If not, see . ;;; Commentary: ;; ;; This library implements a KOMA Scrlttr2 back-end, derived from the ;; LaTeX one. ;; ;; Depending on the desired output format, three commands are provided ;; for export: `org-koma-letter-export-as-latex' (temporary buffer), ;; `org-koma-letter-export-to-latex' ("tex" file) and ;; `org-koma-letter-export-to-pdf' ("pdf" file). ;; ;; On top of buffer keywords supported by `latex' back-end (see ;; `org-latex-options-alist'), this back-end introduces the following ;; keywords: ;; - "CLOSING" (see `org-koma-letter-closing'), ;; - "FROM_ADDRESS" (see `org-koma-letter-from-address'), ;; - "LCO" (see `org-koma-letter-class-option-file'), ;; - "OPENING" (see `org-koma-letter-opening'), ;; - "PHONE_NUMBER" (see `org-koma-letter-phone-number'), ;; - "SIGNATURE" (see `org-koma-letter-signature') ;; - "PLACE" (see `org-koma-letter-place') ;; - and "TO_ADDRESS". If unspecified this is set to "\mbox{}". ;; ;; TO_ADDRESS and FROM_ADDRESS can also be specified using heading ;; with the special tags specified in ;; `org-koma-letter-special-tags-in-letter', namely "to" and "from". ;; LaTeX line breaks are not necessary if using these headings. If ;; both a headline and a keyword specify a to or from address the ;; value is determined in accordance with ;; `org-koma-letter-prefer-special-headings'. ;; ;; A number of OPTIONS settings can be set to change which contents is ;; exported. ;; - backaddress (see `org-koma-letter-use-backaddress') ;; - foldmarks (see `org-koma-letter-use-foldmarks') ;; - phone (see `org-koma-letter-use-phone') ;; - email (see `org-koma-letter-use-email') ;; - place (see `org-koma-letter-use-place') ;; - subject, a list of format options ;; (see `org-koma-letter-subject-format') ;; - after-closing-order, a list of the ordering of headings with ;; special tags after closing (see ;; `org-koma-letter-special-tags-after-closing') ;; - after-letter-order, as above, but after the end of the letter ;; (see `org-koma-letter-special-tags-after-letter'). ;; ;; Note, some formatting depends on whether the variables has been set ;; in the buffer. For instance, the email is inserted after LCO ;; files, if changed in the letter. ;; ;; The following variables works differently from the main LaTeX class ;; - "AUTHOR": default to user-full-name but may be disabled. (see org-koma-letter-author), ;; - "EMAIL": same as AUTHOR, (see org-koma-letter-email), ;; ;; Headlines are in general ignored. However, headlines with special ;; tags can be used for specified contents like postscript (ps), ;; carbon copy (cc), enclosures (encl) and code to be inserted after ;; \end{letter} (after_letter). Specials tags are defined in ;; `org-koma-letter-special-tags-after-closing' and ;; `org-koma-letter-special-tags-after-letter'. Currently members of ;; `org-koma-letter-special-tags-after-closing' used as macros and the ;; content of the headline is the argument. ;; ;; Headlines with two and from may also be used rather than the ;; keyword approach described above. If both a keyword and a headline ;; with information is present precedence is determined by ;; `org-koma-letter-prefer-special-headings'. ;; ;; You will need to add an appropriate association in ;; `org-latex-classes' in order to use the KOMA Scrlttr2 class. ;; The easiest way to do this is by adding ;; ;; (eval-after-load "ox-koma-letter" ;; '(org-koma-letter-plug-into-ox)) ;; ;; to your init file. This will add a sparse scrlttr2 class and ;; set it as the default `org-koma-latex-default-class'. You can also ;; add you own letter class. For instance: ;; ;; (add-to-list 'org-latex-classes ;; '("my-letter" ;; "\\documentclass\[% ;; DIV=14, ;; fontsize=12pt, ;; parskip=half, ;; subject=titled, ;; backaddress=false, ;; fromalign=left, ;; fromemail=true, ;; fromphone=true\]\{scrlttr2\} ;; \[DEFAULT-PACKAGES] ;; \[PACKAGES] ;; \[EXTRA]")) ;; ;; Then, in your Org document, be sure to require the proper class ;; with: ;; ;; #+LATEX_CLASS: my-letter ;; ;; Or by setting `org-koma-letter-default-class'. ;; You may possibly have to load (LaTeX) Babel as well, e.g., by adding ;; it to `org-latex-packages-alist', ;; ;; (add-to-list 'org-latex-packages-alist '("AUTO" "babel" nil)) ;;; Code: (require 'ox-latex) ;;; User-Configurable Variables (defgroup org-export-koma-letter nil "Options for exporting to KOMA scrlttr2 class in LaTeX export." :tag "Org Koma-Letter" :group 'org-export) (defcustom org-koma-letter-class-option-file "NF" "Letter Class Option File." :group 'org-export-koma-letter :type 'string) (defcustom org-koma-letter-author 'user-full-name "The sender's name.
