72 Newsticker provides a newsticker for Emacs. A newsticker is a thing
73 that asynchronously retrieves headlines from a list of news sites,
74 prepares these headlines for reading, and allows for loading the
75 corresponding articles in a web browser.
78 Headlines consist of a title and (possibly) a small description. They
79 are contained in ``RSS'' (RDF Site Summary) or ``Atom'' files. Newsticker
80 works with the following RSS formats:
83 @item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or
84 @uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}),
85 @item RSS 0.92 (see @uref{http://backend.userland.com/rss092}),
86 @item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec}
87 @item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}),
90 as well as the following Atom formats:
93 @uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}).
96 That makes Newsticker.el an ``Atom aggregator'', ``RSS reader'', ``Feed
97 aggregator'', or ``Feed reader''.
99 Newsticker provides several commands for reading headlines, navigating
100 through them, marking them as read/unread, hiding old headlines etc.
101 Headlines can be displayed as plain text or as rendered HTML.
103 Headlines can be displayed in the echo area, either scrolling like
104 messages in a stock-quote ticker, or just changing.
106 Newsticker allows for automatic processing of headlines by providing
107 hooks and (sample) functions for automatically downloading images and
108 enclosed files (as delivered by, e.g., podcasts).
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}.
123 @chapter Requirements
125 Newsticker can be used with
126 @uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version
127 21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It
128 requires an XML-parser (@file{xml.el}), which is part of GNU Emacs. If
129 you are using XEmacs you want to get the @file{net-utils} package
130 which contains @file{xml.el} for XEmacs.
132 Newsticker retrieves headlines either via Emacs's built-in retrieval
133 functions, by an arbitrary external program that retrieves files via
134 http and prints them to stdout (like
135 @uref{http://www.gnu.org/software/wget/wget.html, wget}, or -- on a
136 per feed basis -- via an arbitrary Lisp command.
140 @chapter Installation
142 As Newsticker is part of GNU Emacs there is no need to perform any
143 installation steps in order to use Newsticker.
145 However, if you are using imenu, which allows for navigating with the
146 help of a menu, you should add the following to your Emacs startup file
150 (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index)
158 @findex newsticker-show-news
159 The command @code{newsticker-show-news} will display all available
160 headlines. It will also start the asynchronous download of headlines.
162 You can choose between two different frontends for reading headlines:
164 @item Newsticker's @emph{treeview} uses separate windows for the
165 feeds (in tree form), a list of headlines for the current feed, and
166 the content of the current headline. Feeds can be placed into groups,
167 which themselves can be placed in groups and so on.
168 @item Newsticker's @emph{plainview} displays all headlines in a
169 single buffer, called @samp{*newsticker*}. The modeline in the
170 @samp{*newsticker*} buffer informs you whenever new headlines have
173 In both views clicking mouse-button 2 or pressing RET on a headline
174 will call @code{browse-url} to load the corresponding news story in
175 your favorite web browser.
177 @findex newsticker-start-ticker
178 @findex newsticker-stop-ticker
179 The scrolling, or flashing of headlines in the echo area, can be
180 started with the command @code{newsticker-start-ticker}. It can be
181 stopped with @code{newsticker-stop-ticker}.
183 @findex newsticker-start
184 @findex newsticker-stop
185 If you just want to start the periodic download of headlines use the
186 command @code{newsticker-start}. Calling @code{newsticker-stop} will
187 stop the periodic download, but will call
188 @code{newsticker-stop-ticker} as well.
191 @chapter Configuration
193 All Newsticker options are customizable, i.e. they can be changed with
194 Emacs customization methods. Call the command
195 @code{customize-group} and enter @samp{newsticker} for the customization
198 All Newsticker options have reasonable default values, so that in most
199 cases it is not necessary to customize settings before starting Newsticker
202 The following list shows the available groups of newsticker options
203 and some of the most important options.
208 @code{newsticker-retrieval} contains options that define which news
209 feeds are retrieved and how this is done.
213 @vindex newsticker-url-list

217 @vindex newsticker-retrieval-method

219 retrieved. This is either done using Emacs's built-in download
220 capabilities or using an external tool.

228 @code{newsticker-headline-processing} contains options that define
