Love ghidra but hate Java? If so, then this extension is for you!
Just load this extension, and Ghidra will see and be able to load any
scripts written in Scala. Just make sure their filename ends in
.scala and drop them into any ghidra_scripts directory.
Now with 100% less Java! This version is written natively in Scala. Thanks to Edward J. Schwartz for the original Java implementation! This version also uses Gradle to automatically download and package the Scala compiler with the plugin.
If you want to build the extension yourself, make sure you have
gradle installed, and then run
GHIDRA_INSTALL_DIR=/path/to/ghidra gradle buildExtension. If
all goes well, you should get a message like:

In this case, the file
dist/ghidra_9.1.2_PUBLIC_20200221_ghidra-scala-loader.zip
is the newly built extension.
Start Ghidra, and in the initial window (i.e., not the Code
Browser), open the File menu, and select Install Extensions.
Click the small plus icon in the top right of the window, and select
the extension zip file that you built above. This should add an
extension into the list, ScalaScriptProvider. Make sure the
checkbox is ticked, and click OK to close the window. Ghidra will
tell you that you need to restart to load the extension. Do so.
To make sure the extension loaded correctly, open the Code Browser,
and under the Window menu, select Script Manager. If all is well,
you should see a HelloWorld.scala script. Right click it, and
select Run. You should see the hello world message print out to the
Console.
