I do not feel this proposal to be natural any more. Please close this issue. ---------------------------------------- Feature #10240: `String#to_a` https://bugs.ruby-lang.org/issues/10240#change-83628 * Author: sawa (Tsuyoshi Sawada) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- I often want to exclude the empty strings from an array of strings. A use case is to join an array of strings with `", "`, removing the empty ones, as follows: ```ruby ["Foo", "", "Bar"].reject(&:empty?).join(", ") # => "Foo, Bar" ``` In a similar situation with arrays of arrays, the empty ones can be excluded by using `*` and `Array#to_a`: ```ruby [*[1, 2], *[], *[3, 4]] # => [1, 2, 3, 4] ``` I would like to propose `String#to_a` defined as follows: ```ruby class String def to_a; empty? ? [] : [self] end end ``` Then we can do: ```ruby [*"Foo", *"", *"Bar"].join(", ") ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
