Example

// Initialize a context
using (JavascriptContext context = new JavascriptContext()) {

    // Setting external parameters for the context
    context.SetParameter("console", new SystemConsole());
    context.SetParameter("message", "Hello World !");
    context.SetParameter("number", 1);

    // Script
    string script = @"
        var i;
        for (i = 0; i < 5; i++)
            console.Print(message + ' (' + i + ')');
        number += i;
    ";

    // Running the script
    context.Run(script);

    // Getting a parameter
    Console.WriteLine("number: " + context.GetParameter("number"));
}

Redistribution

Noesis.Javascript.dll needs the Microsoft C Runtime Libraries.

If you don't include the correct version of the runtime libraries when you redistribute Noesis.Javascript.dll then you will get errors when loading the DLL on some users machines. (Many, but not all users will already have it.)

Targets: .NET Framework 4.5

Building from Source

Open the .sln file in Visual Studio and build. I've been working using Visual Studio 2017, but 2015 will probably work too.

The following warnings are expected:

• warning LNK4248: unresolved typeref token (0100003F) for 'v8.internal.Object'; image may not run

• warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "C:\Users\oliver\Documents\GitHub\Javascript.Net\x64\Release\JavaScript.Net.dll", "AMD64". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project.

Running Tests

The unit tests are standard Visual Studio - run them using the GUI.

Nuget

Old versions have been published as Noesis.JavaScript.

Publishing a newer version is a work in progress.

Internationalization

??? buildv8.bat turns off internationalization when invoking gyp to avoid the need to distribute the (large) ICU DLLs and data file.
