Hi, I'm trying to define a filter function local to a file for the final output filter, but it doesn't seem to work.
This works: #+BEGIN_SRC emacs-lisp :exports results :results none (defun hiho (s backend info) (message "HiHo") s) (add-to-list 'org-export-filter-final-output-functions 'hiho) #+END_SRC But it destructively changes 'org-export-filter-final-output-functions Trying to define a file local filter doesn't work: #+BIND: org-export-filter-final-output-functions (hiho) #+BEGIN_SRC emacs-lisp :exports results :results none (defun hiho (s backend info) (message "HiHo") s) #+END_SRC This is developed based on the explanations in the org manual here: https://orgmode.org/manual/Advanced-Export-Configuration.html#Filters What am I doing wrong? -- Orm
