Description shenlebantongying 2021-10-06 12:12:44 UTC 
I want to automate the reading progress over my large pile of PDFs. 

I need the ability to let my other programs know where I read the last page when close the PDF.

Okular can remember the lasted opened position (i think?), but I want to have a bird-overview of my reading progress on all my PDFs.

If I can the last page of reading from `stdout` when I exit Okular, I can automatically put that value into my databases.

What if, let's say `Okular --log nice.pdf`, then I can open okular via a script then send the value to database. Scripting a GUI application! 

I might be the only want this :/

Probably this should be made as a standalone application.

Does Okualr can be used as a KPart?

No, this shouldn't be a standalone application.

If you already have an existing solution for bibliography management, like Zotero, you don't want to duplicate the functionality.

Yes, not only the last position. Okular stores the viewport history in XML files, usually under ~/.local/share/okular/docdata/. It should be possible to parse these, although not very convenient.

No, this is one use case for D-Bus. You can try the application d-feet to look which D-Bus methods are available in Okular. For example, you can query the currentPage() method. Of course, you need to query it before Okular is closed.

> Does Okualr can be used as a KPart?

Yes, the okularpart component, which is used by the “Okular” desktop application, is actually a KPart in a shared library. It provides the same currentPage() method.

Sorry, but you're asking for something super strange, I see no reason at all why we would add such an option to Okular.
