Function

Make-function

Basic constructor macro for function structures.

Syntax

(make-function [:name <name>] 
               [:params <params>] 
               [:body <body>])

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

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

Definition

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

Macro: make-function

(defmacro make-function (&rest args)
  (std::make-aggregate 'function
                       args '((:name) (:params) (:body))
                       'make-function
                       nil))

(defun function (name params body)
  (declare (xargs :guard (and (symbol-valuep name)
                              (symbol-value-listp params)
                              (ttermp body))))
  (declare (xargs :guard t))
  (let ((__function__ 'function))
    (declare (ignorable __function__))
    (b* ((name (mbe :logic (symbol-value-fix name)
                    :exec name))
         (params (mbe :logic (symbol-value-list-fix params)
                      :exec params))
         (body (mbe :logic (tterm-fix body)
                    :exec body)))
      (list name params body))))
