[Bashdb-remake] RFC Emacs interaction in Debugging Bash, Python, Ruby, Make

[R. B. <ro...@pa...>]

What things do people find most helpful in debugging from emacs? What
things in general are lacking? (Of course, I'm mostly interested in
the languages cited above and improving debugging interaction with
those, but other information could be helpful as well.)

One thing I notice regarding edebug which seems different than gud
debugging is that it sets up (I guess) a recursive edit on the program
begin debugged so that it can bind keys to debug functions like step,
next, and so on. Do people generally find it useful when debugging to
set the program read only so that it can't be modified while
debugging? Or is this an annoyance?

For Emacs Lisp code, I find C-x C-e helpful and use that a lot. For
these other programming languages that could be bound to eval using
the debugger. (And if not debugging, it might fall back to running the
expression in a comint shell buffer).
