Bug Reproducer Assistant

Bug-reproducer Assistant is a tool that extracts behavior from live running code (Python or C++), generating a program equivalent to the original, but only with the functions or classes selected by the programmer. It's been developed in Python, with the help of metaprogramming techniques to decorate the selected functions.

This tool will be presented in Pycon 2011

Known issues

Parser needs improvement. For C++ projects, it requires a very simple syntax. It doesn't solve comments, or function declarations split in several lines.
