Packer is a wrapper for Arch linux's package manager Pacman and Arch User Repository (AUR). Pacman can not install packages from AUR. This tool helps you do just that.
Install Requirements
:$ sudo pacman -S base-devel fakeroot jshon expac git
Get PKGBUILD
:$ wget https://aur.archlinux.org/cgit/aur.git/plain/PKGBUILD?h=packer
Rename the downloaded file.
:$ mv PKGBUILD\?h\=packer PKGBUILD
Run makepkg on the PKGBUILD
:$ makepkg
Install the Package
:$ sudo pacman -U packer-*.pkg.tar.xz
Usage is similar to Pacman
To install a package from AUR:
:$ packer -S <package>
To update all AUR packages. (This also updated packages installed by Pacman).
:$ packer -Syu
Note: Always run packer as a regular user. If packer needs elevated privileges, it will ask for authentication.
