[NTG-context] Misplaced \widehat and \widetilde in mkiv?
Hi Hans,
It seems that with the latest beta mkiv, version
ConTeXt ver: 2014.01.23 01:55 MKIV beta fmt: 2014.1.23
\widetilde and \widehat in mathmode are misplaced (and this is so in any of the
fonts I tried).
Please compare the result of the following in mkii (where everything is
correct) and in mkiv:
begin tilde-hat.tex
\starttext
We set ${\widetilde n}(t) := n(1 - t)$, and ${\widehat u}(\xi) := \int_{{\Bbb
R}}\exp(-{\rm i}x\xi)f(x)dx$.
\stoptext
end tilde-hat.tex
The attached PDF is obtained with mkiv.

[NTG-context] \placeinital special case
Hello, I came across a special case where \placeinital would need some tuning. (It was found in Eglinton, G. and Calvin, M. (1966) Chemical Fossils, Scientific American 216, 32-43.) In the following minimal example, the period following the capital W should be dropped as well, being kept associated with the initial. \starttext \placeinitial W. H.

So far he has located only four lakes, two in the U.S. and two in Africa, that seem to be reasonable candidates. \stoptext This curiosity is by no means an important problem, and perhaps one can identify other such cases (but I have not thought much about it!).

[NTG-context] runtime problem with metafun() code
Hi,
I try to create a Metapost path in lua and it works so far for the
attached example. But a call of that function from another lua function
sadly fails (no path visible after call). The code seems to be executed
later (the output from 'show pid;' appears somewhere later in the log).
How can I ensure that the code is executed at runtime?

Thanks Hans for the quick fix (I tried a dozen different fonts, and they are
all fine).

[NTG-context] setupalign and flushbottom
Dear list,
according to the wiki and the ConTeXt manual, the ConTeXt equivalent
for the LaTeX \flushbottom command is \setupalign[line]. However in my
tests this setting doesn't have the desired effect. For example:
\setuplayout[height=720pt]
\setuphead[subject][before={\vskip4pt plus 1fil},after={\blank[small]}]
\setupalign[line]
\showgrid
\starttext
\dorecurse{3}{\input knuth}
\subject{My Subject}
\dorecurse{8}{\input knuth}
\stoptext
Here at the first page there is a small gap between the last line and
the page border, although the glue above the heading can safely be
expanded to make the page filled. However I do get the desired result if
I replace \setupalign [line] with a low-level command (\alignbottom).
So what is the correct way to get pages bottom-aligned in MKIV?

[NTG-context] \placeinitial after a heading
Hi,
If I attempt to insert a drop cap after a heading while the paragraph
indentation is enabled, I get the following effect: all lines the drop
cap spans except the first one (e. g. second and third in case of n=3)
get an additional indent, equal to the \parindent. For example:
\setupinitial[font=Bold sa 4,n=3]
\setupindenting[yes,1em]
\starttext
\section{Knuth}
\placeinitial
\input knuth
\stoptext
I suppose this is not the intended behavior :) The problem doesn't
occur if I enable indenting also for the first paragraph after the
heading, but in this case, of course, the drop cap itself is indented
together with its adjacent lines. So the following workaround is
possible:
\setupinitial[font=Bold sa 4,n=3,
hoffset=\parindent,distance=-\parindent]
\setuphead[section][indentnext=yes]
Nevertheless it would be nice if this issue could be fixed.
Also, is it possible to explicitly apply case conversion commands to a
drop cap? Setting the 'style' option to \WORD or \word currently seems
to have no effect.
