Using Zig 0.11 in 2023

Zig has a package manager

As of this writing, October 6 2023, the package manager is currently being worked on for the next release: 0.12.

Here are some relevant Github links detailing that work:

“To use a package that’s been prepared for the new Zig package manager, you just need to list it in the dependencies section.”

Zon. It uses files such as build.zig.zon which contains a zig anonymous struct. Example:

1
// because zon file is really just a zig struct
2
// comments are really done in the same way using 2 forward slashes
3
.{
4
    // the name of your project
5
    .name = "my-wtf-project",
6
    // the version of your project
7
    .version = "0.0.1",
8

9
    // the actual packages you need as dependencies of your project
10
    .dependencies = .{
11
        // the name of the package
12
        .zap = .{
13
            // the url to the release of the module
14
            .url = "https://github.com/zigzap/zap/archive/refs/tags/v0.1.7-pre.tar.gz",
15
            // the hash of the module, this is not the checksum of the tarball
16
            .hash = "1220002d24d73672fe8b1e39717c0671598acc8ec27b8af2e1caf623a4fd0ce0d1bd",

        },

    }
