Utilities for abstract syntax trees and parsing with PLY.

Project description

Build Status

About

Bare essentials for building abstract syntax trees (AST) and Python lex-yacc (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 and promela.
