Font selection ranges

Font selection ranges

[Hans Aberg]

I want to define an environment for computer code including non-ASCII characters, using Xits or STIXGeneral except in the ASCII range, where some monospace font like Courier should be used.

If I do:
\setupbodyfont[xits,10pt]
\definetyping[code]
\setuptyping[code][margin=yes]

\starttext
  \startcode
 for ∀i, j ∈ I
   do a(i, j) ≔ b(i, j)
  \stopcode
\stoptext

Then the math characters won't show. They will show using
  \setuptyping[code][style=normal,margin=yes]
but then the ASCII range isn't monospace.

In LaTeX, one can use \setmathfont[range={"0001-...,}] to set ranges for fonts, but I could not find that for ConTeXt.

Hans

It's not a solution of your problem, but this work

\setupbodyfont[dejavu]
\definetyping[code]
\setuptyping[code][margin=yes]

\starttext
 \startcode
 for ∀ i,j ∈ I
  do a(i,j) ≔ b(i,j)
 \stopcode
\stoptext

You can use the lines environment when you don’t need syntax highlighting: 

\setupbodyfont[xits,10pt]

\definelines
  [code]
  [space=yes,
   style=mono,
   before=\startnarrower,
   after=\stopnarrower]

\starttext \showframe

\startcode
for $∀$i, j $∈$ I
  do a(i, j) $≔$ b(i, j)
\stopcode

\stoptext

You can use the fallback feature, but then you've to define your own
typescripts, see font-col.mkiv for examples.
