        public static java.lang.String processMacros​(java.lang.String consequence)

      • delimitExpressions

        public static java.lang.String delimitExpressions​(java.lang.String s)
        Allows newlines to demarcate expressions, as per MVEL command line. If expression spans multiple lines (ie inside an unbalanced bracket) then it is left alone. Uses character based iteration which is at least an order of magnitude faster then a single simple regex.
