xdbg is an IPython extension that brings debugger features to the live coding environment. Works well with the IPython console, notebooks, and IPython-enabled text editors.

- Move the REPL's scope into any imported module
- Hotfix functions being debugged by specifying the correct behavior, instead of just watching them fail
- Works well with text editor integration such as the hydrogen package for the Atom text editor

You can activate xdbg inside an IPython kernel by running %load_ext xdbg. To load it automatically,
list it in your IPython configuration file, e.g.
c.InteractiveShellApp.extensions = ['xdbg']The configuration file is usually located at ~/.ipython/profile_default/ipython_config.py, and can be
generated by running ipython profile create.
