# librespot
*librespot* is an open source client library for Spotify. It enables
applications to use Spotify's service, without using the official but
closed-source libspotify. Additionally, it will provide extra features
which are not available in the official library.
Note: librespot only works with Spotify Premium.

# Unmaintained
Unfortunately I am unable to maintain librespot anymore. It should still work,
but issues and Pull requests will be ignored. Feel free to fork it and continue
development there. If a fork gains traction I will happily point to it from the
README.
# THIS FORK
As the origin is no longer maintained I wanted to have a place for a version of librespot with other peoples forks and features merged.
# THANKS
I've done noting more than make this pretty so big thanks to:
[plietar](https://github.com/plietar/) for making the thing in the first place.
[kingosticks](https://github.com/kingosticks/) For the Suffling and Repeat.
[ipha](https://github.com/ipha/) For the start stop audio sink.
## Building
Rust 1.17.0 or later is required to build librespot.
@ -46,9 +52,27 @@ Once you've built *librespot*, run it using :
target/release/librespot --username USERNAME --cache CACHEDIR --name DEVICENAME [--initial-volume 20]

## Discovery mode
*librespot* can be run in discovery mode, in which case no password is required at startup.
For that, simply omit the `--username` argument.

| Type | Short | Long | Description | Hint |
|----------|-------|---------------------|-------------------------------------------------|-------------|
| Option | c | cache | Path to a directory where files will be cached. | CACHE |
| Flag | | disable-audio-cache | Disable caching of the audio data. | |
| Required | n | name | Device name | NAME |
| Option | | device-type | Displayed device type | DEVICE_TYPE |
| Option | b | bitrate | Bitrate (96, 160 or 320). Defaults to 160 | BITRATE |
| Option | | onstart | Run PROGRAM when playback is about to begin. | |
| Option | | onstop | Run PROGRAM when playback has ended. | PROGRAM |
| Flag | v | verbose | Enable verbose output | PROGRAM |
| Option | u | username | Username to sign in with | USERNAME |
| Option | p | password | Password | PASSWORD |
| Flag | | disable-discovery | Disable discovery mode | |
| Option | | backend | Audio backend to use. Use '?' to list options | BACKEND |
| Option | | device | Audio device to use. Use '?' to list options | DEVICE |
| Option | | mixer | Mixer to use | MIXER |
