simplefonts: math in headers

[Philipp A.]

[-- Attachment #1.1: Type: text/plain, Size: 584 bytes --]

hi, i have the following setup:

\usemodule[simplefonts]
\setmainfont[Cambria]
\setsansfont[Ubuntu]
\setmonofont[Envy Code R][regularfont=envycoder]
\setmathfont[Cambria]

\setuphead[section][style={\ss\bfb}]

\starttext
\section{Wat? $y=x^2$}
\stoptext

why is the math in the header typeset in computer modern instead of ubuntu
and how do i fix it?

PS: preferrably it should be bold, too. there is a wiki page, “Bold Math in
Section Titles <http://wiki.contextgarden.net/Bold_Math_in_Section_Titles>”
but it doesn’t explain how to do it with simplefonts.

There is no way for me to fix this because it’s a context bug.  You can see the effect with the following example, when you load LM before Pagella the heading use LM Math but when you load Pagella before LM Palatino math is used for the heading.

\setupbodyfont[modern]
\setupbodyfont[pagella]

\setuphead[section][style={\ss\bfb}]

\starttext
\section{Wat? $y=x^2$} $y=x^2$
\stoptext

umm, so this happens because this bug exists and simplefonts sets the fonts
on module load?

is there a way to fix it or is an official fix on the way?

thanks for the info,
philipp

Wait for Hans to fix it and use in the meantime

\usemodule[simplefonts]

\definesimplefonttypeface[mainface][Cambria]
\definesimplefonttypeface[mainface][Ubuntu] [style=sans]
\definesimplefonttypeface[mainface][cambria][style=math]

\setupbodyfont[mainface]

\setuphead[section][style={\ss\bfb}]

\starttext
\section{Wat? $y=x^2$} $y=x^2$
\stoptext

or

\definetypeface[mainface][rm][specserif][Cambria]
\definetypeface[mainface][ss][specsans] [Ubuntu]
\definetypeface[mainface][mm][math]     [cambria]

\setupbodyfont[mainface]

Bold math os somewhat special as we have two variants:

1: a full bold bold math alternartive (only a few math fonts)
2: pseudoboldmath (where we take bold variants in a regular math font)

If you say:

\setfalse\completeboldmathstrategy

at the top of your file then only method (2) is used which is probabkly 
ok for the purpose. This method is actually provides in order to have a 
reasonable bolding in titles even if the font does not provide it. Of 
course bidirectional math adds another axis.

(It reminds me that I need to wrap this up in an article.)

The reason why the double loading fails is that the underlying machinery 
sees a difference between regular (pagella) and bold (still modern) and 
therefore decides that (1) can be applied. I'll try to make this 
heuristic more clever. Another solution (for WS eyes only: add 
\definefontsynonym[MathRomanBold][MathRoman] to the palatino mah 
definition).

ok. fixed. I also added some tracing so that one can see how bold is 
treated (although that bit of code itself was ok):

\enabletrackers[math.families]

i'll upload a beta later today

thanks for the effort. i can’t say i understand anything about fonts if i
judge from what the results of above suggestions look like:

    \usemodule[simplefonts]

    \definesimplefonttypeface[mainface][Cambria]
    \definesimplefonttypeface[mainface][Ubuntu] [style=sans]
    \definesimplefonttypeface[mainface][cambria][style=math]

    \setupbodyfont[mainface]

Well: header math is in unbold cambria, body text in courier or something
like this, and the math font features are not used (tiny parentheses around
matrices, fraction denominators and numerators are shrunk instead of using
small glyphs)

    \setfalse\completeboldmathstrategy

    \usemodule[simplefonts]
    \setmainfont[Cambria]
    \setmathfont[Cambria]
    \setsansfont[Ubuntu]

too slim parentheses, but this is to be expected :D

    \definetypeface[mainface][rm][specserif][Cambria]
    \definetypeface[mainface][ss][specsans] [Ubuntu]
    \definetypeface[mainface][mm][math]     [cambria]

    \setupbodyfont[mainface]

exactly the same as above. slim parentheses in header math, rest working.
cambria in the last line only works when lowercase, but is case-insensitive
in the rm and ss lines. does this solution disable the
completeboldmathstrategy automatically?

thanks for the fixes,
philipp

I’ll upload a new version of the module.

Typescripts and typefaces are case sensitive and \definetypeface[…][…][math][cambria] is not the same as \definetypeface[…][…][math][Cambria].

This method is a core function and unrelated to simplefonts.

It is somewhat .. say that you redefine a typeface in simplefonts and 
use a fontclass name that has already been used, in that case some 
caching starts interfering. I now reset a couple of things before a new 
typeface is defined.
