scdlbot Usage in Telegram

Send /start or /help command to bot or refer directly to the help message.

Please report all bugs and issues and suggest your improvements to issues.

Supported sites and mainly used packages

scdlbot is standing on the shoulders of giants:

• Telegram Bot API: python-telegram-bot
• SoundCloud: scdl
• Bandcamp: bandcamp-dl
• YouTube, Yandex.Music, Mixcloud, and almost everything from this list: yt-dlp

Run your own scdlbot

Installation & Configuration

Requirements

Those should be available in your PATH:

• Python 3.10+ (pyenv and poetry are recommended)
• yt-dlp strongly recommended dependencies, including:
• FFmpeg 6.1+ (in your $PATH) (if not running on Heroku/Render)
  • yt-dlp patched builds are highly recommended
  • otherwise these fresh builds are recommended: Linux, macOS, Windows.
• Heroku CLI is recommended if you want to deploy to Heroku

Install / Update stable build from PyPI (recommended)

pip install --upgrade scdlbot

...or get latest unstable build from Git source repository

git clone https://github.com/gpchelkin/scdlbot.git
cd scdlbot
pip install --editable "./"

# or just install directly from Git with pip:
pip install "scdlbot @ git+https://github.com/gpchelkin/scdlbot.git@master"

Configure Bot

Download or copy configuration file sample and set up config environment variables in it:

# Skip if you've got Git source:
curl -o .env.sample https://raw.githubusercontent.com/gpchelkin/scdlbot/master/.env.sample

cp .env.sample .env
# Use your favourite editor. Sample config is self-documented:
nano .env

Telegram Bot Settings

Send the commands from respective filenames in telegram_settings dir to @BotFather, choose your bot and copy corresponding values in order to use the bot conveniently. Disable privacy mode if you want bot to read and check every message in group for links. Otherwise, it would work only for commands.

Running Locally or on Dedicated Server

Using Heroku Local

You will need Heroku CLI installed.

# Skip if you've got Git source:
curl -O https://raw.githubusercontent.com/gpchelkin/scdlbot/master/Procfile

# For long polling mode (if WEBHOOK_ENABLE="0"):
heroku local -e .env worker
# For webhook mode (if WEBHOOK_ENABLE="1"):
heroku local -e .env web

Using only Bash & Python

export $(grep -v '^#' .env | xargs)
python -m scdlbot
# or in one line:
env $(grep -v '^#' .env | xargs) python -m scdlbot

# If you've installed package into your system Python,
# you can also replace 'python -m scdlbot' with just 'scdlbot'
# If you use Windows, you _have_ to replace 'python -m scdlbot' with just 'scdlbot'.

Deploying to Heroku

Register on Heroku, press the Deploy button above and configure variables for deploying. When app is deployed you must set only one dyno working on "Resources" tab in your app settings depending on which way of getting updates you have chosen and set in config variables: worker for polling or web for webhook.

Manually

You can do the same as the button above but using Heroku CLI. Assuming you are in scdlbot Git repository directory:

# Log into Heroku:
heroku login
# Create app with Python 3 buildpack and set it for upcoming builds:
heroku create --buildpack heroku/python myscdlbot
#heroku buildpacks:set heroku/python --app=myscdlbot
# Add FFmpeg buildpack needed for youtube-dl & scdl:
heroku buildpacks:add --index 1 https://github.com/gpchelkin/heroku-buildpack-ffmpeg-latest.git --app=myscdlbot
# Set config vars automatically from your local .env file:
heroku plugins:install heroku-config
heroku config:push --file=.env --app=myscdlbot
# or set them manually like this:
heroku config:set TG_BOT_TOKEN="<TG_BOT_TOKEN>" TG_BOT_OWNER_CHAT_ID="<TG_BOT_OWNER_CHAT_ID>" ...
# Deploy app to Heroku:
#heroku git:remote --app=myscdlbot
git push heroku master

Then, if you want to use webhook, start web dyno and stop worker dyno:

heroku ps:scale web=1 worker=0
heroku ps:stop worker

If you want to use polling, start worker dyno and stop web dyno:

heroku ps:scale worker=1 web=0
heroku ps:stop web

Some useful commands:

# Attach to logs:
heroku logs -t
# Test run ffprobe
heroku run "ffprobe -version"

Deploying to Dokku

Use Dokku (your own Heroku) installed on your own server. App is tested and fully ready for deployment with polling (no webhook yet). https://github.com/dokku/dokku-letsencrypt

export DOKKU=<your_dokku_server>
scp .env $DOKKU:~
ssh $DOKKU
    export DOKKU=<your_dokku_server>
    dokku apps:create scdlbot
    dokku certs:generate scdlbot scdlbot.$DOKKU
    dokku config:set scdlbot $(cat .env | xargs)
    logout
git remote add dokku dokku@$DOKKU:scdlbot
git push dokku master
ssh $DOKKU
    dokku ps:scale scdlbot worker=1 web=0
    dokku ps:restart scdlbot
