Support for single string attributes in read #453

Open graziano-giuliani opened 1 month ago

graziano-giuliani commented 1 month ago

Partial modification to allow netCDF Fortran library able to read single string attributes from a netCDF4 CF-1.9 compliant using string type for attributes. It overloads the nf90_get_att_text function returning a single string attribute (note the nlen == 1 in the patch) as if it is a character attributes. What is not implemented are multidimensional strings, and the capability to write string attributes, because of the lack of string type in Fortran standard. This patch would allow reading netCDF files like the one created from the Copernicus cds-beta site for ECMWF ERA5 model. See reference to this in issue #181 "string attributes are not supported yet?"

@graziano-giuliani Is there any chance you could help us by adding a test for this as well?
