Re: [Bashdb-pydb] (no subject)

Thanks for the info. When you write "Syncronization is perfect" did
you try the situation where you have some Python scripts running from
e: and some running from c:?

Here's a little test for example:
In file e:/Sources/CapFilterScanner/t1.py

import os, sys
sys.path.insert(0, "c:") # or c:\\ or c:/ - you'll have to see what works here
import t2


In file c:/t2.py:

print "t2 here"


First, when you run t1.py you should see "t2 here". You may have to
change that sys.path.insert to get this right.

After that works, then inside pydb try stepping through this program
to make sure you switch from t1 to t2.

Thanks.

I've committed the regular expression change, but not the one listed
you quoted, because I have feeling the above might not work. Instead
the regular expression commited was the *second* one I listed:

 "^(\\(\\(?:[a-zA-Z]:\\)?[-a-zA-Z0-9_/\\\\.]*\\):\\([0-9]+\\)):[ \t]?"

The ?: is need to make sure the numbering of patterns matched is
correct. It works on Unixy path names if it doesn't on DOSy path names
I'll go to the version you quote below.
