ipdbugger

ipdbugger is a code debugging tool based on ipdb.

Use the debug decorator on functions or classes to debug them. What actually happens: it surrounds each statement of the functions with a try-except, and starts an ipdb session in the exception handling section.

Installing

$ pip install ipdbugger

Using

from ipdbugger import debug

@debug
def f():
    foo = 1 + 1
    bar = 1 / 0
    baz = 2 + 2

Now when you run f(), you'll get into an ipdb shell right after the error (the division by zero):

>>> from ipdbugger import debug
>>> @debug
    def f():
        foo = 1 + 1
        bar = 1 / 0
        baz = 2 + 2

>>> f()
Traceback (most recent call last):
   File "<ipython-input-2-5720bb02ab1d>", line 4, in f
    bar = 1 / 0
 ZeroDivisionError: integer division or modulo by zero
> <ipython-input-2-5720bb02ab1d>(5)f()
      2 def f():
      3     foo = 1 + 1
      4     bar = 1 / 0
----> 5     baz = 2 + 2
      6

ipdb> foo
2
ipdb>

From there, you have a couple of choices:

• retry the action
• continue with the rest of the flow (and ignore the error)
• raise the exception, as if you didn't catch it at all
• Use any other of the available ipdb commands, like jump
