If you include a config.json file with a JSON dictionary in it, Anki will allow users to edit it from the add-on manager.
A simple example: in config.json:
This is documentation for this add-on's configuration, in *markdown* format.
In your add-on’s code:
from aqt import mw config = mw.addonManager.getConfig(__name__) print("var is", config['myvar'])
When updating your add-on, you can make changes to config.json. Any newly added keys will be merged with the existing configuration.
If you change the value of existing keys in config.json, users who have customized their configuration will continue to see the old values unless they use the "restore defaults" button.
If you need to programmatically modify the config, you can save your changes with:
If no config.json file exists, getConfig() will return None - even if you have called writeConfig().
Add-ons that manage options in their own GUI can have that GUI displayed when the config button is clicked:
Avoid key names starting with an underscore - they are reserved for future use by Anki.
When your add-on needs configuration data other than simple keys and values, it can use a special folder called user_files in the root of your add-on’s folder. Any files placed in this folder will be preserved when the add-on is upgraded. All other files in the add-on folder are removed on upgrade.
To ensure the user_files folder is created for the user, you can put a README.txt or similar file inside it before zipping up your add-on.
When Anki upgrades an add-on, it will ignore any files in the .zip that already exist in the user_files folder.
