Help:MediaWiki namespace

The MediaWiki namespace is one of the standard namespaces in the database structure of the MediaWiki software, on which WikiQueer runs. The pages in this namespace (whose titles begin MediaWiki:) contain the text to be displayed in certain places in the web interface. Only administrators can edit this namespace, but all editors can propose changes on the appropriate talk pages. See also WikiQueer:MediaWiki messages for discussions about the content of MediaWiki pages.

Overview
The MediaWiki namespace is a mechanism allowing administrators to customise or translate the MediaWiki web interface.

'Caution: Some messages must have HTML links, and others must'' have wikilinks. To find out which is which, you must know where the message is used in the interface.'''

Because the changes to these pages have a global effect, they are protected from editing, and only administrators have the ability to edit them. Non-admins who would like to request a minor change can do so by using the template on the talk page of the MediaWiki page. More substantive changes should be discussed at WikiQueer:MediaWiki messages; an edit request should then be made if there is consensus for the change.

MediaWiki pages can not and should not have documentation on the page itself for several reasons, among other things &lt;noinclude> tags usually do not function in this namespace and the amount of data in MediaWiki space needs to be kept low for performance reasons. Instead a description of the message can be put at the top of the talk page. The template interface explanation is available for this. Pages using this template can be found in Category:MediaWiki messages with interface explanation.

Some messages have old documentation available by setting the 'language' to qqq. For instance MediaWiki:Login has old, and somewhat incorrect, documentation at MediaWiki:Login/qqq. Don't update the /qqq messages, instead update the top of the talk page.

Overview of messages
The template MediaWiki messages (shown below) lists a selection of key messages. Not included are


 * Abusefilter warnings, as there many of these, and they can be found here.
 * Tags added automatically to edit summaries by edit filters, which are listed at Special:Tags.
 * Messages describing Preferences options (Mediawiki:Tog-) - Search for these
 * Messages providing tooltips (Mediawiki:Tooltip-) - Search for these
 * Messages relating to Cite.php are listed and discussed at Help talk:Cite errors.
 * MediaWiki:Uploadtext and related subpages (the subpages transclude pages from WikiQueer: space) - these are covered at WikiQueer talk:Upload.
 * CSS files, which are described at MediaWiki talk:Common.css.
 * Gadget-related messages - Gadgets

The template interface explanation, used on MediaWiki talk: pages (generally those with some discussion), adds pages it is on into Category:MediaWiki messages with interface explanation.

A complete list of messages is available at Special:Allmessages. MediaWiki messages serving the software default are called "unmodified" and appear as red links in the Allmessages list, and do not appear in a Prefix-based search as they don't technically exist as pages. Because Special:Allmessages displays all system messages (the page is over 1 MB) some users might prefer to view these messages alphabetically: [ @] A B C D E F G H  I   J K L M N O P Q R S T U V W X Y Z

For a list of all MediaWiki pages, see Special:Prefixindex/MediaWiki:, or search the MediaWiki namespace.

Technical details
The MediaWiki namespace is a mechanism allowing administrators to customise or translate the MediaWiki web interface. It is enabled by default in recent mediawiki versions, mw:Manual:$wgUseDatabaseMessages = true enables them. The contents of the MediaWiki namespace pages override any corresponding settings in the language files, i.e., the static version of messages. Using the MediaWiki namespace is a bit slower than other namespaces.

The namespace number of     messages is 8, with a corresponding      namespace 9 to discuss individual messages. Some projects offer templates like editprotected to propose modifications, others have a page like Meta:Requests for help from a sysop or bureaucrat for this purpose.


 * Links to MediaWiki messages work like links to ordinary pages, examples:
 *  MediaWiki:Edit  MediaWiki:Edit,
 *  w:de:MediaWiki:Edit  w:de:MediaWiki:Edit,
 *  [ demo]  [ demo].

Each message in the  array in Messages.php corresponds to a page in the MediaWiki namespace. For example, there is a line in the php file:

'confirmprotect' =&gt; 'Confirm protection',

To this corresponds the page MediaWiki:Confirmprotect, and. When this page is edited the new message is automatically used for say. Similarly w:fr:MediaWiki:Confirmprotect has the content Confirmer la protection, note that the page name itself is not translated.

Inclusion

 * Inclusion of MediaWiki messages can make sense, as noted below historically these messages also covered the function of templates.
 * , see.
 * , colon function int: is a shorthand for MediaWiki:.
 * , but only as far as the message exists.
 * doesn't exist.

However many messages are not suited for inclusion, because they contain $1 and similar parameters not evaluated by the template parser, or raw CSS and XHTML markup not permitted on normal pages.

Interlanguage links
Interlanguage links in MediaWiki messages typically won't work as expected. Adding &lt;noinclude&gt;</tt> isn't good enough, because something has to evaluate it, as it's the case for messages included like ordinary templates, but not for messages used internally as system messages.

Instead, one can use in-page interlanguage links on the talk pages, does this for some major projects.

Strings exclusive to language file
Some text strings cannot be customised using this feature, and so can only be changed by editing the language file. These include:


 * The namespace titles "User", "WikiQueer", "Image", etc.
 * The names of the special pages
 * Month and days-of-the-week names
 * A number of items in Special:Preferences
