28 ;; This file implements links to BBDB database entries from within Org.
29 ;; Org mode loads this module by default - if this is not what you want,
30 ;; configure the variable `org-modules'.
32 ;; It also implements an interface (based on Ivar Rummelhoff's
33 ;; bbdb-anniv.el) for those Org users, who do not use the diary
34 ;; but who do want to include the anniversaries stored in the BBDB
35 ;; into the org-agenda. If you already include the `diary' into the
36 ;; agenda, you might want to prefer to include the anniversaries in
37 ;; the diary using bbdb-anniv.el.
39 ;; Put the following in /somewhere/at/home/diary.org and make sure
40 ;; that this file is in `org-agenda-files'.
42 ;; %%(org-bbdb-anniversaries)
44 ;; For example my diary.org looks like:
47 ;; %%(org-bbdb-anniversaries)
50 ;; To add an anniversary to a BBDB record, press `C-o' in the record.
51 ;; You will be prompted for the field name, in this case it must be
52 ;; "anniversary". If this is the first time you are using this field,
53 ;; you need to confirm that it should be created.
55 ;; The format of an anniversary field stored in BBDB is the following
56 ;; (items in {} are optional):
58 ;; YYYY-MM-DD{ CLASS-OR-FORMAT-STRING}
59 ;; {\nYYYY-MM-DD CLASS-OR-FORMAT-STRING}...
61 ;; CLASS-OR-FORMAT-STRING is one of two things:
63 ;; - an identifier for a class of anniversaries (eg. birthday or
64 ;; wedding) from `org-bbdb-anniversary-format-alist' which then
65 ;; defines the format string for this class
66 ;; - the (format) string displayed in the diary.
68 ;; You can enter multiple anniversaries for a single BBDB record by
69 ;; separating them with a newline character. At the BBDB prompt for
70 ;; the field value, type `C-q C-j' to enter a newline between two
73 ;; If you omit the CLASS-OR-FORMAT-STRING entirely, it defaults to the
74 ;; value of `org-bbdb-default-anniversary-format' ("birthday" by
77 ;; The substitutions in the format string are (in order):
78 ;; - the name of the record containing this anniversary
79 ;; - the number of years
80 ;; - an ordinal suffix (st, nd, rd, th) for the year
82 ;; See the documentation of `org-bbdb-anniversary-format-alist' for
89 ;; 1998-03-12 %s created bbdb-anniv.el %d years ago
91 ;; From Org's agenda, you can use `C-c C-o' to jump to the BBDB
92 ;; link from which the entry at point originates.
