Where is print_pygame?

[Oyster]

Hi, all
I am using sympy 0.6.2 on py24, and I have pygame module. But I met
this error. Does that mean pygame is not supported by sympy anymore?
If so, shall we remove examples\print_pygame.py out?

Thanx

We decided to remove support for pygame because the same functionality
can be achieved with pyglet, which we ship with sympy anyway (see
preview module). Unfortunately preview module works only on platforms
with provide pexpect module (see issues #872, #970).

It would be better to fix those examples and rename the file to
examples/preview.py

Looking forward to seeing patches fixing this,
Mateusz

so bad, I use windows which does not support pexpect :(

I see. We could achieve the same thing using "os.system", which should
work on windows too. Do you have tex installed? How do you invoke it?
E.g. would

os.system("tex somefile.tex")

work? If so, it'd be easy to fix it. If not, we'd need help from
someone using windows (you? :) to get this resolved.

But I do not use tex.

matplotlib supports some nice mathematical expressions without
tex(http://matplotlib.sourceforge.net/tutorial.html, search 'Writing
mathematical expressions'). I donno whether it is useful for sympy

I can help sympy if you need someone who uses windows
