You can use \rawcountervalue[] or 
\convertedcounter[].

No, you don’t need \newcounter because \increment checks if the counter exists 
because it tries to increase the value. The \newcounter command which creates 
the counter can also be used to reset the value and not only to create the 
counter.

Hi Wolfgang,

Thanks for the tip: I’ll try to adapt what you suggest to the case of blocks 
and question-hint-answer, and then let you know if I succeed.
Out of curiosity, how can one access the counter associated to an enumeration 
or an item?

Also, if I understand correctly, the command
\increment\QuestionCounter
creates first a counter named QuestionCounter, if it does not exist yet, and 
then increments its value: so one does not need anymore commands such as
\newcounter\QuestionCounter
before incrementing it. Am I right?

When you have only questions and answers you can use the coupling key but in 
your case something like below is necessary:

\defineenumeration[Question]
\defineenumeration[Answer]

\define\startquestion
  {\increment\QuestionCounter
   \expanded{\startQuestion[reference=Question:\QuestionCounter]}}

\define\stopquestion
  {\stopQuestion
   \par
   \in{Answer}[Answer:\QuestionCounter]}

\define\startanswer
  {\expanded{\startAnswer[reference=Answer:\QuestionCounter]}}

\define\stopanswer
  {\stopAnswer
   \par
   \in{Question}[Question:\QuestionCounter]}

\setupinteraction[state=start]

\starttext

\startquestion
What is the answer to life the universe and everything?
\stopquestion

\page

\startanswer
42.
\stopanswer

\stoptext

If I understand well, one way might be something like (where \theQuestionNumber 
stands for the number given by \startquestion)

\define\StartQuestion{\startquestion[Q:\theQuestionNumber]}
\define\StartHint{\startquestion[H:\theQuestionNumber]}
\define\StartAnswer{\startquestion[A:\theQuestionNumber]}
\define\StopQuestion{\par\in{Hint}[H:\theQuestionNumber]\par 
\in{Answer}[A:\theQuestionNumber]\stopquestion}
\define\StopHint{\par\in{Question}[Q:\theQuestionNumber]\par 
\in{Answer}[A:\theQuestionNumber]\stophint}
\define\StopAnswer{\par\in{Question}[Q:\theQuestionNumber]\par 
\in{Hint}[H:\theQuestionNumber]\stopquestion}

and then using \StartQuestion \StopQuestion, etc, instead of \startquestion 
\stopquestion.
But how can I refer to the \theQuestionNumber set by \startquestion?

Thanks for your time and your attention.

Not without writing your own environment where you generate a unique reference 
for each question, hint and answer.

Hi Jaroslav,

Actually the formatting of what you put in the block determined for example by
\beginanswer
The answer is…

is independent of the block mechanism: you can use whatever structure you want. 
In the example we exchanged on, an enumeration such as
\startanswer

where this \start \stop has been defined by \defineenumeration[answer], but you 
can use your own compact formatting instead of this.

Re: [NTG-context] setuphead for in-paragraph head ?

[Otared Kavian]

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

You have to convert the question, hint and answer environment.

What the block environment does is to save the content from the begin to the 
end block and hides it when you use \hideblocks[…]. To output the content of 
the environments you can use \useblocks[…].


\defineblock[question]
\defineblock[hint]
\defineblock[answer]

\defineenumeration[question][alternative=hanging,text={Question},stopper={.}]

Re: [NTG-context] setuphead for in-paragraph head ?

[Otared Kavian]

Hi Wolfgang,

In mkiv, even using \startanswer, \stopanswer (and the same syntax with 
questions and hints) the blocks mechanism seems to be broken.
The error message is still the following:

\dostopnormalblock ...meter \c!after \par \egroup 
  
 ...fact that $2\times 5 = 10$. \dostopnormalblock 
  \dostartnormalblock {hint}...
\dodowithpar ...dler \v!construction \endcsname #1
  \csname \??constructionsto...

When I understand a little bit more about that mechanism I’ll do other testings 
and eventually ask Hans about what has been changed regarding blocks.
Best regards: OK

Hello Wolfgang, Otared and Aditya.
Thanks for your advice and treatments. It is there a complete working 
example?
I am sorry, but I am not able to achieve the proposed modifications to 
make it work.

Thanx.

Hi Wolfgang, Hi Aditya,

Thanks for your attention.
Unfortunately adding
\keepblocks[question]
the example I sent before does not work in mkiv, and changing
location=hanging
to
alternative=hanging
does not help neither…
The error message in mkiv is:
\dostopnormalblock ...meter \c!after \par \egroup

 ...fact that $2\times 5 = 10$. \dostopnormalblock
\dostartnormalblock {hint}...
\dodowithpar ...dler \v!construction \endcsname #1
\csname \??constructionsto…

So I don’t know what to do if one has to use mkiv.


When you enumerations in this form

\beginanswer
\answer $10$
\endanswer

you have to finish the paragraph, e.g. by adding \par

\beginanswer
\answer $10$\par
\endanswer

or better use the start/stop commands for the enumeration.

\beginanswer
\startanswer
$10$

Re: [NTG-context] setuphead for in-paragraph head ?

[Otared Kavian]

Hi Jean Guillaume,

I guess Marco Patzer and Wolfgang Schuster gave you already the appropriate 
answers.
Nevertheless, I wanted to share with you the definitions I use for the kind of 
work you want to do:

%%% begin example-exercise.tex
%%%
% defining \startexo, \stopexo as an enumeration:
\startsetups style:simple
\defineenumeration[exo]
[alternative=hanging,
width=fit,
stopper={.},
text=Exercise, 
%   between=,
before=, 
after=\blank] 
\stopsetups % style:simple

\startsetups style:textrule
\definenumber[MyExoNumber][way=bysection,sectionumber=yes]
\setuptextrules[rulecolor=darkred]
\define\ExoCommand{\incrementnumber[MyExoNumber]
\textrule[top]{Exercise \getnumber[MyExoNumber]}
\startbackground[frame=off,leftframe=on,backgroundcolor=white,
framecolor=darkred]}

\defineenumeration[exo]
[alternative=hanging,
width=fit,
text={}, 
number=hide,
number=no,
before={\ExoCommand}, 
after={\stopbackground\blank}]
\stopsetups % style:textrule

\definehead
  [Exercise]
  [subsection]
  [alternative=text,
   distance=0.5em,
   insidesection=\ignorespaces]

Re: [NTG-context] setuphead for in-paragraph head ?

[Jean-Guillaume]

But this:

\definehead
  [Exercise] [subsection]
  [after=]
\starttext
  \startExercise [title=This is the exercise's title]
The exercise's content.
  \stopExercise
\stoptext

results to:

1 This is the exercise's title
The exercise's content.

and I would like it to be:

1 This is the exercise's title The exercise's content.

(When I can typeset that, I will see about formatting the number and so on.)

I'm sorry it wasn't very clear. Now I understand that I misunderstood
\startExercise{...} for \startExercise[title=...] and that's why I was
confused about which newline I want to get rid of.

Re: [NTG-context] setuphead for in-paragraph head ?

[Jean-Guillaume]

Thanks for your reply, Marco.

Here is a full example:

 \starttext
 \definehead[Exercise][subsection]
 \setuphead
[Exercise]
[after=]
\startExercise[]{(this is the exercise's title)}
The exercise's content.
\stopExercise
\stoptext


After contexting it, it looks like:

1
(this is the exercise's title) The exercise's content.


Actually, I would like to have the head's number and the head's title
on the same line. That is, whith no new line.

That's controlled by the “after” key.

 \setuphead
  [Exercise]
  [after=]

Please provide full working examples next time. That makes it easier
for us and it's more likely you'll get a response.

That depends on your document. You can use sections, enumerations or
Wolfgang's annotation module.
