I had to write yet another letter, so I digged into this and it's now working well enough for me. I made a few changes to the file (which I attach): - fixed bugs to the menu (export to pdf, open pdf), added "export to tex file" - put a default address "no address" instead of a blank line, otherwise compilation fails - moved the lco file input before the preamble, so that one can specify some additional information (like packages). (This may be questionable, don't hesitate to let me know.) I now have two questions: a technical one and a non-technical one. The technical one: I see that org-e-koma extends the latex exporter with some options: (org-export-define-derived-backend koma-letter e-latex :options-alist ((:closing "CLOSING" nil org-koma-letter-closing) (:from-address "FROM_ADDRESS" nil org-koma-letter-from-address newline) ... These options have 3 arguments instead of 4 in the definition of options in org-e-latex: :options-alist ((:date "DATE" nil org-e-latex-date-format t) (:latex-class "LATEX_CLASS" nil org-e-latex-default-class t) ... Is the missing argument the one that lets EXPORT_OPTIONS specify if some parts can be omitted for subtree export? Or is it something different? The non-technical question: I understand this exporter is just a proof of concept, but it is working quite well for me, and I'm ready to help tweaking this. If I do further modifications, should I send them to the list? Thanks, Alan
