Book matching logic?

[luca-salga]

Hi guys. What book matching logic does KoInsight implement? Some form of a hash on the book file?
If so, would it be possible to make it so users could select other matching logics, such, for example, file name?
Thanks!

Hi. KoInsight uses the hash values generated by KoReader. This is necessary to find statistics and annotations, which are handled by KoReader on the device. Since KoReader itself uses these hashes to identify books (for statistics, annotations, sync, ...), KoInsight just follows that same logic. There is no separate matching happening in KoInsight.

I don't think it would be feasible to use something else and would likely introduce mismatches with KoReader. Is there any specific usecase you have in mind?

Got it.

My use case: I sometimes review metadata of my books (epubs only) adding minor details, and then save the metadata to the file itself.

I read from two devices, and sometimes it will happen that on one device the epub of a book will be slightly different from the one on another device, due to my metadata editing.

This will in turn cause different MD5 hashes.

I've seen this before with a couple of plugins used to synchronize highlights, but managed to solve it because they give the option to use filename as opposed to MD5 hash to match the books.

And that's where my question came from!

Thanks!
