###gServ may be used as a standalone HTTP server to serve static content as well as REST resources written as Groovy scripts ##Requirements Java 1.6+ on the PATH

##Install Copy the contents of dist folder on GitHub to a local folder. Add that folder to your PATH.

##Verify installation type 'gserv' at the prompt

This should print the gServ options to the console.

    prompt> gserv -s /public -p 12000
    

GServ may be used to serve static content along with dynamic REST resources

    prompt> gserv -s /public -r Math.groovy -p 12000

    [Resource("/math"){
        get "/", {
            write "text/plain", "Welcome to our GServ Math example"
        }
    get "/:num1/:num2/:operation", { num1, num2, operation ->
        def ans = 0
        def msg = ""
        switch ( operation ){
            case "add" : ans = (num1 as int) + (num2 as int);
            case "subtract" : ans = (num1 as int) - (num2 as int);
            case "multiply" : ans = (num1 as int) * (num2 as int);
            case "divide" : ans = (num1 as double) / (num2 as double);
                msg = "$operation($num1, $num2) = $ans"
            default:
                msg = "Operation: $operation is not supported";
        }
        write "text/plain",  msg
    }
