Spotify CLI

This CLI can be used to control your Spotify account. It is meant as an example project to show how to build a command line interface in a language that runs on the JVM.

Watch the talk on YouTube to learn more about this CLI!

Installation

Download a binary from the releases page, and put the binary in your $PATH.

Autocomplete

This CLI supports autocomplete for various shells (bash, zsh, fish). To enable autocomplete, source the completion script upon starting a shell (through your profile, or rc file):

source <(spot --generate-completion bash)

Replace bash with the shell of your choice.

Compiling

In order to compile the source to a valid binary (that can be run standalone), make sure that you have the following installed:

• GraalVM 20.3.0.r11 (or greater; should also work)
• Native Image GraalVM component (gu install native-image)

Make sure when running maven, you've set GraalVM as the JDK to use in that shell (hence, JAVA_HOME is set to GraalVM). Tip: use direnv, and create an .envrc file in the root of this repository, with the following contents:

export JAVA_HOME=path/to/graalvm/java_home
export PATH=$JAVA_HOME/bin:$PATH

This automatically activates and sets GraalVM as the active JDK.

Client credentials

To successfully use the CLI, make sure to create application.conf in src/main/resources, with the following contents:

cli {
  clientId = "<the client id for your Spotify app>"
  clientSecret = "<the client secret for your Spotify app>"
}

To create a clientId and clientSecret, go to the Spotify Developer dashboard.
