694 and executing code that you specify on each member of the list.
696 There are two kinds of macros, those requiring surrounding braces, and
697 those not requiring this. Which type of macro will be indicated.
698 The general format for using a brace-requiring macro is
701 LIST_LOOP_3 (elt, list, tail)
708 LIST_LOOP_3 (elt, list, tail)
714 You can put variable declarations between the brace and beginning of
715 macro, but NOTHING ELSE.
717 The brace-requiring macros typically declare themselves any arguments
718 that are initialized and iterated by the macros. If for some reason
719 you need to declare these arguments yourself (e.g. to do something on
720 them before the iteration starts, use the _NO_DECLARE versions of the
724 /* There are two basic kinds of macros: those that handle "internal" lists
725 that are known to be correctly structured (i.e. first element is a cons
726 or nil, and the car of each cons is also a cons or nil, and there are
727 no circularities), and those that handle "external" lists, where the
728 list may have any sort of invalid formation. This is reflected in
729 the names: those with "EXTERNAL_" work with external lists, and those
730 without this prefix work with internal lists. The internal-list
731 macros will hit an assertion failure if the structure is ill-formed;
732 the external-list macros will signal an error in this case, either a
733 malformed-list error or a circular-list error.
735 Note also that the simplest external list iterator, EXTERNAL_LIST_LOOP,
736 does *NOT* check for circularities. Therefore, make sure you call
737 QUIT each iteration or so. However, it's probably easier just to use
738 EXTERNAL_LIST_LOOP_2, which is easier to use in any case.
741 /* LIST_LOOP and EXTERNAL_LIST_LOOP are the simplest macros. They don't
742 require brace surrounding, and iterate through a list, which may or may
743 not known to be syntactically correct. EXTERNAL_LIST_LOOP is for those
744 not known to be correct, and it detects and signals a malformed list
745 error when encountering a problem. Circularities, however, are not
746 handled, and cause looping forever, so make sure to include a QUIT.
747 These functions also accept two args, TAIL (set progressively to each
748 cons starting with the first), and LIST, the list to iterate over.
749 TAIL needs to be defined by the program.
751 In each iteration, you can retrieve the current list item using XCAR
752 (tail), or destructively modify the list using XSETCAR (tail,

770 LIST_LOOP_2 and EXTERNAL_LIST_LOOP_2 are the standard, most-often used
771 macros. They take two arguments, an element variable ELT and the list
772 LIST. ELT is automatically declared, and set to each element in turn
775 LIST_LOOP_3 and EXTERNAL_LIST_LOOP_3 are the same, but they have a third
776 argument TAIL, another automatically-declared variable. At each iteration,
777 this one points to the cons cell for which ELT is the car.
779 EXTERNAL_LIST_LOOP_4 is like EXTERNAL_LIST_LOOP_3 but takes an additional
780 LEN argument, again automatically declared, which counts the number of
781 iterations gone by. It is 0 during the first iteration.
783 EXTERNAL_LIST_LOOP_4_NO_DECLARE is like EXTERNAL_LIST_LOOP_4 but none
784 of the variables are automatically declared, and so you need to declare
785 them yourself. (ELT and TAIL are Lisp_Objects, and LEN is an EMACS_INT.)

997 EXTERNAL_PROPERTY_LIST_LOOP_3 maps over an external list assumed to
998 be a property list, consisting of alternating pairs of keys
999 (typically symbols or keywords) and values. Each iteration
1000 processes one such pair out of LIST, assigning the two elements to
1001 KEY and VALUE respectively. Malformed lists and circularities are
1002 trapped as usual, and in addition, property lists with an odd number
1003 of elements also signal an error.
