Function unuse-package

Syntax:

unuse-package packages-to-unuse &optional package t

Arguments and Values:

packages-to-unuse—a designator for a list of package designators.

Issue PACKAGE-FUNCTION-CONSISTENCY is silent on whether a "package designator" is really the right thing here, but KAB, Sandra, and KMP agree that this is what was probably intended.package—a package designator. The default is the current package.

Description:

11.2.0 37unuse-package causes package to cease inheriting all the external symbols of packages-to-unuse; unuse-package undoes the effects of use-package. The packages-to-unuse are removed from the use list of package.

Sandra: Redundant. The \term{external symbols} of the \param{packages-to-unuse} are no longer inherited. However,Any symbols that have been imported into package continue to be present in package.

Examples:

 (in-package "COMMON-LISP-USER") → #<PACKAGE "COMMON-LISP-USER">
 (export (intern "SHOES" (make-package 'temp)) 'temp) → T
 (find-symbol "SHOES") → NIL, NIL
 (use-package 'temp) → T
 (find-symbol "SHOES") → SHOES, :INHERITED
 (find (find-package 'temp) (package-use-list 'common-lisp-user)) → #<PACKAGE "TEMP">
 (unuse-package 'temp) → T
 (find-symbol "SHOES") → NIL, NIL
