Utilities for abstract syntax trees and parsing with PLY.
[![Build Status][build_img]][travis] [![Coverage Status][coverage]][coveralls]
Bare essentials for building abstract syntax trees (AST) and Python lex-yacc ([PLY](https://github.com/dabeaz/ply)) parsers. The package includes:
- two classes for tree nodes: Terminal, Operator
- a Lexer and Parser class, and a helper function to erase and rewrite the table files.
The examples under examples/ demonstrate how to use these classes to create a richer AST, a parser, and different backends that use the same parser.
These classes provide the boilerplate for parsing with PLY, and are based on code that was developed in [tulip](https://github.com/tulip-control/tulip-control) and [promela](https://github.com/johnyf/promela).
