python-astor

Python AST manipulator

Description

astor is designed to allow easy manipulation of Python source via the AST.

There are some other similar libraries, but astor focuses on the following areas:

- Round-trip back to Python via Armin Ronacher's codegen.py module:

- Modified AST doesn't need linenumbers, ctx, etc. or otherwise be directly

compileable

- Dump pretty-printing of AST

- Harder to read than round-tripped code, but more accurate to figure out

what is going on.

- Easier to read than dump from built-in AST module

- Non-recursive treewalk

- Sometimes you want a recursive treewalk (and astor supports that, starting

at any node on the tree), but sometimes you don't need to do that. astor

doesn't require you to explicitly visit sub-nodes unless you want to:

- You can add code that executes before a node's children are visited,

and/or

- You can add code that executes after a node's children are visited, and/or

- You can add code that executes and keeps the node's children from being

visited (and optionally visit them yourself via a recursive call)

- Write functions to access the tree based on object names and/or attribute

names

- Enjoy easy access to parent node(s) for tree rewriting

This package provides Python 2 module bindings only.
