;;; Commentary:
;;
;; This file adds support for `prettify-symbols-mode' in Org buffers.
;; To use, call M-x org-prettify-mode or put
;;
;; (add-hook 'org-mode-hook #'org-prettify-mode)
;;
;; in your configuration file.
;;; Code:
(require 'org)
(defvar-local org-pretty-alist '(("*" . ?•))
"An alist of symbols to prettify, see `prettify-symbols-alist'.
Whether the symbol actually gets prettified is controlled by
`org-pretty-compose-p', which see.")
(defun org-pretty-compose-p (start end match)
"Return non-nil if the symbol between START and END is to be prettified.
MATCH is the string match. See also
`prettify-symbols-compose-predicate'."
(if (string= match "*")
;; Prettify asterisks in headings.
(and (org-match-line org-outline-regexp-bol)
(< end (match-end 0)))
;; Else rely on the default function.
(funcall #'prettify-symbols-default-compose-p start end match)))
