00:37:14FromDiscord<fae> So many features in Nim lol. Was trying to get way too fancy with the macrocache module, and now I have just figured out there’s a compileTime pragma lol
00:40:07FromDiscord<Elegantbeef> Well depending on what you're doing, but macrocache will be better as it will work with the IC
00:46:14FromDiscord<fae> Good to know
00:47:04FromDiscord<fae> Does it persist to some db or something
00:48:28FromDiscord<Elegantbeef> I think it's just easier to handle serialization for the cache as such is what is prefered
00:48:42FromDiscord<Elegantbeef> Since it stores AST instead of arbitrary types
00:49:56FromDiscord<Elegantbeef> But yes it's stored in/with the rod files(name of the IC files)

12:35:24FromDiscord<fae> is compiling to cpp generally fine if you are intending to use the src on ios/android? or is generated c code much easier to use on those platforms
12:38:24FromDiscord<fae> And that may be more of an XY problem question. Basically I'm trying to static link https://github.com/facebook/yoga in, but since it's a c++ lib I need to compile with `nim cpp`, and just wondering if that will create portability problems down the line. It seems like `nim c` is generally favored.

12:52:15FromDiscord<dom96> on iOS you may need to compile to Obj C
12:52:22FromDiscord<dom96> something to keep in mind
12:52:26FromDiscord<dom96> for android C++ should be fine
12:55:00FromDiscord<fae> I suppose that also means if I try to turn it into a nimble package that any project relying on it would need to be compiled as cpp

13:12:56FromDiscord<cabboose> I am struggling to make even a simple example of chronos callbacks work
13:13:07FromDiscord<cabboose> I thought I would be able to easily access the futures data within the callback
13:13:25FromDiscord<cabboose> but if it's outside the scope of the cb it complains about accessing GC data
13:14:03FromDiscord<cabboose> using the udata thing seems tedious to have to cast the pointer to the correct data type especially if it's nested
13:14:14FromDiscord<cabboose> is there any examples out there in the wild to hazard a look at?

19:33:46FromDiscord<kamy> I need a way of storing a bunch of wStaticBitmap because I need to hold them to change later. The amount is variable.
19:34:36FromDiscord<haxscramper> What is `wStaticBitmap`? Can you show the whole error, I don't think your description matches the code you provided. `sBM` is an object, you are not trying to add type
19:34:52FromDiscord<haxscramper> ah
19:34:53FromDiscord<haxscramper> ofc
19:34:57FromDiscord<haxscramper> `let imgSeq`

23:55:43FromDiscord<Iapetus11> 👍
23:55:45FromDiscord<aleclarson> what could be the cause of `template/generic instantiation of "some" from here` when using `some` from `options`?
23:55:55FromDiscord<Yardanico> In reply to @aleclarson "what could be the": that's not the full error message
23:55:59FromDiscord<Yardanico> show the full error message that the compiler shows
23:56:14FromDiscord<Elegantbeef> The issue with using `randomize` there is you've now overwritten the state so if someone had seeded it you've fucked them over
23:56:27FromDiscord<aleclarson> In reply to @Yardanico "that's not the full": it's the full message that VS Code shows, unless there's somewhere else i can look
23:56:27FromDiscord<Yardanico> yeah it only makes sense to call randomize() in apps
23:56:33FromDiscord<Yardanico> In reply to @aleclarson "it's the full message": check the compiler output as I said
23:56:40FromDiscord<Yardanico> compile the nim file and show the compiler output
23:56:50FromDiscord<Elegantbeef> The compiler is the best way to see issues
23:57:08FromDiscord<Yardanico> in libraries you don't want to call randomize() as that should be left for the application that's using the library
23:57:14FromDiscord<Yardanico> at most you can have a local random state
23:57:21FromDiscord<auxym> @ElegantBeef Is it a new recommendation to prefix stdlib imports with `std/`? I've been seeing it recently but I don't recall hearing about it before
23:57:32FromDiscord<Yardanico> In reply to @auxym "<@!145405730571288577> Is it a": yes, it is
23:57:37FromDiscord<aleclarson> In reply to @Yardanico "check the compiler output": oh very nice
23:57:42FromDiscord<Yardanico> new modules are only created in std/ prefix
23:57:53FromDiscord<aleclarson> > Cannot prove that 'result' is initialized. This will become a compile time error in the future.
23:57:55FromDiscord<Yardanico> so it's much better to import all stdlib modules with the std/ prefix
23:58:01FromDiscord<Elegantbeef> You also may want to expose procs that take a `Rand` object
23:58:19FromDiscord<auxym> I see. Any further reading? A blog post or changelog or something?
23:58:19FromDiscord<Yardanico> if you want to import multiple, it's possible the same way as before on a single line - `import std/[strutils, strscans, strformat]`
23:58:33FromDiscord<Yardanico> In reply to @auxym "I see. Any further": can't think of anything like that, it's not like this change requires some deep reading
23:58:38FromDiscord<Elegantbeef> The 1.6 docs go so far to put `std/modulename` in the title
23:58:41FromDiscord<aleclarson> In reply to @aleclarson "> Cannot prove that": so using a `not nil` variable with `options` is discouraged, i guess
23:58:45FromDiscord<Yardanico> In reply to @Elegantbeef "The 1.6 docs": yeah, that too
23:59:00FromDiscord<Yardanico> std prefix is there so that user modules (or modules from nimble) don't clash with stdlib ones
23:59:10FromDiscord<Yardanico> btw, for nimble packages you can use the `pkg` import prefix
23:59:22FromDiscord<auxym> Well, yeah, just wondering why everyone started doing that
23:59:25FromDiscord<Yardanico> `import pkg/[regex, mathexpr]`
23:59:34FromDiscord<Elegantbeef> Makes it harder to clash with modules accidently
23:59:35FromDiscord<Yardanico> In reply to @auxym "Well, yeah, just wondering": as I said, so that it doesn't clash with user modules
23:59:44FromDiscord<Elegantbeef> unless you're daft enough to make a folder named `std` \:P
23:59:44FromDiscord<auxym> I see.
