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
