Install instruction

[eunier]

Hi, thanks for this work. Could you add install instruction for the zig nooby like myself, thanks!

I figured out be looking into your build.zig file.

Path: deps/... in my case:

    const ecs_module = b.addModule("zig-ecs", .{
        .root_source_file = b.path("deps/zig-ecs/src/ecs.zig"),
        .optimize = optimize,
        .target = target,
    });

    exe.root_module.addImport("ecs", ecs_module);

I still think the request could be useful.

Hi, I added it like this:

    const ecs_dep = b.dependency("entt", .{
        .target = target,
        .optimize = optimize,
    });
    const ecs = ecs_dep.module("zig-ecs");
    exe.root_module.addImport("ecs", ecs);

Although I had to look up the name of the module for b.dependency("entt", ... as well as for ecs_dep.module("zig-ecs"). I think this is a deeper problem with zig's dependency system, but yeah it's always nice with some installation instructions.

I should have read the comment above more carefully. Here is my full process for using zig fetch:

1. Fetch using zig

zig fetch --save=ecs git+https://github.com/prime31/zig-ecs

This should create something similar to this in build.zig.zon:

...
    .dependencies = .{
        .ecs = .{
            .url = "git+https://github.com/prime31/zig-ecs#d3ae70ef6185b2e0269d62a57608bfce2567c102",
            .hash = "1220949709178b133c4d7f6ddf87fa575a9f2e9afe545a39aafdc8c89e6abbe83412",
        },
    },
...

2. Now you can use it in build.zig:

    const ecs_dependency = b.dependency("ecs", .{ .target = target, .optimize = optimize }).module("zig-ecs");
    exe.root_module.addImport("ecs", ecs_dependency);

3. Use it in your project

const ecs = @import("ecs");
