[Library Closed Plugin] Save Virtual Libraries To Column

chaley · 04-01-2016, 06:06 AM

When a library is closed (calibre exit or change library) this plugin examines every book in the library to determine which virtual libraries contain the book. The virtual library names for the book are written to a selected custom column, which must be of type "comma-separated text, behaves like tags".

Note: this plugin also exists as a "GUI Plugin". The two plugins share configuration information (the custom column to modify).

Special Notes:

Requires Calibre 2.54 or later

Configuration:

To choose which custom column for the library names, go to calibre's Preferences / Plugins / Library Closed plugins. Select this plugin, press the "Customize plugin" button, and fill in the box appropriately. Note that this plugin and is GUI sibling share the same configuration. Setting it in one plugin will also set it in the other.

Installation Notes:

Download the attached zip file and install the plugin/restart Calibre as described in the Introduction to plugins thread.
Note that this is not a GUI plugin so it is cannot be added to context menus/toolbars etc.

Version History:

Version 2: change to update the column for a book only if the contents have changed. This avoids setting the last_modified date when nothing is different.

I am using both plugins and they work nearly like i want it: Update when calibre quits or on change of library, or with the gui-plugin when a device disconnects.
So it would be extremely great if it would update the VL-column when a certain row changes (in my case tags)
So i use the gui-plugin by hand. By the way, it only updates the VL-column, when i close the gui-plugin manually... Is that behaviour "normal"
Thank you for your help!
PS: Which contents have to change to update the VL-column?
