Debugging custom plugins

GRiker · 04-08-2011, 12:51 PM

In the user manual section on developing and debugging custom plugins, it says that you can rebuild your plugin while calibre is running, then execute the updated plugin code without relaunching calibre.

After making changes to my code and saving them as described in the manual, I'm not seeing the effects of the changed code. I've inspected the plugin zip file in the calibre config directory and confirmed that the changes were in fact written to the zip file.

Is there some other action I need to take to cause calibre to reload the updated plugin? It would save a lot of development time to be able to use this feature.

EDIT: I'm using the demo code supplied by Kovid, and changing some items in the main.py module, in the DemoDialog.__init__() method.

You have to restart calibre for the changes to show up.

The exception I found to this was for the metadata download plugins. For those I found it is possible to edit the code, then re-add the plugin using Preferences->Plugins while keeping the same Calibre instance open and it does use the new plugin code.
