The slightly interesting thing here is that we have an opportunity here to make this slightly faster -- since we have an upper length bound here, we can eschew the tortoise/hare FOR_EACH_TAIL bit and just follow CDRs, which would be faster. Of course, if you give it a circular list, then it'll always return Qnil, and if you give it (expt most-positive-fixnum most-positive-fixnum) on a circular list, it'll take a while... diff --git a/src/fns.c b/src/fns.c index 646c3ed083..2234818e8e 100644 --- a/src/fns.c +++ b/src/fns.c @@ -145,6 +145,29 @@ DEFUN ("safe-length", Fsafe_length, Ssafe_length, 1, 1, 0, return make_fixnum (len); } +DEFUN ("length<", Flength_less, Slength_less, 2, 2, 0, + doc: /* Return non-nil if SEQUENCE is shorter than LENGTH. +See `length' for allowed values of SEQUENCE. */) + (Lisp_Object sequence, Lisp_Object length) +{ + CHECK_INTEGER (length); + EMACS_INT len = XFIXNUM (length); + + if (CONSP (sequence)) + { + intptr_t i = 0; + FOR_EACH_TAIL (sequence) + { + i++; + if (i >= len) + return Qnil; + } + return Qt; + } + else + return XFIXNUM (Flength (sequence)) < len?
