-# Ansible AUR helper
+# Ansible Collection - kewlfft.aur
-Ansible module to use some Arch User Repository (AUR) helpers as well as makepkg.
 
-The following helpers are supported and automatically selected in the order they are listed:
+## Description
-- [aurman](https://github.com/polygamma/aurman)
+
-- [pacaur](https://github.com/rmarquis/pacaur)
+This collection includes an Ansible module to manage packages from the AUR.
+
+## Installation
+
+### Install the `kewlfft.aur` collection from Ansible Galaxy
+
+To install this collection from Ansible Galaxy, run the following command:
+
+```shell
+ansible-galaxy collection install kewlfft.aur
+```
+
+Alternatively, you can include the collection in a `requirements.yml` file and then run `ansible-galaxy collection install -r requirements.yml`. Here is an example of `requirements.yml` file:
+
+```yaml
+collections:
+  - name: kewlfft.aur
+```
+
+### Install the `kewlfft.aur` collection from the AUR
+
+The `kewlfft.aur` collection is also available in the AUR as the [`ansible-collection-kewlfft-aur`](https://aur.archlinux.org/packages/ansible-collection-kewlfft-aur/) package.
+
+### Install the `kewlfft.aur` collection locally for development
+
+If you want to test changes to the source code, run the following commands from the root of this git repository to locally build and install the collection:
+
+```shell
+ansible-galaxy collection build --force
+ansible-galaxy collection install --force "./kewlfft-aur-$(cat galaxy.yml | grep version: | awk '{print $2}').tar.gz"
+```
+
+### Install the `aur` module as a local custom module
+
+Alternatively, you may manually install the `aur` module itself as a [local custom module](https://docs.ansible.com/ansible/latest/dev_guide/developing_locally.html) instead of installing the module through the `kewlfft.aur` Ansible collection. However, it is recommended to use `kewlfft.aur` collection unless you have a good reason not to. Here are the commands to install the `aur` module as a local custom module:
+
+```shell
+# Create the user custom module directory
+mkdir ~/.ansible/plugins/modules
+
+# Install the aur module into the user custom module directory
+curl -o ~/.ansible/plugins/modules/aur.py https://raw.githubusercontent.com/kewlfft/ansible-aur/master/plugins/modules/aur.py
+```
+
+## kewlfft.aur.aur Module

+
+#### Note
 
-### Note
 * Either *name* or *upgrade* is required, both cannot be used together.
-* *skip_installed* cannot be used with *upgrade*.
 * In the *use*=*auto* mode, makepkg is used as a fallback if no known helper is found.
 
-## Installing
+### Usage
-1. Clone the *ansibe-aur* repository in your playbook custom-module directory:
-```
-mkdir --parents library
-cd library
-git clone git@github.com:kewlfft/ansible-aur.git
-```
 
-2. Link the script to `library/aur`:
+#### Notes
-```
-ln --symbolic ansible-aur/aur.py aur
-```
 
-## Usage
+* The scope of this module is installation and update from the AUR; for package removal or for updates from the repositories, it is recommended to use the official *pacman* module.
-### Note
+* The *--needed* parameter of the helper is systematically used, it means if a package is up-to-date, it is not built and reinstalled.
-* This module aims to cover the AUR, for package removal or system upgrade with the repositories, it is recommended to use the official *pacman* module,
-* A package is reinstalled only if an update is available, using the *--needed* parameter, except for *yay* which does not support it and systematically reinstalls.
 
-### Examples
+#### Create the "aur_builder" user
-Use it in a task, as in the following examples:
-```
-# Install trizen using makepkg, skip if trizen is already installed
-- aur: name=trizen use=makepkg skip_installed=true
-  become: yes
-  become_user: aur_builder
 
-# Install package_name using the first known helper found
+While Ansible expects to SSH as root, makepkg or AUR helpers do not allow executing operations as root, they fail with "you cannot perform this operation as root". It is therefore recommended to create a user, which is non-root but has no need for password with pacman in sudoers, let's call it *aur_builder*.
-- aur: name=package_name
-  ...
 
-# Install package_name_1 and package_name_2 using trizen
+This user can be created in an Ansible task with the following actions:
-- aur:
-    use: trizen
-    name:
-      - package_name_1
-      - package_name_2
-  ...
 
-# Upgrade - using pacaur
+```yaml
-- aur: upgrade=yes use=pacaur
+- name: Create the `aur_builder` user
-  ...
+  ansible.builtin.user:
-```
-
-### Create the "aur_builder" user
-While Ansible expects to SSH as root, AUR helpers do not allow executing operations as root, they all fail with "you cannot perform this operation as root". It is therefore recommended to create a user, that we will call for example *aur_builder*, that has no need for password with pacman in sudoers.
-This can be done in Ansible with the following actions:
-```
-- user:
     name: aur_builder
+    create_home: yes
     group: wheel
-- lineinfile:
+
+- name: Allow the `aur_builder` user to run `sudo pacman` without a password
+  ansible.builtin.lineinfile:
     path: /etc/sudoers.d/11-install-aur_builder
     line: 'aur_builder ALL=(ALL) NOPASSWD: /usr/bin/pacman'
     create: yes
     validate: 'visudo -cf %s'
 ```
+
+#### Fully Qualified Collection Names (FQCNs)
+
+In order to use an Ansible module that is distributed in a collection, you must use its FQCN. This corresponds to "the full definition of a module, plugin, or role hosted within a collection, in the form `namespace.collection.content_name`" ([Source](https://github.com/ansible-collections/overview#terminology)). In this case, the `aur` module resides in the `aur` collection which is under the `kewlfft` namespace, so its FQCN is `kewlfft.aur.aur`.
+
+Please note that this does not apply if you installed the `aur` module as a local custom module. Due to the nature of local custom modules, you can simply use the module's short name: `aur`.
+
+#### Examples
+
+Use it in a task, as in the following examples:
+
+```yaml
+# This task uses the module's short name instead of its FQCN (Fully Qualified Collection Name).
+# Use the short name if the module was installed as a local custom module.
+# Otherwise, if it was installed through the `kewlfft.aur` collection, this task will fail.
+- name: Install trizen using makepkg if it isn't installed already
+  aur:
+    name: trizen
+    use: makepkg
+    state: present
+  become: yes
+  become_user: aur_builder
+
+# This task uses the `aur` module's FQCN.
+- name: Install trizen using makepkg if it isn't installed already
+  kewlfft.aur.aur:
+    name: trizen
+    use: makepkg
+    state: present
+  become: yes
+  become_user: aur_builder
+
+- name: Install package_name_1 and package_name_2 using yay
+  kewlfft.aur.aur:
+    use: yay
+    name:
+      - package_name_1
+      - package_name_2
+
+# Note: Dependency resolution will still include repository packages.
+- name: Upgrade the system using yay, only act on AUR packages.
+  kewlfft.aur.aur:
+    upgrade: yes
+    use: yay
+    aur_only: yes
+
+# Skip if it is already installed
+- name: Install gnome-shell-extension-caffeine-git using pikaur and a local PKGBUILD.
+  kewlfft.aur.aur:
+    name: gnome-shell-extension-caffeine-git
+    use: pikaur
+    local_pkgbuild: {{ role_path }}/files/gnome-shell-extension-caffeine-git
+    state: present
+  become: yes
+  become_user: aur_builder
+```
