* ox-koma-letter.el (org-koma-letter-special-tags-after-closing): specials tags inserted after =\end{closing}=. * ox-koma-letter.el (org-koma-letter-special-tags): collect the special lists. * ox-koma-letter.el (org-koma-letter-headline): stores content in of headline if the first tag is special. Otherwise return content. * ox-koma-letter.el (org-koma-letter-special-content): holds special content temporarily. * ox-koma-letter.el (org-koma-letter--format-string-as-macro): format a string as a macro or don't. * ox-koma-letter.el (org-koma-letter-template): added support for the headings with special tags. The following example will now export a sensible manner. * my letter here's a letter * PS :ps: it's requires this patch * CC :cc: Nicolas, Viktor and Alan * ENCL :encl: many patches 1. this patch 2. another patch. * include patches :after_letter: \myspecialmacro \includepdf{pdf} Namely, content of ps, encl and cc headings will be exported after \closing{.} in the order prescribed by =`org-koma-letter-special-tags-after-closing'= as a (LaTeX) macro removing trailing and leading newlines. The macro is the same as the tag, althogh the case is determined by the special list. The concents of the =after_letter= heading will be inserted after =\end{letter}= and newlines are preserved.

;;; 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') and "TO_ADDRESS".
|
||
;;
|
||
;; You will need to add an appropriate association in
|
||
;; `org-latex-classes' in order to use the KOMA Scrlttr2 class. For
|
||
;; example, you can use the following code:
|
||
;;
|
||
;; (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 :
|
