Calibre OPDS client

What’s this?

This is a calibre plugin that is an OPDS client intended to read the contents of another calibre installation, find the differences to the current calibre and offer to copy books from the other calibre into the current calibre

How do I install it?

Requires git and calibre installed (minimum calibre version: 6 (because the plugin now uses PyQt6)):

Clone the repository:

git clone https://github.com/steinarb/opds-reader.git

Install the plugin in calibre

cd opds-reader/calibre_plugin/
calibre-customize -b .

Start calibre (if calibre was already running, stop calibre and start it again)
Click the button “Preferences”
In the dialog “calibre - Preferences”:
- Under “Interface”, click on the button “Toolbar”
- In the dialog “calibre - Preferences - Toolbar”:
  - In the dropdown, select “The main toolbar”
  - In “Available actions” scroll down to find “OPDS Client” and select it
  - Click the top arrow button (arrow pointing right)
  - Click the “Apply” button
- Click the “Close” button

How do I use it?

I made this tool to backup my book collection between two PCs in my home LAN, and that is the procedure I will document here:

In the calibre you wish to copy from (in this example called calibre1.home.lan):
1. Click Preferences
2. In the “calibre - Preferences” dialog:
  1. Click “Sharing over the net”
  2. In the “calibre - Preferences - Sharing over the net” dialog:
    1. Click the “Start Server” button
    2. Select the checkbox “Run server automatically when calibre starts”
    3. Click the “Apply” button
  3. Click the “close” button
In the calibre you wish to copy to
1. Install this plugin (see the “How do I install it?” section)
2. Click the “OPDS client” button
3. In the “OPDS client” dialog
  1. Edit the “OPDS URL” value, change
```
http://localhost:8080/opds
            
```
    to
```
http://calibre1.home.lan:8080/opds
            
```
    and then press the RETURN key on the keyboard
  2. Click the “Download OPDS” button
  3. Wait until the OPDS feed has finished loading (this may take some time if there is a large number of books to load)
    - Note: if no books appear, try unchecking the “Hide books already in the library” checkbox. If that makes a lot of books appear, it means that the two calibre instances have the same books
  4. select the books you wish to copy into the current calibre and click the “Download selected books”
    - calibre will start downloading and installing the books:
      - The Jobs counter in calibre’s lower right corner, will show a decrementing number and the icon will spin
      - The book list will be updated as the books are downloaded
  5. The downloaded books will be in approximately the same order as in the original, but the time stamp will be the download time. To fix the time stamp, click on the “Fix timestamps of the selection” button
    - The updated timestamps may not show up immediatly, but they will show up after the first update of the display, and the books will be ordered according to the timestamp after stopping and starting calibre

Troubleshooting

Nothing happens when I click on “Download OPDS” and the URL I typed in isn’t preserved

Make sure you press Enter after finishing typing into the URL combo box. This will download the top OPDS catalog for the OPDS feed.

How to I debug the plugin

If the plugin doesn’t work for some reason, start calibre in debug mode and see what ends up in the console.

To start calibre in debug mode, open a command line window, and type:

calibre-debug

If necessary, add “print()” statements to the code to check that its get to the places you expect it to get and start printing out variables.

Attempting to grab from the Standard Ebooks OPDS feed

[Bug] Download OPDS->time data 'None' does not match format ...

I'm not sure which entry is problematic (Published?), but there is a parsing issue that occurs after clicking 'Download OPDS'. Some of my entries cannot have a Published date because they're ancient, such as Shakespearean texts, as an example.

Select book format to download from OPDS feed

I don't know if this is possible or not, but is there any way to select the format of the book that can be downloaded from the OPDS feed? For example, I use the OPDS client to check for revisions to ebooks from Standard Ebooks (https://standardebooks.org/opds). When I select a book to download, it automatically downloads the epub format, which I really can't use since I have a kindle (I know, I can convert with calibre, but I'd rather have it in the azw3 format that SE provides).

Hi, i get an error on calibre 3:

I think calibre changed something. Installing python module (pip install feedparser) did not help because this is related to
from calibre.web.feeds import feedparser

On the calibre website, under "What's New" there's this:

"Because calibre has now moved to Qt 6, some third party plugins will no longer work, until they are also ported to Qt 6. Fortunately, plugin developers were given over half a year to port their plugins, so most have already been ported."

Exception while downloading books

I think I saw something similar when downloading the opds itself, but I wasn't paying attention then. Download continues ok in spite of these exceptions. Maybe it happens when an entry does not have a timestamp, if that is possible?

Can't install plugin

Hi,

Can't install plugin, because:

zsh: command not found: calibre-customize

[Feature Request] Download All Button

A 'Download All' button might be nice to have (allowing for hiding any books in user library already).

Edit: A button to 'select all' might be better, it'd allow for more fine-grain control in the end.
Edit: For now, I've set the SelectionMode to QAbstractItemView::ExtendedSelection which allows cursor drag-selection.

Button missing in Calibre 5.44

Calibre 5.44.0
OS: Windows8.1
The plugin is installed normally, but there is no button.

auth not supported

I tried to load my fbreader library (https://books.fbreader.org/opds), but it needs google oauth2 (for web applications), which isn't supported.

Add an exclusion list

The exlusion list, is a list of books that should be permanently hidden from the comparison.

Plugin hanging when browsing catalog

Hello !
I just installed the plugin and I must admit it's a great tool :)
Unfortunately when browsing a catalog (http://gallica.bnf.fr/opds), I can list the different categories and download the catalogs to be displayed in the plugin windows, but then it freezes and I can't select any book to be downloaded.

How can I provide information to help debugging ?

Here is a screenshot when it's freezing : Screenshot

Cheers

Keep the line length correct during intermediate model updates

When updating the book list model after each OPDS chunk, the line heights are wrong.

The line heights are corrected after the final read but they look a bit silly during the intermediate chunks.

Add cover thumbnails to the list of books

It would look a lot better with thumbnails

Get better matching with existing books

E.g. the "Maven cookbook" was already present, but it still showed up as a new download candidate.

[Functional Request] Interface Size

On devices with smaller screens, it can be impossible to use the UI. Perhaps designing the UI to be friendly to smaller viewports such as 720p or even 480p might be nice.

maybe insufficient recursion before looking for books?

When trying to use the "Popular" OPDS from http://m.gutenberg.org/ebooks/?format=opds (used as an example that you can easily reach, my COPS installation triggers the same error) I receive an error that the author attribute cannot be found. My feeling is that the opds-reader is not recursing sufficiently deeply into the XML responses to actually find books, finding a list of categories without books may cause this error.

Perhaps use the Bonjour protocol? (is this what FBReaderJ uses?)

Hi,
I wan't use this plugin with a calibre-web generated opds.
My server is private and authentification must be use.
Does this plugin support basic authentification from calibre-web?
Thanks for your help!

Refresh the list as books are downloaded (suppress downloaded books from the list)

Doesn't this already happen?

Doesn't appear to work with calibre 5

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.
