Those math semantic sanfs-serif styles were added because in some types of 
applied math, they are required, as in the standard I indicated in another 
thread. However, the OP did not indicate their use.

There is support for hvmath (a virtual unicode font is constructed 
then) but you need to get those files somewhere.


An alternative is to roll out your own virtual math font (take a look 
at the *.lfg files that have math in their name).


On the agenda for the tex gyre project is a serif math font (lato or 
so) but that will take a while (also awaits funding).
The font fallback mechanism is another alternative but one shouldn’t 
expect too much because a real sans serif math is necessary to get 
larger operators.

Re: [NTG-context] basic fontsizes question

[Wolfgang Schuster]

Hi Thomas,

please the following article when you have your next question: 
http://www.shlomifish.org/philosophy/computers/netiquette/email/start-new-thread.html

Thomas Fehige 
6. Juni 2016 um 16:05

In the fonts book I found the \definebodyfont command, but it does not 
to do what I expected. What I need (for a poster) is a set of absolute 
font sizes. I tried the code below. I put some quirks in, like the 
huge value for "a", to see if it works, but it doesn't. It just uses 
the preset proportions relative to the preceding fontsize command (in 
the example, \tfx is bigger than \tf).


\definebodyfontenvironment[palatino][24pt][

text = 24pt,

small = 22pt,

x=22pt,

scriptscript = 16pt,

xx = 16pt,

big=28pt,

a = 80pt, % 28pt

b = 40pt,

c = 50pt,

d = 50pt,

interlinespace = 3ex,

em = italic

]

\setupbodyfont[palatino,24pt]

\starttext

\tf tf\\

\tfa tfa\\

\tfb tfb\\

\tfx tfx\\

\tfx tfx

\stoptext


When you have only a small amount of text the use of 
\definebodyfontenvironment is overkill because you can use the 
\definedfont command to set a certain font size.


\starttext

\start \definedfont[Serif at 20pt]
\input ward
\stop

\startfont[SansBoldItalic at 18pt]
\input ward
\stopfont

\stoptext

The STIX fonts have them, except for non-bold Greek it seems, but they must be 
accessed directly, either by typing directly in UTF-8, or somehow redefine them.

Re: [NTG-context] Partial \framed

I'm trying to put a piece of text in a partial frame that's meant to 
look like square brackets aligned with the left and right edges of the 
textblock.


I tried to use two \framed constructions inside each other, the outer 
one with width=textwidth and negative toffset and boffset, the inner 
one with a smaller width, a fat rulethickness and the color of the 
background, expecting it to erase the outer frame where it's not needed:


\color[zier]{%

\framed[%

align=middle,

width=\textwidth,

toffset=-4mm,

boffset=-4mm,

strut=no,

]{%

\color[paper]{\framed[%

align=middle,

width=222mm, % i.e. \textwidth-4mm

toffset=6mm,

boffset=5mm,

rulethickness=5mm

]{%

\color[zier]{\tfd \strut Here's the text that is menat to look 
important; its length/number of lines is undetermined.\strut}


}}%

}%

}%

... but it doesn't work. Apparently the inner frame is drawn before 
the outer one. Putting the wider frame inside the narrower results in 
alignment problems --  due to the overfull hbox, I presume.
Your example is of not much use because it can’t be converted to a PDF 
(missing \starttext and empty lines).
Is  there a simple solution in ConTeXt that I haven't found yet, or 
will I have to try some plain TeX box magic myself?

You can use MetaPost to draw the frame/lines for the left and right borders.

\startuseMPgraphic{leftbracket}
z[0] = (EmWidth,OverlayHeight) ;
z[1] = (0,OverlayHeight) ;
z[2] = (0,0) ;
z[3] = (EmWidth,0) ;
draw z[0]--z[1]--z[2]--z[3] withcolor \MPcolor{\overlaylinecolor} ;
\stopuseMPgraphic

\startuseMPgraphic{rightbracket}
z[0] = (-EmWidth,OverlayHeight) ;
z[1] = (0,OverlayHeight) ;
z[2] = (0,0) ;
z[3] = (-EmWidth,0) ;
draw z[0]--z[1]--z[2]--z[3] withcolor \MPcolor{\overlaylinecolor} ;
\stopuseMPgraphic

\installleftframerenderer {bracket}{\useMPgraphic {leftbracket}}
\installrightframerenderer{bracket}{\useMPgraphic{rightbracket}}

\defineframed
  [bracketframed]
  [frame=off,
   offset=1ex,
   leftframe=bracket,
   rightframe=bracket,
   framecolor=red,
   foregroundstyle=\ssx,
   foregroundcolor=darkgray,
   align=normal,
   width=max]

\starttext
\bracketframed{\input knuth }
\stoptext

not now (as it also relates to all kind of other name things like 
preventing a file to load itself as graphic and and i'm not going to 
mess up that code now)

[Procházka Lukáš Ing .]

Hello Hans,

just to remind -
- would it be possible to use "--result=OutputFileName" as the name for the 
output stream immediately?

(See the history bellow.)

Best regards,

Lukas

it's not supported as engine flag


- Suggestion: would it be possible to use "--result=OutputFileName" as
the name for the output stream immediately,
 i.e. not to produce "default PDF file" + rename it to
"OutputFileName" (= --result),
 but to use the "OutputFileName" initially as the output stream?


maybe ... but it has to wait till after tex live code freeze (because it
demands an extra flag to the engine --output-file

so remind me in a month or so
