header/footer suppression

header/footer suppression

[Guy Worthington]

I can't get both a blank page inserted whenever a chapter finishes on
an odd page and also suppress my header on the first page of a
chapter.  Here's my minimal example:

-----

% output=pdftex
\starttext
\setuphead
  [chapter]
  [before={\page\ifodd\realpageno\else\page[empty]\fi\page[right]},
   header=empty]
\setupheadertexts
  [chapter]
\setuppagenumbering[alternative=doublesided,
                    option=doublesided]

\chapter {test} \dorecurse{10}{\input tufte }
\chapter {test} \dorecurse{10}{\input tufte }
\chapter {test} \dorecurse{10}{\input tufte }
\stoptext

perhaps this hack will help you?

Thanks Patrick, the next specification is that I have a footer.

-----
% output=pdftex
\definetext[chapter][footer][pagenumber] % page on which chapters begin
\setuphead
  [chapter]
  [page=right,
   header=empty,
   footer=chapter,
%   before={\page\ifodd\realpageno\else\page[empty]\fi\page[right]},
]
\setupheadertexts
  [chapter]
\setuppagenumbering[alternative=doublesided]

\starttext
\chapter {test} \dorecurse{10}{\input tufte }
\chapter {test} \dorecurse{10}{\input tufte }
\chapter {test} \dorecurse{10}{\input tufte }
\stoptext

is used to produce an even number of pages, so if you count ever page
in the book then the number of recto and verso pages are exactly
equal.

Sorry, but I don't get what you are trying to achieve (it is too early
for me, I guess). One thing that is clear: You want to start chapters
on an odd (right) page. On this page, what should be in the
header/footer? On the page before that, if it is empty, what do you
want there? And how should the header and footer look like on a
regular page?

this has no effect here (pagenumber is in the center of the
header). Try \setuppagenumbering[location=].

You've a good success rate -- first time you haven't read my mind.

Yep.

> On this page, what should be in the header/footer?

The page number should be centered in the footer.  The header is
empty.

> On the page before that, if it is empty, what do you want there?

Nothing. A completely blank page.

> And how should the header and footer look like on a regular page?

The footer is empty.  The header contains the page number next to the
outside margin.

Patrick, I'm posting my environment (on the offchance it might help

If you compile this, you'll notice that on the very first page I have
a header, I don't want the header, I want a footer with the page number.

Your wish is beyond my ConTeXt knowlege. Ask me again in a year :)

One problem is that with \setuphead[chapter][page=yes] the chapter can
start on an even page. On that page the setup from
\definetext[chapter]... is taken. Then, with my previously suggested
hack, ConTeXt goes to the next page. There you have to setup your
header/footer manually, but reset it again on next page.

With [page=right] ConTeXt has no way(?) of knowing that it should leave
the even page blank.

I suggest that "we" add a new keyword to setuphead (no idea what to name
it, perhaps skippages=blank) and Hans does some miracle-coding in
\dohandelpaginaafB (or wherever). 

And/or:  we could use a keyword in setupheader,setupfooter,...:
state=once. This way we could setup a headertext and don't have to
worry about it on next page. 

Patrick



But there is probably a) a switch already in ConTeXt, that I haven't
seen or b) Hans has just needed such code, so it is already in the
pre-beta ...

\doifoddpageelse{...}{...}

this one compensates for shifted pages and is fully expandable

There is a cleaner solution:

\unprotect

% more tolerancy needed

\def\dohandelpaginaafB#1%
   {\doifvaluesomething{\??ko#1\c!pagina}
      {\def\resetcurrentsectionmarks% toegevoegd, zie \pagina
         {\resetsectionmarks{\previoussection\@@sectie}}%
       \pagina[\getvalue{\??ko#1\c!pagina}]%
       \dohandelpaginaafBB{#1}\v!hoofd\c!hoofd
       \dohandelpaginaafBB{#1}\v!tekst\c!tekst
       \dohandelpaginaafBB{#1}\v!voet \c!voet}}

% we install a few page handler keys

\installpagebreakhandler \v!hoofd
   {\doifnotvalue{\??tk\v!hoofd\c!status}\v!stop
      {\setupheader[\c!status=\v!leeg]}}

\installpagebreakhandler \v!voet
   {\doifnotvalue{\??tk\v!voet\c!status}\v!stop
      {\setupfooter[\c!status=\v!leeg]}}

\protect

now we can define a new page break:

\definepagebreak
   [chapter]
   [yes,header,right]

look how much cleaner this looks:

\setuphead
   [chapter]
   [page=chapter,
    header=empty,
    footer=chapter]

this is pretty cool! Is it documented somewhere? (besides \def\...)

since the header key is defined here, it's not yet documented -)

\definepagebreak is already there foe some time and not documented 
(\definepagabreak, \defineblank, \definecolumnbreal ...)

This permits things like:

first version of doc:

\definepagebreak[version1] [yes]     .... \page[version1] -> pagebreak

second version of doc:

\definepagebreak[version1][]         .... \page[version1] -> ignored
\define[agebreak[version2][yes]      .... \page[version2] -> pagebreak

header/footer suppression

[Pierre Goossens]

Hello everyone,

I am writing a document which I would like to print double-sided. 

I use the dutch commands:

\stelhoofdtekstenin[paragraaf][hoofdstuk]
\stelnummeringin[plaats={voet,kantlijn},variant=dubbelzijdig]

or in english:
\setupheadertexts[section][chapter]
\setuppagenumbering[location={footer,marginedge},alternative=doublesided]

When a chapter ends on an odd page, I would like the next even page to be
completely blank. Sounds simple enough, but how do I achieve this? I am no
TeXnician, so I ask you if this is possible with a standard command. If
anyone knows a solution I am much obliged.

Greetings,

Pierre Goossens

By default a chapter starts on an odd page. 

\setuphead[chapter[page=right] 
\stelkopin[hoofdstuk][pagina=rechts]

other options are: left|links viertal|quadruple or any page option. 

Does left/right solve your problem or do you need something else?

I would not dream to ask a question when the answer can be found in one of
those nice manuals like cont-eni or cont-nli! :-)

>>When a chapter ends on an odd page, 
                 ^^^^ 
Let me clarify this. By default a chapter starts on an odd page, for
instance page number 7. One can imagine that the chapter *ends* for
instance on page number 11. But now my problem: the following even page 12
still displays the chapter title in the headertext but I want this to be
empty! So:

>>I would like the next even page to be completely blank. 

Actually I am not that bothered by the pagenumbers but I would like to know
who to turn those off in the above example.

>other options are: viertal|quadruple or any page option. 
Nice ways to save paper, but no.

>Does left/right solve your problem or do you need something else? 
Something else, please, thank you.
