math font

Instead of the mathfont'a italics I would like to try an upright typeface. See for example the P.p on the left of the sample, 1-p in the second \pmatrix and the toprow in the last one.

How can I do this globally, there by avoiding avoiding the need to sprinkle \mathrm's all around as in: \pmatrix{\mathrm  p\cr\mathrm 1-p\cr}. A single \mathrm in front as not enough for the matrices.

By the way, this comes from the lucida typescript.

I don't think that there is a global interface. You can try

\appendtoks \mathrm \to \everysetupmathematics.

In principle, we can have an interface similar to 
\setupmathematics[lcgreek=...,ucgreek=...], but the choice of keys 
requires some thought.

That is because \pmatrix uses \halign, where each cell starts a new math 
gruop. This reminds me of an old request to have support for \mhalign and 
\mvalign at the engine level.

just give a functional description and put it in the luatex tracker

math font

[Thomas A. Schmitz]

Hi all, 

in my environment file, I have defined a math font:

\definefontfamily [thomas] [math]  [XITS Math]

and as far as I can see in the log file, this font is found:

system          >    9: filename=xits-math.lfg filetype=tex foundname=/Users/lmtx/tex/texmf-context/tex/context/fonts/mkiv/xits-math.lfg fullname=/Users/lmtx/tex/texmf-context/tex/context/fonts/mkiv/xits-math.lfg usedmethod=database

system          >   14: filename=XITSMath-Regular.otf filetype=otf format=otf foundname=/Users/lmtx/tex/texmf/fonts/opentype/public/xits/XITSMath-Regular.otf fullname=/Users/lmtx/tex/texmf/fonts/opentype/public/xits/XITSMath-Regular.otf usedmethod=database

mkiv lua stats  > loaded fonts: 16 files: texgyretermes-bold.otf, texgyretermes-italic.otf, texgyretermes-regular.otf, xitsmath-regular.otf, dejavusansmono.ttf, gentiumalt-i.ttf, gentiumalt-r.ttf, myriadpro-it.otf, myriadpro-regular.otf, kadmosu.otf, monotype  - timesnrmtpro-bold.otf, monotype  - timesnrmtpro-italic.otf, monotype  - timesnrmtpro.otf, timesbold.ttf, timesitalic.ttf, times-roman.ttf

nevertheless, on the terminal and in the log file, I get dozens of lines with this message

fonts           > math: unset for global bodyfont thomas at 11pt

This is with the latest 2020.01.26 19:19. I have a slight suspicion that this behavior is new, but I’m not totally sure. It’s just a small nuisance, but something is wrong here, I would say?

All best

Thomas

Does this also happen when you use \definetypeface to set the math font?

\definetypeface [thomas] [mm] [math] [xits] [default]

No, with this change, the warnings are gone. New syntax? Or user error?

I bet on user error.

We always need a math font because the math machinery has to be set up 
and context will kick in a fallback font when none has been set but that 
is done as last resort when \starttext happens. When this is done 
locally you will get the warnings. When you get a real error (abort), 
you probably have some content before fonts are set up.
