From: duerst@... Date: 2016-09-24T02:53:23+00:00 Subject: [ruby-core:77377] [Ruby trunk Feature#12786] String#casecmp? Issue #12786 has been updated by Martin D��rst. Can you describe exactly what String#casecmp? method would do? Does it only compare for equality (after case folding)? This proposal is interesting, because String#upcase/downcase/capitalize/swapcase now work for all of Unicode. But String#casecmp doesn't, because it would be a lot of additional work (and would depend on natural language) as to which string is larger or smaller. But that doesn't apply to String#casecmp?, so it could be made to work rather easily with all of Unicode. Essentially, the implementation would be something like ````ruby class String def casecomp? (other) downcase(:fold) == other.downcase(:fold) end end ```` ---------------------------------------- Feature #12786: String#casecmp? https://bugs.ruby-lang.org/issues/12786#change-60623 * Author: Ryan Ringler * Status: Open * Priority: Normal * Assignee: ---------------------------------------- Description I would find String#casecmp? convenience method handy. I don't believe I've ever called String#casecmp without chaining #zero? to the result. ```ruby 'abc'.casecmp?('ABC') #=> true 'abc'.casecmp?('DEF') #=> false ``` ---Files-------------------------------- string_casecmp_.patch (4.89 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
