Replying to lucadelu:
Please look and try r74438
Thanks, but now I get
r.plane output=plane dip=45 azimuth=9 easting=0:04:14.5E northing=48:52:14.5N elev=1000 type=CELL
ERROR: Input coordinates seems to be invalid
With debug output added locally, I see that "E" and "N" are the problem (which are accepted in g.region, see https://grass.osgeo.org/grass76/manuals/g.region.html#changing-extent-and-raster-resolution-using-values):
r.plane output=plane dip=45 azimuth=9 easting="00:04:14.5E" northing="48:52:14.5N" elev=1000 type=CELL

IMHO float_or_dms() needs an update to accept E and N.
