before= in setupbuffer

before= in setupbuffer

[Marc van Dongen]

Dear all,

The following:

\def\beforeAnswer{\noindent Answer \number\questionctr \crlf}

\defineblock[answer]
\hideblocks[answer]
\setupblock[answer]
   [before=\beforeAnswer]

Always generates
 Answer 0
at the start of every answerblock.

If I remove the \hideblocks[answer] line, different
lines get printed. Is there any way to get something
similar while still hiding the blocks?

Regards and thanks in advance,

Marc

No.

\defineenumeration[Answer]

\defineblock[Answer]

\beginAnswer
  \startAnswer 
    The Answer is always easy! 
  \stopAnswer
\endanswer

That's the way. A bit more typing, but better. Now, when you call up the blocks, their numbering will nicely be in sync, and, even better, you can cross link them: 

\defineenumeration [Answer]   [coupling=Question]
\defineenumeration [Question] [coupling=Answer] 

You seldom need to define your own macros -)

Before and after are executed when a block is placed, and they normally are used for spacing or tricky font swhitches and so.
