;;; Code:

(defun trinket-bol (&optional pos)
  "Return position of first character on line containing POS.
If POS is omitted, use position of point.

Do not move point."
  (save-excursion
    (let ((pos (or pos (point))))
      (goto-char pos)
      (line-beginning-position))))

(defun trinket-eol (&optional pos)
  "Return position of last character on line containing POS.
If POS is omitted, use position of point.

Do not move point."
  (save-excursion
    (let ((pos (or pos (point))))
      (goto-char pos)
      (line-end-position))))
