00:54:03user0_Hi
00:54:28user0_I was wondering if debugging nim is complicated due to cross compilation to C
00:54:42ipjkuser0_: https://nim-lang.org/blog/2017/10/02/documenting-profiling-and-debugging-nim-code.htm
00:54:46FromGitter<bogen> @adamrezich: you can pass in any Nim variable or data structure. (anything that you can pass on normal Nim function call)

02:07:41adam12@zacharycarter IIRC, you were cross compiling somewhere/how?
02:21:55FromGitter<zacharycarter> docker
02:22:10FromGitter<zacharycarter> adam12: ^
02:22:42adam12@zacharycarter were you using a pre-build image? I thought I remember you were building for windows or something. One of your games?
02:23:18FromGitter<zacharycarter> yeah I was building my own image and installing Nim on it and everything needed for cross compilation
02:23:49FromGitter<zacharycarter> then mounting my Nim project on the vfs and compiling it on the image and outputting the result to afolder
02:24:45adam12@zacharycarter you see dockcross at all?
02:25:58FromGitter<zacharycarter> yeah - rolling my own images was easier but I wasn't too familiar with docker when I did all this, it might be beneficial now not sure
02:26:41FromGitter<zacharycarter> those images don't have Nim installed on them but they might be good base images to start from
02:26:45FromGitter<zacharycarter> who knows
02:26:55FromGitter<zacharycarter> putting together your own image for CC should be pretty trivial
02:27:16adam12@zacharycarter Yeah. I'm targetting Freebsd. A bit more problematic. Working with Vagrant right now
02:27:50FromGitter<zacharycarter> ouch okay I can see that being painful
02:29:00adam12It is for local builds I guess. I could probably send it off to a server somewhere

07:02:23gokrI must say I have felt a bit of frustration when it comes to multithreading these last few days.
07:03:47gokrI have a hard time landing on a nice architecture - and I keep banging against inexplicable (to me) GC-safe errors. The last lesson learned was - make sure any forward declarations use {.gcsafe.}
07:04:51gokrI also bumped into the circular import issue which ... after scratching my head - got me into dumping all the code into a single module.
07:07:25Arrrrwelcome abroad

07:09:17gokrAnyone using sharedtables btw?
07:09:34gokrI even briefly considered just using redis for sharing ;)
07:20:44Araqyes, people use sharedtables, what's wrong with them?
07:21:17gokrNothing wrong - just trying to get more info, find some howto or something
07:21:29Araqforwarding wrt .gcsafe is annoying yes, but I am not sure how to improve it.
07:22:18*claudiuinberlin joined #nim
07:24:01gokrIn that particular case we may just add a small note to the error message - "Nim can not infer GC-safety from forward declarations, so make sure to add gcsafe pragmas to the declarations if needed" - or something.
07:24:49gokrIt felt like I hit my head against other GC-safe mysteries, but... I am not sure.

08:04:28gokrThe setupForeignGC thing was promising, but... as its written right now with the context thing being passed to the C library for the callbacks - it doesn't work.
08:04:54gokrBut that would probably be a trivial thing for someone like you Andreas to fix.
08:18:26Araqwhere can I find the code?

08:38:56PMunchAh, that's better :)
08:39:21PMunchHaven't had time to read the entire thing yet, but looking forward to it
08:39:40PMunchIIRC a lot of people have mentioned debugging as one of the things that Nim could be better at
08:39:56dom96yep :)
08:40:35PMunchLooking into creating a new kind of cross-platform GUI platform by the way. Heavily relying on Nims macros and posibly also things like concepts
08:41:58PMunchSo that would be one more tick in the boxes of wanted features :)
08:50:04PMunchIt will even be able to create HTML UIs so that we can create UIs over all of Nims export targets :)

09:02:57Calinouhi :)
09:03:21CalinouI found that https://micro-editor.github.io/ can lint Nim code, this is pretty nice for quick edits :P
09:06:38gokrAraq: Sorry, was looking elsewhere. It's here: https://github.com/barnybug/nim-mqtt/blob/master/src/mqtt.nim#L126-L169
09:07:28gokrAraq: So... the wrapper is quite fine I think, but AFAICT it doesn't fly with the asynchronous style using this setCallbacks() call that the library offers.
09:08:09gokrI added the setupForeignGC thingy in the three callbacks in there, for example here: https://github.com/barnybug/nim-mqtt/blob/master/src/mqtt.nim#L142
09:08:34gokrBut the problem AFAICT is that this code is not GC-safe - it will fail if you try to build it using --threads:on
09:09:02gokrThe example is here: https://github.com/barnybug/nim-mqtt/blob/master/examples/callbacks.nim
09:09:40gokrI think the core issue is the "context" thing that needs to be passed into the C library. The CallbackContext.
09:10:17gokrThe current code happily creates that guy and passes it in - but... the callbacks being made from the C library are of course in new threads that the C library creates.
09:10:54Araqit's not GC safe at all
09:11:01gokrright
09:12:15gokrI now fell back to using this wrapper synchronously - but in its own Thread in Nim with a channel talking to it. It works fine for now for me, but... it would be good to try to get this wrapper a bit more happy.
09:13:03gokrMQTT usage is growing a lot these days - given its dominance within IoT areas. And it's a pretty neat clean small pub/sub protocol.
09:13:22gokrAnd the Paho libraries (that this wrapper uses) is basically de facto standard.
09:14:23gokrI am not presuming you have time to spend of course, but it would be enlightening to know how we handle these things generally (callbacks from C libraries).
09:15:58FromGitter<mratsim> I'm looking into config file format: yaml, toml ... It's a jungle. I like toml. Similar to .ini, comment are using #. Datetime are datetime, two different syntax for arrays and arrays of variant.
09:18:24*xet7 quit (Quit: quit)
09:18:29gokrmratsim: Stumbled over: https://github.com/crdoconnor/strictyaml/blob/master/FAQ.rst#why-not-use-toml
09:18:38*xet7 joined #nim
09:20:56CalinouYAML is a very complex specification, also it has some ambiguity for users
09:21:06Calinoulike, truthiness can be specified with a lot of "strings"
09:22:21Calinouhmm, 1.2 spec doesn't mention it: http://www.yaml.org/spec/1.2/spec.html
09:22:42Calinoubut I've heard that some implementations allow using "y", "yes", "on", "true"… as boolean `true`
09:22:59Calinouand since you don't have to put strings between quotes, it can be pretty confusing
09:23:47FromGitter<mratsim> @gokr appart from being able to do [[1,2],["hello","world"]], I don't agree with the strictyaml criticism. Syntax typing is a feature not an issue
09:25:00gokrI have no real view on the subject :) What's your current take then?
09:25:39Calinouthat said, I like YAML as an user, but TOML is fine to me too
09:25:43Calinouas long as it's not JSON :)
09:25:44*claudiuinberlin quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
09:25:54Calinou(I don't think JSON is a good format for configuration)
09:28:19FromGitter<mratsim> Still exploring, looking for a format so that user can specify URL to load deep learning model, and data
09:28:48FromGitter<mratsim> Json doesn't support comments (implementation dependant) so ....
09:29:17*claudiuinberlin joined #nim
09:29:32FromGitter<mratsim> Toml or ini files seems the best for the moment
09:29:42Araqmratsim: I don't write programs that can be "configured", write libraries instead ;-)
09:32:20FromGitter<mratsim> I do ;) but I'm thinking of future use cases, like you have a library of models (maybe even stored on GitHub) and you want to load one. I will obviously provide a function for that but it might be useful to provide a confusing file
09:32:25FromGitter<mratsim> Config
09:38:20gokrHehe "provide a confusing file" - what a fitting typo ;)
09:39:04*claudiuinberlin quit (Quit: My MacBook has gone to sleep. ZZZzzz…)
09:44:05FromGitter<andreaferretti> @dom96 great article! Finally all info that is needed for profiling and debugging collected in one place :-)
09:44:38FromGitter<andreaferretti> It should be linked from https://nim-lang.org/documentation.html though
09:55:40*libman quit (Quit: Connection closed for inactivity)
09:58:13Araqgokr: callbacks to C libraries that are executed on unknown threads need to be .gcsafe as well as call setupForeignThreadGc
09:58:31FromGitter<mratsim> debugEcho !!! wow that's awesome debugging noSideEffect proc was a pain
09:58:55gokrAraq: Yes, I understand that. I am just not sure how to modify mqtt.nim so that it works.
09:59:18Araqoh it's not easy, the design is wrong
09:59:44Araqhe relies on a global holding closures that's as GC unsafe as it can get

10:48:28PMunchHmm, is it possible for one macro to store information for another macro?
10:48:38PMunchie. have a compile time global variable
10:49:48Araqit is.
10:50:11Araqit's also super anti modular and will eventually break our back
10:50:35Araqbut you know the saying, in the long run we're all dead.
10:52:14PMunchAnti modular?
10:52:49*kier joined #nim
10:53:07PMunchThe idea is to be able to edit and modify something and only realize it into code when you call a finilizer
10:53:49couven92PMunch, can't you just create an compile time object and pass it on...
10:54:41couven92Araq, can you create a const seq that is filled by a compile-time proc?
10:54:56PMunchHmm, I guess that's pretty much the same..
10:55:11Araqcouven92: yes.
10:55:21couven92wow! :O
10:55:46PMunchI basically want init -> do stuff -> finalize with Nim only generating code when finalize is called based on all the stuff you did since init
10:56:35couven92PMunch, create a hidden object somewhere, call new and pass a finalizer that has captured that hidden object
10:57:22PMunchYeah, a compile time global variable. That's what I was asking Araq if was possibl or not :P
10:57:48couven92PMunch, no... in the object you're initializing, just create a private field there
10:58:32PMunchAh, you're saying I should pass around the object
10:58:55couven92just a moment, let me write up an example
11:02:22*Snircle joined #nim
11:05:07Araqit's possible and even easy but it will cause problems for the poor compiler writer in the long run

11:11:26livcdwhat forums / channels people check for nim (besides the official one)
11:12:23PMunchIs any of that code evaluated at compile-time?
11:12:39PMunchlivcd, r/nim
11:12:43PMunchOn reddit
11:12:56PMunchBut I guess that's kinda official
11:16:53PMunchcouven92, let's say I have a compile time sequence of ints. I add a bunch of numbers. Then, when I call finalize (a macro) it sums up all the numbers in the int and creates n counts of echo "Hello, world".
11:17:39PMunchThe only thing that exists in the final code is a lot of echo "Hello world". The sequence and all of the adding and summing stuff was done at compile-time.
11:18:55PMunchBut I think this would work for my case: https://news.ycombinator.com/item?id=9479356
11:19:42couven92hmm...
11:19:50couven92yeah okay
11:21:00PMunchAraq, is this the kind of thing you were saying would cause a lot of trouble?
11:21:40couven92globals can ALWAYS cause trouble! :P
11:22:08PMunchHaha, of course. But except the regular trouble with globas
11:22:11PMunchglobals

13:52:37Araq'nim pretty' or 'nim fmt' ?
13:53:16cremformatter?? ah, that would be great!
13:53:23cremI vote for fmt.
13:54:13Araqmeh if in doubt, use something with a vowel
13:54:26Araqso 'nim pretty' it is
13:55:08cremwhy not format then?
13:55:24*relax joined #nim
13:55:27Araqbecause I long for pretty things.
13:55:54Araqthat's still what tut1 says iirc
13:56:54Araqyeah it does, "Der Mensch ist doch ein Augentier -- schöne Dinge wünsch ich mir."
13:57:05FromGitter<krux02> "nim prty"

13:58:42couven92that's really nice trolling :D
13:58:52couven92Araq, go fmt does
13:59:20Araqoh yeah, I can create a backup file
13:59:33Araqbbl
13:59:41cremFor html/css/js main tool does "pretty", for python/c++/go it's "format", that's from what I know.
13:59:42PMunchHmm, can I have an object with a field of type typedesc? If not, how would I store this information for later use in a macro?
13:59:42*ShalokShalom joined #nim
14:01:48FromGitter<krux02> yes I prefer format, too. Pretty is subjective, formatting is not
14:01:53dom96I think you should use 'format'
14:02:03dom96heh, was about to say what krux02 just did
14:09:36FromGitter<ephja> "prty" should be obvious, and it saves some space!
14:10:31FromGitter<Yardanico> we have "nim c"
14:10:35FromGitter<Yardanico> so add "nim p" :D
14:11:47FromGitter<krux02> or add an engines that tries to identify the closest match of available commands
14:12:42FromGitter<krux02> so "nim froamt" would still be "nim format"

14:24:21FromGitter<krux02> without code, no help
14:24:59FromGitter<Yardanico> if your macro accepts a typedesct
14:25:12FromGitter<Yardanico> it's still implicitly converted to NimNode
14:25:21FromGitter<Yardanico> everything is converted to NimNode if you pass it to macro AFAIK
14:25:33FromGitter<krux02> unless it is static

14:26:53FromGitter<krux02> me too
14:27:55PMunchThe thing I'm trying to do is on compile time take in a variable, check it's type, and store it for later. After a few calls that does this I want to do a final call that looks at the stored information and generates some code from it
14:28:19PMunchs/it's/its
14:28:21FromGitter<krux02> ah
14:28:36FromGitter<krux02> so you need a static block
14:28:46FromGitter<krux02> can you just post the codes
14:29:20*claudiuinberlin joined #nim
14:29:20PMunchhttp://ix.io/AKt
14:29:31PMunchMight be completely misguided though
14:30:24PMunchBut the code at the bottom (in the isMainModule section) is somewhat what I imagine it would look like
14:30:28FromGitter<krux02> you call getType on an ``untyped`` input
14:30:32FromGitter<krux02> that can't work
14:30:45PMunchOh yeah, I've been switching back and forth trying to get it to work
14:31:27PMunchMakes no difference though
14:31:54PMunchPreferably I would do without the getType call at all
14:32:09PMunchBut I don't think compileTime procs can take in AST
14:32:27FromGitter<Yardanico> they can take AST
14:32:32FromGitter<Yardanico> (NimNode arguments)
14:32:54FromGitter<krux02> wtf you have a type in a static block?
14:33:00FromGitter<krux02> how does that make sense?
14:33:15PMunchAs I said, I've just been trying everything
14:33:19PMunchMade no difference
14:33:22FromGitter<krux02> sorry, but I have no idea what the purpose of it is
14:34:27PMunchWhat I'm trying to do is to create a UI specification in the UserInterface object that will, when I call 'finalize', generate code to create some UI
14:35:03PMunchYardanico, but how do I get Nim to convert the argument to a NimNode?
14:35:37PMunchIf I change t in the addWidget call to be of type NimNode it complains that it got an int but expected a NimNode
14:36:06FromGitter<krux02> http://ix.io/AKw
14:36:48FromGitter<krux02> I have no idea what you want, but that is what you said
14:37:00FromGitter<krux02> macros that have a side effect
14:37:06FromGitter<krux02> they add stuff to buffer
14:37:24PMunchHmm, interesting
14:37:26FromGitter<krux02> and then in the end there is baz that does something
14:38:03PMunchOh well, I have to play around with this more when I get home

18:04:02FromGitter<Yardanico> @brentp about mathexpr: maybe https://github.com/sid-code/boolalg is that you need?
18:04:18FromGitter<Grabli66> Is it posible to create async iterator? :)
18:04:20AraqDemos[m]: yeah, that's actually quite a generic task
18:04:33Araq"run program over this snippet"
18:04:46FromGitter<Yardanico> @Grabli66 no, because async proc becomes an iterator itself
18:05:00FromGitter<Yardanico> async is implemented by (ab)using iterators :)
18:05:03Araqgrabli66: yes because async is built on iterators
18:06:26FromGitter<Grabli66> But why i can't use "await" in iterator?
18:07:27FromGitter<brentp> @Yardanico thanks for the pointer. that doesn't seem to support e.g. `>` or `<` either
18:10:00FromGitter<Yardanico> @brentp well my mathexpr is pretty basic. I also have a separated parser/evaluator version, but it's slower (because steps are separated)
18:10:39FromGitter<Yardanico> I should just port tinyexpr to Nim
18:11:06FromGitter<Yardanico> and then refactor it

18:11:58FromGitter<Yardanico> I'm talking about this : https://github.com/codeplea/tinyexpr/
18:13:19dom96Grabli66: yes, use a FutureStream

19:29:12FromGitter<adamrezich> if I make `Foo` an `object` it works, as in, you pass the whole object, but I can't seem to pass the object to the proc in the DLL by pointer nor by `ref`. is this impossible?
19:30:30FromGitter<Yardanico> well I don't really know, maybe you can try passing apointer instead?
19:31:15Araqyou need to compile against "nimrtl.dll" as the docs explain
19:32:01FromGitter<Yardanico> ah, didn't you do that? @adamrezich

19:33:53FromGitter<Yardanico> also, I assume it isn't possible to use async procedures from another dll's ?
19:33:58FromGitter<Yardanico> if they're written in Nim too
19:35:31FromGitter<adamrezich> I missed the nimrtl.dll thing, that forum post mentions it but was also confused by it
19:36:07FromGitter<Yardanico> well I think you should read the docs :)
19:36:08FromGitter<adamrezich> I have a nimrtl.dll in my nim/lib, do I include it with my project then?
19:36:12FromGitter<Yardanico> *firstly
19:36:28FromGitter<Yardanico> https://nim-lang.org/docs/nimc.html#dll-generation
19:36:50FromGitter<Yardanico> if you want to link with it, use nim c -d:useNimRtl myprog.nim
19:37:05FromGitter<Yardanico> and then nimrtl.dll should be accessible from your main executable (or dll, I don't really know)
19:37:11*Demos_ quit (Quit: Demos_)
19:37:26FromGitter<adamrezich> yeah I'm confused by that, I ran that and it failed because it couldn't find nimrtl.dll, because it's in my nim/lib, not in my project directory. so am I supposed to copy it there?
19:37:31*Demos_ joined #nim
19:37:36Araqyes.
19:37:36FromGitter<Yardanico> yes
19:38:00AraqDLLs are always next to the .exe, otherwise they are looked up in the PATH
19:38:46FromGitter<adamrezich> right, I just wasn't sure if I was supposed to include it in my project or if there was some internal way of handling it for me
19:40:12FromGitter<adamrezich> do I need to -d:useNimRtl for the dll too?
19:40:27Araqyes
19:40:54Araqthat's the point, every binary asks nimrtl.dll for memory
19:41:20Araqand so everything goes through the same alloctor
19:42:00FromGitter<adamrezich> sure, makes sense
19:43:31FromGitter<Yardanico> hmm, something interesting here https://github.com/SunDwarf/NimBA :)
19:44:11SunDwarfuh oh
19:44:11FromGitter<adamrezich> if you take that same gist, put nimrtl.dll in the directory, and do ⏎ ⏎ ```nim c -d:useNimRtl --app:lib demo ⏎ nim c -d:useNimRtl -r app``` ⏎ ⏎ it compiles, but still fails to pass the ref object correctly :\ [https://gitter.im/nim-lang/Nim?at=59d53a0bb59d55b8237307f7]

20:54:54FromGitter<mratsim> For Travis CI MacOSX build, any idea which option has the less wait time? (https://blog.travis-ci.com/2017-09-22-macos-update) ⏎ ⏎ > Currently, Travis CI has three types of hosted build environments for open source customers hosted on three different cloud providers: ⏎ ⏎ > sudo: false, container-based (Docker / Ubuntu) hosted on Amazon AWS EC2 ...

20:58:47FromGitter<mratsim> ah I misread >_> I thought they had 3 macOS solutions ...

21:11:50FromGitter<mratsim> @dom96 I don’t see the Nimble tag mentionned anywhere in nimble repo. Missing In Action? https://github.com/yglukhov/nimble-tag
21:12:15dom96Needs to be made smaller first

21:42:26FromGitter<Yardanico> @brentp I was talking about porting it, not creating a wrapper :) I already had tinyexpr wrapper in my mathexpr repo
21:43:14FromGitter<brentp> yeah. I figured. I was just familiar with that lib and need some of the features it has.

21:57:10dom96damn, I'm pretty proud of how I'm solving this CS assignment in Nim
21:57:14dom96Too bad I can't share it :)

22:05:36Demos[m]nim is such a lifesaver when you're like "crap I need to use cpp for this"
22:05:46Demos[m]and you don't want to force everyone to install calypso
22:06:18Demos[m]a calypso like project for nim would be MEGA cool btw
22:06:22Demos[m]it's a ton of work though

22:50:25FromGitter<brentp> anyone know of any examples of packages in nimble that include c code and use `{.compile.}` rather than linking to shared lib?
22:51:58FromGitter<brentp> cant figure out how to get the library that i posted above to install with nimble.
22:53:04FromGitter<zacharycarter> yeah
