Grako 3.20.0 released

[Juancarlo Añez]

Added

   -

   Added grako.compile(grammar, name=None, **kwargs) as a substitute for
   grako.genmodel (which remains for backwards compatibility).
   -

   Added a grako.parse(grammar, input, **kwargs) that will compile a
   grammar and uset to parse the given input. For efficiency, parsed grammars
   are cached.
   -

   Added a grako.to_python_sourcecode(grammar, name=None, filename=None,
   **kwargs) that compiles the grammar to the Python sourcecode that
   implements the parser.
   -

   Rename the existing *join* (.{}) expression to *gather*, and use *join* for
   a new expression (%{}) that keeps the separator in the resulting AST.
   -

   Added left-join (<{}) and right-join (>{}) expressions to the grammar.

Changed

   -

   Enable python setup.py test with pytest.
   -

   Remove the deprecated prefix= argument to ParseContext.closure().
   -

   Document that *Grako* may be used as a library (with no code generation)
   by compiling grammars to Grammar objects that can be used to parse any
   given input, much like Python's re does with regular expressions.
   -

   Refactored grammar so double naming (name1:name2:exp) is disallowed.

Grako 3.20.0 <https://pypi.python.org/pypi/grako/3.20.0>

*Grako* (for *grammar compiler*) is a tool that takes grammars in a
variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers
in Python.

*Grako* can also compile a grammar stored in a string into a
grako.grammars.Grammar object that can be used to parse any given input,
much like the *re* module does with regular expressions.
