;;; Commentary:

;; Provides a minor mode for using the fixed-pitch face.  Allows users to use a
;; variable-pitch font as the default while still using fixed-pitch for code.

;;; Code:

(defun fixed-pitch-update-hooks (list)
  "Adds `fixed-pitch-mode' to every hook in LIST."
  (dolist (hook list)
    (add-hook hook 'fixed-pitch-mode)))

(defcustom fixed-pitch-whitelist-hooks '()
  "List of hooks that should activate `fixed-pitch-mode'."
  :type '(repeat symbol)
  :group 'fixed-pitch
  :set (lambda (var val)
         (set-default var val)
         (fixed-pitch-update-hooks val)))

;;;###autoload
(define-minor-mode fixed-pitch-mode
  "Use monospace typeface in the appropriate context."
  :lighter " fxd"
  (if fixed-pitch-mode
      (progn (buffer-face-set 'fixed-pitch))
    (buffer-face-set)))
