Re: [solved] Re: To switch state of line not working

[Jean Louis <bugs@gnu.support>]

Shorter version:
n
(defun rcd-check (&optional check-in check-out)
  "Replace matches of CHECK-IN with CHECK-OUT in a line.

It is useful to toggle [ ] to [✔]"
  (interactive)
  (let* ((start (line-beginning-position))
	 (end (line-end-position))
	 (line (buffer-substring start end))
	 (check-in (or check-in "[ ]"))
	 (check-out (or check-out "[✔]")))
    (cond ((string-match (regexp-quote check-in) line) 
	   (replace-regexp (regexp-quote check-in) check-out nil start end))
	  ((string-match (regexp-quote check-out) line)
	   (replace-regexp (regexp-quote check-out) check-in nil start end)))))

1. [✔] Something
2. [✔] Done
3. [ ] To be done

(defun rcd-highlight-list (list)
  "Uses LIST to highlight strings in buffer."
  (hi-lock-mode)
  (let* ((list (delete "" list))
	(highlights hi-lock-face-defaults))
    (while list
      (highlight-regexp (regexp-quote (pop list)) (pop highlights)))))

(rcd-highlight-list '("[ ]" "[✔]"))
