Re: [NTG-context] Numbering subformulas

6 Aug 2015

      Hello Wolfgang,

thank you for the patch (not in today's beta); I also attach the modified strc-mat.mkiv and a test file.

Two questions:

1.

What exactly are

   %\startsubformulas[+]       % These two options for \subformulas
   %\startsubformulas[mylabel] % enable subnumbers for the formulas

intended for?

The simple "\startsubformulas[eq:b]" meets my needs (subformulas are sub-numbered) and I can't see any difference to "\startsubformulas[+]".

2.

Is there a way to setup numbering subformulas to "(1a)" form instead of "(1.a)", i.e. set the separator to ""?

Best regards,

Lukas

that it is not working with the latest beta.
You have to make three changes in strc-mat.mkiv to fix subformula numbering.
The first change is necessary to show the even when there isn’t a
argument for \startsubformulas.
The second change is necessary to prevent context from reseting the mode
for subnumbers
at the end of each formula.
The changes in \stopsubfomulas is necessary because of the test in
\everyresetformulas.
