# gitea-actions

Reusable Gitea Actions for CI workflows.

## Actions

### nix-setup

Installs Nix and sets up Nix store caching for Gitea Actions workflows.

**Features:**
- Uses DeterminateSystems/nix-installer-action for reliable Nix installation
- Caches `/nix/store`, `/nix/var/nix`, and `~/.cache/nix`
- Cache key based on `flake.lock` hash for automatic invalidation
- Each repo gets isolated cache (different flake.lock = different cache)

**Usage:**

```yaml
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: johno/gitea-actions/nix-setup@main
      - run: nix flake check
```

**With custom cache prefix:**

```yaml
- uses: johno/gitea-actions/nix-setup@main
  with:
    cache-name: 'my-project-'
```

**Inputs:**

| Input | Description | Required | Default |
|-------|-------------|----------|---------|
| `cache-name` | Optional cache name prefix for disambiguation | No | `''` |
