A newsticker is a thing 39;; that asynchronously retrieves headlines from a list of news sites, 40;; prepares these headlines for reading, and allows for loading the 41;; corresponding articles in a web browser. 42 43;; Headlines consist of a title and (possibly) a small description. They 44;; are contained in "RSS" (RDF Site Summary) or "Atom" files. Newsticker 45;; should work with the following RSS formats: 46;; * RSS 0.91 47;; (see http://backend.userland.com/rss091 or 48;; http://my.netscape.com/publish/formats/rss-spec-0.91.html) 49;; * RSS 0.92 50;; (see http://backend.userland.com/rss092) 51;; * RSS 1.0 52;; (see http://purl.org/rss/1.0/spec) 53;; * RSS 2.0 54;; (see http://blogs.law.harvard.edu/tech/rss) 55;; as well as the following Atom formats: 56;; * Atom 0.3 57;; * Atom 1.0 58;; (see http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt) 59;; That makes Newsticker.el an "Atom aggregator, "RSS reader", "RSS 60;; aggregator", and "Feed Reader". 61 62;; Newsticker provides several commands for reading headlines, navigating 63;; through them, marking them as read/unread, hiding old headlines 64;; etc. Headlines can be displayed as plain text or as rendered HTML. 65 66;; Headlines can be displayed in the echo area, either scrolling like 67;; messages in a stock-quote ticker, or just changing. 68 69;; Newsticker allows for automatic processing of headlines by providing 70;; hooks and (sample) functions for automatically downloading images and 71;; enclosed files (as delivered by podcasts, e.g.). 72 73;; Requirements 74;; ------------ 75;; Newsticker can be used with GNU Emacs version 21.1 or later as well as 76;; XEmacs. It requires an XML-parser (`xml.el') which is part of GNU 77;; Emacs. If you are using XEmacs you want to get the `net-utils' package 78;; which contains `xml.el' for XEmacs. 79 80;; Newsticker requires a program which can retrieve files via http and 81;; prints them to stdout. By default Newsticker will use wget for this 82;; task. 83 84;; Installation 85;; ------------ 86 87;; If you are using Newsticker as part of GNU Emacs there is no need to 88;; perform any installation steps in order to use Newsticker. Otherwise 89;; place Newsticker in a directory where Emacs can find it. Add the 90;; following line to your Emacs startup file (`~/.emacs'). 91;; (add-to-list 'load-path "/path/to/newsticker/") 92;; (autoload 'newsticker-start "newsticker" "Emacs Newsticker" t) 93;; (autoload 'newsticker-show-news "newsticker" "Emacs Newsticker" t) 94 95;; If you are using `imenu', which allows for navigating with the help of a 96;; menu, you should add the following to your Emacs startup file 97;; (`~/.emacs'). 98;; (add-hook 'newsticker-mode-hook 'imenu-add-menubar-index) 99 100;; That's it. 101 102;; Usage 103;; ----- 104;; The command newsticker-show-news will display all available headlines in 105;; a special buffer, called `*newsticker*'. It will also start the 106;; asynchronous download of headlines. The modeline in the `*newsticker*' 107;; buffer informs whenever new headlines have arrived. Clicking 108;; mouse-button 2 or pressing RET in this buffer on a headline will call 109;; browse-url to load the corresponding news story in your favourite web 110;; browser. 111 112;; The scrolling, or flashing of headlines in the echo area, can be started 113;; with the command newsticker-start-ticker. It can be stopped with 114;; newsticker-stop-ticker. 115 116;; If you just want to start the periodic download of headlines use the 117;; command newsticker-start. Calling newsticker-stop will stop the 118;; periodic download, but will call newsticker-stop-ticker as well. 119 120;; Configuration 121;; ------------- 122;; All Newsticker options are customizable, i.e. they can be changed with 123;; Emacs customization methods: Call the command customize-group and enter 124;; `newsticker' for the customization group. 125 126;; All Newsticker options have reasonable default values, so that in most 127;; cases it is not necessary to customize settings before starting 128;; Newsticker for the first time. 129 130;; Newsticker options are organized in the following groups. 131 132;; * newsticker-feed contains options that define which news 133;; feeds are retrieved and how this is done. 134;; o newsticker-url-list defines the list of headlines which are 135;; retrieved. 136;; o newsticker-retrieval-interval defines how often headlines are 137;; retrieved. 138;; * newsticker-headline-processing contains options that define how the 139;; retrieved headlines are processed. 140;; o newsticker-keep-obsolete-items decides whether unread headlines that 141;; have been removed from the feed are kept in the Newsticker cache. 142;; * newsticker-layout contains options that define how the buffer for 143;; reading news headlines is formatted. 144;; o newsticker-item-format defines how the title of a headline is 145;; formatted. 146;; * newsticker-ticker contains options that define how headlines are shown 147;; in the echo area. 148;; o newsticker-display-interval and newsticker-scroll-smoothly define 149;; how headlines are shown in the echo area. 150;; * newsticker-hooks contains options for hooking other Emacs commands to 151;; newsticker functions. 152;; o newsticker-new-item-functions allows for automatic processing of 153;; headlines. See `newsticker-download-images', and 154;; `newsticker-download-enclosures' for sample functions. 155;; * newsticker-miscellaneous contains other Newsticker options. 156 157;; Please have a look at the customization buffers for the complete list of 158;; options. 159 160;; Remarks 161;; ------- 162;; This newsticker is designed do its job silently in the background 163;; without disturbing you. However, it is probably impossible to prevent 164;; such a tool from slightly attenuating your Editor's responsiveness every 165;; once in a while. 166 167;; Byte-compiling newsticker.el is recommended. 168 169;; ====================================================================== 170;;; History: 171 172;; 1.10 (2007-01-29) 173;; * Bugfixes mostly: `newsticker--decode-iso8601-date', 174;; `newsticker--sentinel', and others. 175;; * Renamed `newsticker--retrieval-timer-list' to 176;; `newsticker-retrieval-timer-list'.
