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

966 be a property list, consisting of alternating pairs of keys
967 (typically symbols or keywords) and values. Each iteration
968 processes one such pair out of LIST, assigning the two elements to
969 KEY and VALUE respectively. Malformed lists and circularities are
970 trapped as usual, and in addition, property lists with an odd number
971 of elements also signal an error.

1661 MANY means pass a vector of evaluated arguments,

1664 which contains the argument values.
