It uses the same LALR(1) parsing algorithm +as yacc and has most of its core features. It is compatible with all +modern versions of Python. + +PLY was originally created in 2001 to support an Introduction to +Compilers course at the University of Chicago. As such, it has almost +no features other than the core LALR(1) parsing algorithm. This is by +design--students should be made to suffer. Well, at least a little +bit. However, from a more practical point of view, there is a lot +flexibility in terms of how you decide to use it. You can use PLY to +build Abstract Syntax Trees (ASTs), simple one-pass compilers, +protocol decoders, or even a more advanced parsing framework. |
