Bug ?!? \protectbufferstrue

Bug ?!? \protectbufferstrue

[Patrick Gundlach]

Hi,

it seems that a missing \protectbufferstrue causes a lot of 
malfunctioning. It happened to at least three people I know of 
:-) It might be worth (?) looking closer at this.

Viele Gruesse,

Indeed, so what exactly is the problem; mpgraph.mp is file that makes 
troubles, and it happens that there can be a mpgraph.mp on a full tex 
system. This means that teh [often unfortunate default global] search of 
kpse finds the wrong file. This is why i make a dummy always as well as 
test for the length. Now, the first question to answer is: does it happen 
in the latest context?

Hi,

the file:

\protectbuffersfalse
\setupcolors[state=start]
\startuseMPgraphic{Kreis}
  fill fullcircle scaled 200pt withcolor .625yellow ;
\stopuseMPgraphic
\useMPgraphic{Kreis}
\stoptext

the release:

This is pdfeTeX, Version 3.14159-14h-released-20010417-2.1 (Web2C 7.3.3.1)
entering extended mode
ConTeXt  ver: 2001.7.11  fmt: 2001.7.16  int: english  mes: english

File cont-sys.tex:

%   \runMPgraphicstrue 
%\runMPTEXgraphicstrue
  \recycleMPslotstrue 
\useMETAFUNformattrue
\protectbufferstrue

texexec --automprun mptest.tex
and 
texexec mptest.tex

both don't show the circle (instead a square with the error 
message name: dummy file:mpgraph.1 unknown)

but if I comment out the \protectbufferfalse (so make 
\protectbuffertrue because of cont-sys)
the circle shows up.

Viele Gruesse,

Maybe this helps (in texexec)

  sub MPJobName
   { my $JobName = shift ;
     my $MPfile = shift ;
     my $MPJobName = '' ;
     if (-s "$JobName-$MPfile.mp">100)
       { $MPJobName = "$JobName-$MPfile.mp" }
     elsif (-s "$MPfile.mp">100)
       { $MPJobName = "$MPfile.mp" }
     else
       { $MPJobName = "" }
     return $MPJobName }

don't forget to add teh \starttext -)

Hans

PS. Before testing, say:

texutil --purge

Hello out there (I am just eating an apple from the netherlands

It does help! Circle shows up.

\protectbuffersfalse
\setupcolors[state=start]
\starttext
\startuseMPgraphic{Kreis}
  fill fullcircle scaled 200pt withcolor .625yellow ;
\stopuseMPgraphic
\useMPgraphic{Kreis}
\stoptext

yes, ... I was confused by some error msg. But now its away 
(b/e error)

I have removed all files except the mptest.tex (Just tried the 
purge cmd - looks nice. I have written a small norton commander 
like clone for emacs just to remove all files except the *tex 
files, because context is flooding my dirs. )

when a file has b/e errors texexec/util will kind of quit (to be sure),

actually, the mp stuff and buffers may flood the system, but context itself 
only needs the tui.tuo
