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

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)

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!
Thomas
