11:26:23FromDiscord<.tokyovigilante> ie using `{.varargs.}` instead of `va_list`?
11:27:04FromDiscord<.tokyovigilante> This makes it hard to write a Nim function for `logtv` as I'm not sure how to access the varargs. I had just been using `vsnprintf` to write it into a char buffer.
11:28:21FromDiscord<.tokyovigilante> I can't quite figure out if `{.cdecl, varargs.}` even makes sense, i.e. can the compiler convert between Nim and C varargs?
11:31:08*ntat joined #nim
11:33:12FromDiscord<.tokyovigilante> sent a code paste, see https://play.nim-lang.org/#pasty=GiwPNzPg
11:33:31Amun-Ra{.varargs.} is en equivalent of C's ...
11:35:09FromDiscord<.tokyovigilante> Ok, so {.cdecl, varargs.} should work? Just not sure how to implement the callback in Nim so I can access the arguments in that case, ie past `a6`.
11:35:23FromDiscord<.tokyovigilante> (edit) "{.cdecl, varargs.}" => "`{.cdecl, varargs.}`"
11:40:35Amun-Ravarargs should work for … (snprintf, etc) but not for va_list ones (vsnprintf, etc)
11:41:18FromDiscord<demotomohiro> It seems when you call C functions with variable number of arguments, they need to have `varargs` pragma.↵But when you need to implement C functions with variable number of arguments that are called by C, you need to use `va_list` instead of `varargs` pragma in order to access arguments.
11:42:49Amun-Rathose are two methods for passing a variable number of arguments to a function
11:44:32Amun-Raif you need to pass … to a function that accepts va_list you have to build it with va_start, va_copy, va_end, etc.
11:45:37Amun-Raand I don't think va_list is event exposed to nim side in stdlib
11:53:04*ntat quit (Quit: Lost terminal)
11:53:18FromDiscord<dawidek.2137> nim has special syntax for (`=programCounter`) but there is no such thing for getters, right?
11:53:30FromDiscord<dawidek.2137> (edit) "nim has special syntax for ... (`=programCounter`)" added "setters"
11:55:26FromDiscord<fabric.input_output> `proc a(b: C): A = b.someting` you can use it like `b.a`
11:55:29FromDiscord<fabric.input_output> essentially a getter
11:56:17FromDiscord<dawidek.2137> thanks
11:57:55FromDiscord<lainlaylie> https://nim-lang.org/docs/manual.html#procedures-properties
11:59:32Amun-Radawidek.2137: you can even shadow object field name with a func at it'll act like a getter

14:26:00FromDiscord<nnsee> no, i don't think so
14:26:16FromDiscord<devlop_gaming> 0 is success and 1 is an error
14:26:51FromDiscord<nnsee> In reply to @devlop_gaming "0 is success and": usually, yes, but not in SDL3
14:26:51FromDiscord<nnsee> https://wiki.libsdl.org/SDL3/README/migration
14:26:58FromDiscord<devlop_gaming> Huh?
14:28:05FromDiscord<devlop_gaming> I don't see what you're talking about
14:28:33FromDiscord<nnsee> literally the first paragraph

14:29:54FromDiscord<devlop_gaming> I still don't follow

14:33:42FromDiscord<nnsee> your function is returning `true` on success, therefore it is returning `1`

14:35:16FromDiscord<nnsee> i don't know, you haven't posted any errors and i'm not clairvoyant

14:36:47FromDiscord<nnsee> sure, but again, that's not very helpful without the actual error message
14:37:26FromDiscord<nnsee> actually, i guess i am clairvoyant
14:37:58FromDiscord<nnsee> you can't import the function because there's no function called that in SDL3

14:39:33*amadaluzia joined #nim
14:39:52FromDiscord<nnsee> look at the function name in the documentation, then look at the function you're trying to import
14:43:20FromDiscord<devlop_gaming> Same error
14:43:24FromDiscord<devlop_gaming> In reply to @devlop_gaming "Traceback (most recent call": ^
14:43:55FromDiscord<nnsee> that's not very helpful without the code :p
14:43:58FromDiscord<devlop_gaming> Right whee i try to open the font
14:44:08FromDiscord<nnsee> i don't see line 19 in the code you pasted
14:44:19FromDiscord<devlop_gaming> sent a code paste, see https://play.nim-lang.org/#pasty=KBNEFBtd
14:46:09FromDiscord<nnsee> well line 19 is you already using the font. as per the documentation, if opening the font fails, it returns a null pointer - if you're operating on a null pointer, it's no wonder it's crashing. you need to specifically check for the null pointer and actually use SDL_GetError to print the actual error message if it is null
14:47:19FromDiscord<devlop_gaming> I said multiple times it won't let me import it for some reason
14:48:29FromDiscord<devlop_gaming> Wait nvm
14:48:33FromDiscord<spotlightkid> learn to read error messages you must, young jedi...

14:50:28FromDiscord<devlop_gaming> (edit) "right\" => "right"
14:50:33FromDiscord<nnsee> are you actually `echo`-ing the result from SDL_GetError?
14:50:40FromDiscord<nnsee> In reply to @devlop_gaming "could not import: TTF_GetError": again, wrong function name...
14:51:58FromDiscord<devlop_gaming> In reply to @nnsee "again, wrong function name...": Oh then i don't get anything when printing the error
14:52:49FromDiscord<nnsee> can you post the code

14:53:51FromDiscord<nnsee> (if possible, please use https://play.nim-lang.org for sharing longer code snippets, there's a share button on the bottom left)
14:54:45FromDiscord<nnsee> how are you importing SDL_GetError? also you should actually check whether it _is_ returning a null pointer, i was just guessing
14:55:10FromDiscord<spotlightkid> And for shorter ones, you can use code-fences (triple back-tick before/after the source code) here on matrix. you can even have hi-lighting if you but `nim` after the initial triple back-tick.
14:55:14FromDiscord<devlop_gaming> I installed sdl3 using nimble and put it's dll in my src folder
14:56:57FromDiscord<nnsee> oh, SDL_GetError is in the nimble library, and the import seems fine to me
14:57:17FromDiscord<nnsee> you need more checks in your code for null pointers for functions that can return null as per the documentation to figure out exactly what's going wrong
15:00:29FromDiscord<devlop_gaming> Checks where?
15:01:07FromDiscord<nnsee> ... the return values for functions that can return a null pointer
15:01:28FromDiscord<nnsee> TTF_OpenFont, for one
15:01:33FromDiscord<nnsee> the documentation is your friend
15:01:52FromDiscord<devlop_gaming> I literally have it open right now
15:02:10FromDiscord<devlop_gaming> But i'm asking where should i put checks
15:02:12FromDiscord<nnsee> i suggest also reading it :p
15:02:25FromDiscord<nnsee> In reply to @devlop_gaming "But i'm asking where": respectfully, i'm not reading the documentation for you
15:02:50FromDiscord<devlop_gaming> I really don't get what you mean
