Subject: how to find the position of each match within a string


Hi all,

I have  a small script to find a match. If a match is found I need to
print its position within the string. I try the String#index but it only
returns the first match. Any idea?

Thanks,

Li

irb(main):001:0> "ello-hello".scan('e') do |match|
irb(main):002:1*     p "ello-hello".index(match)
irb(main):003:1> end
0
0
=> "ello-hello"
irb(main):004:0>
