    script to translate from compiler AST

    Hi!

    I'm looking for a script to translate from 'compiler' AST to py source
    and executable code.

    Google search reveals hardly useful links.

    Is there something like that or it is left as an exercise for a curious
    developer?

      Have you looked at the parser module?
      (http://www.python.org/doc/current/li...le-parser.html) it does
      have some functions operating on AST. The is also a visitor patter
      support in the compiler module.

      HTH.

          Um, not sure what you're asking for here. You might be asking for
          Python2C, but it's probably not what you want...

              Well, I'm speaking exactly about the compiler module. Imagine, I've built
              an AST that I want to run. I've not found an easy (read library) way to do
              that, hence the questions.

                  (read library) way to do that, hence the question.

                  Is there a way or I'd better write a proper 'visitor' myself?

                          Wow, thanks! Exactly what I need. Unfortunately pycodegen is not yet
                          documented :)
