Hi, I'm finally able to announce the release of rudebug, a debugging front-end for ruby-debug and other debugging libraries for Ruby. It is based on Glade and Ruby-GNOME2. It has support for stepping, you can type code into a code shell and instantly see the results. The source code which is being executed is displayed as well. There is syntax highlighting everywhere. You can browse the current context in a fairly powerful way through the object browser. You can also reference the object that is selected in the object browser in the code shell. You can debug locally as well as remotely. More information is available on the project home page. (Including a more detailed project description, install guide, use guide and explanation of the implementation.)

It should probably have been released earlier. I hope it is still useful to the Ruby community. Comments and feedback are highly welcome. Thanks for your attention! Kind regards, Florian Gross
