Bump pyparsing from 3.0.7 to 3.1.2

[dependabot]

Bumps pyparsing from 3.0.7 to 3.1.2.

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 3.1.2 - March, 2024

• Added ieee_float expression to pyparsing.common, which parses float values, plus "NaN", "Inf", "Infinity". PR submitted by Bob Peterson (#538).

• Updated pep8 synonym wrappers for better type checking compatibility. PR submitted by Ricardo Coccioli (#507).

• Fixed empty error message bug, PR submitted by InSync (#534). This should return pyparsing's exception messages to a former, more helpful form. If you have code that parses the exception messages returned by pyparsing, this may require some code changes.

• Added unit tests to test for exception message contents, with enhancement to pyparsing.testing.assertRaisesParseException to accept an expected exception message.

• Updated example select_parser.py to use PEP8 names and added Groups for better retrieval of parsed values from multiple SELECT clauses.

• Added example email_address_parser.py, as suggested by John Byrd (#539).

• Added example directx_x_file_parser.py to parse DirectX template definitions, and generate a Pyparsing parser from a template to parse .x files.

• Some code refactoring to reduce code nesting, PRs submitted by InSync.

• All internal string expressions using '%' string interpolation and str.format() converted to f-strings.

Version 3.1.1 - July, 2023

• Fixed regression in Word(min), reported by Ricardo Coccioli, good catch! (Issue #502)

• Fixed bug in bad exception messages raised by Forward expressions. PR submitted by Kyle Sunden, thanks for your patience and collaboration on this (#493).

• Fixed regression in SkipTo, where ignored expressions were not checked when looking for the target expression. Reported by catcombo, Issue #500.

• Fixed type annotation for enable_packrat, PR submitted by Mike Urbach, thanks! (Issue #498)

• Some general internal code cleanup. (Instigated by Michal Čihař, Issue #488)

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.
