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 can use gsub to search for the leading or trailing quote and replace it with an empty string:

s = "\"foo,bar\""
s.gsub!(/^\"|\"?$/, '')

As suggested by comments below, a better solution is:

s.gsub!(/\A"|"\Z/, '')
