ReprTraceback 1.0.2

Improve stack traces with the values associated with each argument in each frame.

ReprTraceback

ReprTraceback is a module that utilizes the sys.excepthook to throw custom traceback messages. Specifically, it includes values of positional, var, and keyword arguments.

Before & After

Before

Traceback (most recent call last):
  File "main.py", line 17, in <module>
    main()
  File "main.py", line 13, in main
    get_element(n, verbose, *args, **kwargs)
  File "main.py", line 5, in get_element
    return my_list[k]
           ~~~~~~~^^^
IndexError: list index out of range
# What is k? What was passed in? We'll never know. Hopefully it's easy to reproduce.

After

Traceback (most recent call last):
  File "main.py", line 17, in <module>
    main()
  File "main.py", line 13, in main
    main()
         ^^
  File "main.py", line 5, in get_element
    get_element(k=5, verbose=True, args=('my', 'var', 'args'), kwargs={'Repr': 'Traceback'})
                ^^^^^^^^^^
IndexError: list index out of range
