I've seen that Greg has just entered a JIRA ticket for this.
Is needed some comment inside ?
If you think the ticket requires additional detail, feel free to add
some.
Rather than creating a new macro language, why not simply take
advantage of the existing scripting facilities in the JVM?
Right, so maybe a first test (or better, Tutorial) could be for an
Applet, via Javascript (in the Browser), ok ?
You don't need to run an application in the browser to script it via
JavaScript. A JavaScript scripting engine comes with Java 6 and above.
