Hi people,

I think I saw it somewhere but cannot find it (perhaps I dreamed about
it),

I'm computing ...GR stuff... where f and g are functions of r

var('t,x,y,z,r,theta,phi');
coord = [t,x,y,z,r,theta,phi]
f = function('f', r)
g = function('g', r)

when I compute, the result looks like,

3*D[0](f)(r)^2 + (r^2*e^(2*g(r))*D[0](g)(r) +... et cetera.

Is there any way to configure sage to show the output like,
D[0](f)(r) = f' and so on!!

Thank you!

Dox.
