[NTG-context] packslashes not working in latest beta
Dear list,
I have the following sample:
\enabledirectives[hyphenators.urls.packslashes]
\starttext
\hsize\zeropoint
\hyphenatedurl{http://www.pragma-ade.com}
\stoptext
Using latest beta (2018.04.19 15:53), the directive doesn’t seem to
work. (The two contiguous slashes are placed in different lines.)
Can anyone confirm this?
Many thanks for your help,
Pablo

Well yes, I already suspected this when I saw "italic" in the log.
What would be a better approach?
The question who started the investigation wanted to get a binary
symbol "\hat{\otimes}". How does one define it so the spacing is
correct? It doesn't need be the fontloader that catches all the
case. It would be quite okay to insert some code that says "hey
handle me like \otimes". And it would also okay to assume a "good
font".
But even with cambria it doesn't work correctly in context
currently. The displacement is slight (only 0.3pt) but at large zoom
one can see it:
%\setupbodyfont[cambria] %without it the spacing is more pronounced
\starttext
$ V \otimes W $
$ V \mathbin{\hat{\otimes}} W $
$ V \Umathchar 2 0 "2297 W $
$ V \mathbin{\Umathchar 0 0 "2297} W $
$ V \mathbin{\Umathchar 2 0 "2297} W $
$ V \mathbin{\Umathaccent 0 0 "302 \Umathchar 0 0 "2297} W $
\stoptext

Can one avoid this side effect of nested \math-command? When
building symbols it is not always easy to avoid such nestings.
it becomes a chicken-egg issue because one can argue that a wrapped
mathbin is no longer a pure bin and so ... it's again an indication that
a wrong boundingbox (width) relying on always some kind of italic to fix
it is a bad approach and recursively going into a bin (or whatever) node
to see if there is a nucleus chactacer would be yet another
'configureble option' ... all is possible but the more we get of that
the more one needs to be aware of it and provide control over the
opposite (keep in mind that such control is then a formula wide one as
math lists are only processed when fully collected)
