I am using JRuby, but I am often calling scripts from other scripts, which means that when I have StackTraces from the Java caller, not all the StackTraceElements are coming from the initial calling class.

For example, if I have the following code in Ruby:

public
  def compute()
    retur 10
  end

I have the following StackTraceElement:

• declaringClass: RUBY
• methodName: compute
• fileName: <script>
• lineNumber: 3

I would like to get somewhere the name of my script, is it possible to get it in JRuby?

I am creating the script by:

    RubyRuntimeAdapter adapter = JavaEmbedUtils.newRuntimeAdapter();
    IRubyObject io = adapter.eval(runtime, <scriptContent>);

• 1 Wouldn't accessing the constant __FILE__ do what you want? Why do you need a StackTraceElement? – user1934428 Commented Mar 27 at 11:11
• I created a framework which encapsulate the usage of scripts in Groovy, Ruby, Javascript or Python (with JRuby, Rhino, or Jython)? In this framework I allow the user to navigate in the StackTrace in the script – Hervé Girod Commented Apr 2 at 14:16

I understood how to do it. Rather than:

IRubyObject io = adapter.eval(runtime, <scriptContent>);

I have to do:

JavaEmbedUtils.EvalUnit evalUnit = adapter.parse(runtime, <scriptContent>, <file name>, 1);
IRubyObject io = evalUnit.run();
