01:56:36leorizeAraq: hard code the knowledge about /home? what does that mean?
02:18:31leorizenarimiran: I think nim-lang.org should promote some useful nimble packages. Some of them provide features that a lot of people are asking for (sum types, pattern matching, etc.) and could be a good way to promote how flexible Nim can be
02:18:53FromDiscord_<lmariscal> leorize, the issue is that we don't really have a package registry atm
02:19:01leorizewe do
02:19:04leorizenimble.directory
02:19:15FromDiscord_<lmariscal> sure, a json file
02:19:25leorizeworks well enough :p
02:19:30FromDiscord_<lmariscal> nimble.directory is a mirror of that same json file
02:19:50leorizewith search and docs, really useful :)
02:20:36FromDiscord_<lmariscal> most of the modules I use don't work well with nimble.directory T_T
02:20:46FromDiscord_<lmariscal> they never finish loading haha
02:21:11leorizefederico3 would probably be interested in that :p

06:31:10Zevvhttp://ix.io/1MOO
06:31:28Zevvit's only a few paragraphs but maybe it fits somewhere
06:31:49rayman22201Cool. I'll take a look
06:31:56ZevvHm I now see I never got to the async part even :)
06:31:57Zevvhehe
06:32:59rayman22201lol
06:33:39Zevvmy plan was to start bottom up: first berkeley socket basics, then futures, then the async macro
06:33:53rayman22201Yeah. I am going in the opposite order.
06:35:31rayman22201Reason being, most people probably just want to use existing async libraries. They generally don't need to implement their own.
06:35:57rayman22201good example non the less.
06:36:39rayman22201@narimiran. Yay. Thanks. hopefully I don't stall :-P
06:36:45ZevvI guess it also depends on reader knowledge&experience. If you've ever seen and used async somewhere, which is likely with js and all, it's probably better to start top down
06:37:03ZevvI stall a lot
06:37:08ZevvI probably just start too much
06:38:28AraqVarriount: there is a section about it in manual_experimental

07:05:18VoltistHow would I get a seq of all the keys in a JSON object?
07:05:37VoltistIt doesn't seem to be well documented, if at all
07:10:23leorizeyou can't, sadly
07:10:39leorizewe would need a `keys` iterator for JsonNode then
07:12:00FromGitter<survivorm> @dom96 here?
07:12:10VoltistWould that be hard to implement, do you think?
07:12:27leorizenot at all
07:13:07VoltistWell, this could be my first proper contribution to Nim then!
07:14:05leorizecopy the pairs iterator then modify it to use OrderedTable `keys` iterator and you're set :p
07:14:49VoltistI'll have it done by the hour :]
07:16:34VoltistWell, then there is documentation...
07:17:09leorizepairs() documentation is one line
07:17:54VoltistWere is that found?
07:18:47leorizethe json module
07:18:50leorizehttps://github.com/nim-lang/Nim/blob/devel/lib/pure/json.nim#L776
07:19:00VoltistThanks
07:25:16VoltistSo would we want to the output to be a seq, or a tuple or what?
07:25:58leorizemake the iterator output only strings
07:26:12leorizeuse the keys iterator of orderedtable directly
07:26:26leorizeif anyone wanted a seq they can pass the iterator to sequtils.toSeq
07:26:47VoltistYeah I guess so
07:27:12leorizeyou might want to read up on iterators in the manual :p
07:27:53VoltistI have just recently, but I suppose I just had a slip of the mind
07:28:22VoltistIt's late here, and my brain must have been thinking in terms of procs not iterators
07:29:15leorizeget some rest :)
07:29:43VoltistEventually
07:32:19vegaidid I understood correctly that current Nim doesn't have the concept of destructors?
07:32:27vegaiand only newruntime will fix that?
07:33:18leorizeNim does have the concept of destructors
07:33:21leorizeit's experimental
07:33:50leorizenewruntime on the other hand is an another memory management system built on destructors

07:47:29*couven92 joined #nim
07:47:45vegaioh wait that's silly
07:47:50vegaiit should've obviously been proc `=destroy`(x: var MyObj) =
07:48:10vegaiasking stupid questions publically: almost guaranteed success
07:48:30vegaithe error message was a bit wonky still
07:48:47leorizeyou shouldn't need {.experimental.} for destructors on 0.20
07:49:07vegaiyeah, that seems so
07:49:19vegaiI took that from a year old forum post
07:50:21vegaiso with the classic GC-based nim, that destructor gets called when the GC decides to do its magic
07:51:12leorizenope
07:51:23leorizewell, only if it's a `ref` type
07:51:25vegaishould I be worried that it might never get called? In my case, I'm thinking about building a DB pool, and that destructor would be responsible of freeing a db connection
07:51:42leorizeAraq has changed the rules since
07:51:45vegaiso it would be rather if calling the destructor is delayed
07:52:01vegaiyeah, I tried to read the 2nd edition of destructors, but it's a bit concise
07:52:51vegaiit would be rather bad*
07:53:33vegaiI guess my tests should cover such cases anyway so
07:54:12leorizeif you're not using a `ref object` (and probably shouldn't), then destructors can handle this with GC deterministicly
08:03:04*solitudesf joined #nim
08:13:09livcdleorize: ahh you are right /O thanks
08:16:26vegaileorize: hmm, if I'm handing out DB connections from a common pool to arbitrary threads, doesn't those have to be refs?
08:18:00*brakmic joined #nim
08:18:05leorizeno, and in fact, they shouldn't be `refs`
08:18:28leorizeunless boehm gc is used (which is kinda broken in 0.20 afaik), gc's memory is thread-local
08:18:58Araqhand out a 'distinct int' type that is an index into your seq
08:19:11Araqthe distinct int type can have a destructor, problem solved
08:20:39vegaileorize: I'd be using allocShared, the pool would be shared memory between threads
08:21:08vegaiAraq: ah, that sounds good
08:21:11vegaithanks
08:21:14leorizeallocShared returns a ptr...
08:21:17ZevvWhat happened to the plan to make --threads:on the default?

09:19:12krux02hi
09:19:52krux02@mratsim: yesterday you mentioned something about by pr to change ``shr``
09:20:01krux02I would like to explain my reasoning
09:20:23FromGitter<mratsim> listening
09:20:26krux02ok
09:21:00krux02In C: (x >> y) is undefined behavior if y is negative or bigger than the amount of bits in x.
09:21:35krux02undefined behavior really is undefined behavior, the program doesn't even need to be consistent about it's result.
09:22:22krux02the test had something like (1'u64 shr 64)
09:22:31krux02this was compiled to the >> in C
09:22:45krux02and then the optimizer of c threw away the bitshift
09:23:02krux02sorry I mean shl and <<
09:23:09FromGitter<mratsim> yeah I figured
09:23:32krux02the test was wrong in that respect
09:24:00krux02what I changed is, I applied the bitmask to the right operand, so that the operation won't trigger undefined behavior anymore.
09:24:42krux02this is btw also what other languages do like Java and if I remembor correctly C# as well.
09:25:26FromGitter<mratsim> Ok, I don't mind but I really need the same behaviour at runtime and compile-time
09:26:25FromGitter<mratsim> also I guess shl behaviour should be documented in the manual if defined behaviour is part of Nim specs
09:27:41*Voltist joined #nim
09:31:36krux02yes the bitmasking is done identically at runtime and compiletime.
09:32:10FromGitter<mratsim> Ok well I've removed my request changes review

10:52:06FromDiscord_<Skaruts> A little question:
10:52:32FromDiscord_<Skaruts> I defined two types -- `Rect = ref object of RootObj`, and `House = ref object of Rect` -- in two separate files -- `geometry.nim` and `house_gen.nim`. Rect has a `method intersects(self, other:Rect):bool`
10:52:51FromDiscord_<Skaruts> When I create an instance of House in a third file which imports `house_gen.nim` it doesn't recognize the `intersects` method
10:53:08FromDiscord_<Skaruts> ("error attempting to call undeclared routine")
10:53:14narimiranwild guess: missing export marker? (`*`)
10:53:23FromDiscord_<Skaruts> yes
10:54:07FromDiscord_<Skaruts> I was gonna ask if that's the prefered solution
10:54:45FromDiscord_<Skaruts> the alternative would be to import geometry on all files that need access to the parent type's methods
10:57:10FromGitter<rokups> in order to use something you must mark it with `*` and you must import module that something is in
10:57:14FromDiscord_<Skaruts> oh wait, I misunderstood you, no actually the export markers are all there, problem is that house_gen doesn't have "export geometry" in it (besides "import geometry")
10:59:19FromDiscord_<Skaruts> I mean, I suppose that's what I should do?
11:01:00FromDiscord_<Skaruts> actually it doesn't work that way
11:01:08FromDiscord_<Skaruts> `map_gen\house_gen.nim(4, 8) Error: cannot export: ../geometry`
11:01:57FromGitter<alehander42> you can export
11:02:38FromDiscord_<Skaruts> it's not letting me...
11:02:43FromGitter<rokups> is there `export geometry.*` syntax? docs only say it works for individual symbols
11:03:27FromDiscord_<Skaruts> it works for full files, I'm using that elsewhere, but maybe not in this case, let me see
11:03:53narimiranhow does your `export ...` line look like?
11:04:08FromDiscord_<Skaruts> export ../geometry
11:04:26narimiranremove `../`
11:04:35FromDiscord_<Skaruts> it's in the parent folder
11:04:41narimiranremove `../`
11:05:01FromDiscord_<Skaruts> oh the export doesn't need that!

12:23:51Araqrokups: yeah
12:24:02Araqfor some definition of "same way"
12:24:18FromGitter<rokups> thats awesome. maybe someone will eventually make bindings for vuejs ^_^
12:24:19Araqwe even re-use the importc/importcpp names for it :-/

12:26:16FromGitter<alehander42> hm Araq what is closureScope
12:26:39FromGitter<alehander42> ahh i see
12:27:54FromGitter<rokups> Araq come on... this right here is the reason why nim after more than a decade is not v1.0. you are a mind-blowing engineer, but there is just one of you and you cant write software for every usecase in the world, make it good and maintain it after
12:27:57*theelous3_ quit (Remote host closed the connection)
12:28:29Araqtrue but I got paid to develop Karax and now it already exists
12:28:44FromGitter<alehander42> closureScope invokes a anonimous handler
12:28:45AraqI didn't get paid to make v1 back then
12:28:53FromGitter<alehander42> usually doesnt matter for the javascript backend tho

18:59:54FromDiscord_<Skaruts> the variable isn't nil though I assigned nil to it
19:00:04Araqit is nil.
19:00:14narimiranwhy do you think it is not nil?
19:00:54FromDiscord_<Skaruts> because echo is calling it's type's `$` proc
19:01:15FromGitter<JasperJenkins> being nil doesn't effect something be called. try`$f.isNil` instead
19:01:58Araqshashlick_: it does work afaict. but how do you exit your threads?
19:02:27FromDiscord_<Skaruts> ah yes, isNil returns true

19:05:40FromDiscord_<Skaruts> facepalm
19:08:07shashlick_never mind, i'm an idiot
19:10:14FromDiscord_<Skaruts> is there any performance advantage between using "var" and "let"?
19:10:37FromDiscord_<Skaruts> or does it benefit compile times?
19:19:31Araq'let' can be faster but that's an implementation bug
19:19:45Araq'let' is the better style though
19:20:25zestyr_Araq: I've read a few times `isNil()` is faster, is this true? writing `not obj.isNil()` is uglier than `obj != nil`
19:27:16Araqit's not true

20:25:54Araqyup
20:26:20FromGitter<kaushalmodi> is there a compile time equivalent of for loop?
20:26:46FromGitter<kaushalmodi> the `cImport` from nimterop requires a static string
20:26:58FromGitter<kaushalmodi> so was trying to do: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5d13d512dbd46e037d85a99b]
20:27:02FromGitter<kaushalmodi> but that doesn't work
20:27:43FromGitter<kaushalmodi> ^ above `hFiles` is a `const` too
20:27:57noonienwhat type is a slice of a seq?
20:28:05*jjido joined #nim
20:28:08FromGitter<kaushalmodi> I basically need to derive one const array from another const array, loop through that at compile time and pass that to `cImport`
20:28:18nooniendoes it keep a reference to the data of the initial seq? or does it alloc and copy?
20:28:40shashlick_@kaushalmodi - it's a bit of a challenge
20:28:46Araqit copies but toOpenArray doesn't, noonien
20:29:30noonienOH, nice
20:29:42Araqkaushalmodi: use a macro for that
20:29:42noonienso basically seqVar.toOpenArray(first, last)
20:30:26FromGitter<kaushalmodi> shashlick_: thought so :)
20:30:40shashlick_why does it have to be a const - just use var right
20:30:47FromGitter<kaushalmodi> Araq: looks like I'll need to dig into macros eventually
20:30:56FromGitter<kaushalmodi> shashlick_: cimport requires static string
20:31:03FromGitter<kaushalmodi> so I thought I'd need to use const
20:32:18FromGitter<kaushalmodi> stashlick_: If I use let instead of const in that snippet, I get: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5d13d652aacbfb5fb7d32139]
20:33:29FromDiscord_<Skaruts> @solitudesf oh crap I forgot the call new result
20:33:31FromDiscord_<Skaruts> thanks
20:33:39FromDiscord_<Skaruts> I should get some sleep...
20:35:39shashlick_@kaushalmodi - probably use a compiletime proc or macro - https://github.com/nimterop/nimterop/blob/master/nimterop/cimport.nim#L290
20:36:09shashlick_if you can run cSearchPath() return value can be used, it should be possible
20:37:10shashlick_I had similar challenges in nimdeps - https://github.com/genotrance/nimdeps/blob/master/nimdeps.nim
20:37:53FromGitter<kaushalmodi> shashlick_: thanks! that might work
20:41:03AraqZevv: the compiler could detect it but it's discouraged, use object constructors
20:43:45Zevvok, but even if it is discouraged - would generating a compile time error indicating just that not be better then a runtime error?
20:45:20shashlick_how do i copy a seq into shared memory?
20:45:57shashlick_or even a string for that matter - is there a memcpy
20:46:17shashlick_meh - copyMem

20:55:44noonieni see, and i'm guessing there's no way to slice a string without an alloc
20:55:47AraqZevv: it is easy because we have the infrastructure
20:56:04Araqbut you're right, we would only detect a couple of simple cases

20:58:22Zevvif you are willing to give up safety

21:00:59Araqshashlick_: yes, always
21:03:16shashlick_i'm thinking shared memory across threads - so am wondering if I can assume that the memory is safe to copy as is
21:03:35shashlick_string, sure but for seq, seems like it could contain pointers to stuff elsewhere which wouldn't be shared
