Problem with understanding \doifemptyelse

Problem with understanding \doifemptyelse

[Gilles Pérez-Lambert]

Hello,

I'm trying to setup headers in such a manner that on the left pages I 
have the chapter title and on the right the section one; but if there's 
no section, I want the chapter one...

I tried:
%%%%%%%%
\setupheadertexts
[][{%
\inframed[align=middle,frame=off,bottomframe=on,width=\makeupwidth]%
{\itx\hfill%
\doifemptyelse{\getmarking[section]}%%% If section header is empty
{\getmarking[chapter]}% Take the chapter one
{\getmarking[section]}}% else we take the section header
}]
[{\inframed[align=middle,frame=off,bottomframe=on,width=\makeupwidth]{\itx\
getmarking[chapter]\hfill\null}}][]
%%%%%%%%

I know I must miss something: \getmarking[section] is surely not that 
empty when there's nothing but my TeX knowledge is not that deep.

Another little problem: how not to have the headers on the beginning 
page of a chapter; i tried many things but didn't find the right one.

Thanks,

Gilles.

you're right, since \getmarking is doing a couple of things, it's never 
empty (for instance there is the test macro in there), instead use the low 
level fetcher:

\fetchmark[chapter][first]

(in supp-box (texexec --modu --pdf supp-box) you will find macros like 
\doifcontent that you can also use for such purposes)

Is there any special setup or location that I need to run that command
from?  I tried, because this is an issue that I will soon be looking at,
and got the following result:

] cd ~/tmp/tex
] texexec --modu --pdf supp-box

 TeXExec 2.7 - ConTeXt / PRAGMA ADE 1997-2001

        total run time : 0 seconds

Nothing was created in the directory and no evidence if ConTeXt trying
anything in particular.

My installation all works fine, though, and the module can be located
and everything. So, have I missed something?

you need to go to the context/base path

Hallo Daniel,

you have to copy the supp-box to the current directory. (And iirc you have 
to have the 'cont-nl' format.)
