I don’t know if there will be an API/ABI-compatible Open Babel 2.2  
release. Certainly I’d really love to break some things this summer  
(atom indexing at the top of the list).

If you have some “Open Babel Enhancement Proposals,” it seems like  
Noel already got started:  
[http://openbabel.sourceforge.net/wiki/OBEP\_1](http://openbabel.sourceforge.net/wiki/OBEP_1)

One reason I wanted to try Avogadro is that I knew we’d be exercising  
Open Babel in new and exiting (i.e., buggy) ways. So far, so good. 🙂

Cheers,

Geoff,

Is OB trying to maintain ABI compatability? If not, I would suggest  
possibly adding three new functions to OB (eventually) ::NewAtom(OBAtom  
&atom), ::NewBond(OBBond &bond)… etc so that we can copy stuff over  
in a subclass (this would be a good solution for the problem you  
implemented with selecting the newly pasted atoms).

Another solution might be that we add a flag in the primitive class  
“selectNew” that does the selection in the NewAtom function rather than  
in +=. That way in Molecule::operator+= we can setSelectNew(true) and  
when NewAtom gets called the newly created atoms will be selected and  
wouldn’t have to worry about the index thing.

Anyways, just my 2c. I wouldn’t want to do it anytime soon if we’re  
going to to try to release Avo. Needs to be linked against the stable  
version of OB.
