Swcase

Make-swcase

Basic constructor macro for swcase structures.

Syntax

(make-swcase [:value <value>] 
             [:body <body>])

This is the usual way to construct swcase structures. It simply conses together a structure with the specified fields.

This macro generates a new swcase structure from scratch. See also change-swcase, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-swcase

(defmacro make-swcase (&rest args)
  (std::make-aggregate 'swcase
                       args '((:value) (:body))
                       'make-swcase
                       nil))

Function: swcase

(defun swcase (value body)
  (declare (xargs :guard (and (literalp value) (blockp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'swcase))
    (declare (ignorable __function__))
    (b* ((value (mbe :logic (literal-fix value)
                     :exec value))
         (body (mbe :logic (block-fix body)
                    :exec body)))
      (cons :swcase (list (cons 'value value)
                          (cons 'body body))))))
