I try to replicate the following :
https://mailman.ntg.nl/pipermail/ntg-context/2006/021038.html (i.e. the
equivalent of \tag in latex/amsmath). More precisely this:
> %------------------------8<--------------------------
> \def\placeformulatag%
> {\dosingleempty\doplaceformulatag}
> \def\doplaceformulatag[#1]#2%
> {\let\normalstopformula\stopformula
> \def\stopformula%
> {\normalstopformula
> \restorenumber[formula]
> \egroup
> \let\stopformula\normalstopformula}
> \bgroup
> \savenumber[formula]
> \def\dummyconversion##1{#2}
> \defineconversion[dummyconversion][\dummyconversion]
> \setupformulas[conversion=dummyconversion]
> \placeformula[#1]}
>
> \starttext
> \placeformulatag[tag]{test} \startformula
> E = mc^2
> \stopformula
> See \in formula[tag] for a tagged formula
> \stoptext
> %----------------------------8<-------------------------
However, the following (simpler) code produce an "Undefined control
sequence" when using \in command.
\starttext

> \def\a#1{test}
> \defineconversion[a][\a]
> \setupformulae[numberconversion=a]
> \placeformula[test]

> \stoptext
The following code, does not produce the error, but is not practical for
the reproducing the \tag command.

What am I doing wrong? I guess the command \a is no longer defined when the
compiler hit \in but how can I ensure that such local definition stay
accessible ?
Thank you in advance,
