00:19 <donpdonp> as soon as i add var bytes : [255]u8 = undefined;

00:19 <donpdonp> the wasm tries to import 'memcpy', which i dont have an implementation for.

00:20 <donpdonp> i know its very early for webasm. im not sure if there is supposed to be a 'libc' for webasm yet

00:25 <andrewrk> donpdonp, zig provides memcpy (and more) automatically when you use build-exe or build-lib

00:27 <andrewrk> that's going to depend on zig using the wasm linker correctly - which I believe we are close to but might need a couple patches

06:50 <emekoi> well i got a zig program to work with libc in mingw, but i had to use mingw's linker

06:50 <emekoi> it must be doing some weird magic to get msvcrt to link correctly

06:51 <kristate> hey emekoi

06:51 <emekoi> what's up?

06:51 <kristate> how are you?

06:53 <emekoi> good, what about you?

06:54 <kristate> pretty good -- it's almost 4pm in kyoto

06:55 <emekoi> it's almost 1am where i live

12:59 <porky11> hi

13:08 <porky11> C is good for writing cross language libraries, but it doesn't allow compile time generic code

13:08 <kristate> hi porky11

13:08 <porky11> and even for c++ it's not possible to export compile time generic code to other languages

13:09 <porky11> but zig also doen't help there, I assume, right?

13:10 <kristate> what do you mean by comptime generic code?

13:11 <porky11> for example vector math (Vector<T, N>)

13:12 <kristate> porky11: the C ABI does not have support for generics and comptime code, but of course, zig can export its translation units to the C ABI

13:13 <porky11> yeah, I thought so

13:13 <kristate> the C ABI meaning the C ABI -- not the zig C ABI layer

13:19 <porky11> I just thought, a cross language way to import generics (similar to .o .so or whatever c can compile to) would be a good idea, and so I hoped, since zig aims to be a better C with generics, it maybe implements something like that

13:23 <kristate> well, you would write your code in zig, and then write some wrapper functions to talk with C

13:28 <porky11> the problem is, when I switch language, I have to rewrite a bunch of my libs, so I started to use C for most of my libs, so I just have to write wrappers for other languages, which is much simpler, but with generics that's not possible. Assuming I write a generic vector math library in zig and want to use it in rust later, I cannot simply write a wrapper

13:31 <porky11> I either have to rewrite it or instantiate all important types (maybe vectors up to 10 dimensions), but when I need some less important types, it won't work, and when I don't use most of the types, filesize will be too large

13:34 <kristate> porky11: that's why zig is so important -- it's the closest thing we have to a true c competitor. Rust is too runtime centric

13:38 <porky11> rust was just an example. There are langauges with similar goals to zig like scopes, odin, dale. For example I wrote a nice library in scopes and it would be cool if I could use it in zig without having to rewrite most of it
