Hi all,
I've been trying to use the \overrightarrow command within a metapost graphic,
but it doesn't work. Math mode does work, for example \vec works like
expected. Outside of metapost, \overrightarrow works as expected.
This seems to broken for extensible math arrows like \xrightarrow as well.
\let\normaloverrightarrow\overrightarrow
\unexpanded\def\overrightarrow{\normaloverrightarrow}
And this fix helps there as well. Could this perhaps be fixed in general for
all extensible arrows?
Have you tried the new current yet? There was a whole bunch of extra
\unexpanded-s in it already.
Best wishes,
Taco
