What an interesting coincidence, that makes at least three of us. Apparently it's an idea whose time has come.
Mine is also an incomplete low-level binding but is currently under semi-active development and I aim to make it cover the entire hdf5.h interface.
If anyone is interested in it I've put it on github at: https://github.com/mokus0/bindings-hdf5
Hi, This is fairly extensive indeed! I got nowhere near this, but also took a somewhat different angle, especially by using StorableArrays for passing arrays around (I used HDF5 in conjunction with LaPack). I also experienced with going a little higher level here and there. Attributes aren't implemented yet, because that would require making location ids a type class. An unsolved problem is the safe representation of ranks: I went for generality by using lists for indexing, but it would be nice to express dimensionality constraints in the types (with sane syntax). Maybe there's a handy technique for this, I didn't explore the field. Talking about indexing, choosing Fortran convention seems to be a mistake in retrospect, but that's no big deal. I attach my code so you can get a better idea what I'm talking about, maybe you can find some usable pieces. Separating the generic hid type into specific newtypes worked out to some extent, but maybe isn't a good idea at the lowest level (where the FFI makes it automatic). I'd need broader experience with the HDF5 API to tell. -- Regards, Feri.
