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.

visit-source.el is an utility Emacs package to quickly go to a file at point (under cursor). I bind (keymap-global-set "H-RET" #'visit-sourse) and can quickly go to files with line precision from anywhere, including log outputs.

At work I work with Terraform, so need to edit quite a lot of tf files in GNU Emacs. There's no built-in terraform-ts-mode Emacs package and I don't want to install regexp-based terraform-mode package

Existing terraform-ts-mode is this: kgrotel/terraform-ts-mode, which claims being experimental. So it's a good opportunity to learn how to create major modes using Tree Sitter and on <2026-05-05 Tue> I built my own with Claude Code.

Installation: put terraform-ts-mode.el to load-path.

Usage:

(use-package terraform-ts-mode :ensure nil
  :init
  (add-to-list 'major-mode-remap-alist '(terraform-mode . terraform-ts-mode)))

With this knowledge, the next step is [TK: try mickeynp/combobulate package].
