pyparsing-3.1.4 (Python module)

[Bruce Dubbs]

New point version.

Version 3.1.4 - August, 2024

• Fix to 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.

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.

• 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.

• 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.

• Updated railroad diagram generation for ZeroOrMore and OneOrMore expressions with stop_on expressions

• Added <META> tag to HTML generated for railroad diagrams to force UTF-8 encoding with older browsers, to better display Unicode parser characters.

• Fixed some cosmetics/bugs in railroad diagrams:
  • fixed groups being shown even when show_groups=False
  • show results names as quoted strings when show_results_names=True
  • only use integer loop counter if repetition > 2

• Some type annotations added for parse action related methods

• Added exception type to trace_parse_action exception output

• Added set_name calls to internal expressions generated in infix_notation, for improved railroad diagramming.

• delta_time, lua_parser, decaf_parser, and roman_numerals examples cleaned up to use latest PEP8 names and add minor enhancements.

• Fixed bug (and corresponding test code) in delta_time example that did not handle weekday references in time expressions (like "Monday at 4pm") when the weekday was the same as the current weekday.

• Minor performance speedup in trim_arity, to benefit any parsers using parse actions.

• Added early testing support for Python 3.13 with JIT enabled.
