Hello,

values of number and title of the current (sub...)section can be received by \structurenumber and \structuretitle commands.

Is there a way how to get these values by Lua?

Suppose:

----
\starttext
   \section{Sec 1}
   % Now "\structurenumber" yields "1" and "\structuretitle" gives "Sec 1"

   % How to get "1" and "Sec 1" from Lua?

   \startluacode
     print(0, context["structuretitle"])
     print(1, context["structuretitle"]())
     print(2, context.getvalue("structuretitle"))
     print(3, context.constants("structuretitle"))
     print(4, context.variables("structuretitle"))
   \stopluacode
\stoptext
----

My attempts don't give any useful value (or some of them are even erroneous).

I have no idea how to get the texts "1" and "Sec 1".

Any hints would be appreciated...

Best regards,

Lukas
