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.
77 Headlines consist of a title and (possibly) a small description. They
78 are contained in RSS (RDF Site Summary) files. Newsticker should work
79 with all RSS files that follow the @uref{http://purl.org/rss/1.0/spec,
80 RDF Rich Site Summary 1.0} specification. It should also work with
81 version 2.0 as well as other/older/alternative rss formats (like
82 0.9<something> or such). In other words: Newsticker is a ``RSS
83 reader'' or ``RSS aggregator''.
85 Newsticker provides several commands for reading headlines, navigating
86 through them, marking them as read/unread, hiding old headlines etc.
87 Headlines can be displayed as plain text or as rendered HTML.
89 Headlines can be displayed in the echo area, either scrolling like
90 messages in a stock-quote ticker, or just changing.
92 Newsticker allows for automatic processing of headlines by providing
93 hooks and (sample) functions for automatically downloading images and
94 enclosed files (as delivered by podcasts, e.g.).
97 Here are screen shots of the @uref{newsticker-1.7.png, version 1.7
98 (current version)} and some older screen shots:

100 @uref{newsticker-1.5.png, version 1.5},
101 @uref{newsticker-1.4.png, version 1.4}
102 @uref{newsticker-1.3.png, version 1.3},
103 @uref{newsticker-1.0.png, version 1.0}.
107 @chapter Requirements
109 Newsticker can be used with
110 @uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version
111 21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It
112 requires an XML-parser (@file{xml.el}) which is part of GNU Emacs. If
113 you are using XEmacs you want to get the @file{net-utils} package
114 which contains @file{xml.el} for XEmacs.
116 Newsticker requires a program which can retrieve files via http and
117 prints them to stdout. By default Newsticker will use
118 @uref{http://www.gnu.org/software/wget/wget.html, wget} for this task.
122 @chapter Installation
124 Place Newsticker in a directory where Emacs can find it. Add the
125 following line to your Emacs startup file (@file{~/.emacs}).
128 (add-to-list 'load-path "/path/to/newsticker/")
129 (autoload 'newsticker-start "newsticker" "Emacs Newsticker" t)
130 (autoload 'newsticker-show-news "newsticker" "Emacs Newsticker" t)
133 Newsticker-mode supports imenu. This allows for navigating with the
134 help of a menu. In order to use this feature you should also add the
138 (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index)
146 @findex newsticker-show-news
147 The command @code{newsticker-show-news} will display all available
148 headlines in a special buffer, called @samp{*newsticker*}. It will
149 also start the asynchronous download of headlines. The modeline in
150 the @samp{*newsticker*} buffer informs whenever new headlines have
151 arrived. Clicking mouse-button 2 or pressing RET in this buffer on a
152 headline will call @code{browse-url} to load the corresponding news
153 story in your favourite web browser.
155 @findex newsticker-start-ticker
156 @findex newsticker-stop-ticker
157 The scrolling, or flashing of headlines in the echo area, can be
158 started with the command @code{newsticker-start-ticker}. It can be
159 stopped with @code{newsticker-stop-ticker}.
161 @findex newsticker-start
162 @findex newsticker-stop
163 If you just want to start the periodic download of headlines use the
164 command @code{newsticker-start}. Calling @code{newsticker-stop} will
165 stop the periodic download, but will call
166 @code{newsticker-stop-ticker} as well.
169 @chapter Configuration
171 All Newsticker options are customizable, i.e. they can be changed with
172 Emacs customization methods: Call the command
173 @code{customize-group} and enter @samp{newsticker} for the customization
176 All Newsticker options have reasonable default values, so that in most
177 cases it is not necessary to customize settings before starting Newsticker
180 Newsticker options are organized in the following groups.
185 @code{newsticker-feed} contains options that define which news
186 feeds are retrieved and how this is done.
190 @vindex newsticker-url-list
191 @code{newsticker-url-list} defines the list of headlines which are
194 @vindex newsticker-retrieval-interval
195 @code{newsticker-retrieval-interval} defines how often headlines
200 @code{newsticker-headline-processing} contains options that define
201 how the retrieved headlines are processed.
205 @vindex newsticker-keep-obsolete-items
206 @code{newsticker-keep-obsolete-items} decides whether unread
207 headlines that have been removed from the feed are kept in the
212 @code{newsticker-layout} contains options that define how the
213 buffer for reading RSS headlines is formatted.
217 @vindex newsticker-heading-format
218 @code{newsticker-item-format} defines how the title of a headline
223 @code{newsticker-ticker} contains options that define how headlines
224 are shown in the echo area.
228 @vindex newsticker-display-interval
229 @vindex newsticker-scroll-smoothly
230 @code{newsticker-display-interval} and
231 @code{newsticker-scroll-smoothly} define how headlines are shown in
236 @code{newsticker-hooks} contains options for hooking other Emacs
237 commands to newsticker functions.
240 @vindex newsticker-new-item-functions
241 @code{newsticker-new-item-functions} allows for automatic
242 processing of headlines. See `newsticker-download-images', and
243 `newsticker-download-enclosures' for sample functions.
247 @code{newsticker-miscellaneous} contains other Newsticker options.
251 Please have a look at the customization buffers for the complete list
257 This newsticker is designed do its job silently in the background
258 without disturbing you. However, it is probably impossible to prevent
259 such a tool from slightly attenuating your Editor's responsiveness
260 every once in a while.
262 Byte-compiling newsticker.el is recommended.
