Usage

You could create shell script e.g. run in your project with code:

task_hello() { ## Print Hello World box
_box --p=1 --bg-green --bold --white "Hello World! $(_ansi --blue "🌍")"
}
url="https://raw.githubusercontent.com/webuni/shell-task-runner/master/run"if [ -n"$(command -v 'wget')" ];theneval"$(wget -qO- "$url")";elseeval"$(curl -s "$url")";fi

And then you just have to run this file sh ./run.
