Binds a variable to either t
or nil
, and executes a body of code to print a page only if the variable is t
.
capi
with-page (printp) &body body
printp⇩ |
A symbol (not evaluated). |
body⇩ |
Lisp forms. |
The macro with-page
binds printp to t
if a page is to be printed, or nil
if it is to be skipped. The forms in body are evaluated once as in implicit progn, and are expected to draw the document only if printp is t
.
Each call to with-page
contributes a new page to the document.
with-page
must be called within the dynamic context of with-print-job.
with-page
does not work on Cocoa.nil
when only part of the document is printed, for example when the user specifies that she wants only odd pages. When printp is nil
, the code in body needs to ensure that the next call to with-page
prints the right page.
