Bumps pyparsing from 3.0.9 to 3.1.0.

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 3.1.0 - 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"])
