Lost some plugins

DavidJC · 05-03-2013, 06:04 AM

After the latest update I've lost the generate cover and Epub split pugins.

I've looked in Preferences>Toolbar they are not there. tried calibre restart, system restart, uninstall/install plugins no luck.

There was some internal refactoring in calibre, to improve startup time for the worker processes, that might have caused those plugins to need updating. They will need to change

from calibre.ebooks.metadata.book.base import SafeFormat
to
from calibre.ebooks.metadata.book.formatter import SafeFormat

Just post in the forum thread for the plugins, and their authors will hopefully be able to make the change quickly.

Thanks Kovid.

Kovid, I didn't check the revision logs - is it the case that this is backwards compatible or should the plugins be marked as needing 0.9.29 onwards?

It is backward compatible if you do this:

Code:

try:
    from calibre.ebooks.metadata.book.formatter import SafeFormat
except ImportError:
    from calibre.ebooks.metadata.book.base import SafeFormat

This will work on all versions of calibre. Otherwise you have to mark it as requiring 0.9.29
