Hi Jim,
You are not doing anything wrong. The example on the wiki appears to be
obsolete (If you have a look through the mailing list archives, you’ll
see that Aditya notes that this command is obsolete...).
|\nomarking{...}| belonged to an older interface. This was already
discussed on the list in 2013, when Aditya explained that |\nomarking|
and |\nolist| were no longer needed: the structured sectioning interface
now lets us specify |title|, |marking|, |list|, and |bookmark| separately.
So the current equivalent would be something like:
\setupheadertexts[chapter]
\starttext
\startchapter
[title={This title is long enough to cause problems in the headers and
footers},
marking={This title is long ...}]
Here the whole title is used in the document, while the shorter
`marking` is used for the header.
\stopchapter
\stoptext
The same issue actually came up again on the mailing list in March 2025,
when |\nomarking| was found not to work with current ConTeXt.
So I think this is a documentation problem rather than a problem with
your input. The |\nomarking| wiki page should probably be revised or
marked as obsolete (mais qui va faire ce job ?).
Best,
JP

Hello all,
The example in the wiki for nomarking is (when rounded out with \starttext
and \stoptext):
\starttext
\chapter{This title is long \nomarking{enough to cause problems in the headers
and footers}}
Here the whole title will be displayed as normal, but if the chapter title is
used as a header or footer it will be displayed as:
This title is long ...
\stoptext
Disappointingly, when I run this example, I get

You injected something that confused the parser, maybe by using some Lua call.
mtx-context | fatal error: return code: 1

If I remove \nomarking, the example successfully compiles.
Is someone able to tell me if I am doing something wrong, and, if so,
exactly what I need to do in order to get on the correct path?
Thanks.
Jim
