DIY toc (or similar list)

DIY toc (or similar list)

[Thomas A. Schmitz]

Hi experts,

I'm thinking about a new presentation style and need some general advice from the TeXperts. I would like to have a list of topics on some area of the slide (similar to s-pre-19.tex). However, if at all possible, I would like it to be a bit fancier. Let's say I want the list of topics typeset in gray frames in a black font, but the current topic in a blue frame with a white font. Would this be possible with something like \definelist? Is there any notion of "currentlistitem" or "currentmarking" in such lists? Or, even better: would it be possible to have access to the single members of a list and maybe compare them to a current value and then typeset them accordingly? Something like this pseudocode:

for member in topiclist do
  if member == currentvalue
     <some fancy framing and metapost stuff with member>
  else
     <less fancy but still nice-looking metapost stuff>
  end
end

Or am I trying to reinvent the wheel here? I would be happy to hear any ideas on that. 

All best

Thomas

you can do something like this (not sure if it works):

\setuplist[...][alternative=command,command=\MyFancyListentry]

\define[3]\MyFancyListentry
   {\doifelse{#2}{\fullstructureheadtitle} % is this the correct value?
      {...}% fancy layout
      {...}% normal layout
    ...}

Wolfgang, thanks a lot! I could adapt your code so it does what I want! Here's what I have now, I'm sure I can run with that for the presentation stuff. Thanks a lot, and best wishes!

Thomas


\definelist[MyTopics][criterium=all]

\define[3]\FancyEntry
 {\doifelse{#1}{\MyMark} %
    {\color[blue]{#1}}% fancy layout
    {\color[red]{#1}}% normal layout
\par}

\setuplist[MyTopics]
          [style=\tfxx,
           pagenumber=no,
           alternative=command,
           command=\FancyEntry]


\def\Topic#1{%
  \def\MyMark{#1}%
  \writetolist[MyTopics]{#1}{}%
  \completelist[MyTopics]%
}

\starttext

\Topic{First}

Hello 1

\page

\Topic{Second}

Hello 2

\page

\Topic{Third}

Hello 3
