Examples

Say hello to earth

hello = {
    var WORLD : "world"

    doc "Run hello with to $WORLD"

    exec """
        echo hello $WORLD
    """
}
run { hello }

Say hello to mars Note that the script below is identical to the example above, except for the "run" portion.

hello = {
    var WORLD : "world"

    doc "Run hello with to $WORLD"

    exec """
        echo hello $WORLD
    """
}
run { hello.using(WORLD: "mars") }
