| This is the {{t|Namespace}} meta-template. It helps other templates detect what type of page they are on.
| | {{delete|Useless template that does not work on this wiki}} |
| | |
| It detects and groups all the different [[Wikipedia:Namespace#Enumeration|namespaces]] used on Fandom into several types:
| |
| | |
| ; main : Main (i.e. article) space, where normal articles are kept.
| |
| ; talk : Any talk space, including page names that start with "Talk:", "User talk:", "File talk:", etc.
| |
| ;user
| |
| ;file
| |
| ;mediawiki
| |
| ;template
| |
| ;help
| |
| ;category
| |
| : The remaining namespaces.
| |
| ; other : Any namespaces that were not specified as a parameter to the template (see explanation below).
| |
| | |
| For backwards compatibility, this template handles '''image''' as if '''file'''. '''image''' (<nowiki>[[Image:...]]</nowiki>) is now deprecated.
| |
| | |
| '''Note:''' For most cases it may be better to use the simpler namespace detection templates (see the [[#See also|see also]] section below). This template is more prone to human errors such as misspelling parameter names.
| |
| | |
| This template uses the [[w:Help:Lua|Lua templating language]], and more information can be found [[w:c:dev:Global_Lua_Modules/Namespace_detect|on the Global Lua Module page]]. '''For a traditional wikitext version of this template, see [[w:c:templates:Template:Namespace_detect|Namespace_detect on Templates Wiki]]'''.
| |
| | |
| == Usage ==
| |
| | |
| This template takes one or more parameters named after the different page types as listed above. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | main = Article text
| |
| | talk = Talk page text
| |
| | other = Other pages text
| |
| }}
| |
| </pre>
| |
| | |
| If the template is on a main (article) page, it will return this:
| |
| : {{Namespace |demospace=main
| |
| | main = Article text
| |
| | talk = Talk page text
| |
| | other = Other pages text
| |
| }}
| |
| | |
| If the template is on any other page than an article or a talk page, it will return this:
| |
| : {{Namespace
| |
| | main = Article text
| |
| | talk = Talk page text
| |
| | other = Other pages text
| |
| }}
| |
| | |
| The example above made the template return something for all page types. But if we don't use the '''other''' parameter or leave it empty, it will not return anything for the other page types. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | file = File page text
| |
| | category = Category page text
| |
| | other =
| |
| }}
| |
| </pre>
| |
| | |
| On any pages other than file and category pages the code above will render nothing.
| |
| <!-- Do not remove this one. It is supposed to render nothing, but we have it here for testing purposes. -->
| |
| : {{Namespace
| |
| | file = File page text
| |
| | category = Category page text
| |
| | other =
| |
| }}
| |
| | |
| By using an empty parameter, you can make it so the template doesn't render anything for some specific page type. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | main =
| |
| | other = Other pages text
| |
| }}
| |
| </pre>
| |
| | |
| The code above will render nothing when on mainspace (article) pages, but will return this when on other pages:
| |
| : {{Namespace
| |
| | main =
| |
| | other = Other pages text
| |
| }}
| |
| | |
| == Demospace and page ==
| |
| | |
| For testing and demonstration purposes, this template can take two parameters named '''demospace''' and '''page'''.
| |
| | |
| '''demospace''' understands any of the page type names used by this template, including the '''other''' type. It tells the template to behave like it is on some specific type of page. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | main = Article text
| |
| | other = Other pages text
| |
| | demospace = main
| |
| }}
| |
| </pre>
| |
| | |
| No matter on what kind of page the code above is used, it will return this:
| |
| : {{Namespace
| |
| | main = Article text
| |
| | other = Other pages text
| |
| | demospace = main
| |
| }}
| |
| | |
| The '''page''' parameter instead takes a normal pagename, making this template behave exactly as if on that page. The pagename doesn't have to be an existing page. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | user = User page text
| |
| | other = Other pages text
| |
| | page = User:Example
| |
| }}
| |
| </pre>
| |
| | |
| No matter on what kind of page the code above is used, it will return this:
| |
| : {{Namespace
| |
| | user = User page text
| |
| | other = Other pages text
| |
| | page = User:Example
| |
| }}
| |
| | |
| It can be convenient to let your template understand the '''demospace''' and/or '''page''' parameter and send it on to the {{T|Namespace}} template. Like this:
| |
| <pre>
| |
| {{Namespace
| |
| | main = Article text
| |
| | other = Other pages text
| |
| | demospace = {{{demospace|}}}
| |
| | page = {{{page|}}}
| |
| }}
| |
| </pre>
| |
| | |
| If both the '''demospace''' and '''page''' parameters are empty or undefined, the template will detect page types as usual.
| |
| | |
| == Parameters ==
| |
| | |
| List of all parameters:
| |
| <pre>
| |
| {{Namespace
| |
| | main =
| |
| ...
| |
| | other =
| |
| | demospace = {{{demospace|}}} / main / talk / user /
| |
| file / mediawiki / template /
| |
| help / category / other
| |
| | page = {{{page|}}} / User:Example
| |
| }}
| |
| </pre>
| |
| | |
| == Technical details ==
| |
| If you intend to feed tables as content to the numbered parameters of this template, you need to know this:
| |
| | |
| [[w:Help:Template|Templates]] have a problem handling parameter data that contains pipes "<code>|</code>" unless the pipe is inside another template <code><nowiki>{{name|param1}}</nowiki></code> or inside a piped link <code><nowiki>[[w:Help:Template|help]]</nowiki></code>. Thus templates can not handle [[w:Help:Table|wikitables]] as input unless you escape them by using the <code><nowiki>{{!}}</nowiki></code> [[w:Help:Magic words|magic word]]. This makes it hard to use wikitables as parameters to templates. Instead, the usual solution is to use HTML wikimarkup for the table code, which is more robust.
