  • Scope of object properties & methods

    - by Anish
    In the article Show love to the object literal, it's said: When we have several scripts in a page, the global variables & functions will get overwritten if their name repeats. One solution is to make the variables as properties & functions as methods of an object, and access them via the object name. But will this prevent the issue of variables getting into the global namespace? <script> var movie = { name: "a", trailer: function(){ //code } }; </script> In the above code which elements gets added to the global namespace? a) Just the object name - movie b) Object name as well as the properties and methods inside it – movie, movie.name, movie.trailer()

  • Intellisense on custom types in Iron Python

    - by Anish Patel
    Hi everybody, I'm just starting to play around with IronPython and am having a hard time using it with custom types created in C#. I can get IronPython to load in assemblies from C# classes, but I'm struggling without the help of intellisense. If I have a class in C# as defined below, how can I make it so that IronPython will be able to see the methods/properties that are available in it? public class Person { public string Name { get; set; } public int Age{ get; set; } public double Weight{ get; set; } public double Height { get; set; } public double CalculateBMI() { return Weight/Math.Pow(Height, 2); } } In Iron python I'd instance a Person object as follows: newPerson = Person() newPerson.Name = 'John' newPerson.Age = 25 newPerson.Weight = 75 newPerson.Height = 1.70 newPerson.CalculateBMI() The thing that is annoying me is that I want to be able to say newPerson = Person() And then be able to see all the methods and properties associated with the person object whenever I type: newPerson. Anyone have any ideas if this can be done?
