You can try the \currentstrcuture… commands but I don’t know if the are meant as user level commands.

\starttext

\chapter{Chapter}

\starttabulate
\NC Name \EQ \currentstructurename \NC\NR
\NC Level \EQ \currentstructurelevel \NC\NR
\stoptabulate

\section{Section}

\starttabulate
\NC Name \EQ \currentstructurename \NC\NR
\NC Level \EQ \currentstructurelevel \NC\NR
\stoptabulate

In case I haven't told you before: you are awesome!

This is exactly what I was looking for. Due to this I also found \currentstructurereference and a bunch of other commands :)
Once you know that "structure" is the keyword, "strc-sec.*" is just around the corner.

Regarding your earlier mail (\definesectionlevels ...):
Wow, there is really a lot of "hidden" functionality in ConTeXt. If you lay out the document with these commands from the beginning, that really eases restructuring tasks. However the readability (of the source code) slightly falls off. I will evaluate this further. Thanks for this too :-)

 Hello,
 
 again I'm working on a technical manual and decided to use ConTeXt to do the 
 job. Since I'm a developer, I always try to do things as flexible as possible.
 
 I'm currently struggling to achieve two things:
 
 1) a macro (that will print a list) should also add a heading. However, the 
 heading should always be one level beneath the current heading and without 
 numbering. Example: within a \section it should be a \subsubject, within a 
 \chapter it should be a \subject, and so on.

\definesectionlevels[extra][title,subject,subsubject,subsubsubject]

\setuphead[chapter][color=red]

\setuphead[subsection][color=blue]

\define\PlaceList

[NTG-context] Dynamic headings query heading information

Title: Dynamic headings  query heading information


Hello,

again I'm working on a technical manual and decided to use ConTeXt to do the job. Since I'm a developer, I always try to do things as flexible as possible.

I'm currently struggling to achieve two things:

1) a macro (that will print a list) should also add a heading. However, the heading should always be one level beneath the current heading and without numbering. Example: within a \section it should be a \subsubject, within a \chapter it should be a \subject, and so on.

2) another macro should build an index at the end of the document. I use Lua to keep a list of all database tables referenced within the document (together with some metadata) and save it in the jobpasses struct. Now I also want to track the chapters, sections, etc where these references are, to be able to see, where a database table is used.

To solve these two problems, I'm looking for information about the current heading. The level and the associated reference name.
If I have the level, I can keep my own list of necessary heading types (subject, subsubject, ...) and just get the one at level+1 to write the heading using lua (tex.sprint()).
With the reference name I can obviously solve 2), since I then can simply keep a list for each db table in the jobpasses structure.

I'm open for different suggestions, since I may miss an (obvious?) alternative. And as you can also probably see, I like Lua pretty much, so a solution requiring Lua is not a problem :-) (quite the contrary actually)


Best regards,
Andreas
