Use unicode symbol to display org-mode checkboxes
With the help of prettify-symbols-mode, you can make your Emacs
displaying org-mode checkboxes as a real Unicode symbols, instead of a
boring text, put this to your org-mode-hook:
(add-hook 'org-mode-hook (lambda ()
"Beautify Org Checkbox Symbol"
(push '("[ ]" . "☐") prettify-symbols-alist)
(push '("[X]" . "☑" ) prettify-symbols-alist)
(push '("[-]" . "❍" ) prettify-symbols-alist)
(prettify-symbols-mode)))
You can also use font-lock-add-keywords to add a different style for
checked boxes, like what I did below, adding a strike-through style:
(defface org-checkbox-done-text
'((t (:foreground "#71696A" :strike-through t)))
"Face for the text part of a checked org-mode checkbox.")
(font-lock-add-keywords
'org-mode
`(("^[ \t]*\\(?:[-+*]\\|[0-9]+[).]\\)[ \t]+\\(\\(?:\\[@\\(?:start:\\)?[0-9]+\\][ \t]*\\)?\\[\\(?:X\\|\\([0-9]+\\)/\\2\\)\\][^\n]*\n\\)"
1 'org-checkbox-done-text prepend))
'append)
Here’s the result:
