Opentype features and space after comma in math mode

Opentype features and space after comma in math mode

[Jose Luis Arellano]

Hello list,
Two questions:

1) How can i enable opentype features (onum, lnum, tnum) in math mode?
2) How can i avoid the space after comma in math mode?

I tried this without success:

\definefontfeature[default][default][onum=yes,lnum=no,tnum=no]
\definefontfeature[lnum][default][onum=yes,lnum=no,tnum=no,mode=base]
\definefontfamily[mainface][serif][TeX Gyre Pagella]
\definefontfamily[mainface][math][TeX Gyre Pagella Math][features=lnum]
\setupbodyfont[mainface]

\starttext
1,123\par
\m{1,123}\par
\stoptext

Thanks in advance...

Re: Opentype features and space after comma in math mode

[Jose Luis Arellano]

After some research, i founded (in Wiki) that space after a comma can
be avoided using: \setupmathematics[autopunctuation=all]. Sorry for
that.

So, only left second question. This is about opentype features,
specifically tabular numbers in math mode. This issue (i think) is
related to the commercial font that am using, because it have some OT
features enabled by default (eg: onum=yes, tnum=no and lnum=no).
Curious is that i can only set lnum and onum but not tnum in math.

Do you use Minion Math?

Does this work (untested)?

\definefontfamily[inlinemath][mode=base,lnum=yes] % tnum=yes etc.

\definefontfamily[…][mm][…][tf=features:inlinemath]

BTW: You can list all features of a font with "mtxrun --script fonts 
--list --info <fontname>".

No, am using another commercial font (Fedra Serif B Pro) without math
support and \definefallbackfamily.

No.
This is what am using:

\definefontfeature[default][default][tnum=yes,lnum=yes]
\definefontfeature[mathdigits][default][mode=base,tnum=yes,lnum=yes]
\definefontfamily[mainface][serif][...]
\definefallbackfamily[mainface][math][...][preset=math:digitsnormal,features=mathdigits]
\definefontfamily[mainface][math][DejaVu Math]
\setupbodyfont[mainface,10pt]

\starttext
0123456789\par
\m{0123456789}
\stoptext

You can see the result in the attached PDF.

You last example was misleading because you tried to change the features 
of the math font.

I can reproduce it with one of my fonts but have no solution for it.

Dear Wolfgang.

In recents versions of Context, what is the correct way to use lnum feature
in maths?

This doesn't works anymore:

\definefontfeature[mathdigits][default][mode=base,tnum=yes,lnum=yes]
\definefallbackfamily[mainface][math][...][preset=math:digitsnormal,features
=mathdigits]

Thanks in advance.

José Luis,

I think that line should read:

    \definefontfeature[mathdigits][mode=base,tnum=yes,lnum=yes]

But without a sample, I’m afraid I cannot test it.

Just in case it might help,

Pablo

most math setups have an (unset) mathextra featureset that you can use 
for such extra features and indeed one should not inherit from defult

   \definefontfeature[mathdigits][tnum=yes,lnum=yes]

of course it also depends on what a font provides (if we're talking 
alternates one can also use the normal 'alternates' feature switching in 
math)

Thanks guys, but unfortunately the code provided doesn't works.

\definefontfeature[mathdigits][mode=base,tnum=yes,lnum=yes]
\definefontfeature[mathdigits][tnum=yes,lnum=yes]

José Luis,

could you provide a minimal complete sample that shows the issue?
