From: matz@... Date: 2017-02-28T03:13:44+00:00 Subject: [ruby-core:79811] [Ruby trunk Feature#13260][Feedback] Kernel#Boolean Issue #13260 has been updated by Yukihiro Matsumoto. Status changed from Open to Feedback The proposal is still vague, especially when `strict: false`. The criteria are totally culture dependent. "yes" may be true for English speaking people, but what about "������" (Japanese) or "Ja" (German)? The list would go on. Until the ambiguity resolved, I am against the proposal. Matz. ---------------------------------------- Feature #13260: Kernel#Boolean https://bugs.ruby-lang.org/issues/13260#change-63242 * 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:
