A hack on top of 2to3 for modernizing code for hybrid codebases.

Project description

Python           _              _
   _ __  ___  __| |___ _ _ _ _ (_)______
  | '  \/ _ \/ _` / -_) '_| ' \| |_ / -_)
  |_|_|_\___/\__,_\___|_| |_||_|_/__\___|

This library is a very thin wrapper around lib2to3 to utilize it
to make Python 2 code more modern with the intention of eventually
porting it over to Python 3.

It does not guarantee, but it attempts to spit out a Python 2/3
compatible codebase.  The code that it generates has a runtime
dependency on `six`.

Unicode Literal Control:

  - By default modernize will wrap literals with the six helpers.
    This is useful if you want to support Python 3.1 and Python 3.2
    without bigger changes.
  - Alternatively there is the ``--compat-unicode`` flag which
    does not change unicode literals at all which means that you
    can take advantage of PEP 414.
  - The last alternative is the ``--future-unicode`` flag which
    imports the ``unicode_literals`` from the ``__future__`` module.
    This requires Python 2.6 and later and will require that you
    mark bytestrings with ``b''`` and native strings in ``str(b'')``
    or something similar that survives the transformation.
