How to best write objects to TFile or TDirectory? ROOT has the concept of a current working directory, creating tons of confusion. I would propose not to deal with that part of the API at all (i.e. TObject::SetDirectory, TDirectory::Add), but rather make a sane version of it.
h5write("/tmp/test2.h5", "mygroup2/A", A)
#or
h5open("mydata.h5", "w") do file
write(file, "A", A) # alternatively, say "@write file A"
end
#or
using HDF5
h5open("test.h5", "w") do file
g = g_create(file, "mygroup") # create a group
g["dset1"] = 3.2 # create a scalar dataset inside the group
attrs(g)["Description"] = "This group contains only a single dataset" # an attribute
end
