MetaPost with etex/btex

MetaPost with etex/btex

[David Munger]

Hello,

The following code results in no label output:

\starttext
\startMPcode
  label.top(btex Some label etex, (1cm,1cm)) ;
\stopMPcode
\stoptext

I'm using ConTeXt 2003.12.12.


By the way, why don't \startMPgraphic and \stopMPgraphic do anything?

Hi David,

The use of the different possibilities of including metapost graphics in 
ConTeXt are described in the METAFUN-manual on pages  9,  81-82, 115

For your refernce I attach a small demo file using your code ...

Kind regards Willi

Hi Willi,

Thanks for the examples, they'll sure be useful. But I realize I have not been  
precise enough in my post. The point is that

\startMPcode
  fill fullcircle scaled 1cm withcolor red ;
\stopMPcode

works, while

\startMPcode
  label.top("Some label", (1cm,1cm)) ;
\stopMPcode

produces some garbage between "Some" and "label", and

\startMPcode
  label.top(btex Some label etex, (1cm,1cm)) ;
\stopMPcode

doesn't work at all.

Sorry for being that vague.


David

Hi David,

> Sorry for being that vague.

You are still very vague. Your posted example works fine here. Please
report what ConTeXt/texexec version you have. You might think of
posting your logfile. 

Do you have \protectbufferstrue in cont-sys.tex?

That was the exact point. It fixed it. Thanks a lot!

Hi,

what ConTeXt version do you have? It sounds like an older one.

texexec says:
ConTeXt  ver: 2003.12.12  fmt: 2003.12.14  int: english  mes: english

Freshly downloaded, but poorly installed by a novice... Actually I replaced  
the ConTeXt part from the debian unstable package source. So teTeX and ConTeXt  
are not synchronized.

Hmmm,...

I haven't tried this sort of thing for a while, so I downloaded the new
beta into my Miktex system, regenerated formats, and attempted to compile
the code below. I got the following error:

! Undefined control sequence.
l.1 \global \loadfontfileoncetrue
                                 %
! You can't use a prefix with `\shipout'.
<to be read again>
                   \shipout
l.2 \shipout
            \hbox{\smash{\hbox{\hbox{% line 226 C:\temp\junk-mpgraph.mp
[1] )
(see the transcript file for additional information)

I have write18 enabled in miktex.ini, and adjusted cont-sys.tex:

% Enabling run time \METAPOST\ (also enable \write18 in 
% texmf.cnf):

\runMPgraphicstrue 
\runMPTEXgraphicstrue

% This saves some runtime, but needs a format, which you can
% make with 'texexec --make --alone metafun'. Make sure that 
% the mem files are moved to the used web2c path (locate with 
% 'kpsewhich plain.mem').

\useMETAFUNformattrue

% Enabling nested pretty printing:

\newprettytrue 

% This can be a way to get things working on system with 
% name clashes. (Some \TeX's tend do search system wide.)

\protectbufferstrue

Anyone have an idea what I am doing wrong?
