Ast tree and python code

[Yermat]

Hi,

Does someone know how I can reverse an AST tree back into python code
with few modification ?
What I want to do is to complete trees before writing them back but in a
way not to far from the original code ? Especially, indentation, line
return, etc.

Of course, I could program it myself but if someone already done it...

If you insist on doing this in Python, I don't have any help.

Otherwise, if you want to carry out arbitrary transforms on Python code,
you might be interested in the DMS Software Reengineering Toolkit.
It parses many languages (including Python) into a language
specific AST, can carry out source-to-source transformations
on those trees, and can then prettyprint source text from
those tree. It retains comments, indentation, the
format of numbers, you name it.
