MKIV bug

MKIV bug

[Yue Wang]

Hi, Hans

Using context=experimental, the following cross references all appear as ??
MKII works fine.


\placeformula \startformula \startalign
 \NC v \NC = u + at \NR[eq:v]
 \NC h \NC = ut + \frac12 gt^2 \NR[eq:h]
\stopalign \stopformula
Equation (\in[eq:v]) tells the final velocity after
time $t$ and equation (\in[eq:h]) tells the distance
travelled in time $t$.

But it works fine here with both context=experimental and
context=beta. The versions are ``2009.01.17 00:15'' for experimental
and ``2009.01.14 11:29'' for beta.

Appears fine here as well, with context 2009.01.17 00:15. But I assume
your test file was longer thatn just the little block below. Perhaps
you should post a full file.

Btw, the example breaks with cont-xp, but in a different way:
it throws an error at me about an undefined control sequence
(\currentformulassynchronize).

Best wishes,
Taco

OK, in fact the whole file is just add \bye at the end of that piece of code.

This works well on both mkii and mkiv:
\starttext
\placeformula \startformula \startalign
 \NC v \NC = u + at \NR[eq:v]
 \NC h \NC = ut + \frac12 gt^2 \NR[eq:h]
\stopalign \stopformula
Equation (\in[eq:v]) tells the final velocity after
time $t$ and equation (\in[eq:h]) tells the distance
travelled in time $t$.
\stoptext

and this only works in MKII, not mkiv:
\placeformula \startformula \startalign
 \NC v \NC = u + at \NR[eq:v]
 \NC h \NC = ut + \frac12 gt^2 \NR[eq:h]
\stopalign \stopformula
Equation (\in[eq:v]) tells the final velocity after
time $t$ and equation (\in[eq:h]) tells the distance
travelled in time $t$.
\bye


Another problem which I reported a few weeks ago is still not solved.
when I use a sans font, like \setupbodyfont[iwona, ss,12pt], the label
for the equation still uses roman font unless i manually change them
by \setupformulae. I think this can be improved.

Why do you expect ConTeXt to work without \start|stoptext ?

Hi,

Well, it used to work, and i use it a lot in my own document.
(both mkiv and mkii support this before the 2008.11.10 version)

start/stoptext is really needed in order to let multipass info work
