convert a python source code into json-dumpable data (dict and lists with strings, ints, ...)

Project description


ast2json is a small module that will convert any python AST node into its ast representation formated in a JSON compatible python representation (list and dicts containing string, ints and null).


pip install ast2json
# or to have lastest version
pip install git+git://


>>> import json
>>> from ast import parse
>>> from ast2json import ast2json

>>> ast = ast2json(parse(open('').read()))
>>> print json.dumps(ast, indent=4)

If you are lazy, “str2json” will apply the “parse” method of ast on a string for you, so you’ll be able to write:

>>> str2json(open('').read())


This is the result of converting ‘print “Hello World!”’ (and applying json.dumps on the result).
