[dependabot]

Bumps regexp_parser from 2.1.1 to 2.4.0.

Changelog

Sourced from regexp_parser's changelog.

[2.4.0] - 2022-05-09 - Janosch Müller

Fixed

• fixed interpretation of + and ? after interval quantifiers ({n,n})
  • they used to be treated as reluctant or possessive mode indicators
  • however, Ruby does not support these modes for interval quantifiers
  • they are now treated as chained quantifiers instead, as Ruby does it
  • c.f. #3
• fixed Expression::Base#nesting_level for some tree rewrite cases
  • e.g. the alternatives in /a|[b]/ had an inconsistent nesting_level
• fixed Scanner accepting invalid posix classes, e.g. [[:foo:]]
  • they raise a SyntaxError when used in a Regexp, so could only be passed as String
  • they now raise a Regexp::Scanner::ValidationError in the Scanner

Added

• added Expression::Base#== for (deep) comparison of expressions

• added Expression::Base#parts

  • returns the text elements and subexpressions of an expression
  • e.g. parse(/(a)/)[0].parts # => ["(", #<Literal @text="a"...>, ")"]

• added Expression::Base#te (a.k.a. token end index)

  • Expression::Subexpression always had #te, only terminal nodes lacked it so far

• made some Expression::Base methods available on Quantifier instances, too

  • #type, #type?, #is?, #one_of?, #options, #terminal?
  • #base_length, #full_length, #starts_at, #te, #ts, #offset
  • #conditional_level, #level, #nesting_level , #set_level
  • this allows a more unified handling with Expression::Base instances

• allowed Quantifier#initialize to take a token and options Hash like other nodes

• added a deprecation warning for initializing Quantifiers with 4+ arguments:

  Calling Expression::Base#quantify or Quantifier.new with 4+ arguments is deprecated.

  It will no longer be supported in regexp_parser v3.0.0.

  Please pass a Regexp::Token instead, e.g. replace type, text, min, max, mode with ::Regexp::Token.new(:quantifier, type, text). min, max, and mode will be derived automatically.

  This is consistent with how Expression::Base instances are created.

[2.3.1] - 2022-04-24 - Janosch Müller

Fixed

• removed five inexistent unicode properties from Syntax#features
  • these were never supported by Ruby or the Regexp::Scanner
  • thanks to Markus Schirp for the report
