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

[Jean Louis <bugs@gnu.support>]

This is now looking better in plain text:

(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 (or rcd-check-in-default "[ ]")))
	 (check-out (or check-out (or rcd-check-out-default "[✔]"))))
    (rcd-check-start)
    (save-excursion
      (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))))))

(defvar rcd-check-in-default "❰    ❱")
(defvar rcd-check-out-default "❰DONE❱")

(defun rcd-check-start ()
  "Insert variable `rcd-check-in-default' at the beginning of line."
  (interactive)
  (let* ((start (line-beginning-position))
	 (end (line-end-position))
	 (line (buffer-substring start end)))
    (when (and (not (string-match rcd-check-in-default line))
	       (not (string-match rcd-check-out-default line)))
      (save-excursion
	(goto-char start)
	(insert rcd-check-in-default " ")))))

Something to be done, yes.

then user invokes key on the line and gets:

❰    ❱ Something to be done, yes.

then again:

❰DONE❱ Something to be done, yes.

then again:

❰    ❱ Something to be done, yes.

To me that looks more visual than just [X]

❰    ❱ Donec a diam lectus. 
❰DONE❱ *Sed sit amet ipsum mauris.* 
❰DONE❱ Maecenas congue ligula ac quam viverra nec consectetur ante hendrerit.
❰    ❱ **Donec et mollis dolor**. 
❰    ❱ Praesent et diam eget libero egestas mattis sit amet vitae augue.
