Overview
Python's traceback module does pretty formatting and printing of tracebacks, but does not add the local variable of each frame. This module adds this capacbility to the traceback module by monkeypatching.
Usage
Here's an example on how to use this module:
from infi.traceback import traceback_context, traceback_decorator
def call():
text = 'some text'
boolean = True
obj = object()
raise RuntimeError()
@traceback_decorator
def test_decorator():
import traceback
try:
call()
except:
traceback.print_exc()
def test_context():
with traceback_context():
import traceback
try:
call()
except:
traceback.print_exc()
test_decorator()
test_context()This prints:
Traceback (most recent call last):
File "examples/readme_example.py", line 14, in test_decorator
call()
File "examples/readme_example.py", line 9, in call
raise RuntimeError()
Local variables:
'text': 'some text'
'boolean': True
'obj': <object object at 0x100283200>
RuntimeError
Traceback (most recent call last):
File "examples/readme_example.py", line 21, in test_context
call()
File "examples/readme_example.py", line 9, in call
raise RuntimeError()
Local variables:
'text': 'some text'
'boolean': True
'obj': <object object at 0x100283210>
RuntimeErrorA common is use-case is to have a pretty traceback when an un-caught exeption is raised by a console script entry point. For that, you can use:
from infi.traceback import pretty_traceback_and_exit_decorator
@pretty_traceback_and_exit_decorator
def entrypoint():

Run the following:
