Locator

Make-locator

Basic constructor macro for locator structures.

Syntax

(make-locator [:program <program>] 
              [:name <name>])

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

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

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-locator

(defmacro make-locator (&rest args)
  (std::make-aggregate 'locator
                       args '((:program) (:name))
                       'make-locator
                       nil))

Function: locator

(defun locator (program name)
  (declare (xargs :guard (and (programidp program)
                              (identifierp name))))
  (declare (xargs :guard t))
  (let ((__function__ 'locator))
    (declare (ignorable __function__))
    (b* ((program (mbe :logic (programid-fix program)
                       :exec program))
         (name (mbe :logic (identifier-fix name)
                    :exec name)))
      (cons :locator (list (cons 'program program)
                           (cons 'name name))))))
