Headers with centered content

ConTeXt offers the possibility to have mirrored headers (for odd and even pages); content can be in two parts, at the inner and outer margin of each page. But how do you get a header that will have one part of its content centered and one part in the outer margin? (This is a common setup for books: chapter title centered, page number in outer margin.) Hans posted this solution to the list:

\setuppagenumbering[alternative=doublesided]

\setupheadertexts[]
\setupheadertexts[\setups{text a}][][][\setups{text b}]

\startsetups[text a]
  \rlap{\pagenumber}
  \hfill
  \getmarking[chapter]
  \hfill
  \llap{whatever}
\stopsetups

\startsetups[text b]
  \rlap{whatever}
  \hfill
  \getmarking[section]
  \hfill
  \llap{\pagenumber}
\stopsetups

The use of the TeX macros rlap and llap allows centering of content. Note that \pagenumber gets you the number prior to conversion; if you're using \setupuserpagenumber[numberconversion=...] then you'll want to use \userpagenumber instead.

Using capitals

In the previous example, the chapter title and the section title were fetched with the macro \getmarking which wraps around \fetchmark. However, in case you need a raw version of the mark, say for instance to put it uppercase, you may use this setup instead:


\startsetups[text a]
  \rlap{\pagenumber}
  \hfill
  \expanded{\uppercase{\fetchmark[chapter][first]}}
  \hfill
  \llap{whatever}
\stopsetups

\startsetups[text b]
  \rlap{whatever}
  \hfill
  \expanded{\uppercase{\fetchmark[section][first]}}
  \hfill
  \llap{\pagenumber}
\stopsetups


You can replace \uppercase by \WORD and so on.

Marginal headings and centered headings

The following file gives a way to achieve marginal and centered headings for doublesided documents. Experiment to achieve other effects!

\setuppapersize [A5][A4]

\newdimen\Margin
\Margin=3cm

\newdimen\MarginRaise
\MarginRaise=56ex

\setuplayout[width=middle,
             height=middle,
             footer=3\bodyfontsize,
             header=\bodyfontsize,
             headerdistance=\bodyfontsize,
             bottom=3\bodyfontsize,
             location={middle,doublesided},
             margin=\Margin,
             marking=on]

\setuppagenumbering[alternative=doublesided,
                    location={footer,middle}]

Skipping headers or footers

You can suppress or bypass a header or footer on a chapter page like this:

\setuphead[chapter][header=high,footer=none] % with header=high the text area of the page will extend up into the space where the header normaly sits
% or:
\setuphead[chapter][header=empty,footer=none] % header=empty leaves the header area intact, but does not fill it with any text

The options for 'header=' and 'footer=' are none,empty,high,nomarking.

Adding a line below the header

There are two ways to achieve this:

\setupbackgrounds[header][text][bottomframe=on]

The above method will require the header=high option if you want to skip the line on pages where a chapter begins (with header=empty the line will still be there but with no text). The second method allows skipping the header (including the line) with both the header={empty|high} option.

\setupheader[text][after={\blackrule[width=\textwidth,height=\linewidth,depth=0pt]}]
