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.
