05:35:15FromDiscord<ElementalX> Hi, this might be a dumb question to ask, but can something like this be done in Nim? https://blog.finxter.com/daily-python-puzzle-how-to-modify-sequence-while-iterating/ I.e., adding an element to a mutable sequence while iterating also is there any module or function which helps in printing the size of each element in case of the array has 5 strings and each has 4 characters each! Thank you!
05:35:39FromDiscord<Elegantbeef> It can be done just not with Nim's built in iterator
05:36:08FromDiscord<ElementalX> would be great if you could let me know more about it

05:41:33termerwhen working with asynchttpserver and ORC GC, is it common to see huge amounts of memory allocation that never goes away?
05:41:45termerIt doesn't always continue to grow, so I don't know if it can be considered a memory leak
05:41:51termerbut I've noticed this with seemingly all async IO

06:29:47termerwhy does zig cc matter over gcc
06:29:57FromDiscord<Elegantbeef> It has a cross platform linker
06:30:00termerand is it actually its own compiler or does it leverage a different compiler under the hood

07:15:26FromDiscord<Elegantbeef> Is the error inside Orc's procedures?
07:16:38FromDiscord<Elegantbeef> If so it's likely that it uses behaviour that doesnt work well with Orc and it needs to be changed a bit

07:41:35FromDiscord<Elegantbeef> Of course
07:42:17FromDiscord<ElementalX> so its like : am trying these basic exercises which says create an empty array which can hold 10 integers and then fill that array with numbers 10,20,30,40 till 100
07:42:34FromDiscord<Elegantbeef> What does the compiler say?
07:42:59FromDiscord<ElementalX> Error: unhandled exception: index 11 not in 0 .. 9 [IndexDefect]
07:43:24FromDiscord<ElementalX> not sure what other way I could traverse from 0 to 100 and add it to the empty array
07:43:25FromDiscord<ElementalX> 😅
07:43:36FromDiscord<ElementalX> https://narimiran.github.io/nim-basics/#_exercises_3
07:43:37FromDiscord<Elegantbeef> `countUp` exists
07:43:48FromDiscord<ElementalX> yeah tried that too
07:44:00FromDiscord<Elegantbeef> What do you have now?
07:44:28FromDiscord<ElementalX> still the same error I tried `for i in countUp(0,100,10)` the same IndexDefect comes up
07:45:32FromDiscord<Elegantbeef> Well `0` and `100` are inclusive so that's not where the issue is

08:06:07FromDiscord<ynfle> Shouldn't they not be allowed to unless I compile with -d:ssl?
08:06:12FromDiscord<ynfle> https that is
08:06:29FromDiscord<ynfle> Which std lib procs use it?
08:06:48PMunchWell it depends if the library author uses a `when defined(ssl)` switch or if they just assume it's there
08:08:07FromDiscord<ynfle> Is there a way to undefine something?
08:09:23FromDiscord<ringabout> `--undef:ssl`
08:10:23FromDiscord<ynfle> No way...
08:11:37PMunchI'm pretty sure thats only for disabling things enabled by global configuration files
08:12:29PMunchBy the way @ynfle you can grep the Nim sources to get an idea about what uses ssl
08:12:32FromDiscord<ynfle> Does status bearssl load it? How would I checkout?
08:13:04FromDiscord<Elegantbeef> bearssl is statically linked there

08:16:41FromDiscord<Elegantbeef> the highest valid index is `9`
08:16:54FromDiscord<Elegantbeef> `for i in 0..100: a[i] = ..` will index with `10..100`
08:16:59FromDiscord<Elegantbeef> Those are all invalid

11:35:02FromDiscord<dlesnoff> In our file, accidentally all the procs (maybe at a few exceptions) did not use sideEffects.
11:35:27FromDiscord<dlesnoff> (edit) "our" => "the Bigint project"

11:36:46FromDiscord<dlesnoff> I don't understand. func is basically a wrapper of the pragma {.strictEffects.}. What has gone default?

11:46:52FromDiscord<ringabout> (edit) "become" => "becomes the"

12:50:47FromDiscord<ringabout> I don't the solution of that rfc. `legacy:laxeffects` should be useful for transition periods. There seems to be some other bugs for `stricteffects` which cannot be solved with `laxeffects` should be fixed indeed

13:45:50arkanoidmy projects have classic structure: src/ for project, and tests/test_*.nim for tests. I have two problems with this: vscode doesn't work on test files but only on project files, and when I run "nimble tests" it doesn't give me an aggregate view of the different test_*.nim files, but just runs each test_*.nim file separately and stdout is a mix of stuff that doesn't really feel like a test report
13:46:39arkanoiddo you know how can I improve this? I was thinking abount merging all test_*.nim files into test_all.nim and `include` all tests into that one. But this is smelly code, in my opinion
13:48:15FromDiscord<vindaar> keep the distinction in mind that this variant (while I use it a lot out of habit), actually loops twice over 10 elements. The `collect` one is a single loop (but has the downside of currently starting from a seq without explicit size, thus may lead to multiple reallocations, depending on use case)↵(@dlesnoff)
13:49:12FromDiscord<dlesnoff> In reply to @arkanoid "do you know how": Maybe you can make a new nimble task instead, that parse stdout, collect each timing/test results and outputs them nicely in a table or so.
13:49:38FromDiscord<vindaar> you don't need to use `include`. A simple `import` is fine. All top level code will still run↵(<@709044657232936960_arkanoid=5b=49=52=43=5d>)
13:50:47FromDiscord<dlesnoff> In reply to @vindaar "keep the distinction in": But this uses std/sugar, which makes compile time and running time much slower (at least for the few small programs I tested this on).
13:51:51FromDiscord<dlesnoff> (edit) "In reply to @vindaar "keep the distinction in": ... But`collect`" added "Indeed!" | "this" => "`collect`"
13:51:58*vsantana quit (Ping timeout: 260 seconds)
13:52:37FromDiscord<vindaar> run time should only depend on what I just mentioned. Whether two loops with preallocated memory is faster vs one loop with reallocations will be use case dependent. `std/sugar` shouldn't really be that expensive to import though
13:56:52FromDiscord<pietroppeter> for the collect version you can use `collect(newSeqOfCap(10)):` to make sure memory is allocated correctly during sequence initialization. runtime performance wise I think it should be the same as the array (you will not get compile checks on indices in later usages).
13:57:21FromDiscord<pietroppeter> (and you cannot put it anymore in a single line)
13:57:35FromDiscord<dlesnoff> I am testing both versions on my machine
14:00:54FromDiscord<huantian> In reply to @arkanoid "do you know how": You might also want to think about using a different testing framework like balls which will give you a nice output
14:01:42arkanoidvindaar: thanks, I'm trying the single test_project.nim with all the imports
14:02:05arkanoiddlesnoff, wow, no thanks, don't want to re-create the wheel for tests
14:02:30arkanoidhuantian: thanks! didn't know about alternative test frameworks. I only know unittest and testament
14:05:48FromDiscord<dlesnoff> @Arkanoid Sorry for the very bad proposition. There are other tests framework: https://github.com/ringabout/awesome-nim#testing
14:06:24arkanoiddlesnoff, no problem! It was not really a bad proposition, just an admission of my lazyness :P
14:06:34FromDiscord<dlesnoff> But you can have a look in the #nimble channel where we discussed about testing framework
14:06:59arkanoidvindaar: it works! I have many "imported and not used" in my test_all.nim, but I get a much faster and nicer output
14:07:29arkanoidI've also solved the vscode issue by adding src/myproject.nim and tests/test_all.nim as projects in my settings.json
14:07:33arkanoidall good! thanks
14:08:43FromDiscord<dlesnoff> In reply to @arkanoid "<@150345911057252352>: it works! I": since these are hints, you may try --hints:off or something more selective
14:10:16arkanoidI like hints and I generally want to keep them on. Is it possible to turn them off for test_all.nim only?
14:11:03FromDiscord<vindaar> ah, thanks! Had forgotten about that, as I hardly ever use `collect`↵(@pietroppeter)
14:11:34FromDiscord<dlesnoff> --hints:on|off|list. `on|off` enables or disables hints.↵ `list` reports which hints are selected.
14:12:00arkanoiddlesnoff, I want them all for all files, except one
14:12:03FromDiscord<dlesnoff> --hint:X:on|off turn specific hint X on|off. `hint:X` means `hint:X:on`,↵ as with similar flags. `all` is the set of all hints↵ (only `all:off` is supported).
14:12:41FromDiscord<dlesnoff> I don't know what is X for "imported and not used"
14:14:24arkanoiddlesnoff, it's UnusedImport, I have it as "warningAsError"
14:14:54arkanoidwell, I used to have it, but it gives error in system.nim
14:15:47FromDiscord<dlesnoff> In reply to @arkanoid "<@610977647601909781>, I want them": maybe you can add a .cfg with an if clause and something to get your module filename but I don't find how to get the name of the module you are compiling
14:16:07FromDiscord<dlesnoff> (edit) ".cfg" => "nim.cfg"
14:19:17FromDiscord<! Nilts> Does anyone know a storage option like json except focused on less memory use?
14:19:28FromDiscord<! Nilts> and if i can use it in nim?
14:20:50*vicecea joined #nim
14:21:10PMunchprotobuf?
14:22:12FromDiscord<dlesnoff> @! Nilts There are many serialization options, see e.g. at the end of https://youtu.be/aKg5PxUi_eA?t=2102

14:22:49FromDiscord<Rika> protobuf is more an on the wire protocol though
14:23:09PMunchSure, but you can just dump the output to a file if you'd like
14:23:17PMunchOpenStreetMap stores data this way
14:23:46PMunchWell, they also have XML. But if you don't want to download a massive file then the protobuf format is the way to go
14:27:04ehmryNilts there is also CBOR and Preserves, which are self describing formats
14:27:17FromDiscord<dlesnoff> In reply to @Jiezron "maybe you can add": @Arkanoid Sorry I checked and actually you can't be certain of the module name you are compiling, since the name of os.getAppFilename will actually give you the name of the generated C(++)/obj/js file you compile to.
14:27:20FromDiscord<pietroppeter> In reply to @arkanoid "<@610977647601909781>, I want them": I think a pragma {.push hints:off.} at the top of your test file should work, example: https://github.com/bluenote10/NimData/blob/d8b0d9744c3960fd75966e2b71ecc8557a8e31ee/tests/all.nim

14:47:02FromDiscord<dlesnoff> In reply to @ElementalX "hey <@610977647601909781> ,": Rather than saying that your program does not work, please precise whether you run into an error during compilation or during execution, or whether you got an incorrect output.↵(Even though I could test snippets in my editor).
14:48:30FromDiscord<ElementalX> sure, I would do that, thank you!
14:48:35PMunchHmm, maybe I should auto-import a `module` macro in the playground. So that people can write `module mymodule: echo "Hello world"` and all it does is write the contents to a file by that name with the .nim extension so it can be loaded by the main module
14:53:46FromDiscord<pietroppeter> or write a package with this module macro inside and add it as available packages in playground 🙂 (so people can use it even outside the playground)

15:03:20arkanoidI like having problem list clean of hints and warning, but I get some from stdlib. For example times.nim "'parse' cannot raise 'Defect' [XCannotRaiseY]".

15:09:21PMunch@Jessa,
15:09:29PMunchhttp://ix.io/4fdW
15:09:31PMunchThat works
15:10:37FromDiscord<pietroppeter> In reply to @PMunch "<@869267093110026320>, sure, that shouldn't": I guess it should be something more sophisticated than this, then (does not work on playrgound nor locally): https://play.nim-lang.org/#ix=4fdV
15:11:40PMunchA couple of things you missed, exportc/dynlib to make sure the symbol is exported correctly (no name mangling). Type signatures need to match exactly, having var in one definition and not in the other causes issues becaues it informs Nim how it is supposed to pass the data. And when doing things with dynamic libraries it is best to use ARC/ORC otherwise you'll need to link to the garbage collector as a separate library from both modules
15:11:50PMunchAt least I think ORC/ARC should work without requiring that..
15:12:32FromDiscord<Jessa> I see
15:14:06PMunch@pietroppeter, https://play.nim-lang.org/#ix=4fdX

15:16:28FromDiscord<Bung> ok, I see
15:16:29PMunch@Jessa, ah if you used those then it was probably just the var missing which tripped you up
15:16:53PMunchEssentially that makes Nim pass a pointer to the variable on the caller stack so it can be modified in-place
15:17:25FromDiscord<pietroppeter> In reply to @PMunch "That works fine": ah nice, indeed my snippet locally does not work when using `nim r` but works with `nim c -r` (which I guess makes sense since nim r uses a temp folder)
15:17:29PMunchAnd ORC/ARC are the new memory management schemes that will become default in Nim 2.0
15:17:57FromDiscord<Jessa> In reply to @PMunch "<@268111216277323779>, ah if you": Cool! ↵good to know, don't think i'll miss that next time now :P

17:52:33PMunchThe fuck.. Copied some C code from a pdf and converted it to Nim. Apparently it used en-dashes instead of minuses..
17:56:28FromDiscord<dlesnoff> Try to copy a code from a pdf is hell, especially on linux. It depends heavily on the backend of your viewer like mupdf or poppler.
17:57:09FromDiscord<dlesnoff> (edit) "Try to copy" => "Copying" | "hell," => "deceptive,"

18:06:50FromDiscord<dlesnoff> In reply to @PMunch "The fuck.. Copied some": You can always apply some sed to change all en-dash to minuses
18:06:54FromDiscord<auxym> I have used this in the past to extract data tables from PDFs, worked great. Not sure how it would do with code? https://tabula.technology/
18:07:02PMunchYeah, that's what I did

18:19:45FromDiscord<dachian> Is it possible to incorporate Nim's compiled C code into a foreign language's cffi?
18:21:22FromDiscord<Elegantbeef> What do you mean?
18:21:32FromDiscord<Elegantbeef> Can you make libraries using Nim?
18:22:49FromDiscord<dachian> So for example Dart and python have cffis which allow you to call c functions and wrap them with a dart or python interface
18:23:06FromDiscord<Elegantbeef> Yes you can expose Nim code as a system library
18:23:14FromDiscord<Elegantbeef> `--app:lib` and `exportC`
18:23:41FromDiscord<dachian> oh cool thx let me try that real quick and get back
18:24:13FromDiscord<Elegantbeef> Pixie for instance is accessible from python and C using genny

18:25:59FromDiscord<dachian> In reply to @Elegantbeef "Pixie for instance is": so is it better practice to use genny or --app:lib exportC
18:26:15FromDiscord<dachian> or do u use genny in combination with the above
18:26:36FromDiscord<Elegantbeef> Well without genny you have to manually make type definitions
18:26:50FromDiscord<auxym> genny basically automates the exportC process / makes it easier to use
18:27:01FromDiscord<auxym> so your choice if you want to do it manually or let genny do it for you
18:27:14FromDiscord<Elegantbeef> You still need `--app:lib` or `--app:staticlib` depending on what you're after
18:29:26termerORC GC seems to cause so many problems
18:29:34termerhttpbeast is broken with it
18:29:51termerand I've been having issues with db_sqlite with it
18:30:11termerit looks like my database instance is getting GC'd even though it's top level and never goes away
18:30:22termerthis happens when working with async code
18:30:44FromDiscord<Elegantbeef> Do you have any threading?
18:30:55termerin my sqlite test, no
18:31:05termerhttpbeast has threading
18:31:15termerare there best practices for threading with orc
18:31:37termerI've had some memory-leaking code possibly related to either sqlite or the way I'm doing threading in another project
18:32:01FromDiscord<Elegantbeef> I cant really say more than i did yesterday, i dont use threading or async
18:32:18termerguess my memory is poor
18:32:59FromDiscord<Elegantbeef> When using global heap allocated memory you will likely need to use `{.cast(gcSafe).}:` and `let myVar {.cursor.} = myCollection[ind]`
18:33:21termerwhat is the behavior of gcSafe and cursor
18:33:24termerI've seen gcSafe before
18:33:26termernot cursor though
18:33:35FromDiscord<Elegantbeef> Or using the `threading` module
18:34:00FromDiscord<Elegantbeef> cursor creates an unowned reference, which means the ref counter isnt touched when destroyed
18:34:21FromDiscord<Elegantbeef> https://github.com/nim-lang/threading is likely the best threading experience for orc
18:34:33termerjust pulled that up when searching
18:34:41termerdoes it have pre-generated docs or do I need to run nimdoc
18:35:00FromDiscord<Elegantbeef> There are 3 modules
18:35:26termerI'll take a look at it then
18:35:30FromDiscord<Elegantbeef> It's like \< 1000 loc with doc comments
18:35:55termerthe memory leaks and crashes under orc have been driving me crazy so hopefully this helps
18:36:21termerthe alternative to threading is just running single-threaded, and at that point I'd just use nodejs
18:36:26FromDiscord<Elegantbeef> It's likely just you're accidently sharing ownership of resources which causes deallocation
18:36:41FromDiscord<Elegantbeef> The segfaults come from orc's procedures eh?
18:36:54termerusually a use a pointer to a channel which was made with createShared
18:37:04termerthat's how I do cross-thread communication
18:37:08termeror queue
18:37:11termernot channel
18:37:20termersame concept though
18:38:48FromDiscord<Elegantbeef> Yea channels are nice
18:38:48FromDiscord<Elegantbeef> Will be nicer soon with isolated

18:39:24termerI need to look through the code and see which I used

18:43:17FromDiscord<Horizon [She/Her]> But thanks!
18:43:43FromDiscord<Elegantbeef> The channels are global and dont have any heap allocated portion
18:43:55termernow that's sweet
18:44:08FromDiscord<Elegantbeef> Well Nim managed heap allocation
18:44:23FromDiscord<Elegantbeef> You can do the same with the present channels
18:44:55FromDiscord<Elegantbeef> You only need to pass a `ptr Channel` if you want each thread to have it's own channel
18:45:14termerusually I just use channels for passing work to/from a worker thread
18:45:18termerlike in the case of sqlite
18:45:27termerI need to perform queries without blocking an HTTP thread
18:45:32FromDiscord<Elegantbeef> So then a global channel could work
18:45:40termerit should
18:46:10termerwhen you have a single thread to do a type of work then it would work perfectly I'd imagine
18:46:39termerand assuming locks are working right, there should be no problem expanding the number of workers
18:50:10FromDiscord<auxym> I really hope this whole threading/channels situation gets way better in 2.0. Sounds like sort of a mess atm
18:50:19termerit's terrible
18:50:26termerif you throw async into the mix it becomes a nightmare
18:50:47FromDiscord<Elegantbeef> I honestly dont know what's wrong with channels 😄
18:50:55FromDiscord<Elegantbeef> I've used them before and it worked just fine
18:51:03termernothing's wrong except there are magical things that make memory do funny things in orc
18:51:08termerand cause crashes if you're not careful
18:51:17FromDiscord<Elegantbeef> isolated should make channels 0 cost even in orc
18:51:33termerI'll have to check things out and make sure they're working right
18:52:12FromDiscord<auxym> never really needed/used them. But as I understand we have two channels implementations? The stdlib and threading? And threading isn't documented? And sometimes you have to use ptr Channel, for reasons? And all of this is poorly documented?
18:52:38FromDiscord<Elegantbeef> It's not for reasons
18:53:11FromDiscord<Elegantbeef> You need `ptr Channel` if you want to pass a specific channel to a thread, it's that simple
18:53:32FromDiscord<Elegantbeef> Threading is the future of Nim's threading and is still under development, it is documented though
18:53:40*PMunch joined #nim
18:53:42FromDiscord<auxym> In what other case would you ever want a channel, other than passing it to a thread?
18:53:58FromDiscord<Elegantbeef> When you have a global channel that's used as a queue for worker threads
18:54:24FromDiscord<Elegantbeef> You dont need to pass a channel anywhere, you just access the channel directly in that case
18:54:35FromDiscord<auxym> don't you still have to pass a ref/ptr to the channel to each thread though?
18:54:36FromDiscord<auxym> Oh
18:55:07FromDiscord<Elegantbeef> Channels are stack allocated types(well the data is heap allocated but it's managed by the thread)
18:55:18termerPMunch I watched your talks on running Nim on microcontrollers
18:55:26FromDiscord<auxym> Still, in general the idiomatic nim way is to never use ptr, so having to use ptr for channels as the standard use case feels sort of weird
18:55:35termerthose were very eye-opening, since I was convinced nim wasn't suitable for devices like that
18:55:39FromDiscord<Elegantbeef> managed by the channel\
18:55:58FromDiscord<Elegantbeef> I mean we're talking about threading
18:55:59FromDiscord<Elegantbeef> If you get stuck on pointers while you're attempting to thread i'm a bit scared of your generated threaded code
18:56:07FromDiscord<auxym> Anyways, ty for the info. I should try out threading sometime. Good news if threading is under active development and gets better in the future
18:56:46FromDiscord<Elegantbeef> With orc/arc you might(I dont know if this is true) be able to pass `ref Channel`
18:57:11FromDiscord<Elegantbeef> Eh that seems unlikely though
18:57:17FromDiscord<auxym> In reply to @Elegantbeef "If you get stuck": my only experience with threads TBH is python, and you don't need to know anyhting about pointers. A thread-safe Queue is provided as a high-level sync primitive which takes care of most things without fuss
18:57:50FromDiscord<Elegantbeef> Something about python's evaluator being single threaded here
18:58:01FromDiscord<auxym> yes, yes, GIL, etc 🙂
18:58:20FromDiscord<Elegantbeef> When you dont have code running at the same time it's a bit easier to manage
18:59:01FromDiscord<Elegantbeef> Nim threading has you dealing with code running at the same time so it requires some thought into what you're doing, mainly with regard to memory management
18:59:04FromDiscord<auxym> from my understanding, python Queues would still be thread-safe in the absence of the GIL. They are synchronized by OS-level locks/condition vars, under the hood
18:59:08FromDiscord<Elegantbeef> It's extremely easy to have race conditions with memory management
18:59:19FromDiscord<Elegantbeef> Sure and channels are threadsafe

18:59:41FromDiscord<auxym> yes but pointers 😠
18:59:48termeryou only really have to use the proper thread-safe List implementations and the `synchronized` keyword
19:00:02FromDiscord<auxym> In reply to @termer "any of my threading": yeah. exactly.
19:00:54*jkl joined #nim
19:01:26FromDiscord<Elegantbeef> Meh pointers arent that scary
19:01:45FromDiscord<auxym> I know, just doesn't feel like very idiomatic Nim
19:02:20FromDiscord<auxym> Nowhere else in the stdlib is the "normal" way to things requires ptr (other than c ffi obviously)
19:02:21FromDiscord<haywireSSC> how would I iterate through file names in a directory in compile time? would I need to use staticExec and ls command?
19:02:30termerpointers aren't scary
19:02:34termerGC with pointers is scary
19:02:44Amun-RahaywireSSC: that, tbh, makes little sense
19:02:54Amun-RahaywireSSC: unless directory contents are fixed
19:03:36FromDiscord<Elegantbeef> You can do `import std/os` and `walkFiles` assuming your target OS supports `std/os`
19:03:57FromDiscord<haywireSSC> In reply to @Elegantbeef "You can do `import": do most things like that also work in compile time?

19:08:30FromDiscord<ezquerra> Would it be as (or perhaps more) efficient one way or the other??

20:55:05FromDiscord<Phil> So far the lazyness has won
20:56:04FromDiscord<ShalokShalom> See it as a contribution
20:56:22FromDiscord<Elegantbeef> Yea not all of them↵(@haywireSSC)
20:56:35FromDiscord<Elegantbeef> It's not for `static` evaluated code↵(@auxym)
20:56:54FromDiscord<ShalokShalom> Its doesnt really matter, if you buy the book or contribute the money ↵↵The book costs are minimal, the income for Andreas/the project will be similar
20:57:10FromDiscord<ShalokShalom> @Phil
20:57:19FromDiscord<Elegantbeef> Book probably gives more than patreon
20:57:38FromDiscord<Elegantbeef> Patreon takes a larger cut than publishers/printers likely but idk
20:58:18FromDiscord<Phil> Something in my brain refuses the double dip
20:58:35FromDiscord<Phil> So its a matter of lazyness
21:00:38FromDiscord<ShalokShalom> In reply to @Elegantbeef "Patreon takes a larger": Ah, yeah true. Forgot that Patreon even takes something.
21:00:58FromDiscord<ShalokShalom> And with buying the book, you show interest in the language too
21:01:11FromDiscord<ShalokShalom> Andreas can then say, xx people bought my book.
21:05:03FromDiscord<haywireSSC> In reply to @Elegantbeef "Yea not all of": do you think I would need to run commands to list files and iterate over their output insted?

21:08:33FromDiscord<Slazaa> Here I'd like the first echo to get me Derived basically
21:08:37FromDiscord<Elegantbeef> `Derived(ob)`
21:08:52FromDiscord<Elegantbeef> `proc showType[T: Base](obj: T)`
21:09:07FromDiscord<Slazaa> Oh ok :o
21:09:22FromDiscord<Elegantbeef> Nim's `type`(really you should be using `typeof`) is static and does not know about runtime
21:09:27FromDiscord<Slazaa> Yeah it works thank you :3
21:09:58FromDiscord<Elegantbeef> the above makes the procedure generic and constrains to all subtypes of `Base`, so when you call it with a subtype it generates a new procedure specifically for that
21:10:32FromDiscord<Slazaa> And why does the condition is true though ?
21:10:33FromDiscord<ShalokShalom> Why typeof instead type?

21:10:48FromDiscord<Elegantbeef> sent a code paste, see https://paste.rs/ogN
21:10:49FromDiscord<Elegantbeef> cause `of` is runtime
21:10:54FromDiscord<Slazaa> :o
21:11:18FromDiscord<ShalokShalom> Runtime, as in dynamic typing?
21:11:21FromDiscord<Elegantbeef> Cause `typeof` is supposed to be used in typing expressions as it's more clear and doesnt overload a existing word, and it can take parameters

21:11:43FromDiscord<ShalokShalom> Ah

21:13:14FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4ffq
21:13:34FromDiscord<Elegantbeef> Nim does not really have mechanisms to get the name of a type at runtime, without bodging around

21:31:34FromDiscord<geekrelief> yeah the provided examples should work and has worked fine
21:31:51FromDiscord<geekrelief> @jmgomez and I came across this issue while working on NimForUE
21:32:06FromDiscord<Elegantbeef> What's the procedure calling the stringification that is bugging?
21:32:07FromDiscord<Elegantbeef> Is it a generic?
21:32:07FromDiscord<geekrelief> there's been a bunch of commits between when it was working to where it's now broken
21:32:43FromDiscord<geekrelief> we're just calling `$` directly on a type
21:33:07FromDiscord<geekrelief> let me get a code sample for context
21:33:14FromDiscord<Elegantbeef> Not inside any procedure, just at top level?
21:33:22FromDiscord<geekrelief> it's inside a procedure
21:33:33FromDiscord<Elegantbeef> Are you sure the `$` is in scope of the calling procedure?
21:34:02FromDiscord<geekrelief> yeah, I can call the `$` on the type directly, but if the type is in a `seq` it doesn't call it
21:34:17FromDiscord<geekrelief> I have no idea what's causing it to break
21:34:41FromDiscord<geekrelief> https://github.com/jmgomez/NimForUE/blob/d8c307e94be4bdf3beda0edec7287be9ab92c0e7/src/nimforue/examples/examplescodegen.nim#L225
21:35:19FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4ffw
21:35:24FromDiscord<geekrelief> we're just calling it here and writing the output to a file, if I drill into `ueProject`...
21:35:39FromDiscord<geekrelief> sent a code paste, see https://play.nim-lang.org/#ix=4ffx
21:36:02FromDiscord<Elegantbeef> Oh that's not a generic so that mixin wont do
21:36:34FromDiscord<geekrelief> I have a macro generating the `$` procs
21:36:55FromDiscord<geekrelief> https://github.com/jmgomez/NimForUE/blob/master/src/nimforue/macros/makestrproc.nim this was working fine before
21:37:08FromDiscord<geekrelief> something else around it changed and broke it
21:37:14*jmdaemon joined #nim
21:37:38FromDiscord<Elegantbeef> What's wrong with Nim's `$` you dont like that it lacks type name?
21:37:52FromDiscord<Elegantbeef> or you dislike that it does `"..."` for pointers?
21:37:54FromDiscord<geekrelief> sent a code paste, see https://play.nim-lang.org/#ix=4ffy
21:38:05FromDiscord<geekrelief> yeah we need the type name because we're writing the output to a nim file
21:38:17FromDiscord<geekrelief> it gets processed to produce C++ bindings
21:38:43FromDiscord<Elegantbeef> So why not just do `strformat` `{typeof(V)}{$v}` ?
21:39:20FromDiscord<geekrelief> does that work recursively?
21:39:29FromDiscord<geekrelief> I guess I can try it
21:39:32FromDiscord<Elegantbeef> As long as there isnt a pointer
21:39:34FromDiscord<geekrelief> yeah I didn't think of it
21:40:04FromDiscord<geekrelief> but the question still is why would the type in a seq break?
21:40:29FromDiscord<Elegantbeef> Can only imagine the issue is generic binding
21:40:59FromDiscord<Elegantbeef> Inside your `makeStrProc` perhaps a `mixin` would resolve this
21:41:06FromDiscord<geekrelief> can you elaborate on what is generic binding?
21:41:30FromDiscord<Elegantbeef> Generic procedures bind symbols open or closed depending on overloads in context
21:42:07FromDiscord<Elegantbeef> Your `ueProject`'s `$` is likely calling `$` for `seq[T]` and cause it doesnt mixin `$` it's only searching for procedures in it's original scope
21:42:10FromDiscord<Elegantbeef> So your overloads are not found
21:42:28FromDiscord<Elegantbeef> A forward declaration may also help
21:42:40FromDiscord<Elegantbeef> It's quite hard to say with your macros
21:42:55FromDiscord<geekrelief> ok, I'll look into mixin, thanks for the suggestions!
21:43:29FromDiscord<Elegantbeef> You may want to just look into templates and disruptek's assume for easing headaches
21:43:50FromDiscord<Elegantbeef> He has a `typeit` macro that allows iterating fields of a type regardless if it's a object variant
21:44:22FromDiscord<geekrelief> In reply to @Elegantbeef "You may want to": thanks I'll take a look if `mixin` fails to do the trick
21:46:38FromDiscord<geekrelief> sent a code paste, see https://play.nim-lang.org/#ix=4ffA
21:47:04FromDiscord<Elegantbeef> Sounds like a nice fun program
21:47:48FromDiscord<geekrelief> lol
21:50:39FromDiscord<Elegantbeef> Looking at what your `$` does i'm fairly certain you can replace it with much simpler macro-less operators
21:51:13FromDiscord<Elegantbeef> The objects you use `makeStrProc` for are not complex types(well one has an object variant, but nim works with `$` on object variants)
21:58:14FromDiscord<geekrelief> In reply to @Elegantbeef "The objects you use": yeah, right I'm trying this:
21:58:45FromDiscord<geekrelief> sent a code paste, see https://play.nim-lang.org/#ix=4ffG
21:58:55FromDiscord<geekrelief> but getting an ambiguous `$` error for object or T

22:02:40FromDiscord<Elegantbeef> `makeStrProc(T: typedesc)` is proper 😄
22:03:27FromDiscord<Elegantbeef> Even though the type is named specifically it's the same specificity as `object or tuple` it seems
22:03:48FromDiscord<Elegantbeef> Possible RFC or PR there, but typechecker changes are scary

22:08:02FromDiscord<geekrelief> yeah the makestrproc is being imported
22:09:32FromDiscord<geekrelief> it was working before, and after a bunch of commits it broke. I've been staring at the between the commits, and I don't have a clue what could have broken it. I'm considering just giving the string proc a different name just to work around this, but I want to figure out what's going wrong.
22:09:47FromDiscord<geekrelief> missed a word.. staring at the diff
22:10:30FromDiscord<Elegantbeef> https://wandbox.org/permlink/IbD4hN2Ag3w4rANY i dont know what to say
22:10:46FromDiscord<geekrelief> not to throw any shade, but I didn't write the following commits that led to the breakage 😄
22:10:49FromDiscord<Elegantbeef> It seems you have somewhere where the system `$` is being considered above the one provided
22:10:57FromDiscord<geekrelief> I'm just trying to fix it
22:11:01FromDiscord<Elegantbeef> Well i'll blame whoever used `astGenRepr`
22:11:13FromDiscord<geekrelief> ha
22:13:55FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=4ffO
22:14:38FromDiscord<Elegantbeef> It shouldnt be needed but it really seems like system's `$` is being preferred
22:17:08FromDiscord<geekrelief> right, for some reason system's `$` is being called
22:17:45FromDiscord<geekrelief> if I call `$` on the type directly it works
22:18:10FromDiscord<geekrelief> but for seq[T] where T is my custom type it doesn't call my `$`
22:19:15FromDiscord<Elegantbeef> Wait dollars procs do not mixin `$`...
22:20:09FromDiscord<geekrelief> Well it was working before, but now it's not working.
22:20:28FromDiscord<Elegantbeef> Have you updated your Nim compiler?
22:20:29FromDiscord<geekrelief> I'm defining `$` for seqs
22:20:38FromDiscord<geekrelief> I'm on v1.6.8
22:21:02FromDiscord<geekrelief> I ran into an issue on devel.
22:21:23FromDiscord<Elegantbeef> Where do you define `$`?
22:21:43FromDiscord<geekrelief> in a module called `makeStrProc.nim`
22:22:29FromDiscord<geekrelief> it's being imported before it's used in https://github.com/jmgomez/NimForUE/blob/d8c307e94be4bdf3beda0edec7287be9ab92c0e7/src/nimforue/examples/examplescodegen.nim#L5
22:22:46FromDiscord<Elegantbeef> I dont see you defining `$` for seqs in there
22:22:58FromDiscord<geekrelief> right, I'm not
22:23:11FromDiscord<geekrelief> I didn't before and it was working for seqs
22:23:16FromDiscord<Elegantbeef> Well where are you defining it for seqs
22:24:03FromDiscord<geekrelief> I'm not defining it for seqs, it was working before. Just like your wandbox example.
22:24:24FromDiscord<Elegantbeef> Ok well you said twice you were so 😄
22:24:25FromDiscord<geekrelief> But something is breaking it now.
22:24:35FromDiscord<geekrelief> oh I didn't sorry..
22:24:38FromDiscord<geekrelief> (edit) "didn't" => "did"
22:24:46FromDiscord<geekrelief> I probably need to get some sleep.
