# Arch build system

Tools for compiling packages from source into .pkg.tar.zst archives for use with [pacman](pacman).
Each package has a git repository that includes a PKGBUILD and sometimes other files. Run `makepkg` to download, compile and package the sources. Then you can use pacman to install them.

# PKGBUILD
A PKGBUILD file is just a bash script that specifies how to compile and package something. It's a collection of functions and variables parsed by makepkg.

Check out examples at `/usr/share/pacman`.
Use `namcap` to check for mistakes.

# makepkg
makepkg is a shell utility that reads the PKGBUILD and invokes the necesarry commands

You can speed up compilation by setting build directory in tmpfs with `BUILDDIR=/tmp/makepkg makepkg`


# Build packages from source
An outline:
1. Get PKGBUILD
	* Use `pkgctl repo clone <pkgname>`
	* Use git: `git clone https://gitlab.archlinux.org/archlinux/packaging/packages/pkgname.git`
2. Build package
	* Copy the build dir and edit the PKGBUILD if needed
	* Build with makepkg
