A debugging tool that can help you what happened when you code quits unexpectedly
Project description
wthell
wthell is a debugging tool for python to interactively check frame stack when your code did something unexpectedly
Install
You can install wthell
from pip
pip install wthell
Usage
It's super easy to use wthell. Just import it and it's done!
import wthell
If there's an uncaught exception, you will enter an interactive shell like this:
def g(a, b):
a += h(a)
b += 3
> raise Exception("lol")
Exception raised: <class 'Exception'> lol
back(b) -- go to outer frame | in(i) -- go to inner frame
clear(cl) -- clear the console | reset(r) -- back to trigger frame
continue(c) -- resume the program | ctrl+D -- quit
>>>
You will be in the frame(function) that raised exceptions in the beginning.
- Type
back
to go to outer frame(its caller). - Type
in
to go to inner frame(when you already go out). - Type
clear
to clear the console prints - Type
reset
to go back to the original frame that triggered wthell - Type
continue
to resume the program
wthell will record the full call stack so you can check any frame.
While you are in a stack, you can type anything that you want to evaluation to help you debug.
>>> a
13
>>> a + 1
14
>>> h(a)
16
>>>
Or you can trigger wthell anywhere in your code
def suspicious_function():
# I want to check here!
wthell.wth()
wthell behaves like an interactive shell.
Happy debugging!
