currentheadnumber / doif.. problem

currentheadnumber / doif.. problem

[Peter Schorsch]

Hi,

I tried to get the full present heading-number. If I am using currentnumber
the result is only the last part of the heading-number. So I tried do
implement a function like this:

\def\presentheadnumber%
        {\doifelse{\headnumber[section]}{}%
                {\headnumber[chapter]}%
                {\headnumber[section]}%
        }

but always the else-part is executed. I also tried to use doifemptyelse,
doifnumber etc.. but as soon i am using headnumber[...] only the else-part
will be executed. Can anyone help me with this problem? Or am I going a
complete wrong way?

Thanks

Can you create a minimum example to play with?

I attached the module t-pararef.tex and the example pararef-test.tex. The ref1 
is still wrong. 

When I replace \currentheadnumber in \paragraphMark with the before defined 
\presentheadnumber  context is saying that a «Missing control sequence 
inserted» - but I don't see any mistake there (but there must be)...

But finally I only want that the ref1 in the example is also working (see at 
the end of example file).

A second questions: why is the paragraph of ref3 in the example indented?

Thanks, P.

Re: currentheadnumber / doif.. problem

[Peter Schorsch]

ok,

I found the solution. In the documentation (cont-eni.pdf) at page 172 
following is written:

For example:
\currentheadnumber   : 8.3
\headnumber[chapter] : 8
\headnumber[section] : 8.3

but that is partly wrong. There should be standing (change example from 8.3 to 
8.3.2):

For example:
\finalsectionnumber : 8.3.2
\currentheadnumber   : 2
\headnumber[chapter] : 8
\headnumber[section] : 8.3

Or are \finalsectionnumber and \currentheadnumber interchanged in the code and 
the documentation is as it should be? But that is a question I cannot answer.

Ciao, P.

I don't have much time to investigate properly but there should be a 
\complexheadnumber defined in core-sec which gives you what you need. 
This should be tied to \headnumber though, so if that doesn't work it 
may be to do with where or how you are using the command. Do you have a 
complete minimal example document?

currentheadnumber / doif.. problem

[Peter Schorsch]

Hi,

I tried to get the full present heading-number. If I am using currentnumber
I am getting back only the last part of the heading-number. So I tried do
implement a function like this:

\def\presentheadnumber%
        {\doifelse{\headnumber[section]}{}%
                {\headnumber[chapter]}%
                {\headnumber[section]}%
        }

but always the else-part is executed. I also tried to use doifemptyelse,
doifnumber etc.. but as soon i am using headnumber[...] only the else-part
will be executed. Can anyone help me with this problem? Or am I going a
complete wrong way?

Thanks
