String.scan() doesn't set $1, $2, ...
-------------------------------------
Key: JRUBY-872
URL: http://jira.codehaus.org/browse/JRUBY-872
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 0.9.9, JRuby 0.9.8
Environment: Mac OS X 10.4.9, running Java 1.5.0_07, and JRuby 0.9.8
and 0.9.9
Reporter: Andrew Geweke
The following snippet of Ruby code, on MRI (native Ruby), prints:
Scanned: oo
Matched: oo
...but JRuby prints:
Scanned:
Matched: oo
JRuby is not setting $1 correctly after String.scan is called. (This is
assuming the canonical spec of how Ruby works is MRI, which is my
understanding.)
I will try to create a testcase and patch and upload them here shortly, but I
wanted to make sure the bug didn't slip through the cracks in any case...
-------- snippet follows ----------
TestString = "foobar"
TestString.scan(/(o+)/)
puts "Scanned: #{$1}"
TestString =~ /(o+)/
puts "Matched: #{$1}"
