YAP — Yet Another Packager MCP server

YAP — Yet Another Packager

YAP builds native packages for multiple GNU/Linux distributions from a single PKGBUILD specification. Write your package once; get .deb, .rpm, .apk, and .pkg.tar.zst out. All builds run in isolated OCI containers (Docker or Podman).

Features

• Multi-format output: DEB (Debian/Ubuntu), RPM (Fedora/RHEL/Rocky/openSUSE), APK (Alpine), TAR.ZST (Arch)
• Container isolation: reproducible builds, no host contamination, Docker and Podman supported
• PKGBUILD-based: familiar Arch Linux syntax extended with distribution and architecture overrides
• Cross-compilation: build for a different architecture than your host
• Dependency-aware builds: sequential by default; opt-in parallel topo-sort via --parallel
• Package signing: APK RSA + DEB/RPM/Pacman GPG (no gpg binary required)
• SBOM generation: CycloneDX 1.5 and SPDX 2.3 sidecars
• Per-format compression: zstd/gzip/xz for DEB and RPM
• Changelog support: changelog PKGBUILD field renders to native format per distro
• Pacman scriptlets: full 6-hook lifecycle (pre/post install/upgrade/remove)
• Structured logging: slog-based, tree rendering for long lines, zero external UI deps

Installation

One-liner (Linux/macOS, amd64/arm64):

curl -fsSL https://raw.githubusercontent.com/M0Rf30/yap/main/scripts/install.sh | sh

Pin a version or install only one tool:

curl -fsSL https://raw.githubusercontent.com/M0Rf30/yap/main/scripts/install.sh \
  | sh -s -- --version v2.1.3 --tool yap

Manual download:

wget https://github.com/M0Rf30/yap/releases/latest/download/yap_Linux_x86_64.tar.gz
tar -xzf yap_Linux_x86_64.tar.gz
sudo mv yap /usr/local/bin/
yap version

Build from source

git clone https://github.com/M0Rf30/yap.git
cd yap
make build
sudo mv yap /usr/local/bin/

Requires Docker or Podman:

# Docker
sudo systemctl enable --now docker && sudo usermod -aG docker $USER

# Podman
sudo systemctl enable --now podman

Quick start

1. Project structure

Create yap.json:

{
  "name": "My Package",
  "description": "A sample package built with YAP",
  "buildDir": "/tmp/yap-build",
  "output": "artifacts",
  "projects": [
    { "name": "my-package" }
  ]
}

2. PKGBUILD

Create my-package/PKGBUILD:

pkgname=my-package
pkgver=1.0.0
pkgrel=1
pkgdesc="My awesome application"
arch=('x86_64')
license=('GPL-3.0')
url="https://github.com/user/my-package"
makedepends=('gcc' 'make')
source=("https://github.com/user/my-package/archive/v${pkgver}.tar.gz")
sha256sums=('SKIP')

build() {
    cd "${srcdir}/${pkgname}-${pkgver}"
    make
}

package() {
    cd "${srcdir}/${pkgname}-${pkgver}"
    install -Dm755 my-package "${pkgdir}/usr/bin/my-package"
    install -Dm644 README.md "${pkgdir}/usr/share/doc/${pkgname}/README.md"
}

3. Build

# Auto-detect host distro from /etc/os-release
yap build .

# Specific distribution
yap build ubuntu-jammy .
yap build fedora-38 /path/to/project
yap build --cleanbuild --no-makedeps ubuntu-jammy .

4. Output

artifacts/
├── my-package_1.0.0-1_amd64.deb
├── my-package-1.0.0-1.x86_64.rpm
├── my-package-1.0.0-r1.apk
└── my-package-1.0.0-1-x86_64.pkg.tar.zst
