Metapost/Metafun/Tex/Context question

[WN]

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

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

Math family mc has to be txexa or something similar before the code
actually shows the integral instead  of a plus sign, but Wim can
figure that out himself, no doubt  :-)

That is normal. One is with an operator with \limits, one without.

Hans and Taco have already explained the correct way to do this, so I 
will not go into that. This is one place where you can use the new 
sometxt feature.

Replace this by

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

and everything works!

I was wondering about the \sometxt feature, I did not know exactly how 
to use it, but will certainly do
some experiments. Thanks Wim.
