Xdebug is finally nearing version 2 and the only really important thing missing is a good and simple client that can speak the DBGp to interact with Xdebug . As I have no clue myself about GUI programming, I am hereby asking for your help to write a simple GUI application (QT/KDE/GTK/Gnome) that can do this.
This GUI application should be as standalone as possible, run on Linux and implement the full DBGp specification, including setting breakpoints, seeing stack traces, inspecting variables and stepping through code. Editting scripts in the interface should not even be possible.
If you are interested, feel free to write me at either firstname.lastname@example.org or preferrably through the email@example.com mailinglist. I can provide all the help that you need with the protocol.
