;;; Commentary:
;; NOV == Yet Another EPub Reader 
;; Package nov.el is an alternative to Emacspeak's built-in EPub
;; reader.
;; This module speech-enables nov.el
;; In addition, opening an epub using nov results in
;; directory-specific settings being loaded from file
;; @var{emacspeak-speak-directory-settings} ---
;;  That file can set book-specific settings such as speech-rate and
;; punctuation-mode among others.

;;; Code:

;;   Required modules:

(eval-when-compile (require 'cl-lib))
(cl-declaim  (optimize  (safety 0) (speed 3)))
(require 'emacspeak-preamble)

;;;  Interactive Commands:

(cl-loop
 for f in 
 '(
   nov-browse-url
   nov-display-metadata
   nov-goto-toc
   nov-next-document
   nov-previous-document
   )
 do
 (eval
  `(defadvice ,f (after emacspeak pre act comp)
     "speak."
     (when (ems-interactive-p)
       (emacspeak-icon 'open-object)
       (emacspeak-speak-buffer)))))

(cl-loop
 for f in
 '(nov-scroll-up  nov-scroll-down)
 do
 (eval
  `(defadvice ,f (after emacspeak pre act comp)
     "Speak the next screenful."
     (when (ems-interactive-p)
       (emacspeak-icon 'scroll)
       (dtk-speak (emacspeak-get-window-contents))))))

;;; Mode Hook:

(defun emacspeak-nov-mode-hook ()
  "Load directory-specific speech settings."
  (cl-declare (special emacspeak-speak-directory-settings))
  (emacspeak-speak-load-directory-settings default-directory))

(add-hook 'nov-mode-hook #'emacspeak-nov-mode-hook)

(provide 'emacspeak-nov)
