NewsPlugin
Generate a short headlines topic from a list of news
Introduction
The News plugin implements a simple "Headlines" view, or summary, of a list of news or a weblog. Add a
%NEWS%
variable in a news topic named
Xxx to generate a headline topic named
XxxHeadlines.
Syntax Rules
One enters news as items of a bulleted list in a single source topic, most recent first. If somewhere in the topic, the keyword
%NEWS%
appears, then a new topic is created with the first line of the most recent news. Ending punctuation is removed from the headlines for a sleeker look.
Recommended usage is to
%INCLUDE%
the generated topic in some panel in a front page, and put a "More..." link in it to the source topic. The
%NEWS%
variable can be set in an HTML comment to hide it in the source topic:
<!-- %NEWS% -->
To change the default, use the syntax
%NEWS{parameter="value" ...}%
syntax with the following available parameters:
Parameter |
Value |
count |
The number of headlines to keep. Defaults to 5. |
pattern |
Gives a (partial) regular expression pattern to use to extract the news items. This pattern must occur at the beginning of a line in order to select a news item. The headline then becomes everything following the pattern until the end of the line. Defaults to (\t| )\*\s (i.e., a first-level bullet). |
postsep |
Appends this text to each headline. Defaults to newline |
prefix |
This text will be prepended to the generated topic. Defaults to nothing. |
presep |
Prepend each headline with this text. Defaults to <tab>*<space> |
suffix |
This text will be appended to the generated topic. Defaults to nothing. |
topic |
Name of generated headlines topic. Defaults to the name of the source topic with Headlines appended to it. |
trim |
If set to "no", trailings punctuation marks ( .,:; ) are not removed from headlines. Defaults to "yes" |
Examples
Example: Set the prefix, presep, and suffix to produce an HTML unordered (bullet) list:
%NEWS{presep="<li>" prefix="<ul>" suffix="</ul>"}%
Example: If the topic
MyCompanyNews contains:
