# 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.
**I will be very busy with other stuff until July, and won't be able to
dedicate much time to librespot. Please keep using it and open issues,
but it's likely I won't be able to answer them until then. Non-trivial
pull requests will probably not be reviewed either.**
## Building
Rust 1.15.0 or later is required to build librespot.
It also requires a C, with portaudio.
On debian / ubuntu, the following command will install these dependencies :
```shell
sudo apt-get install build-essential portaudio19-dev
```
On Fedora systems, the following command will install these dependencies :
```shell
sudo dnf install portaudio-devel make gcc
```
On OS X, using homebrew :
```shell
brew install portaudio
```
Once you've cloned this repository you can build *librespot* using `cargo`.
```shell
cargo build --release
```
## Usage
A sample program implementing a headless Spotify Connect receiver is provided.
Once you've built *librespot*, run it using :
```shell
target/release/librespot --username USERNAME --cache CACHEDIR --name DEVICENAME
```
## 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.
## Audio Backends
*librespot* supports various audio backends. Multiple backends can be enabled at compile time by enabling the
corresponding cargo feature. By default, only PortAudio is enabled.
A specific backend can selected at runtime using the `--backend` switch.
```shell
cargo build --features portaudio-backend
target/release/librespot [...] --backend portaudio
```
The following backends are currently available :
- ALSA
- PortAudio
- PulseAudio
## Cross-compiling
A cross compilation environment is provided as a docker image.
Build the image from the root of the project with the following command :
```
$ docker build -t librespot-cross -f contrib/Dockerfile .
```
The resulting image can be used to build librespot for linux x86_64, armhf and armel.
The compiled binaries will be located in /tmp/librespot-build
```
docker run -v /tmp/librespot-build:/build librespot-cross
```
If only one architecture is desired, cargo can be invoked directly with the appropriate options :
```shell
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --no-default-features --features alsa-backend
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabihf --no-default-features --features alsa-backend
docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target arm-unknown-linux-gnueabi --no-default-features --features alsa-backend
```
Don't forget to set the `with-tremor` feature flag if your target device does not have floating-point capabilities.
## Development
When developing *librespot*, it is preferable to use Rust nightly, and build it using the following :
```shell
cargo build --no-default-features --features "nightly portaudio-backend"
```
This produces better compilation error messages than with the default configuration.
## Disclaimer
Using this code to connect to Spotify's API is probably forbidden by them.
Use at your own risk.
