The AstToolBox allows a developer to start from a python source file and see how a series of ast.NodeTransformers change it, and how a CodeGenerator will render the AST at any given point.
Files and transforms can be reloaded at any time which facilitates development. If a tree does not look right after some transformation, the transform can be edited and reloaded and reapplied.
This tool was derived from AstViewer
Command line example:
%> ast_tool_box myprog.py
Examples to use from within Python:
`python >>> from astviewer import view >>> view(file_name='myprog.py', width=800, height=600) >>> view(source_code = 'a + 3', mode='eval')`
