Show supported features in --version

[redfast00]

Currently, spotifyd --version only shows:

spotifyd 0.3.5

it would be nice if it also listed if this is an official release, and which options it was (and wasn't compiled with), so for example

spotifyd 0.3.5
slim
NO mpris support
...

Sounds like a good idea. Would you be happy with something like:

spotifyd 0.3.5
features: MPRIS, keyring
audio backends: alsa, pulseaudio, rodio

That should be quite easy to implement. I'm not sure about the official release part. Is there a specific reason, you would like to see it in there?

[redfast00]

Sounds good! Is it possible to also list the features it was not compiled with maybe? If not, no worries.

As for the official release part: does not really matter to me but seemed useful, although I can't remember the usecase anymore now.

Is this issue still open? If yes, how can I start on it?

Thank you for your interest! Sure, any help is greatly appreciated. Currently, all CLI config parsing is done by structopt, see the following lines for the big config struct:

spotifyd/src/config.rs

Lines 335 to 361 in b25538f

	#[derive(Debug, Default, StructOpt)]
	#[structopt(
	about = "A Spotify daemon",
	author,
	name = "spotifyd",
	setting(AppSettings::ColoredHelp)
	)]
	pub struct CliConfig {
	/// The path to the config file to use
	#[structopt(long, value_name = "string")]
	pub config_path: Option<PathBuf>,
	/// If set, starts spotifyd without detaching
	#[structopt(long)]
	pub no_daemon: bool,
	/// Prints more verbose output
	#[structopt(long)]
	pub verbose: bool,
	/// Path to PID file.
	#[structopt(long)]
	pub pid: Option<PathBuf>,
	#[structopt(flatten)]
	pub shared_config: SharedConfigValues,
	}

So the --version is auto-generated and can maybe be changed with some options in the #[structopt(...)] block above.

If you need some further hints, where to look, feel free to join the matrix. I try to be somewhat responsive there and help where I can.
