Issue #20770 has been updated by ufuk (Ufuk Kayserilioglu). I tend to agree with @Dan0042 on this one, this seems to go against the nature of Ruby. In Ruby, an expression like `URI.parse(it)` is always eagerly evaluated, except when it is inside a block. This is not true in other languages; ones that make a distinction between `Foo.bar` and `Foo.bar()`, for example. This proposal, however, is adding a new conceptual context in which the evaluation would be delayed, which would be in a sequence of pipeline operators. I am not sure if I like that, to be honest. In contrast, I like @jeremyevans0 's suggestion to add syntactic sugar to `.then` method in the form of `.{}` which still keeps the block as the only construct that would delay the evaluation of methods, and it allows the use of numbered block parameters and/or `it` inside such blocks without any other changes to the language. ---------------------------------------- Feature #20770: A *new* pipe operator proposal https://bugs.ruby-lang.org/issues/20770#change-110001 * Author: AlexandreMagro (Alexandre Magro) * Status: Open ---------------------------------------- Hello, This is my first contribution here. I have seen previous discussions around introducing a pipe operator, but it seems the community didn't reach a consensus. I would like to revisit this idea with a simpler approach, more of a syntactic sugar that aligns with how other languages implement the pipe operator, but without making significant changes to Ruby's syntax. Currently, we often write code like this: ```ruby value = half(square(add(value, 3))) ``` We can achieve the same result using the `then` method: ```ruby value = value.then { add(_1, 3) }.then { square(_1) }.then { half(_1) } ``` While `then` helps with readability, we can simplify it further using the proposed pipe operator: ```ruby value = add(value, 3) |> square(_1) |> half(_1) ``` Moreover, with the upcoming `it` feature in Ruby 3.4 (#18980), the code could look even cleaner: ```ruby value = add(value, 3) |> square(it) |> half(it) ``` This proposal uses the anonymous block argument `(_1)`, and with `it`, it simplifies the code without introducing complex syntax changes. It would allow us to achieve the same results as in other languages that support pipe operators, but in a way that feels natural to Ruby, using existing constructs like `then` underneath. I believe this operator would enhance code readability and maintainability, especially in cases where multiple operations are chained together. Thank you for considering this proposal! -- https://bugs.ruby-lang.org/
