Hi,
I'm looking for someone who wants to help me maintain this plugin, because I don't use it all that much anymore. Please contact me if you're up for this.
Harm
A calibre plugin to synchronize metadata from KOReader to calibre.
KOReader creates sidecar files that hold read progress and annotations. This plugin reads the data from those sidecar files and updates calibre's metadata based on them. It is inspired by the Kobo Utilities plugin, that synchronizes reading progress between the original Kobo firmware ("Nickel") and custom columns in calibre.
Note that at the moment the sync is primarily one-way—from the KOReader device to calibre, and only works for USB and wireless devices. For the latter, you'll need KOReader 2021.04 or newer.
Pushing metadata from calibre to KOReader currently works only for books which do not have KOReader sidecar files, and of course requires the raw metadata column to be mapped. The use-case is for setting up a new device, or if a book was removed from your device and you've now added it back. This has been tested for calibre's Connect to Folder and Custom USB Device modes. It does not seem to work for the Kobo Touch device driver nor with wireless connections, but I (@charlesangus) find those don't communicate perfectly with Calibre/KOReader in any case... I haven't disabled it for other devices - it may be a quirk in my setup which is causing it to fail, and it may work fine for you.
Releases will also be uploaded to this plugin thread on the MobileRead Forums. If you are on there as well, please let me know what you think of the plugin in that thread.
- Go to your calibre's Preferences > Plugins > Get new plugins and search for KOReader Sync
- Click Install
- Restart calibre
- Download the latest release from here.
- Go to your calibre's Preferences > Plugins > Load plugin from file and point it to the downloaded ZIP file
- Restart calibre
- Pick and choose the metadata you would like to sync and create the appropriate columns in calibre. These are your options:
- A Floating point numbers column to store the current percent read, with Format for numbers set to
{:.0%}
. - An Integers column to store the current percent read.
- A regular Text column to store the location you last stopped reading at.
- A Rating column to store your rating of the book, as entered on the book's status page.
- A Long text column to store your review of the book, as entered on the book's status page.
- A regular Text column to store the reading status of the book, as entered on the book status page (Finished, Reading, On hold).
- A Yes/No column to store the reading status of the book, as a boolean (Yes = Finished, No = everything else).
- A Date column to store the date on which the first highlight or bookmark was made. (This is probably around the time you started reading.)
- A Date column to store the date on which the last highlight or bookmark was made. (This is probably around the time you finished reading.)
- A Long text column to store your bookmarks and highlights of the book, with Interpret this column as set to Plain text formatted using markdown. (Highlights are an unordered list with their metadata in an HTML comment.)
- A regular Text column to store the MD5 hash KOReader uses to sync progress to a KOReader Sync Server. (Progress sync in the KOReader app.) This might allow for syncing progress to calibre without having to connect your KOReader device, in the future.
- A Date column to store when the last sync was performed.
- A Date column to store when the sidecar file was last modified.',
- A Long text column to store the contents of the metadata sidecar as JSON, with Interpret this column as set to Plain text. This is required to sync metadata back to KOReader sidecars.
- A Floating point numbers column to store the current percent read, with Format for numbers set to
- Add KOReader Sync to main toolbar when a device is connected, if it isn't there already.
- Right-click the KOReader Sync icon and Configure.
- Map the metadata you want to sync to the newly created calibre columns.
- Click OK to save your mapping.
- From now on just click the KOReader Sync icon to sync all mapped metadata for all books on the connected device to calibre.
- The plugin overwrites existing metadata in Calibre without asking. That usually isn’t a problem, because you will probably only add to KOReader’s metadata. But be aware that you might lose data in calibre if you’re not careful.
- Pushing sidecars back to KOReader currently only happens for sidecars which are missing. For now, manually delete the
<bookname>.sdr
folder from the device before attempting to push the sidecars back to KOReader for any books you would like to overwrite the current metadata with Calibre's metadata. - When pushing missing sidecars to the device, no attempt is made to convert Calibre's metadata to account for changes in KOReader's sidecar format. Old metadata may work unpredictably if it's from a different version of KOReader.
This plugin has been tested successfully with:
- Kobo Aura connected over USB, which means it will probably work for all comparable Kobo devices (
KOBO
andKOBOTOUCH
) - Kobo Aura H2O over USB (
KOBOTOUCHEXTENDED
, see #6 for details) - Kobo Aura connected wirelessly, which means it will probably work for all calibre connect devices (
SMART_DEVICE_APP
) - A connected folder (
FOLDER_DEVICE
) - Kindle Keyboard (
KINDLE2
, see #1 for details) - Tolino Vision 4 HD (
TOLINO
, see this comment for details) - PocketBook Touch Lux 5 (which uses the
POCKETBOOK626
driver, so it will probably work for all comparable PocketBook devices, see #8 for details) - PocketBooks that use the
POCKETBOOK622
driver
This plugin is not compatible with:
MTP_DEVICE
(see #2 for details)
If you encounter any issues with the plugin, please submit them here.
- Multiple tweaks and bug fixes by Glen Sawyer
- Additional functionality by Charles Taylor
- Contains SirAnthony's SLPP to parse Lua in Python.
- Some code borrowed from--and heavily inspired by--the great Kobo Utilities calibre plugin.
- My first attempt was actually to sync calibre with KOReader's read progress through the progress sync plugin and a sync server. Read here why that did not work. This plugin might actually make that possible now by allowing you to store KOReader's MD5 hash in calibre...
- calibre allows you to auto-connect to a folder device on boot, which greatly speeds up your workflow when testing. You can find this under "Preferences" > "Tweaks", search for
auto_connect_to_folder
. Point that to thedummy_device
folder in this repository. (I have included royalty free EPUBs for your and my convenience.) - If you're testing and don't actually want to update any metadata, set
DRY_RUN
toTrue
in__init__.py
. - I work in PyCharm, which offers a remote debugging server. To enable that in this plugin, set
PYDEVD
toTrue
in__init__.py
.You might need to changesys.path.append
inaction.py
. - The supported device drivers can be found in the
SUPPORTED_DEVICES
list inconfig.py
. Adding a new type here is the first step to adding support, but make sure all features are tested thoroughly before releasing a version with an added device
Use make to load the plugin into calibre and launch it:
make dev
Alternatively, build a release and load that:
make zip load
Make sure you have the dependencies and have set the correct version number in __init__.py
, pluginIndexKOReaderSync.txt
and Makefile
. Also update Changelog. Then:
make zip
- Download the required release from here
- Add it to calibre by running this in your terminal:
calibre-customize -a "KOReader Sync vX.X.X-alpha.zip"
, whereX.X.X
refers to the version you downloaded - Start calibre in debug mode with
calibre-debug -g
- Configure the KOReader plugin as described here
- Connect your device
- Run the sync by clicking the KOReader icon in your toolbar
- Check the details of the message when it's done if any/all books have been synced correctly
- Check your (custom) columns for one of those books to see if their contents are what they should be
- Check the output in your terminal for lines containing
koreader
to see what it did
All notable changes to this project will be documented here.
The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.
