# IRC!Radio
IRC!Radio is a radio station for IRC channels. You hang around
on IRC, adding YouTube songs to the bot, listening to it with
all your friends. Great fun!
### Stack
IRC!Radio aims to be minimalistic/small using:
- Python >= 3.7
- SQLite
- LiquidSoap >= 1.4.3
- Icecast2
- Quart web framework
## Ubuntu installation
No docker. The following assumes you have a VPS somewhere with root access.
#### 1. Requirements
As `root`:
```
apt install -y liquidsoap icecast2 nginx python3-certbot-nginx python3-virtualenv libogg-dev ffmpeg sqlite3
ufw allow 80
ufw allow 443
```
When the installation asks for icecast2 configuration, skip it.
#### 2. Create system user
As `root`:
```text
adduser radio
```
#### 2. Clone this project
As `radio`:
```bash
su radio
cd ~/
git clone https://git.wownero.com/dsc/ircradio.git
cd ircradio/
virtualenv -p /usr/bin/python3 venv
source venv/bin/activate
pip install -r requirements.txt
```
#### 3. Generate some configs
```bash
cp settings.py_example settings.py
```
Look at `settings.py` and configure it to your liking:
- Change `icecast2_hostname` to your hostname, i.e: `radio.example.com`
- Change `irc_host`, `irc_port`, `irc_channels`, and `irc_admins_nicknames`
- Change the passwords under `icecast2_`
- Change the `liquidsoap_description` to whatever
When you are done, execute this command:
```bash
python run generate
```
This will write icecast2/liquidsoap/nginx configuration files into `data/`.
#### 4. Applying configuration
As `root`, copy the following files:
```bash
cp data/icecast.xml /etc/icecast2/
cp data/liquidsoap.service /etc/systemd/system/
cp data/radio_nginx.conf /etc/nginx/sites-enabled/
```
#### 5. Starting some stuff
As `root` 'enable' icecast2/liquidsoap/nginx, this is to
make sure these applications start when the server reboots.
```bash
sudo systemctl enable liquidsoap
sudo systemctl enable nginx
sudo systemctl enable icecast2
```
And start them:
```bash
sudo systemctl start icecast2
sudo systemctl start liquidsoap
```
Reload & start nginx:
```bash
systemctl reload nginx
sudo systemctl start nginx
```
### 6. Run the webif and IRC bot:
As `radio`, issue the following command:
```bash
python3 run webdev
```
Run it in `screen` or `tux` to keep it up, or write a systemd unit file for it.
### 7. Generate HTTPs certificate
```bash
certbot --nginx
```
Pick "Yes" for redirects.
## Command list
```text
- !np - current song
- !tune - upvote song
- !boo - downvote song
- !request - search and queue a song by title
- !dj+ - add a YouTube ID to the radiostream
- !dj- - remove a YouTube ID
- !ban+ - ban a YouTube ID and/or nickname
- !ban- - unban a YouTube ID and/or nickname
- !skip - skips current song
- !listeners - show current amount of listeners
- !queue - show queued up music
- !queue_user - queue a random song by user
- !search - search for a title
- !stats - stats
```
