Byte-code and ast programming tools
Project description
Meta
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, '<nofile>', 'exec') code = compile(mod, '<nofile>', '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
