[NTG-context] typo in startformulas in latest beta
Hi Hans,
There is a missing carriage return in the definition of
\startformulas in the latest beta.
In \def\startformulas#1\stopformulas
\long\def\startformula##1\stopformula
{\advance\scratchcounter\plusone}% \scratchcounter\zerocount #1%
preroll
should be
\long\def\startformula##1\stopformula
{\advance\scratchcounter\plusone}% --- Missing \cr here
\scratchcounter\zerocount #1% preroll
This causes a number to missed in
\starttext
\placeformula

Dear ConTeXters,
1/ I would like to use a named formula with a reference containing
several subformulae each with a reference. The closer I can get to is to
add an empty namedformula followed by subformulae (see test file below).
How can I get rid of the empty line with a number in the pdf ?
I took a different approach to this. I had written some macros that do
automatic subformula numbering, and I added a macro there to do have a
named subformulas. See the code at the end.
4/ How can I redefine the \vec command in my formulae without having a
warning system : command \vec is already defined
\def\vec#1{whatever}
will not give you a warning. You get a warning only if you use
\define.
5/ I do like a lot the minimum distribution so easy to install. It would
be even better if bibtex can be added. It's only 82.8 KiB
bibtex is part of the minimal distribution for windows. It is in
texmf-mswin/bin/
Now, coming back to the code for subformulas. I defined a
\startnamedsubformulas[tag]{name} to take care of named subformulas.
This is build on top of an existing \startsubformulas ...
\stopsubformulas that do automatic numbering of subformulas. See the
examples in the end.

Re: [NTG-context] TABLE in item
\let\beforeTABLEsplitbox\relax
\let\afterTABLEsplitbox \relax
\let\beforeTABLEbox \relax
\let\afterTABLEbox \relax
you can play with these macros since they are the formal hooks
Hans,
I played with
\let\beforeTABLEsplitbox\dontleavehmode
\def\afterTABLEsplitbox{\relax\dontleavehmode}
\let\beforeTABLEbox\dontleavehmode
\let\afterTABLEbox\relax
which gives the right indents but stops the tables splitting.
I think I will just have to live with non-splitting tables for now,
unless you can suggest a better redefinition?
Thanks very much for the help anyway.
