### Run 5s Timer in C with Libxev

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Example of using libxev in C to set up and run a 5-second timer. Includes necessary headers and callback function.

```c
#include <stddef.h>
#include <stdio.h>
#include <xev.h>

xev_cb_action timerCallback(xev_loop* loop, xev_completion* c, int result, void *userdata) {
    return XEV_DISARM;
}

int main(void) {
    xev_loop loop;
    if (xev_loop_init(&loop) != 0) {
        printf("xev_loop_init failure\n");
        return 1;
    }

    xev_watcher w;
    if (xev_timer_init(&w) != 0) {
        printf("xev_timer_init failure\n");
        return 1;
    }

    xev_completion c;
    xev_timer_run(&w, &loop, &c, 5000, NULL, &timerCallback);

    xev_loop_run(&loop, XEV_RUN_UNTIL_DONE);

    xev_timer_deinit(&w);
    xev_loop_deinit(&loop);
    return 0;
```

### Run 5s Timer in Zig with Libxev

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Example of using libxev in Zig to set up and run a 5-second timer. Requires importing the 'xev' module.

```zig
const xev = @import("xev");

pub fn main() !void {
    var loop = try xev.Loop.init(.{});
    defer loop.deinit();

    const w = try xev.Timer.init();
    defer w.deinit();

    // 5s timer
    var c: xev.Completion = undefined;
    w.run(&loop, &c, 5000, void, null, &timerCallback);

    try loop.run(.until_done);
}

fn timerCallback(
    userdata: ?*void,
    loop: *xev.Loop,
    c: *xev.Completion,
    result: xev.Timer.RunError!void,
) xev.CallbackAction {
   _ = userdata;
   _ = loop;
   _ = c;
   _ = result catch unreachable;
   return .disarm;
}
```

### Render Man Pages with scdoc

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Command to render libxev man pages after building with `zig build -Dman-pages`. Requires `scdoc` to be installed.

```bash
man zig-out/share/man/man7/xev.7
```

--------------------------------

### Run WASI Tests with Wasmtime

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Execute tests for the WebAssembly System Interface (WASI) target. Requires wasmtime to be installed and configured.

```sh
$ zig build test -Dtarget=wasm32-wasi -Dwasmtime
...
```

--------------------------------

### Cross-Compile Tests for macOS

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Build and compile tests for a different platform, such as macOS on ARM architecture, from a Linux host. This involves specifying the target and enabling test installation.

```sh
$ zig build -Dtarget=aarch64-macos -Dinstall-tests
...

$ file zig-out/bin/xev-test
zig-out/bin/xev-test: Mach-O 64-bit arm64 executable
```

--------------------------------

### Zig Build Configuration for Libxev

Source: https://github.com/mitchellh/libxev/blob/main/README.md

Configuration for `build.zig.zon` to include libxev as a dependency using the Zig package manager. Replace `<git-ref-here>` with the desired Git reference.

```zig
.{
    .name = "my-project",
    .version = "0.0.0",
    .dependencies = .{
        .libxev = .{
            .url = "https://github.com/mitchellh/libxev/archive/<git-ref-here>.tar.gz",
            .hash = "12208070233b17de6be05e32af096a6760682b48598323234824def41789e993432c",
        },
    },
}
```
