Radicale DecSync
Radicale DecSync is an Radicale storage plugin which adds synchronization of contacts and calendars using DecSync. This allows you to use DecSync on any CalDAV/CardDAV compatible client like Thunderbird. To start synchronizing, all you have to do is synchronize the DecSync directory (by default ~/.local/share/decsync), using for example Syncthing. It works on both Linux and Windows.
Installation
It is preferred to install the Radicale server on the same device as you will run the client on, as you can leave it remotely inaccessible in that case.
You need to install the radicale_storage_decsync package from PyPI:
pip3 install radicale_storage_decsync
Configuration
Save the following in ~/.config/radicale/config:
[storage]
type = radicale_storage_decsync
filesystem_folder = ~/.var/lib/radicale/collections
decsync_dir = ~/.local/share/decsync
You may want to adjust the filesystem_folder or decsync_dir. The filesystem_folder denotes the directory in which Radicale stores its files, its location is not very important. The decsync_dir denotes the DecSync directory, i.e. the directory you need to synchronize with other devices.
Then, to launch the Radicale server, execute
python3 -m radicale --config "~/.config/radicale/config"
When the server is launched, you can configure it at localhost:5232. By default, any username and password is accepted, which should be fine as long as you do not make the server remotely accessible. For more configuration options, see the Radicale's documentation page.
Documentation on configurating clients can be found on Radicale's clients page.
Furthermore, Radicale is not started automatically after a reboot. You need to start it manually, or set up autostart based on your OS.
