28 ;; OVERVIEW
29 ;;
30 ;; org-export-generic is basically a simple translation system that
31 ;; knows how to parse at least most of a .org buffer and then add
32 ;; various formatting prefixes before and after each section type. It
33 ;; does this by examining a property list stored in org-generic-alist.
34 ;; You can dynamically add propety lists of your own using the
35 ;; org-set-generic-type function:
36 ;;
37 ;; (org-set-generic-type
38 ;; "really-basic-text"
39 ;; '(:file-suffix ".txt"
40 ;; :key-binding ?R
41 ;;
42 ;; :title-format "=== %s ===\n"
43 ;; :body-header-section-numbers t
44 ;; :body-header-section-number-format "%s) "
45 ;; :body-section-header-prefix "\n"
46 ;; :body-section-header-suffix "\n"
47 ;; :body-line-format " %s\n"
48 ;; :body-line-wrap 75
49 ;; ))
50 ;;
51 ;; Note: Upper case key-bindings are reserved for your use. Lower
52 ;; case key bindings may conflict with future export-generic
53 ;; publications.
54 ;;
55 ;; Then run org-export (ctrl-c ctrl-e) and select generic or run
56 ;; org-export-generic. You'll then be prompted with a list of export
57 ;; types to choose from which will include your new type assigned to
58 ;; the key "r".

62 ;; TODO (non-ordered)
63 ;; * handle function references
64 ;; * handle other types of multi-complex-listy-things to do
65 ;; ideas: (t ?- "%s" ?-)
66 ;; * handle indent specifiers better
67 ;; ideas: (4 ?\ "%s")
68 ;; * need flag to remove indents from body text
69 ;; * handle links
70 ;; * handle internationalization strings better
71 ;; * date/author/etc needs improvment (internationalization too)
72 ;; * allow specifying of section ordering
73 ;; ideas: :ordering ("header" "toc" "body" "footer")
74 ;; ^ matches current hard coded ordering
75 ;; * err, actually *do* a footer
76 ;; * deal with usage of org globals
77 ;; *** should we even consider them, or let the per-section specifiers do it
78 ;; *** answer: remove; mostly removed now
79 ;; * deal with interactive support for picking a export specifier label
80 ;; * char specifiers that need extra length because of formatting
81 ;; idea: (?- 4) for 4-longer
82 ;; * centering specifier
83 ;; idea: ('center " -- %s -- ")
84 ;; * remove more of the unneeded export-to-ascii copy code
85 ;; * tags
86 ;; *** supported now, but need separate format per tag
87 ;; *** allow different open/closing prefixes
88 ;; * properties
89 ;; * drawers
90 ;; * oh my
91 ;; * optmization (many plist extracts should be in (let) vars
92 ;; * define defcustom spec for the specifier list
