Flatpak packaging

Building Flatpak

To build flatpak package, you will need flatpak, flatpak-builder, and
KDE 5.12 runtime with SDK. flatpak-builder is usually available from
the same repository as flatpak. See https://flatpak.org/setup/ for
setting it up. To install runtimes (adjust as needed if you prefer
system-wide installation):

flatpak install --user flathub org.kde.Platform//5.12 org.kde.Sdk//5.12

To build, run from the root of the project:

flatpak-builder --repo=build/flatpak/repo --force-clean build/flatpak/build packaging/flatpak/mirage.flatpak.yaml

To create bundle, run

flatpak build-bundle build/flatpak/repo build/mirage.flatpak io.github.mirukana.mirage

Then you can install it with

flatpak install --user build/mirage.flatpak

To run, either use your desktop environment or command line:

flatpak run io.github.mirukana.mirage

Manifest

The manifest can be created using the included scripts, as described
below. Please note it is intended to be done by the maintainers
only. In particular, there could be some unexpected issues exposed by
updates in Python modules that have to be resolved.

The manifest has to be updated by maintainers when the dependencies of
Mirage change, or some updates in used Python modules are desired.

The Flatpak packaging manifest is generated by running
generate-flatpak-script.sh, which
uses mirage.flatpak.base.yaml and replaces the
marked placeholder with Python dependencies.

This script requires libolm to be installed on the development PC, as it
will create Python virtual environment and install all the requirements in it.

Note that the Python dependencies are taken from
requirements.flatpak.txt and the
project root's requirements.txt.

In addition, the list of ignored packages is in
generate-flatpak-script.sh.
