Protoeditor is a small KDE text editor developed for debugging scripts interactively. The goal is to provide a simple editor supporting a variety of debuggers for different languages.
Protoeditor uses katepart as the text editor, so all the functionalities of a good editor are present (highlights, folding marks, etc, etc, etc) wich makes the debug experience more pratical.
Besides the editor, it supports common debugger features like: steps, watches, backtrace, breakpoints, etc. Other features depend on what the debuggers supports.
