Hi all,
I am trying to define a start-stop-environment which allows me to
prettyprint MetaPost code and display its results. This is what I
tried:
%%%% code begins here %%%%
\runMPgraphicstrue
\def\PreMPExample{\startbuffer[mpe]}
\def\PostMPExmaple{\stopbuffer%
\startMPgraphic
input mpe.tmp;
\stopMPgraphic
\placeMPgraphic[right]{none}
\expandafter\startMP
\input mpe.tmp
\stopMP
}
\starttext
\stoptext
\startMPExample
draw
for i=0 upto 4:
(50, 0) rotated (i*144) --
endfor
cycle;
\stopMPExample
\stoptext
%%%% code ends here %%%%
and this is what I got:
%%%% messages begin here %%%%
<mpe.tmp>
! Undefined control sequence.
<argument> \def \fontattribute
{\getvalue {\??be MPExample\c!letter }}
\doifdefinedelse ...t \donottest \doprocesstest #2
\fi
\do\dostartattributes ... \fontattribute =\empty }
\doifdefinedelse {#1#3} {\...
<write> ...es {\??be MPExample}\c!letter \c!kleur
{}
<inserted text>
}\endwrite
<argument> ...?be MPExample}\c!letter \c!kleur {}}
...
%%%% messages end here %%%%
Does anybody have an idea what I am doing wrong here? I didn't use the
useMPgraphics constructs in order not to have to worry clashing
temporary file names.
Groetjes
Johannes

Buffers cannot be used in macros (although a workaround is to use
\definebuffer); but, why not use:
\def\startMPExample#1\stopMPExample%
{\startuseMPgraphic{MPExample}#1\stopuseMPgraphic
\placefigure[right]{none}{\useMPgraphic{MPExample}}}
\startMPExample
draw
for i=0 upto 4:
(50, 0) rotated (i*144) --
endfor
cycle;
\stopMPExample
Or simply:
\startuseMPgraphic{MPExample}
draw
for i=0 upto 4:
(50, 0) rotated (i*144) --
endfor
cycle;
\stopuseMPgraphic
\placefigure[right]{none}{\useMPgraphic{MPExample}}

Because I wanted to quote the example, prettyprinted, as well,
and not have to edit the metaposted and the prettyprinted version
in parallel.
Greetings

Right, now you're thinking 'context':
\startbuffer[whow]
your := fance := mpcode ;
\stopbuffer
\typebuffer[whow]
\placefigure{}{\processMPbuffer[whow]}
will be of help then

Ah, stupid me! Yes, I failed to look up \processMPbuffer in the
Metafun manual.

And \definetyping[file][option=MP] does the job for prettyprinting
the \typebuffer'ed text.
Very nice. Thank you
