download, build, and install aur packages with ansible

About

(Forked from: https://gist.github.com/cahna/45bb9eee92c5f1fce66f)

When using ArchLinux, I typically prefer to use an AUR helper like pacaur or yaourt to automate away the process of installing a community package.

Ansible's pacman module is great, but it doesn't support AUR packages or pacman's -U flag. Installing AUR packages with Ansible seemed to be left as an exercise to the user, and since AUR helpers do not come with a fresh Arch install, I created this set of tasks to be a reusable way of installing AUR packages on my Arch hosts.

I should take the time to PR an AUR module for Ansible sometime soon, but this is a nice, resusable submodule for any Arch-based Ansible role.

Example

---
- name: install yaourt on ArchLinux hosts
  hosts: my_archlinux_host_group
  gather_facts: yes
  vars:
    makepkg_nonroot_user: "{{ ansible_ssh_user }}"
  tasks:
    - name: install package-query (a yaourt dependency)
      include: aur/pkg.yml pkg_name=package-query
      
    - name: install yaourt
      include: aur/pkg.yml pkg_name=yaourt

Reccommended Usage

  1. Add this gist as a submodule to your Ansible role or playbook
# Example ./roles directory structure for an existing Ansible playbook with a 'foobar' role 
#   roles/
#     foobar/
#       tasks/
#         aur/          # Source repo added as a submodule (cloned into an `aur` directory)
#           pkg.yml     # Include this file with vars 'pkg_name' and 'makepkg_nonroot_user' to install an AUR package
$ cd ./roles/foobar/tasks
$ git submodule add https://gist.github.com/39ecb1eb1ab8ee1d0ce1.git aur
  1. Now aur/pkg.yml may be included from any task or handler within the foobar role. Given the variables pkg_name and makepkg_nonroot_user, the tasks will validate, download, compile (as the makepkg_nonroot_user user), and install (as root) the pkg_name package.

Tip: Set makepkg_nonroot_user in your group_vars/all file to avoid repeating yourself.
