How to set condition breakpoints?

[Christopher J. Bottaro]

I have a script with a class in it:
class Class:
def f(x, y):
# do something

I start up the debugger like this:
python /usr/lib/python2.3/pdb.py myscript.py

I want to set a conditional breakpoint:
b Class.f, x == 1 and y == 2

....but that doesn't work. How can I do what I want?

Thank you.

You might consider boa-constructor, implemented for Windows and Linux.

I believe that it provides this functionality. Of course it provides a
lot more.

Hmm, thanks for the suggestions. One more quick question. Is it even
possible to set a breakpoint in a class method in pdb.py? I can't even say
"break Class.f" without the condition. I don't think the documentation for
pdb is very good...=(

Thanks.

What happens? I can do it...

However, I had to fix "pdb" to prevent it to set the breakpoint
inside the docstring (where it is not effective).

I hope the fix found its way into the most recent Python versions
(2.3.4 and 2.4).
