[GUI Plugin] Marvin XD

[AndrewG]

I have updated the iOS reader applications and Marvin XD plugins and all works well with Calibre 1.48. When I try to upgrade to Calibre 2.1 I get a connection error message and Marvin does not work correctly.

I am using Mac OSX 10.9.4 and an iPad2.

Here is the error log. I hope that this is helpful.

Hopefully, but I'm beginning to think there is something else going on.

AndrewG: Do the delete suggested and tell us if that helps.

[AndrewG]

I did the delete (booklist.db) and tried Calibre 2.1 again.

I get a very similar error message (appended).

By the way my ipad is running iOS 7.1.2

I also tried uninstalling iOS reader applications and marvin plugins, deleting all references to the calibre configuration directory, shutting down calibre, starting calibre 2.1 and reinstalling the plugins, but still got the same error condition.

I'm investigating this issue. I'm fairly sure the source of the problem is identical to the iOSRA one so you might want to watch that thread, too.

Preliminary findings are here:

Thank you Philantrop. I will follow developments on the IOSRA forum with interest.

Hi --
Thanks for the new release! It is working 95% here. The one problem is that when I choose to explore Marvin library it does show the colored fields for the metadata choices. But let's say I double click on a title with a yellow background. That should show me the metadata in both Calibre and in Marvin. However, it gives a dialog box x with the error:

ImportError:No module named PyQt4

If I ask for details here is what it dumps:

What can I do? Thanks,

Neil: Open the calibre preferences directory and go into the plugins directory. Delete everything the "Marvin_XD_resources/dialogs" directory. These should be rebuilt correctly the next time you start calibre.

[Neil]

That did it! Thanks very much!!

Hi,
Can you tell me where/how to find the "calibre preferences directory"? I am using Calibre 2.2 64bit on Windows 7. I have a "Calibre2" folder, but nothing within it called Preferences.

Thanks!


P.S. Post Calibre 2, I used the Calibre Preferences/Plugins dialogue and "Remove Plugin" to remove both iOS reader Applications and Marvin XD. I restarted Calibre and upgraded from 2.1 to 2.2. I then installed (apparently successfully) iOS Reader Applications 1.4.3. and re-started Calibre. Attempting to now "Customize the Plugin" gets me the error:

"ImportError: cannot import name ConfigWidget"

- Open Calibre
- Go to Preferences | Advanced | Miscellaneous, click Open calibre configuration directory.
- Open the plugins folder.

You'll find the directory davidfor mentioned there.

Thanks Philantrop & davidfor et al.!. Success!

What I did: I again uninstalled iOS Reader plugin (Marvin XD was already uninstalled). Re-started Calibre, and went to the directory as described above. There I found two folders/directories, one for iOS Reader and one for Marvin. For good or bad, I just went ahead and deleted both folders and contents. There were also a few files in the main directory that also referenced iOS reader and Marvin, and for good or bad, decided to delete those as well.

I then re-started Calibre and then re-installed iOS Reader plugin, and re-started Calibre. And success! Can now access that plugin's configuration. Then proceeded to install Marvin again. Then back to the iOS reader to configure it for Marvin, as one would normally do.

All working now. Thanks again!

[Philantrop]

k9reeder, glad to hear it worked. From the next version on, I'm going to avoid such issues entirely even though they should only occur once such a major change in Calibre is implemented as has been the case for 2.0.

@Philantop, I suggest you read the thread on the Derive Genres plugin starting with post #6. It may have something to do with Marvin XD that you'll want to read.
