yo! new Zig user here, just started playing around with it yesterday, having lots of fun so far :D
<schme245>
one thing that has me stumped so far: when I try to compile this code
<schme245>
const Player = enum {
<schme245>
Cross,
<schme245>
Circle,
<schme245>
fn asInt(player: Player) i32 {
<schme245>
return switch (player) {
<schme245>
Player.Cross => -1,
<schme245>
Player.Circle => -1,
<schme245>
};
<schme245>
}
<schme245>
};
<schme245>
/zig/tictactoe/tictactoe.zig:14:16: error: unable to infer expression type
<schme245>
return switch (player) {
<schme245>
I get this error ^
<schme245>
I've tried to add some casts and whatnot but to no avail, does anyone know how to make it work?

Is there a way to express that my functions accepts a slice or an array, without the use of var?

schme245: perhaps the return values of the difference cases in the switch are different?
<schme245>
well, one arm returns -1, the other 1, and the function returns i32, so it seems to me that the compiler should be able to figure it out
<donpdonp>
oh i didnt see the switch was in your paste.
<donpdonp>
a function as an enum value? thats new to me

<schme245>
it's pretty neat! it just namedspaces the function so you can call it as `Player.asInt(...)`

<Flaminator>
Schme245 you can use @intCast(i32, -1) or define the values using const one: i32 = 1; const minus_one: i32 = -1; The compiler probably sees the -1 in your code as a comptime_int instead of an i32.
<schme245>
Flaminator: ahh, that explains it, thanks!
<Flaminator>
Pretty sure both of those ways aren't the way it should work though.
<emekankurumeh[m]>
forgot-password: if you are using the latest version of zig, you can just say it accepts a slice and when you need to pass an array just take the address of it. [here's](https://godbolt.org/z/-gg18W) an example.

emekankurumeh[m]: you forgot the squiggly braces inside the warn statements double quotes on lines 16 and 17 in your godbolt example ;). (and probably some '\n's also)

<porky11>
does zig support some type of compile time lists?
<porky11>
I want to do something like that: fn Multivector(comptime C: usize, comptime B: [C]u32, comptime T: type) type { return struct... }
