Extra vertical space in intertext

Extra vertical space in intertext

[Aditya Mahajan]

Hi,
  There is an extra vertical space in the first set of formulas, while 
the vertical spacing in the second set appears to be fine. I can not 
figure out why this should happen. Even if you comment the 
setupformulas line, the first set of formulas seem to allocate more 
space for the intertext.

\setupformulas[align=right,spacebefore=none,spaceafter=none]
% There appears to be extra space, even if I put 
% spacebefore=spaceafter=big
% align = right is for visualization purpose only
\starttext
\startTEXpage
\startformula \startalign
   \NC A \NC B \NR
   \intertext{test}
   \NC C \NC D \NR
\stopalign \stopformula
test outside formula
\startformula \startalign
   \NC A \NC B \NR
   \intertext{test}
   \NC C \NC D \NR
\stopalign \stopformula
\blank[big]
\startformula \startalign
   \NC \int_0^1 \NC B \NR
   \intertext{test}
   \NC \int_0^1 \NC D \NR
\stopalign \stopformula
test outside formula
\startformula \startalign
   \NC \int_0^1 \NC B \NR
   \intertext{test}
   \NC \int_0^1 \NC D \NR
\stopalign \stopformula
\stopTEXpage
\stoptext

And what is happening with the start stop TEX page here. Why is the 
last line cut off!

Thanks,
Aditya

looks ok here 

it's a \framed thing, so you may have side effects due to math axis or so 

(maybe i should make it a stream)

That is related to \openup. Adding \def\displayopenupvalue{0pt}
makes (nearly) all whitespace go away.

Because of some vertical whitespace trickery context does, it
needs something to set off against.

   \stopalign \stopformula
   ~
   \stopTEXpage

That is a bit silly, but the fastest thing I can come up with.


Cheers,
Taco

Should this be included in the definition of \dointertext (or 
\forgetall) or would that be too drastic?

The problem with TEXpage is not only related to math. Another example
with strange results:

\starttext
\startTEXpage
\chapter{Bla}
Hello world!\crlf
Hello world!
\stopTEXpage
\stoptext

I guess that \startTEXpage should be fixed before you start hacking
any math settings.
