Utilities for abstract syntax trees and parsing with PLY.
Project description
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
LexerandParserclass, 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.
