  • Hello reubenbond!

    We currently have no plans to release ClearScript in binary form. Please see our comments in this thread.

    That said, there's nothing stopping someone else from doing so :-)

    Description

    ClearScript is a library that makes it easy to add scripting to your .NET applications. It currently supports JavaScript (via V8 and JScript) and VBScript.

    Features

    • Simple usage; create a script engine, add your objects and/or types, run scripts
    • Support for several script engines: Google's V8, Microsoft's JScript and VBScript
    • Exposed resources require no modification, decoration, or special coding of any kind
    • Scripts get simple access to most of the features of exposed objects and types:
      • Methods, properties, fields, events
      • (Objects) Indexers, extension methods, conversion operators, explicitly implemented interfaces
      • (Types) Constructors, nested types
    • Full support for generic types and methods, including C#-like type inference and explicit type arguments
    • Scripts can invoke methods with output parameters, optional parameters, and parameter arrays
    • Script delegates enable callbacks into script code
    • Support for exposing all the types defined in one or more assemblies in one step
    • Optional support for importing types and assemblies from script code
    • The host can invoke script functions and access script objects directly
    • Full support for script debugging

    Examples

    using System;
    using Microsoft.ClearScript.V8;
    
    // create a script engineusing (var engine = new V8ScriptEngine())
    {
        // expose a host type

  • Thanks both, and also congratulations to jamesnw.
    I will give a look to V8.NET asap, it could be what we need.
    I looked at VroomJS too, but it does not compile with recent V8 API (3.17), probably it need a bit reworking after last API changes...

    Well, thank you and good work to all.

  • VroomJS only seems to compile for mono, and has Linux libraries (links libv8.so). It also doesn't seem to support compiling the V8 source as 64-bit.

  • I did not tried to compile 64 bit version, another problem.
    I tried to substitute libvroomjs.cproj project with a libvroomjs.vcxproj using same C++ sources. The .NET project should be linked with v8-xx.dll, but before this I should solve the V8 API change (and some other minor) problem(s).
    For the moment I cannot investigate more, perhaps in a next future.

    Comments: We have reproduced this issue and are investigating the root cause. The trigger appears to be that your program sets up two global properties whose names differ only in case: "StudentInfo" and "studentInfo". You can work around the bug by renaming one of them. This issue appears to be specific to JScriptEngine.

    Description

    ClearScript is a library that makes it easy to add scripting to your .NET applications. It currently supports JavaScript (via V8 and JScript) and VBScript.

    Features

    • Simple usage; create a script engine, add your objects and/or types, run scripts
    • Support for several script engines: Google's V8, Microsoft's JScript and VBScript
    • Exposed resources require no modification, decoration, or special coding of any kind
    • Scripts get simple access to most of the features of exposed objects and types:
      • Methods, properties, fields, events
      • (Objects) Indexers, extension methods, conversion operators, explicitly implemented interfaces
      • (Types) Constructors, nested types
    • Full support for generic types and methods, including C#-like type inference and explicit type arguments
    • Scripts can invoke methods with output parameters, optional parameters, and parameter arrays
    • Script delegates enable callbacks into script code
    • Support for exposing all the types defined in one or more assemblies in one step
    • Optional support for importing types and assemblies from script code
    • The host can invoke script functions and access script objects directly
    • Full support for script debugging

    Examples

    using System;
    using Microsoft.ClearScript;

    Comments: Hello! Thanks for your question. Because ClearScript relies on components that use COM registration (JScript/VBScript) and just-in-time compilation (Google V8), it is not compatible with WinRT. A pure .NET interpreter such as [Jint](https://jint.codeplex.com/) might be closer to what you're looking for. By the way, please use the [Discussions](https://clearscript.codeplex.com/discussions) area for asking questions. Thank you!
