"errno" module needed - is platform-dependent

[GoogleCodeExporter]

CPython has an "errno" module, which is just a table of the constants from 
"errno.h".  It's a built-in; there is no "errno.py".  The problem is that the 
error numbers are platform-dependent.  So it has to be built for each platform, 
hopefully as part of Shed Skin's library. 

(I'm trying to get more of the standard modules to work, starting at the 
bottom.  My current goal is to work up to urllib2 and process web pages.)

Wrote a program to generate "errno.py. Attached.

thanks! I think it is probably a better approach to include handwritten 
lib/errno.?pp files though, similar to how the 'signal' module is supported at 
the moment. that way it should also work on each platform, without having to 
first build the library. 

is this something you'd be interested in looking into further?

That's up to you.  I'd be inclined to generate "errno.py" automatically during 
installation.  You should never have to tell the computer something it already 
knows.

I don't really understand your point. the computer "knows" everything in 
errno.h, and using this, it's simply a matter of autogenerating lib/errno.* 
once.. autogenerating on installation could also be viewed as telling the 
computer something it already knows :P 

this issue was marked as an 'easy task' in the wiki section. I'm thinking about 
permanently leaving a fixed amount of easy issues open, to encourage newcomers 
to look into fixing issues.. please let me know if you'd like me to fix an 
issue quickly though. I'd be happy to make an exception on request.
