RIM has updated their Ripple Emulator this week with a quick refresh. It now allows you to easily set the services to start and stop with chrome and other simplifications to avoid the command line. This new refresh also adds emulation for the new APIs delivered in the latest BlackBerry WebWorks SDK releases. RIM has also enhanced support for the Apache Cordova emulation for those of you using it. Check out the details on their DevBlog or more on the Ripple download page.
Also worth noting is that RIM has updated the BlackBerry WebWorks SDK to expose the ability for creating your own extensions. This allows you to add your own native APIs that RIM has not exposed yet in the same way RIM does. If you wanted access to some more native functions from WebWorks or want to contribute your own APIs in the future to the community check out the details here.
Personally I am loving RIM’s focus on solid HTML5 WebWorks development for BlackBerry 10.
