I have gone through gud.el and I understand interaction is accomplished by parsing gdb's output. Could you please confirm my understanding? There are 2 interfaces: the old one in gud.el uses the CLI output with annotations, the new one in gdb-mi.el uses the GDB/MI interface. > If so, why is this approach better than writing event handlers using gdb's scheme interpreter? Not sure what you mean by that. How would Emacs invoke the GDB's Guile interface? > The context for this question is that I'm writing a gdb client, not for emacs, that somehow resembles what gud does. So I wanted to know what gud does because it is widely used and it is known to work. You can look in gdb-mi.el to see the code which uses GDB/MI.
