Which Method called current method

Which Method Called current Method

I really wanted a way to determine, which method has called current method, for aiding in debugging purpose. Here is the way to do it in correct way finally:

def caller_method_name
    parse_caller(caller(2).first).last
end
def parse_caller(at)
    if /^(.+?):(\d+)(?::in `(.*)')?/ =~ at
        file = Regexp.last_match[1]
        line = Regexp.last_match[2].to_i
        method = Regexp.last_match[3]
        [file, line, method]
    end
end
