Module:Namespace detect/doc

This module allows you to output different text depending on the namespace that a given page is in. It is a Lua implementation of the {{namespace detect}} template, with a few improvements: all namespaces and all namespace aliases are supported, and namespace names are detected automatically for the local wiki.

Usage

{{#invoke: Namespace detect | main
| main              = <!-- text to return for the main namespace -->
| talk              = <!-- text to return for talk namespaces -->

<!-- text to return for specific subject namespaces -->
| portal            = 
| category          = 
| user 	            = 
| wikisource        = 
| ws                = 
| index             = 
| page	            = 
| mediawiki         = 
| author            = 
| translation       = 
| template          = 
| special           = 
| media             = 
| file              = 
| image             = 
| help 	            = 
| module            = 

| other             = <!-- text to return for unspecified namespaces -->
| demopage          = <!-- page to detect namespace for, if not the current page -->
| demospace         = <!-- namespace to display text for -->

| subjectns         = <!-- set to "yes" to treat talk pages as the corresponding subject page -->
}}

Parameters

• main - text to return if the page is in the main namespace.
• talk - text to return if the page is in a talk namespace. This can be any talk namespace - it will match any of "Talk:", "Wikipedia talk:", "User talk:", etc.
• Subject namespace parameters, e.g. wikipedia, user, file... - the text to return if the page is in the corresponding namespace. This module accepts all subject namespaces as parameters, including namespace aliases and virtual namespaces. See below for a list of supported values.
• other - text to return if no parameters for the page's namespace were specified. This text is also returned if |demospace= is set to an invalid namespace value.
• subjectns - if on a talk page, use the corresponding subject page. Can be set with values of "yes", "y", "true" or "1".
• demopage - specifies a page to detect the namespace of. If not specified, and if the |demospace= parameter is not set, then the module uses the current page.
• demospace - force the module to behave as if the page was in the specified namespace. Often used for demonstrations.

Namespace parameters

Possible values for subject namespace parameters are as follows:

Namespace	Aliases
main
user
wikisource	project, ws
file	image
mediawiki
template
help	h
category
portal
author
page
index
translation
timedtext
module

Table function

Use the following to display a table with the different possible namespace parameters:

{{#invoke:Namespace detect|table|talk=yes}}

To include the parameter for talk namespaces, use |talk=yes.

Porting to different wikis

This module is designed to be portable. To use it on a different wiki, all you need to do is to change the values in Module:Namespace detect/config. Instructions are available on that page.

Technical details

The module uses a data page at Module:Namespace detect/data. This page is loaded with mw.loadData, which means it is processed once per page rather than once per #invoke. This was done for performance reasons.
