Re: Graphical Depiction of Parse Trees

You might consider looking at the Zephyr toolkit, specifically ASDL.


http://www.cs.virginia.edu/~zephyr


It is an Abstract Syntax Description Language, and allows you to
describe your hierarchical structures at a high level, and then output
C, C++, SML code (and several others, I think) to manage those
structures. It also has a tool for viewing a "pickled" form of the
structures.
