From: mame@... Date: 2019-04-30T17:06:13+00:00 Subject: [ruby-core:92502] [Ruby trunk Bug#15745] There is no symmetry in the beginless range and the endless range using `Range#inspect` Issue #15745 has been updated by mame (Yusuke Endoh). Oops, I'm sorry, parentheses are not rendered in the result of `inspect`. Let me rephrase and include (3): (0) Keep the current behavior: `p (1..) #=> 1..`, `p (..1) #=> nil..1`, and `p (nil..nil) #=> nil..`. (1) Make all cases explicit: `p (1..) #=> 1..nil`, `p (..1) #=> nil..1`, and `p (nil..nil) #=> nil..nil`. (2) Omit all `nil`s except `(nil..nil)`: `p (1..) #=> 1..`, `p (..1) #=> ..1`, and `p (nil..nil) #=> nil..nil`. (3) Force to omit all `nil`s: `p (1..) #=> 1..`, `p (..1) #=> ..1`, and `p (nil..nil) #=> ..`. I'd like to avoid "don't care". Even if we don't care, we need to choose one of them. ---------------------------------------- Bug #15745: There is no symmetry in the beginless range and the endless range using `Range#inspect` https://bugs.ruby-lang.org/issues/15745#change-77863 * Author: koic (Koichi ITO) * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: ruby 2.7.0dev (2019-04-03 trunk 67423) [x86_64-darwin17] * Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- The following commit introduces beginless range. https://github.com/ruby/ruby/commit/95f7992b89efd35de6b28ac095c4d3477019c583 ``` % ruby -v ruby 2.7.0dev (2019-04-03 trunk 67423) [x86_64-darwin17] ``` There is no symmetry with endless range when using `Range#inspect` method. ``` (1..).inspect # => "1.."
