Package description here.

nr.pylang.ast

This package provides tools for processing the AST as generated by the Python ast module.

Module: dynamic_eval

This module provides an AST rewriter that takes and Read/Write operations on global variables and rewrites them to retrieve the variable by a function instead. Non-global variables are left untouched.

Example:

import os
from os import path

parent_dir = path.dirname(__file__)

def main():
  filename = path.join(parent_dir, 'foo.py')
  print(filename)

Will be converted to:

import os; __dict__['os'] = os
from os import path; __dict__['path'] = path

__dict__['parent_dir'] = __dict__['path'].dirname(__dict__['__file__'])

def main():
  filename = __dict__['path'].join(__dict__['parent_dir'], 'foo.py')
  __dict__['print'](filename)
