Subject: [ruby-core:50879] [ruby-trunk - Bug #7558] Small docs bug for Regexp::union


Issue #7558 has been updated by zzak (Zachary Scott).


For what it's worth, here is the original patch: https://github.com/ruby/ruby/commit/cf9bdd0

Not sure what revision that is though. And seeing as how it was originally committed 5 years ago, I'm surprised this bug still exists.

Steve, only documentation I found on backporting: https://bugs.ruby-lang.org/projects/ruby/wiki/HowToBackport

Bug #7558: Small docs bug for Regexp::union
https://bugs.ruby-lang.org/issues/7558#change-34712

ruby -v: ruby 1.9.3p125 (2012-02-16 revision 34643) [x86_64-darwin12.2.0]


The docs for Regexp::union (http://ruby-doc.org/core-1.9.3/Regexp.html#method-c-union) state:

Regexp.union(/dogs/, /cats/)        #=> /(?-mix:dogs)|(?i-mx:cats)/

This is, however, incorrect, /cats/ doesn't have the /i flag, either it should be added or the expected result should be changed.
