"Debugging is twice as hard as writing the code in the firstplace.
Hi,
My idea is to create a system working as follows: each module knows
path to plugin directory, and that directory contains modules which
may add hooks to some points in the code.
Inspired by http://www.python.org/pycon/2005/papers/7/pyconHooking.html
I would create a class like this:
class P
more. But the
problem is you'd waste even more memory - 2/3 actually. So, doubling the size
of chunks is used, and the technique is quite common.

Using a SAX / full-compliant DOM parser could be good for learning things,

Well, of course. As I said, it was untested :) I just copied the path string,

Yup. Too bad I've had the opportunity to work that way (pair programming) only
few times, and even then it wasn't XP-style in any other way. It is
1.0. Good component
design is crucial because you eventually want to do major rewrites later.

If you need to stick with comma as a separator and the format is relatively
fixed, I'd probably use some parser module instead. Regular expressions are
nice too, but it is easy to

skeleton first, then the tests and then the logic for the skeleton
- you would be creating tests before the code, but many people wouldn't regard
