How to script the java debugger command-line tool (jdb)?

Question

How can I drive the debugging session with some scripting language like ruby? Is there any easier options than using Expect or some similar module with a scripting language?

Answer 1

Check out jdiscript; it's a thin scripting frontend for the JDI that can be used with Java, JRuby, or any other jvm language.

Answer 2

You may be able to use JRuby to drive your own debugger via the JPDA API.
