Update pyparsing requirement from <3.1,>=2.4.2 to >=2.4.2,<3.2

[dependabot]

Updates the requirements on pyparsing to permit the latest version.

Changelog

Sourced from pyparsing's changelog.

Version 3.1.0 - June, 2023

• Added tag_emitter.py to examples. This example demonstrates how to insert tags into your parsed results that are not part of the original parsed text.

Version 3.1.0b2 - May, 2023

• Updated create_diagram() code to be compatible with railroad-diagrams package version 3.0. Fixes Issue #477 (railroad diagrams generated with black bars), reported by Sam Morley-Short.

• Fixed bug in NotAny, where parse actions on the negated expr were not being run. This could cause NotAny to incorrectly fail if the expr would normally match, but would fail to match if a condition used as a parse action returned False. Fixes Issue #482, raised by byaka, thank you!

• Fixed create_diagram() to accept keyword args, to be passed through to the template.render() method to generate the output HTML (PR submitted by Aussie Schnore, good catch!)

• Fixed bug in python_quoted_string regex.

• Added examples/bf.py Brainf*ck parser/executor example. Illustrates using a pyparsing grammar to parse language syntax, and attach executable AST nodes to the parsed results.

Version 3.1.0b1 - April, 2023

• Added support for Python 3.12.

• API CHANGE: A slight change has been implemented when unquoting a quoted string parsed using the QuotedString class. Formerly, when unquoting and processing whitespace markers such as \t and \n, these substitutions would occur first, and then any additional '' escaping would be done on the resulting string. This would parse "\n" as "<newline>". Now escapes and whitespace markers are all processed in a single pass working left to right, so the quoted string "\n" would get unquoted to "\n" (a backslash followed by "n"). Fixes issue #474 raised by jakeanq, thanks!

• Added named field "url" to pyparsing.common.url, returning the entire parsed URL string.

• Fixed bug when parse actions returned an empty string for an expression that had a results name, that the results name was not saved. That is:

  expr = Literal("X").add_parse_action(lambda tokens: "")("value")
  result = expr.parse_string("X")
  print(result["value"])
  

... (truncated)
