Instead of creating a break_foo_bar macro you instead make a break_foo_bar command file (let's say break_foo_bar.cmd) containing: break foo commands print x end break bar commands print y end When you want to run this, you type source break_foo_bar.cmd If you want, you should be able to maco-ize that: define break_foo_bar source break_foo_bar.cmd end and then have a macro

Preferably in some sort of scripting language. You don't really need a plug in. gdb has a a very flexible built-in macro language that allows you to write a lot of very useful scripts that can do all sorts of things. "flexible"?! gdb is a great debugger, but to say that the macro system is lacking is to make a gross understatement. e.g., http://article.gmane.org/gmane.comp.gdb.general/445: the following: define break_foo_bar break foo commands print x end break bar commands print y end end does not work because, apparently, the first "end" closes both "commands" and "define" and there is no file loaded at this time, so I get this error: .gdbinit:97: Error in sourced command file: No symbol table is loaded. Use the "file" command. Is there a way around this problem?

But I AFAIR the built-in macro language does not have bindings to any GUI widget library... Regards -- I've probably left my head... somewhere. Please wait untill I find it.

You don't really need a plug in. gdb has a a very flexible built-in macro language that allows you to write a lot of very useful scripts that can do all sorts of things. Google for gdb macro and you will find such interesting things as: http://www.ibm.com/developerworks/aix/library/au-gdb.html
