defsystem

This macro creates a new system with name system-name and options taken from options, containing module-groups specified by modules. system-name must be a symbol (we recommend using a keyword) which will identify the system. options must be a (possibly empty) list of keyword/value pairs. modules is a list consisting of one or more short form module-specifications and/or long form module-specifications.

See also defsystem.htm for general information on the defsystem facility in Allegro CL and for a description of module specifications.

Keyword	value type	default value	Notes
`:pretty-name`	string	print-name of system-name symbol	This name will be used for printing.
`:default-module-class`	symbol identifying a class	`ds:lisp-module`	Predefined classes are: `ds:lisp-module`, `ds:text-module`, `ds:c-module`. Users may define additional classes, see defsystem.htm.
`:default-package`	package object or string or symbol naming a package	The value of `package`	Can be overridden for a module or module-group with the package option in the long module form. Also can be overridden during an operation with the package argument.
`:default-pathname`	pathname object or string or symbol naming pathname	default-pathname-defaults	This pathname will be merged with the filenames of the modules of the system in order to find files.
`:default-file-type`	string	depends on value of `:default-module-class` - see notes at right.	Specifies file type (extension) for source files for modules in system. If :default-module-class is ds:lisp-module, default is value of `source-file-types`; if ds:text-module, default is nil; if ds:c-module, default is "c".
`:property-list`	property list	`nil`	The value is added to the property list of the system.
