Description

dump-forms-to-file dumps specified forms to a fasl file. Use the Common Lisp functionsmake-load-form andmake-load-form-saving-slots to control the dumping of forms.

LispWorks uses the following naming conventions for fasl files, and it is recommended that you should use them too, to ensure correct operation ofload and so on.

Table 10.1 Naming conventions for fasl files
Machine Architecture	Fasl File Extension
68000	`.fasl`
DECstation	`.dfasl`
SPARC	`.wfasl`
MIPS	`.mfasl`
Clipper	`.cfasl`
386 UNIX	`.3fasl`
386 Windows	`.fsl`

You can find the fasl file extension appropriate for your machine by looking at the variablesystem:*binary-file-type*. The variablesystem::*binary-file-types* contains a list of all the file extensions currently recognized byload.

For an example, see below.

USER 1 > (in-package "CL-USER")
#<The CL-USER package, 592/879 internal, 148/224 external>
CL-USER 2 > (defclass my-class () ((a :initarg :a :accessor my-a)))
#<class MY-CLASS>
CL-USER 3 > (setq my-instance (make-instance 'my-class :a 23))
#<standard-instance MY-CLASS>
CL-USER 4 > (defmethod make-load-form ((self my-class))
 '(make-instance ',(class-name (class-of self))
               :a ',(my-a self)))
#<Method MAKE-LOAD-FORM NIL (MY-CLASS)>
CL-USER 5 > (hcl:dump-forms-to-file 
    #p"/usr/users/ca/eg.wfasl"
