math typesetting problem in MKIV

math typesetting problem in MKIV

[Brian R. Landy]

Hi, I have a small equation I am attempting to typeset.  Using MKII it  
comes out fine, but under MKIV the text "non-perf. bal." is not  
typeset correctly (non-perf is instead nonperf with the dash under the  
'p', and extra space appears after 'bal.')

\starttext
\math{\text{adjusted  
smm}={{(\text{vTr}+\alpha\times\text{sTr})\times(\text{perf. scheduled  
bal.})+\text{iTr}\times(\text{non||perf. bal.})}\over\text{balance}}}
\stoptext

I just updated minimals to ConTeXt 2009.08.17 10:43 and LuaTeX  
beta-0.42.0-2009071723 and still see the issue.

Thanks,
Brian

It could be an engine problem in the handling of \mathchoice, I
am checking it out. A slightly smaller erroneous file is:


\starttext
\math {(\text{non\discretionary{-}{}{-}perf.})\over1}
\stoptext


more later.

Best wishes,
Taco

Properly fixing this could take me a while, so let me propose
a workaround for the time being. Add this to your preamble and
you should have proper output again:

\unexpanded\def\mathchoice#1#2#3#4%
   {{\ifcase\mathstyle #1\or#1\or#2\or#2\or#3\or#3\or#4\or#4\fi }}

Best wishes,
Taco

Thanks Taco, that worked just fine for me.

Best regards,
