Doublesided, with header text centered.

Doublesided, with header text centered.

[John R. Culleton]

Here is a common situation. I need a doublesided layout so I can
adjust the backspace. I want the header text on evens and odds
centered over the text block. To simplify the issue let's say 
I want "left" on the evens and "right" on the odds. If I specify 
(per the manual)
\setupheadertexts[text][left][right] 
then I get both words on both pages. 
If I use two extra sets of [] then I can get "left" on the left
and "right" on the right but I cannot get them centered.

I am missing something obvious I am sure. Anyone have a firm
grasp of the obvious? I don't.

If I understand you correctly, use \setupheadertexts[center]. If you 
want something in the left, center and right, then do

\setupheadertexts[left][right]
\setupheadertexts[center]

I misread your mail. How about something like this

\def\setupextendedheadertexts{%
   \dosixtupleempty\dosetupextendedheadertexts}

\def\dosetupextendedheadertexts[#1][#2][#3][#4][#5][#6]{
   \setupheadertexts[] %Empty the center headers
   \setupheadertexts
     %Odd page
     [{\rlap{#1}\hfill#2\hfill\llap{#3}}][]
     %Even page
     [][{\rlap{#4}\hfill#5\hfill\llap{#6}}]}

\setupextendedheadertexts[odd-left][odd-center][odd-right][even-left][even-center][even-right]

\starttext
\dorecurse{10}{This is a test \page}
\stoptext


This does not take care of "magic" texts like pagenumber, section, 
chapter. If you want that, you can try (careful with linebreaks)

\def\setupextendedheadertexts{%
   \dosixtupleempty\dosetupextendedheadertexts}

\def\dosetupextendedheadertexts[#1][#2][#3][#4][#5][#6]{
   \setupheadertexts[] %Empty the center headers
   \setupheadertexts
     %Odd page
[{\rlap{\domagic{#1}}\hfill\domagic{#2}\hfill\llap{\domagic{#3}}}][]
     %Even page
[][{\rlap{\domagic{#4}}\hfill\domagic{#5}\hfill\llap{\domagic{#6}}}]}

\unprotect
\def\domagic#1{%
   \convertargument#1\to\ascii
   \doifsomething\ascii{%
     \doifelsemarking\ascii
       {\getmarking[\ascii][\v!first]}
       {\ConvertConstantAfter\doifelse\v!pagenumber{#1}
         \@@plaatspaginanummer
         {\ConvertConstantAfter\doifelse\v!date{#1}
           {\currentdate}
           {#1{}{}{}}}}}}
\protect

\setupextendedheadertexts[date][chapter][pagenumber][pagenumber][section][Whatever]

\starttext
\dorecurse{4}{

   \input tufte \endgraf
   \input tufte \endgraf
   \input tufte \endgraf

Very impressive, but surely there is a simpler solution! I just
want one header on the left hand page, a different one on the
right, and both of them centered on their respective pages.

\def\MyHeader{
   \doifoddpageelse{Odd Header}
   {Even Header}}

\setupheadertexts[\MyHeader]

If you want you can extend it to recognize keywords like date, 
pagenumber, section etc.

Re: Doublesided, with header text centered.

[Willi Egger]

Hi John,

Humble, if I understand your question correctly then for me the 
following works:

\setupheadertexts[\hfill 
{\getmarking[section][last]}\hfill][pagenumber][pagenumber][\hfill Even 
page text\hfill]
\setuppagenumbering[location=, alternative=doublesided]

\starttext
\dorecurse{20}{\input knuth\blank[1cm]}
\stoptext

I have to admit that there might something be broken. If I compile the 
sample I get the wrong sectionnumber in the header. i.e. the section 
number of the first section on the next page is given. If I use [first] 
instead of last, the first sectionnumber should be given, but in this 
sample still the section number of the first section of the following 
page is given.
Hans may be you could have a look into this matter? - Or am I doing 
wrong things?


Cheers

Willi

Yes, I can do the above. Unfortunately the keywords like chapter
lose their special meaning when enclosed in any way. For example
\setupheadertexts
[chapter]
[][]
[\hfil\hbox to 20em{\stretched{\tfb\sc
Independent{}Publishing}}\hfil]

...works, but as soon as I place any command ahead of the keyword
chapter it just becomes the word "chapter". for example this
doesn't work:

\setupheadertexts
[\hfil chapter\hfil]
[][]
[\hfil\hbox to 20em{\stretched{\tfb\sc
Independent{}Publishing}}\hfil]


And if I put commands in the \setupheader statement then this
works:

\setupheader[text][before={\tfb\sc\hskip 1in}}] 
but this has no effect:
\setupheader[text][before={\tfb\sc\hfil},after={\hfil}] 

I can of course roll my own as you suggest above. But if I want
chapter as a variable then I will have to encapsulate my \chapter
command thus:

\def\Chapter#1{\global\def\mychaptername{#1}\chapter{#1}}

...and use \mychaptername in my home grown header routine. 

In fact I have done just that today:
\def\mychapter{}
\def\Chapter#1{\global\def\mychapter{\tfb\sc\hfil#1\hfil}\chapter#1}

I can probably even get stretching in there if I work at it. 


I don't mind doing this kind of plain tex manipulation but it
still seems to me that Context should handle it somehow.

You can use the \domagic macro from my previous email to handle 
chapter, date and pagenumber.

If you just want chapter markings, use \getmarking[chapter].

It seems that something is broken. Even this simple example gives 
wrong headers

\setupheadertexts[section]
\starttext
  \dorecurse{20}{\section{Test \recurselevel}\input knuth\endgraf}
\stoptext
