71 Newsticker provides a newsticker for Emacs. A newsticker is a thing
72 that asynchronously retrieves headlines from a list of news sites,
73 prepares these headlines for reading, and allows for loading the
74 corresponding articles in a web browser.
77 Headlines consist of a title and (possibly) a small description. They
78 are contained in ``RSS'' (RDF Site Summary) or ``Atom'' files. Newsticker
79 works with the following RSS formats:
82 @item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or
83 @uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}),
84 @item RSS 0.92 (see @uref{http://backend.userland.com/rss092}),
85 @item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec}
86 @item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}),
89 as well as the following Atom formats:
92 @uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}).
95 That makes Newsticker.el an ``Atom aggregator'', ``RSS reader'', ``Feed
96 aggregator'', or ``Feed reader''.
98 Newsticker provides several commands for reading headlines, navigating
99 through them, marking them as read/unread, hiding old headlines etc.
100 Headlines can be displayed as plain text or as rendered HTML.
102 Headlines can be displayed in the echo area, either scrolling like
103 messages in a stock-quote ticker, or just changing.
105 Newsticker allows for automatic processing of headlines by providing
106 hooks and (sample) functions for automatically downloading images and
107 enclosed files (as delivered by, e.g., podcasts).
111 Here are screen shots of the @uref{newsticker-1.7.png, version 1.7
112 (current version)} and some older screen shots:

114 @uref{newsticker-1.5.png, version 1.5},
115 @uref{newsticker-1.4.png, version 1.4}
116 @uref{newsticker-1.3.png, version 1.3},
117 @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 retrieves headlines either via Emacs's built-in retrieval
132 functions, by an arbitrary external program that retrieves files via
133 http and prints them to stdout (like
134 @uref{http://www.gnu.org/software/wget/wget.html, wget}, or---on a
135 per feed basis---via an arbitrary Lisp command.
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. It will also start the asynchronous download of headlines.
161 You can choose between two different frontends for reading headlines:
163 @item Newsticker's @emph{treeview} uses separate windows for the
164 feeds (in tree form), a list of headlines for the current feed, and
165 the content of the current headline. Feeds can be placed into groups,
166 which themselves can be placed in groups and so on.
167 @item Newsticker's @emph{plainview} displays all headlines in a
168 single buffer, called @samp{*newsticker*}. The modeline in the
169 @samp{*newsticker*} buffer informs you whenever new headlines have
172 In both views clicking mouse-button 2 or pressing RET on a headline
173 will call @code{browse-url} to load the corresponding news story in
174 your favorite web browser.
176 @findex newsticker-start-ticker
177 @findex newsticker-stop-ticker
178 The scrolling, or flashing of headlines in the echo area, can be
179 started with the command @code{newsticker-start-ticker}. It can be
180 stopped with @code{newsticker-stop-ticker}.
182 @findex newsticker-start
183 @findex newsticker-stop
184 If you just want to start the periodic download of headlines use the
185 command @code{newsticker-start}. Calling @code{newsticker-stop} will
186 stop the periodic download, but will call
187 @code{newsticker-stop-ticker} as well.
190 @chapter Configuration
192 All Newsticker options are customizable, i.e., they can be changed with
193 Emacs customization methods. Call the command
194 @code{customize-group} and enter @samp{newsticker} for the customization
197 All Newsticker options have reasonable default values, so that in most
198 cases it is not necessary to customize settings before starting Newsticker
201 The following list shows the available groups of newsticker options
202 and some of the most important options.
207 @code{newsticker-retrieval} contains options that define which news
208 feeds are retrieved and how this is done.
212 @vindex newsticker-url-list

216 @vindex newsticker-retrieval-method
