How to strip leading and trailing quote from string, in Ruby

Question

I want to strip leading and trailing quotes, in Ruby, from a string. The quote character will occur 0 or 1 time. For example, all of the following should be converted to f

Answer 1

I wanted the same but for slashes in url path, which can be /test/test/test/ (so that it has the stripping characters in the middle) and eventually came up with something like this to avoid regexps:

'/test/test/test/'.split('/').reject(|i| i.empty?).join('/')

Which in this case translates obviously to:

 '"foo,bar"'.split('"').select{|i| i != ""}.join('"')

or

'"foo,bar"'.split('"').reject{|i| i.empty?}.join('"')
