pyparsing 3.1.2

Pyparsing 3.1.2

on Python PyPI

Support for Python 3.13.

Added ieee_float expression to pyparsing.common, which parses float values, plus "NaN", "Inf", "Infinity". PR submitted by Bob Peterson (#538).

Updated pep8 synonym wrappers for better type checking compatibility. PR submitted by Ricardo Coccioli (#507).

Fixed empty error message bug, PR submitted by InSync (#534). This should return pyparsing's exception messages to a former, more helpful form. If you have code that parses the exception messages returned by pyparsing, this may require some code changes.

Added unit tests to test for exception message contents, with enhancement to pyparsing.testing.assertRaisesParseException to accept an expected exception message.

Updated example select_parser.py to use PEP8 names and added Groups for better retrieval of parsed values from multiple SELECT clauses.

Added example email_address_parser.py, as suggested by John Byrd (#539).

Added example directx_x_file_parser.py to parse DirectX template definitions, and generate a Pyparsing parser from a template to parse .x files.

Some code refactoring to reduce code nesting, PRs submitted by InSync.

All internal string expressions using '%' string interpolation and str.format() converted to f-strings.
