13:21 <Barabas> Is there an easy/elegant way to make a (comptime) loop over all the possible enum values of a specific enum type?

14:14 <gamester> Barabas: I'm not used to comptime things but this works: https://pastebin.com/raw/jQrXceMx

14:20 <Barabas> Cool, thanks!

14:22 <gamester> Barabas: as you can see there is some redundancy between @typeinfo and other @ functions, later you'll probably use std.meta which just uses @typeInfo: https://github.com/ziglang/zig/issues/1104

14:22 <gamester> will just use* - std.meta does not exist yet, I think

14:23 <gamester> or at least I think it's not finished

14:23 <Barabas> ok

14:24 <Barabas> the fields.value is a bit weird, as I expected it to return ... oh well maybe it makes sense. At first I thought it would be of the enum type, but it's a usize.

14:24 <Barabas> or sorry, comptime_int

14:27 <gamester> you can get the tag type like this: @typeInfo(your_enum).Enum.tag_type

14:27 <gamester> also take a look at std.meta, it seems there's good stuff in there

15:11 <Barabas> How do you make a field of a (tagged) union active?

15:11 <Barabas> I tried doing

15:11 <Barabas> my_union.Field = undefined;

15:11 <Barabas> but there it complains that it accesses an inactive field :(

15:11 <hio> I think you have to reinitialize the whole thing

15:12 <hio> my_union = union { .Field = 3 }

15:14 <Barabas> Hm... ok, yes that seems to work.

17:37 <gamester> andrewrk, strange error: https://pastebin.com/raw/rWchzfqV

17:53 <andrewrk> gamester, fixed: https://github.com/ziglang/zig/commit/c8453454e16ce6188fb80f2fed8032a16f576823

17:54 <andrewrk> I probably boke it in e40245570

19:23 <mikdusan> my new favourite error: return error.WIP;

19:30 <andrewrk> mikdusan, nice- I'm also a fan of @panic("TODO")

22:52 <daurnimator> mikdusan: I prefer NYI

22:53 <daurnimator> WIP suggests you'll actually come back to it later ;)

22:54 <daurnimator> though @panic("NYI") is probably better: it doesn't mess up error signatures...... though maybe that's a good thing: if a function has NYI in it's error set you know it isn't ready to use yet....

22:55 <daurnimator> though I more often deal with scenarios where I'm *not allowed to throw*, so the @panic is preferable
