I think you want: "a b c".scanf("%s %s %s") ---------------------------------------- Bug #12035: scanf suspicious results. https://bugs.ruby-lang.org/issues/12035#change-56962 * Author: Peter Camilleri * Status: Open * Priority: Normal * Assignee: * ruby -v: ruby 2.2.3p173 (2015-08-18 revision 51636) [i386-cygwin], ruby 2.1.6p336 (2015-04-13 revision 50298) [i386-mingw32], and ruby 1.9.3p484 (2013-11-22) [i386-mingw32] * Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN ---------------------------------------- The code: 'a b c'.scanf('%[a] %[b] %[c]') yields the result: ["a"] and not ["a","b","c"] as expected. So far it seems that when sets of characters are used, only the first one in the parse specification string actually returns any data. -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request / ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
