A change in textext Metafun maco?

A change in textext Metafun maco?

[Michal Kvasnicka]

Good noon.

I have updated to the new ConTeXt and some of my documents failed to work. I 
use the FunnyFrame example from the Metafun manual. With the old ConTeXt all 
worked well. Now I can see in the title of a frame just "unknown". I played a 
little with the mpgraph.mp and I suspect the macro textext not to work well. 
Or in the same way as before. Where can be a bug? (Well, I updated only TeX, 
Metapost, and Perl part of ConTeXt and generated formats -- I didn't updated 
the ConTeXt stuff for plain or for LaTeX).

Can you help me? Many thanks.

the metapost code moved one level down the metapost tree, are you sure that 
you use the right mp code (deleted th eold code):

see: /metapost/context/...

otherwise, a small failing example may help to nail down the problem

Good evening.

I can't find the reason of the bug. So I send a minimal test file. The problem 
is, that the frame has title "unkonwn", not "Example" as I expected. Many 
thanks for your help.

Sorry that this won't help you but: it works fine here. teTeX 2.0.2,
newest ConTeXt beta.

I remember having problems with textext too, but running texexec a
second time did work for me. 

And, of course, make sure you have \protectbufferstrue set in a) your
cont-sys.tex or b) in your testfile. I bet that this is the reason
for the bug.



Any suspicious lines in the logfile?  This is what mine looks like.

running texexec twice cannot be the solution, since one run of texexec
needs already much time.
In the last weeks i had also often problems with text in MP graphics.
Now, after an update to the current beta yesterday, these problems are
gone.

Good evening.

> \protectbufferstrue

Well, this is a solution. What's that? Was it set differently in the older 
ConTeXt, or I'm stupid and deleted some of my old configuration files? Hm. 
Many thanks anyway.

M.K.

I don't know. It names some of the files differently. It was one of
my first prolems with ConTeXt (with the same graph as yours :)

Well, I would not dare to say you are stupid :) Usually this is
set in cont-sys.tex which is distributed as cont-sys.ori. Perhaps you
have deleted this file? 

I don't know if this is documented anywhere. I could not find it in
the metafun manual.
