From: shevegen@... Date: 2018-02-21T23:51:15+00:00 Subject: [ruby-core:85738] [Ruby trunk Bug#14539] Duplicate range in character class warning Issue #14539 has been updated by shevegen (Robert A. Heiler). Agreed. Your code did not use more than one \X so the warning is incorrect as it is (because you did not use more than one \X, so at best, it may have originated from elsehwere, which was not your fault then) - so it sounds like a bug IMO. Since some grapheme-specific code was added in 2.5.x, I believe this may be a reason for the behaviour change compared to ruby 2.4.x. ---------------------------------------- Bug #14539: Duplicate range in character class warning https://bugs.ruby-lang.org/issues/14539#change-70579 * Author: Anonymous * Status: Open * Priority: Normal * Assignee: * Target version: * ruby -v: >= 2.5.0 * Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN ---------------------------------------- ~~~ ruby #!/usr/bin/env ruby -w puts RUBY_VERSION puts "����".match?(/\X/).inspect puts '--------------' ~~~ ~~~ text 2.4.3 true -------------- 2.5.0 grapheme_warning.rb:3: warning: character class has duplicated range: /\X/ true -------------- 2.6.0 grapheme_warning.rb:3: warning: character class has duplicated range: /\X/ true -------------- ~~~ I don't think there's a duplicate range here, so there should not be a warning. -- https://bugs.ruby-lang.org/ Unsubscribe:
