record-source-file

Arguments: fspec &key type

This function is used to record the location of built-in and user defined objects in source files.

The built-in types and the forms that use them are:

For example, putting the following form into a file, compile and loading it: (defun foo (x) ...) will cause foo to be recorded as an :operator in the file in which it was defined.

Redefinition warnings occur when a file is be loaded and it defines an object of an already existing source file recording type. Objects of different types, say an :operator and :type, do not cause redefinition warnings.

Users can extend this facility to understand objects they define. The most usual case is a macro that defines a high-level object, such as:

(defmacro def-frob (name fram)
  `(progn
     (record-source-file ',name :type :frob)
     (def-frob-1 ',name ,fram)))

Then, if the following form is put into /a/b/foo.cl:

(def-frob akbar 'fez)

and is then compiled and loaded, (source-file 'akbar :frob) will return a pathname pointing to /a/b/foo.cl.
