Hi all,
What is your favorite tool to help you debug your
code? I've been getting along with 'print' statements
but that is getting old and somewhat cumbersome.
I'm primarily interested in utilities for Linux (but
if you have recommendations for Windows, I'll take
them too :)
I use emacs as my primary development environment, FWIW.
Someone mentioned winpdb .. anyone have experience/comments
on this? Others?
I am frequently in the IPython interactive prompt for testing out stuff and even
as the main way of running my code. It has a nice feature that when you get a
traceback, you can open up pdb post-mortem.
In [8]: def f(x):
...: y = 1 / x
...: return y
...:
In [9]: f(1)
Out[9]: 1
In [10]: f(0)

ZeroDivisionError Traceback (most recent call last)

ZeroDivisionError: integer division or modulo by zero

I have a little function that I've been using recently to print out the function
I am currently in along with the arguments:
def whereami():
""" Print the current function call.
import kerntrace;kerntrace.whereami()
"""
import inspect
frame = inspect.currentframe(1)
args, varargs, varkw, f_locals = inspect.getargvalues(frame)
if args[:1] == ['self']:
del args[0]
print '%s%s' % (frame.f_code.co_name, inspect.formatargvalues(args, varargs,
varkw, f_locals))
I think pdb is okay, but I am looking forward to pydbgr's completion.
