666 /*---------------------- list traversal macros -------------------------*/
668 /* Note: These macros are for traversing through a list in some format,
669 and executing code that you specify on each member of the list.
671 There are two kinds of macros, those requiring surrounding braces, and
672 those not requiring this. Which type of macro will be indicated.
673 The general format for using a brace-requiring macro is
676 LIST_LOOP_3 (elt, list, tail)
683 LIST_LOOP_3 (elt, list, tail)
689 You can put variable declarations between the brace and beginning of
690 macro, but NOTHING ELSE.
692 The brace-requiring macros typically declare themselves any arguments
693 that are initialized and iterated by the macros. If for some reason
694 you need to declare these arguments yourself (e.g. to do something on
695 them before the iteration starts, use the _NO_DECLARE versions of the
699 /* There are two basic kinds of macros: those that handle "internal" lists
700 that are known to be correctly structured (i.e. first element is a cons
701 or nil, and the car of each cons is also a cons or nil, and there are
702 no circularities), and those that handle "external" lists, where the
703 list may have any sort of invalid formation. This is reflected in
704 the names: those with "EXTERNAL_" work with external lists, and those
705 without this prefix work with internal lists. The internal-list
706 macros will hit an assertion failure if the structure is ill-formed;
707 the external-list macros will signal an error in this case, either a
708 malformed-list error or a circular-list error.
710 Note also that the simplest external list iterator, EXTERNAL_LIST_LOOP,
711 does *NOT* check for circularities. Therefore, make sure you call
712 QUIT each iteration or so. However, it's probably easier just to use
713 EXTERNAL_LIST_LOOP_2, which is easier to use in any case.
716 /* LIST_LOOP and EXTERNAL_LIST_LOOP are the simplest macros. They don't
717 require brace surrounding, and iterate through a list, which may or may
718 not known to be syntactically correct. EXTERNAL_LIST_LOOP is for those
719 not known to be correct, and it detects and signals a malformed list
720 error when encountering a problem. Circularities, however, are not
721 handled, and cause looping forever, so make sure to include a QUIT.
722 These functions also accept two args, TAIL (set progressively to each
723 cons starting with the first), and LIST, the list to iterate over.
724 TAIL needs to be defined by the program.
726 In each iteration, you can retrieve the current list item using XCAR
727 (tail), or destructively modify the list using XSETCAR (tail,
730 #define LIST_LOOP(tail, list) \
735 #define EXTERNAL_LIST_LOOP(tail, list) \
736 for (tail = list; !NILP (tail); tail = XCDR (tail)) \
738 signal_malformed_list_error (list); \
741 /* The following macros are the "core" macros for list traversal.
743 *** ALL OF THESE MACROS MUST BE DECLARED INSIDE BRACES -- SEE ABOVE. ***
745 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used
746 macros. They take two arguments, an element variable ELT and the list
747 LIST. ELT is automatically declared, and set to each element in turn
750 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third
751 argument TAIL, another automatically-declared variable. At each iteration,
752 this one points to the cons cell for which ELT is the car.
754 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional
755 LEN argument, again automatically declared, which counts the number of
756 iterations gone by. It is 0 during the first iteration.
758 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none
759 of the variables are automatically declared, and so you need to declare
760 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.)

977 trapped as usual, and in addition, property lists with an odd number

1668 MANY means pass a vector of evaluated arguments,
