Hi, html multipage output is fully working now in the org-export compliant way sketched by Ihor.
There is a small issue with org-export-as from ox.el: On my machine applying the :filter-final-output functions to the final output strings delete their :output-file Text Property. Below is a commented somewhat ugly fix just to show what was necessary to make it work. Maybe you have a better idea about how to change it. (let* ((output (or (org-export-data (plist-get info :parse-tree) info) ""))) (setq output (ensure-list output)) ;; we need to capture the :output-file properties as they ;; might get erased in the following filter stages. (let ((output-files (mapcar (lambda (o) (get-text-property 0 :output-file o)) output))) ;; Call citation export finalizer. (when (plist-get info :with-cite-processors) (setq output (mapcar (lambda (o) (org-cite-finalize-export o info)) output))) (let ((filters (plist-get info :filter-final-output))) ;; Call final-output filter and return result. (setq output (mapcar (lambda (o) (org-export-filter-apply-functions filters o info)) output))) ;; Apply org-export-info property and add back the ;; :output-file property. (setq output (cl-mapcar (lambda (o file) (org-add-props o nil :output-file file 'org-export-info info)) output output-files)) (if (length= output 1) (car output) output))) I will now review the code and test thoroughly before issuing merge requests and adding documentation but it looks good :-) -- Orm
