Another feature please?

JDriver · 06-26-2013, 01:54 PM

I've been using CC on my Nexus 7 ever since it was first released, and it is just the dogs do-dahs. I have searched for this feature but have been unable to find it, so here is my, admittedly clumsy, description of it.

One feature which I believe it should have is some way of marking a book 'read'. I have custom columns on Calibre which have the status of read, to read or don't bother. If I could somehow provide that information on CC and it would then uipdate the calibre record it would save making notes on scraps of paper.

Just a thought.

This is something we would like to do, but unfortunately it isn't straightforward. The first problem is that calibre's device subsystem is not permitted to write information into the database. I can get around that, but I need to be absolutely certain that whatever I do can't corrupt the database. The second problem is "synchronization": how to handle simultaneous changes to the field on the device and in calibre. How does one detect it? Which change wins?

I have had some discussion with Kovid about how I could do this in a way that is general enough to be acceptable yet has behavior that is predictable. I haven't gotten there yet.

Bottom line: we will get there eventually, but I wouldn't hold my breath.
