Hi,

I copied that to my init.el file
> (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 ()

>> 	 (tmp-file "/tmp/my.html")
>> 	 (html (rcd-asciidoctor asciidoc)))
>>      (with-temp-file tmp-file
>>        (insert html))))


and starting emacs it shows this:

Debugger entered--Lisp error: (void-variable SECS)
   (run-with-timer SECS REPEAT FUNCTION &rest ARGS)
   load-with-code-conversion("/home/gfp/.config/emacs/init.el" 
"/home/gfp/.config/emacs/init.el" t t)
   load("/home/gfp/.config/emacs/init" noerror nomessage)
   startup--load-user-init-file(#f(compiled-function () #<bytecode

0x4d12c0e0e44348b>) t)
   command-line()
   normal-top-level()


I have also installed

>> 

and
> Tab Reloader (page auto refresh) – Get this Extension for 🦊 Firefox (en-US):
>> https://addons.mozilla.org/en-US/firefox/addon/tab-reloader/
>> 

the only missing is: web-server.


Kind regards

Gottfried
