# ATTENTION CONTRIBUTORS!
#
# TL;DR: Run this module's integration tests manually before opening a pull request
#
# Long explanation:
# The integration tests for this module are currently NOT run on the Ansible project's continuous
# delivery pipeline. So please: When you make changes to this module, make sure that you run the
# included integration tests manually for both Python 2 and Python 3:
#
#   Python 2:
#       ansible-test integration -v --docker fedora28 --docker-privileged --allow-unsupported --python 2.7 flatpak
#   Python 3:
#       ansible-test integration -v --docker fedora28 --docker-privileged --allow-unsupported --python 3.6 flatpak
#
# Because of external dependencies, the current integration tests are somewhat too slow and brittle
# to be included right now. I have plans to rewrite the integration tests based on a local flatpak
# repository so that they can be included into the normal CI pipeline.

module: flatpak
version_added: '2.6'
short_description: Manage flatpaks
description:
- Allows users to add or remove flatpaks.
- See the M(flatpak_remote) module for managing flatpak remotes.
author:
- John Kwiatkoski (@JayKayy)
- Alexander Bethke (@oolongbrothers)
requirements:
- flatpak
options:
  executable:
    description:
    - The path to the C(flatpak) executable to use.
    - By default, this module looks for the C(flatpak) executable on the path.
    default: flatpak
  method:
    description:
    - The installation method to use.
    - Defines if the I(flatpak) is supposed to be installed globally for the whole C(system)
      or only for the current C(user).
    choices: [ system, user ]
    default: system
  name:
    description:
    - The name of the flatpak to manage.
    - When used with I(state=present), I(name) can be specified as an C(http(s)) URL to a
      C(flatpakref) file or the unique reverse DNS name that identifies a flatpak.
    - When suppying a reverse DNS name, you can use the I(remote) option to specify on what remote
      to look for the flatpak. An example for a reverse DNS name is C(org.gnome.gedit).
    - When used with I(state=absent), it is recommended to specify the name in the reverse DNS
      format.
    - When supplying an C(http(s)) URL with I(state=absent), the module will try to match the
      installed flatpak based on the name of the flatpakref to remove it. However, there is no
      guarantee that the names of the flatpakref file and the reverse DNS name of the installed
      flatpak do match.
    required: true
  remote:
    description:
    - The flatpak remote (repository) to install the flatpak from.
    - By default, C(flathub) is assumed, but you do need to add the flathub flatpak_remote before
      you can use this.
    - See the M(flatpak_remote) module for managing flatpak remotes.
    default: flathub
  state:
    description:
    - Indicates the desired package state.
    choices: [ absent, present ]
    default: present
