pyparsing v2.2.0 Release Notes

Release Date: 2017-03-01 // almost 5 years ago
    • ⬆️ Bumped minor version number to reflect compatibility issues with OneOrMore and ZeroOrMore bugfixes in 2.1.10. (2.1.10 fixed a bug that was introduced in 2.1.4, but the fix could break code written against 2.1.4 - 2.1.9.)

    • ⚡️ Updated setup.py to address recursive import problems now that pyparsing is part of 'packaging' (used by setuptools). Patch submitted by Joshua Root, much thanks!

    • 🛠 Fixed KeyError issue reported by Yann Bizeul when using packrat parsing in the Graphite time series database, thanks Yann!

    • 🛠 Fixed incorrect usages of '\' in literals, as described in https://docs.python.org/3/whatsnew/3.6.html#deprecated-python-behavior Patch submitted by Ville Skyttä - thanks!

    • Minor internal change when using '-' operator, to be compatible with ParserElement.streamline() method.

    • 📜 Expanded infixNotation to accept a list or tuple of parse actions to attach to an operation.

    • 🆕 New unit test added for dill support for storing pyparsing parsers. Ordinary Python pickle can be used to pickle pyparsing parsers as long as they do not use any parse actions. The 'dill' module is an extension to pickle which does support pickling of attached parse actions.
