[PRL] Official Google Research Blog: Under the Hood of App Inventor for Android

[Mitchell Wand]

FYI:


> We recently announced our App Inventor for Android<http://googleresearch.blogspot.com/2009/07/app-inventor-for-android.html>project on the Google Research Blog. That blog entry was long on vision but
> short on technological details--details which we think would be of interest
> to our readers.
>
> Of particular interest is our use of Scheme<http://groups.csail.mit.edu/mac/projects/scheme/>.
> Part of our development environment is a visual programming language similar
> to Scratch <http://scratch.mit.edu/>. The visual language provides a
> drag-and-drop interface for assembling procedures and event handlers that
> manipulate high-level components of Android-based phones. The components are
> similar to the ones in the recently announced Simple<http://google-opensource.blogspot.com/2009/07/programming-made-simple.html>;
> in fact, the code bases share an ancestor.
>
> We parse the visual programming language into an S-expression<http://en.wikipedia.org/wiki/S-expression>intermediate language, which is a domain-specific language expressed as a
> set of Scheme macros, along with a Scheme runtime library.
