Changelog

Sourced from regexp_parser's changelog.

[2.8.0] - 2023-04-17 - Janosch Müller

Added

• Regexp::Expression::Shared#ends_at
  • e.g. parse(/a +/x)[0].ends_at # => 3
  • e.g. parse(/a +/x)[0].ends_at(include_quantifier = false) # => 1
• Regexp::Expression::Shared#{capturing?,comment?}
  • previously only available on capturing and comment groups
• Regexp::Expression::Shared#{decorative?}
  • true for decorations: comment groups as well as comments and whitespace in x-mode
• Regexp::Expression::Shared#parent
• new format argument :original for Regexp::Expression::Base#to_s
  • includes decorative elements between node and its quantifier
  • e.g. parse(/a (?#comment) +/x)[0].to_s(:original) # => "a (?#comment) +"
  • using it is not needed when calling Root#to_s as Root can't be quantified
• support calling Subexpression#{each_expression,flat_map} with a one-argument block
  • in this case, only the expressions are passed to the block, no indices
• support calling test methods at Expression class level
  • capturing?, comment?, decorative?, referential?, terminal?
  • e.g. Regexp::Expression::CharacterSet.terminal? # => false

Fixed

• Regexp::Expression::Shared#full_length with whitespace before quantifier
  • e.g. parse(/a +/x)[0].full_length used to yield 2, now it yields 3
• Subexpression#to_s output with children with whitespace before their quantifier
  • e.g. parse(/a + /x).to_s used to yield "a+ ", now it yields "a + "
  • calling #to_s on sub-nodes still omits such decorative interludes by default
    • use new #to_s format :original to include it
    • e.g. parse(/a + /x)[0].to_s(:original) # => "a +"
• fixed Subexpression#te behaving differently from other expressions
  • only Subexpression#te used to include the quantifier
  • now #te is the end index without quantifier, as for other expressions
• fixed NoMethodError when calling #starts_at or #ts on empty sequences
  • e.g. Regexp::Parser.parse(/|/)[0].starts_at
  • e.g. Regexp::Parser.parse(/[&&]/)[0][0].starts_at
• fixed nested comment groups breaking local x-options
  • e.g. in /(?x:(?#hello)) /, the x-option wrongly applied to the whitespace
• fixed nested comment groups breaking conditionals
  • e.g. in /(a)(?(1)b|c(?#hello)d)e/, the 2nd conditional branch included "e"
• fixed quantifiers after comment groups being mis-assigned to that group
  • e.g. in /a(?#foo){3}/ (matches 'aaa')
• fixed Scanner accepting two cases of invalid Regexp syntax
  • unmatched closing parentheses ()) and k-backrefs with number 0 (\k<0>)
  • these are a SyntaxError in Ruby, so could only be passed as a String
  • they now raise a Regexp::Scanner::ScannerError
• fixed some scanner errors not inheriting from Regexp::Scanner::ScannerError
• reduced verbosity of inspect / pretty print output
