This is the {{Namespace}} meta-template. It helps other templates detect what type of page they are on.

It detects and groups all the different 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 ([[Image:...]]) is now deprecated.

Note: For most cases it may be better to use the simpler namespace detection templates (see the see also section below). This template is more prone to human errors such as misspelling parameter names.

Usage

This template takes one or more parameters named after the different page types as listed above. Like this:

{{Namespace
 | main  = Article text
 | talk  = Talk page text
 | other = Other pages text
}}

If the template is on a main (article) page, it will return this:

{{SAFESUBST:#invoke:Namespace detect|main}}

If the template is on any other page than an article or a talk page, it will return this:

{{SAFESUBST:#invoke:Namespace detect|main}}

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:

{{Namespace
 | file     = File page text
 | category = Category page text
 | other    =
}}

On any pages other than file and category pages the code above will render nothing.

{{SAFESUBST:#invoke:Namespace detect|main}}

By using an empty parameter, you can make it so the template doesn't render anything for some specific page type. Like this:

{{Namespace
 | main  = 
 | other = Other pages text
}}

The code above will render nothing when on mainspace (article) pages, but will return this when on other pages:

{{SAFESUBST:#invoke:Namespace detect|main}}

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:

{{Namespace
 | main  = Article text
 | other = Other pages text
 | demospace = main
}}

No matter on what kind of page the code above is used, it will return this:

{{SAFESUBST:#invoke:Namespace detect|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:

{{Namespace
 | user  = User page text
 | other = Other pages text
 | page  = User:Example
}}

No matter on what kind of page the code above is used, it will return this:

{{SAFESUBST:#invoke:Namespace detect|main}}

It can be convenient to let your template understand the demospace and/or page parameter and send it on to the {{Namespace}} template. Like this:

{{Namespace
 | main  = Article text
 | other = Other pages text
 | demospace = {{{demospace|}}}
 | page  = {{{page|}}}
}}

If both the demospace and page parameters are empty or undefined, the template will detect page types as usual.
