Produce function trace for Python code in Xdebug format
Project description
This module prints function trace to stdout from the moment it is called:
import xtrace xtrace.start() ... xtrace.stop()
It is also possible to call xtrace as module from the command line:
python -m xtrace <script.py> [param] ...
or use as a standalone script:
python xtrace.py <script.py> [param] ...
The output format is inspired by Xdebug function traces and will likely to merge with it http://xdebug.org/docs/execution_trace to be compatible with PHP inspection tools. But I didn’t have enough time to polish it, so feel free to send a patch if you know how to bring them closer.
This code is released into public domain. Enjoy!

Debugging
To see various internal events that xtrace produces on top of standard data provided by Python, enable DEBUG option:
import xtrace xtrace.DEBUG = True
This will call beep functiton for every interesting event. Feel free to override it (monkeypatch) with your own to filter messages, forward, etc.
