75 Newsticker provides a newsticker for Emacs. A newsticker is a thing
76 that asynchronously retrieves headlines from a list of news sites,
77 prepares these headlines for reading, and allows for loading the
78 corresponding articles in a web browser.
81 Headlines consist of a title and (possibly) a small description. They
82 are contained in "RSS" (RDF Site Summary) or "Atom" files. Newsticker
83 should work with the following RSS formats:
86 @item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or
87 @uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}),
88 @item RSS 0.92 (see @uref{http://backend.userland.com/rss092}),
89 @item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec}
90 @item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}),
93 as well as the following Atom formats:
96 @uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}).
99 That makes Newsticker.el an "Atom aggregator, "RSS reader", or "RSS
102 Newsticker provides several commands for reading headlines, navigating
103 through them, marking them as read/unread, hiding old headlines etc.
104 Headlines can be displayed as plain text or as rendered HTML.
106 Headlines can be displayed in the echo area, either scrolling like
107 messages in a stock-quote ticker, or just changing.
109 Newsticker allows for automatic processing of headlines by providing
110 hooks and (sample) functions for automatically downloading images and
111 enclosed files (as delivered by podcasts, e.g.).
114 Here are screen shots of the @uref{newsticker-1.7.png, version 1.7
115 (current version)} and some older screen shots:
116 @uref{newsticker-1.6.png, version 1.6},
117 @uref{newsticker-1.5.png, version 1.5},
118 @uref{newsticker-1.4.png, version 1.4}
119 @uref{newsticker-1.3.png, version 1.3},
120 @uref{newsticker-1.0.png, version 1.0}.
124 @chapter Requirements
126 Newsticker can be used with
127 @uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version
128 21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It
129 requires an XML-parser (@file{xml.el}) which is part of GNU Emacs. If
130 you are using XEmacs you want to get the @file{net-utils} package
131 which contains @file{xml.el} for XEmacs.
133 Newsticker requires a program which can retrieve files via http and
134 prints them to stdout. By default Newsticker will use
135 @uref{http://www.gnu.org/software/wget/wget.html, wget} for this task.
139 @chapter Installation
141 As Newsticker is part of GNU Emacs there is no need to perform any
142 installation steps in order to use Newsticker.
144 However, if you are using imenu, which allows for navigating with the
145 help of a menu, you should add the following to your Emacs startup file
149 (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index)
157 @findex newsticker-show-news
158 The command @code{newsticker-show-news} will display all available
159 headlines in a special buffer, called @samp{*newsticker*}. It will
160 also start the asynchronous download of headlines. The modeline in
161 the @samp{*newsticker*} buffer informs whenever new headlines have
162 arrived. Clicking mouse-button 2 or pressing RET in this buffer on a
163 headline will call @code{browse-url} to load the corresponding news
164 story in your favourite web browser.
166 @findex newsticker-start-ticker
167 @findex newsticker-stop-ticker
168 The scrolling, or flashing of headlines in the echo area, can be
169 started with the command @code{newsticker-start-ticker}. It can be
170 stopped with @code{newsticker-stop-ticker}.
172 @findex newsticker-start
173 @findex newsticker-stop
174 If you just want to start the periodic download of headlines use the
175 command @code{newsticker-start}. Calling @code{newsticker-stop} will
176 stop the periodic download, but will call
177 @code{newsticker-stop-ticker} as well.
180 @chapter Configuration
182 All Newsticker options are customizable, i.e. they can be changed with
183 Emacs customization methods: Call the command
184 @code{customize-group} and enter @samp{newsticker} for the customization
187 All Newsticker options have reasonable default values, so that in most
188 cases it is not necessary to customize settings before starting Newsticker
191 Newsticker options are organized in the following groups.
196 @code{newsticker-feed} contains options that define which news
197 feeds are retrieved and how this is done.
201 @vindex newsticker-url-list
202 @code{newsticker-url-list} defines the list of headlines which are
205 @vindex newsticker-retrieval-interval
206 @code{newsticker-retrieval-interval} defines how often headlines
211 @code{newsticker-headline-processing} contains options that define
212 how the retrieved headlines are processed.
216 @vindex newsticker-keep-obsolete-items
217 @code{newsticker-keep-obsolete-items} decides whether unread
218 headlines that have been removed from the feed are kept in the
223 @code{newsticker-layout} contains options that define how the
224 buffer for reading news headlines is formatted.
228 @vindex newsticker-heading-format
229 @code{newsticker-item-format} defines how the title of a headline
234 @code{newsticker-ticker} contains options that define how headlines
235 are shown in the echo area.
239 @vindex newsticker-display-interval
240 @vindex newsticker-scroll-smoothly
241 @code{newsticker-display-interval} and
242 @code{newsticker-scroll-smoothly} define how headlines are shown in
247 @code{newsticker-hooks} contains options for hooking other Emacs
248 commands to newsticker functions.
251 @vindex newsticker-new-item-functions
252 @code{newsticker-new-item-functions} allows for automatic
253 processing of headlines. See `newsticker-download-images', and
254 `newsticker-download-enclosures' for sample functions.
258 @code{newsticker-miscellaneous} contains other Newsticker options.
262 Please have a look at the customization buffers for the complete list
268 This newsticker is designed do its job silently in the background
269 without disturbing you. However, it is probably impossible to prevent
270 such a tool from slightly attenuating your Editor's responsiveness
271 every once in a while.
273 Byte-compiling newsticker.el is recommended.
