Issue #21190 has been updated by jeremyevans0 (Jeremy Evans). You can implement this more easily using named captures: ```ruby /(?<country_code>\d{2})(?<area_code>\d{2})(?<number>\d{9})/ =~ "5586987654321" country_code # => "55" area_code # => "86" number # => "987654321" ``` I think proper use of named captures should handle most cases where you would want to use the proposed `MatchData#deconstruct`. The remaining cases would be when you are passing MatchData as an argument to or result of a method call. If we did want to implement this, it's questionable to me whether `MatchData#deconstruct` should operate like `MatchData#to_a` or `MatchData#captures` (your example implies `captures` would be a more useful behavior for that use case). ---------------------------------------- Feature #21190: Proposal for the Deconstruct Method in the MatchData Class https://bugs.ruby-lang.org/issues/21190#change-112365 * Author: aristotelesbr (Aristóteles Costa) * Status: Open ---------------------------------------- ## Context: The MatchData class currently lacks the deconstruct method, which is necessary for extracting values from a string using pattern matching in Ruby. ## Current Extraction Method Currently, extraction can be done as follows: ```rb result = /(\d{2})(\d{2})(\d{9})/.match("5586987654321") puts result[1] # => "55" puts result[2] # => "86" puts result[3] # => "987654321" ``` ## Proposed Solution: Implement the deconstruct method in the MatchData class to allow conversion of the MatchData object into an array, enabling deconstruction of its components. ```rb class MatchData def deconstruct self.to_a end end result = /(\d{2})(\d{2})(\d{9})/.match("5586987654321") result in [_ , country_code, area_code, number] puts country_code # => "55" puts area_code # => "86" puts number # => "987654321" ``` -- https://bugs.ruby-lang.org/
