00:10:41FromDiscord<Patitotective> is there a way i could validate if a string is valid as an identifier? or should i use regex `IDENTIFIER ::= letter ( ['_'] (letter | digit) )`?

00:46:01FromDiscord<Elegantbeef> So first big thing is you dont need to use cast
00:46:07FromDiscord<Elegantbeef> you can do ` let r = ^FlowVar[seq[seq[int]]](futures[futIdx])`
00:46:25FromDiscord<Zoom> Ah, I always forget about conversions...
00:46:39FromDiscord<Elegantbeef> Secondly this is an orc bug indeed

00:54:27FromDiscord<Elegantbeef> I think it's something to do with the destructors and gc reference

00:59:49FromDiscord<Elegantbeef> Well i'll shoot you a message if i figure out the high level culprit

01:54:57FromDiscord<Elegantbeef> You should pass in your font data, which you probably generated with a procedure call before

01:56:24FromDiscord<Elegantbeef> You dont use FromFile

04:22:08FromDiscord<TryAngle> is there a difference between 1.0f and 1.0 ?
04:22:35FromDiscord<Yardanico> yes, but actually no
04:22:41FromDiscord<Yardanico> ah right, it's just a "yes"
04:22:45FromDiscord<Yardanico> @TryAngle `f` is float 32

04:23:16FromDiscord<TryAngle> In reply to @Yardanico "<@!147447489316913152> `f` is float": ah ok, so if I work with graphical things I should use f postfix right ?
04:23:23FromDiscord<Yardanico> idk, it depends on the type
04:23:31FromDiscord<Yardanico> for float32 you use f, for float64 and float you use `'d`
04:23:41FromDiscord<Yardanico> or just do "123.0", Nim defaults to 64-bit float
04:23:46FromDiscord<TryAngle> or wait, when I put them in functions, nim choses correct type anywyas right ?
04:35:44FromDiscord<xflywind> Hello @PMunch do you have some testcase for futhark regarding https://github.com/nim-lang/Nim/issues/18986 ? I want to verify whether my fix work for futhark too.

05:13:09FromDiscord<huantian> `type Radian = distinct float` boom
05:14:25FromDiscord<j-james> i may just go with `type Radian = float` for convenience
05:14:44FromDiscord<Elegantbeef> Eh
05:14:45FromDiscord<Elegantbeef> What's the point of an alias for radian
05:15:49FromDiscord<j-james> fair tbh
05:16:04FromDiscord<Elegantbeef> Use a distinct or just use a float
05:16:07FromDiscord<j-james> you're usually going to be multiplying them by things that are not radians anyway
05:27:21FromDiscord<Elegantbeef> So make `(radian, float)` and `(float, radian)`
06:03:21FromDiscord<morgan> if i have a tree structure, and i want to have a ref stored that points up the tree, how would i go about assigning that in a proc that adds a new node to the tree?
06:03:33FromDiscord<morgan> would it be `addr`?
06:04:09FromDiscord<Elegantbeef> You use `ref` and then just grab it
06:04:42FromDiscord<morgan> `Error: type mismatch: got 'Command' for 'com' but expected 'ref Command'`
06:04:52FromDiscord<morgan> `parent: com`
06:04:59FromDiscord<Elegantbeef> What's your type?
06:05:14FromDiscord<morgan> https://media.discordapp.net/attachments/371759389889003532/961144533230452806/unknown.png
06:05:18FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3Ur5
06:05:40FromDiscord<morgan> so i should make the object a ref object
06:05:48FromDiscord<Elegantbeef> Probably
06:06:33FromDiscord<Elegantbeef> you could do `ptr Command` and `myCommand.addr`, but generally for this type of stuff you want `ref`
06:07:34FromDiscord<morgan> yeah
06:07:54FromDiscord<morgan> it works with it switched over to a ref object and the ref on the parent var removed
06:11:08FromDiscord<Elegantbeef> Remember `ref` can be `nil` so if you have any uninitialised it'll be nil
06:12:13FromDiscord<morgan> yeah i have one of the new procs initing that with nil

06:17:55FromDiscord<aph> In reply to @Tanguy "Yes you need to": yeah that resolved it, thanks
06:18:10FromDiscord<Elegantbeef> You also can just do `T: Deforms`
06:18:54FromDiscord<aph> In reply to @Elegantbeef "You also can just": heh, i was doing some weird reassign thing. i tried `var Variable: Deforms = Bdef1()` but it didn't work lo
06:18:55FromDiscord<aph> (edit) "lo" => "lo;"
06:19:01FromDiscord<aph> (edit) "lo;" => "lol"
06:19:04FromDiscord<Elegantbeef> If course not
06:19:26FromDiscord<Elegantbeef> They're `object` not `ref object` they're stack allocated as such cannot be converted between types
06:19:46FromDiscord<Elegantbeef> If you want them to abide by inheritance use `ref object` and then you can
06:19:47FromDiscord<aph> ohh
06:20:37FromDiscord<Elegantbeef> You can only safely convert to `var T` without losing fields, any other conversion copies and loses fields
06:21:42FromDiscord<aph> yes i'm doing that in my code :)
06:21:59FromDiscord<Elegantbeef> It looks like you want `ref object`
06:22:13FromDiscord<Elegantbeef> If you want to be able to assign any `of Deform` to the field
06:22:55FromDiscord<aph> `ref object` in `Deforms`?
06:23:05FromDiscord<Elegantbeef> For all of them
06:23:12FromDiscord<Elegantbeef> all of your inherit objects
06:23:14FromDiscord<aph> ohh

06:27:48FromDiscord<aph> wow
06:43:43FromDiscord<bryankrn> as someone whos never used operator overloading, nim's operator overloding is cool as hell
06:44:58FromDiscord<Elegantbeef> Yea it's done in a really swell way
06:47:06FromDiscord<Phil> I've used it in Java and used it like there, is there a significant difference?
06:47:29FromDiscord<Elegantbeef> In nim it's very simple and you can have user defined operators

06:48:04FromDiscord<Elegantbeef> No fancy keywords, just easy and sensible
06:48:46FromDiscord<Phil> Also to be on the safe side : I am correct in assuming that generic procs don't play very nicely with overloading, correct?
06:48:56FromDiscord<Elegantbeef> They do
06:49:10FromDiscord<Elegantbeef> specialzed is taken over generic
06:49:28*PMunch joined #nim
06:50:37FromDiscord<Phil> The scenarios I had were 2 generic procs with the same name but different arguments, I don't recall having used a specialized proc in there anywhere but it's possible I overlooked something
06:50:47FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3Ure
06:51:56FromDiscord<Elegantbeef> different arguements how?
06:55:09FromDiscord<Phil> Sorry, different params. They were both called "createHandler" and the second one called the first. First took 4 parameter, second one took 2 parameters and called the first with those 2 and 2 default params.
06:55:34FromDiscord<Elegantbeef> So what's the issue they're overloadable
06:55:40FromDiscord<Phil> Everything involved in what I just described was a generic proc, even the handler.
06:56:28FromDiscord<Phil> It kept trying to use the 2 Param one even when I specified 4 params iirc. I'll play around with that again after work
06:56:43FromDiscord<Elegantbeef> Nim also has name overloading
06:57:02FromDiscord<Phil> (edit) "handler." => "parameters."
06:57:16FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#ix=3Urg
06:57:33FromDiscord<Phil> Holy shit
06:58:18FromDiscord<Phil> That is legitimately dope and provides a fair amount of more power than Java overloading
06:58:31FromDiscord<Elegantbeef> Well this is just normal procedure overloading
06:58:51FromDiscord<Elegantbeef> We also have all this applied to operator overloading 😛

07:00:09FromDiscord<Phil> Good thing I don't typecast procs that way
07:00:21FromDiscord<Elegantbeef> Eh it's not that bad you can make a quick macro to do it
07:00:26FromDiscord<Elegantbeef> Especially with micros 😛
07:01:12FromDiscord<Elegantbeef> Didnt or dont?↵(@aph)
07:01:30FromDiscord<aph> don't
07:01:35FromDiscord<aph> still confused lol
07:01:50FromDiscord<Elegantbeef> Nim allows you to use the parameter names of a procedure to call a specific prrocedure
07:02:03FromDiscord<Elegantbeef> You can use the `i = 10` to call the procedure with the `i: int`
07:02:07FromDiscord<aph> ohh get it now
07:02:10FromDiscord<aph> woah
07:02:24FromDiscord<Elegantbeef> I generally dont use it but I just mentioned it

09:11:47FromDiscord<Elegantbeef> Different system fonts
09:15:05FromDiscord<Elegantbeef> Oh and zoom you could do a few things to make that code a bit cleaner but no cigar on make it not crash on orc
09:19:27FromDiscord<Elegantbeef> For context https://play.nim-lang.org/#ix=3UrH
09:23:33FromDiscord<Zoom> But your version blocks in order?
09:23:57FromDiscord<Elegantbeef> It prroduces the same logic
09:24:05FromDiscord<Elegantbeef> Atleast afaict
09:24:37FromDiscord<Zoom> Why the hell do we have `blockUntilAny` at all then?
09:24:51FromDiscord<Elegantbeef> Probably just a case of the complexity of this problem that it behaves the same
09:24:56FromDiscord<Elegantbeef> Since each step is going to take longer
09:25:00FromDiscord<Zoom> Yeah, exactly
09:25:08FromDiscord<Elegantbeef> I dont get why block until any exists really either
09:25:13FromDiscord<Elegantbeef> we have a `isReady`
09:25:22FromDiscord<Zoom> It's not really my code, I just tried to show how to use `threadpool`.
09:25:34FromDiscord<Elegantbeef> Yea i know
09:26:02FromDiscord<Elegantbeef> Yea i dont get the point of block until any and araq seems to indicate it's not great
09:26:11FromDiscord<Zoom> Well, I prefer looping polling over stuff to be hidden from plain sight \:)
09:26:23FromDiscord<Elegantbeef> It also is more readable
09:26:41FromDiscord<Elegantbeef> `blockUntilAny` sounds like it is a void proc
09:27:04FromDiscord<Zoom> It's not great for shizzle.
09:27:33FromDiscord<Elegantbeef> Anyway you can still use `blockUntilAny` with any `FlowVar[T]`
09:27:42FromDiscord<Elegantbeef> Guess it's what i was trying to point out
09:29:01FromDiscord<Zoom> returning -1 is one thing. "If there is no flowVar left to be able to wait on, -1 is returned." is basically an instruction to write a while loop on that proc, but it doesn't work that way, embarrassingly.
09:29:37FromDiscord<Elegantbeef> Yea it really should just be `for x in blockUntil(myFlows)`
09:30:19FromDiscord<Elegantbeef> Or something better named
09:30:48FromDiscord<Elegantbeef> I dont know why recently i've just been on an iterator bend, implementing everything i can as them

09:35:09FromDiscord<Elegantbeef> Yea especially for macros it's what i crave
09:36:21FromDiscord<Elegantbeef> Being able to iterate the parameters of a proc just by doing `for param in myProc.params` or being able to iterate all the overloaded procedures in a symbol just by doing `for decl in mySym.routines`, makes code so much more readable and writable 😛

10:24:24FromDiscord<Zoom> We can't run with `--threads:on` on playground, right?
10:25:24FromDiscord<Rika> Nope
10:26:02FromDiscord<Zoom> Thought so. We can on wandbox though
10:50:30PMunchHmm, so I have C library that I'm wrapping. It has a `void *app` field for application specific data. I want to keep a Table of data in this variable. Now I'm not entirely sure how'd I'd do this and not have Nim just clean up the variable..
10:50:54PMunchI guess I could just put it in a wrapper object and then just put a pointer to it in that variable
10:50:58PMunchThat might be easiest
10:52:04FromDiscord<Yardanico> i mean, you can generally store any managed reference in that variable as long as you GC_ref it
10:52:25FromDiscord<Yardanico> so the refcount won't reach zero and Nim won't clean up the data
10:52:33PMunchHmm, that's true
10:53:18PMunchSo the way I've wrapped this so far is to create wrapper objects with destructors that calls the C-free options
10:53:42PMunchSo I could GC_unref in that destructor
10:53:59PMunchBut I could also just keep it in that wrapper object, and let Nim deal with it itself

13:34:38FromDiscord<Generic> I like to write offsetof instead of offsetOf because that's what I'm used to from C++
13:35:50FromDiscord<Generic> though I've also already had some troubles, especially with _ being ignored in identifiers when wrapping a C library
13:36:24FromDiscord<demotomohiro> case sensitive means you can create variables `filename` and `fileName` in one scope. That can confuse people.
13:37:40FromDiscord<Rika> you can enforce a lint for in-project files
13:37:55FromDiscord<Rika> i believe --stylecheck:on would do so
13:37:57FromDiscord<Rika> not sure
13:38:01PMunch@Alea, ah you've fallen into the common trap when it comes to case-insensitivity
13:38:29FromDiscord<Rika> well i understand
13:38:32FromDiscord<Rika> (edit) "well i understand ... " added "the issue"
13:38:37PMunchPeople tend to imagine I create a variable "myVariable" and then later in my code use it as "my_variable". This is obviously not something that people actually do.
13:38:56PMunchWhat it is useful for, as @Rika pointer out, is when you import a library someone else has written.
13:39:15FromDiscord<Generic> https://github.com/switchbrew/libnx/blob/master/nx/include/switch/nvidia/types.h#L379-L380
13:39:34FromDiscord<Generic> that was my concrete example which was pretty painful
13:39:47FromDiscord<Rika> i'd say that's dumb, what's the actual difference?
13:39:53PMunchIn Python for example I might import two different libraries, one using camelCase, and the other using snake_case. This means that my code now has to have mixed styles, not great
13:39:54FromDiscord<Rika> why is the difference a single underscore?
13:39:56FromDiscord<Rika> what does it mean?
13:39:56FromDiscord<Generic> NvColorFormat_V8_U8 and NvColorFormat_V8U8 are two different enums
13:40:05FromDiscord<Rika> yes but what does that difference mean
13:40:10FromDiscord<Generic> no idea
13:40:12FromDiscord<Rika> and isnt that confusing for programmers nonetheless
13:40:13FromDiscord<Rika> see
13:40:19FromDiscord<Rika> its a dumb difference
13:40:42PMunchNim's style-insensitivity means that I can write my code in whatever casing rules I prefer, regardless of what the libraries I use have opted for.
13:40:45FromDiscord<Generic> I know, though what should I do when I wrap the C library
13:41:01FromDiscord<Generic> what I did in the end was replacing all the underscores with v
13:41:10DixieFlatlineWhy Discord?
13:41:11FromDiscord<demotomohiro> `NvColorFormat_V8_U8`, `NvColorFormat_V8U8` and ``NvColorFormat_U8_V8` can confuse me.
13:41:15FromDiscord<Generic> which doesn't look to bad, because they're all in screaming case
13:41:46FromDiscord<Generic> ah though Nim identifiers can have unicode symbols, right?
13:41:52PMunchDixieFlatline, what do you mean?
13:41:55FromDiscord<Generic> maybe there is some symbol which looks like an underscore
13:42:19PMunchThat would be painful to type though wouldn't it?
13:42:19FromDiscord<Rika> In reply to @Generic "ah though Nim identifiers": yes but that's diabolical
13:42:28FromDiscord<Rika> In reply to @DixieFlatline "Why Discord?": ?
13:42:56DixieFlatlineHow come yall using Discord except myself and PMunch ?
13:43:08PMunchWhat Futhark does in that case is just append specificities to the name until it reaches something unique
13:43:30PMunchDixieFlatline, not all of them are, but the many different platforms are all routed via Discord I believe
13:43:33FromDiscord<Rika> In reply to @DixieFlatline "How come yall using": because i want to. how come you're using irc?

17:58:01FromDiscord<Rika> not really how that works i'd say
17:58:14FromDiscord<kevin> For a build script you're supposed to use setCommand (https://nim-lang.org/docs/nimscript.html#setCommand%2Cstring%2Cstring) maybe?

18:38:37FromDiscord<TryAngle> winim doens't have this function 😦
18:39:12FromDiscord<enthus1ast> then maybe convert both to a nim string or (since you're unsafe anyway) moveMem

20:03:12FromDiscord<spoon> copilot is good for repeating code that is very similar
20:03:27FromDiscord<spoon> i don't use it to generate procs though, it hasn't worked well even in python
20:03:38FromDiscord<spoon> or c++
20:03:49nrds<Prestige99> it's great for repeating mistakes, too

20:48:42FromDiscord<Phil> Etc.↵That kind of stuff is why I moved away from overloading generics and rather give them more specific names

20:57:24FromDiscord<Zoom> Using a lock. Better think twice about your structure and use message passing if you can↵(@TryAngle)
21:00:54FromDiscord<morgan> is there a way to get a string representation of a procedural type?
21:01:00FromDiscord<TryAngle> In reply to @Zoom "Using a lock. Better": is there something like Arc[T] or RwLock[T] like rust has? or does nim use other patterns for that?
21:01:46FromDiscord<Zoom> @TryAngle\: I recommend going through docs first\: https://nim-lang.org/docs/threads.html https://nim-lang.org/docs/manual.html#threads
21:02:14FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=3UuQ
21:02:34FromDiscord<Phil> That is, if you absolutely need a global variable
21:02:40FromDiscord<Phil> Generally, avoid those at all costs
21:03:14FromDiscord<TryAngle> In reply to @Isofruit "Generally, avoid those at": oh why? I come from rust where this was not doable at all and I thougth global variables were one of nims features?
21:03:33FromDiscord<Generic> global variables in non library code are good

21:03:46FromDiscord<Yayko> Hello all, I am in my learning of Nim, and I am on the ref object and the object, can someone explain to me the difference and which one to use in which case please?
21:03:54FromDiscord<TryAngle> In reply to @Generic "global variables in non": yes I'm writing a program, not a library
21:03:58FromDiscord<Phil> Global variables are possible, but generally they tend to be a not good idea.↵They add state that can affect your code in harder to predict ways
21:04:12FromDiscord<TryAngle> In reply to @Isofruit "Global variables are possible,": ah, that's true
21:04:15FromDiscord<Phil> (edit) "Global variables are possible, but generally they tend to be a not ... good" added "a"
21:04:35FromDiscord<Zoom> It depends on what you're writing. If it's some short script-like program, go for it. The more LoCs you have, the harder it gets to reason about your code↵(@TryAngle)
21:04:48FromDiscord<Phil> Avoiding global variables tends to make your code easier to reason about.↵There are scenarios where they're absolutely valid. E.g. I have yet to see a way to do resource pooling without a global variable
21:05:01FromDiscord<TryAngle> just figured I could use something like a "database" with read and write that is locked so I can avoid channels lol
21:05:10FromDiscord<Generic> it really depends on what you do
21:05:48FromDiscord<TryAngle> I want to separate my window / rendering and data processing thread
21:05:58FromDiscord<Zoom> You can make a shared resource, but it's always better to confine your procs to accessing only their args
21:07:12FromDiscord<Phil> Err could somebody better than me dive into ref object/object debate for Yayko?↵I for the most part stuck with "don't use ref-object" for some reason so I can't really contribute there
21:07:32FromDiscord<konsumlamm> In reply to @TryAngle "oh why? I come": there are reasons why Rust doesn't encourage global variables (it has them, but they're limited) and they're a bad idea in other languages too, for mostly the same reasons
21:07:53FromDiscord<Zoom> @TryAngle\: State is not your friend. The less, the merrier.
21:08:05FromDiscord<TryAngle> ok that is true zoom and konsumlamm
21:08:09FromDiscord<Generic> as a rule of thumb ref objects are good for larger objects passed around or in some datastructures like trees
21:08:10FromDiscord<TryAngle> I agree wit hthat
21:08:23FromDiscord<Phil> Wait, are non ref objects passed by value?
21:08:34FromDiscord<Phil> Is that the difference, pass by ref vs. pass by value in procs?
21:08:50FromDiscord<Generic> no, but once you need to mutate the object you need to use a var parameters
21:08:51FromDiscord<TryAngle> In reply to @Isofruit "Wait, are non ref": yes but procs that take: `var T` don't
21:09:13FromDiscord<Generic> and var parameters have limitations like they can't be captured by a closure
21:09:48FromDiscord<Phil> In reply to @TryAngle "yes but procs that": Yeh, makes sense, if you'd do a pass by value on a var T it wouldn't affect the object outside of the function call
21:10:24FromDiscord<Generic> they aren't passed by value above a certain size
21:11:04FromDiscord<TryAngle> In reply to @Generic "they aren't passed by": 🤔 are they a ref then
21:11:06FromDiscord<Phil> Check, so the pass by X behaviour is independent of the ref/non-ref type?
21:11:07FromDiscord<TryAngle> (edit) "then" => "then?"
21:11:58FromDiscord<TryAngle> (edit) "ref" => "referenced"
21:12:17FromDiscord<Generic> ref are traced pointers, the pass by reference (or rather pointer) for larger objects is hidden by normal Nim value type semantics
21:12:39FromDiscord<Zoom> Not exactly. References are primarily for many to one relations. They are managed pointers.↵(@Phil)
21:28:48FromDiscord<Phil> sent a code paste, see https://play.nim-lang.org/#ix=3UuW
21:29:13FromDiscord<Phil> That is if you want a speaking proc type
21:29:41FromDiscord<morgan> interesting
21:30:02FromDiscord<Phil> Otherwise you can just call type() on the proc itself or whatever variable you put it in. ↵For the above code↵`lala.type()` would also work and give you the actual proc signature
21:30:29FromDiscord<Phil> In this case the output would be `proc (){.gcsafe, locks: 0.} == type proc (){.gcsafe, locks: 0.}`
21:30:47FromDiscord<morgan> i probably don't need it, i might just have it use a hardcoded copy of the code
21:30:56FromDiscord<Phil> (edit) removed "0.} == type proc (){.gcsafe, locks:"
21:31:27FromDiscord<Phil> I think if you can generalize your problem into an outsourced proc with a decent name that's likely better than copy-paste and adjust
21:31:35FromDiscord<Phil> But that entirely depends on your problem
21:32:06FromDiscord<Phil> Myself I found passing procs as params around very useful
21:32:26FromDiscord<Phil> Particularly while giving these types of procs specific names to make their supposed task clear
21:32:37FromDiscord<Phil> (edit) "Particularly while giving these ... types" added "proc" | removed "of procs"
21:33:57FromDiscord<morgan> in this case i have a callback type `proc (input: varargs[string, `$`]): void` and callbacks of the form `callbackInt: proc (val: int64): void` also for float, string, bool, and a fuzzy bool object
21:34:17FromDiscord<morgan> this is for a library and its intended for those to be used by someone using it
21:34:49*Gustavo6046 quit (Ping timeout: 248 seconds)
21:35:43FromDiscord<Phil> Given that you're dealing with multiple different types I'm getting a feeling overloads with signatures that accomodate for the various primitive types might be sensible
21:35:48FromDiscord<morgan> so they could be anything from for flags, setting variable if it's more complex than the mode where it assigns the variable to a stored reference, to large procs with all the logic for a cli app
21:36:02FromDiscord<Phil> (edit) "Given that you're dealing with multiple different ... types" added "primitive"
21:36:22FromDiscord<Phil> What's the general purpose of these procs
21:36:28FromDiscord<Phil> What task do they accomplish?
21:36:46FromDiscord<morgan> it's how the framework i'm writing will call the code of the user who is using it
21:36:59FromDiscord<morgan> it parses the cli input and calls their code
21:37:11FromDiscord<morgan> yes i know others stuff exists that does this
21:37:19FromDiscord<morgan> im mostly writing this for learning experience
21:37:22FromDiscord<Phil> Ahh check, so it associates some CLI inputs with a proc to execute
21:37:26FromDiscord<morgan> yep
21:38:18FromDiscord<Phil> And you take care of the parsing of the params for them?
21:38:19FromDiscord<morgan> sent a code paste, see https://play.nim-lang.org/#ix=3UuY
21:38:22FromDiscord<morgan> yea
21:38:31FromDiscord<Phil> Hmmm that makes things a bit trickier
21:39:03FromDiscord<morgan> parsing subcommands, parsing flags, generating help commands automatically, it'll have command aliases
21:39:29FromDiscord<Phil> So based on flags, subcommands and param types you determine the proc to call
21:40:10FromDiscord<morgan> so the flag is a variant type and based on that it stores different procs
21:40:15FromDiscord<morgan> subcommands store one proc
21:40:30FromDiscord<morgan> flags will be set and call their callbacks first
21:40:33FromDiscord<morgan> then the subcommand
21:40:46FromDiscord<morgan> parent commands will not have their procs called
21:40:55FromDiscord<morgan> any further logic is for the callback to contain
21:41:40FromDiscord<Phil> Ugh, sorry I think I'm hitting my cognitive limit for the day. It's a cool idea and I'd love to keep chatting about this if you're around the chat once more later, but I can already feel my grasp on the subject matter slipping and I guess I really should be going to sleep
21:41:50FromDiscord<Phil> (edit) "Ugh, sorry I think I'm hitting my cognitive limit for the day. It's a cool idea ... and" added "for sure"

22:16:30FromDiscord<slymilano> Hey guys, how can I solve this `libwinpthread-1.dll` issue for my Nim project? https://github.com/sergiotapia/torrentinim/issues/28 - anyone have this issue for their projects?
22:16:53FromDiscord<Elegantbeef> Use MSVC i think is the answer
22:17:01FromDiscord<Elegantbeef> Or ship that dll with the binary
22:17:41FromDiscord<Elegantbeef> `libwinpthread` is the mingw posix library for pthread afaik, so when you use mingw for compiling you need it
22:18:15FromDiscord<Elegantbeef> I guess you can also try to statically link it
22:18:44FromDiscord<Elegantbeef> I assume your mingw is in your user path but not the admin path
22:19:00FromDiscord<slymilano> I don't have any devtools on my Windows machine. I'm testing this project as an end user.
22:19:53FromDiscord<slymilano> To statically link I would need to change this command, right? https://github.com/sergiotapia/torrentinim/blob/master/.github/workflows/release_asset.yml#L27
22:19:57FromDiscord<Elegantbeef> Then yea if distributing it you may want to consider static linking it or using msvc(think this uses a different thread api)

22:21:40FromDiscord<Elegantbeef> Ah it's `.a`
22:21:50Amun-RaElegantbeef: found another compiler bug, I still haven't reported the previous one
22:21:54FromDiscord<slymilano> Hm, I don't. I just off the shelf Nim packages. What if I just use `--app:staticlib` would that fetch and static link whatever it needs?
22:22:10Amun-RaElegantbeef: https://github.com/nim-lang/Nim/issues/19694
22:22:16FromDiscord<Elegantbeef> actually it might be ` --passL:"-static libwinpthread.a"`
22:22:29FromDiscord<Elegantbeef> No --staticlib is for exporting a library as static lib
22:22:46FromDiscord<Elegantbeef> Dont what?
22:23:41FromDiscord<Elegantbeef> Lol that's kinda funny amun
22:24:07FromDiscord<Elegantbeef> The reason the top level works is due to nim mangling the name, it doesnt realize it needs to mangle a name inside a procedure
22:24:47FromDiscord<Elegantbeef> As such https://play.nim-lang.org/#ix=3Uv5 works
22:24:48Amun-Rahmm, I haven't checked whether the function needs to be imported from C world or not
22:25:03FromDiscord<Elegantbeef> It does for this error to happen
22:25:50Amun-Rahmm
22:26:12FromDiscord<Elegantbeef> Nim generates symbols for it's own procedures so this wouldnt happen inside pure Nim
22:26:50Amun-Raah, right
22:27:15FromDiscord<Elegantbeef> https://wandbox.org/permlink/f6qDVoCViTV4lpk0 if you want to see
22:27:44FromDiscord<Elegantbeef> It's just a case of "When a variable is the same name as an importedC procedure Nim needs to generate a symbol for the variable"
22:27:44FromDiscord<slymilano> This seems related to my problem: https://github.com/greenfork/nimraylib_now/issues/66↵↵Not sure how I will include this as part of my github actions Windows build/release process.
22:28:13*Lord_Nightmare quit (Remote host closed the connection)
22:28:13FromDiscord<Elegantbeef> I mean does my suggestion not work?
22:28:19FromDiscord<Elegantbeef> Mingw has the static library
22:28:28FromDiscord<Elegantbeef> Atleast my linux mingw does, i doubt the windows one doesnt
22:28:34*Lord_Nightmare joined #nim
22:28:46FromDiscord<Elegantbeef> `/usr/x86_64-w64-mingw32/lib/libwinpthread.a` at this path if it's any help
22:29:35FromDiscord<slymilano> Trying to understand your suggestion. So in my Github action I would need to install mingw, find the libwinpthread.a and then use this as part of the build command specifically for Windows: `--dynliboverride:winpthread --passL:"-static -lwinpthread`
22:31:24Amun-Rahmm, --dynliboverride:winpthread --passL:libwinpthread.a?
22:33:04FromDiscord<slymilano> I'll try some stuff out thanks for the recommendations
22:33:58FromDiscord<TryAngle> is there a way to import enums without their "values"?
22:34:10FromDiscord<Elegantbeef> You dont need to install mingw it's the default with Nim
22:34:24FromDiscord<Elegantbeef> What do you mean import enums without their values?
22:34:31FromDiscord<Elegantbeef> What's the point of an enum without values
22:35:44FromDiscord<TryAngle> sent a code paste, see https://play.nim-lang.org/#ix=3Uv8
22:35:48FromDiscord<TryAngle> something like htat
22:36:05FromDiscord<TryAngle> so I don't clutter the scope with a lot of "junk"
22:36:10FromDiscord<Elegantbeef> Ah you want forced namespaces, Nim doesnt have any mechanism to force this anymore
22:36:38FromDiscord<TryAngle> lol
22:37:09FromDiscord<Elegantbeef> https://github.com/beef331/micros/blob/master/tests/test1.nim#L127-L149 here's a hack
22:37:14FromDiscord<Elegantbeef> "clutter the scope" is a sorta silly statement imo, but YMMV
22:37:22FromDiscord<Elegantbeef> I know prestige wants it
22:37:34FromDiscord<Elegantbeef> There is just no nice way of enforcing it whilst still allowing user choice
22:38:29FromDiscord<Elegantbeef> Speaking of prestige, i responded to your forum post if you havent seen
22:39:02FromDiscord<TryAngle> In reply to @Elegantbeef ""clutter the scope" is": yes in 90% of cases it's silly but now I work with nimgl and winapi and I already get namecollisions in just the hello world, I really want to reduce it a bit
22:39:25FromDiscord<TryAngle> and nimgl adds huge enums
22:39:29FromDiscord<TryAngle> (edit) "and nimgl adds huge enums ... " added "for example"
22:39:39FromDiscord<TryAngle> In reply to @Elegantbeef "Speaking of prestige, i": what forum post o_O
22:39:49FromDiscord<Elegantbeef> You can do `type MyEnum {.pure.} = enum`
22:39:53FromDiscord<Elegantbeef> Are you prestige?
22:40:11FromDiscord<TryAngle> ah lol, I thought u meant the noun
22:40:11FromDiscord<Generic> you can also use overloadable enums
22:40:30FromDiscord<TryAngle> (edit) "ah lol, I thought u meant the noun ... " added "and felt slightly attacked XD"
22:40:57FromDiscord<Elegantbeef> Yep overloadable and pure are both choices
22:41:00FromDiscord<Elegantbeef> The former is better imo
22:41:08FromDiscord<Elegantbeef> Though is behind a flag
22:41:19FromDiscord<TryAngle> yes so I would need to "fork" nimgl?
22:41:31FromDiscord<TryAngle> (edit) "nimgl?" => "nimgl to use pure pragma?"
22:42:31FromDiscord<Elegantbeef> Yes
22:43:28FromDiscord<Elegantbeef> Pure doesnt force `A1.` but it does allow ambiguous fields
22:52:56NimEventerNew thread by Domogled: JsFetch fetch, see https://forum.nim-lang.org/t/9087
23:04:38FromDiscord<TryAngle> when should I use doAssert and when assert?
23:06:31FromDiscord<exelotl> use `doAssert` if you want to check to _always_ happen, or `assert` if you want it to be disabled in a dangerous release build (`-d:danger`), or when `--assertions:off` is passed
23:06:36FromDiscord<exelotl> (edit) "to" => "the"
23:08:00FromDiscord<TryAngle> @ElegantBeef
23:08:03FromDiscord<TryAngle> I am so stupid
23:08:07FromDiscord<TryAngle> it's already pure lmao https://media.discordapp.net/attachments/371759389889003532/961401949197053992/unknown.png
23:09:15FromDiscord<Elegantbeef> So there is no issue
23:10:11FromDiscord<exelotl> it would be cool for `experimental:overloadableEnums` to become stable in 2.0
23:10:29FromDiscord<exelotl> (edit) "stable" => "the default"
23:10:38FromDiscord<Elegantbeef> it will in the next release
23:11:54FromDiscord<exelotl> oh sweet
23:13:07FromDiscord<Elegantbeef> 1.8.x not 1.6.x 😛
23:13:36FromDiscord<Elegantbeef> atleast afaik i might be misremembering
23:27:17FromDiscord<TryAngle> also any updates on: https://nim-lang.org/docs/manual_experimental.html#code-reordering ?
23:33:09FromDiscord<konsumlamm> In reply to @Elegantbeef "1.8.x not 1.6.x 😛": afaik the next release will be 2.0
23:33:32FromDiscord<konsumlamm> at least devel is now 2.0 with quite some breaking changes
23:34:04FromDiscord<konsumlamm> In reply to @TryAngle "also any updates on:": no
23:34:45FromDiscord<konsumlamm> i'd say "if there were, it would be in the manual", but that wouldn't be true
23:35:29FromDiscord<Elegantbeef> The update is it'll be removed for an automatic solution

23:36:41FromDiscord<konsumlamm> (that doesn't mean it'll happen any time soon though)
23:36:54FromDiscord<TryAngle> In reply to @exelotl "use `doAssert` if you": ah I see thanks
23:36:57FromDiscord<Elegantbeef> soon \:tm\:
