[ A long list of feature requests ]

Here is something that was not in my original list: subformula numbering.

[...]

I was thinking of a better (rather more familar) way of treating subformulas by imitating the \begin{subequations} .... \end{subeqations} environment of latex.

I propose a \startsubformula .... \stopsubformula environment, so that inside it, I will get subformula numbers rather than formula numbers. Having discovered conversions (see my previous mail on tagged formulas), I tried to implement it using conversions. The following straightforward approach works fine. This is just a stop gap code, I do not take care of inherting the right settings for formulas, but it conveys the idea.

Hans and Taco, can something like this be added to the core? If so, I will try to make this macro more robust (correct inheritence, etc.)

Here is a more robust version. I use \??sf as a namespace for subformulas. I do not think that this is used anywhere else.

I found nothing where \??sf is used in the ConText core, but it is defined as systemvariable in mult-sys line 552.

--> \definesystemvariable {sf} % SpeciFics

You should ask Hans if he need it.

core-env.tex : 6 : {\long\setvalue{\??sf#1}{#2}} core-env.tex : 12 : \getvalue{\??sf#1}\relax core-env.tex : 15 : \getvalue{\??sf#1}\relax on my machine Hans -- ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
