pharoahPython QML Reader
For those of you who haven't been reading this forum much lately, I've been working on a little QML reader in Python. The result is pretty limited because it uses only standard libraries in an effort to be cross compatible, so it does not display colors and probably won't display special characters either. Still, it's good enough that Brandon can participate in the chat from his Mac now (although there is no refresh, not my fault but Python's). To run this code, save it as pqml.py and then open up your terminal, find the correct directory, and type: python pqml.py It should run without any need to install python on most Linux and Mac machines.
