⚠️ Project Archived ⚠️. This project is archived. I used this for a few real projects since 2021 and it was stable, but I've since moved onto using libxev so I'm no longer maintaining the libuv bindings.

zig-libuv

zig-libuv contains a build.zig that can build libuv using Zig and also contains a package with Zig bindings. Both can be used together or separately. Building libuv with Zig enables easy cross-compilation. The bindings allow you to consume libuv easily whether it is built with Zig or not.

Example

There are lots of examples in the tests for each individual handle type. Below is an example of using a timer, copied exactly from the tests:

var loop = try Loop.init(testing.allocator);
defer loop.deinit(testing.allocator);

var timer = try init(testing.allocator, loop);
defer timer.deinit(testing.allocator);

var called: bool = false;
timer.setData(&called);
try timer.start((struct {
    fn callback(t: *Timer) void {
        t.getData(bool).?.* = true;
        t.close(null);
    }
}).callback, 10, 1000);

_ = try loop.run(.default);

try testing.expect(called);

Usage

To build libuv:

const libuv = @import("path/to/zig-libuv/build.zig");

pub fn build(b: *std.build.Builder) !void {
    // ...

    const exe = b.addExecutable("my-program", "src/main.zig");
    _ = libuv.link(b, exe);
}

To use the Zig bindings, add the package:

exe.addPackage(libuv.pkg);
