{{#ifeq:{{BASEPAGENAME}}|Tlx |{{High-risk|2325910+}} {{Used in system}} }}

This template is used to show example template usage without expanding the template itself.

==Basic use==
''(Note: In the following examples, [[Ellipsis|ellipses (groups of three dots)]] indicate where parameters have been omitted.)''

: {{tlx{{\sandbox}}|tlx|Template|''first parameter''|''second parameter''|''third parameter''|...|''tenth parameter''}} produces: {{tlx{{\sandbox}}|Template|''first parameter''|''second parameter''|''third parameter''|...|''tenth parameter''}}

When you want to indicate setting a value to one or more parameters, you would normally use the equals-sign ("="). This doesn't work here; instead use {{tlf|{{=}}}}, like so:
: {{tlx{{\sandbox}}|tlx|Template|''first''<nowiki>{{=}}</nowiki>''first value''|''second''|''third''<nowiki>{{=}}</nowiki>''third value''}} produces: {{tlx{{\sandbox}}|Template|''first{{=}}first value''|''second''|''third{{=}}third value''}}

For more than ten parameters – with or without equals-signs – instead wrap the entire list of parameters and their values in {{tag|nowiki}} tags. When you do, you don't need to replace equals-signs. For instance:
: {{tlx{{\sandbox}}|tlx|Template|<nowiki><nowiki>''first''|''second''|''third=value''|...|''999th''</nowiki></nowiki>}} produces: {{tlx{{\sandbox}}|Template|<nowiki>first|second|third=value|...|999th</nowiki>}}

==Purpose and naming==
Mnemonically, ''template link expanded'' (after ''[[Template:tl|template link]]'').

This template allows an example of calling a template, accompanied by one or more parameters, to be displayed without also causing the template to be called.

Up to 20 of the template's parameters (numbered or nowiki-keywords) may be displayed as placeholders, while more than over 20 parameters can be displayed using a coded vertical bar (pipe) symbol, as in <code>&#124;</code>. A keyword parameter can be used with equals code &#61; or <nowiki>{{=}}</nowiki> or in nowiki-text: "{{tag|nowiki|content=size=10}}" or all parameters as a string in "{{tag|nowiki|o}}" tags; see ''[[#Examples|Examples]]'' at bottom. For more details, see [[{{TALKPAGENAME}}|this talk]] page. If you use 21 or more parameters, all after the 20th will be replaced with a single {{para||...}} at the end of the parameter list.

; Exceptions
If the intended template lists numerous parameters, then perhaps this template should really {{em|not}} be used, and just hardcode the usage with {{tag|code|o}}{{tag|nowiki|o}}. For example:
: {{tag|code|content={{tag|nowiki|content=<nowiki>{{Anytemplate|arg1=23|size=250px|</nowiki><var>other parameters...</var><nowiki>}}</nowiki>}}}}.
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 {{tag|pre}}.

===Parameters===
*If the only parameter supplied is {{param|1}}, i.e. a template's name, {{tlx|tlx}}'s output is the same as {{tlx|tl}} – i.e. a link within [[Braces (punctuation)|braces]] – but in a [[monospaced font]]:
**{{tc|tl|tl}} produces: {{tl|tl}}
**{{tc|tlx|tl}} produces: {{tlx{{\sandbox}}|tl}}
: {{tlx|tl}} will also not take nor display additional parameters.

; Named parameters
{{para|subst}}
: Setting this parameter to any non-blank value will prefix the string <code>subst:</code> linked to [[Help:Substitution]]. This is useful to indicate when a template should be substituted. For example, {{tlx{{\sandbox}}|tlx|Welcome|3=subst=Y}} produces: {{tlx{{\sandbox}}|Welcome|subst=Y}}. This is similar to the action of the {{tlx{{\sandbox}}|tlxs}} template: {{tlx{{\sandbox}}|tlxs|Welcome}} produces: {{tlxs|Welcome}}.
{{para|SISTER}}
: For an interwiki link to [[H:IW|other sister projects]], such as: {{para|SISTER|M:}} ([[m:|Meta]]), {{para|SISTER|Q:}} ([[q:|WikiQuote]]), {{para|SISTER|S:}} ([[s:|WikiSource]]), etc, facilitating interwiki template documentation and/or discussion.
{{para|LANG}}
: For a link to [[H:ILL|Wikipedias in other languages]], such as: {{para|LANG|de:}} ([[:de:|German]]), {{para|LANG|sv:}} ([[:sv:|Swedish]]), etc, facilitating cross-language template documentation and/or discussion.

==Documentation==
{{tl|Tlx}} is a generalization of {{tl|tl|x}}, {{tl|tlp|x|y}} etc., with output that is arguably more legible. This depends on the browser, but narrow gaps between characters such as "{{thin space}}'''{'''{{thin space}}", "{{thin space}}'''|'''{{thin space}}", "{{thin space}}'''}'''{{thin space}}" and links can be hard to read when not monospaced (and hard to click on; for uses like <code><nowiki>{{!}}</nowiki></code>, see {{tl|tlw}}, which makes the click target bigger).

===Usage===
:<code>{{tlx{{!}}Templatename}}</code>
:<code>{{tlx{{!}}Templatename{{!}}param}}</code>
:<code>{{tlx{{!}}Templatename{{!}}1{{!}}2{{!}}3{{!}}4{{!}}5{{!}}6{{!}}7{{!}}8{{!}}9{{!}}10}}</code>
:<code>{{tlx{{!}}Templatename{{!}}1{{!}}2{{!}}3{{!}}4{{!}}5{{!}}6{{!}}7{{!}}8{{!}}9{{!}}10&#124;more}}</code>
:<code>{{tlx{{!}}Templatename{{!}}param&#61;value}}</code>
There are up to 10 placeholders for parameters of the specified template.

===Examples===
{{#switch:{{SITENAME}} |Wikipedia|Meta= |
; Note: At the en.wikipedia and Meta sites, '''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.
