Module cst2source

Module used to unparse a parse tree and recreate source. For files not being transformed the Unparser shall unparse the cst into the exact shape of the parsed source ( however indentation size may vary ). For modified csts or new cst fragments some autoformatting heuristics are applied [1]. Additional heuristics are necessary for combining exact reconstruction with autoformatting.

[1] These heuristics is subject to further refinements.

Usage :

   >>> from cst2source import Unparser
   >>> unparse = Unparser()
   >>> import parser
   >>> tree = parser.suite("def f():
 pass  # unparse this fragment").tolist()
   >>> print unparse(tree)

   def f():
       pass  # unparse this fragment
