Ienv

Make-ienv

Basic constructor macro for ienv structures.

Syntax

(make-ienv [:uchar-format <uchar-format>] 
           [:schar-format <schar-format>])

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

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

Definition

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

Macro: make-ienv

(defmacro make-ienv (&rest args)
  (std::make-aggregate 'ienv
                       args '((:uchar-format) (:schar-format))
                       'make-ienv
                       nil))

Function: ienv

(defun ienv (uchar-format schar-format)
  (declare (xargs :guard (and (uchar-formatp uchar-format)
                              (schar-formatp schar-format))))
  (declare (xargs :guard t))
  (let ((__function__ 'ienv))
    (declare (ignorable __function__))
    (b* ((uchar-format (mbe :logic (uchar-format-fix uchar-format)
                            :exec uchar-format))
         (schar-format (mbe :logic (schar-format-fix schar-format)
                            :exec schar-format)))
      (cons :ienv (list (cons 'uchar-format uchar-format)
                        (cons 'schar-format schar-format))))))
