Show line number on error

Say that emacs throws some error that I don't understand. Or maybe the error says "Symbol's value as variable is void: modes", but there are many occurrences of the symbol modes in my code, so I need some context. Can Emacs be configured to mention…

Clearing/removing all breakpoints

Is there a mechanism for clearing all breakpoints (remove instrumentation en masse) so as to avoid the need to manually run eval-defun on each instrumented function's definition?

Edebug REPL / IELM

I toggled edebug-defun on a function I'm studying. Once the debugger kicks in, how can I fire a REPL with access to the symbols being debugged? I know it's possible to evaluate commands with e in edebug-mode, but that's on the minibuffer and not as…

If I have a buffer with the contents (defun foo() (interactive) (bar) (message "foo")) (defun bar() (interactive) (message "bar")) ...and call eval-buffer with edebug-all-defs set to t, then both calls to foo and bar directly throw me…

What tools can help make the emacs debug output more readable?

I was expecting to find tools I can use to to e.g. prettify the stack trace, or e.g. show all variables that are bound at each level of the stack trace as you navigate, but haven't found anything. Do any tools to improve the debugging experience…

Something setqs desktop-dirname to nil after my "init.el" is loaded. I want to track down the offending code. Just before the end of "init.el", desktop-dirname is correctly set. I checked run-hooks by giving advise to it, but the variable was found…

How do I insert a breakpoint so that edebug starts only when that point is reached

I want to instrument a function so that edebug gets control when that point is reached. I can insert (edebug) in the code, however, unless the function is instrumented with edebug (C-u M-S-x), that will be interpreted as (debug), which I don't…
