Dear list,
I have the following sample:
\starttext
\chapter{Chapter}
.\doifemptyelse{\getmarking[section][current]}
{\getmarking[chapter][current]}
{\getmarking[section][current]}.
\section{Section}
.\doifemptyelse{\getmarking[section][current]}
{\getmarking[chapter][current]}
{\getmarking[section][current]}.
\stoptext
I must be missing something extremely basic, because I think that the
first condiitonal occurs when \getmarking[section][current] is empty
(dots have nothing in between).
How can I make the first conditional work?
Many thanks for your help,
Pablo

You can’t, markings are only reliable when you use them in the header of footer of the page.
To access the values of a heading you can use the \structurevariable and \namedstructurevariable commands.
\starttext
\chapter{Chapter}
A: \doifsomethingelse{\namedstructurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\section{Section}
A: \doifsomethingelse{\structurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\subsection{Subsection}
A: \doifsomethingelse{\structurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}
B: \structurevariable{title}
\stoptext
Wolfgang

Many thanks for your reply, Wolfgang.
My question was about headers, but I didn’t mention it to make a shorter
sample.
The code now is the following:
\setupheadertexts[\hfill\namedstructurevariable{chapter}{title}\hfill]
[] []
[\hfill\doifsomethingelse{\namedstructurevariable{section}{title}}
{\namedstructurevariable{section}{title}}
{\namedstructurevariable{chapter}{title}}\hfill]
Only a minor detail: is there a more proper way to center both headings?
Many thanks for your help,
Pablo

In this case this was a important part for the solution because it makes a difference
when you use \getmarking in \setupheadertexts or in the text.

You can use the simple version of \setupheadertexts and use \doifoddpageelse
to check whether you’re on a left or right page. When you make a test for content
of a \getmarking command you have to use \doiftext because the \doifempty etc.
checks don’t work in this case.
\startsetups[header]
\doifoddpageelse
{
\getmarking[chapter]
}
{
\doiftextelse
{
\getmarking[section]
}
{
\getmarking[section]
}
{
\getmarking[chapter]
}
}
\stopsetups
\setupheadertexts[\directsetup{header}]
\setupfootertexts[pagenumber]
\starttext
\chapter{Chapter A}
\page
\chapter{Chapter B}
\page
\dorecurse{5}
{\chapter{Chapter #1}
\dorecurse{10}
{\section{Section #1.##1}
\dorecurse{3}{\input knuth\par}}}
\stoptext
Wolfgang

Many thanks for your reply, Wolfgang.
This was exactly what I needed. I must admit that I didn’t understood
what the simple version of \setupheadertexts was about. And \doiftext
(as well as \doifsomething) were totally unknown to me.
Many thanks again for your help,
Pablo
