PyBug extends Python's interactive debugger (pdb), making it simpler to add breakpoints to your code.
Usage examples:
# Like pdb.set_trace(), but shorter :) and works with nosetests.
import bug; bug.trace()
# Set a breakpoint at line 35 of package.module
bug.setbreak(35, "package.module")
# Set a conditional breakpoint at line 42 of /path/to/universe.py
bug.setbreak(42, "/path/to/universe.py", "name == 'hitchhiker'")
There are two notable features here that would ideally make it into the pdb module in the Python Standard Library:
-
Easily set a breakpoint at an arbitrary line in an arbitrary module. This is useful when debugging a third-party library where the code cannot easily be edited to add a set_trace() call.
-
Set a breakpoint in a module named by import path rather than file path.
