From: peter.c.camilleri@... Date: 2016-02-13T16:22:36+00:00 Subject: [ruby-core:73793] [Ruby trunk Bug#12035] scanf suspicious results. Issue #12035 has been updated by Peter Camilleri. That is what is so perplexing. The format I used was '%[a] %[b] %[c]' Please note the explicit spaces between the formant elements. The docs for scanf state that "White space in the format string matches any amount of white space" ---------------------------------------- Bug #12035: scanf suspicious results. https://bugs.ruby-lang.org/issues/12035#change-56974 * 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:
