# dumb question perhaps, but how do I do a Ruby based regex expression
# that takes the following as input and produces the following as
# output:
# INPUT: "#{some_string}"   # or perhaps if the # needs escaping this
# should be "\#{some_string}"
# OUTPUT: "some_string"
# i.e. what do I put in:  "#{some_string}".match("????")

something fr,

re=/\#\{(.*?)\}/
#=> /\#\{(.*?)\}/

s="\#{some_string}"
#=> "\#{some_string}"

s.match(re).captures
#=> ["some_string"]
