Issue #20469 has been updated by shan (Shannon Skipper). I just realized I filed my PR in the wrong place since JSON is a gem. (Sorry for the noise.) I closed the previous PR and opened one in the JSON gem repo. https://github.com/flori/json/pull/583 ---------------------------------------- Feature #20469: Add a JSON addition for Enumerator::ArithmeticSequence https://bugs.ruby-lang.org/issues/20469#change-108182 * Author: shan (Shannon Skipper) * Status: Open ---------------------------------------- There's a JSON addition for `Range` but one wasn't added for `Enumerator::ArithmeticSequence` when it was introduced. This little PR adds a JSON addition for ArithmeticSequence for parity with a normal Range. https://github.com/ruby/ruby/pull/10720/files ``` ruby ## # Already supported require 'json/add/range' (0..42).to_json ## # Proposed addition require 'json/add/arithmetic_sequence' ((0..42) % 3).to_json ``` I was curious about adding it to `add/core.rb` but it seems like that could be considered separately, especially since there are classes like Set that could also be considered for inclusion now that it's a core class. -- https://bugs.ruby-lang.org/
