luatex-plain & metapost

luatex-plain & metapost

[luigi scarso]

I'm experimenting with
luatex-plain in minimals, cfr.
minimals/tex/texmf-context/tex/generic/context

All examples are compiled with

$> luatex  --fmt=luatex-plain.fmt luatex-test.tex

luatex-plain.fmt is build with

$>luatex --ini luatex-plain.tex


This is ok:
%luatex-test.tex
\pdfoutput=1
\setmplibformat{metafun}
\mplibcode
    beginfig(1) ;
        draw fullcircle
            scaled 10cm
            withcolor red
            withpen pencircle xscaled 4mm yscaled 2mm rotated 30 ;
        label("Foo",(0bp,0bp));
    endfig ;
\endmplibcode
\end

This is wrong:
%luatex-test-wrong.tex
\pdfoutput=1
\setmplibformat{metafun}
\mplibcode
    beginfig(1) ;
        draw fullcircle
            scaled 10cm
            withcolor red
            withpen pencircle xscaled 4mm yscaled 2mm rotated 30 ;
        label(textext("Foo"),(0bp,0bp));
    endfig ;
\endmplibcode
\end

Any ideas ?

textext is a mkiv feature

not a metafun macro ?

Anyway, this also doesn't work
%luatex-test-wrong.tex
\pdfoutput=1
\setmplibformat{metafun}
\mplibcode
   beginfig(1) ;
       draw fullcircle
           scaled 10cm
           withcolor red
           withpen pencircle xscaled 4mm yscaled 2mm rotated 30 ;
       label(btex Foo etex,(0bp,0bp));
   endfig ;
\endmplibcode
\end

forget about metafun in plain ... it cooperates with mkiv and it's very 
unlikely that i'll ever make it generic

There is no btex .. etex in mplib, at all.

So there are no others way to put a text in a btex ...etex fashion ?

Not without macro/lua support, no. context mkiv does support these
things, but Hans is (understandably) unwilling to write code to
deal with the fairly unpredictable font setup of the luatex-plain
environment.

Best wishes,
Taco

OK -- I understand this.
Any plan to implement btex...etex in mplib ?

well, you can set up some kind of mechanism that eventually produces a 
picture that mp can handle, or roll out your own code

anyhow, i see not much reason for spending time on that kind of support 
for plain as i have no use for it

Not btex ... etex, no.

Maybe something new will appear in the long run, maybe not.

Well... I have implemented btex .. etex feature
upon Hans & Taco's luatex-mplib.* files
mostly by mimicking the implementation in context.

Please visit
