ztracy

ztracy v0.13.0 - performance markers for Tracy 0.11.1

Initial Zig bindings created by Martin Wickham

Getting started

Copy ztracy to a subdirectory of your project and add the following to your build.zig.zon .dependencies:

    .ztracy = .{ .path = "libs/ztracy" },

Then in your build.zig add:

pub fn build(b: *std.Build) void {
    const exe = b.addExecutable(.{ ... });

    const ztracy = b.dependency("ztracy", .{
        .enable_ztracy = true,
        .enable_fibers = true,
    });
    exe.root_module.addImport("ztracy", ztracy.module("root"));
    exe.linkLibrary(ztracy.artifact("tracy"));
}

Now in your code you may import and use ztracy. To build your project with Tracy enabled run:

zig build -Dztracy-enable=true

const ztracy = @import("ztracy");

pub fn main() !void {
    {
        const tracy_zone = ztracy.ZoneNC(@src(), "Compute Magic", 0x00_ff_00_00);
        defer tracy_zone.End();
        ...
    }
}

Async "Fibers" support

Tracy has support for marking fibers (also called green threads, coroutines, and other forms of cooperative multitasking). This support requires an additional option passed through when compiling the Tracy library, so:

    ...
    const optimize = b.standardOptimizeOption(.{});
    const target = b.standardTargetOptions(.{});

    const ztracy_pkg = ztracy.package(b, target, optimize, .{
        .options = .{ .enable_ztracy = true, .enable_fibers = true },
    });

    ztracy_pkg.link(exe);
