\startMPenvironment : personal font weirdness

\startMPenvironment : personal font weirdness

[David Wooten]

Greetings all,

I've been experimenting with MetaPost/Fun of late. It is indeed fun. In 
trying to have a uniform font in both text and MP areas, however, I am 
running into some difficulty. With a little file like this:

---

\setupcolors[state=start]
\setuppagenumbering[state=stop]

\startMPenvironment [global]
    \usetypescript[palatino][ec]
    \switchtobodyfont[palatino,12pt]
\stopMPenvironment

\starttext

The following example should be very interesting:
\blank

\startuseMPgraphic{very-interesting}

z40 = (2cm,0cm)    ;     z41 = (3cm,0cm) ;
z42 = (3cm,1cm)    ;     z43 = (2cm,1cm) ;
z46 = (2.5cm,.5cm) ;

path F ; F := (z40--z41--z42--z43--cycle) ;

linejoin := mitered ;

drawpath F ;
label("very", z46) ;

\stopuseMPgraphic

\useMPgraphic{very-interesting}

\stoptext

---

everything works very nicely (fonts identical). When I use my own 
typescript file, however:

---

\startMPenvironment [global]
    \usetypescriptfile[minionpro-diss]
    \usetypescript[Minion]
    \switchtobodyfont[Minion,12pt]   
\stopMPenvironment

---

The text appears in the correct font, but the MP section, _while at 
first showing the correct font_, then changes to CM before my eyes. (my 
pdf viewer auto-updates).

Any clues?

Many thanks,
David

hm, looks like a bronwser problem 

what happens if you only include the graphic, 

\startMPpage 
z40 = (2cm,0cm)    ;     z41 = (3cm,0cm) ;
z42 = (3cm,1cm)    ;     z43 = (2cm,1cm) ;
z46 = (2.5cm,.5cm) ;

path F ; F := (z40--z41--z42--z43--cycle) ;

linejoin := mitered ;

drawpath F ;
label("very", z46) ;
\stopMPpage 

so, no other text

Same results, and I also checked with a different viewer. Points to my 
typescript file as a problem, does it? (Which works fine in non-MP 
ConTeXt).

what is the label font then? probably defaultfont so you need to set 
that as well

also, label does not use tex, use

label(\textext("very"),z46)

and friends

That's it, indeed (though without the back-slash for textext):

label(textext("very"),z46)

Many thanks!

should be \textext{very}

I would use
    label(\sometxt{very},z46);

It works much better and you don't need to specify anything in the
MPenvironment. The default document font will be used.

Mojca

To Hans: \textext is not documented anywhere yet. Would it make sense
to make it a synonym for \sometxt perhaps?

Please don't. I have experienced a difference between textext and  
sometext, the former needed when metapost variables are combined.
