Embed git in package
package.ps1 fetches PortableGit and embeds it in the package. This
eliminates all but one runtime dependency (MSVC++ Redistributable).
* Move Python into a new FOSS folder.

These are based on +``lib2to3`` and use fixers from ``2to3``, ``3to2``, and ``python-modernize``. + +``futurize`` passes Python 2 code through all the appropriate fixers to turn it +into valid Python 3 code, and then adds ``__future__`` and ``future`` package +imports. + +For conversions from Python 3 code to Py2/3, use the ``pasteurize`` script +instead. This converts Py3-only constructs (e.g. new metaclass syntax) and adds +``__future__`` and ``future`` imports to the top of each module. + +In both cases, the result should be relatively clean Py3-style code that runs +mostly unchanged on both Python 2 and Python 3. + + +.. include:: futurize.rst + +.. include:: futurize_cheatsheet.rst + +.. include:: pasteurize.rst + +.. include:: conversion_limitations.rst |
