Using Script.swift with swift-sh

When you want a script, you typically want it in a single file. With usual setup using Swift Package Manager to interact with external libraries, you would end up a directory with Package.swift, which is bit much as a script.

By using swift-sh, you only have to take care of a single Swift file for your script, which makes your Swift script as portable as possible.

Examples

Source Script

echo.swift

 
Script()
    .exec(#"echo "testing""#)
    .stdout()
