      • parseTypedArgList

        public static AttributeDict parseTypedArgList(ActionAST action,
                                              String s,
                                              Grammar g)
        Given an arg or retval scope definition list like Map , int[] j3, char *foo32[3] or int i=3, j=a[34]+20 convert to an attribute scope.

      • parseAttributeDef

        public static Attribute parseAttributeDef(ActionAST action,
                                          <any> decl,
                                          Grammar g)
        For decls like "String foo" or "char *foo32[]" compute the ID and type declarations. Also handle "int x=3" and 'T t = new T("foo")' but if the separator is ',' you cannot use ',' in the initvalue unless you escape use "\," escape.

      • splitDecls

        public static List<<any>> splitDecls(String s,
                                     int separatorChar)
        Given an argument list like x, (*a).foo(21,33), 3.2+1, '\n', "a,oo\nick", {bl, "fdkj"eck}, ["cat\n,", x, 43] convert to a list of attributes. Allow nested square brackets etc... Set separatorChar to ';' or ',' or whatever you want.

      • _splitArgumentList

        public static int _splitArgumentList(String actionText,
                                     int start,
                                     int targetChar,
                                     int separatorChar,
                                     List<<any>> args)
