## Development

### System Dependencies

This project has `flake.nix` for development environment setup.
To start development shell, run:

```
nix develop
```

To develop without [Nix](https://nixos.org/) [Flakes](https://wiki.nixos.org/wiki/Flakes), install these softwares manually:

- Zig compiler v0.15
- Vala compiler v0.56
- pkg-config
- Runtime dependencies

### Running application

```
zig build run
```

### Enable debug logging

Add `Plac` to `G_MESSAGES_DEBUG` environment variable:

```
G_MESSAGES_DEBUG=Plac zig build run
```

### Code Formatting

This project uses [treefmt](https://treefmt.com) as a code formatter frontend.
In addition to system dependencies, you need these formatter softwares:

- dprint
- Uncrustify
- nixfmt

After installing required softwares, you can format source code by:

```
treefmt
```

### Build Flatpak bundle

This project provides Zig build script for building Flatpak single-file bundle.
Enter `nix develop .#flatpak` or install `flatpak` and `flatpak-builder`, then run:

```
zig build flatpak
```

This will produce `jp.pocka.plac.gtk-adwaita.flatpak` inside `zig-out` directory.

### License Checking
