# PyOpenGL (specifically, OpenGL.__init__) reads a "version" text file
# containing the version number to export it as OpenGL.__version__. When
# packaging with PyInstaller, the 'version' file does not exist, and importing
# PyOpenGL results in an IOError.
# The (convoluted) solution is to override Python's builtin "open" with our
# own function which detects when "version" is opened and returns some fake
# content stream (through cStringIO).
__realopen__ = open
def myopen(fn, *args):
if isinstance(fn, basestring):
if fn.endswith("version") and ".pyz" in fn:
# Restore original open, since we're almost done
__builtins__.__dict__["open"] = __realopen__
# Report a fake revision number. Anything would do since it's not
# used by the library, but it needs to be made of four numbers
# separated by dots.
