Tokenlist-p

(tokenlist-p x) recognizes lists where every element satisfies token-p.

Signature

(tokenlist-p x) → std::bool

This is an ordinary deflist. It is "loose" in that it does not care whether x is nil-terminated.

Definitions and Theorems

Function: tokenlist-p

(defun tokenlist-p (x)
       (declare (xargs :guard t))
       (let ((__function__ 'tokenlist-p))
            (declare (ignorable __function__))
            (if (consp x)
                (and (token-p (car x))
                     (tokenlist-p (cdr x)))
                t)))
