# Omarchy Package Repository

Build system for the Omarchy Package Repository. Builds PKGBUILDs from local sources and AUR, signs them, and syncs to production.

**Multi-Architecture**: Supports both x86_64 and aarch64 (ARM64).

## Prerequisites
### aarch64 Builds (Optional)

To build ARM64 packages on x86_64, enable QEMU emulation:

```bash
# Run after each reboot
docker run --privileged --rm tonistiigi/binfmt --install arm64

# Verify
docker run --rm --platform linux/arm64 alpine:latest uname -m
# Should output: aarch64
```

**Note**: aarch64 builds use QEMU and slower than native x86_64 builds.

## Quick Start

### Complete Workflow

```bash
# Build, sign, promote, clean, and sync
bin/repo release

# Single package
bin/repo release --package omarchy-nvim

# ARM64
bin/repo release --arch aarch64 --package omarchy-nvim
```

### Step-by-Step

```bash
bin/repo build                          # Build (unsigned)
bin/repo sign                           # Sign packages
bin/repo promote                        # Copy to production
bin/repo clean                          # Remove old versions
bin/repo sync pkgs.omarchy.org/x86_64   # Sync to remote
```

## Commands

### Build

```bash
bin/repo build                                   # All packages (x86_64)
bin/repo build --package yay cursor-bin          # Specific packages
bin/repo build --arch aarch64                    # ARM64
```

**Output**: Unsigned `.pkg.tar.zst` in `build-output/`

### Sign

```bash
bin/repo sign
```

Fetches GPG key from 1Password or environment, signs all packages in `build-output/`.

### Promote

```bash
bin/repo promote                    # Copy to production
bin/repo promote --arch aarch64     # ARM64
bin/repo promote --dry-run          # Preview
```

Copies signed packages from `build-output/` → `pkgs.omarchy.org/`.

### Clean

```bash
bin/repo clean                      # Keep 2 versions
bin/repo clean --keep 3             # Keep 3 versions
bin/repo clean --dry-run            # Preview
```

Removes old versions, updates database.

### Sync

```bash
bin/repo sync pkgs.omarchy.org/x86_64                    # Production
bin/repo sync pkgs.omarchy.org/aarch64                   # ARM64
bin/repo sync pkgs.omarchy.org/x86_64 --skip-prod-check # No confirmation
```

Syncs to remote server using rclone.

### Other

```bash
bin/repo list                       # List packages
bin/repo remove <package>           # Remove package
bin/repo update                     # Update database
```

```

## Adding Packages

### From AUR

```bash
# Add to sync list
echo "package-name" >> build/packages/omarchy-aur.packages

# Sync PKGBUILD
bin/sync-aur package-name

# Build and release
bin/repo release --package package-name
```

#### Local Patches for AUR Packages

Create `pkgbuilds/package-name/patches/*.patch` to maintain modifications across AUR syncs:

```bash
cd pkgbuilds/package-name
# Make changes
git diff > patches/my-fix.patch
# Next sync will auto-apply patches
```

### Custom Package

```bash
mkdir pkgbuilds/my-package
# Add PKGBUILD and files
bin/repo release --package my-package
```

## Architecture-Specific Notes

### x86_64
- Native builds (fast)
- Mirrors: mirror.omarchy.org, rackspace, pkgbuild.com

### aarch64
- QEMU emulation required on x86_64 hosts (slower)
- Uses Arch Linux ARM repositories
- Additional repos: `[alarm]`, `[aur]`
- Same workflow, just add `--arch aarch64`

### Building for Both Architectures

```bash
# Build x86_64
bin/repo release --package myapp

# Build aarch64
bin/repo release --arch aarch64 --package myapp

# Sync both
bin/repo sync pkgs.omarchy.org/x86_64
bin/repo sync pkgs.omarchy.org/aarch64
```

## Dependency Resolution

The build system automatically handles inter-package dependencies:

1. Parses `depends=()` and `makedepends=()` from PKGBUILDs
2. Builds in correct order
3. Makes newly-built packages available via temporary `[omarchy-build]` repo

Example: If `aether` depends on `hyprshade`, `hyprshade` is built first.

## Version Management

Packages are only rebuilt if:
- PKGBUILD version is newer than repository version
- Package doesn't exist in production
