Sprint 2013/12/07

When

Saturday, 7th of December, 2013, starting from around 10:00

Where

Praekelt have offered to host us.

Background

There is a lot of interest in getting pygame running efficiently on PyPy Notably, the Raspberry PI foundation are rather keen on the idea.

What?

  • Try to get a subset of pygame working on cffi
    • At least pygame.time, pygame.display, pygame.event, pygame.Rect and pygame.draw
    • Ideally also pygame.font, pygame.rotate, pygame.transform
  • Target a simple tutorial - possibly http://inventwithpython.com/wormy.py
  • Test performance on Raspberry PI

Other stuff

  • Use existing sdl cffi project?
    • pysdl-cffi (targets SDL 2.0, and doesn't wrap other needed libraries)
    • Others?
  • Roll our own cffi wrappers?
    • Duplicates a bunch of existing work

Repository and results

  • Repository on github - https://github.com/CTPUG/pygame_cffi
  • At the end of the sprint, we had enough working that a couple of games were moderately playable.
  • Some [post sprint hackery got most of the event loop working, and it reached the point that some of the CTPUG pyweek entries could be played (although not without graphical glitches)
  • This was tested with both cpython and pypy.
  • The Raspberry PI foundation will fund someone to work on extending this to see how far it goes.
