This is a documentation subpage for Template:Tlx (see that page for the template itself).
It contains usage information, categories and other content that is not part of the original template page.


{{Tlx|Template|first parameter|second|third|...|tenth}}{{Template|first parameter|second|third|...|tenth}}

Where parameters might contain "=" characters, use {{=}} instead

{{Tlx|Template|first parameter{{=}}anything|second|third{{=}}something|...|tenth}}{{Template|first parameter=anything|second|third=something|...|tenth}}

For more than 10 parameters, possibly also containing "=", use


The Ellipsis|three dots in the examples represent a number of arguments that have been omitted and are not an actual argument.

Purpose and naming

Wikt:mnemonic|Mnemonically 'Template link expanded'. After {{Tl}} 'Template link'.

  • This template takes another template-name and some associated pipe-tricked [[m:Parameter#Parameters|(numbered) parameters (or 'pass parameters'), and displays them as an 'example demonstration' of how the template-name template could be coded, literally. Its primary use is in instruction and documentation.
  • Specifics: Up to 10 pass parameters (numbered or nowiki-keywords) for the specified template are displayed as 'placeholders', and over 10 parameters can be displayed using a coded vertical-bar (as in "&#124;..."). A keyword parameter can be used with equals code &#61; or {{=}} or in nowiki-text: "<nowiki>size=10</nowiki>

" or all parameters as a string in "<nowiki>

" tags; see Examples at bottom.

  • Exceptions: If the intended template lists numerous parameters, then perhaps this template should really not be used, and just hardcode the usage with <code>


, for example: <code><nowiki>{{Anytemplate|arg1=23|size=250px|other parameters...}}</nowiki></code>

. If a vertical display, with parameters on their own lines, is desired, this can also be laid out manually in this manner, or more rapidly done with <pre>...</pre>



  • If given no additional parameters except  'template name' ({{{1}}}),  it presents the same as the similar {{Tl}}
Macro (computer science)|macro template -- a blue link nested in brackets|curly-braces-- the same as a user would apply the template without parameters, but with a noticeably clearer font and spacing on most modern browsers. 
    • {{Tl|Tl}} display compared to {{Tlx|Tl}}: (Tl: {{Tl}}
versus Tlx: {{Tl}}) 
  • Comparatively, {{Tl}} will not take or display additional parameters, and for minor technical reasons, may be preferred for mere listing and referencing in long pages involving a lot of template expansions.
  • {{Tlx}} has a named parameter |subst=. Setting this parameter to any non-blank value will place the string "subst:" before the template name, linked to Help:Substitution. This is useful to indicate when a template should be substituted. For example {{Tlx|Welcome|subst=Y}} will display {{subst:Welcome}}. This is similar to the action of the {{tlxs}} template: {{Tlxs|Welcome}} will display {{subst:welcome}}


  • Additionally, Tlx will take a named parameter |SISTER= to link interwiki to H:IW|other sister projects such as one of these examples: para|SISTER|M: (m:|Meta), |SISTER=Q: (q:|WikiQuote), |SISTER=S: (WikiSource), etc. allowing documentation or discourse about a template across interwiki boundaries.
  • Tlx will also take a named parameter |LANG= to link to H:ILL|other language Wikipedias, such as one of these examples: para|LANG|de: (:de:|German), |LANG=sv: (:sv:|Swedish), etc. allowing documentation or discourse about a template across language boundaries.


{{Tlx}} is a generalization of {{Tl}}

, {{Tlp}}

, etcetera with arguably better readable output. This depends on the browser, but too narrow uses of "{", "|", "}" in conjunction with links can be hard to read.

Up to 10 placeholders for parameters of the specified template


On the source sister projects, en.wikipedia and Meta, X0, X1, X2,..., X9 are sandbox templates for experimentation on involved templates that need be in template space. An auto-cleansing software facility exists that might be used to duplicate the facility on other Sister projects.

  • Template:Tlxb – same as {{Tlx}}

, but gives the template name in boldface type (this can be useful when stressing the difference between two similarly named templates). Template:Tlb is the same, except it uses regular text instead of a monospaced non-proportional font.

  • Template:Temt, – same as {{Tlx}}

, but handles template names with the Template: prefix and templates not in the Wikipedia:Namespace|Template: namespace {{ns:10}}.

  • Template:Para – for giving examples of template parameters and values only, instead of entire templates with parameters.
