Bump pyparsing from 2.2.0 to 3.2.0

[dependabot]

Bumps pyparsing from 2.2.0 to 3.2.0.

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 3.2.0 - October, 2024

• Discontinued support for Python 3.6, 3.7, and 3.8. Adopted new Python features from Python versions 3.7-3.9:

  • Updated type annotations to use built-in container types instead of names imported from the typing module (e.g., list[str] vs List[str]).
  • Reworked portions of the packrat cache to leverage insertion-preserving ordering in dicts (including removal of uses of OrderedDict).
  • Changed pdb.set_trace() call in ParserElement.set_break() to breakpoint().
  • Converted typing.NamedTuple to dataclasses.dataclass in railroad diagramming code.
  • Added from __future__ import annotations to clean up some type annotations. (with assistance from ISyncWithFoo, issue #535, thanks for the help!)

• POSSIBLE BREAKING CHANGES

  The following bugfixes may result in subtle changes in the results returned or exceptions raised by pyparsing.

  • Fixed code in ParseElementEnhance subclasses that replaced detailed exception messages raised in contained expressions with a less-specific and less-informative generic exception message and location.

    If your code has conditional logic based on the message content in raised ParseExceptions, this bugfix may require changes in your code.

  • Fixed bug in transform_string() where whitespace in the input string was not properly preserved in the output string.

    If your code uses transform_string, this bugfix may require changes in your code.

  • Fixed bug where an IndexError raised in a parse action was incorrectly handled as an IndexError raised as part of the ParserElement parsing methods, and reraised as a ParseException. Now an IndexError that raises inside a parse action will properly propagate out as an IndexError. (Issue #573, reported by August Karlstedt, thanks!)

    If your code raises IndexErrors in parse actions, this bugfix may require changes in your code.

• FIXES AND NEW FEATURES

  • Added type annotations to remainder of pyparsing package, and added mypy run to tox.ini, so that type annotations are now run as part of pyparsing's CI. Addresses Issue #373, raised by Iwan Aucamp, thanks!

  • Exception message format can now be customized, by overriding ParseBaseException.format_message:
