Dear all,
Is it possible to have a sort of « local references for formulas » or else to clear previous references to formulas at a certain point?
In a chapter where a certain number of exercices and formulas are to be numbered, assume I have the following minimal example
%%%%%%%%% begin
\starttext
Exercice 1. Prove that if $ab=ba$ and $2ab=0$ then
\placeformula[eq:1]
\startformula
(a+b)^2 = a^2 + b^2.
\stopformula
Using the identity (\in[eq:1]) prove that $(a=b)^{2n} = a^{2n} + b^{2n}$.
\blank[big]
\hrule
\blank[big]
Exercice 2. Prove that for any integer $n$
\resetnumber[formula]
%\reset[formulas][references]
\placeformula[eq:2] % I would like the reference to be [eq:1]
\startformula
(\cos(x) + {\rm i}\sin(x))^n = \cos(nx) + {\rm i} \sin(nx).
\stopformula
Using the identity (\in[eq:2]) % I would like here to say [eq:1]
compute $\cos{3x}$.
\stoptext
%%%%%%%%% end
I would like to be able to have the equations numbered within each exercise (which is in fact defined through an enumeration environment), and be able to have the reference to each formula « local » within that exercise.
The resaon is that the execises and problems may have several equations which are referenced to with [eq:1] through [eq:10] (say…), and have been prepared and given previously to students on independent sheets. When I want to give out a booklet of all the exercises, then it would be handy to have such a feature.
I understand that I am not being very clear… Hope someone would understand what I mean and need :-)
Best regards: OK

I looked up the chapter on references of the main manuel written by Hans, but unfortunately I could not find a solution, or could not adapt what is said there. It can be that I have to change my approach of defining my « exercises », for instance by defining each exercise as a section or subsection? Up to now I have two ways of defining an « exercise »: • one is with \defineenumeration[Exo] (when using mkii), • the other one is with \defineannotation[Exo] and your annotation module when using mkiv. In neither case the command \setupreferencing[prefix=+] or \setupannotation[Exo][prefix=+] seems to generate local tags. Just in case, below is a minimal file, which shows how I use the annotation module.

There are a few fixes needed in the mechanism but as you can see below it works when you know what’s wrong but to complete the function for MkIV Hans needs a shorter example. \setupinteraction[state=start] \usemodule[annotation] \define[2]\ExoSetup {%doifsomething{\annotationparameter{prefix}}{\setupreferencing[prefix=\annotationparameter{prefix}]}% \doifsomething{\annotationparameter{prefix}}{\setupreferenceprefix[\annotationparameter{prefix}]}% \doifsomething{\annotationparameter{prefix}}{\setupformulas[referenceprefix=\annotationparameter{prefix}]}% \resetnumber[formula] \textrule{#1}% \startframedtext[width=\textwidth,frame=off,leftframe=on]% #2% \stopframedtext} \defineannotation [Exo] [alternative=command, command=\ExoSetup, text=Exercise , number=yes, headcolor=darkred] \starttext \startExo[prefix=CharacTwo] Prove that if $ab=ba$ and $2ab=0$ then \placeformula[eq:1] \startformula (a+b)^2 = a^2 + b^2. \stopformula Using the identity (\in[eq:1]) prove that $(a=b)^{2n} = a^{2n} + b^{2n}$. \stopExo \page \startExo[prefix=Moivre]{Moivre's formula} Prove that for any integer $n$ \placeformula[eq:1] \startformula (\cos(x) + {\rm i}\sin(x))^n = \cos(nx) + {\rm i} \sin(nx). \stopformula Using the identity (\in[eq:1]) compute $\cos{3x}$. \stopExo \page \starttabulate[|Tl|l|] \NC eq:1 \NC \in{Equation}[eq:1] \NC\NR \NC CharacTwo:eq:1 \NC \in{Equation}[CharacTwo eq:1] \NC\NR \NC CharacTwo:eq:1 \NC \def\referenceprefix{CharacTwo}\in{Equation}[eq:1] \NC\NR \NC Moivre:eq:1 \NC \in{Equation}[Moivre eq:1] \NC\NR \NC Moivre:eq:1 \NC \def\referenceprefix{Moivre}\in{Equation}[eq:1] \NC\NR \stoptabulate \stoptext Wolfgang ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 4+ messages in thread
