Counting .each

ruby-talk

Is there some equivalent to file.lineno when using array.each? Eg, if I
am iterating thru an array of strings searching for a pattern, and I
want to save the current array index, do I have to do this:

count = 0
array.each { |e|
    finds.push count if e =~ /pattern/
    count += 1
}

or is there a "array.currentindex"? I guess I could use each_index...

array.each_with_index do | e, count|
  finds.push count if e =~ /pattern/
end
