ast2json 0.1

Introduction

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).

Installation

pip install ast2json
# or to have lastest version
pip install git+git://github.com/Psycojoker/ast2json.git

Usage

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

>>> ast = ast2json(parse(open('some_python_source_file.py').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('some_python_source_file.py').read())

Example

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

{
    "body": [
        {
            "_type": "Print",
            "nl": true,
            "col_offset": 0,
            "dest": null,
            "values": [
                {
                    "s": "Hello World!",
                    "_type": "Str",
                    "lineno": 1,
                    "col_offset": 6
                }
            ],
            "lineno": 1
        }
    ],
    "_type": "Module"
}
