Python AST manipulator
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.
