GBBopen 1.5 Reference -- with-saving/sending-block

with-saving/sending-block

with-saving/sending-block (stream &key package read-default-float-format value) form* => result* [Macro]

Purpose
Bind printer and GBBopen save/send control variables) to values that produce standard GBBopen save/send-object behavior when evaluating forms.

Package :gbbopen-tools

Module :gbbopen-tools

Arguments and values

stream		A stream
package		A package designator indicating the package to be used when saving/sending and when loading/receiving (default is `:common-lisp`)
read-default-float-format		One of the atomic type specifiers `short-float`, `single-float`, `double-float`, or `long-float` (default is `single-float`)
value		An object to be saved/sent and bound to *block-saved/sent-value* when loading/receiving with with-reading-saved/sent-objects-block (default is `nil`)
forms		An implicit progn of forms to be evaluated
results		The values returned by evaluating the last `form`

Returns
The values returned by evaluating the last form.

Description
Within the dynamic extent of the body of forms, all Common Lisp printer control variables (including any implementation-defined ones) and GBBopen save/send control variables are bound to values that produce standard GBBopen save/send-object behavior. The function save-blackboard-repository establishes a with-saving/sending-block when saving the blackboard repository, and this macro can be used in constructing specialized saving/sending operations.
