01:24:54FromDiscord<heysokam> In reply to @devlop_gaming "Are there any working": nimgl/imgui are the only ones that I know. crazy outdated and abandoned, but no idea if they work↵someone used them not long ago, so they might 🤷‍♂️↵another option could be to use `futhark` to create a wrapper for `cimgui`
01:26:04FromDiscord<heysokam> futhark doesn't work for .cpp, so it cannot create bindings for dear directly. it needs a C api

02:01:24FromDiscord<devlop_gaming> Does nimgl is for opengl pretty sure
02:01:32FromDiscord<devlop_gaming> (edit) removed "Does"
02:04:33FromDiscord<heysokam> good to know. its abandonware, so it survived long enough without updates
02:12:01FromDiscord<devlop_gaming> I found something but it says imgui isn't in package list when I try to add it into my nimble file
02:18:11FromDiscord<devlop_gaming> Wait ik what I can try
02:38:51FromDiscord<devlop_gaming> In reply to @heysokam "good to know. its": How do I get cingui.dll?
02:48:08FromDiscord<heysokam> no idea. maybe someone who uses dear will know 🤷‍♂️
02:49:08FromDiscord<heysokam> I assume you have to compile cimgui, as someone said before, and copy/manage that with your buildsystem
02:49:37FromDiscord<devlop_gaming> Ok

04:03:15FromDiscord<m4ul3r> In reply to @devlop_gaming "Can you show me": I don’t remember. I did it back in like November and have been using the same DLL 💀
04:03:50FromDiscord<m4ul3r> IIRC, It was as simple as downloading a specific tag of cimgui that matched the version mentioned for the nim code and compiling that
04:10:41FromDiscord<devlop_gaming> But it's asking for a dll so I have to build it
04:17:24FromDiscord<heysokam> cimgui docs should provide info on how its built. would be really suprised if they didn't, given how popular dear is
04:18:04FromDiscord<devlop_gaming> I was looking for that but didn't find it
04:22:02FromDiscord<heysokam> In reply to @devlop_gaming "I was looking for": https://github.com/cimgui/cimgui?tab=readme-ov-file#compilation↵oh, the usual "I have instructions, what do you mean!!" but the instructions are garb if you don't already know how it works 🤷‍♂️

05:51:18Amun-Rawhat system are you on?
05:51:27FromDiscord<devlop_gaming> Windows
05:51:28Amun-Rawindows, am I right?
05:51:58FromDiscord<devlop_gaming> For some reason nim is looking for an old version of cimgui instead of the new installation I installed
05:52:03Amun-Rathere's procmon from sysinternals that you can use to trace your program calls
05:52:36Amun-Raset the filter to monitoring your app only and check for the errors; I bet some paths are not right
05:52:44Amun-Rahttps://learn.microsoft.com/en-us/sysinternals/downloads/procmon
05:52:45FromDiscord<devlop_gaming> How would that work if my program can't run
05:53:00FromDiscord<devlop_gaming> This is too much can you just tell me the problem?
05:53:24Amun-RaI can't for I don't posess a glass ball

05:53:55Amun-RaI see
05:55:23FromDiscord<devlop_gaming> This language got frustrating quickly
05:55:37Amun-RaIt's a skill issue, not a language one
05:55:58Amun-Raor, like we used to call it back in the days: PEBKAC
05:55:59FromDiscord<devlop_gaming> No it's not i literally never had this issue before
05:57:44FromDiscord<lainlaylie> nim basically assumes that you understand the systems you are using
05:59:28FromDiscord<devlop_gaming> Why does it keep trying to open the old version of the library anyway?? I tried removing the pjgs2, I tried removing the old version myself, I refreshed the pa page lists.
06:02:35FromDiscord<lainlaylie> when you say "open" the library do you mean `import`?
06:03:44FromDiscord<devlop_gaming> When it import a library it has to be able to open the file..
06:03:59FromDiscord<lainlaylie> is that yes or no?
06:04:48FromDiscord<devlop_gaming> No ig
06:05:18FromDiscord<lainlaylie> explain what you mean by open the library then
06:05:41FromDiscord<lainlaylie> it's difficult for anyone to help if nobody actually knows what you're having trouble with
06:05:54FromDiscord<devlop_gaming> I told you already
06:05:59FromDiscord<lainlaylie> good luck

07:25:45FromDiscord<kcvinker5420> In reply to @Amun-Ra "is this your custom": Yes
07:25:50Amun-Rayou can allocate the memory with alloc, alloc0, create etc. and free it with dealloc

09:03:00FromDiscord<microwave3607> thanks
09:03:08FromDiscord<microwave3607> so, if I understood right
09:03:17FromDiscord<microwave3607> `ref` isn't like `&` in c++
09:03:26FromDiscord<microwave3607> refs are objects traced by the GC
09:03:37FromDiscord<microwave3607> that I allocate with `new`
09:03:44FromDiscord<microwave3607> did I get it right?
09:03:51FromDiscord<lainlaylie> yes
09:04:21FromDiscord<microwave3607> In reply to @lainlaylie "yes": I don't seem to understand
09:04:47FromDiscord<demotomohiro> `ref` is similar to `std:shared_ptr` in c++.
09:04:47FromDiscord<lainlaylie> ...a shame you seemed an honest man?
09:04:58FromDiscord<0xfab_10> refs are like objects in java
09:04:58FromDiscord<microwave3607> In reply to @lainlaylie "...a shame you seemed": and the things I hold so dear
09:05:01FromDiscord<0xfab_10> or python
09:05:13FromDiscord<microwave3607> In reply to @fabric.input_output "refs are like objects": it was just a lain joke
09:05:25FromDiscord<microwave3607> I got what refs are
09:05:40FromDiscord<microwave3607> but that's a good analogy
09:05:42FromDiscord<microwave3607> thanks
09:05:54FromDiscord<0xfab_10> idk lain
09:05:56FromDiscord<lainlaylie> T() where T is a ref object also allocates, i find it a little nicer than `new`
09:06:27FromDiscord<0xfab_10> typeof(T()[])(...)
09:07:43FromDiscord<0xfab_10> what if instead of `ref T` we had `ref[T, A = GlobalAllocator]`

12:51:43FromDiscord<Laylie> sets are for testing membership. so you can do `boussole.incl n` and ask if `n in boussole`, for example

12:55:50FromDiscord<Laylie> what value do you want to get?↵(@jseb)
12:56:27FromDiscord<jseb> i thought boussole.n would be the enum value (n)

13:05:46FromDiscord<Laylie> a set is like a HashSet that's optimized for small types (such as an enum) where membership of the nth possible value is encoded by the value of the nth bit. in that sense the set itself has a value that you can get by casting it to an int. but I'm not sure what the purpose of `boussole.n` would be.
13:14:28FromDiscord<jseb> as it's encoded on bits, then directions.n == (directions.n or directions.e) should returns true.↵i think i will stick with classical enum n=1,e=2,s=4,o=8 (it's for checking walls in a maze)
13:16:05FromDiscord<Laylie> would that be something like `n in {n, e}`? have you checked the table here of set operations? https://nim-lang.org/docs/manual.html#types-set-type
13:17:01FromDiscord<jseb> ah thank you, i was lost in here : https://nim-lang.org/docs/manual.html#set-type-bit-fields (found with index of documentation)

13:43:47FromDiscord<0xfab_10> In reply to @griffith1deadly "we will be zig": more like C++ https://en.cppreference.com/w/cpp/memory/shared_ptr/allocate_shared
14:40:09FromDiscord<kcvinker5420> Does `=destroy` is guaranteed for every objects we use ?
14:41:01FromDiscord<kcvinker5420> I mean if we have a `=destroy` proc, is it guaranteed that it will run when the objects destroyed ?
14:42:00FromDiscord<kcvinker5420> Why I am asking because, I have 6 instances of an object and I had only one instance called `=destroy`

15:10:00FromDiscord<0xfab_10> mysql requires a password because you communicate it through the network

19:45:32FromDiscord<heysokam> In reply to @nervecenter "In fact if you're": are those bitflags?↵if yes, enum sets solve bitflags in a more ergonomic way, and are fully compatible with C
19:46:15FromDiscord<leorize> do note that compatibility with C is "accidental", aka. an internal implementation detail
19:46:41FromDiscord<leorize> the exact bit ordering is never documented nor tested
19:47:08FromDiscord<heysokam> is there any other way to represent enum sets in C other than enums and bitops?
19:48:25FromDiscord<leorize> if you're happy with how it works now, just submit a documentation update + some tests to make sure the repr stays the way it is

19:53:08FromDiscord<0xfab_10> In reply to @leorize "the exact bit ordering": in js codegen bitsets are objects with the key being the bit offset and the value being `true`
19:53:19FromDiscord<0xfab_10> last time I checked at least

20:19:30FromDiscord<leorize> weird, i'm pretty sure JS has accurate representation of uint32 that can be used for bitsets

20:39:06FromDiscord<Robyn [She/Her]> In reply to @jseb "it seems extremely complicated": Why not just use a seq set
20:39:14FromDiscord<Robyn [She/Her]> `seq[set[Compass]]`

21:27:51FromDiscord<tauruuuuuus> can someone ELI5 gotos vs setjmp in nim exceptions?
21:41:12FromDiscord<Elegantbeef> @tauruuuuuus goto uses gotos for the error handling instead of setjmp. When the code errors both go to the error handlers, the only difference afaik is the mechanism to get there
21:42:27FromDiscord<leorize> gotos basically set error global state, then return
21:43:38FromDiscord<leorize> it depends on the caller to know that there's an exception and to handle it
21:44:37FromDiscord<leorize> setjmp on the other hand "saves" the restore point (aka. where a handler exists), then jump straight from `raise` to the restore point, unwinding the stack in the progress
