||
;;; 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',
|
||
;; - 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').
|
||
;;
|
||
;; The following variables works differently from the main LaTeX class
|
||
;; - AUTHOR: Default to user-full-name but may be disabled.
|
||
;; (See also `org-koma-letter-author'),
|
||
;; - EMAIL: Same as AUTHOR. (see also `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 need an appropriate association in `org-latex-classes' in order
|
||
;; to use the KOMA Scrlttr2 class. By default, a sparse scrlttr2
|
||
;; class is provided: "default-koma-letter". 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'.
|
||
;;
|
||

|
||

|
