Save database and config files to user .config folder

[NotJoeMartinez]

The script currently saves the database to the current working directory, ideally it should be some where in ~/.local/share/yt-fts/subtitles.db. I don't know the best practices for writing software that "invites itself" to a users config directories.

My general questions are:

• Do I prompt the user for a config path or just make one without asking?
• Where do I store these configs on different platforms?
• Do packages installed through pypi have the system permissions to do this on their own?
• How ispip uninstall yt-fts supposed to know where this is?

Do I prompt the user for a config path or just make one without asking?

Generally, CLI tools will either be explicit about input / output files and those will be referenced as arguments, or config will be implicitly created in the background. I think ~/.local/share/yt-fts/ is a sane choice but it would be better to allow it to be overridden:

Path(os.getenv('XDG_DATA_HOME', '~/.local/share'), 'yt-fts').expanduser()
But that path won't work for Windows. Well... I mean it will if you use pathlib and make all the parent folders but it will look weird and users won't expect it. You'll need to do some research here

Where do I store these configs on different platforms?

Do packages installed through pypi have the system permissions to do this on their own?

Yes. Other python programs will try to write to similar folders like that under the user folder.

How ispip uninstall yt-fts supposed to know where this is?

It's probably possible but I don't think pip should know. Generally programs don't delete user files or data files. If they do then people get mad
