From: sawadatsuyoshi@... Date: 2017-02-28T06:20:31+00:00 Subject: [ruby-core:79813] [Ruby trunk Feature#13260] Kernel#Boolean Issue #13260 has been updated by Tsuyoshi Sawada. I agree that the proposal was vague. Instead of using `strict`, perhaps we can pass an argument or arguments expressing the language/mode that we want to allow. ```ruby Boolean("������", allow: ["JA", "EN"]) ``` ---------------------------------------- Feature #13260: Kernel#Boolean https://bugs.ruby-lang.org/issues/13260#change-63248 * Author: Tsuyoshi Sawada * Status: Feedback * Priority: Normal * Assignee: * Target version: ---------------------------------------- I think we have lots of occasions to receive a `true` or `false` value as a string input, and want to convert it to `true` or `false`. Perhaps we can have a method `Kernel#Boolean` in a similar spirit to `Kernel#Integer` and its kins, which takes an optional keyword argument `exception` (similar to https://bugs.ruby-lang.org/issues/12732) and `strict` (defaulted to true). ```ruby Boolean("true") # => true Boolean("false") # => false Boolean("foo") # => ArgumentError Boolean("foo", exception: nil) # => nil Boolean("1") # => ArgumentError Boolean("1", strict: false) # => true Boolean("yes", strict: false) # => true Boolean("0", strict: false) # => false Boolean("no", strict: false) # => false Boolean("foo", strict: false, exception: nil) # => nil ``` -- https://bugs.ruby-lang.org/ Unsubscribe:
