There is currently no scripting language extension within Jalview, in part because a -scripting API has not been developed. +scripting API has not yet been developed.

It is, however, really easy to embed scripting -engines within Jalview. We haven't done it -with the Bean Scripting Framework, but the -code snippets below show you how to get going -with groovy. +engines like groovy. If groovy is detected on the +classpath, a new menu entry on the Desktop's Tools +menu will open the GroovyShell.

Getting Groovy...

-Finally, compile and run with the groovy-all-*.jar (get the jar -from the embedded directory within the +

-

-  
-  print Jalview.getAlignframes()[0].getTitle();
-

-Executing this will print the title of the first alignment loaded into Jalview.

TODO

Using Java class methods from Groovy is straightforward, but currently, there isn't a set of easy to use methods for the jalview objects. A Jalview Scripting API needs to be developed to make this easier.
