| 06:33:53 | vegansk | Araq, hi! How can I compare two tyGenericBody PTypes? |
| 06:34:14 | vegansk | I found the problem place for issue 88 |
| 06:34:32 | Araq | dunno, compare the pointers t.lastSon? |
| 06:35:12 | vegansk | And now I need to know relations between BaseClass and ChildClass tyGenericBody |
| 06:36:06 | vegansk | The problem is that current implementation compares pointers. But we need to know about their relations, not equality |
| 06:39:03 | * | endragor_ quit (Remote host closed the connection) |
| 06:39:05 | vegansk | Araq, here is the problem line for issue 88: https://github.com/nim-lang/Nim/blob/devel/compiler/sigmatch.nim#L953 |
| 06:39:32 | * | endragor joined #nim |
| 06:40:01 | vegansk | We need to find relation between f.sons[0] and a.sons[0]. Not the equality |
| 06:51:02 | vegansk | Araq, I found relation for direct subclass : ``a.sons[0].lastSon.lastSon.sons[0] == f.sons[0]``. Is it normal way for it? |
| 06:53:35 | Araq | well typeRel computes the subtype relation |
| 06:53:56 | Araq | you just need to invoke it recursively and ensure it return tySubtype or better |
| 06:54:17 | vegansk | No, it returns isNone for this situation :-( |
| 06:54:26 | vegansk | already checked |

| 07:50:07 | Varriount | Hey everyone - I've submitted a Hacker News link to Andrea's Rosencrantz web framework. |
| 07:50:21 | Varriount | https://news.ycombinator.com/item?id=11959437 |
| 07:50:36 | Araq | http://ci.nim-lang.org/ federico3 gave us this |
| 07:50:48 | Araq | testing selected Nimble packages |
| 07:51:51 | Varriount | Does it need a Windows build slave or anything? If so, I think my desktop can handle a bit more. :P |
| 07:52:43 | Varriount | Also, I like the look. No 3 Mb javascript+css file to download. |
| 07:56:59 | * | endragor quit (Remote host closed the connection) |
| 07:57:27 | vegansk | Araq, ok, and please look at PR https://github.com/nim-lang/Nim/pull/4381 one more time. Maybe it's not so bad ;-) At least, it works in all cases |
| 07:58:00 | vegansk | Who selects packages for ci? |
| 07:59:33 | dom96 | Varriount: upvoted |
| 07:59:36 | Araq | there is no telling what it *also* accepts that it shouldn't. it doesn't fix it properly. |
| 07:59:59 | dom96 | This is interesting https://docs.google.com/document/d/1F6oELZcO_ejX2oVk20hmiBWd4lQugfFahn7OOOOyKsw/edit |
| 08:00:08 | Araq | please give me the other solution (maybe in a different PR) |
| 08:00:29 | Araq | and let me see why it breaks with the Data constructor |
| 08:00:42 | dom96 | I wanted to create a similar survey for a while now |
| 08:01:21 | Araq | I know it sucks that the proper fix implies even more fixes in the compiler, but I like to thing it improves quality overall |
| 08:01:31 | Araq | *think |
| 08:03:47 | Araq | alternatively you can try to remove tyContainer and use tyGenericBody consistently in the compiler. |
| 08:04:07 | Araq | since your PR is essentially saying "ok, tyContainer doesn't work" |
| 08:05:36 | vegansk | Ok. Here it is: https://github.com/nim-lang/Nim/pull/4396 |
| 08:09:18 | vegansk | I will return to that issue later. Now issue 88 is the showstopper for me |
| 08:10:01 | euant | dom96: that is an interesting read actually, thanks for sharing it |
| 08:10:15 | dom96 | euant: np :) |

| 08:13:30 | euant | On another note, that PR I submitted yesterday with the many changes wasn't actually line endings when I looked at it. Nimble had taken it upon itself to reorder the entries within almost all of the projects for some reason. |
| 08:13:41 | dom96 | Varriount: You should submit it to reddit too |
| 08:14:04 | dom96 | euant: yeah, I saw that. Very strange. |
| 08:15:26 | dom96 | On an offtopic note: you guys excited about the UK EU referendum? |
| 08:15:38 | PMunch | I would love to see a similar survey for Nim dom96 |
| 08:16:00 | dom96 | PMunch: Awesome. I shall create one :) |
| 08:16:18 | PMunch | It will certainly be interesting to see what they decide, and what will become of the EU if they leave |
| 08:17:03 | cheatfate | Brexit is a bad idea |
| 08:17:12 | dom96 | It will be interesting and scary for me, since I'm still not a UK citizen, if they leave. |
| 08:17:14 | euant | dom96: I'm not sure excited is the right word, perhaps apprehensive? |
| 08:17:20 | * | KaiXBerg quit (Ping timeout: 250 seconds) |
| 08:17:23 | PMunch | If the UK leaves I feel Germany and some of the other big players might leave as well. |
| 08:17:42 | euant | Either way, I voted via postal vote a week or two ago, I knew then what I know now: leaving the EU would be a terrible decision |
| 08:17:44 | dom96 | euant: true. |
| 08:18:05 | cheatfate | PMunch, i dont think so, just because Germany already have changed currency |
| 08:18:27 | PMunch | cheatfate, that's true. It would be painful for them to switch back.. |
| 08:19:00 | PMunch | But they are already pretty mad about having to support countries in the EU they don't feel are "pulling their weight" |
| 08:19:17 | PMunch | Or at least so it seems in the media |
| 08:19:59 | cheatfate | But i think Scotland and Nothern Ireland will exit GB if GB exits EU |
| 08:20:02 | euant | I can hardly blame them for that |
| 08:20:09 | dom96 | I don't think they would leave. It feels like Germany is at the centre of Europe, almost like a leader of it all. |
| 08:20:10 | euant | I can certainly see where they're coming from. |
| 08:20:29 | euant | WIthout Germany, the whole thing would fall apart in my opinion |
| 08:21:03 | dom96 | cheatfate: If Northern Ireland leaves GB then it will become a very scary place indeed, and I live here! |
| 08:21:05 | euant | The UK like to make a lot of noise, but other than that we don't seem to be all too involved. If I remember correctly, a lot of our MEPs have abstained from a lot of European votes in the past |
| 08:21:50 | euant | Scotland are talking about another referendum if brexit happens too, so maybe NI and Scotland can team up and stay in the EU somehow? |
| 08:21:54 | Araq | Germany will never leave the EU. |
| 08:21:59 | Araq | never ever. |
| 08:22:11 | flyx | Germany makes far too much money from it. |
| 08:22:41 | * | bjz joined #nim |
| 08:23:38 | dom96 | The only way I see Northern Ireland leaving GB is if it becomes part of the Republic of Ireland. |
| 08:23:49 | Araq | the Germans are happy to rename their country to "EU" if that's what it takes and be the only member of it. |
| 08:24:05 | dom96 | Which will reinstate the troubles again I bet. |
| 08:24:17 | Araq | because we lost the war. and that's all that matters here. |
| 08:26:33 | flyx | personally, I think GB should either leave the EU or become an actual member instead of insisting on being treated specially |
| 08:26:35 | cheatfate | EU was very good idea, but too slow, any decision of problem must be resolved by 27 parliaments in every country... so one country can block whole EU |
| 08:27:03 | euant | Personally I think the EU is a good idea, but I don't believe the Euro is |
| 08:27:06 | cheatfate | and i think this is main problem of EU |
| 08:27:11 | Araq | In Deutschland kann es keine Revolution geben, weil man dazu den Rasen betreten müsste. |
| 08:27:17 | flyx | EU doesn't really work unless you have an actual economic and foreign politics union. |
| 08:27:54 | Araq | ^ Stalin said it best. ;-) |
| 08:30:18 | flyx | also, Bismarck: Das Wort Europa höre ich oft aus dem Mund von Politikern, die es nicht wagen, ihre Forderungen direkt vorzubringen. |

| 08:47:15 | Araq | just ensure to ask about sexuality and skin color. because skin color doesn't matter. |
| 08:48:31 | euant | Nothing I can think of personally |
| 08:50:25 | dom96 | Araq: hrm? |
| 08:54:01 | Araq | dom96: in other words, don't ask political things. |
| 08:54:52 | dom96 | Araq: Rust asked "Are you part of an underrepresented demographic in technology?", do you think that's acceptable? |
| 08:55:34 | Araq | no, it's not acceptable. |

| 08:55:47 | Araq | it's a political agenda. |
| 08:56:04 | euant | Yeah, I don't really see why you need to ask that in a survey about a programming language? |
| 08:56:57 | dom96 | ok |
| 08:57:06 | dom96 | I won't ask it |
| 08:57:49 | Araq | dom96: you *need* to ask "in your opinion, what's missing for Nim to reach version 1" |
| 08:57:55 | dom96 | ok |
| 08:58:12 | dom96 | What answers should be available for this? |
| 08:58:19 | Araq | a blank line. |
| 08:58:36 | Araq | people should write their thoughts, don't influence them :P |
| 09:00:33 | dom96 | I think most people will be too lazy |
| 09:00:39 | dom96 | Can I add some answers + a text box? |
| 09:01:48 | Araq | ok ok, fine. |
| 09:02:07 | Araq | keep it under 10 questions please, long surveys are horrible |
| 09:03:53 | dom96 | ... |
| 09:03:58 | dom96 | I already have far more than 10 |
| 09:04:06 | dom96 | but I'm keeping all of them optional |
| 09:05:05 | Araq | what? really? :-) |
| 09:06:32 | dom96 | yeah, if people don't feel like finishing it all they can submit only some answers. |
| 09:07:14 | Araq | I don't think people work this way. |
| 09:07:33 | Araq | but fine, since it's about Nim and people love Nim, they will take their time. |
| 09:10:53 | dom96 | Of course they will |
| 09:10:56 | dom96 | Plus, people love me. |
| 09:11:03 | dom96 | They will answer anything I give them :P |
| 09:14:08 | flyx | ask them whether P=NP |
| 09:19:14 | cheatfate | Araq, what is `xor` operation for sets? |
| 09:20:07 | Araq | cheatfate: good question. non-existing 'flip' operator for sets? |
| 09:20:32 | dom96 | flyx: hah |
| 09:20:44 | Araq | flyx: let N=1, P=NP is trivially true. |
| 09:23:23 | cheatfate | Araq, so there no such operation like `xor`? |
| 09:27:40 | Araq | there used to be -+- for "symmetric set difference" iirc |
| 09:27:46 | Araq | which was mapped to xor |
| 09:28:21 | Araq | since A \ B is (A - B) + (B - A) |
| 09:28:41 | Araq | you can re-introduce it, but why do you need it? |
| 09:29:08 | cheatfate | just adopting my code ioselectors.nim to your `sets` |
| 09:29:20 | Araq | I removed -+- since it was buggy and never used anywhere at all. |
| 09:30:13 | Araq | I know you're adapting ioselectors. but what do you use the 'xor' for? |

| 09:32:16 | cheatfate | Araq, do you have windows with vcc? because i think you need take a look on bunch of warnings generated by `vcc` when compiling asynchttpserver.nim |
| 09:33:07 | * | zodiak quit (Ping timeout: 258 seconds) |
| 09:36:36 | Araq | cheatfate: yes. |
| 09:38:43 | cheatfate | Araq, could you check warnings and say `they all safe and could not smash stack for some reason`? |
| 09:39:34 | Araq | cheatfate: later, ok? |
| 09:39:55 | cheatfate | because for month or 2 i've got very strange SIGSEGVs which happening with `vcc` and not `mingw` or happens with `mingw` and not with `vcc` and can be resolved with just adding `echo variable` to code |
| 09:39:58 | cheatfate | Araq, ok |
| 09:40:06 | Araq | what about 'callSoon'? |
| 09:40:29 | Araq | shouldn't that be used to prevent deep stacks? |
| 09:41:46 | Araq | and why is it necessary? you should make futures call 'callSoon' automatically once some recursion counter > threshold |
| 09:42:33 | cheatfate | Araq, problem not in callSoon... |
| 09:42:50 | cheatfate | i have problems in simple tests like 3 calls to await |
| 09:42:58 | cheatfate | and got smashed stack |
| 09:43:17 | cheatfate | but code works perfectly under linux or bsd |
| 09:43:20 | cheatfate | but not on windows |
| 09:46:00 | Araq | wrapped something wrong in winlean.nim? |
| 09:53:37 | yglukhov | given a symbol of type proc, how do i get the type of n-th arg? |
| 09:56:03 | Araq | yglukhov: this bug is not easy to fix and keep compatibility |
| 09:56:28 | Araq | macros.getType doesn't return something that can be used in a type() environment |
| 09:56:45 | yglukhov | Araq: i would be greatful for a workaround as well. because otherwise i'm stuck :( |
| 09:58:29 | Araq | ok, cleanest solution is this: |
| 09:58:44 | Araq | add new magics to ast.nim, mVar, mPtr, mRef |
| 09:59:22 | yglukhov | do you think it's not possible with current compiler? |
| 09:59:32 | Araq | make atomicTypeX in vmdeps.nim:66 set these magics to the produced symbols |
| 09:59:55 | Araq | handle these magics in semtypes.nim, line 1245 following |
| 10:00:15 | Araq | I cannot think of a simple workaround for what you're trying to accomplish |
| 10:00:24 | Araq | and the fix is not that hard, try it please |
| 10:00:49 | Araq | 3 files in the compiler are affected |
| 10:01:22 | yglukhov | Araq: do you think my code in the issue is conceptionally correct? Because i doubt it. |
| 10:01:41 | yglukhov | specifically the need to wrap to type() |
| 10:01:59 | yglukhov | because t[i] should already be a type, no? |
| 10:02:17 | Araq | yes but type() doesn't produce the bug |
| 10:02:24 | Araq | the bug is in getType() |
| 10:02:35 | Araq | so you will have problems either way |
| 10:03:11 | Araq | and my solution is the proper way to fix things and keeps compatibility |
| 10:04:07 | yglukhov | can you describe the other way which breaks compatibility? |
| 10:04:17 | Araq | alright alright, I will do it. just a sec. |
| 10:05:23 | yglukhov | no, i mean, maybe we should really consider fixing getType? but i can't argue on that because i don't understand it enough. |
| 10:06:58 | yglukhov | tbh i don't think backwards compatibility of getType should be of great concern, really. (a) It was introduced not so long ago and (b) nim is under 1.0. |
| 10:10:55 | Araq | I am fixing getType. |

| 10:41:22 | dom96 | euant: maybe I should rename it |
| 10:43:41 | yglukhov | dom96: you forgot to mention rust in "What programming languages are you most comfortable with?". intentionally? ;) |
| 10:43:57 | dom96 | hah no |
| 10:44:01 | dom96 | Also forgot PHP |
| 10:44:32 | Araq | you forgot lots of languages. the list is mostly "hipster" languages :P |
| 10:45:07 | euant | Yeah, I added PHP in "Other" |
| 10:45:38 | dom96 | I'll likely need to clear all responses (sorry euant |
| 10:45:38 | dom96 | ) |
| 10:46:45 | euant | I'll respond when it's public, it's not a problem |
| 10:46:58 | dom96 | cool |
| 10:47:00 | euant | So long as you broadcast it on Twitter and the forums, I'll see it |
| 10:47:01 | dom96 | Added PHP and Rust |
| 10:47:04 | dom96 | anything else? |
| 10:47:21 | vegansk | dom96, haskell? |
| 10:47:27 | euant | I wouldn't just keep adding languages, as otherwise you'll end up with a list several pages long ;) |
| 10:47:52 | dom96 | yeah, but common ones are a must |
| 10:48:09 | Araq | don't list any language |
| 10:48:11 | dom96 | plus I always get annoyed when surveys don't have my language of choice |
| 10:48:14 | Araq | make people write them out |
| 10:48:27 | Araq | C# is not that much work to type anyway |
| 10:48:33 | dom96 | Araq: meh, people are lazy |
| 10:48:43 | Araq | there are no long names when it comes to programming languages |
| 10:48:51 | Araq | if you're lucky they include a vowel |
| 10:50:00 | Araq | yes indeed, it tends to annoy people their language of choice is not listed. hence, list no-one. |
| 10:50:04 | Araq | totally fair. |
| 10:50:58 | dom96 | and then we'll get people writing "Csharp" |
| 10:51:15 | dom96 | federico3 wants me to add "What do you use Nim for? (application domains)" |
| 10:51:19 | * | dom96 thinks that's a good idea |
| 10:51:34 | * | elrood joined #nim |
| 10:51:44 | Araq | so what, Csharp is still understandable |
| 10:51:49 | * | Satyajit joined #nim |
| 10:52:43 | dom96 | Araq: The multi-choice is staying |
| 10:52:46 | euant | Araq: I think the problem comes when using Google's built in graph tools - it'll show "C#" and "Csharp" as two separate things |
| 10:52:56 | dom96 | indeed |
| 10:53:06 | dom96 | Now, any other problems/feedback? |
| 10:53:22 | Araq | I could pick 'other' and write Csharp. |
| 10:53:26 | PMunch | Just got back from lunch and saw you highlighted me Araq, is the survey ready to be taken now? |
| 10:53:47 | Araq | but fine, I'm used to the fact that nobody ever listens to me. |
| 10:53:57 | federico3 | also "what aspects of Nim do you find most useful? ...and weak points?" |
| 10:54:12 | dom96 | PMunch: I highlighted you |
| 10:54:15 | dom96 | It's not ready yet |
| 10:54:18 | dom96 | I just want your feedback |
| 10:54:30 | PMunch | Oh okay :) |
| 10:54:38 | PMunch | I like the control question :P |
| 10:54:45 | dom96 | PMunch: :D |
| 10:54:49 | dom96 | Saw it used somewhere else. |
| 10:55:26 | PMunch | Maybe the editor section should have multiple choices? |
| 10:55:39 | * | Araq will write Csharp |
| 10:55:55 | PMunch | I use Atom for projects but I create files in /tmp and open them in Vim to use as a pseudo-REPL |
| 10:56:39 | dom96 | PMunch: sure |
| 10:56:49 | PMunch | I'm going to set up an automatic compile-and-run on write command thanks to wuehlmaus so it would be even more useful :) |
| 10:56:52 | dom96 | federico3: okay, ideas for the answers? |
| 10:57:20 | PMunch | Maybe just text fields? Otherwise it could be leading |
| 10:57:40 | PMunch | Should the operating system categories include BSD? |
| 10:57:53 | dom96 | PMunch: covered by "Other" |
| 10:58:01 | PMunch | Oh i guess that's true |
| 10:58:24 | PMunch | But it would be harder to graph since people might differentiate between OpenBSD/FreeBSD etc |
| 10:58:31 | dom96 | Hrm, I guess we could just have text fields. But it might be nice to offer answers like "Generics" |
| 10:58:48 | dom96 | PMunch: That's fine, it will be a minority anyway. |
| 10:59:04 | * | Araq will write perl6, Perl6 |
| 10:59:08 | federico3 | dom96: for which question? |
| 10:59:15 | Araq | cause perl6 is just an implementation for Perl6 |
| 10:59:23 | PMunch | dom96, How do you know until the survey is done :P |
| 10:59:32 | Araq | not to be confused with perl-6 which is the 6th version of perl |
| 10:59:33 | dom96 | federico3: For the most useful? |
| 10:59:50 | dom96 | Araq: You write whatever you like |
| 11:00:00 | * | Araq spent some time with Larry Wall ... |
| 11:01:06 | PMunch | Maybe add a "No, but I'm planning to" option for the Nim in action book question? I've only recently started using Nim and I plan on reading it (and possibly buying it). |
| 11:01:08 | dom96 | PMunch: I can time travel :P |
| 11:01:16 | dom96 | PMunch: okay |
| 11:01:20 | PMunch | Haha :P |
| 11:01:21 | Araq | seriously. why do I have ants in my bathroom? |
| 11:01:32 | PMunch | Then why do the survey at all dom96, just give us the answers! |
| 11:02:09 | dom96 | Araq: Because they want to be your friend |
| 11:02:33 | dom96 | PMunch: Because that would create a paradox! |
| 11:02:34 | Araq | the bathroom is in the first floor... |
| 11:02:50 | PMunch | dom96, oh shit, guess you're right. Better avoid that |
| 11:03:03 | federico3 | dom96: development speed / execution speed / memory usage / readabilty / debugging tools / testing tools / packaging / documentation / security / |
| 11:03:04 | Araq | crawling through my walls |
| 11:03:16 | dom96 | federico3: awesome, thanks |
| 11:03:28 | dom96 | federico3: now, what about for the weakness question? |
| 11:04:06 | federico3 | dom96: same answers, so that people can flag each aspect as a pro or a con? |
| 11:04:20 | federico3 | dom96: also "why does Araq has ants in his bathroom?" |
| 11:04:30 | dom96 | federico3: haha |
| 11:04:55 | dom96 | federico3: hrm, okay |
| 11:05:02 | PMunch | Weaknesses: Araq's ants |
| 11:05:44 | PMunch | I hope you're deleting the results from the current survey by the way. I'm just skipping through it :P |
| 11:06:00 | dom96 | PMunch: yeah, I will clear it all before publicising it. |
| 11:06:26 | federico3 | I feel we are not really asking what's Nim good and bad for in terms of application, e.g. microcontrollers, 3D engines, phone "apps"... |
| 11:06:39 | cheatfate | Araq, sorry for interruption... why i can't simply change my "result: ReadyKey[T]" to "result: var ReadyKey[T]" |
| 11:06:53 | PMunch | Hmm, for the domain questions I don't think "None of the above, I'm a student" is a good choice |
| 11:07:09 | cheatfate | Error: expression has no address |
| 11:07:19 | PMunch | I'm a student and I use Nim for hobby and school projects which would fit in one or multiple of those categories |
| 11:07:40 | dom96 | PMunch: true |
| 11:07:43 | dom96 | I'll remove it |
| 11:07:53 | federico3 | ...and what people would want to use it for e.g. "microtrading - but the language is not stable enough" |
| 11:08:35 | dom96 | I think that's covered by the domain question |
| 11:08:41 | PMunch | Maybe keep an option with student |
| 11:08:54 | dom96 | PMunch: Just "Student"? |
| 11:09:01 | PMunch | Hmm |
| 11:09:04 | dom96 | I dunno |
| 11:09:07 | dom96 | I'd rather just remove it |
| 11:09:27 | PMunch | I guess for "What domain do you work in currently" student would be nice |
| 11:09:46 | PMunch | But it can be removed from "What domain do you use Nim in" |
| 11:09:59 | euant | That question didn't really have an answer to fit my role either ;) |
| 11:10:00 | PMunch | That way you can sort on students |
| 11:10:00 | dom96 | ahh yes |
| 11:10:04 | dom96 | that makes sense |
| 11:10:23 | dom96 | ok |
| 11:10:29 | euant | So it should definitely stay multiple choice and have an "other" field |
| 11:10:29 | dom96 | added the most appealing/most displeasing questions |
| 11:10:54 | PMunch | Will they show for people who have said they haven't tried Nim? |
| 11:11:02 | * | kingofoz quit (Ping timeout: 244 seconds) |
| 11:11:06 | PMunch | If so then a "I don't know" option would be nice |
| 11:11:10 | dom96 | which questions? |
| 11:11:23 | dom96 | feel free to try it |
| 11:11:24 | PMunch | The appealing/displeasing ones |
| 11:11:54 | dom96 | No, they shouldn't |
| 11:12:16 | * | kingofoz joined #nim |
| 11:12:45 | PMunch | Oh nice, there are multiple paths :) |
| 11:13:04 | PMunch | "I've never heard of Nim until I got this survey" doesn't sound right |
| 11:13:28 | dom96 | suggestions for an alternative? |
| 11:13:33 | PMunch | I didn't know about Nim prior to this survey? |
| 11:13:40 | PMunch | Or something similar |
| 11:13:45 | PMunch | The sentence just seemed weird |
| 11:13:52 | dom96 | ok |
| 11:14:39 | dom96 | done |
| 11:17:30 | dom96 | Ready for publication? :D |
| 11:19:25 | dom96 | Araq: ^ |
| 11:19:35 | dom96 | Hrm, he must be away dealing with ants. |
| 11:20:14 | PMunch | Haha |
| 11:20:19 | PMunch | It sounds good |

| 12:25:05 | jeffc | Anyone run into this issue before: `lib/pure/strutils.nim(833, 14) Error: could not resolve: line[j .. j + < len(padding)]` |
| 12:25:17 | jeffc | trying to compile for no-os, no-gc (targeting a microcontroller) |
| 12:25:26 | jeffc | Using 14.2 |
| 12:30:12 | PMunch | Uhm, jeffc what is that supposed to do? |
| 12:30:55 | PMunch | j..j doesn't seem right |
| 12:31:29 | PMunch | And I'm not sure if < works like that in later versions of Nim, at least wuehlmaus mentioned something about it the other day |
| 12:34:16 | dom96 | I think the issue is that slicing strings depends on the GC. |
| 12:41:37 | * | bjz_ quit (Quit: My MacBook Pro has gone to sleep. ZZZzzz…) |
| 12:42:02 | * | bjz joined #nim |
| 12:47:01 | PMunch | dom96, I've been meaning to ask about this. How would you do things like string slicing then? In C you could simply use something like malloc + memcpy |
| 12:47:57 | dom96 | Same as you would in C ;) |
| 12:48:01 | PMunch | Is there a way to do such copying in Nim? Just from one array to another, which as little overhead as possible (running a loop to copy the elements separately isn't really a neat solution) |
| 12:48:07 | PMunch | dom96, through FFI? |
| 12:48:19 | dom96 | yeah, I think so |
| 12:51:11 | PMunch | And a C array? |
| 12:53:40 | dom96 | Nim array is equivalent to a C array |
| 12:54:22 | dom96 | PMunch: actually, just use this http://nim-lang.org/docs/system.html#copyMem,pointer,pointer,Natural |
| 12:54:39 | PMunch | Oh, I didn't realize that |
| 12:54:49 | PMunch | But they have to be known at compile time right? |
| 12:55:22 | PMunch | So you can't do array[variable] |
| 12:55:39 | jeffc | PMunch: Not my code, that's in the standard library |
| 12:55:48 | PMunch | That's nice |
| 12:55:53 | dom96 | PMunch: indeed, but you can create an unchecked array |
| 12:55:59 | PMunch | Those functions are exactly what I was looking for :) |
| 12:56:02 | PMunch | Unchecked? |
| 12:56:03 | dom96 | that has no bounds |
| 12:56:21 | PMunch | Hmm, sounds unsafe :P But I guess so are C arrays.. |
| 12:56:23 | dom96 | Depends what you want to do |
| 12:56:29 | PMunch | Obviously |
| 12:56:31 | dom96 | Do you want to malloc an array? |
| 12:56:41 | PMunch | Let's say I did |
| 12:56:53 | PMunch | For creating a data structure for example |
| 12:57:25 | PMunch | Simple linked list in Nim for example (disregarding that it's not really necessary to create one :P) |
| 12:57:35 | jeffc | What sort of sucks is that I don't do any string slicing at runtime, but some of my assertion templates were depending on generating filenames at compile time |
| 12:57:51 | jeffc | It used to work, but broke some time between 13.x and now |
| 12:58:06 | dom96 | jeffc: ahh, then that's a regression, create a bug report please. |
| 12:58:11 | jeffc | Will do |
| 12:59:02 | dom96 | PMunch: well I dunno, you need to give me a bit more details. |
| 12:59:56 | PMunch | Don't actually have any specific cases for this, just wondering |
| 13:00:18 | PMunch | But let's say I wanted to create a persistent data type |
| 13:00:19 | dom96 | If you want to allocate untraced memory then you're on your own |
| 13:00:24 | PMunch | They need to copy arrays around |
| 13:00:28 | dom96 | Nim wraps some functions for you |
| 13:00:34 | dom96 | like alloc and stuff |
| 13:00:43 | PMunch | Okay, I guess that's fair :P |

| 14:37:56 | renesac_ | https://gist.github.com/ReneSac/7059622360bf59ad4415e3c08998bacf |
| 14:38:10 | renesac_ | even if I change addr() to unsafeAddr() the error is the same |
| 14:38:31 | renesac_ | I tried to force the seq to be allocated on the heap too... |
| 14:38:50 | renesac_ | I think it used to work one year ago |

| 15:11:36 | renesac_ | please do when you have time, this is kinda blocking me because I have other code depending on that |
| 15:11:42 | renesac_ | any idea for an workaround? |
| 15:12:57 | Araq | well you need to pass a variable to proc view |
| 15:13:20 | Araq | a const wouldn't do |
| 15:13:36 | renesac_ | I'm doing that |
| 15:14:03 | renesac_ | in my other code the strings to be converted are read from a file |
| 15:14:54 | renesac_ | and in that test I tried to use "s.add(int times.getTime())" to force the s to be on the heap |
| 15:16:51 | Araq | template view*(data: var string | var MemView | var seq): expr = # looks suspicious |
| 15:17:01 | Araq | why overload this thing yet *again*? |
| 15:17:57 | renesac_ | can I give a "default parameter" for a Slice[int]? |
| 15:18:55 | * | endragor quit (Ping timeout: 260 seconds) |
| 15:19:00 | Araq | sure, should work |
| 15:19:17 | renesac_ | I'm looking at the converters now |
| 15:19:25 | renesac_ | ok, got it to compile w/o the converters |
| 15:19:50 | Araq | oh |
| 15:21:49 | renesac_ | updated the gist with the code that compiles |
| 15:22:19 | renesac_ | it seems I also need to implement a equivalent to: proc `^`[T](x: int; y: openArray[T]): int |
| 15:22:38 | renesac_ | but that is another problem |

| 15:23:57 | renesac_ | thanks for the help, do you think I can release that as a nimble package? |
| 15:24:10 | renesac_ | or it is too wrong/dangerous? |

| 15:29:14 | * | KaiXBerg quit (Quit: Page closed) |
| 15:29:23 | renesac_ | ideally, the compiler could support this safely for limited uses, and accept one of these any place it accepts an openarray, but I guess this means a lot of effort |
| 15:30:10 | renesac_ | for now, it seems better than the unchecked arrays people use to interface with C functions |

| 21:44:29 | brechtm | /Users/brechtm/Documents/Code/ray-dog/nimcache/logging.c:31:21: error: use of undeclared identifier 'a' |
| 21:44:29 | brechtm | NSLog(CFSTR("%s"), a); |
| 21:45:04 | brechtm | Anything I can do about this? |
| 21:45:33 | brechtm | I'm using nim 0.14.2 |
| 21:46:56 | PMunch | brechtm, I think we'll need source to help you there.. |
| 21:47:12 | PMunch | It simply seems like a was never declared |
| 21:47:48 | brechtm | Oops... I was assuming logging was part of nim's library. |
| 21:48:00 | brechtm | I'm working with someone else's code... |
| 21:48:44 | brechtm | I know it compiled with nim 0.12 |
| 21:49:14 | brechtm | proc NSLog_imported(a: cstring) = |
| 21:49:14 | brechtm | {.emit: "NSLog(CFSTR(\"%s\"), a);" .} |
| 21:49:24 | brechtm | I think this might be the origin |
| 21:50:22 | PMunch | Okay, and if you call that with NSLog_imported("string")? |
| 21:50:46 | PMunch | Or maybe rather "string".cstring |
| 21:51:31 | brechtm | https://github.com/yglukhov/nim-sdl-template/blob/master/src/nimx/logging.nim |
| 21:52:13 | vktec | Araq: Does `hash()` need to return a string/int/whatever unique to that set of attributes? I assume that's the case. |
| 21:53:07 | PMunch | Oh okay brechtm so if you call it by log("this", "is", "cool") it should work |
| 21:53:32 | brechtm | PMunch: I'm not sure which call is causing the problem |
| 21:53:47 | PMunch | Does it throw that error at compiletime? |
| 21:54:28 | brechtm | yes, clang does |
| 21:54:40 | PMunch | Hmm, strange |
| 21:54:43 | PMunch | Then I'm not sure |
| 21:56:54 | brechtm | PMunch: thanks in any case! |
| 21:58:43 | brechtm | Heh, I changed "a" to "a0" (which is the argument name in logging.c) and it compiles |
| 22:00:27 | brechtm | Why would the current nim version append a 0 to the argument name? |
| 22:03:32 | brechtm | Ah, reading about the emit pragma, I think the 'a' argument should be enclosed in backtick quotes |
| 22:03:46 | Araq | brechtm: it's a regression |
| 22:03:52 | Araq | and happened to work |
| 22:04:00 | Araq | it always needed to be in backticks |
| 22:04:09 | Araq | please submit a PR to this repo |

| 22:13:39 | vktec | Hmmmm.... I have a proc that initializes my struct type. It calls .init() on a HashSet property of said struct, but later on, when I try to call .incl() on that HashSet, I get an AssertionError saying that the set needs to be initialized. Any ideas? |
| 22:15:14 | PMunch | brechtm, thanks for bringing this up by the way. I was thinking of something similar the other day :) |
| 22:15:45 | vktec | Oh, that's wierd! In my init proc, isValid for the HashSet is set to true, but in the proc trying to use .incl, it's set to false... |
| 22:16:03 | vktec | *weird |
| 22:16:19 | Araq | vktec: make your init proc take a 'var' param |
| 22:16:24 | PMunch | brechtm, is that your fork? I would like to follow it |
| 22:17:03 | brechtm | PMunch: https://github.com/brechtm/nim-sdl-template |
| 22:17:35 | vktec | Araq: It returns a new object, unlike HashSet.init |
| 22:17:42 | vktec | So shouldn't need that |
| 22:17:49 | vktec | I think I found the issue though |
| 22:17:58 | PMunch | brechtm, don't be surprised if I add some things to it in the future :) |
