Hi, coming to Ruby from Java i’m lookin for a tool similar to = [http://cs.joensuu.fi/jeliot/index.php](http://cs.joensuu.fi/jeliot/index.php) which is for java only. Any tools available ? Thanks for any hints!! Regards, Gilbert ---

> Thanks for any hints!! > > Regards, Gilbert I’m afraid I don’t know of anything like that, but others may. Looking at the tool, do you actually find that at all useful? 🙂 It’s kind of fun, but does it help you to see what’s going on? I wonder if you’d be better off with a normal graphical debugger (Komodo, for Ruby, say.). They usually give much the same kind of information about the virtual machine’s states, but don’t act out an animated story of how those changes occur. ---

Komodo ain’t free. I’m looking for a free tool. Are there free graphical debuggers around for ruby ?! > They usually give much the same kind of information about the > virtual machine’s states, but don’t act out an animated story of how > those changes occur. working with eclipse, i know the benefits of a debugger, but the RDT plugins are not the same level as the JDT yet.

But if a flow tracer will do (shows all calls, returns, lines, exceptions etc, plus all locals and all params) then take a look at Ruby Bug Validator. ``` http://www.softwareverify.com/ruby/flow_tracer/index.html ``` Stephen ---

That looks pretty cool. Although, it is text based you can use the ruby tracer tool. Simply run “ruby -r tracer yourcode.rb” to see the textual output of what Ruby is doing. If I were to attempt making Jeliot for Ruby I would probably use this as a base. Cheers, Zev ---

I have no 299 bucks around 😉 Regards, Gilbert ---
