Kill Buffer DWIM
When you call
kill-buffer Emacs prompts you for which buffer you'd like to
kill. The default choice is the current buffer, which is good because 9 times
out of 10 that's the buffer I want to kill, but confirming that choice every
time is tedious.
Emacs has a wonderful convention of "do what I mean" (DWIM) commands, versions of
commands which do one thing if a condition is met and another if it isn't. My
kill-buffer should kill the current buffer by default, and if it is
prefixed by the universal argument I should be prompted for which buffer I'd
like to kill. The best of both worlds I think.
(defun kill-buffer-dwim (&optional u-arg) "Call kill-current-buffer, with C-u: call kill-buffer." (interactive "P") (if u-arg (call-interactively 'kill-buffer) (call-interactively 'kill-current-buffer)))
