ghosts in mpost?

ghosts in mpost?

[Olivier]

Hi everyone,

I ran into trouble while trying to compile 

\startreusableMPgraphic{try}
  label(textext{$x\vphantom{y}z$}, origin);
\stopreusableMPgraphic

\reuseMPgraphic{try}

Is this a bug?

Olivier

Well, the error message is not nice, and maybe
an \unexpanded in front of the definition of
\vphantom would be nice, but your example is
missing the \ in front of textext.

Best wishes,
Taco

You're right, it works much better :D


However, my original concern was that the following
does not seem to work either:

\startreusableMPgraphic{try}
  label(btex {$x\vphantom{y}z$} etex, origin);
\stopreusableMPgraphic

\reuseMPgraphic{try}


Anyway, since -> \textext is the way to go...

Many thanks for the quick solution!
Olivier
