Hi David, You'd have to modify the GDB set breakpoint command to highlight the line at which a breakpoint occurs. The JDEE uses an Emacs feature called overlays (or extents in XEmacs) to color the lines. The JDEE's code for doing this is in the file jde-db.el. You could look at it for examples of how to implement breakpoint highlighting. The JDEE breakpoint command saves the line at which a breakpoint is set in a list of breakpoints. It colors the line green initially. If an application is running, it sends a set breakpoint command to the debugger and colors the line yellow to indicate that a set breakpoint command has been issued to the debugger. The JDEE also sets up a process I/O listener that detects responses from the debugger. If this listener receives a response from the debugger that a breakpoint has been set, it looks up the breakpoint in the list of breakpoints and if it finds it, it changes the color of the highlight to red to indicate that the breakpoint has been set. To summarize: green -> Emacs has been asked to set a breakpoint. yellow -> Emacs has sent the breakpoint request to the debugger red -> The debugger has confirmed that the breakpoint has been set. Hope this helps. Paul > or may be you are aware of some > hack for gdb to achive that? > I'm not aware of any breakpoint highlighting code for gdb. Paul
