Doesn't appear to work with calibre 5

[PiperKev]

I just updated my calibre installation to version 5.0.1, and the OPDS Client entry on the main toolbar disappeared. I attempted to reinstall, but it doesn't show as an available action to install on the toolbar.

Indeed!

The button is gone from my toolbar too, so this is something I will need to look into.

Thanks!

Could it be a Python issue? Calibre 5.0 uses Python 3 now. I reverted back to 4.23, which uses Python 2, and the OPDS Client button came back.

Looks like you're right: https://calibre-ebook.com/new-in/fourteen

I will need to move the plugin to python 3.

I wonder how to do that...? It's been a while since I last had to do any work on this plugin...:-)

[steinarb]

I couldn't find anything python 3 specific in the plugin.

I looked at the documentation for plugins with UI and compared with the source code. As far as I can tell the plugins follows the structure.

I've started calibre with "calibre-debug -g" and as far as I can tell calibre picks up the plugin:

The plugin also shows up in the plugins section of the Preferences dialog. But it does not show up in "Toolbars & menus" where the opds-reader toolbutton is added to the top menu bar.

I have asked a question on the calibre forums.

Still not fixed. I get errors when clicking on the button:

I have successfully read the OPDS feed of a different calibre instance, downloaded a book, and set the purchase date on that book.

So now the plugin works for me on calibre 5.01.

[PiperKev]

It works on the most recent calibre update, 5.1, as well! Thanks so much for the quick turnaround on this!

[steinarb]

You're welcome! :-)

It helped on the motivation, that I needed this for myself. :-)
