Implement login dialog

[hrkfdn]

Requiring new users to create a configuration themselves is not user-friendly.

Create a dialog asking for Spotify credentials on startup/when login credentials are missing.

Does this way of doing it even work with accounts created through Facebook?

There is a workaround for facebook auth: Go to your Spotify account settings and go to something like "Set Device Password"

The password entered there can be put into ncspot's config file.

I've also been working on getting the third party auth flow to work with Facebook in medwards/ncspot/master, but I'm not sure how to debug my crash. ncurses seems to take over, flash something to the terminal, then wipe it before exiting with code 101. My guess is there is some auth related unwrap in some thread and it brings the entire thing down, but I'm not sure how to debug this. Will gdb or cgdb play nicely with ncspot?

You can reproduce by creating a .config/ncspot file with no password and an empty or junk auth field.

You can log the backtrace to a file like so: RUST_BACKTRACE=full cargo run 2> stderr.log

Thanks, that was helpful. I assumed ncurses would somehow capture stderr.

I got my hacky approach to work: medwards/ncspot@f9af3bb

My ideal final version has librespot updating to serde 1.0 and then .config/ncspot is expected to be a toml serialized librespot Credentials struct

I may be in the minority, but I preferred username/password in config (multiple terminals. Easier to copy) I noticed an auth type parameter in the .toml but can't find documentation. Is this doable?
