Meta

====

.. image:: https://secure.travis-ci.org/srossross/Meta.png?branch=develop

A Pure Python module containing a framework to manipulate and analyze 

python ast's and bytecode.

Example

========

This shows how to take python source to a code object and back again from within python::

    import meta, ast

    source = '''

    a = 1

    b = 2

    c = (a ** b)

    '''

    

    mod = ast.parse(source, '', 'exec')

    code = compile(mod, '', 'exec')

    

    mod2 = meta.decompile(code)

    source2 = meta.dump_python_source(mod2)

    

    assert source == source2 

This shows the depyc script. The script compiles itself, and then the compiled script extracts itself::

    

    DEPYC_FILE=`python -c"import meta.scripts.depyc; print meta.scripts.depyc.__file__"`

    depyc $DEPYC_FILE --pyc > depycX.pyc

    python -m depycX depycX.pyc --python > depycX.py

    echo depycX.py

Notes

======

 * Meta is python3 compliant (mostly)

 

Bugs

=====

 * The decompliler does not yet support complex list/set/dict - comprehensions 

Testing 

======= 

`python -m unittest discover meta`
