Provide a simple way to investigate particularly large and complex data structures.

The best way to get started is to bind M-: to 'data-debug-eval-expression.

(global-set-key "\\M-:" 'data-debug-eval-expression)

If you write functions with complex output that need debugging, you can make them interactive with data-debug-show-stuff. For example:

(defun my-complex-output-fcn ()
  "Calculate something complicated at point, and return it." (interactive) ;; function not normally interactive (let ((stuff (do-stuff))) (when (called-interactively-p 'interactive) (data-debug-show-stuff stuff "myStuff")) stuff))
