00:03:45FromDiscord<sOkam! 🫐> also don't know if `free event` would be the same outcome in nim. feels wrong freeing a `ptr T` 🤔
00:05:36FromDiscord<Elegantbeef> `while ptr != nil` == `while myPtr` in C
00:06:03FromDiscord<Elegantbeef> You should use the xcb free instead of Nim's free
00:06:20FromDiscord<Elegantbeef> Nim's free is for it's allocator, we know xcb does not use your program's allocator
00:06:45FromDiscord<sOkam! 🫐> its not using xcb's free, its using C's free

00:08:16FromDiscord<sOkam! 🫐> never assigned anything in a while loop. i don't even use while loops most of the time
00:10:12FromDiscord<Elegantbeef> well you should be using the free to accompany the xcb alloc
00:10:13FromDiscord<Elegantbeef> So if it uses C's free you use C's free
00:10:13FromDiscord<Elegantbeef> Nope
00:10:14FromDiscord<Elegantbeef> `while (let ev = xcb.waitForEvent(conn); ev != nil)` is though 😛
00:10:14FromDiscord<Elegantbeef> Nim does not have return on assignment for good reason

00:21:01FromDiscord<sOkam! 🫐> @pmunch does futhark have any sort of support for enum sets?↵trying to `or` some enum values together, but they are really annoying to be calling `entry.ord` everytime, and creating converters is ugly and clashes so much that I banned it from my codebases 😦↵Did you already figure something out for this usecase?

00:42:59FromDiscord<sOkam! 🫐> its still the same issue, though. but with uglier syntax↵the underlying problem is that there are a lot of enums that were wrapped automatically and they don't have (or i don't know if they have) auto-generated ways to handle them

01:05:53FromDiscord<Elegantbeef> You can always change the procs to accept `set[YourEnum]` but it's very manual
01:05:56FromDiscord<Elegantbeef> Or make a indirection proc that does that
01:06:14FromDiscord<pmunch> And no, Futhark doesn't really have any kind of support for anything like sets. It just does the low level wrapping, no more, no less

03:19:34FromDiscord<aryzen> or am I doing something wrong?
03:20:54FromDiscord<leorize> you're using the wrong syntax
03:21:58FromDiscord<aryzen> oh ok
03:22:04FromDiscord<aryzen> let me look closer at the manual
03:22:40FromDiscord<leorize> it's just `:` -\> `=`
03:22:41FromDiscord<aryzen> right, I should have used an equal sign
03:22:59FromDiscord<aryzen> still does this though https://media.discordapp.net/attachments/371759389889003532/1208614612321443850/image.png?ex=65e3ed12&is=65d17812&hm=5f225f989c7576ae1293f7f1e0e5baff1205f94d9112ae240cda2130b842d5af&
03:23:49FromDiscord<Elegantbeef> The suggestion never suggests `object`
03:24:05FromDiscord<aryzen> that's on purpose?
03:24:11FromDiscord<Elegantbeef> Nope
03:24:12*def- quit (Quit: -)
03:24:18FromDiscord<aryzen> :S that's an issue then?
03:24:24FromDiscord<Elegantbeef> It's a type and typeclass but nimsuggest seemingly doesn't know that
03:24:33FromDiscord<aryzen> ah I see
03:24:43FromDiscord<aryzen> Should I use lsp or something?
03:24:47FromDiscord<aryzen> Or is there a setting I can tweak?
03:25:05FromDiscord<Elegantbeef> Nope no setting Nimsuggest just has many oddities
03:25:12FromDiscord<aryzen> argh. ok

03:25:25*def- joined #nim
03:25:47FromDiscord<Elegantbeef> I assume the reason is that `object` is a keyword and nimsuggest does not know how to suggest keywords

03:29:35FromDiscord<Elegantbeef> But they promised cross platform!
03:29:45FromDiscord<aryzen> yeah it works across multiple windows pcs!
03:30:02FromDiscord<aryzen> mission accomplished

07:40:20FromDiscord<odexine> T -> whatever enum response_type holds
07:41:00FromDiscord<odexine> the values of such enum must be roughly sequential and not the value you're ANDing against

07:44:21FromDiscord<sOkam! 🫐> In reply to @odexine "T -> whatever enum": as you can see, it contains no enum, its a `uint8`. I'm struggling to find the docs, as this value is hardcoded in all of the xcb examples and the documentation is basically nonexistent for the field 😔↵I guess I could makeup an enum manually and use that to check.↵How would you do this check specifically with an enum set?

07:46:02FromDiscord<odexine> In reply to @heysokam "as you can see,": idk, good luck if everything is hardcoded like that because that just makes it difficult to translate since you dont know the meaning of anything
07:46:13FromDiscord<sOkam! 🫐> In reply to @odexine "idk, good luck if": yeah that's the probl
07:46:36FromDiscord<sOkam! 🫐> In reply to @odexine "C flag enums often": i know this. my question is specifically about doing the equivalent to `& ~0x80`
07:47:08FromDiscord<sOkam! 🫐> (edit) "`&" => "`thing &"
07:47:49FromDiscord<odexine> thing & ~0x80 is essentially a check for some value not being in the set, or so
07:47:57FromDiscord<odexine> actually no, miswrote
07:48:29FromDiscord<odexine> its a filter for that specific item, it filters out that item from the set
07:50:31FromDiscord<sOkam! 🫐> so we are accessiing the value of the field without whatever is contained in the bit at `1_000_0000` I guess 🤔
07:51:32FromDiscord<odexine> pretty much
07:51:47FromDiscord<odexine> so depending on how that value is really used, it might be a set or not
07:51:59FromDiscord<odexine> usually it is but sometimes it isnt so

08:54:38FromDiscord<fosster> guys, do you think is better to mark a toString function (`$`) as `func` instead of `proc`? In my opinion yes because it acts more like a `func` considering in only gives back the result
08:56:01FromDiscord<fosster> I know it seems like a pretty dumb question, but I always see `$` functions marked as `proc` and I don't agree with it
08:57:00FromDiscord<Elegantbeef> Nim has func inference so if it's a proc that's truly a func it's fine
08:57:06FromDiscord<Elegantbeef> But if you want it as a func go ahead
08:57:20FromDiscord<Elegantbeef> I do not use func as much as I should
08:58:04advesperacitI forget it exists
08:58:23FromDiscord<fosster> neither I, but I wonder how does it infer it
08:59:12FromDiscord<Elegantbeef> If the proc has a side effect it's not marked `noSideEffect`
08:59:15FromDiscord<Elegantbeef> It's quite simple
09:06:26FromDiscord<sOkam! 🫐> is it possible to use an enum set as the `case ... of myset: ` instead of using single values separately?
09:06:48FromDiscord<Elegantbeef> You can use array, set, and range values as long as it's constant
09:07:20FromDiscord<sOkam! 🫐> i had no idea, thought only ranges were an option. ty
09:08:58FromDiscord<Elegantbeef> Well unless you want to use a constant there is not much benefit in the set
09:09:24FromDiscord<Elegantbeef> `of A..B, C, D, E, F, X..Z` is the exact same as you'd do in the set
09:15:43FromDiscord<fosster> is there a function in the module `std/uri` or perhaps in some other module that checks if an URI/URL is valid?
09:20:20FromDiscord<Elegantbeef> Less than ideal but you could parse it then check the components are fine

19:57:33FromDiscord<alex.boisvert> I think the two most common way in Nim would be:↵1) as a typed function/closure (more or less what you described above), this is the "functional way"↵2) with an object hierarchy + method(s), this is the "OO way"↵Both of these give you dynamic dispatch, such that the Strategy doesn't have to be selected at compile time. If you're ok with compile-time, then it opens up concepts/generics and compile-time conditionals.
19:57:41FromDiscord<alex.boisvert> (edit) "way" => "ways"

19:59:17FromDiscord<itr_> In reply to @alex.boisvert "I think the two": compile time is fine, just wanted to be able to swap a strategy by just changing one argument (at compile time) ↵Do you know any examples I can look at
20:00:08FromDiscord<itr_> compile time conditionals might get a little messy though
20:41:39FromDiscord<Elegantbeef> make a proc that takes in a `static proc(...)`↵(@itr_)
