Answer 1

I use the following for compilation. It keeps the compilation buffer if there are warnings or errors, and buries it otherwise (after 1 second).

(defun bury-compile-buffer-if-successful (buffer string)
 "Bury a compilation buffer if succeeded without warnings "
 (when (and
         (buffer-live-p buffer)
         (string-match "compilation" (buffer-name buffer))
         (string-match "finished" string)
         (not
          (with-current-buffer buffer
            (goto-char (point-min))
            (search-forward "warning" nil t))))
    (run-with-timer 1 nil
                    (lambda (buf)
                      (bury-buffer buf)
                      (switch-to-prev-buffer (get-buffer-window buf) 'kill))
                    buffer)))
(add-hook 'compilation-finish-functions 'bury-compile-buffer-if-successful)

jpkotta, it does work most of the times. Sometimes, even if there is a warning, it doesn't switch to compilation buffer. So I made a change to your form & it does work now:

(defun bury-compile-buffer-if-successful (buffer string)
  "Bury a compilation buffer if succeeded without warnings "
  (if (and
       (string-match "compilation" (buffer-name buffer))
       (string-match "finished" string)
       (not
        (with-current-buffer buffer
          **(goto-char 1)**
          (search-forward "warning" nil t))))
      (run-with-timer 1 nil
                      (lambda (buf)
                        (bury-buffer buf)
                        (switch-to-prev-buffer (get-buffer-window buf) 'kill))
                      buffer)))
(add-hook 'compilation-finish-functions 'bury-compile-buffer-if-successful)
