About

=====

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).
