# Mach: game engine & graphics toolkit for the future

Written in [Zig](https://ziglang.org/), Mach is for creating games, graphical applications, and desktop/mobile apps:

- Data-driven, tooling oriented
- Composable
- Competitive with Unity and Unreal in spirit (a fully fledged editor in the future, etc.)

## Cross-platform graphics in ~60 seconds

```sh
git clone https://github.com/hexops/mach
cd mach/
zig build run-example-boids
```

Cross-platform graphics, a unified shader language & compute shaders.

(Requires [zig 0.10.x](https://ziglang.org/) | [known issues](https://github.com/hexops/mach/blob/main/doc/known-issues.md#known-issues))

No, it’s not Tom from myspace - it’s me, @slimsag! It’s taken [almost a year to get here](https://devlog.hexops.com/2022/mach-v0.1-zig-graphics-in-60s) - staring at broken CI pipelines, C++ compiler errors, [buying hardware](https://twitter.com/slimsag/status/1507506138144681986) to test every OS+arch possible, and more.

There are few things in life that I am more serious about than this work. I dedicate ~48 hours/week to my dayjob, and ~50h/week to Zig building Mach and running [zigmonthly.org](https://zigmonthly.org). After three years of aggressively pushing for progress in this exact way, [I have no plans to slow down anytime soon.](https://devlog.hexops.com/2021/i-write-code-100-hours-a-week)

## Supported platforms

Mach is still early stages, so far we have support for building from the following OS to the following targets:

- ✅ Tested and verified via CI.
- ✔️ Should work, not tested via CI yet.
- 🏃 Planned or in progress.
- ⚠️ Implemented, but has known issues (e.g. bugs in Zig.)

## Libraries

Mach has many libraries you can use for game development in Zig - you don't have to use the entire engine. All our libraries aim to have the same zero-fuss installation, cross compilation, and platform support:

- [mach-glfw](https://github.com/hexops/mach-glfw): Ziggified GLFW bindings with 100% API coverage
- [mach-gpu-dawn](https://github.com/hexops/mach-gpu-dawn): Google's Dawn WebGPU implementation, cross-compiled with Zig into a single static library
- [mach-system-sdk](https://github.com/hexops/mach-system-sdk): More libraries for cross-compilation with Zig

## Contributing

Mach is maintained as a monorepo. When changes are merged to this repository, we use some git-fu to pick out the commits to subdirectories and push them to sub-repositories automagically. Changes to the `glfw/` directory in this repository get pushed to the separate [mach-glfw](https://github.com/hexops/mach-glfw) repository after being merged here, for example.

Please prefix commits / pull requests with the project name (`glfw: fix an issue`, `gpu: fix an issue`, `examples: fix an issue`, etc.) and if possible only one project per commit. If you don't know how to do this, no worries, we can help - just send your PR anyway!
