Abstract: This specification describes technologies relating to software execution. A computing device includes a processor. An operating system includes an execution environment in which applications can execute computer-specific commands. A web-browser application includes a scripting environment for interpreting scripted modules. The web-browser application further includes a native environment in which native modules can execute computer-specific commands. The web-browser application further includes an interface between the scripting environment and the native environment. The interface includes functions to asynchronously pass data objects by value, from one of the scripting environment and the native environment, to the other of the scripting environment and the native environment.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for an extensible browser plugin interface. In one aspect, a method includes receiving, at a browser plugin interface, an interface request from a plugin, where the interface request includes an interface identifier string that identifies a particular interface; determining, using the interface identifier string, whether the particular interface is supported by the browser; and if it is determined that the particular interface is supported by the browser, returning to the plugin a virtual function table (vtable) of one or more functions, wherein the vtable is associated with the particular interface identified by the interface request.
