Hi Aleksey,thank you for updating this addon,but when I opened it some errors popped up

Hi @SOREMUZ ,
Thanks for reporting

This error happens if Anki can't write "Fast Word Query" config file (_fastwqcfg.json) into the user's home directory. I guess it will be /Users/chikane/_fastwqcfg.json on your machine.
This is related to filesystem configuration of your machine. To simplify your investigation I added full path to log and to error message. E.g. 2023-11-07 00:20:20,422 Config update DEBUG Update file: /home/aleks/_fastwqcfg.json.

Try to update the add-on, find exact path to the config file and check why this file is read-only.

Logs location on your machine: /Users/chikane/Library/Application Support/Anki2/addons21/1956435337/fastwordquery-3.log

Please, let me know about the results.

I tried to add the following code to the context.py file,then the addon works fine now.

wp = mw.pm.profileFolder()
mediaPath = os.path.join(wp, "collection.media")
os.chdir(mediaPath)

Hi @SOREMUZ ,

I see in your logs that you're running Anki from the file system root (/). So, "Fast Query Word" add-on tries to write config to /_fastwqcfg.json, but this folder is read-only.

I modified add-on logic in such way that it stores config file into "user home directory" instead of "current working directory". In your case, the config file will be stored at /Users/chikane/_fastwqcfg.json, which is writable usually. Please, upgrade your Anki to the latest version.

In your code snippet, you store the config file within the collection data directory, which is not a proper place for plugin configs. Copy you config /Users/chikane/Library/Application Support/Anki2/chikane/collection.media/_fastwqcfg.json to /Users/chikane/_fastwqcfg.json to preserve your settings.
