I don't understand the fix, but it gives the correct output.


hm, given your involvement in math you should study it -)

it boils down to the fact that in luatex we can actually ask what the 
upcoming style can be (text, script, scriptscript)


normally a choice means 4 times processing and tex will use one only, 
while in this case i could write \text in a way that processes only once 
(so, way faster as we only have 1 bodyfont switch now)

Actually, the bug is with \setcurrentfontbody

\starttext
ABC \hbox{\setcurrentfontbody{\scriptscriptface} Testing} DEF
\stoptext

The above works correctly in mkii but not in mkiv. I really don't
understand what \setcurrentfontbody is supposed to do. In Mkii it scales
the bodyfont if \scriptface or \scriptscriptface is used as an argument;
but does not work for any other value (e.g. \setcurrentfontbody{20pt}).
In MkIV it does not do anything.


How about:

\unprotect

\ifdefined\font_basics_switchtobodyfont\else
\def\font_basics_switchtobodyfont#1{\switchtobodyfont[#1]}%
\fi

\def\mathstyleface#1% #1 is number (\normalmathstyle)
  {\ifcase#1\relax
 \textface \or
 \textface \or
 \textface \or
 \textface \or
 \scriptface   \or
 \scriptface   \or
 \scriptscriptface \or
 \scriptscriptface \else
 \textface
   \fi}

% For some reason mathfaces are not normalized .. why not?

\protect

\setupbodyfont[dejavu]

\starttext

\testfeatureonce{1000}{$f_{\text{text $a+b$}_{\text{text 
$a+b$}_{\text{text $a+b$$\par} % 2.7


\stoptext




There is also a bug in the definition of \text in mkii. In

ok, fixed,

There is another bug with \text.

{\switchtobodyfont[sans] $\text{sans}$}

does not switch to sans font. Both the incorrect scaling and wrong font 
switch can be corrected by restoring the old definition of \text in 
math-ini.mkiv. Based on the comments in that file, this will come at a 
high penalty on speed. (Slow but correct is better than fast but wrong!)

Notice \scriptsctlye and \scriptscriptstyle instead of \textstyle in the

definition in MkIV also needs to be changed in a similar manner.

[NTG-context] math: \text does not scale properly

Hi there,

As Aditya mentioned in a former posting (*) that \text{ ... } should scale 
properly when used as super- or subscript, I have prepared a minimal example to 
demonstrate that it doesn't. In my document I have switched from \text{ } to 
\normal, which works.

Kind regards,
Andreas

Re: [NTG-context] math: \text does not scale properly

2012-10-04 Thread Andreas Mang
Hi Alan,

thanks for your help. That's indeed an option, but not much of a difference to 
using \normal I suppose.

In addition, \text has the nice feature of preserving the space character, 
which makes it very useful for lazy people (of course I can add \, and 
friends but...).

Cheers,
Andreas
