The RSS extension renders ("displays") one or more RSS feeds on a wiki page in a standard or user-definable format. Since version 2.00, the extension is compatible with Extension:WikiArticleFeeds which generates RSS or ATOM feeds from MediaWiki pages (authoring tool).

Download

A extensão pode ser recuperada diretamente a partir do Git [?]:

  • Navegar pelo código
  • Algumas extensões possuem tags para versões estáveis.
  • Cada pacote está associado com uma versão antiga do MediaWiki. Existe também um pacote "master" que contém a versão alfa mais recente (pode exigir uma versão alfa do MediaWiki).

Extraia o snapshot e coloque-o no diretório extensions/RSS/ de sua instalação do MediaWiki.

Se você estiver familiarizado com o Git e tem acesso shell para seu servidor, você pode obter a extensão, como se segue:

cd extensions/ git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/RSS.git

Instalação

  • Baixe e coloque o(s) arquivo(s) num diretório chamado RSS na sua pasta extensions/.
  • Adicione o seguinte código ao final do seu arquivo LocalSettings.php:
    wfLoadExtension( 'RSS' );
    
  • Yes Concluído – Navegue à página Special:Version em sua wiki para verificar se a instalação da extensão foi bem sucedida.

Uso

Use one section between ‎<rss>-tags for each feed. The rss element may contain parameters if you provide them as attributes to the rss element:

Parâmetros na tag RSS
atributos de tags opcionais comentário
template="name" 'name' (default: rss-item) is the name of a page in the MediaWiki template namespace (default: MediaWiki:Rss-item), which comprises the name of another template (default: MediaWiki:Rss-feed since version 1.90; Template:RSSPost before version 1.90) and a list of named variables of RSS Feed channel subelements (item), these values then being passed to this other template to finally format the RSS items.

Note that when a template is specified here, the extension doesn't pass to it the name of a - default - formatting template. The template specified here needs to take care of that by hard-coding the name of the other template. I.e the default template process is completely aborted.

templatename="Pagename" or

templatename="Namespace:Pagename"

'Pagename' is the name of a template page which is used in the default template MediaWiki:Rss-item (defining the channel subelements) to finally format the RSS items; the template can be in the template namespace (first example denotes a page Template:Pagename) or any other namespace (second example uses the full specified form Namespace:Pagename)
max="n" show at most n channel subelements (items)
highlight="term1 term2 ..." highlight terms in different colours
filter="term1 term2 ..." show only RSS items with at least one of the terms
filterout="term1 term2 ..." do not show any RSS item containing any of these terms
reverse display the RSS items in reverse order (since Version 2.25 seems to be a bug regarding the reverse sorting which may be worked around like this:

in \extensions\RSS\RSSParser.php edit line 62: $this->reversed = true; -> this needs to be set to false if entries should be sorted as dates desc (newest first) when the reverse variable is used in ‎<rss>)

date="(Y-m-d H:i:s)" date format string[1]
(since r111347)
item-max-length="1000" limits the number of character in item descriptions (since r111350)

This is not correctly working in v2.18 see tarefa T32377.

Tracking category

All pages in a wiki which use the RSS extension are automatically added to the RSS tracking Category:Pages_with_RSS_feeds.

Templates for channel subelements and styling the RSS Feed

A manual setup is not necessarily required. You can skip this complicated documentation section.
One template name has been changed: MediaWiki:Rss-feed since version 1.90; Template:RSSPost before version 1.90.[2]

The RSS extension renders feeds on wiki page by using two templates in the MediaWiki system namespace, which can be changed, or which wiki admins can redirected to user-editable namespaces. The mechanism is perhaps not easy to understand, but after its installation, the extension starts with a useful set of templates; a manual set-up is not required.

If a template is not specified, then the one in MediaWiki:Rss-item is used and determines only which RSS feed channel subelements (items) are used. The other template MediaWiki:Rss-feed determines how the complete feed is shown on wiki pages i.e. how and which channel items are shown are listed.

This is the template MediaWiki:Rss-item (since version 1.90) which determines which item elements are used[2]

{{ MediaWiki:Rss-feed \
| title = {{{title}}} \
| link = {{{link}}} \
| date = {{{date}}} \
| author = {{{author}}} \
| description = {{{description}}} }}

The selected items are passed to the other template MediaWiki:Rss-feed (since version 1.90)[2] which determines how the RSS Feed is rendered on the wiki pages. It iterates over each <item> of the RSS feed and substitutes the value of each element found there, e.g. <title>, <link>, <date>, <author>, etc.

Basic MediaWiki:Rss-feed template:

; '''<span class='plainlinks'>[{{{link}}} {{{title}}}]</span>'''
: {{{description}}}
: {{{author}}} {{{date}}}<!-- don't use newline here -->

An alternative improved MediaWiki:Rss-feed template requires the Extension:ParserFunctions:

<!-- The second is an improved version which requires Extension:ParserFunctions --> \
; '''<span class='plainlinks'>[{{{link}}} {{{title}}}]</span>''' \
{{#if: {{{description|}}} \
|: {{{description}}}}}{{#if: {{{author|}}} \
| {{#if: {{{date|}}} |: — {{{author}}} {{{date}}}}} \
| {{#if: {{{author|}}}|: — {{{author}}}}} {{#if: {{{date|}}}|:{{{date}}}}}|}}<!-- don't use newline here -->

Example

The following code renders the four recent items of the wikimedia blog feed on the present page and highlights some terms. The layout depends on the content of feed template MediaWiki:Rss-feed and also of the item template MediaWiki:Rss-item as mentioned above:

Configuration settings

Add any one of the following settings you want to customize to your LocalSettings.php.

Configuration settings in RSS.php
parameter default comment
$wgRSSCacheAge 3600 (one hour) Store entries in memcached for this many seconds
$wgRSSCacheCompare false Check cached content, if available, against remote. $wgRSSCacheCompare should be set to false or a timeout in seconds which is less than $wgRSSCacheAge after which a comparison will be made.
$wgRSSFetchTimeout 15 read timeout in seconds
$wgRSSUserAgent 'MediaWikiRSS/<Version> (+https://www.mediawiki.org/wiki/Extension:RSS) / MediaWiki RSS extension' User-Agent to use for fetching feeds
$wgRSSNamespaces null Ignore the RSS tag in all but the namespaces listed here

null means the ‎<rss> tag can be used anywhere

$wgRSSUrlWhitelist array() (deny any URL = no whitelisted URLs) URL whitelist of RSS Feeds, the whitelist is empty by default and no URLs are allowed. If there are items in the array, and the used feed URL isn't in the array, it will not be allowed.
Use array( "*" ) if you as admin want to allow anyone to use any feed Url. In case your whitelist entries are ignored, please use square bracktes for the array instead, e.g. $wgRSSUrlWhitelist = [ 'URL1', 'URL2', 'URL3', ];
$wgRSSUrlNumberOfAllowedRedirects 0 (no redirects are allowed) Maximum number of redirects to follow (defaults to 0). This should only be used when the target URLs are trusted to avoid attacks on intranet services accessible by HTTP.
$wgRSSProxy false Optional proxy server url and port number to be used for fetching feeds.

false: no proxy used

If you need a proxy for certain urls and not for others:
Example for disabling proxy use for certain urls in RSSParser::fetchRemote how to use a regular expression for a conditional proxy switching.

$wgRSSDateDefaultFormat "Y-m-d H:i:s" default date format[1] for RSS publication dates
$wgRSSItemMaxLength

(deactivated in version 2.12 r113297; will be activated later.)[3]

200 default maximum length of item descriptions (since r111350)
$wgRSSAllowLinkTag false to allow active links in feed items
$wgRSSAllowImageTag false If you allow to see images in feed items. Do not confuse this parameter with $wgAllowImageTag of MediaWiki core, Display of images causes privacy problems, because the image is fetched in the browser context, so the (image-) server log will contain data of the requesting browser, see the discussion here. Note that since 2013 due to the MediaWiki sanitizer, image tags which have the form <img src="blah"/> are not parsed correctly by the MediaWiki core sanitizer and are not displayed irrespective of this setting (see tarefa T48443).

If you want the image to show, set this to true in LocalSettings.php and in \extensions\RSS\RSSParser.php remove this part at lines 485

if ( isset( $wgRSSAllowImageTag ) && $wgRSSAllowImageTag ) {
            $extraInclude[] = "img";
        } else {
            $extraExclude[] = "img";
        }
