Hi all,

I am trying to do the following in Metapost but my new math symbol  is 
not recognized.
Context knows about it but Tex does not.

How can I make this work ?

Kind regards
Wim Neimeijer

% ================= Test code ========================
\loadmapfile[original-youngryu-tx.map]
\definebodyfont [28pt,24pt,18pt,
  17.3pt,14.4pt,12pt,11pt,10pt,9pt,8pt,7pt,6pt,5pt,4pt] [mm] [
  mc=txexa sa 1]

\setupbodyfont [11pt]
\definemathsymbol [varointctrclockwise] [op] [mc] ["2B] [mc] ["2C]

\starttext
\startformula
\varointctrclockwise_{\gamma} f(z) \: dz = 0
\stopformula
\startMPcode
    picture p ;
    path q;
    numeric u;

    u := 1cm;

    p := btex $\varointctrclockwise_{\gamma} f(z) \: dz = 0$ etex;
    p := p scaled 0.15cm;
    draw p;
\stopMPcode
\stoptext
  
    

make sure that mp knows about the definitions: 

- first extend the math collection (use decimen, since there is a linesplit bug with " here) 
  

- then load the times font 
- somehow display and inline math render differently; something for taco 

\startMPenvironment[global]

    \startmathcollection [default]
        \definemathsymbol [varointctrclockwise] [op] [mc] [43] [mc] [44]
    \stopmathcollection
    \usetypescript[times][ec]
    \setupbodyfont[times,11pt]

\stopMPenvironment

\starttext

why the funny .15cm scale ... 
  

\startformula
    \varointctrclockwise_{\gamma} f(z) \: dz = 0
\stopformula

$\varointctrclockwise_{\gamma} f(z) \: dz = 0$

\startMPcode
    draw btex $\varointctrclockwise_{\gamma} f(z) \: dz = 0$ etex scaled 0.15cm ;
\stopMPcode

\startMPcode
    draw btex $\displaystyle \varointctrclockwise_{\gamma} f(z) \: dz = 0$ etex scaled 0.15cm ;
\stopMPcode

\stoptext
