NAME

r4 - the Radio4000 CLI

USAGE

r4 download <channel-slug>
r4 <command> help
r4 -h, --help
r4 -v, --version

DESCRIPTION

r4 is a program for interacting with Radio4000.

INSTALLATION

For downloads to work, make sure [youtube-dl](https://github.com/rg3/youtube-dl/) and ffmpeg installed on your system.

Prefer npm (over yarn, as the yarn linking is not global with nvm).

From npm

• npm i -g r4, to install r4 globally
• r4 should now be available as a command in your terminal/shell

From gitlab directly

To install r4 as a global npm package from a gitab repository do:

• npm i -g gitlab:internet4000/r4

DEVELOPMENT

1. git clone [e-mail]:internet4000/r4.git
2. cd r4
3. npm link

Linking makes r4 use your local copy. If you you are changing the path or adding a new binary, remember to run npm unlink and npm link in the project.

Lint scripts and run tests with npm run test. To format scripts, run npm run prettier.

FURTHER NOTES

If you have jq installed, you can actually download the tracks of a channel with this one-liner:

curl https://api.radio4000.com/v1/channels/-JYZtdQfLSl6sUpyIJx6/tracks | jq -r '.[] | .url' | youtube-dl -ixa /dev/stdin --audio-format mp3

... if you don't have jq, but have python, try this:

curl https://api.radio4000.com/v1/channels/-JYZtdQfLSl6sUpyIJx6/tracks | python -m json.tool | grep -oP '"url": "\K(.+)",' | youtube-dl -a /dev/stdin --extract-audio --audio-format mp3
