Documentation

Current docs for latest build of pyparsing can be found online here.

Older docs in previous EpyDoc format can be found here. These are only current as of pyparsing 2.2.0, as readthedocs has become the de facto standard for uploading docs via pypi.

I have added a unit testing module simple_unit_tests.py to the source directory, after realizing that unit tests can provide instructional and documentation value as well as code validation. Please view those classes for simple sample parse expressions, and corresponding input text and parsed data or exceptions. (PRs for this file are strongly encouraged!)
