Hi,

I put this in my init.el file concerning Asccidoc:


;;Asciidoctor
(defun string-to-file-force (string file)
   "Prints string into file, matters not if file exists. Return FILE as 
file name."
   (with-temp-file file
     (insert string))
   file)

(defun rcd-command-output-from-input (program input &rest args)
   "Return output string from PROGRAM with given INPUT string and 
optional ARGS."
   (let* ((output (with-temp-buffer
		   (insert input)
		   (apply #'call-process-region nil nil program t '(t nil) nil args)
		   (buffer-string))))
     output))

(defun rcd-asciidoctor (string &rest args)
   "Return HTML by using Asciidoctor markup STRING."
   (let ((asciidoctor (executable-find "asciidoctor")))
     (apply 'rcd-command-output-from-input "asciidoctor" string "-" args)))

(defun rcd-asciidoctor-preview ()
   "Preview asciidoctor"
   (interactive)
   (let ((asciidoctor (executable-find "asciidoctor")))
     (when asciidoctor
       (let* ((output (buffer-string))
	     (output (rcd-asciidoctor output))
	     (file (string-to-file-force output "asciidoctor-preview.html")))
	(browse-url file)))))

(require 'adoc-mode)
(define-key adoc-mode-map (kbd "C-c a") #'rcd-asciidoctor-preview)

;;Asciidoctor refresh output quickly
(run-with-timer SECS REPEAT FUNCTION &rest ARGS)
(run-with-timer 1 3 #'rcd-asciidoctor-preview-buffer-as-html)
(defun rcd-asciidoctor-preview-buffer-as-html ()
   "Convert asciidoctor to file `/tmp/my.html'"
   (let* ((asciidoc (buffer-string))
	 (tmp-file "/tmp/my.html")
	 (html (rcd-asciidoctor asciidoc)))
     (with-temp-file tmp-file
       (insert html))))


I put that in my init.el file concerning markdown-mode:


;; markdown for formatting text
(defun rcd-markdown (text &rest args)
   "Markdown processing"
   (let ((markdown (executable-find "markdown")))
     (cond (markdown
	   (cond (text
		  (apply 'rcd-command-output-from-input markdown (append (list text) 
args)))
		 (t ""))
	   (t (user-error "Command `markdown' not available"))))))

(defun rcd-markdown-preview ()
   "Preview Markdown."
   (interactive)
   (let* ((output (rcd-markdown (buffer-string)))
	 (file (concat (buffer-file-name) "-MD.html")))
     (with-temp-file file (insert output))
     (browse-url file)))
	
;;(define-key KEYMAP KEY DEF &optional REMOVE)
(require 'markdown-mode)
(define-key markdown-mode-map (kbd "C-c a") #'rcd-markdown-preview)



Kind regards

Gottfried
