74 | @chapter Overview | |
75 | ||
76 | Newsticker provides a newsticker for Emacs. A newsticker is a thing | |
77 | that asynchronously retrieves headlines from a list of news sites, | |
78 | prepares these headlines for reading, and allows for loading the | |
79 | corresponding articles in a web browser. | |
80 | ||
81 | ||
82 | Headlines consist of a title and (possibly) a small description. They | |
83 | are contained in "RSS" (RDF Site Summary) or "Atom" files. Newsticker | |
84 | should work with the following RSS formats: | |
85 | ||
86 | @itemize | |
87 | @item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or | |
88 | @uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}), | |
89 | @item RSS 0.92 (see @uref{http://backend.userland.com/rss092}), | |
90 | @item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec} | |
91 | @item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}), | |
92 | @end itemize | |
93 | @itemize | |
94 | as well as the following Atom formats: | |
95 | @item Atom 0.3 | |
96 | @item Atom 1.0 (see | |
97 | @uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}). | |
98 | @end itemize | |
99 | ||
100 | That makes Newsticker.el an "Atom aggregator, "RSS reader", or "RSS | |
101 | aggregator". | |
102 | ||
103 | Newsticker provides several commands for reading headlines, navigating | |
104 | through them, marking them as read/unread, hiding old headlines etc. | |
105 | Headlines can be displayed as plain text or as rendered HTML. | |
106 | ||
107 | Headlines can be displayed in the echo area, either scrolling like | |
108 | messages in a stock-quote ticker, or just changing. | |
109 | ||
110 | Newsticker allows for automatic processing of headlines by providing | |
111 | hooks and (sample) functions for automatically downloading images and | |
112 | enclosed files (as delivered by podcasts, e.g.). | |
113 | ||
114 | @ifhtml | |
115 | Here are screen shots of the @uref{newsticker-1.7.png, version 1.7 | |
116 | (current version)} and some older screen shots: | |
117 | @uref{newsticker-1.6.png, version 1.6}, | |
118 | @uref{newsticker-1.5.png, version 1.5}, | |
119 | @uref{newsticker-1.4.png, version 1.4} | |
120 | @uref{newsticker-1.3.png, version 1.3}, | |
121 | @uref{newsticker-1.0.png, version 1.0}. | |

123 | ||
124 | @node Requirements | |
125 | @chapter Requirements | |
126 | ||
127 | Newsticker can be used with | |
128 | @uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version | |
129 | 21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It | |
130 | requires an XML-parser (@file{xml.el}) which is part of GNU Emacs. If | |
131 | you are using XEmacs you want to get the @file{net-utils} package | |
132 | which contains @file{xml.el} for XEmacs. | |
133 | ||
134 | Newsticker requires a program which can retrieve files via http and | |
135 | prints them to stdout. By default Newsticker will use | |
136 | @uref{http://www.gnu.org/software/wget/wget.html, wget} for this task. | |
137 | ||
138 | ||
139 | @node Installation | |
140 | @chapter Installation | |
141 | ||
142 | As Newsticker is part of GNU Emacs there is no need to perform any | |
143 | installation steps in order to use Newsticker. | |
144 | ||
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 | |
147 | (@file{~/.emacs}). | |
148 | ||
149 | @lisp | |
150 | (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index) | |
151 | @end lisp | |
152 | ||
153 | That's it. | |
154 | ||
155 | @node Usage | |
156 | @chapter Usage | |
157 | ||
158 | @findex newsticker-show-news | |
159 | The command @code{newsticker-show-news} will display all available | |
160 | headlines in a special buffer, called @samp{*newsticker*}. It will | |
161 | also start the asynchronous download of headlines. The modeline in | |
162 | the @samp{*newsticker*} buffer informs whenever new headlines have | |
163 | arrived. Clicking mouse-button 2 or pressing RET in this buffer on a | |
164 | headline will call @code{browse-url} to load the corresponding news | |
165 | story in your favourite web browser. | |
166 | ||
167 | @findex newsticker-start-ticker | |
168 | @findex newsticker-stop-ticker | |
169 | The scrolling, or flashing of headlines in the echo area, can be | |
170 | started with the command @code{newsticker-start-ticker}. It can be | |
171 | stopped with @code{newsticker-stop-ticker}. | |
172 | ||
173 | @findex newsticker-start | |
174 | @findex newsticker-stop | |
175 | If you just want to start the periodic download of headlines use the | |
176 | command @code{newsticker-start}. Calling @code{newsticker-stop} will | |
177 | stop the periodic download, but will call | |
178 | @code{newsticker-stop-ticker} as well. | |
179 | ||
180 | @node Configuration | |
181 | @chapter Configuration | |
182 | ||
183 | All Newsticker options are customizable, i.e. they can be changed with | |
184 | Emacs customization methods: Call the command | |
185 | @code{customize-group} and enter @samp{newsticker} for the customization | |
186 | group. | |
187 | ||
188 | All Newsticker options have reasonable default values, so that in most | |
189 | cases it is not necessary to customize settings before starting Newsticker | |
190 | for the first time. | |
191 | ||
192 | Newsticker options are organized in the following groups. | |

266 | @node Remarks | |
267 | @chapter Remarks | |
268 | ||
269 | This newsticker is designed do its job silently in the background | |
270 | without disturbing you. However, it is probably impossible to prevent | |
271 | such a tool from slightly attenuating your Editor's responsiveness | |
272 | every once in a while. | |
273 | ||
274 | Byte-compiling newsticker.el is recommended. | |
