MumbleDJ
========
A Mumble bot that plays music fetched from YouTube videos.

**IMPORTANT NOTE:** If you were using the Lua version of MumbleDJ previously, you will need to follow the installation guide once more to install new dependencies.

## USAGE
`$ mumbledj -server=localhost -port=64738 -username=MumbleDJ -password="" -channel=root`  
All parameters are optional, the example above shows the default values for each field.

## COMMANDS
These are all of the chat commands currently supported by MumbleDJ. All command names and command prefixes may be changed in `mumbledj.gcfg`. All fields surrounded by `<>` indicate fields that *must* be supplied to the bot for the command to execute. All fields surrounded by `<>?` are optional fields.

####`!add <youtube_url>`
Adds a YouTube video's audio to the song queue. If no songs are currently in the queue, the audio will begin playing immediately.

####`!skip`
Submits a vote to skip the current song. Once the skip ratio target (specified in `mumbledj.gcfg`) is met, the song will be skipped and the next will start playing. Each user may only submit one skip per song.

####`!forceskip`
An admin command that forces a song skip.

####`!volume <desired_volume>?`
Either outputs the current volume or changes the current volume. If `desired_volume` is not provided, the current volume will be displayed in chat. Otherwise, the volume for the bot will be changed to `desired_volume` if it is within the allowed volume range.

####`!move <channel>`
Moves MumbleDJ into `channel` if it exists.

####`!reload`
Reloads `mumbledj.gcfg` to retrieve updated configuration settings.

####`!kill`
Safely cleans the bot environment and disconnects from the server. Please use this command to stop the bot instead of force closing, as the kill command deletes any remaining songs in the `~/.mumbledj/songs` directory.

## INSTALLATION
Installation for v2 of MumbleDJ is much easier than it was before, due to the reduced dependency list and a `Makefile` which automates some of the process.  

**NOTE:** This bot was designed for use on Linux machines. If you wish to run the bot on another OS, it will require tweaking and is not something I will be able to help with.

**SETUP GUIDE**  
**1)** Install and correctly configure [`Go`](https://golang.org/). Specifically, make sure to follow [this guide](https://golang.org/doc/code.html) and set the `GOPATH` environment variable properly.

**2)** Install [`ffmpeg`](https://www.ffmpeg.org/) if it is not already installed on your system.

**3)** Install [`youtube-dl`](https://github.com/rg3/youtube-dl#installation).

**4)** Clone the `MumbleDJ` repository or [download the latest release](https://github.com/matthieugrieger/mumbledj/releases).

**5)** `cd` into the `MumbleDJ` repository directory and execute the following commands: 
```
$ make install_deps
$ make
$ make install
```

**5)** Edit `~/.mumbledj/config/mumbledj.gcfg` to your liking. This file will be overwritten if the config file structure is changed in a commit, but a backup is always stored at `~/.mumbledj/config/mumbledj_backup.gcfg`.

**6)** Execute the command shown at the top of this `README` document with your credentials, and the bot should be up and running!
