Javascript function naming.

Feb 7, 2013 at 7:43 PM
I must say, I like Clearscript alot. Kudos.

Is there a way to specify what the exposed method's javascript function name is gonna be? I know jurassic solves it by annotations on methods. I cant stand beginning my C# methods with a lowercase character just because javascript's function should start with a lowercase. :)

Is there a way to hide non-private method from being accessible from javascript? I use javascript to populate objects and afterwards (back in c#) collect relevant data and results and use them. I wanna disable access from javascript to some of these public methods. Trying to keep the javascript interface as clean and straight forward as possible.
(Again - Jurassic does it with annotations.)

Hi Klator,

Thanks for the kind words!

ClearScript currently does not have explicit support for method hiding or renaming. One way to achieve the desired effect might be to create a forwarding wrapper that exposes precisely the interface you want:
public class MyObject
    public void SomeMethod() { }
    public void HiddenMethod() { }

public class MyObjectForScript
    private readonly MyObject _target;
    public MyObjectForScript(MyObject target) { _target = target; }

    public void someMethod() { _target.SomeMethod(); }

var myObject = new MyObject();
engine.AddHostObject("myObject", new MyObjectForScript(myObject));
Of course, this might be tedious if you're exposing a large interface, and you still have to break your C# naming conventions in the wrapper. We'll definitely consider other solutions. Stay tuned!

Yeah, I thought about that.

Just feels like an awful lot of boilerplate code just to get that functionality.
I hoped you guys had a solution that ive missed somewhere.

An other way would be using interfaces, but I think dont think that would work. (2 interfaces: one for internal, one for external/javascript)

Hmmm, back to the drawing table.
Anyway, it doesnt stop me from using Clearscript, worst case scenario is that there might be some undocumented functions, I guess.

Thanks anyway, looking forward to future releases.

We are tracking this issue here.

ClearScript 5.1 is now available!

It includes the following new features for customizing your script interfaces:
  • ScriptEngine.AddRestrictedHostObject() lets you expose a host object so that script code can only access the members of one of its base classes or interfaces.
  • NoScriptAccessAttribute allows you to hide public type members from script code.
  • ScriptMemberAttribute lets you expose a type member to script code under a different name, and to limit fields and properties to read-only access from script code.
Please check out the updated ClearScript Library Reference here.

I was just going to ask for this also! LOL ;)

You guys are doing a great job! I just love the thought of being able to include various scripting models - especially various JS engines - into my .NET apps. Just for fun (for now). I'm building a JavaScript server similar to Node (but much different), by using .NET as a wrapper instead (why? why not; because I can). ;) I figure there's always Mono to help make it cross-platform later on, which is why I like the V8 engine that's included.

Hi jamesnw. We appreciate your kind words, and would love to get feedback about using ClearScript on the server!
