So I tried to use this code a while back, filling in the ... as best I
could and didn't have much success at all. Before I go back to banging
my head against it, does anyone have an example of extremely simple
multi-page layout--I'm thinking of something along the lines of, I
have a string containing more text than will fit on a page; what's the
simplest way to get it turned into a multi-page PDF. No fancy
formatting required (or even desired at this point), just text broken
up into pages.

-Peter

P.S. Marc, I know you'd rather code than write docs but a set of
graduated cl-typesetting examples sort of like the ones in cl-pdf
would be a useful starting point for folks like me who like to learn
by grabbing something that works and try tweaking it in various ways.
The current cl-typesetting example, though an impressive demo, has a
bit much going on to be used in that way.

Here it is. I will add it to test.lisp.

(defun muli-page-hello (&optional (file #P"/tmp/hello.pdf"))
  (pdf:with-document ()
    (let ((content
    (compile-text ()
  (vspace 100)
  (paragraph (:h-align :centered :font "Helvetica-Bold" :font-size 50 :color

I don't have other examples. I use cl-typesetting in production applications
but the documents generated are embedded in these apps. I can't easily
extract them, and they would be mostly boring ;-) Nothing fancy.

So let's make a call for examples. If anybody has some examples to share
please post them to this list.

Cool. Thanks. That got me going. One oddity I noticed, at least when
viewing these docs with xpdf on GNU/Linux: if a paragraph gets broken
across a page, the text on the second page isn't colored. Any idea
what's up with that?

<time passes>

On a probably related note, check out my first crack at typesetting my
book with cl-typesetting.

  <http://www.gigamonkeys.com/book/chap1.pdf>

Notice how the beginning of each page loses it's formatting. The code
that generates this is at:

  <http://www.gigamonkeys.com/book/my-typeset.lisp>

The problem seems to be related to the way I'm adding the header in
draw-page. Poking around a bit I came up with theory that the
make-filled-vbox function is grabbing boxes from the main contents but
if the styles switch in the middle of a paragraph (as they do here
because of the header) they don't get put back when the lines
containing the rest of the paragraph are emitted. Of course that could
be totally wrong--just a guess really.

Anyway, if there's some better way to add a header, please let me
know.

Yes it's a bug ;-)
At the end of a draw box, the graphic state should be saved and restored for
the next draw box.

Great! A Lisp book in Lisp following the good old meta stuff tradition. :)

I will try to find some time to correct this. It should work.

Here's what I hacked up. Seems to fix my problem but I don't know if
it's The Right Thing.

Hmmm. I could of sworn this was working. But now it's not. (Or there's
something else wrong that manifests in the same way.)

Okay, looks like something else that manifests in the same way. With
my fix in 3/4 pages are formatted properly. One page, however, still
has the old problem--the remainder of a paragraph that crosses a page
boundary loses it's formatting. I have no theories unless you are
doing something about widow-and-orphans because the remainder happens
to be two lines.

More hacking has revealed that sometimes there are styles with NIL
fonts which tends to screw things up. I'm not sure where they come
from. But this patch at least makes my stuff work again. (To replace
the previous patch.)

Is there any way to output m- and n-dashes in cl-typesetting?

A user-drawn  box would be the easiest way IMO. Like the one where I draw a
pie chart in the example.

[Sorry for the late reply. I have to finish and install a new release of one
of my Lisp applications Wednesday. And Wednesday is in 25 minutes... ;-) I
will look at your patch and reply in more details tomorrow.]

Marc, did you have any thoughts on this?

Hi Peter,

 You should be able to use the raw character code for emdash and
 endash, which is 227 and 226 respectively in the WIN encoding (which
 seems to work across platforms).

 All the character encoding information is in Appendix D of Adobe's
 PDF spec (check http://partners.adobe.com/asn/tech/pdf/specifications.jsp).

 In cl-pdf you can just insert the raw escaped character code
 (e.g. "\\227") in a draw-text -- from the-typesetting layer I think
 you have to use something like cl-interpol to embed the escaped
 character in a string.

Yup. That seems to do the trick. Thanks. I'm curious how the encoding
gets specified in the document. But for now I'm good.

You should look at encoding.lisp and search for "endash" and "emdash" i the
encoding you use.
You can also make your own encoding by putting the "endash" and "emdash" in
place of characters you don't use.

I've added a *default-encoding* special variable to cl-pdf to specify a
default encoding for the fonts.
(it's on the repository)
