00:17 <mikdusan> a thought on enum ranges and @enumToInt https://gist.github.com/mikdusan/785c6feadf36a800b94f7c90e5fe86dd

02:38 <shachaf> The story with C++20 coroutines:

02:38 <shachaf> They ended up with a version that requires heap allocation (?) because implementing the version without heap allocation, which in theory should be backwards compatible (?), would involve complicated optimizations (?) that no compiler knows how to implement (?), and also they ran out of time so they won't include any library support (?)

04:35 <emekankurumeh[m]> are c++20 coroutines symmetric or asymmetric?

12:48 <gamester> "const a: ?[*c]i32 = null;" --> "unreachable: zig/src/codegen.cpp:gen_const_val_ptr:5911"

12:51 <gamester> "#include <math.h>", zig translate-c file.h, error: 'math.h' file not found. Ubuntu 18.10 here, hopefully not borked.

12:56 <gamester> I checked out a random commit from 4 days ago "fix incorrectly trying to memset at comptime", at that point zig translate-c still worked, but the c ptr issue is still there

13:03 <gamester> andrewrk: It seems optional C pointers never worked. You're missing a test :)

13:21 <gamester> andrewrk: This commit breaks zig translate-c for me (it can't find c stdlib headers) https://github.com/ziglang/zig/commit/1ec1097bd389b9af1b3e40d9edbc4c1c0b65f6a1

13:24 <andrewrk> gamester, try with `--library c` ?

13:24 <gamester> andrewrk: then I get "error: 'bits/libc-header-start.h' file not found"

13:24 <gamester> isn't programming fun?

13:24 <gamester> :)

13:25 <andrewrk> what version are you on?

13:26 <gamester> oh I'm now on the version that broke the translate-c, I'll go to most recent now

13:26 <andrewrk> I'm pretty sure I fixed that

13:26 <gamester> The #include <math.h> error was on the most recent version

13:27 <andrewrk> with --library c?

13:27 <gamester> no

13:27 <andrewrk> libc will probably be available by default once https://github.com/ziglang/zig/issues/514 is solved, but until then you don't get it unless you ask for it

13:28 <andrewrk> zig's C compilation facilities are isolated from the rest of the system

13:28 <gamester> ok so "zig translate-c file.h" is supposed to fail if file.h includes a c standard library, unless you do --library c?

13:28 <andrewrk> it might seem annoying at first, but then you don't get any users filing bug reports

13:29 <andrewrk> yes that's correct

13:29 <gamester> okay

13:29 <andrewrk> it will probably work without that once https://github.com/ziglang/zig/issues/514 is solved

13:41 <andrewrk> gamester, did it work with latest version and --library c?

13:47 <gamester> yes

13:47 <gamester> andrewrk: Feedback on an error message which might possible confuse: https://pastebin.com/raw/XXSkvQBT

13:49 <andrewrk> gamester, see also https://github.com/ziglang/zig/issues/1967

15:42 <develonepi3> andrewrk, updated zig ver c4887d7f. This is the cmd that I used to get zigmain.o zig build-obj -isystem ../../include/ -isystem /usr/lib/arm-none-eabi/include -isystem /usr/lib/arm-none-eabi -target armv7-freestanding-gnueabihf zigmain.zig

15:44 <andrewrk> develonepi3, looks good

17:23 <gamester> Since Zig is a C compiler now, I think it may be a good idea to sometimes interface with C code using more C code and interfacing with that instead, at least for now and when the C code uses varargs. C code can be such awful nonsense.

17:31 <scientes> what?

17:31 <scientes> when did zig become a C compiler?

17:32 <scientes> o i see

17:32 <gamester> https://github.com/ziglang/zig/commit/e5d4862e145c38ffc1111ee578ddcafc1e35ad57

19:35 <develonepi3> andrewrk, ultibo now calls zig https://github.com/develone/Ultibo_Projects/blob/master/ultibo_zig/zig.log

19:39 <andrewrk> develonepi3, what is this we're looking at?

19:40 <develonepi3> andrewrk, I created a kernel7.img which I ran on RRi2 see https://github.com/develone/Ultibo_Projects/blob/master/ultibo_zig/ZigTestProject.pas.

19:41 <develonepi3> andrewrk, https://github.com/develone/Ultibo_Projects/blob/master/ultibo_zig/zigmain.zig

19:42 <develonepi3> andrewrk, https://github.com/develone/Ultibo_Projects/blob/master/ultibo_zig/notesforzig.txt

19:43 <develonepi3> andrewrk, my bare metal with ultibo logging to file

19:43 <andrewrk> neat

19:47 <develonepi3> andrewrk, Only need 4 files kernel7.img bootcode.bin fixup_x.dat start.elf you tftp & telnet to the system running ultibo

19:48 <andrewrk> yep: https://github.com/andrewrk/clashos/tree/master/boot

19:48 <develonepi3> andrewrk, I create zigmain.o on Ubuntu and used fpc with Lararus on RPi3B+

19:48 <develonepi3> to create the kernel7.img
