Copy buffer-name with easy-kill

· back

easy-kill Emacs package allows killing multiple things, switching between them on the fly. I use it to quickly grab the buffer-file-name (full path or file name only), using {M-w b}.

github
leoliu/easy-kill

Keybindings:

{M-w} without active region
copy current line, same as {x y} in meow-normal-mode
{M-w C-w} without active region
kill current line, same as {x s} in meow-normal-mode
{M-w b}
copy current full path to buffer-file-name
{M-w b 0}
copy current buffer-file-name
{M-w b -}
copy current directory

On <2026-06-04 Thu> I added {M-w B} to copy current buffer-name, useful to paste into Claude Code (running under ghostel for me).

Here's the configuration block: 

(use-package easy-kill
  :config
  (keymap-global-set "<remap> <kill-ring-save>" #'easy-kill)
  (defun easy-kill-on-buffer-name (_n)
    "Get current `buffer-name'."
    (if (easy-kill-get mark)
        (easy-kill-echo "Not supported in `easy-mark'")
      (easy-kill-adjust-candidate 'buffer-name (buffer-name))))
  (add-to-list 'easy-kill-alist '(?B buffer-name)))
  1. Define function easy-kill-on-buffer-name.
  2. Add binding to 'easy-kill-alist.
