Go HEP release 0.6
Release v0.6
is a small iteration (code-wise) but contains:
- a software paper submitted to the Journal of OpenSource Software (JOSS):
- a new
WIP
command, rootio/cmd/root-dump, to dump the content of ROOT files, including the entries of TTrees, - documentation fixes and updates in the
rootio
package, - still more work in the
Delaunay
andVoronoi
area (thanks Bastian!)
One API change that is worth noting, is the retrieval of rootio.Key
s from a rootio.Directory
.
The d4823f0
changes:
type Directory interface {
Get(namecycle string) (Object, bool)
}
to:
type Directory interface {
Get(namecycle string) (Object, error)
}
this allows to more quickly bubble-up errors while reducing boilerplate code at the Directory.Get(...)
