panda3d-flatpak 0.1.0

Flatpak support for Panda3D

NOTE ==========================================================================

This works on Linux only.

INSTALLATION ==================================================================

pip install panda3d-flatpak

USAGE =========================================================================

In your setup.py file, add the following:

from direct.dist.commands import bdist_apps
from p3d_flatpak import FlatpakBuilder

class BDistAppsCmd(bdist_apps):
    def run(self):
        bdist_apps.run(self)
        bld = FlatpakBuilder(
            self,
            'com.yourCompany.YourProject',
            '/home/you/path/to/flatpak_repo',
            'D43B...B5',
            '/home/you/path/to/gpg',
	    'http://www.yourdomain.org/flatpak')
        bld.build()

setup(
    ...
    cmdclass={"bdist_apps": BDistAppsCmd},
    ... )

This article
(https://blogs.gnome.org/alexl/2017/02/10/maintaining-a-flatpak-repository/)
contains a section which explains how to create GPG keys for signing Flatpak
repos.

UPDATES =======================================================================

If you built a Flatpak repo, and later you modify your code and execute 'python
setup.py bdist_apps' again, your Flatpak repo will be updated. So, your users
can do their 'flatpak update' command to update your project.

EXAMPLE =======================================================================

Let's build a Flatpak repository for the Panda3D's Asteroids example.

First of all, create your GPG key (look at the article cited earlier).

Modify the file setup.py
(https://github.com/panda3d/panda3d/blob/master/samples/asteroids/setup.py)
adding these lines:

from direct.dist.commands import bdist_apps
from p3d_flatpak import FlatpakBuilder

class BDistAppsCmd(bdist_apps):
    def run(self):
        bdist_apps.run(self)
        bld = FlatpakBuilder(
            self,
            'org.panda3d.Asteroids',
            '/home/you/panda3d/samples/asteroids/dist/flatpak_repo',
            'D43B...B5',
            '/home/you/path/to/gpg',
	    'file:///home/you/panda3d/samples/asteroids/dist/flatpak_repo')
        bld.build()

setup(
    ...
    cmdclass={"bdist_apps": BDistAppsCmd},
    ... )

Then, launch the standard Panda3D build command:

python setup.py bdist_apps

At the end of the process, you will get the builds created by Panda3D, your
Flatpak repository in dist/flatpak_repo/ and a .flatpakref file in dist/.

Let's install Asteroids:
flatpak --user install file:///home/you/panda3d/samples/asteroids/dist/asteroids-stable.flatpakref

Let's run Asteroids:
flatpak run org.panda3d.Asteroids

Now, you can delete build/ and dist/, then you can rebuild it changing the URL
(from file:///... to https://...), so you can use it online (in place of
locally): just upload the repo to the path you specified and the .flatpakref
somewhere and everything should work.
