<!-- Categories at the bottom of this page, please; interwikis at Wikidata -->
== Purpose ==
This template is for explicitly indicating that the content inside it represents example output from a computer program or other machine source ([[automated attendant]]/[[interactive voice response]] call system, [[exit code]] of an application, [[standard output]], LCD display, etc.) It uses the [[[XHTML|X]]][[HTML]] element {{tag|samp}} (''sample output'') which exists for this purpose, and applies some styling to it, namely a faint greying out of the text color to visually difference it from source code and input. It retains the default monospaced (non-proportional) font style of the {{tag|samp|open}} element. Because it uses {{tag|samp}} instead of simply applying visual style effects, it is [[semantic markup]] that conveys meaning, and it can be further acted upon by the user agent (e.g. with custom local style sheets). This tag is the exact opposite of {{tlx|kbd}}, which is for example input.
== Usage ==
The template takes one mandatory parameter, the content to be marked up. If this content contains "=" (an equals sign), the parameter {{em|must}} be explicitly named {{para|1}}, or the template will fail. (This is a limitation of the MediaWiki software, not the template.) It is always safer to use {{para|1}} syntax. It may be used as a container for {{tlx|var}}, {{tlx|varserif}} or {{tag|var}} when the example output contains or consists entirely of a variable. It may also be used with (but not inside) {{tlx|code}}, or with {{tag|code}} (it generally should not be used inside the latter, as output is not a part of source code, but something that results from it; however, this style can be used to illustrate computer display of mixed type, as illustrated below).
For cases where it is useful to display the color of the output, there is an optional parameter {{para|color}} that takes an [[Web colors|HTML color name or <code>#<var>nnnnnn</var></code> color code]] (in which case the <code>#</code> is mandatory). For [[WP:ACCESSIBILITY|accessibility]] reasons, color should never be the only distinguishing factor, as {{samp|foo|color=red}} and {{samp|foo|color=green}} may be indistinguisahble to color-blind readers.
There may also be cases where some other aspect of the output may need to be reproduced; the {{para|style}} parameter accepts any complete CSS statement(s), terminating with a semicolon, e.g. {{para|style|font-variant:small-caps; font-style:italic;}}.
Examples:
* {{tnull|samp|1{{=}}[A]bort, [R]etry, [F]ail?}}: "The error message {{samp|1=[A]bort, [R]etry, [F]ail?}} has been cited as notoriously user-unfriendly."
* {{tnull|samp|%}} with {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}}: "At the {{samp|%}} prompt, the user must enter {{kbd|1=ssh {{var|hostname}}}}."
* {{tnull|samp|Error|color{{=}}red}}, to indicate output color: On failure, the {{samp|Error|color=red}} light activates.
* {{tnull|samp|Error|color{{=}}red|style{{=}}font-variant:small-caps;}}, for more customization: On failure, the {{samp|Error|color=red|style=font-variant:small-caps;}} light activates.
<!--The section below only makes sense if you remember that when /doc pages are included into the template page they belong to, their background is light green!
-->Some of these examples may look slightly different outside this documentation, because the default background color varies by page type (articles are stark white, template documentation pale green, most other pages very pale grey). In-article example:
<div style="background:#FFFFFF;">
* {{tnull|samp|1{{=}}[A]bort, [R]etry, [F]ail?}}: "The error message {{samp|1=[A]bort, [R]etry, [F]ail?}} has been cited as notoriously user-unfriendly."
* {{tnull|samp|%}} with {{tnull|kbd|1{{=}}ssh <nowiki>{{var|hostname}}</nowiki>}}: "At the {{samp|%}} prompt, the user must enter {{kbd|1=ssh {{var|hostname}}}}."
* {{tnull|samp|Error|color{{=}}red}}, to indicate output color: On failure, the {{samp|Error|color=red}} light activates.
* {{tnull|samp|Error|color{{=}}red|style{{=}}font-variant:small-caps;}}, for more customization: On failure, the {{samp|Error|color=red|style=font-variant:small-caps;}} light activates.
