org-export-latex-final-hook not working

[Giacomo M]

Dear all,

I am using emacs with this configuration file:

#+BEGIN_SRC emacs-lisp
(setq load-path (append (file-expand-wildcards "~/.emacs.d/elpa/*") load-path))
(require 'org)
(require 'org-ref)
(require 'ox-extra)
(ox-extras-activate '(ignore-headlines))
(defun remove-orgmode-latex-labels ()
   "Remove labels generated by org-mode"
   (interactive)
   (let ((case-fold-search nil))
    (goto-char 1)
    (replace-regexp "\\\\label{sec.*}" "")
    )
)
(add-hook 'org-export-latex-final-hook 'remove-orgmode-latex-labels)
#+END_SRC

to load the latest orgmode from melpa and install a hook to remove 
unwanted section labels on latex export.

If you open/create any .org file and export it to latex buffer or file, 
the hook function is not called. if I visit the buffer and call 
remove-orgmode-latex-labels, section labels are removed.

Where is the mistake?

Thanks,

Giacomo

There's no such hook.

See org-export-filter-body-functions and
org-export-filter-final-output-functions.

Thanks.
I found an example for html by Rasmus on the mailing list. Just adapting 
it to my case works.

#+BEGIN_SRC emacs-lisp
(defun jackjackk/org-latex-remove-section-labels (string backend info)
   "Remove section labels generated by org-mode"
     (when (and (org-export-derived-backend-p backend 'latex)
                (string-match "\\\\label{sec:.*}" string))
       (replace-regexp-in-string "\\\\label{sec:.*}" "" string)))

(add-to-list 'org-export-filter-final-output-functions
              'jackjackk/org-latex-remove-section-labels)
#+END_SRC

Best,

Giacomo

FWIW, I suggest

  (when (org-export-derived-backend-p backend 'latex)
    (replace-regexp-in-string "\\\\label{sec:.*?}" "" string)))

A greedy regexp may give you surprises.

There is no such thing as `org-export-latex-final-hook'. You may want to
use `org-export-filter-final-output-functions'.
