Headlines Plugin

Description

This plugin displays RSS and ATOM feeds from news sites. Use it to build news portals that show headline news.

Note: Syndic8.com ( http://www.syndic8.com/ ) is a good site listing many RSS feeds.

Syntax Rules

%HEADLINES{"..."}%

Parameter Explanation Default
"..." source of RSS feed; this can be an url (starting with http) or a web.topic location for internal feeds None; is required
href="..." (Alternative to above) N/A
refresh="60" Refresh rate in minutes for caching feed; "0" for no caching Global REFRESH setting
limit="12" Maximum number of items shown Global LIMIT setting
header Header. Can include these variables: - $channeltitle, $title: title of channel (channel.title)
- $channellink, $link: link of channel (channel.link)
- $channeldescription, $description: description (channel.description)
- $channeldate, $date: publication date of the channel (channel.pubDate)
- $rights: copyrights of the channel (channel.copyright)
- $imagetitle: title text for site (image.title)
- $imagelink: link for site (image.link)
- $imageurl: URL of image (image.url)
- $imagedescription: description of image (image.description)
Global HEADER setting
format Format of one item. Can include these variables:
- $title: news item title (item.title)
- $link: news item link (item.link)
- $description: news item description (item.description)
- $date: the publication date (item.pubDate, item.date)
- $category: the article category (item.category)
Global FORMAT setting

The header and format parameters might also use variables rendering the dc, image and content namespace information. Note, that only bits of interest have been implemented so far and those namespaces might not be implemented fully yet.

Rendering the dc namespace

The following variables are extracting the dc namespace info, that could be used in header and format. Nnote, that some of the variables are already used above. This is done by purpose to use different feeds with the same formating parameters. If there's a conflict the non-dc tags have higher precedence, i.e. a <title> content </title> is prefered over <dc:title> content </dc:title> .

  • $title: channel/article title (dc:title)
  • $creator: channel creator (dc:creator)
  • $subject: subject text; this will also add an image according to the subject hash list, see above (dc:subject)
  • $description: ... (dc:description)
  • $publisher: the channel/article publisher (dc:publisher)
  • $contributor: ... (dc:contributor)
  • $date: ... (dc:date)
  • $type: ... (dc:type)
  • $format: ... (dc:format)
  • $identifier: ... (dc:identifier)
  • $source: ... (dc:source)
  • $language: ... (dc:language)
  • $relation: ... (dc:relation)
  • $coverage: ... (dc: coverage)
  • $rights: ... (dc: rights)

Rendering the image namespace

An image:item is converted into an <img> tag using the following mappings:

  • src: image url (rdf:about attribute of the image.item tag)
  • alt: image title (title)
  • width: image width (image:width)
  • height: image height image:height)

Rendering the content namespace

The variable $content is refering to the <content:encoding> content </content:encoding>.

Examples

Slashdot News

Write

%HEADLINES{"http://slashdot.org/slashdot.rdf" 
  header="*[[$link][$title]]:* $description" 
  format="$t* [[$link][$title]]"
}%
to get the latest Slashdot news as a bullet list format:

Business Opportunities Weblog

Write

%HEADLINES{"http://www.business-opportunities.biz/feed" limit="3"}%

to get the latest postings on the "Business Opportunities" weblog:

HeadlinesPlugin ERROR: 500 SSL negotiation failed:

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, for example, %HEADLINESPLUGIN_SHORTDESCRIPTION%. Note: Don't modify the settings here; copy and customize the settings in Main.TWikiPreferences. For example, to customize the USERAGENTNAME setting, create a HEADLINESPLUGIN_USERAGENTNAME setting in Main.TWikiPreferences.

  • One line description, shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Show headline news in TWiki pages based on RSS and ATOM news feeds from external sites

  • Refresh rate in minutes for cached feeds. Disable caching: 0, default: 60
    • Set REFRESH = 60

  • Maximum number of items shown. Default: 100

    • Set USELWPUSERAGENT = yes

  • Timeout fetching a feed using the LWP::UserAgent. Default: 20
    • Set USERAGENTTIMEOUT = 20

  • Name of user agent. Default: TWikiHeadlinesPlugin/2.21
      * Set USERAGENTNAME = TWikiHeadlinesPlugin/2.21

  • Default header: (variables are explained in the syntax rules)
      * Set HEADER = <div class="headlinesChannel"><div class="headlinesLogo"><img src="$imageurl" alt="$imagetitle" border="0" />%BR%</div><div class="headlinesTitle">$n---+!! <a href="$link">$title</a></div><div class="headlinesDate">$date</div><div class="headlinesDescription">$description</div><div class="headlinesRight">$rights</div></div>

  • Default format of one item: (variables are explained in the syntax rules)
      * Set FORMAT = <div class="headlinesArticle"><div class="headlinesTitle"><a href="$link">$title</a></div>$n<span class="headlinesDate">$date</span> <span class="headlinesCreator"> $creator</span> <span class="headlinesSubject"> $subject </span>$n<div class="headlinesText"> $description</div></div>

  • Values taken from configure: (only supported if CPAN:LWP is installed)
    • $TWiki::cfg{PROXY}{HOST} - proxy host, such as "proxy.example.com";
    • $TWiki::cfg{PROXY}{PORT} - proxy port, such as "8080";
    • $TWiki::cfg{PROXY}{SkipProxyForDomains} - domains excluded from proxy, such as "intra.example.com, bugs.example.com";

Style sheets

The default HEADER and FORMAT settings use the following styles. See the style.css file defining the default CSS properties (indentation illustrates enclosure).
