Bumps pyparsing from 2.2.0 to 3.1.4.

Release notes

Sourced from pyparsing's releases.

Pyparsing 3.1.0a1

NOTE: In the future release 3.2.0, use of many of the pre-PEP8 methods (such as ParserElement.parseString) will start to raise DeprecationWarnings. 3.2.0 should get released some time later in 2023. I currently plan to completely drop the pre-PEP8 methods in pyparsing 4.0, though we won't see that release until at least late 2023 if not 2024. So there is plenty of time to convert existing parsers to the new function names before the old functions are completely removed. (Big help from Devin J. Pohly in structuring the code to enable this peaceful transition.)

Version 3.2.0 will also discontinue support for Python versions 3.6 and 3.7.

• API ENHANCEMENT: Optional(expr) may now be written as expr | ""

  This will make this code:

  "{" + Optional(Literal("A") | Literal("a")) + "}"
  

  writable as:

  "{" + (Literal("A") | Literal("a") | "") + "}"
  

  Some related changes implemented as part of this work:

  • Literal("") now internally generates an Empty() (and no longer raises an exception)
  • Empty is now a subclass of Literal

  Suggested by Antony Lee (issue #412), PR (#413) by Devin J. Pohly.

• Added new class property identifier to all Unicode set classes in pyparsing.unicode, using the class's values for cls.identchars and cls.identbodychars. Now Unicode-aware parsers that formerly wrote:

  ppu = pyparsing.unicode
  ident = Word(ppu.Greek.identchars, ppu.Greek.identbodychars)
  

  can now write:

  ident = ppu.Greek.identifier
  # or
  # ident = ppu.Ελληνικά.identifier
  

• Reworked delimited_list function into the new DelimitedList class. DelimitedList has the same constructor interface as delimited_list, and in this release, delimited_list changes from a function to a synonym for DelimitedList. delimited_list and the older delimitedList method will be deprecated in a future release, in favor of DelimitedList.

• Added new class method ParserElement.using_each, to simplify code that creates a sequence of Literals, Keywords, or other ParserElement subclasses.

  For instance, to define suppressable punctuation, you would previously write:

  LPAR, RPAR, LBRACE, RBRACE, SEMI = map(Suppress, "(){};")
  

  You can now write:

  LPAR, RPAR, LBRACE, RBRACE, SEMI = Suppress.using_each("(){};")
  

  using_each will also accept optional keyword args, which it will pass through to the class initializer. Here is an expression for single-letter variable names that might be used in an algebraic expression:

  algebra_var = MatchFirst(
      Char.using_each(string.ascii_lowercase, as_keyword=True)
  )

Changelog

Sourced from pyparsing's changelog.

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.
