defpackage

Macro
Summary

Remains as defined in Common Lisp, but see *handle-existing-defpackage* for an HCL extension.

Package

common-lisp

Signature

defpackage defined-package-name option &key add-use-defaults => package

Arguments

defined-package-name

A string.

option

Keyword options.

add-use-defaults

A keyword

Values

package

A package.

Description

The macro defpackage is as defined in the ANSI standard, with the inclusion of the :add-use-defaults keyword. However, the standard explicitly declines to define what defpackage does if defined-package-name already exists and is in a state that differs from that described by the defpackage form.

Therefore an extension has been written that allows you to select between alternative behaviors. See *handle-existing-defpackage* for full details.

If add-use-defaults is specified with the argument t , the following packages are included in the defined package:

common-lisp

lispworks

harlequin-common-lisp
