A ruby-esque "split" that respects word groups

Greetings friends,

I wondering if anyone here has some Ruby-fu they can share with WRT
for following problem. I've toyed with this today and don't like my
solution so I thought I'd run it by y'all. In summary, suppose we
have the following input, say to a command line interpreter:

foo bar "baz 42" "matz ruby yarv" jruby

Running split on this string, of course, yeilds:

['foo', 'bar', '"baz', '42"', '"matz', 'ruby', 'yarv"', 'jruby']

What I'd like instead is a "split" that respects the quoted word
groupings, which would result in the following instead:

['foo', 'bar', 'baz 42', 'matz ruby yarv', 'jruby']

Thanks in advance for any ideas you can lend!

Cheers,

Ken

My cleanest solution thus far, which does not properly handled nested
quotes:

a = "foo 'bar baz bim' 42 'java jruby jar'"
puts a.split("'").each { |b| b.strip! }

Not sure if this is the best way, but just doing this off the cuff and it
works:

scan(/\w+|\".+?\"/)

Hope that helps.
