I am using the raylib library wrapper https://github.com/Not-Nik/raylib-zig
the signatue is pub fn drawText(text: [:0]const u8, posX: i32, posY: i32, fontSize: i32, color: Color) void
I am trying to put a []const u8 as the text part but it has no sentinel
sinful snow
Where does the []const u8 you're trying to use come from?

from a different part of my program

a string literal is a null-terminated string

i created a app-like class and now im trying to add visuals with raylib
idle frigate
you could use a string literal
flint plaza
what do you mean?

from a different part of my program
I mean how is it constructed
idle frigate
const hello_world = "hello world";
do you know what this is?
flint plaza
why default to null terminated?? doesnt zig avoid that
idle frigate
not for literals
flint plaza
isnt [:0] only null terminated
idle frigate
`const hello_world = "hello world";`
do you know what this is?
print the type info. its a literal
i use raylib myself, it works

String literals are constant single-item Pointers to null-terminated byte arrays. The type of string literals encodes both the length, and the fact that they are null-terminated, and thus they can be coerced to both Slices and Null-Terminated Pointers. Dereferencing string literals converts them to Arrays.

that somewhat makes sense i guess

zig APIs generally don't require null termination, but zig string literals are null terminated because it's convenient for passing them into C. and if you pass it into zig instead it'll use the known length instead of looking for the terminator.

ah i remeber reading its both null terminated and the length is stored at the same time
is this not a string literal? const str: []u8 const = "hello world;
sinful snow
It is, but it's being coerced to a u8 slice
Just change the type to the one you need and it'll coerce to that instead
sinful snow
The type that the function you need to pass it to accepts
flint plaza
ok i guess im overcomplicating, thanks that worked
