06:30:04ElronndI was reading over this https://github.com/nim-lang/Nim/wiki/Nim-for-Python-Programmers and it says this "Strings are always unicode."
06:30:46Elronnddoes that mean something's actually enforced by the compiler, or is that just what the stdlib functions expect?
06:36:57Elronndreading over https://github.com/nim-lang/Nim/wiki/Nim-for-C-programmers it looks like the preferred way of printing out multiple values is echo "foo", bar, "baz". Is it possible to use c-style string formatting? Perhaps the way python and d do it where %s is used for everything and calls toString (or equivelant) on its parameter?

14:53:26*nhywyll joined #nim
15:00:01FromGitter<aboisvert> yes, definitely possible to define generic procs in concepts
15:00:10FromGitter<aboisvert> don't understand your code sample, though
15:00:45FromGitter<aboisvert> are you trying to apply the concept to `int` ?
15:01:19FromGitter<Smaehtin> Yes, I am in this example
15:02:30FromGitter<Smaehtin> Because there is a proc `stuffT (...)` defined for `int`, it should fill the requirements of being a `Test` concept type
15:03:26FromGitter<Smaehtin> Do you happen to have an example of specifying generic procs inside of a concept by any chance? I've been searching for a while and haven't had any luck so far finding one
15:04:57FromGitter<aboisvert> Looking for one ...

15:11:37*ShalokShalom joined #nim
15:21:28FromGitter<aboisvert> sorry, not finding one. trying with 0.17 but getting same issue. taking a look at #head
15:22:53FromGitter<Smaehtin> It actually works if I replace the generic parameter with `auto`, so: `proc stuffT (i: int, value: T): T` becomes `proc stuff(i: int, value: auto): auto`
15:23:37FromGitter<Smaehtin> Which is strange, because as far as I remember, `auto` parameters are converted to generic parameters anyways
15:29:33*Trustable joined #nim
15:30:32FromGitter<Smaehtin> Scratch that, that was another test I was doing using `typedesc[auto]`...

18:04:51Xeis there a way to get the gc stats from GC_getStatistics as a struct?
18:10:11Araqno, it uses Unix's design. strings are good enough nobody needs structured data
18:12:22dom96hah
18:12:42dom96We would love it if you created a PR that made it return a struct :)
18:13:24Araqthat's true but the object's fields depend on the used GC
18:13:41Araqand are subject to change
18:16:40dom96Speaking of things that return a string: getStackTrace (or w/e it's called) should return a struct of some sort
18:22:44Araqok with me but don't make it return seqs of strings please
18:22:55Araqreturn what the runtime actually really uses

20:10:00UxerUosprDoes anyone have a good resource on writing multi-threaded/process programs? I've not done it before in any language and it'd be a good excuse to delve deeper into Nim.
20:10:31FromGitter<zacharycarter> Threads are tough in Nim with the default GC UxerUospr
20:10:48*Tester_ quit (Client Quit)
20:10:58FromGitter<zacharycarter> not impossible but with the thread local heaps memory management becomes a little more difficult
20:11:07FromGitter<zacharycarter> you have to resort to channels or use shared unsafe memory
20:11:13FromGitter<zacharycarter> that is not garbage collected
20:11:42FromGitter<zacharycarter> you can use thread pool and spawn

22:47:43Araqthat was decided by me before the project got track ;-)

22:51:36ipjkI do realise `*` is for public, which I quite like.
22:53:42FromGitter<zetashift> @Araq got any recommendations on courses/books/articles that I can read how I can into imperative/procedural programming? Coming as a hobbyist from C# and Kotlin, I can't seem to structure programs well/efficient in Nim
22:54:26ipjkzetashift: Both C# and Kotlin are imperative languages.
