  The Bondi solution, which describes the radial inflow of a gas onto a
non-rotating black hole, provides a powerful test for numerical relativistic
codes. However, the Bondi solution is usually derived in Schwarzschild
coordinates, which are not well suited for dynamical spacetime evolutions.
Instead, many current numerical relativistic codes adopt moving-puncture
coordinates, which render black holes in trumpet geometries. Here we transform
the Bondi solution into trumpet coordinates, which result in regular
expressions for the fluid flow extending into the black-hole interior. We also
evolve these solutions numerically and demonstrate their usefulness for testing
and calibrating numerical codes.
