How to find my javascript function in Jint in C#?

I wrote code below 

static void Main(string[] args)
    {
        var engine = new Engine();
        var file = File.ReadAllText(@"...\Desktop\beautify.js");
        var final = file + Environment.NewLine + "(function () {return js_beautify('var a = 2;');})();";
        var exec = engine.Execute(final);
        var r = exec.GetCompletionValue().ToString();
        Console.WriteLine(r);
        Console.Read();

    }

but the Jint show error

Jint.Runtime.JavaScriptException: 'js_beautify is not defined'

Can anyone help me how to register external js libraries like beautify.js and then call functions of them in Jint ?

Solution

  • It should be

     var engine = new Engine().Execute("var global = {};").Execute(content);
 var js_beautify = engine.Execute("global.js_beautify").GetCompletionValue();
 var result = engine.Invoke(js_beautify, "var a = 2;").AsString();
