Thanks for your answer, what shall I use to define non-default
alternatives?

That's easy if one can select the fonts explicitly, but the question
was triggered by the url package which internally switches to math. 

Also in the context example there aren't two font definitions:

\starttext

\font\test= {name:TeX-Gyre-Termes:+onum}
\test 0123456789
$\fam0 \textfont0=\test 0123456789$ 
\stoptext

Nevertheless "\test" seems to use mode=node outside math and
mode=base inside math and I would like to know where the code is
that does it.

I only need to add the layer to do nothing if "=node" is not found, and

Hello,

I'm trying to use the font Minion Pro for my document. I'm using the 
simplefont module but I cannot use the semibold font. I guess I'm 
missing some line in the configuration to bind sb to the semibold variant.
The \definefontfamily command is limited to the default alternatives 
(tf, bf, it, sl, bi, bs ans sc).

Re: [NTG-context] Garamond Premier Pro font goodies file

[Wolfgang Schuster]

mass...@fastwebnet.it 
28. April 2016 um 10:58
Hello list,
I'm using the Adobe Garamond Premier Pro font.
It has 4 optical sizes: Caption, Normal, Subhead, Display.
I tried to modify ebgaramond.lfg to adapt it to Garamond Premier Pro.
You find it as an attachment.

I don't know how to use that goodies file to see the different optical 
sizes

in a document. I've tried this:

\loadfontgoodies[GaramondPremierPro]

\definefontfamily [default] [rm] [tf=name:GaramondPremierPro-Regular,
it=name:GaramondPremierPro-Italic]

\setupbodyfont[default,12pt]

\dostepwiserecurse {6} {22} {1} {
\definebodyfontenvironment[default][#1pt][text=#1pt,em=italic]
}

\starttext

\dostepwiserecurse {6} {22} {1} {
\switchtobodyfont[#1pt]
\purefontname\font: \input tufte
\blank
}

\stoptext

but it does not work. Any help?

%\definefontfamily [default] [rm] [GaramondPremierPro] [opticalsize=yes]
\definefontfamily [default] [rm] [Latin Modern Roman] [opticalsize=yes]

\setupbodyfont[default,12pt]

\starttext

\dostepwiserecurse {6} {22} {1}
  {\switchtobodyfont[#1pt]
   \purefontname\font: \input ward
   \blank}

\stoptext

I will use a better approach as this one does not work
when the thing ends as "at 7.0pt" for example, but in principle
I see I can do surgery on the \fontname and replace there
mode=node if it exists with mode=base.

I only have to figure out the best time to do that
in a context (no pun intended) where people may change
"\mathversion" (latex thing).

Ulrike, thanks a lot for keeping asking questions on this and Philipp
for answering.

I have figured experimentally that I could use (at least in some cases,
and after math fonts are initialized which in LaTeX seems to mean
one needs to enter math mode at least once before)

\font\fixmath=\fontname\textfont\foo mode=base;
\textfont\foo=\fixmath

for example creating this \fontname:

[Vollkorn-Regular]:mode=node;script=latn;language=DFLT;+tlig;+lnum;mode=base;

which is then experimentally observed to obey the second mode specifier
and thus does display lining figures in math mode.

A one would do in Luaotfload: specify base mode when defining the
font. It’s unrelated to math, just the default set of features
that Luaotfload has been applying to every definition for ages.
The reasoning -- by Khaled and others -- was, that the Opentype
standard mandates some defaults so Luaotfload should follow suit.

The defaults can be overridden by setting the appropriate values
in luaotfload.conf(5).

Define two fonts: one for use in math mode, another for where you
really, really require node mode.

[NTG-context] Handling Semi-Bold for Minion Pro in Context (LuaTeX)

[Antoine Cailliau]

Hello,

I'm trying to use the font Minion Pro for my document. I'm using the
simplefont module but I cannot use the semibold font. I guess I'm missing
some line in the configuration to bind sb to the semibold variant. Here is
a short example of my setup:

\definefontalternative[sb]
\definefontalternative[sbi]

\definefontfeature[default][default]
[mode=node,
script=latn,
kern=yes,
palt=yes,
tlig=yes,
trep=yes,
init=yes,
size=yes]
\definefontfeature[frac][default][frac=yes]
\definefontfeature[sups][default][sups=yes]
\definefontfeature[onum][default][onum=yes]
\definefontfeature[lnum][default][lnum=yes]

\definefontfamily [myfamily] [serif] [MinionPro]
\definefontfamily [myfamily] [sans]  [MyriadPro]

\setupbodyfont [myfamily]

\define[1]\sup{\feature[+][f:superscript]#1}
\defineparagraphs[TwoColumns][n=2, align={hz, hanging}]
\setupparagraphs[TwoColumns][1][width=100pt, style=italic, align=left]

\starttext

\startbuffer[Plato]
How you, O Athenians, have been affected by my accusers, I cannot tell;
but I know that they almost made me forget who I was--so persuasively
did they speak; and yet they have hardly uttered a word of truth.
\stopbuffer

\startTwoColumns
Roman\TwoColumns
\getbuffer[Plato]
\stopTwoColumns

\startTwoColumns
Italic\TwoColumns
{\it\getbuffer[Plato]}
\stopTwoColumns

\startTwoColumns
Semi bold\TwoColumns
{\sb\getbuffer[Plato]}
\stopTwoColumns

\startTwoColumns
Bold\TwoColumns
{\bf\getbuffer[Plato]}
\stopTwoColumns

\startTwoColumns
Semi bold italic\TwoColumns
{\sbi\getbuffer[Plato]}
\stopTwoColumns

\startTwoColumns
Bold italic\TwoColumns
{\bi\getbuffer[Plato]}
\stopTwoColumns

\stoptext

Any help is deeply welcome,

Antoine
