Template:Namespace detect

Template documentation follows
Note: the template above may sometimes be partially or fully invisible.
Visit "Template:Namespace detect/doc" to edit its documentation if it is available. (How does this work?)

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

It detects and groups all the different namespaces used on Wikipedia into several types:

main

Main (i.e. article) space, where normal Wikipedia articles are kept.

talk

Any talk space, including page names that start with "Talk:", "User talk:", "File talk:", etc.

• portal
• category
• user
• draft
• wikipedia
• mediawiki
• book
• timedtext
• template
• special
• media
• file
• help
• module

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

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

Article text

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

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:

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

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

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

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

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

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:

{{Namespace detect
 | 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:

Article text

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 detect
 | 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:

User page text

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

{{Namespace detect
 | 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.

Parameters

List of all parameters:

{{Namespace detect
| main  = 
...
| other =
| demospace = {{{demospace|}}} / main / talk / user /
              wikipedia / file / mediawiki / template /
              help / category / portal / other
| page  = {{{page|}}} / User:Example
}}

Note: Empty values to the "main" ... "other" parameters have special meaning.

Technical details

Namespace "Image" was renamed to "File" on 11 December 2008. This template was updated to understand both names well before that, thus it still works fine. For backwards compatibility it still understands "image" both as a parameter name, such as "image = File page text", and as a value "demospace = image".

If you intend to feed tables as content to the numbered parameters of this template, you need to know this:

Templates have a problem handling parameter data that contains pipes "|" unless the pipe is inside another template {{name|param1}} or inside a piped link [[Help:Template|help]]. Thus templates can not handle wikitables as input unless you escape them by using the {{!}} template. 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.

For more technical details, e.g. about copying this template to other projects and CSS-based namespace detection, see {{Main talk other}} and its talk page.

Usage

This template can be used to make a standard navigation box. It is intended for use within another template that standardises the title and contents of the box (see Template:ShipNavbox). This template SHOULD NOT be used directly within articles, as it creates a maintenance burden to do so whenever the contents of the box have to be updated.

The purpose of this template is to standardise the attributes of all navigation boxes, for example, their colours and other CSS attributes. The template is fairly simple, and could be extended to add other features in the future. Using this template allows changes to be implemented much quicker and easier than editing each template separately.

Syntax

{{navbox
|state      = uncollapsed, collapsed, plain, autocollapse (default)
|name       = mandatory - name of the template
|style      = optional - style for the whole table
|title      = mandatory - navbox header
|gtitleN    = optional - title of N-th group of items
|styleN     = optional - style for groupN; i.e. text-align
|groupN     = mandatory - list of groups of items
|fstyle     = optional - style for footer ; i.e. text-align
|footer     = optional - navbox footer
}}

• Groups: Currently there is no technical limit to the maximum number of groups.
  • Groups of items can be added as parameters: group1, group2, group3, ... up to groupN.
• Group title: Each group has its own title parameter: gtitle1, gtitle2, gtitle3, ... up to gtitleN. Note that the default width for the first column is 15%.
• Group style: Style may also be customised to each group in: style1, style2, style3, ... up to styleN.
  • Note that neither the title nor the items have any wiki-links built into the template. As a result, users of the template are free to use wiki-links as they wish.
• Line breaks: Line-breaks (<br />) are unnecessary, as text wrapping is done automatically by the template. This also includes links and text in gtitleN and groupN.
• Bullets: Create unordered lists with lines beginning with *.
• Pipe links: Because of the nature of template syntax, it may be necessary to use Template:! ({{!}}).

States

• Autocollapse: By default, the state of a navbox is "autocollapsed". This means that if the number of navboxes in a page exceeds the maximum allocation of the collapsible navboxes, then the remaining navboxes are collapsed automatically. For more information (or to change the setting), see MediaWiki:Common.js.
  • Currently, the autocollapse allocation is 2 (see MediaWiki:Common.js). This means that if there are 3 navboxes in a page, the third and subsequent navboxes will be collapsed automatically.
• Uncollapsed: Forces the navbox to be displayed.
  • All of the navboxes in this documentation are in the uncollapsed state.
• Collapsed: The reverse of uncollapsed. Forces the navbox to be hidden instead.
  • Navboxes with a height of more than 300 pixels will also be collapsed automatically. For more information (or to change the setting), see MediaWiki:Common.js.
• Plain: Removes the "show/hide" link.

Sub-groups

• For larger navboxes, it may be necessary to include sub-groups within a particular group of items. It is also possible to collapsible navboxes within the parent navbox, see Collapsible sub-groups.
• To create sub-groups within {{navbox}}, certain parameters are to be included:
  • The parent navbox group (i.e. group2 in the example below) requires the type parameter (gtype2 = Subgroup).
  • The nested navbox (sub-group) requires the inclusion of the sub-group parameter (subgroup = yes). This enables the template to differentiate between the sub-group and the parent navbox.

{{navbox
|name    =
|title   =
|gtitle1 =
|group1  =
|gtitle2 =  
|gtype2  = Subgroup (mandatory)
|group2  = 
  {{navbox
  |subgroup = yes (mandatory)
  |gtitle1  = 
  |group1   =
  |gtitle2  = 
  |group2   = 
  }}
}}

Collapsible sub-groups

• For extremely long navboxes, it is recommended to use collapsible navboxes within the parent navbox. Further sub-groups can then be added to these collapsible navboxes.
• To create collapsible sub-groups within {{navbox}}, these parameters need to be included:
  • The parent navbox is almost always uncollapsed (state=uncollapsed).
  • The parent navbox group (i.e. group1 in the example below) requires the type parameter (gtype1 = Subgroup).
  • The nested collapsible navbox requires the inclusion of the collapsible parameter (collapsible = yes). This enables the template to differentiate between the collapsible navbox and the parent navbox.
  • The nested collapsible navbox is forcefully collapsed (state=collapsed).

{{navbox
|state  = uncollapsed
|name   = 
|gtype1 = Subgroup
|group1 = 
  {{navbox
  |collapsible = yes
  |state   = collapsed
  |title   = 
  |gtitle1 = 
  |group1  = 
  |gtitle2 = 
  |group2  = 
  }}
}}

Use of images

• The use of images in navboxes is permitted, but please resize the images to keep them small. Inventory-sized images (25-30 pixels) are recommended.
• Please use {{t|plink}} to create links with images. Use {{t|plink}} for any case where text is not desired after the link. It functions the same as {{t|plink}}, but it does not produce a wikilink in text. Use {{t|chatl}} to link chatheads. These templates create links for both the image and text (except for {{t|plink}}) using far less wikicode than the standard syntax.

Link and file share the same name

{{plink|Item}}

File name differs from the link

{{plink|Item|File}}

Link and file share the same name, but different text is desired to display

{{plink|Item|alt=Text}}

File name differs from the link and different text is desired to display

{{plink|Item|File|alt=Text}}

Categorising

Navboxes are very useful for transcluding categories onto a large number of pages that share both a trait and the navigation box. For example: Template:ShipNavbox transcludes Category:Ships onto every page that uses it.

There are 2 methods of categorising pages with navboxes:

The first way is with {{t|Ctg}}. This is the preferred method, and can be used in most cases. The rules and operations for the Category handler template are very simple; however, they are enough to produce the desired results on most pages.

Categorisation should only be used on a template for large-scale addition. It is unhelpful, for example, to use a rule that only applies to 1 page.

    {{navbox
    |subgroup = Yes
    |gtitle1  = Level 3 Title 1
    |group1   =
    |gtitle2  = Level 3 Title 2
    |group2   =
    }}
  |gtitle4  = Level 2 Title 4
  |group4   = 
  }}
|gtitle6 = Level 1 Title 6
|group6  = 
|gtitle7 = Level 1 Title 7
|group7  = 
|fstyle  = 
|footer  = 
}}

Preventing unwanted documentation

The Navbox template's documentation is automatically transcluded under the navbox on any Template namespace page. It is not transcluded when used as a sub-group or collapsible sub-group template (subgroup= yes or collapsible=yes).

Should the documentation appear when it is unwanted, it can be hidden by setting the doc parameter doc=no on the template. In most cases, the doc parameter is NOT used and the parameter is removed completely.
