#
# 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_remote
# Python 3:
# ansible-test integration -v --docker fedora28 --docker-privileged --allow-unsupported --python 3.6 flatpak_remote
#
# 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_remote
short_description: Manage flatpak repository remotes
description:
- Allows users to add or remove flatpak remotes.
- The flatpak remotes concept is comparable to what is called repositories in other packaging
formats.
- Currently, remote addition is only supported via I(flatpakrepo) file URLs.
- Existing remotes will not be updated.
- See the M(flatpak) module for managing flatpaks.

flatpakrepo_url:
description:
- The URL to the I(flatpakrepo) file representing the repository remote to add.
- When used with I(state=present), the flatpak remote specified under the I(flatpakrepo_url)
is added using the specified installation C(method).
- When used with I(state=absent), this is not required.
- Required when I(state=present).

name:
description:
- The desired name for the flatpak remote to be registered under on the managed host.
- When used with I(state=present), the remote will be added to the managed host under
the specified I(name).
- When used with I(state=absent) the remote with that name will be removed.
