From: nobu@... Date: 2017-04-26T01:03:03+00:00 Subject: [ruby-core:80864] [Ruby trunk Feature#12944] Change Kernel#warn to call Warning.warn Issue #12944 has been updated by nobu (Nobuyoshi Nakada). Nitpicking an edge case, these two are different. ```ruby puts "foo", "" #=> "foo\n" and "\n" ``` ```ruby puts ["foo", ""].join("\n") #=> "foo\n" ``` ---------------------------------------- Feature #12944: Change Kernel#warn to call Warning.warn https://bugs.ruby-lang.org/issues/12944#change-64472 * Author: jeremyevans0 (Jeremy Evans) * Status: Closed * Priority: Normal * Assignee: * Target version: ---------------------------------------- Currently, Kernel#warn is basically the same as $stderr.puts. With the new Warning.warn support in ruby 2.4, it makes sense for Kernel#warn to call Warning.warn, otherwise you will not be able to use Warning.warn to filter/process warning messages generated by Kernel#warn. The Kernel#warn API is different than the Warning.warn API, the attached patch tries to get similar behavior, but there are probably corner cases where the behavior is different. ---Files-------------------------------- 0001-Change-Kernel-warn-to-call-Warning.warn.patch (1.88 KB) 0001-Change-Kernel-warn-to-call-Warning.warn.patch (1.89 KB) 0001-Change-Kernel-warn-to-call-Warning.warn.patch (2.36 KB) 0001-Change-Kernel-warn-to-call-Warning.warn.patch (2.3 KB) 0001-Change-Kernel-warn-to-call-Warning.warn.patch (3.23 KB) 0001-Restore-behavior-of-Kernel-warn-accepting-arrays-arg.patch (1.23 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
