Create sourcehut paste in Emacs

Paste is a sourcehut service like GitHub’s Gist. I wrote a function utilizing hut to create a paste in Emacs:

(defun yejun/paste-region-or-buffer (&optional p)
  (interactive "P")
  (let ((filename (read-string "Enter filename: " (buffer-name)))
        (output-buffer " *paste-output*")
        (public (if p " --visibility public" "")))
     (if (use-region-p) (region-beginning) (point-min))
     (if (use-region-p) (region-end) (point-max))
     (concat "hut paste create --name \"" filename "\"" public)
    (with-current-buffer output-buffer
      (goto-char (point-max))
      (forward-line -1)
      (kill-new (thing-at-point 'line)))
    (kill-buffer output-buffer)))

When calling the function, you will be prompted for a filename, by default, buffer-name is pre-filled for convenience. After creating the paste, the URL is copied to the clipboard.

There are two advices on giving a filename:

  • Give a meaningful filename: currently you cannot search paste by content, so a meaningful filename makes search easier.
  • Give a filename extension for code highlighting: see this paste for details.

The default visiblity is unlisted, using C-u to create a public paste, for Doom Emacs users, that’s SPC u.
