@chapter Overview
|
|
|
|
Newsticker provides a newsticker for Emacs. A newsticker is a thing
|
|
that asynchronously retrieves headlines from a list of news sites,
|
|
prepares these headlines for reading, and allows for loading the
|
|
corresponding articles in a web browser.
|
|
|
|
|
|
Headlines consist of a title and (possibly) a small description. They
|
|
are contained in "RSS" (RDF Site Summary) or "Atom" files. Newsticker
|
|
should work with the following RSS formats:
|
|
|
|
@itemize
|
|
@item RSS 0.91 (see @uref{http://backend.userland.com/rss091} or
|
|
@uref{http://my.netscape.com/publish/formats/rss-spec-0.91.html}),
|
|
@item RSS 0.92 (see @uref{http://backend.userland.com/rss092}),
|
|
@item RSS 1.0 (see @uref{http://purl.org/rss/1.0/spec}
|
|
@item RSS 2.0 (see @uref{http://blogs.law.harvard.edu/tech/rss}),
|
|
@end itemize
|
|
@itemize
|
|
as well as the following Atom formats:
|
|
@item Atom 0.3
|
|
@item Atom 1.0 (see
|
|
@uref{http://www.ietf.org/internet-drafts/draft-ietf-atompub-format-11.txt}).
|
|
@end itemize
|
|
|
|
That makes Newsticker.el an "Atom aggregator, "RSS reader", or "RSS
|
|
aggregator".
|
|
|
|
Newsticker provides several commands for reading headlines, navigating
|
|
through them, marking them as read/unread, hiding old headlines etc.
|
|
Headlines can be displayed as plain text or as rendered HTML.
|
|
|
|
Headlines can be displayed in the echo area, either scrolling like
|
|
messages in a stock-quote ticker, or just changing.
|
|
|
|
Newsticker allows for automatic processing of headlines by providing
|
|
hooks and (sample) functions for automatically downloading images and
|
|
enclosed files (as delivered by podcasts, e.g.).

@node Requirements
|
|
@chapter Requirements
|
|
|
|
Newsticker can be used with
|
|
@uref{http://www.gnu.org/software/emacs/emacs.html, GNU Emacs} version
|
|
21.1 or later as well as @uref{http://www.xemacs.org, XEmacs}. It
|
|
requires an XML-parser (@file{xml.el}) which is part of GNU Emacs. If
|
|
you are using XEmacs you want to get the @file{net-utils} package
|
|
which contains @file{xml.el} for XEmacs.
|
|
|
|
Newsticker requires a program which can retrieve files via http and
|
|
prints them to stdout. By default Newsticker will use
|
|
@uref{http://www.gnu.org/software/wget/wget.html, wget} for this task.
|
|
|
|
|
|
@node Installation
|
|
@chapter Installation
|
|
|
|
As Newsticker is part of GNU Emacs there is no need to perform any
|
|
installation steps in order to use Newsticker.
|
|
|
|
However, if you are using imenu, which allows for navigating with the
|
|
help of a menu, you should add the following to your Emacs startup file
|
|
(@file{~/.emacs}).
|
|
|
|
@lisp
|
|
(add-hook 'newsticker-mode-hook 'imenu-add-menubar-index)
|
|
@end lisp
|
|
|
|
That's it.
|
|
|
|
@node Usage
|
|
@chapter Usage
|
|
|
|
@findex newsticker-show-news
|
|
The command @code{newsticker-show-news} will display all available
|
|
headlines in a special buffer, called @samp{*newsticker*}. It will
|
|
also start the asynchronous download of headlines. The modeline in
|
|
the @samp{*newsticker*} buffer informs whenever new headlines have
|
|
arrived. Clicking mouse-button 2 or pressing RET in this buffer on a
|
|
headline will call @code{browse-url} to load the corresponding news
|
|
story in your favourite web browser.
|
|
|
|
@findex newsticker-start-ticker
|
|
@findex newsticker-stop-ticker
|
|
The scrolling, or flashing of headlines in the echo area, can be
|
|
started with the command @code{newsticker-start-ticker}. It can be
|
|
stopped with @code{newsticker-stop-ticker}.
|
|
|
|
@findex newsticker-start
|
|
@findex newsticker-stop
|
|
If you just want to start the periodic download of headlines use the
|
|
command @code{newsticker-start}. Calling @code{newsticker-stop} will
|
|
stop the periodic download, but will call
|
|
@code{newsticker-stop-ticker} as well.
|
|
|
|
@node Configuration
|
|
@chapter Configuration
|
|
|
|
All Newsticker options are customizable, i.e. they can be changed with
|
|
Emacs customization methods: Call the command
|
|
@code{customize-group} and enter @samp{newsticker} for the customization
|
|
group.
|
|
|
|
All Newsticker options have reasonable default values, so that in most
|
|
cases it is not necessary to customize settings before starting Newsticker
|
|
for the first time.
|
|
|

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