Thanks for the pointer. The DB Inspector is actually twofold: a tree 
list to navigate in the hierarchy of slots and then there is a need to 
display the data (or queues, stack,etc..) attahced to the slot. At that 
point this Ruby object pretty printer may well be very useful to me.

Both in fact !!
What I currently have in mind is the following:

- Use dRuby and a modified version of Hiroshi NAKAMURA remote debugger 
to drive the remote debugger through a proper API and get access to all 
the process variables, stack, threads,etc...

- And I'll use Open3 (or a conventional pipe may be enough) to catch the 
output (stdout, stderr) of the debugged process and show it in the 
FreeRIDE UI.
