Binds a variable to either t
or nil
, and executes a body of code to print a page only if the variable is t
.
The with-page
macro binds var to t
if a page is to be printed, or nil
if it is to be skipped. The body is executed once, and is expected to draw the document only if var is t
. Each call to with-page
contributes a new page to the document.
