This README file is for the kjParsing package which
is experimental software made freely available to whoever
wants to fiddle with it.
WHAT
====
The kjParsing package is a parser generator written in Python
which produces parsers written in Python.
kjParsing package consists of the following
files:
kjParser.py
-- the basic data structures and functions needed for performing
LR parsing in Python.
kjParseBuild.py
-- functions and data structures for SLR grammar
compilation in Python. (It wouldn't be too
difficult to extend these to LR1, but I don't
have any motivation to do so, let me know if you'd
like LR1, and why. Maybe I'll implement it or
give hints on how you can do so.)
kjSet.py
-- Miscellaneous set and graph operations used by
the other two modules.
What the ``kj'' prefix stands for is for me to know
and you to find out. I hope the prefix prevents name
collisions.
Also included are some documentation files and a few example
usage files together with the COPYRIGHT file which explains
that I own the copyright, but you may use the package for any
purpose provided you respect and propagate the copyright, and
understand that I accept no liability whatsoever for any
difficulties you may have.
WHY
===
I'm a programming language experimenter. I've done a lot of language
experiments in Common Lisp, but since there is no good free
implementation of Common Lisp that runs in a lot of different
environments with standard os interfaces, I was unable to share
my toys to any reasonably large audience. Hence I started looking
around for a better platform for my fiddling, and Python looks like
the best choice in existence.
But to do any real fiddling, I needed a parser generator; so
I wrote one in Python.
Please let me know if you try using this package, and pass on any comments
or suggestions. Thanks.
