26 ;;; Commentary:
28 ;; This module allows to create and change entries in an Org-mode
29 ;; file triggered by items in an RSS feed. The basic functionality is
30 ;; geared toward simply adding new items found in a feed as outline nodes
31 ;; to an Org file. Using hooks, arbitrary actions can be triggered for
32 ;; new or changed items.
34 ;; Selecting feeds and target locations
35 ;; ------------------------------------
37 ;; This module is configured through a single variable, `org-feed-alist'.
38 ;; Here is an example, using a notes/tasks feed from reQall.com.
40 ;; (setq org-feed-alist
41 ;; '(("ReQall"
42 ;; "http://www.reqall.com/user/feeds/rss/a1b2c3....."
43 ;; "~/org/feeds.org" "ReQall Entries")
45 ;; With this setup, the command `M-x org-feed-update-all' will
46 ;; collect new entries in the feed at the given URL and create
47 ;; entries as subheadings under the "ReQall Entries" heading in the
48 ;; file "~/org-feeds.org". Each feed should normally have its own
49 ;; heading - however see the `:drawer' parameter.
51 ;; Besides these standard elements that need to be specified for each
52 ;; feed, keyword-value pairs can set additional options. For example,
53 ;; to de-select transitional entries with a title containing
55 ;; "reQall is typing what you said",
57 ;; you could use the `:filter' argument:
59 ;; (setq org-feed-alist
60 ;; '(("ReQall"
61 ;; "http://www.reqall.com/user/feeds/rss/a1b2c3....."
62 ;; "~/org/feeds.org" "ReQall Entries"
63 ;; :filter my-reqall-filter)))
65 ;; (defun my-reqall-filter (e)
66 ;; (if (string-match "reQall is typing what you said"
67 ;; (plist-get e :title))
68 ;; nil
69 ;; e))
71 ;; See the docstring for `org-feed-alist' for more details.
74 ;; Keeping track of previously added entries
75 ;; -----------------------------------------
77 ;; Since Org allows you to delete, archive, or move outline nodes,
78 ;; org-feed.el needs to keep track of which feed items have been handled
79 ;; before, so that they will not be handled again. For this, org-feed.el
80 ;; stores information in a special drawer, FEEDSTATUS, under the heading
81 ;; that received the input of the feed. You should add FEEDSTATUS
82 ;; to your list of drawers in the files that receive feed input:
84 ;; #+DRAWERS: PROPERTIES LOGBOOK FEEDSTATUS
86 ;; Acknowledgments
87 ;; ----------------
89 ;; org-feed.el is based on ideas by Brad Bozarth who implemented a
90 ;; similar mechanism using shell and awk scripts.

103 (defgroup org-feed nil
104 "Options concerning RSS feeds as inputs for Org files."
105 :tag "Org ID"
106 :group 'org)
108 (defcustom org-feed-alist nil
109 "Alist specifying RSS feeds that should create inputs for Org.
110 Each entry in this list specified an RSS feed tat should be queried
111 to create inbox items in Org. Each entry is a list with the following items:
113 name a custom name for this feed
114 URL the Feed URL
115 file the target Org file where entries should be listed
116 headline the headline under which entries should be listed
118 Additional arguments can be given using keyword-value pairs. Many of these
119 specify functions that receive one or a list of \"entries\" as their single
120 argument. An entry is a property list that describes a feed item. The
121 property list has properties for each field in the item, for example `:title'
122 for the `<title>' field and `:pubDate' for the publication date. In addition,
123 it contains the following properties:
125 `:item-full-text' the full text in the <item> tag
126 `:guid-permalink' t when the guid property is a permalink
128 Here are the keyword-value pair allows in `org-feed-alist'.
130 :drawer drawer-name
131 The name of the drawer for storing feed information. The default is
132 \"FEEDSTATUS\". Using different drawers for different feeds allows
133 several feeds to target the same inbox heading.
135 :filter filter-function
136 A function to select interesting entries in the feed. It gets a single
137 entry as parameter. It should return the entry if it is relevant, or
138 nil if it is not.
140 :template template-string
141 The default action on new items in the feed is to add them as children
142 under the headline for the feed. The template describes how the entry
143 should be formatted. If not given, it defaults to
144 `org-feed-default-template'.
146 :formatter formatter-function
147 Instead of relying on a template, you may specify a function to format
148 the outline node to be inserted as a child. This function gets passed
149 a property list describing a single feed item, and it should return a
150 string that is a properly formatted Org outline node of level 1.
152 :new-handler function
153 If adding new items as children to the outline is not what you want
154 to do with new items, define a handler function that is called with
155 a list of all new items in the feed, each one represented as a property
156 list. The handler should do what needs to be done, and org-feed will
157 mark all items given to this handler as \"handled\", i.e. they will not
158 be passed to this handler again in future readings of the feed.
159 When the handler is called, point will be at the feed headline.
161 :changed-handler function
162 This function gets passed a list of all entries that have been
163 handled before, but are now still in the feed and have *changed*
164 since last handled (as evidenced by a different sha1 hash).
165 When the handler is called, point will be at the feed headline.
167 :parse-feed function
168 This function gets passed a buffer, and should return a list of entries,
169 each being a property list containing the `:guid' and `:item-full-text'
170 keys. The default is `org-feed-parse-rss-feed'; `org-feed-parse-atom-feed'
171 is an alternative.
173 :parse-entry function
174 This function gets passed an entry as returned by the parse-feed
175 function, and should return the entry with interesting properties added.
176 The default is `org-feed-parse-rss-entry'; `org-feed-parse-atom-entry'
177 is an alternative."
