Setting up user defined texinfo headlines using outline-heading-alist

[Christopher Dimech]

I have followed your suggestion of using a function that sets 
outline-heading-alist
using texinfo-mode-hook. 

Have included the following setup (see code section), yet I am still getting 

@node uchapter-amcoh
@unnumbered 6 @ Ameliorating Waveform Coherency...

whenever I hit  "C-C @ C-t" (Hide Body).  Should I not get @usec and @usubsec
showing up as well?


-------- code --------

(defvar texinfo-hdlevels
      '( ("@chapter" . 2)
         ("@section" . 3)
         ("@subsection" . 4)
         ("@subsubsection" . 5)
         ;; --------------------------------------------------
         ("@unnumbered" . 2)
         ("@unnumberedsec" . 3)
         ("@unnumberedsubsec" . 4)
         ("@unnumberedsubsubsec" . 5)
         ;; --------------------------------------------------
         ("@appendix" . 2)
         ("@appendixsec" . 3)
         ("@appendixsubsec" . 4)
         ("@appendixsubsubsec" . 5)
         ;; --------------------------------------------------
         ("@majorheading" 2)
         ;; --------------------------------------------------
         ("@chapheading" 2)
         ("@heading" 3)
         ("@subheading" 4)
         ("@subsubheading" 5)
         ;; --------------------------------------------------
         ("@uchap" . 2)
         ("@usec" . 2)
         ("@usubsec" . 3)
         ("@usubsubsec" . 4) ))

(defun instate-texinfo-hdlevels ()
    (setq-local outline-heading-alist texinfo-hdlevels))

(defun texinfo-hdlevels-hook ()
  "todo"
  (add-hook 'texinfo-mode-hook #'instate-texinfo-hdlevels))

(defun outline-hooks ()
   "todo"
   (add-hook 'emacs-lisp-mode-hook #'outline-minor-mode)
   (add-hook 'texinfo-mode-hook #'outline-minor-mode) )

(outline-hooks)
(texinfo-hdlevels-hook)
