+1 be parsed differently than 1+1 ?
08:55:46FromGitter<mratsim> everything is a NimNode :P
08:56:04AraqI can already hear the screams
08:56:06FromGitter<tim-st> Araq: as we have seen in Python Universe
08:56:11Araq"inconsistent!"
08:56:30FromGitter<mratsim> that would lead to parser special handling rules
08:56:32FromGitter<tim-st> probably Java allows it too and others
08:56:50Araqthat's not how Python or Java handle this
08:56:56FromGitter<mratsim> we already have issues with literals, I don’t want to add parser issues on top
08:57:03Araqinstead they just lack "calling via a space"
08:57:09stefanos82Araq: so `1*2` and `1 * 2` is the proper use, but not `1* 2` or `1 *2`?
08:57:12*ec16 joined #nim
08:57:22FromGitter<mratsim> though the warning “number of spaces is inconsistent” really grates on me

09:00:07FromGitter<timotheecour> @araq as alternative to https://github.com/nim-lang/Nim/pull/9100 would u accept a PR for baseName?
09:00:27Araqif you give it a sane name like lastPathComponent
09:00:40FromGitter<tim-st> btw I think this one is finished: https://github.com/nim-lang/Nim/pull/8778

09:03:18stefanos82this HTML file is sooooo useful!
09:03:28Araq /a/b/c # a is the head, b/c is the tail
09:03:37stefanos82I honestly didn't know about it.
09:03:44leorizeI know, helps me lots when porting Nim over to Haiku :)
09:04:15stefanos82if Haiku wasn't so strict about its C++ syntax...I used have used it a long time ago
09:04:51leorizenow you can forget all about that and use Nim :)
09:04:51stefanos82I think I first saw it back in...2010? oh my, time flies.
09:05:06stefanos82do they plan to use it as their core language?!
09:05:12leorizeno ofc :P
09:05:28stefanos82that's what I meant before -_-
09:05:41leorizeoh
09:05:53AraqHaiku lost me as a user once I figured they have /usr/bin :P
09:06:23leorizethey never have it? :P
09:06:25stefanos82Araq: why's that?

09:19:54leorizethat's the categories lol
09:20:00stefanos82no kidding
09:20:32leorizeyes, you can even check it yourself by comparing with the html
09:20:35Araqthere are some special categories too
09:20:47Araqlike 'lib'
09:20:54stefanos82I see
09:21:16stefanos82therefore we do need to list them as part of tester
09:30:35Araqhmm how can I tell everybody to not merge feature PRs...
09:31:06AraqI think we need .since: "0.19.2" already
09:34:40miranAraq: ...by explicitly telling: "hey people, 0.19.0 is v1.0RC1 (and 0.19.2 is v1.0RC2) and there will be no new features until v1.0 is released"?
09:35:09miran(this is just my guess why you don't want feature PRs ;))
09:35:34Araqa 0.19.2 should only fix the bugs in 0.19, nothing more
09:35:49Araqand I don't believe in manual cherrypicking of bugfixes
09:37:52FromGitter<timotheecour> the longer the time between releases, the more impractical it is to maintain point releases that fix bugs (especially when not cherry picked)
09:38:49FromGitter<timotheecour> especially if it’s 6 months in between
09:39:16FromGitter<timotheecour> alternative is to just fix regressions, not bugs
09:44:10FromGitter<mratsim> At scale we need a feature window and bug fix windows so that you can manage people expectations
09:46:30stefanos82I guess dom96 should start preparing himself to updating his book to introduce 1.0 to the general public

10:13:20stefanos82Araq: so the objective of the latest destructors' implementation is to get closer to C++'s RAII?
10:13:54*nc-x joined #nim
10:14:44nc-xAraq: Whats the reasoning for having gc'ed strings and seqs; and not make destructors the default?

10:49:38*thomasross_ joined #nim
10:50:00FromGitter<tim-st> where is the difference with string destructor compared to how it works now?
10:50:10FromGitter<mratsim> no garbage collection
10:50:17FromGitter<tim-st> like rust?
10:50:25FromGitter<mratsim> or C++, RAII
10:50:44FromGitter<tim-st> do I have to call the destructor or does the compiler insert it where it fits?
10:51:02FromGitter<mratsim> where it fits, it’s the whole point of destructors ;)
10:51:06*FromDiscord_ joined #nim
10:51:14FromGitter<mratsim> otherwise you can just use cstring / ptr char
10:51:30FromGitter<tim-st> where is garbage collection needed then when this will work?
10:51:39*beaumonta joined #nim
10:51:40FromGitter<mratsim> ref types, closures
10:51:54FromGitter<tim-st> ok, I thought string is a ref type too
10:52:09FromGitter<mratsim> currently it is, as are seq, but they have value semantics
10:52:24*mal``` joined #nim
10:52:40FromGitter<tim-st> ok, thanks, does it mean that the string is copied by value always when this is introduced?
10:52:47FromGitter<mratsim> it already is
10:52:59FromGitter<tim-st> when the string is 1gb it is copied?
10:53:13*Sargun_ joined #nim
10:53:16FromGitter<mratsim> except when using `let`, Araq introduces no copy optim that sometimes leak
10:53:41FromGitter<tim-st> ok, thanks, I assume that can improve performance?
10:53:56FromGitter<mratsim> you can do type foo {.shallow.} = object \n data: string if you want shallow copies by default
10:54:31FromGitter<mratsim> the main perf improvement is `move` and `borrow` when the compiler can prove at compile-time that there is no aliasing
10:54:53FromGitter<tim-st> ok, sounds good :)
10:54:55FromGitter<mratsim> you can get huge perf improvement while keeping value semantics
10:55:19FromGitter<mratsim> and without using cheap `let` tricks that fall apart :P

10:57:43*shadowbane joined #nim
10:58:01FromGitter<mratsim> You have to use Rc (reference counting) or Arc (Atomic Ref counting) to keep track of that
10:58:21FromGitter<mratsim> similar to Nim GC or C++ unique_ptr or shared_ptr
10:58:38FromGitter<tim-st> ok, thanks :)
10:58:44FromGitter<mratsim> I’m not sure how their Box types work
10:59:21*nif quit (Ping timeout: 252 seconds)
10:59:55FromGitter<mratsim> it probably rely on Rust lifetime analysis and uses destructors
11:00:27FromGitter<tim-st> yes, the lifetime thing is quite annoying, I like that I dont have to set those things in nim
11:01:10FromGitter<mratsim> you do have to take care of those though otherwise you get either random garbage or SIGSEGV
11:01:16FromGitter<zacharycarter> alright - stream is up - https://www.twitch.tv/zachary_carter - not sure which channel is pluged into it but I'm assuming the offtopic (twitch one)

11:04:29FromGitter<tekjar> Hi. Are the plans of nim without gc still on?
11:04:34FromGitter<kdheepak> Wasn't there a bot that sync'd chat between gitter/irc/discord and twitch?
11:05:35FromGitter<mratsim> twitch is only in offtopic
11:06:17FromGitter<mratsim> @tekjar https://github.com/nim-lang/Nim/issues/7041 GC will still be there, but builtin types won’t use it.
11:08:00FromGitter<tekjar> @mratsim Nice. Does this make using nim on microcontrollers easier?
11:09:24FromGitter<mratsim> I’m pretty sure it will, because you can’t use seq currently if you don’t want to use a GC. ⏎ Also ref types will support a custom allocator so you could create a memory pool with more ease for example
11:14:46FromGitter<tekjar> nice
11:15:17Araq yeah and also, we got system.move in 0.19
11:15:33Araqso you can outsmart the compiler and tell it to move, not copy.
11:15:50Araqbut better than that, the compiler actually produces a warning when it couldn't move on its own
11:16:04Araqso you don't have to litter your code with 'move'.
11:16:33FromGitter<tekjar> Wow nim has move semantics now?
11:17:06Araqnot quite yet, but it's an unfinished beauty IMO
11:18:05Araqthere a precise spec and an implementation that is not too far away from becoming reliable
11:18:09FromGitter<tekjar> Heheh Nim's transition from best of (C, python) to bestof(Rust, python) I guess
11:18:57stefanos82Araq: is there a way to prevent SIGSEGV? I know it's C's behavior, but is there a way to prevent it from happening, like a protective mechanism or something?
11:19:11Araqimport segfaults

12:16:54Araqyou only need to be consistent
12:17:17miran@kaushalmodi: that's what i usually do, or leave out the spaces where it is more readable.
12:17:17Araqkaushalmodi: what's the state of Nim's docs now?
12:17:30mirane.g. `5 * (3+7)`
12:18:15FromGitter<kaushalmodi> Only one PR is remaining to fix the search on devel docs. But that needs to be squashed *and rebased*.. please don't simply merge.

12:20:05FromGitter<kaushalmodi> miran: I am not aware of wrong search results
12:20:18miranlast time i checked, if you search for `strutils`, and click "module strutils", it takes you to some random function inside of strutils module, not the top of the page
12:21:04FromGitter<kaushalmodi> I'd open an issue for that. It's the first time I am hearing. And copy @rayman22201 on that.

13:18:39krux02well it is a bit outdated there is no ``stmt`` anymore
13:19:19FromGitter<zacharycarter> I've read that article a ton of times - and maybe it's just I've learned a lot more since reading it - but I never thought it did a great job of explaining metaprogramming to a newb

13:20:53mirani'm a macro newb, and i think it is quite hard to teach macros, if somebody will just read what have you written, because there are lots of jumps back and forward what you're trying to achieve
13:22:04FromGitter<zacharycarter> well - just conceptually I mean
13:22:14FromGitter<zacharycarter> a lot of programmers don't even get what AST is etc
13:23:47FromDiscord_<Shield> indeed, but parseStmt does help a lot, it's easy to feed the AST human readable strings
13:32:47miran`parseStmt` is nice, but `dumpAstGen` is godsend!

13:47:06Araqso use that and stop trolling us
13:48:12FromGitter<zacharycarter> and compile to windows while you're at it
13:51:07FromGitter<unreadable> Well, no trolling intended. I've actually planned on using nim for a micro service that requires mongo as well though..
13:51:40Araqif you want parallelism, try httpbeast, it got very good benchmark numbers

13:54:02FromGitter<kaushalmodi> HN is hit and miss.. you never know what gets to the front. Crappy articles often get to front page and good articles where the author put in a lot of time and research like this one don't.
13:54:37AraqI can't stand the nested replies of HN and reddit
13:54:49AraqIMO that UI is seriously outdated
13:55:01FromGitter<kaushalmodi> Araq: why? Ctrl+f works

13:55:24miranwell, this article is just a quick overview of nim features. i can understand why there is no discussion
13:55:30FromGitter<kaushalmodi> You get emails when someone replies to you.
13:55:58FromGitter<kaushalmodi> I would search for key words like Nim, and whatever you are interested in
13:56:12FromGitter<kaushalmodi> Example, in static site gen discussions, I search for Hugo
13:56:20Araqwhat?

14:01:05miranstefanos82: well, that's what is the next in line, no? ;)
14:01:06stefanos82Araq said 0.19.1 should be seen as 1.0RC1 and 0.19.2 as 1.0RC2
14:02:59Araqwhat? no, I only meant that we want to release 0.19.2 asap and it's better if no new features are added until that happened
14:03:34*jjido quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
14:04:15miranwell, on monday starts 'hacktoberfest', maybe this is a good opportunity/motivation for users to start contributing bugfixes
14:04:37stefanos82let me check my logs to see how you said this, because I remember reading this before; about not adding new features, but fixing bugs only until v1.0 gets officially released
14:04:59miranstefanos82: that might be what *I* said, and it was just a guess of mine :)
14:05:39stefanos82yep, I was about to say this
14:05:42stefanos82my apologies Araq
14:05:52stefanos82you were clear enough with your immediate reply
14:06:46miranmaybe we can make some 'official announcement' that for hacktoberfest we want to see (only) bugfixes. (probably documentation improvements are also ok, just no new features)

14:11:28stefanos82this is how the core team do this
14:13:00FromGitter<Aaron-JM> Anyone have any ideas for a library that would to see added to nim that I could work on?
14:13:12miranstefanos82: what i'm aiming at is that things like hacktoberfest might be an extra motivation for people to contribute. by stating "we would really like to see bugfixes" you direct that motivation in right direction, which is mutually beneficial
14:14:25FromGitter<zetashift> @Aaron-JM check out https://github.com/nim-lang/needed-libraries/issues
14:14:34stefanos82miran: I wholeheartedly agree with you. What I meant with my aforementioned statement is for future purposes *if* we could use it as a source of inspiration. There are countless projects that have useful procedures we could borrow from

14:17:37Araqso ... how does PHP do it?
14:18:23stefanos82the freeze state? yes
14:18:38Araqyes
14:19:25stefanos82right now they are in the RC cycle and right before the end of December, they will release version 7.3
14:20:45stefanos82Araq: https://wiki.php.net/todo/php73#timetable
14:21:53stefanos82I personally find their strategy quite convenient, because it gives time to users to accept the fact that new features or some critical changes are coming
14:22:17stefanos82therefore they get their code updated right before the official release of new version
14:22:40Araqseems to be a timeline, my question was more about "is there a github feature useful for that"
14:23:03miranyeah, don't click on "merge" button :P
14:23:24AraqI'm not the only one with 'merge' rights

14:32:54Araqyeah, ok
14:34:10stefanos82how about the milestones you are already using?
14:34:22stefanos82as soon as those tickets get closed, you should release v1.0
14:34:47Araqwe have a v1 milestone
14:34:54FromGitter<unreadable> I'll give httpbeast a look. Not sure about the nimongo driver though..
14:35:13FromGitter<unreadable> Anyway, very neat article about nim https://totallywearingpants.com/posts/nim-language-highlights/
14:35:29FromGitter<unreadable> It really makes it shine
14:39:39miranshashlick: so another branch is needed, where new features would go?

15:09:13dom96miran: hacktoberfest event for Nim would be awesome
15:09:17dom96You wanna organise it? :P
15:09:27mirandom96: tell me what i need to do :)
15:09:54dom96Write up an article to post on nim-lang.org
15:10:15dom96Inspiring people to contribute as much as possible during the month
15:10:23dom96giving links to easy issues
15:10:27dom96idea for packages to write
15:10:49dom96(optional) create a graphic that represent's Nim's hacktoberfest
15:11:08miranhacktoberfest is all about pull requests, but packages are also ok i guess (but won't get you a t-shirt :))
15:11:10dom96(optional) offer rewards (stickers) and commit to sending them out to people who make at least one contribution that's valuable

15:12:32mirandom96: ok, let's start small :)
15:13:07federico3miran: you could encourage improving the docs with examples and tutorials
15:13:32miranfederico3: yeah, docs improvements would be great, IMO
15:13:39dom96Sure, just some ideas :)
15:13:57Araqnobody noticed the types in the docs are now hyperlinked :-(
15:14:02dom96just letting you know how far I'm willing to take it, of course we would need to figure out how much that would cost
15:14:23miranbtw, once there was a post in which it was analyzed which nim modules are most frequently used in github repos. anybody remembers that?
15:14:31skellockmiran: yep, i'm going to keep going with the posts
15:14:34Araqmiran, ask GULPF
15:14:37Araqbbl
15:14:57miranit would be useful to know which modules are most used, to first improve their docs
15:18:36miranskellock: nice to hear! if you want more responses on HN and r/programming, maybe spread the posts a bit more. your first one is still 'fresh', and now already we have a second one.
15:19:15skellockmiran: and what if i wanted less responses on HN and r/programming...
15:19:43miranskellock: lol, then tell dom96 to stop spreading links to your articles :D :P

15:39:16dom96and nobody should
15:39:25dom96What people will want is to use a snake_case library with camelCase
15:39:32dom96Any chance you could change the example to show that off?

17:02:29FromGitter<timotheecour> nonpure enum will behave as current pure enum, or the other way around?
17:02:50FromGitter<timotheecour> I hope it’s the former
17:03:05*vlad1777d joined #nim
17:04:26Araqas I've said, all enums will be "Pure, unless the usage is not ambiguous"
17:04:45Araqwhich is consistent with how all of the rest of Nim works.
17:04:57*wildlander joined #nim
17:06:06Araqyeah, I know you don't like it because you found a term to make it look bad ("scope pollution"), that's another discussion then though.

17:08:10*wildlander joined #nim
17:08:20FromGitter<timotheecour> the current (after your modification ~1month ago) pure enum seems like a fine default for all enum; why not use that ? cf https://github.com/nim-lang/Nim/issues/8850
17:08:48Araqyes, we will use that.
17:09:02Araqthat's what I've tried to say.
17:09:14FromGitter<tim-st> Does it mean `EnumType.enumValue` will be recommended way or only `enumValue`?
17:09:44Araqit's up to you
17:09:52FromGitter<timotheecour> ok so then your answer to "nonpure enum will behave as current (as of your 1 month old modification) pure enum” is yes ?
17:10:02Araqyes.
17:10:12FromGitter<timotheecour> Cool.
17:10:14FromGitter<tim-st> I prefer the first one, but I understood from chat that first one goes away so I changed my code and that looks a bit bad
17:13:46*beka15 joined #nim
17:13:48Araqthe idea is that you can write 'x in {Enum.valueA, valueB}' without the more complex scope injection rules that Swift uses (and that break in DSLs)

17:31:37FromGitter<kaushalmodi> c2nim.html does not exist in doc/html when I do koch docs
17:32:20Araqtrue, it's a separate project
17:32:47FromGitter<kaushalmodi> ok.. should that be part of koch docs?
17:33:17AraqIMO no. but how to handle external links is unclear
17:33:31FromGitter<kaushalmodi> https://nim-lang.github.io/Nim/c2nim.html is 404
17:33:43Araqas I said, ideally we also link to popular Nimble packages
17:33:48FromGitter<kaushalmodi> so need to add c2nim generation to before_deploy in Travis
17:34:16Araqsounds more like your link checker should special case c2nim?
17:34:26FromGitter<kaushalmodi> yes, I can add an ignore
17:34:32FromGitter<kaushalmodi> but needs to fix devel docs too?
17:34:34FromGitter<kaushalmodi> or not?
17:34:53FromGitter<kaushalmodi> btw for external link collection, I can suggest a simple toml file
17:34:55FromGitter<kaushalmodi> example: https://github.com/kaushalmodi/ox-hugo/blob/master/doc/data/users.toml
17:35:21Araqhmm the link to c2nim should just be absolute
17:35:29Araqthat would fix it too, right?
17:35:33FromGitter<kaushalmodi> yes
17:35:48Araqok, that's a good solution then
17:35:59FromGitter<kaushalmodi> cool
17:36:27FromGitter<kaushalmodi> and see the above toml suggestion for external links.. then we can collect/maintain ext links from one place
17:36:37*anamok joined #nim
17:36:39anamokhi
17:36:42FromGitter<kaushalmodi> and have a way to fetch an ext link using a toml key
17:37:17Araqhmm isn't this more helpful for the Nim website?
17:37:22anamokHow to convert a mutable seq[int] for instance to an immutable one? And vice versa?
17:37:29Araqwhich is in its own repo now, remember.
17:38:05FromGitter<kaushalmodi> yes, I haven't touched that repo. I am just suggesting a general solution for data collection
17:38:42mirananamok: `var a = @[1, 2, 3]; let b = a` ?
17:38:47Araqanamok, mutability is not an aspect of the type, but of the "symbol kind", 'let' is immutable, 'var' is mutable, as a parameter it's immutable unless you use a 'var' parameter
17:40:56*leru joined #nim
17:44:19FromGitter<codenoid> how to take enum as argument with T
17:44:41anamokmiran: that will be an immutable view. If you add something to `a`, that'll be visible in `b` too. How could you have an immutable copy of `a`?
17:44:56mirananamok: i don't think so
17:45:08Araqanamok, that's a long outstanding bug

17:48:04Araqmiran, and now do the same in a 'main' proc :P
17:48:37miranAraq: ouch!!
17:48:58Araqyeah I know. unfortunately my compiler relies on this bug :P
17:49:27Araqnow that we are getting a move optimizer we can finally fix it though without too bad performance regressions
17:49:37FromGitter<codenoid> i want enumerable arg from proc
17:49:38miranis there a remedy for this? in python that would be using `deepCopy`
17:49:39FromGitter<codenoid> get
17:49:49Araqmiran, type 'var' instead of 'let'
17:50:29miranoh, i totaly abandoned snake_case it seems :D when did that happen? (in python it would be `deep_copy`, of course :))
17:50:52AraqI think it's deepcopy in Python
17:51:29miranAraq: yeah, `var` does the trick, but anamok asked about making it immutable.
17:51:34Araqhttps://docs.python.org/2/library/copy.html#copy.deepcopy
17:52:11miran`var temp = a; let b = temp`? :D
17:52:49_0ffhhi all, i'm new! i tried to rtfm, but i can't seem to find how i can get to the intermidate c code of my nim programmes (for cross compilation to anther platform)
17:53:23mirannot only did i forget about snake_case, i also forgot the names of python functions! ;) this is a testament about the power of nim, and how much do i use it
17:53:56miranhaven't written any meaningful python in a quite long time now
17:55:31anamokmiran: thanks for the example. So `var b = a` makes a copy of `a`.
17:58:09elroodAraq, don't really want to be that guy, but i still get close to 6k broken links in the docs, and that's only the local ones. those to the github sources seem to lead into cloud 404 as well. just saying, however, to be frank i'd just ignore this for now tho, it's doesn't really have a lot of motivation potential for the weekend

18:06:25stefanos82miran: it slices an array to N pieces, depending on each_slice() passing argument
18:07:02*kemurphy19 quit (Remote host closed the connection)
18:07:09stefanos82basically it slices an existing array every N steps
18:07:47stefanos82for instance, an array of 10 elements, 1, 2, 3, ... 10, will produce [1,2, 3], [4, 5, 6], [7,8,9], and [10]
18:08:04Araqelrood, please be more precise? Which links are 404s? Are you sure it's not your browser's cache?
18:08:35Torticea = (1..10).each_slice(2) do |i| puts i end outputs [1, 2] [3,4] [5,6] [7,8] [9,10]
18:08:42elroodkaushalmodi, does that include checking for fragment identifiers (#someid)?
18:10:33miranstefanos82: Tortice: so it is `chain` in reverse direction? :) i don't know if something like that exists
18:13:25mirani might add something like that to 'itertools' if there's interest
18:13:34elroodAraq, won't completely rule out any local problems on a saturday evening, but koch docs generated links akin to https://github.com/nim-lang/Nim/edit/devel/stats.nim and https://github.com/nim-lang/Nim/tree/master/nre.nim here
18:15:25FromGitter<kaushalmodi> elrood: I manually checked few fragments and they worked. The tool (htmltest) has a bug that gives false failures with local fragments
18:15:34FromGitter<kaushalmodi> so I disabled them
18:15:44stefanos82miran: think of it this way: "slice this existing array, each of generated ones of 3 elements"
18:15:51FromGitter<kaushalmodi> elrood: can you give an example of broken local fragment
18:18:44FromGitter<kaushalmodi> elrood: I think nre is not published anymore

18:37:53stefanos82nothing happens
18:38:59FromGitter<adam-r-kowalski> @Araq in the manual I see we have concepts like Enumerable, AdditiveMonoid and other useful definitions, but are they defined under some module in the standard? Or where can I take a look at the ones already defined
18:40:45Araqthere are none in the stdlib
18:41:06anamokmiran: here is the bug I ran into: http://ix.io/1nR4 . However, if you run it in the global space, i.e. without a main function, it gives the expected result.

18:41:39mirananamok: yep, that's what Araq has pointed out earlier
18:42:08FromGitter<adam-r-kowalski> Oh my bad, is there some discussion I can read about or something that talks about them in more detail? I tried googling around but I wasn’t able to find much yet. Are we planning on utilizing them throughout the stdlib at some point? Like openarray seems like a perfect use case for a concept.
18:42:35mirananamok: ugly hack is to do `var temp = a; let b = temp` var copies, and then let makes it immutable

18:58:03stefanos82question: why are we using <?xml version="1.0" encoding="utf-8" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> in place of <!doctype html> which is supported pretty much everywhere?
18:58:06FromGitter<kaushalmodi> In Travis, you just `curl` to get the binary of the tool and run it.. takes <1 min to run it
18:58:21FromGitter<kaushalmodi> +1 to what stefanos82 said
18:58:39*MarderIII joined #nim
19:02:24Araqstefanos82: legacy
19:02:57stefanos82also, the reason the aforementioned links do not work is an old issue with docs already reported back in July
19:03:07stefanos82https://irclogs.nim-lang.org/20-07-2018.html
19:03:22stefanos82data-doc-search-tag
19:04:13FromGitter<kaushalmodi> stefanos82: the data-doc-search-tag definitely exist in the latest theindex.html
19:04:16FromGitter<kaushalmodi> do you want to try it out
19:04:18FromGitter<kaushalmodi> ?
19:04:27*bartholin12 joined #nim
19:04:29stefanos82I'm browsing the live documentation
19:05:12FromGitter<kaushalmodi> Araq: *final* 1 error, newly introduced by nre :)
19:05:15FromGitter<kaushalmodi> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5bafccebc7bf7c36628f576b]
19:05:49FromGitter<kaushalmodi> Araq: let me know what you think about htmltest to Travis
19:05:59FromGitter<kaushalmodi> as you see above it took just 3 seconds to find that single 404
19:06:20FromGitter<kaushalmodi> it uses cache and Travis allows caching any dir
19:06:37Araqwould be nicer if we could use nim's parsehtml to do that
19:06:38FromGitter<kaushalmodi> It you don't consider a Go-built binary to add this check, I can submit a PR
19:07:03FromGitter<kaushalmodi> when we can a Nim solution, we would of course replace htmltest with that
19:07:40Araqwell a Nim solution is maybe 20 lines of code
19:07:45FromGitter<kaushalmodi> *If you don't consider a Go-built binary as a blasphemy
19:08:07FromGitter<kaushalmodi> this utility does a lot of other checks
19:08:10FromGitter<kaushalmodi> see its readme
19:08:59FromDiscord_<deech> Small thing but I recommend also including the MIT license in it's own file at the root of the project.
19:11:50*bartholin12 quit (Remote host closed the connection)
19:12:28FromGitter<kaushalmodi> elrood: I am also ignoring the Github source/edit link checks for now because the htmltest is too fast.. causes github server to return HTTP 429 error codes :P
19:12:44Araqer...
19:12:53Araqthat's a denial of service attack then
19:13:27Araqbetter not add this to travis just yet.
19:13:37FromGitter<kaushalmodi> yeah.. it's too fast.. I have suggested the dev to not check the same link again: https://github.com/wjdp/htmltest/issues/105
19:13:54FromGitter<kaushalmodi> it's just unnecessary to check the same URL again
19:14:05Araqit's not "too fast", it's a poor crawler
19:14:24TorticeIs this an okay implementation? http://ix.io/1nRm
19:14:32FromGitter<kaushalmodi> well.. at least it helped fix the Nim docs
19:15:05FromGitter<kaushalmodi> except for the GitHub links there is a good amount of confidence that right now *only 1* link is broken in Nim docs :D
19:15:16Araqsure but this thing runs 20x a day
19:15:21Araq*would run
19:15:35FromGitter<kaushalmodi> can be conditioned to run it just once a day in travis
19:15:42Araqwe can add it to the "nightlies" checks
19:15:44miranTortice: use `openArray` instead of `seq` so it works also on arrays and strings. i would use generics (`[T]`) instead of `auto`
19:15:46FromGitter<kaushalmodi> I don't know how.. but pretty sure there's a way..
19:16:11FromGitter<kaushalmodi> You can are fine adding htmltest, I'll find a way to make it run once a day
19:16:28FromGitter<kaushalmodi> (and ignore github checks till the dev fixes that issue)
19:16:41miranTortice: there is also `..<` operator so you don't have to do `i+n-1`, and you'd have `i ..< i+n`
19:17:43FromGitter<kaushalmodi> Araq: And https://github.com/nim-lang/Nim/pull/9110 is passing tests, rebased and ready for merging
19:17:50FromGitter<kaushalmodi> then the search will work on devel docs too :)
