I wrote something like this (called pyunparse) a little while ago. It's not the cleanest code in the world, but it worked for my original use case (debugging Logix, which uses python ASTs as an IR): http://www.pycs.net/users/0000445/stories/7.html Cheers, /arg On May 24, 2005, at 9:56 AM, Jeremy Hylton wrote:

Would there be any interest in extending the compiler package with tools for AST transformations and for emitting Python source code from ASTs?
Sure. Eventually, we'll have to figure out how to unify the compiler package AST and the ast-branch AST, but don't let that delay you now.
I was experimenting with possible translations for exception chaining and wanted to run some automated tests, so i started playing around with the compiler package to do source-to-source transformations. Then i started working on a way to do template-based substitution of ASTs and a way to spit source code back out, and i'm wondering if that might be good for experimenting with future Python features.
(If there's already stuff out there for doing this, let me know -- i don't intend to duplicate existing work.)
I don't know of any existing work, but it certainly sounds useful.
