Version 3.1.4 - August, 2024

• Fixed a regression introduced in pyparsing 3.1.3, addition of a type annotation that referenced re.Pattern. Since this type was introduced in Python 3.7, using this type definition broke Python 3.6 installs of pyparsing 3.1.3. PR submitted by Felix Fontein, nice work!

Version 3.1.3 - August, 2024

• Added new Tag ParserElement, for inserting metadata into the parsed results. This allows a parser to add metadata or annotations to the parsed tokens. The Tag element also accepts an optional value parameter, defaulting to True. See the new tag_metadata.py example in the examples directory.

  Example:

    # add tag indicating mood
    end_punc = "." | ("!" + Tag("enthusiastic")))
    greeting = "Hello" + Word(alphas) + end_punc
  result = greeting.parse_string("Hello World.")
  print(result.dump())
  result = greeting.parse_string("Hello World!")
  print(result.dump())
  

  prints:

    ['Hello', 'World', '.']
  ['Hello', 'World', '!']
  
  enthusiastic: True
  

Added example mongodb_query_expression.py, to convert human-readable infix query expressions (such as a==100 and b>=200) and transform them into the equivalent query argument for the pymongo package ({'$and': [{'a': 100}, {'b': {'$gte': 200}}]}). Supports many equality and inequality operators - see the docstring for the transform_query function for more examples.

Fixed issue where PEP8 compatibility names for ParserElement static methods were not themselves defined as staticmethods. When called using a ParserElement instance, this resulted in a TypeError exception. Reported by eylenburg (#548).

To address a compatibility issue in RDFLib, added a property setter for the ParserElement.name property, to call ParserElement.set_name.

Modified ParserElement.set_name() to accept a None value, to clear the defined name and corresponding error message for a ParserElement.
