header entries semi-wrong

header entries semi-wrong

[Steffen Wolfrum]

Hi,

please run the minimal example attached:

--on page 1 there is 
section "1.1 one" and you get the header entry "1.1 one"
- on page 3 there is still 
section "1.1 one" and you get the header entry "1.2 one" (<- ?!)
- on page 5 there is 
section "1.2 two" and you get the header entry "1.2 two"

you see the problem? the "getmarking" behaves correctly (one/one/two)
while the "headnumber" is confused (1.1/1.2/1.2))!


Is this a bug or am I doing something wrong?

Steffen

Could some maybe please have look at my test file (see original post):
Is this "asynchronous"head  a bug or am I simply doing something wrong??

I don't know, but with

\dorecurse{2}{\input tufte \par}
\page
\section{Two}

things go better.

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.

TeX reads always more text than it needs for a page and in your example
the “Section 1.2” was seen by TeX when it was building page 3 although
it didn’t fit and was postponed till page 4.

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!)??

Re: header entries semi-wrong

[Steffen Wolfrum]

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]"

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.

Yes!

"\getmarking[sectionnumber]"

This one I have been seeking for so long now.
