[NTG-context] defining font family for several options
Perhaps someone can assist me with the following query. I have a
situation where I need to use more than one sans serif fonts (especially
within complicated chapter heads). I currently have the following:
\definefontfamily [mainface] [rm] [alegreya]
\definefontfamily [mainface] [ss] [dax][tf=file:dax-regular]
\definefontfamily [mainface] [mm] [alegreya]
\setupbodyfont[mainface]
\setupbodyfont[11pt]
But what if I need to have, in addition to the Dax sans serif typeface,
an additional sans serif typeface such as ITCAvantGarde? How do I
declare that? Do I just give it another name, e.g.
\definefontfamily[chapter][itcavantgarde] etc? If I did that, how then
do I refer to it? Obviously not just as {\ss my text} since that would
call in the dax font.

Re: [NTG-context] new upload
Hi, Hans. :)
Is there an analogue for display math? Could discretionaries be applicable
to math formulas when "split=yes" is enabled, for instance?
Thank you in advance.
Jairo :)

[NTG-context] LuaMetaTex dereferences NULL pointer

with the latest LuaMetaTeX upload (running on Linux x64),

[NTG-context] new upload
Hi,
In order to keep the 'context is good for toy math' reputation up to
date, in lmtx we can now have proper discretionaries in math and math in
discretionaries. The kind of things no one asks for but they might be
useful in educational settings.
Here are some examples ():
\starttext
\showframe
\enabletrackers[math.toysymbol]
\definemathtoysymbol[Plus] [bin][+]
\definemathtoysymbol[Minus][bin][-]
\definemathtoysymbol[Equal][rel][=]
$\dorecurse{199} {
x_{#1} \ifodd#1\relax\Plus\else\Minus\fi
} x_{200} \Equal n$
\blank
\dorecurse{10} {
test \discretionary
{\darkred hel $\sqrt{y}$ lo}
{\darkgreen good $\sqrt{z}$ bye}
{\darkblue wel $\sqrt{x}$ come} test
}
\blank
\dorecurse{10} {test me #1
$x + 2x \discretionary class 2
{$+ \, \cdots $}
{$ \cdots \, +$}
{$+ \, \cdots \, +$} nx$ test
}
\stoptext
You might be able to guess from this code what is supposed to happen.
I'll play a bit more with this later (assuming that it's somehow
useful). We could predefine a bunch. As usual there might be issues but
I'll sort them out when we run into them (it's a non critical feature
with not much impact).
