TatSu 4.1.0

[Juancarlo Añez]

TatSu v4.1.0 was released

* https://pypi.org/project/tatsu/

* http://tatsu.readthedocs.io/en/latest/

* https://github.com/neogeny/TatSu

TatSu (the successor to Grako) is a tool that takes grammars in a variation
of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python.

CHANGES

*  New support for *left recursion* with correct associativity. All test
cases pass.

*  Left recursion is enabled by default. Use the``@@left_recursion ::
False`` directive to diasable it.

*  Renamed the decorator for generated rule methods to ``@tatsumasu``.

*  Refactored the ``tatsu.contexts.ParseContext`` for clarity.

*  The ``@@ignorecase`` directive and the ``ignorecase=`` parameter no
longer appy to regular expressions (patterns) in grammars. Use  ``(?i)`` in
the pattern to ignore the case in a particular pattern.

*  Now ``tatsu.g2e`` is a library and executable module for translating
`ANTLR`_ grammars to **TatSu**.

*  Modernized the ``calc`` example and made it part of the documentation as
*Mini Tutorial*.

*  Simplified the generated object models using the semantics of class
attributes in Python.
