Hi all, Hans, here is a bug that remains with the new structure code after Hans fixed many things two weeks ago. I want a counter that is reset at every odd chapter. This works as expected in mkii (and used to work in mkiv), but complains about a "Missing number, treated as zero" and fails to compile in current beta: \setupcolors[state=start] \setuphead [section] [command={{\determineheadnumber[section]}\ifodd\currentheadnumber \resetSlideNumber\incrementSlideNumber \else\incrementSlideNumber \fi}, expansion=yes] \definelabel[SlideNumber][headstyle=normal,way=bytext] \define\SLN{\color[red]{ [\nextSlideNumber]}} \starttext \section{One} should be 2: \SLN \section{Two} should be 4: \SLN \section{Three} should be 2 again: \SLN \section{Four} should be 4 again: \SLN \stoptext Even if you comment out the command=... line, you'll see that labels in mkiv still don't quite do what they should. All best Thomas

ok, fixed in the beta the problem is that the old code was somewhat crippled as it uses this two step method (determine and usage) due to expansion issues in the current beta mkiv code we can do: \setuphead [section] [after=\setups{section:after}, expansion=yes] \startsetups section:after \ifodd\namedheadnumber{section}\relax \resetSlideNumber\incrementSlideNumber \else \incrementSlideNumber \fi \blank \stopsetups btw, you misuse 'command' which in turn has side effects; use after instead ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

\setuphead [section] [after=\setups{section:after}, expansion=yes]
\startsetups section:after \ifodd\namedheadnumber{section}\relax \resetSlideNumber\incrementSlideNumber \else \incrementSlideNumber \fi \blank \stopsetups
btw, you misuse 'command' which in turn has side effects; use after instead
OK, thanks a lot Hans! Have replaced "command" with "after"; now my test document compiles cleanly. Two questions though: \nextSlideNumber used to simply expand to "2" "3" etc. Now I get "SlideNumber 1.2" "SlideNumber 1.3." How can I get the old behavior back? And: I'm doing this in xml documents, and here, the counter is not reset. I assume you want a new example document :-) All best Thomas

yeah you need to reset the prefix, like prefix=no ; depends a bit on your definition (i need to figure out a proper default scheme for a whole doc which is kind of tricky since we have more control now) ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Oops, I am sorry, resetting the counter works in my xml files as well; I had a second after= assignment which confused ConteXt. It's almost perfect, but there's a spurious space creeping in somewhere. Reusing my old example: \startsetups section:after \ifodd\namedheadnumber{section}\relax \resetSlideNumber\incrementSlideNumber \else \incrementSlideNumber \fi \blank[0*line] \stopsetups \setuphead [section] [after=\setups{section:after}, page=yes, expansion=yes, before={\blank[0*big]}] \definelabel[SlideNumber][headstyle=normal,way=bytext,prefix=no,text=] \define\SLN{\color[red]{[\nextSlideNumber]}} \starttext \section{One} should be 2: \SLN \section{Two} should be 4: \SLN \section{Three} should be 2 again: \SLN \section{Four} should be 4 again: \SLN \stoptext Thanks for your help, and best wishes!
