How to set section title based on section content?
I have a document that has some structures like this:
\starttext
\startsection[title={Animals}]
\event{\input knuth }
\stopsection
\startsection[title={Books}]
\event{\input knuth }
\stopsection
\stoptext
The event macro runs a bunch of conditionals, deciding which content to
place inside the section. It places any one of neary 200 possible
different types of content there.
Sadly when I wrote the code, I thought generic titles would be okay. Now
I realize I need to be more specific, giving titles that match the
content inside. I could move the section titles inside the \event macro,
but it means rewriting ~200 other macros.
In other words, how do I define a section title by defining it somewhere
in the content of the \event macro?
\starttext
\startsection[\whatistitle] %<-- would display "Neon Tetras"
\event{\thetitleis{Neon Tetras}\input knuth }
\stopsection
\startsection[\whatistitle] %<-- would display "Detective Stories"
\event{\thetitleis{Detective Stories}\input knuth }
\stopsection
\stoptext
When each section contains nothing except the \event command I would
remove the section titles from the document itself and place them as
part of the \event command.
\define[1]\Event
{\startsection[title={#1}]
\input{knuth}
\stopsection}
\starttext
\Event{Neon Tetras}
\Event{Detective Stories}
\stoptext
