macPython: accessing string data in resource files

Well, the module you want is the Res module.  There's no documentation 
for this module that I'm aware of, but the docstrings are pretty good.

To get at a STR# resource, try something like this:

Python 2.1 (#92, Apr 24 2001, 23:59:23)  [CW PPC GUSI2 THREADS] on mac
Type "copyright", "credits" or "license" for more information.
>>> import Res
>>> resfile = "strings.rsrc"  # or the full path to your res file
>>> rf = Res.FSpOpenResFile(resfile, 0)
>>> strh = Res.GetResource("STR#", 128)
'\x00\x04\x18this is the first string\tstring #2\x12and a third 
string\x1afinally, the fourth string'

Now, at this point you've got the STR# data, but it is encoded as a 
series of Pascal strings.  The resource data starts with a null byte, 
the next byte is the number of strings, and then each string begins with 
a byte telling how long the following string is.  You could probably 
write a function which converts this into a list, but as far as I'm 
aware of there is no library function which will do it for you.

Hope that helps,
