formatter2 is a Python formatter based on the tokenize library in Python. Due to a bug with line continuations we are currently running a fork of the tokenize library however.
During every format sequence the compile method is used to check if no code has been broken, but backing up is still a good idea.
The library is made to be very extendable and configurable but it's still in the beginning phase. Eventually this will become a fully featured formatting tool for Python.
To install simply execute python setup.py install or pip install formatter2. If you want to run the tests first, run nosetests
To format all of your code recursively (MAKE BACKUPS!):
python-formatter -r DIRECTORY
Or:
format-python -r DIRECTORY
