00:01:31FromDiscord<Elegantbeef> It has to be a generic cause it's polymorphic
00:01:37FromDiscord<Elegantbeef> There are so many interpretations of it
00:02:11FromDiscord<Elegantbeef> In some places there is even an antithesis of it so it certainly is a typeclass cause you can do `not Heaven`

00:26:49*raynei quit (Ping timeout: 264 seconds)
00:28:40FromDiscord<Arkanoid> I'm trying to reformat my code to light up the issue. Basically it's recursive import due to shared state in my js app
00:34:17FromDiscord<Arkanoid> since all components have a render proc, but also the pages have a render proc, and pages contains components, I'm trying to shred some light if I should just dedup procedures, or implement dynamic dispatch, or use some ninja generics
00:34:34FromDiscord<Elegantbeef> I mean if you can do it statically generics are the best bet
00:34:40FromDiscord<Elegantbeef> If you cannot do it statically use some dynamic dispatch
00:35:00FromDiscord<Elegantbeef> Might I suggest traitor 😛 https://github.com/beef331/traitor#what-does-it-do
00:35:54FromDiscord<Arkanoid> I fear traitor as I don't understand it. I mean, it's beautiful, too beautiful, but far from my level of confidence
00:36:07FromDiscord<Elegantbeef> It's much simpler now
00:36:35FromDiscord<Elegantbeef> It's practically just a way to do interfaces that does not require the user to do `type Bleh = ref object of RootObj`
00:36:55FromDiscord<Elegantbeef> You define the procs you want to match then simply convert to a trait object that encapsulates them
00:37:22FromDiscord<Elegantbeef> https://github.com/beef331/traitor/blob/master/traitor/streams.nim I even implemented `FileStream` and `StringStream`
00:37:52FromDiscord<Elegantbeef> sent a code paste, see https://play.nim-lang.org/#pasty=bDiTSWvfgoFT
00:40:30FromDiscord<Arkanoid> what's the advantage over Stream = ref object of RootObj + overriding methods on child objects?
00:40:47FromDiscord<Elegantbeef> This does not require runtime dispatch always to use the child objects
00:40:57FromDiscord<Elegantbeef> It can be statically dispatched if you do not need it
00:41:05FromDiscord<Elegantbeef> Plus this works with `object` so it's not annoying to write destructors
00:41:30FromDiscord<Arkanoid> last one is a big plus
00:41:31FromDiscord<Elegantbeef> It also uses a vtable so it's faster to dispatch than the Nim `method`
00:41:47FromDiscord<Elegantbeef> I havent benchmarked the last though, it's just a theory

01:18:43FromDiscord<Elegantbeef> wasnt it working with `pane.wEvent_Size do: ....`?
01:18:54FromDiscord<Elegantbeef> that's `panel.wEvent_Size(proc() = ...)`

01:20:19FromDiscord<Elegantbeef> it's calling a proc named `wEvent_Size` with your anonymous proc

01:21:01FromDiscord<piman_discriminator_1010> :mood:

01:21:35FromDiscord<Elegantbeef> I'm saying it's a constant and a event since Nim has overloading
01:22:42FromDiscord<piman_discriminator_1010> alright, I'm going to blame this confusion on wNim docs then
01:23:05FromDiscord<piman_discriminator_1010> you say an event, like C# events?

01:26:54FromDiscord<Elegantbeef> Nim doesn't have events
01:26:58FromDiscord<Elegantbeef> The package has events
01:29:15FromDiscord<piman_discriminator_1010> so it's a `const` and a `proc` then
01:31:59FromDiscord<Elegantbeef> Sure

02:10:36FromDiscord<Arkanoid> nevermind, solved, `select` is a keyword of karax
