Re: setuphead for in-paragraph head ?

[Otared Kavian <otared@gmail.com>]

Hi Wolfgang,

Many thanks for your attention and insight.
With your code everything works as expected. In case others would be interested, I give here a slight modification of what you sent, which works very well with mkiv: I only added 
	\setupblock[question][before={\startquestion},after={\stopquestion}]
so that one can just say \beginquestion \endquestion without having to enter each time \startquestion \stopquestion. I don’t know whether this is a good idea or not, as it may have side effects…

I will put this example on the wiki, but before doing so I have another question:
can one add two automatic links at the end of each question so that one can navigate easily to the respective hint or answer corresponding to that question? Indeed if this were possible, one would add also two automatic links to each hint going to its question and the corresponding answer, and two other links to each answer going to its hint and question. One can do this manually by adding a reference to each question, each hint and each answer, but it would be nice to have this done automatically.

Best regards: OK
PS: here is the complete example for question-hint-answer:

%%%% begin question-hint-answer-blocks.tex
\defineblock[question]
\defineblock[hint]
\defineblock[answer]

\defineenumeration[question]
	[alternative=hanging,
	width=2.5cm,
	text={Question},
	headstyle={\bi},
	stopper={.}]
	
\defineenumeration[hint]
	[alternative=hanging,
	width=4cm,
	text={Hint for question},
	headstyle={\bi},
	stopper={.}]

\defineenumeration[answer]
	[alternative=hanging,
	width=4.5cm,
	text={Answer to question},
	headstyle={\bi},
	stopper={.}]

\setupblock[question][before={\startquestion},after={\stopquestion}]
\setupblock[hint][before={\starthint},after={\stophint}]
\setupblock[answer][before={\startanswer},after={\stopanswer}]

\keepblocks[question]
\hideblocks[hint]
\hideblocks[answer]

\starttext

\section{Questions}

\beginquestion
  Compute $4\times 5$.
\endquestion

\beginhint
  Use the fact that $2\times 5 = 10$.
\endhint

\beginanswer
  $20$.
\endanswer

\beginquestion
  What is the value of $100 / 10$?
\endquestion

\beginhint
Remember that $10\times 10 = 100$.
\endhint

\beginanswer
$10$
\endanswer

\section{Hints to all questions}

\useblocks[hint]

\section{Answers to all questions}

\useblocks[answer]

\stoptext
%%%% end question-hint-answer-blocks.tex
