## Features
* Plays audio from many media websites, including YouTube, SoundCloud, and Mixcloud.
* Supports playlists and individual videos/tracks.
* Displays metadata in the text chat whenever a new track starts playing.
* Incredibly customizable. Nearly everything is able to be tweaked via configuration files (by default located at `$HOME/.config/mumbledj/config.yaml`).
* A large array of [commands](#commands) that perform a wide variety of functions.
* Built-in vote-skipping.
* Built-in caching system (disabled by default).
* Built-in play/pause/volume control.
## Installation
**IMPORTANT NOTE:** MumbleDJ is only tested and developed for Linux systems. Support will not be given for non-Linux systems if problems are encountered.
### Requirements
**All MumbleDJ installations must also have the following installed:**
* [`youtube-dl`](https://rg3.github.io/youtube-dl/download.html)
* [`ffmpeg`](https://ffmpeg.org) OR [`avconv`](https://libav.org)
* [`aria2`](https://aria2.github.io/) if you plan on using services that throttle download speeds (like Mixcloud)
**If installing via `go install` or from source, the following must be installed:**
* [Go 1.5+](https://golang.org)
* __NOTE__: Extra installation steps are required for a working Go installation. Once Go is installed, type `go help gopath` for more information.
* If the repositories for your distro contain a version of Go older than 1.5, try using [`gvm`](https://github.com/moovweb/gvm) to install Go 1.5 or newer.
#### YouTube API Key
A YouTube API key must be present in your configuration file in order to use the YouTube service within the bot. Below is a guide for retrieving an API key:
**1)** Navigate to the [Google Developers Console](https://console.developers.google.com) and sign in with your Google account, or create one if you haven't already.
**2)** Click the "Create Project" button and give your project a name. It doesn't matter what you set your project name to. Once you have a name click the "Create" button. You should be redirected to your new project once it's ready.
**3)** Click on "APIs & auth" on the sidebar, and then click APIs. Under the "YouTube APIs" header, click "YouTube Data API". Click on the "Enable API" button.
**4)** Click on the "Credentials" option underneath "APIs & auth" on the sidebar. Underneath "Public API access" click on "Create New Key". Choose the "Server key" option.
**5)** Add the IP address of the machine MumbleDJ will run on in the box that appears (this is optional, but improves security). Click "Create".
**6)** You should now see that an API key has been generated. Copy/paste this API key into the configuration file located at `$HOME/.config/mumbledj/mumbledj.yaml`.
#### SoundCloud API Key
A SoundCloud client ID must be present in your configuration file in order to use the SoundCloud service within the bot. Below is a guide for retrieving a client ID:
**1)** Login/sign up for a SoundCloud account on https://soundcloud.com.
**2)** Create a new app: https://soundcloud.com/you/apps/new.
**3)** You should now see that a client ID has been generated. Copy/paste this ID (NOT the client secret) into the configuration file located at `$HOME/.config/mumbledj/mumbledj.yaml`.
### Via `go get` (recommended)
After verifying that the [requirements](#requirements) are installed, simply issue the following command:
```
go get -u github.com/matthieugrieger/mumbledj
```
This should place a binary in `$GOPATH/bin` that can be used to start the bot.
**NOTE:** If using Go 1.5, you MUST execute the following for `go get` to work:
```
export GO15VENDOREXPERIMENT=1
```
### Pre-compiled Binaries (easiest)
Pre-compiled binaries are provided for convenience. Overall, I do not recommend using these unless you cannot get `go install` to work properly. Binaries compiled on your own machine are likely more efficient as these binaries are cross-compiled from a 64-bit Linux system.
After verifying that the [requirements](#requirements) are installed, simply visit the [releases page](https://github.com/matthieugrieger/mumbledj/releases) and download the appropriate binary for your platform.
### From Source
First, clone the MumbleDJ repository to your machine:
```
git clone https://github.com/matthieugrieger/mumbledj.git
```
Install the required software as described in the [requirements section](#requirements), and execute the following:
```
make
```
This will place a compiled `mumbledj` binary in the cloned directory if successful. If you would like to make the binary more accessible by adding it to `/usr/local/bin`, simply execute the following:
```
sudo make install
```
### Docker
You can also use [Docker](https://www.docker.com) to run MumbleDJ.
First you need to clone the MumbleDJ repository to your machine:
```
git clone https://github.com/matthieugrieger/mumbledj.git
```
Assuming you have [Docker installed](https://www.docker.com/products/docker), you will have to build the image:
```
docker build -t mumbledj .
```
And then you can run it, passing the configuration through the command line:
```
docker run --rm --name=mumbledj mumbledj --server=SERVER --api_keys.youtube=YOUR_YOUTUBE_API_KEY --api_keys.soundcloud=YOUR_SOUNDCLOUD_API_KEY
```
In order to run the process as a daemon and restart it automatically on reboot you can use:
```
docker run -d --restart=unless-stopped --name=mumbledj mumbledj --server=SERVER --api_keys.youtube=YOUR_YOUTUBE_API_KEY --api_keys.soundcloud=YOUR_SOUNDCLOUD_API_KEY
```
You can also install Docker on a [Raspberry Pi](https://www.raspberrypi.org/) for instance with [hypriot](http://blog.hypriot.com/getting-started-with-docker-on-your-arm-device/) or with [archlinux](https://archlinuxarm.org/packages/arm/docker). You just need to build the ARM image:
```
docker build -f raspberry.Dockerfile -t mumbledj .
```
## Usage
MumbleDJ is a compiled program that is executed via a terminal.
Here is an example helptext that gives you a feel for the various commandline arguments you can give MumbleDJ:
```
NAME:
MumbleDJ - A Mumble bot that plays audio from various media sites.
USAGE:
mumbledj [global options] command [command options] [arguments...]
VERSION:
v3.1.0
COMMANDS:
GLOBAL OPTIONS:
--config value, -c value location of MumbleDJ configuration file (default: "/home/matthieu/.config/mumbledj/config.yaml")
--server value, -s value address of Mumble server to connect to (default: "127.0.0.1")
--port value, -o value port of Mumble server to connect to (default: "64738")
--username value, -u value username for the bot (default: "MumbleDJ")
--password value, -p value password for the Mumble server
--channel value, -n value channel the bot enters after connecting to the Mumble server
--p12 value path to user p12 file for authenticating as a registered user
--cert value, -e value path to PEM certificate
--key value, -k value path to PEM key
--accesstokens value, -a value list of access tokens separated by spaces
--insecure, -i if present, the bot will not check Mumble certs for consistency
--debug, -d if present, all debug messages will be shown
--help, -h show help
--version, -v print the version
```
__NOTE__: You can also override all settings found within `config.yaml` directly from the commandline. Here's an example:
```
mumbledj --admins.names="SuperUser,Matt" --volume.default="0.5" --volume.lowest="0.2" --queue.automatic_shuffle_on="true"
```
Keep in mind that values that contain commas (such as `"SuperUser,Matt"`) will be interpreted as string slices, or arrays if you are not familiar with Go. If you want your value to be interpreted as a normal string, it is best to avoid commas for now.
