Matchresult

Make-matchresult

Basic constructor macro for matchresult structures.

Syntax

(make-matchresult [:loc <loc>] 
                  [:len <len>] 
                  [:str <str>] 
                  [:backrefs <backrefs>])

This is the usual way to construct matchresult structures. It simply conses together a structure with the specified fields.

This macro generates a new matchresult structure from scratch. See also change-matchresult, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by defprod.

Macro: make-matchresult

(defmacro make-matchresult (&rest args)
  (std::make-aggregate 'matchresult
                       args '((:loc) (:len) (:str) (:backrefs))
                       'make-matchresult
                       nil))

Function: matchresult

(defun matchresult (loc len str backrefs)
  (declare (xargs :guard (and (maybe-natp loc)
                              (natp len)
                              (stringp str)
                              (backref-alist-p backrefs))))
  (declare (xargs :guard t))
  (let ((__function__ 'matchresult))
    (declare (ignorable __function__))
    (b* ((loc (mbe :logic (maybe-natp-fix loc)
                   :exec loc))
         (len (mbe :logic (nfix len) :exec len))
         (str (mbe :logic (acl2::str-fix str)
                   :exec str))
         (backrefs (mbe :logic (backref-alist-fix backrefs)
                        :exec backrefs)))
      (list loc len str backrefs))))
