Module:Namespace detect/doc
This is the documentation page for Module:Namespace detect
This Lua module is used in system messages, and on approximately 15,900,000 pages, or roughly 1111111% of all pages. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
File:Lua-Logo.svg | This module depends on the following other modules: |
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 | page = <!-- page to detect namespace for, if not the current page --> | 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 = | wikipedia = | mediawiki = | book = | timedtext = | template = | special = | media = | file = | image = | help = | module = | other = <!-- text to return for unspecified namespaces --> | 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

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.
