I feel it can always convert to Hash because even if it doesn't use named captures, the numbering is 1-origin. ``` irb(main):001:0> /(a)(b)(c)/.match("abc") => #<MatchData "abc" 1:"a" 2:"b" 3:"c"> irb(main):002:0> /(a)(b)(c)/.match("abc").to_h => {1=>"a", 2=>"b", 3=>"c"} ``` ---------------------------------------- Feature #11999: MatchData#to_h to get a Hash from named captures https://bugs.ruby-lang.org/issues/11999#change-56199 * Author: sorah Shota Fukumori * Status: Open * Priority: Normal * Assignee: ---------------------------------------- ~~~ class MatchData def to_h self.names.map { |n| [n, self[n]] }.to_h end end p '12'.match(/(?<a>.)(?<b>.)(?<c>.)?/).to_h #=> {"a"=>"1", "b"=>"2", "c"=>nil} ~~~ Sometimes I want to get a Hash from named capture, but currently I have to use #names + #captures. How about adding MatchData#to_h for convenience way? ---Files-------------------------------- 11999.diff (2.77 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
