Re: [NTG-context] About \definefallbackfamily

2016-08-28 Thread Jose Luis Arellano 
Hello list,
I have another question for you, it is about diacritic's replacement
in math mode.

\definefontfamily[mainface][serif][Minion Pro]
\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:lowercaseitalic]
\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:uppercaseitalic]
\definefontfamily[mainface][math][Latin Modern Math]
\setupbodyfont[mainface]

\starttext
{\it Piña}\par
\m{Pi\tilde{n}a}\par
{\it Canción}\par
\m{Canci\acute{o}n}
\stoptext

As you can see, the accents are replaced with Latin Modern Math font.
So, how can i use accents from Minion Pro?

Thanks Wolfgang,

For now, am using this work around to get italic in maths:

\definefallbackfamily[mainface][math][Minion
Pro][tf=style:italic,preset=math:lowercaseitalic]

I have another couple of questions:

1) I am using a font that have the feature onum enabled by default, so
how can i unset this feature for math (lnum,tnum)?
2)  Is there any way to use only some symbols like +, - from Minion
Pro in math mode?

Re: [NTG-context] mathalignment and grid

2016-08-28 Thread Henri Menke 
Dear list,

I did some research in math-ali.mkiv and found that when grid is enabled, the 
whole alignment is simply put in a vbox and snapped to the grid using

\def\math_alignment_snap_start
  {\ifgridsnapping
 \snaptogrid[\v!both]\vbox\bgroup
   \fi}

Unfortunately, the `both` option rounds down both depth and height which is 
inconvenient when the content has large descenders (as in the example).  It  
should be therefore changed to some other grid setting which rounds up.  I 
chose `top` for now but I'm not done experimenting yet.

Cheers, Henri

Re: [NTG-context] \restorecounter ignores first save

Hi Hans,

the save/restore state for the counter in the example is ignored.

 end example


The problem is the check for the table size in the counters.restore
function because after the first save the size of the table is 1:

function counters.restore(name)
local cd = counterdata[name]
if not cd then
report_counters("invalid restore, no counter %a",name)
return
end
local saved = cd.saved
if not saved then
-- is ok
elseif #saved > 1 then


should be > 0


cd.data = remove(saved)
else
report_counters("restore without save for counter %a",name)
end
end

With the latest beta, it looks better, but not perfect (I'd expect the
(1) and the (2) to be aligned). Same input file as in the first email
in this thread gives the attached pdf.

[NTG-context] mathalignment and grid

2016-08-28 Thread Henri Menke 
Dear list,

when I typeset multi line equations using mathalignment and grid the descenders 
of the last line of equation run into the first line of text after that 
equation.  The problem is particularly bad with the Lucida fonts (I think the 
large operators are relatively larger than for Latin Modern).

I could just increase the spacing after equation (commented out in the MWE 
below), but that would introduce an imbalance between space before and space 
after for all equations without descenders.  Furthermore the problem does not 
arise for single line equations with descenders.  Without grid there is also no 
problem.

How do I fix mathalignment to prevent this?

Cheers, Henri
