Yes, I'm a bit attracted to python as well. Possibly because I already
know the syntax, although I haven't used it for some years.

I've attached a patch against gnubg.c 1.430 that embeds python in gnubg.
There is also a new file gnubgmodule.c.

You need to add the following flags to the Makefile:

COMMON_INCS:

-I/path/to/python.h    (e.g.,-I/usr/include/python1.5)

COMMON_LIBS:
/path/to/libpython.a   (e.g, /usr/lib/python1.5/config/libpython1.5.a)
-Wl,--export-dynamic   (for gcc, I don't know about other compilers)


The escape to python is >.

Here's an example:

address@hidden gnubg-head2 850]$ gnubg -t
(No game) >print 1+1
2

or another example:

(No game) >
>>> import sys
>>> print sys.platform
linux-i386
>>> [Ctrl+D]


or a third example:

(No game) >
>>> import gnubg
>>> print gnubg.setcubeinfo()
{'jacoby': 1, 'crawford': 0, 'move': 0, 'beavers': 1, 'cube': 1,
'matchto': 0, 'bgv': 0, 'cubeowner': -1, 'score': (0, 0), 'gammonprice':
((0.0, 0.0), (0.0, 0.0))}
>>> print gnubg.setcubeinfo(4,1,1,9,(0,4),0)
{'jacoby': 0, 'crawford': 0, 'move': 1, 'beavers': 0, 'cube': 4,
'matchto': 9, 'bgv': 0, 'cubeowner': 1, 'score': (0, 4), 'gammonprice':
((1.55229616165, 0.679036140442), (0.231332331896, 1.20560128547e-09))}
>>> [Ctrl+D]

Very fun and simple!

Of course, I just need to add interfaces to the remaining 200 internal
gnubg functions.

Joseph, is this something that could be useful for you?
