I have a project with two files:
pub const Foo = struct {
i: u32,
};
const std = @import("std");
usingnamespace @import("foo.zig");
pub fn main() !void {
const foo = Foo { .i = 42 };
std.debug.print("{}", .{ foo.i });
}
I would expect this to compile, but I'm getting this error:
const foo = Foo { .i = 42 };```
Why isn't `Foo` visible in `main.zig`?

Decls have to be pub to be exposed through @import

Oh, of course, sorry. That was a typo, even with pub it doesn't work. Edited the original post.

usingnamespace makes the decls available when qualified. you would have to use @This().Foo for your example to work.

I see
ruby osprey
there's no way to use decls from another file unqualified
except making new names in your scope
idle basalt
Is this the intended behavior?
The docs for usingnamespace aren't super clear, so I mostly guessed what it would do coming from C++
ruby osprey
an identifier in scope of more than one usingnamespace forces all of them to be resolved, in order to make sure there are no name conflicts. However, using a.b syntax means only the includenamespace declarations that apply to a must be resolved. With incremental compilation, having an identifier force an unrelated usingnamespace to be resolved creates a dependency between these two things.
it's a bit unintuitive but it makes sense as a decision to me
idle basalt
Yeah, it makes sense actually
From the compilers point of view at least 🙂
I need to do some thinking on how to to organize a larger project. I'm used to working with many small files organized into folders, where the folders map to namespaces. It seems like that approach won't work very well in Zig.

you can make that work. Many stdlib modules are organised as such
it just means you can't import identifiers en-masse, you can still do const assert = std.debug.assert;

This confused me too.
