V8 javascript wrapper for native windows dll

[jfc]

Does anyone have an example/howto on the following:

An existing windows dll that provides some functionality like char*
getMessage().

Create a V8 javascript wrapper to call this C/C++ function from
javascript.

Finally working this all work within Chrome.



Thanks,

Binding a DLL wrapper is identical to binding your own code to v8. 90% of the wrapping process is converting the application data to/from JS/C/C++. There is no special interface for wrapping DLLs. You simply create a binder function (or class, or family of functions) for the APIs exported by the DLL.

This is documented fairly well on the v8 home page (http://code.google.com/p/v8/) and is demonstrated in the code of several v8-based libraries, such as (but not limited to):

http://code.google.com/p/v8-juice/
http://code.google.com/p/cproxyv8/
http://code.google.com/p/v8cgi/

(An interesting URL pattern appears.)

AFAIK, this could only be made visible to Chrome if Chrome supports loading native plugins AND it exposes the JS engine to those plugins. i have no idea if it does either of those (still waiting on Chrome for Linux).
