[Tex/LaTex] MinionPro, including math, in ConTeXt

contextfontsmath-mode

A rather simple question, which probably will have a complex answer. I'm trying to migrate to ConTeXt, since I want to have a layout not easily achieved with LaTeX (grid…). In LaTeX, MinionPro is working fine, including the math, after some voodoo and lots of hair pulling. I haven't touched it since. Now, how to get this stuff to work in ConTeXt as well? I started with the body font, that's the easy part. I have no clue where to look for the math font, or how to port/translate the TeX stuff I have to something ConTeXt will understand. Where do I begin?

Edit: To clarify, what I currently have is

\starttypescript [serif] [minionpro]
    \definefontsynonym [Serif] [name:minionproregular] [features=default]
\stoptypescript

\starttypescript [minionpro]
    \definetypeface [minionpro] [rm] [serif] [minionpro] [default]
    \definetypeface [minionpro] [mm] [math] [minionpro] [default]
\stoptypescript

\usetypescript [minionpro]
\setupbodyfont [minionpro,10pt]

\starttext
Hi, this is text. A formula: $x + y = z$.
\stoptext

This is obviously not enough information to make it go, it helpfully cries out with the error

error on line 14 in file tmp.tex: Math error: parameter \Umathquad\displaystyle is not set ...

To use the Minion fonts in ConTeXt:

Make sure that you have the fonts. Running

mtxrun --script fonts --list --pattern="*minion*" --all

should give you:

minionpro             minionprobold      MinionPro-Bold.otf
minionprobold         minionprobold      MinionPro-Bold.otf
minionproboldit       minionproboldit    MinionPro-BoldIt.otf
minionprobolditalic   minionproboldit    MinionPro-BoldIt.otf
minionproit           minionproit        MinionPro-It.otf
minionproitalic       minionproit        MinionPro-It.otf
minionpronormal       minionproit        MinionPro-It.otf
minionproregular      minionproregular   MinionPro-Regular.otf

The Minion fonts do not come with a accompanying math fonts. However, for simple math you can use symbols from a different math font (e.g., Pagella Math), and use letters and digits from Minion. To do so, you need a recent (2013.12.20 or newer) version of ConTeXt. Then use the following test file:

\definefontfamily [mainface] [rm] [Minion Pro]

\definefallbackfamily [mainface] [math] [Minion Pro] [math:lowercaseitalic] [force=yes]
\definefallbackfamily [mainface] [math] [Minion Pro] [math:digitsnormal]    [force=yes]
\definefontfamily     [mainface] [math] [TeX Gyre Pagella Math]

\setupbodyfont[mainface]

\starttext
\input ward

\startformula
  c^2 = a^2 + b^2
\stopformula

\stoptext

which gives:

[Tex/LaTex] Ampersand in math in ConTeXt

By default there is no such command in math mode. However, you can switch to text mode where \& is available:

\starttext
  \startformula
    A \text{\&} B
  \stopformula
\stoptext

If you use \asciimode you don't even need the backslash:

\asciimode
\starttext
  \startformula
    A \text{&} B
  \stopformula
\stoptext

To avoid wrapping the ampersand in \text add the following code to your document. It redefines \& for both, inline and display math.

\appendtoks
  \def\&{\text{\letterampersand}}
\to\everymathematics

\starttext
  \startformula
    A \& B
  \stopformula

  \math{C \& D}

\stoptext

[Tex/LaTex] More Math Fonts in ConTeXt

Here is a complete example on how to use Euler.

Download Euler OTF from Github
Move the font somewhere in your $TEXMF/fonts/opentype tree. To see the list of folders that ConTeXt searches, run:
```
mtxrun --expand-var=TEXMF
```
or
```
mtxrun --expand-var=TEXMFHOME
```
Update the font database by running
```
mtxrun --script font --reload --force
```
Check that ConTeXt can find the fonts:
```
mtxrun --script fonts  --list --pattern=euler --all
```
(you should see euler.otf in the list).

Compile the following example file (this needs ConTeXt version from October, 2013 or later).

\usetypescriptfile[euler]

\definetypeface[mainface][rm][serif][palatino]         [default]
\definetypeface[mainface][ss][sans] [helvetica]        [default] [rscale=auto]
\definetypeface[mainface][mm][math] [pagellaovereuler] [default] [rscale=auto]

\setupbodyfont[mainface,12pt]

\appendtoks \rm \to \everymathematics
\setupmathematics
  [lcgreek=normal, ucgreek=normal]

\starttext

\startformula
   {\Bbb P}(x) = \sum_{i=1}^n α_i x^i
\stopformula

\stoptext

I get the following output:

Note that Euler opentype font is not complete. The pagellaovereuler typescript loads Pagella as a fallback font, so the missing symbols (like the blackboard bold P in the above example) are taken from Pagella.
