Re: [metafont] context/metafun problem

[Denis B. Roegel]

I got the example to work, by calling cont-en and mpost
explicitely. Somehow, my texexec has trouble processing it. 

Continuing my experiments, I wanted to try positional graphics.
Here is my input file, adapted from the metafun documentation:

\starttext

\startMPpositiongraphic{mypos:line}
  path pa, pb, pab ; numeric na, nb;
  initialize_box(\MPpos{\MPvar{from}});
  na := nxy ; pa := llxy..lrxy..urxy..ulxy..cycle ;
  initialize_box(\MPpos{\MPvar{to}});
  nb := nxy ; pb := llxy..lrxy..urxy..ulxy..cycle ;
  if na=nb :
    pab := center pa -- center pb ;
    pab := pab cutbefore (pab intersectionpoint pa) ;
    pab := pab cutafter (pab intersectionpoint pb) ;
    pickup pencircle scaled 1pt;
    draw pab withcolor .625yellow;
    anchor_box(\MPanchor{\MPvar{from}});
  fi;
\stopMPpositiongraphic

\setMPpositiongraphic{X-1}{mypos:line}{to=X-2}
\setMPpositiongraphic{X-2}{mypos:line}{to=X-3}

In a previous section we saw that some \hpos {X-1} {words} were
\hpos {X-2} {circled} and connected by an \hpos {X-3} {arrow}.
As with most things in \CONTEXT, marking these words is separated
from declaring what to do with those words. 

\stoptext

The file compiles with cont-en, and the mpgraph file compiles
with mpost, but I get a lot of "special" errors when I try
to produce the PostScript file. Does this example work with
a PostScript output?

Thanks,

Denis

It does here, but that is because I have the dvi postprocessing script -) 

If you really are in despair and cannot use pdftex, i can see if i can
collect the perl files needed, but I prefer to wait till the binary is
svailable (berend will look into it, since there is a dvi library/presented
at tug2000). The specials you see contain positional info that is to be
filtered from the dvi and fed back into tex. Works pretty good btw, but
slower than pdftex.

I can use it, but I was just wondering. So, I added \pdfoutput=1
at the start of the file, and here is what I get:

I keep getting these "Non-PDF special ignored!" messages, even after
mposting the mpgraph file and calling again cont-en.

Never switch the output that way, either say: 

texexec --pdf 

or add 

% output=pdftex 

or add 

\setupoutput[pdftex]

since context (like any tex package) needs to set up its drivers (special
drivers) to match the postprocessor, here being pdftex. IN general: never
use any low level \pdf... !

Ok. Now, I run into a problem I already had (of course!) with texexec:
