Logical-name-listp

Recognize true lists of logical names.

Signature

(logical-name-listp names wrld) → yes/no

Arguments

wrld — Guard (plist-worldp wrld).

Returns

yes/no — Type (booleanp yes/no).

See logical-namep in the ACL2 source code.

While logical-namep is not boolean-valued, this function always returns a boolean.

We cannot use std::deflist to define this function because that macro attempts to prove that logical-namep is boolean-valued.

Definitions and Theorems

Function: logical-name-listp

(defun logical-name-listp (names wrld)
  (declare (xargs :guard (plist-worldp wrld)))
  (let ((__function__ 'logical-name-listp))
    (declare (ignorable __function__))
    (cond ((atom names) (null names))
          (t (and (logical-namep (car names) wrld)
                  (logical-name-listp (cdr names)
                                      wrld))))))

Theorem: booleanp-of-logical-name-listp

(defthm booleanp-of-logical-name-listp
  (b* ((yes/no (logical-name-listp names wrld)))
    (booleanp yes/no))
