73 Newsticker provides a newsticker for Emacs. A newsticker is a thing
74 that asynchronously retrieves headlines from a list of news sites,
75 prepares these headlines for reading, and allows for loading the
76 corresponding articles in a web browser.
79 Headlines consist of a title and (possibly) a small description. They
80 are contained in "RSS" (RDF Site Summary) or "Atom" files. Newsticker
81 should work with the following RSS formats:
84 @item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or
85 @uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}),
86 @item RSS 0.92 (see @uref{http://backend.userland.com/rss092}),
87 @item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec}
88 @item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}),
91 as well as the following Atom formats:
94 @uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}).
97 That makes Newsticker.el an "Atom aggregator, "RSS reader", or "RSS
100 Newsticker provides several commands for reading headlines, navigating
101 through them, marking them as read/unread, hiding old headlines etc.
102 Headlines can be displayed as plain text or as rendered HTML.
104 Headlines can be displayed in the echo area, either scrolling like
105 messages in a stock-quote ticker, or just changing.
107 Newsticker allows for automatic processing of headlines by providing
108 hooks and (sample) functions for automatically downloading images and
109 enclosed files (as delivered by podcasts, e.g.).
112 Here are screen shots of the @uref{newsticker-1.7.png, version 1.7
113 (current version)} and some older screen shots:
114 @uref{newsticker-1.6.png, version 1.6},
115 @uref{newsticker-1.5.png, version 1.5},
116 @uref{newsticker-1.4.png, version 1.4}
117 @uref{newsticker-1.3.png, version 1.3},
118 @uref{newsticker-1.0.png, version 1.0}.
122 @chapter Requirements
124 Newsticker can be used with
125 @uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version
126 21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It
127 requires an XML-parser (@file{xml.el}) which is part of GNU Emacs. If
128 you are using XEmacs you want to get the @file{net-utils} package
129 which contains @file{xml.el} for XEmacs.
131 Newsticker requires a program which can retrieve files via http and
132 prints them to stdout. By default Newsticker will use
133 @uref{http://www.gnu.org/software/wget/wget.html, wget} for this task.
137 @chapter Installation
139 As Newsticker is part of GNU Emacs there is no need to perform any
140 installation steps in order to use Newsticker.
142 However, if you are using imenu, which allows for navigating with the
143 help of a menu, you should add the following to your Emacs startup file
147 (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index)
155 @findex newsticker-show-news
156 The command @code{newsticker-show-news} will display all available
157 headlines in a special buffer, called @samp{*newsticker*}. It will
158 also start the asynchronous download of headlines. The modeline in
159 the @samp{*newsticker*} buffer informs whenever new headlines have
160 arrived. Clicking mouse-button 2 or pressing RET in this buffer on a
161 headline will call @code{browse-url} to load the corresponding news
162 story in your favourite web browser.
164 @findex newsticker-start-ticker
165 @findex newsticker-stop-ticker
166 The scrolling, or flashing of headlines in the echo area, can be
167 started with the command @code{newsticker-start-ticker}. It can be
168 stopped with @code{newsticker-stop-ticker}.
170 @findex newsticker-start
171 @findex newsticker-stop
172 If you just want to start the periodic download of headlines use the
173 command @code{newsticker-start}. Calling @code{newsticker-stop} will
174 stop the periodic download, but will call
175 @code{newsticker-stop-ticker} as well.
178 @chapter Configuration
180 All Newsticker options are customizable, i.e. they can be changed with
181 Emacs customization methods: Call the command
182 @code{customize-group} and enter @samp{newsticker} for the customization
185 All Newsticker options have reasonable default values, so that in most
186 cases it is not necessary to customize settings before starting Newsticker
189 Newsticker options are organized in the following groups.
194 @code{newsticker-feed} contains options that define which news
195 feeds are retrieved and how this is done.
199 @vindex newsticker-url-list
200 @code{newsticker-url-list} defines the list of headlines which are
203 @vindex newsticker-retrieval-interval
204 @code{newsticker-retrieval-interval} defines how often headlines
209 @code{newsticker-headline-processing} contains options that define
210 how the retrieved headlines are processed.
214 @vindex newsticker-keep-obsolete-items
215 @code{newsticker-keep-obsolete-items} decides whether unread
216 headlines that have been removed from the feed are kept in the
221 @code{newsticker-layout} contains options that define how the
222 buffer for reading news headlines is formatted.
226 @vindex newsticker-heading-format
227 @code{newsticker-item-format} defines how the title of a headline
232 @code{newsticker-ticker} contains options that define how headlines
233 are shown in the echo area.
237 @vindex newsticker-display-interval
238 @vindex newsticker-scroll-smoothly
239 @code{newsticker-display-interval} and
240 @code{newsticker-scroll-smoothly} define how headlines are shown in
245 @code{newsticker-hooks} contains options for hooking other Emacs
246 commands to newsticker functions.
249 @vindex newsticker-new-item-functions
250 @code{newsticker-new-item-functions} allows for automatic
251 processing of headlines. See `newsticker-download-images', and
252 `newsticker-download-enclosures' for sample functions.
256 @code{newsticker-miscellaneous} contains other Newsticker options.
260 Please have a look at the customization buffers for the complete list
266 This newsticker is designed do its job silently in the background
267 without disturbing you. However, it is probably impossible to prevent
268 such a tool from slightly attenuating your Editor's responsiveness
269 every once in a while.
271 Byte-compiling newsticker.el is recommended.
