PyParadox is a nix launcher for Paradox titles.

Project description


PyParadox is a nix launcher for Paradox titles.


  • Operating system:
    • Linux: Any modern distribution with up-to-date packages
    • OS X: Latest version
    • Windows: 7 and later
  • Python: 3.3+
  • Qt: Qt 5.3+ via PyQt5


  • Games: PyParadox supports all cross-platform grand strategy titles of Paradox Interactive that use the Clausewitz engine. To date, these include:
    • Crusader Kings II
    • Europa Universalis IV
  • Steam: PyParadox can be launched from Steam when starting the title from the Steam interface. All Steam integration should work just fine. A small configuration inside Steam is required to make sure that PyParadox is used instead of the stock launcher. See the documentatation on how to set this up.
  • PyParadox separates the expansion DLCs from the regular DLCs. This should make it easier to start up your game with the exact expansions you want.
  • PyParadox fixes an anomaly under Linux that causes the game to mess with the screen resolution when alt+tabbing. This anomaly was introduced when Paradox released their (new) stock launcher for Linux. By bypassing this launcher, PyParadox also bypasses the anomaly.


Read the documentation.


0.3.5 (2015-08-17)

  • Added basic logging.

0.3.4 (2015-08-09)

  • Moved Linux default game directory from ~/.local/share/Steam/... to ~/.steam/root/.... The former directory was deprecated by Ubuntu, but not by Arch. The latter directory works on both distributions.
  • Fixed OS X compatibility. Now launches the game correctly.

0.3.3 (2015-07-23)

  • Fixed bug that caused pyparadox-qml to fail to launch. This presumably only happens in more recent versions of Qt/PyQt5.

0.3.2 (2015-07-18)

  • Added new expansions to the list of expansions.

0.3.1 (2015-04-23)

  • Scrollbars in the QML front-end are now always visible.
  • QML front-end now uses the absolute minimum imports that I could find. This has resulted in the use of Qt 5.3 rather than Qt 5.2. It is still possible to use Qt 5.1 with the QtWidgets version.

0.3.0 (2015-04-23)

  • Implemented QML front-end that is almost identical to the QtWidgets front-end. This is a proof of concept to indicate that the backend is fairly decoupled. There is some code repetition, but almost no reptition in business logic. Then again, the business logic of this program is fairly small.

0.2.3 (2015-04-17)

  • Added error message when program fails to launch.
  • Greatly improved documentation.
  • Fixed bug that caused a failed launch on Ubuntu 14.04. Incidentally, this also causes the menu bar to be used locally rather than integrated into the top panel bar. Fortunately, PyParadox doesn’t have a menu bar. Yet.

0.2.2 (2015-04-12)

  • Patched a bug that caused PyParadox to fail to launch from Steam.
  • Removed Python 2.7 support from PyPI.

0.2.1 (2015-04-11)

  • Minor patches to documentation because apparently I can’t release anything without messing that stuff up.

0.2.0 (2015-04-11)

  • Complete rewrite of the project, with reuse of some code.
  • Now no longer supports Python 2.7 and Qt 4. This program will only work with Python 3.3+ and PyQt5.
  • Configuration files relocated to a different location. Old configuration files no longer valid.
  • Graphical user interface makes use of Qt .ui files, rather than hardcoded QtGui/QtWidgets code.
  • A lot of functionality has been decoupled from the user interface. While the UI code performs some glue logic, it should be relatively trivial to cook up a user interface in a different framework. An experimental QML front-end is under consideration.
  • Unit tests are a lot leaner, using fewer mocks and patches, instead relying much more on dependency injection.
  • Documentation rewritten.

0.1.3 (2015-01-31)

  • Added –pyqt4 argument to force the usage of PyQt4.
  • Fixed PyQt4 compatibility issues.

0.1.2 (2014-07-20)

  • Fixed typo that caused README to display incorrectly.

0.1.1 (2014-07-20)

  • Sweetened up the README with images of the program.

0.1.0 (2014-07-20)

  • Added descriptive error message when game fails to run.
  • Added experimental PyQt4 support.
  • Detailed installation instructions per platform added.
  • A logo of each game is now displayed.
  • Mods and DLCs are now sorted.
  • The application now has an icon.

0.0.2 (2014-07-13)

  • Windows compatibility added.
  • Window titles set correctly.
  • Small UI tweaks (alt-shortcuts).
  • Better game process management.
  • Better unit testing, though incomplete.
  • Just general code refactoring.
  • Tested on Kubuntu 14.04 and Windows 8.1. Still not sure about OS X.

0.0.1 (2014-07-10)

  • First release on PyPI.
  • Basic functionality. No polish yet.
  • Only tested on Kubuntu 14.04.
