first, last = '20-30'.split("-")
first.to_i .. last.to_i
#=> 20..30

Or:

string="20-30"
Range.new(*(string.split('-',2).map{|s|s.to_i}))

in English, split the string into at most two parts at the '-', map
those parts as integers, and use them to build a new Range.

Hi --

Or:
range = string.match(/(\d+)-(\d+)/) and ($1.to_i .. $2.to_i)

Or:

range = Range.new(*str.scanf("%d-%d"))
