  ANSI Common Lisp   11 Packages   11.2 Dictionary of Packages

11.2.12 make-package Function

make-package package-name &key nicknames use    package

Arguments and Values:
package-name - a string designator.

nicknames - a list of string designators. The default is the empty list.

use - a list of package designators. The default is implementation-defined.

package - a package.

Creates a new package with the name package-name.

Nicknames are additional names which may be used to refer to the new package.

use specifies zero or more packages the external symbols of which are to be inherited by the new package. See the function use-package.

 (make-package 'temporary :nicknames '("TEMP" "temp"))  #<PACKAGE "TEMPORARY">
 (make-package "OWNER" :use '("temp"))  #<PACKAGE "OWNER">
 (package-used-by-list 'temp)  (#<PACKAGE "OWNER">)
 (package-use-list 'owner)  (#<PACKAGE "TEMPORARY">)

Affected By:
The existence of other packages in the system.

Exceptional Situations:
The consequences are unspecified if packages denoted by use do not exist.

A correctable error is signaled if the package-name or any of the nicknames is already the name or nickname of an existing package.

See Also:
defpackage, use-package

In situations where the packages to be used contain symbols which would conflict, it is necessary to first create the package with :use '(), then to use shadow or shadowing-import to address the conflicts, and then after that to use use-package once the conflicts have been addressed.

When packages are being created as part of the static definition of a program rather than dynamically by the program, it is generally considered more stylistically appropriate to use defpackage rather than make-package.

Allegro CL Implementation Details:
Allegro CL has added some keyword arguments. See Extensions to cl:make-package in implementation.htm. Note that link is to the documentation for the current Allegro CL version. Replace /current/ in the URL with the Allegro CL version number to see similar documentation in earlier releases.
