Hi Diego,
Yes, even Distutils takes this approach. We can take a look at the
function get_platform_lib(), where they use os.name to figure out what
platform the program is running under.
http://svn.python.org/projects/python/trunk/Lib/distutils/sysconfig.py
(Hey, I didn't realize that python.org moved their source code repository
from CVS to Subversion! When did this happen?! Oh, ok, I see the PEP
now. http://www.python.org/peps/pep-0347.html. Cool!)
Sorry, got off track. Anyway, Distutils appears to do a fairly simple
case analysis:
######
if os.name == "posix":
## text cut
elif os.name == "nt":
## text cut
elif os.name == "mac":
## text cut
elif os.name == "os2":
## text cut
######
So if it's good enough for Distutils, it may work out for you. *grin*
You may want to isolate whatever platform-dependent parts of your
application you have off to a separate module. That is, if you can, try
writing modules that hide away the platform ugliness, so that the rest of
your application can behave as if everything were platform-independent.
Best of wishes to you!
