Macro

Summary

Returns the source location.

Package

dspec

Signature

location => location

Values

location

A pathname or a keyword.

Description

The macro location returns a location suitable for passing to record-definition. This is usually done via a separate defining function. You will need to use location only if you create your own ways of making definitions (and not if your definers call only system-provided definers).

Example

(defmacro define-wibble (x y) 

  `(dspec:def (define-wibble ,x) 

     (set-wibble-definition ',x ',y (dspec:location))))

(defun set-wibble-definition (x y loc) 

  (when (record-definition `(define-wibble ,x) loc)

    ;; defining code here

    ))
