I don't know, but with \dorecurse{2}{\input tufte \par} \page \section{Two} things go better. -- luigi

Of course, manually tweaking helps. Only, one needs to see that here is a page where tweaking is needed! And this is the problem: The head says "1.2 one", but it should be "1.1 one"! First I trusted the automated head entries, then I realized it can be wrong and now I skim typeset books before sending them to printer. But when skimming a book it is quite likely to not-see the wrong "1" when seeing the correct "one"! Is there no way to automatically get the correct number information "1.1" that is corresponding to the correct text entry "one"?? "\getmarking[section]" provides the right information, "\headnumber[section]" is too far in border cases ... Isn't there a command that gets the number that belongs to the text of "\getmarking[section]" Steffen Am 10.03.2011 um 15:16 schrieb Willi Egger:

I agree with Luigi, after using different length and \page I was able to produce correct output. According to me your example is probably a border case.

things go better.

\getmarking[sectionnumber] % partnumber, chapternumber etc.

Sure, but why does TeX write "1.2 one"? The second part "one" is correct ... Why can't both parts be synchronized (correctly of course!)??

It’s because \headnumber is macro expansion which happens when TeX collects material for the page and \getmarking use TeX’s mark mechanism which is meant for elements which are added after the page is finished. Here is a example which shows a problem with expansion: \setuplayout[lines=10] \def\foo{foo} \appendtoks\gdef\foo{bar}\to\everyaftershipout \starttext \dorecurse{20}{\foo\par} \stoptext What you can do is to create a new mark with \definemarking where you set \headnumber and which you then use in the header.
