From: shannonskipper@... Date: 2019-06-16T15:29:45+00:00 Subject: [ruby-core:93188] [Ruby trunk Feature#15799] pipeline operator Issue #15799 has been updated by shan (Shannon Skipper). Seeing `|>` my assumption would be that you could use it in the functional style, so you could do: ``` ruby 42 |> Integer(exception: false) |> Math.sqrt ``` Instead of: ```ruby Math.sqrt(Integer(42, exception: false)) ``` Since this seems like the opposite direction of `|>`, might `<|` be an acceptable alternative to `>>>`? ```ruby 1.. <| take 10 <| map {|e| e*2} <| (x) #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20] 1.. |> take 10 |> map {|e| e*2} |> (x) #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20] 1.. >>> take 10 >>> map {|e| e*2} >>> (x) #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20] ``` ---------------------------------------- Feature #15799: pipeline operator https://bugs.ruby-lang.org/issues/15799#change-78629 * Author: nobu (Nobuyoshi Nakada) * Status: Closed * Priority: Normal * Assignee: * Target version: ---------------------------------------- Implemented the pipeline operator `|>`, a topic of "ruby committers vs the world" in RubyKaigi 2019. Also a casual idea of rightward assignment. ```ruby 1.. |> take 10 |> map {|e| e*2} |> (x) p x #=> [2, 4, 6, 8, 10, 12, 14, 16, 18, 20] ``` https://github.com/nobu/ruby/tree/feature/pipeline -- https://bugs.ruby-lang.org/ Unsubscribe:
