From: Greg.mpls@... Date: 2017-09-30T12:53:28+00:00 Subject: [ruby-core:83066] [Ruby trunk Feature#13395] Add a method to check for not nil Issue #13395 has been updated by MSP-Greg (Greg L). I believe the english equivalent to `not_nil` would be `exist` (instead of exists, to follow prev use). I believe core only uses `exist?` with `Dir`, `File`, and `FileTest`. Having it would allow showing the standard case first in an if-else-end structure, given that unless-else-end may be considered 'strange' code. Also, I'm sure many of us have used a tri-state nil/false/true variable when it is helpful. ---------------------------------------- Feature #13395: Add a method to check for not nil https://bugs.ruby-lang.org/issues/13395#change-67006 * Author: JustJosh (Joshua Stowers) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- There does not seem to be a method in Ruby to check if an object is *not* nil. Such a method could help with readability. Example: > ~~~ ruby > array = [1, 'dog', nil] > array.count(&:not_nil?) > ~~~ > vs > ~~~ ruby > array = [1, 'dog', nil] > array.reject(&:nil?).count > ~~~ -- https://bugs.ruby-lang.org/ Unsubscribe:
