Cross platform GUI debugger for Ruby

By Peter Cooper / July 17, 2006


Mr. Guid is a Ruby GUI Debugger by 'Mitchell'. It uses GTK+ so it's cross platform (Windows, Linux, OS X) and it can even work remotely over a network. Otherwise, it has all the features that the standard Ruby debugger has, just in GUI form.

    This is Mitchell, author of Mr. Guid. Unfortunately, there are still some issues in the Windows version and threads locking up. I would welcome any assistance on the issue.

    Thanks for the recognition :)

    Vladimir -

    I haven't tried it myself, but it seems to be very well thought out!

    Hi. what about radrails? could you debug your code with it?

  5. mitchell says:

    It's not a matter of fixing a bug, it's a matter of how sockets are handled in Windows. I couldn't find a workaround, and a very astute developer I worked had no success either. See
