Module:TemplateSource

Meant to be used with the {{Template source}} template. Returns the plaintext contents of a template. Obeys the mostly the same behaviours as transclusion would, respects <onlyinclude>, <includeonly>, and <noinclude> tags. This module is primarily meant to be used as input to <syntaxhighlight>, which doesn't handle some tags (like or <categorytree>) correctly.

Example

The source of the {{Pagetabs}} template, wrapped in a <syntaxhighlight> tag.

{{#tag:syntaxhighlight|{{#invoke:TemplateSource|templateSource|Template:Pagetabs}}|lang=html|line=1}} generates:

{{#ifeq: {{NAMESPACE}} | {{ns:Template}} | {{#ifeq: {{#sub:{{ROOTPAGENAME}}|0|3}} | Tab | [[Category:Tabs]] |}} |}}<templatestyles src="Pagetabs/styles.css" /><div class="pagetabs noexcerpt noscrollbar" {{#if:{{{styles|}}}|style="{{{styles}}}|}} ><!--
--><div>[[{{{tab1|}}}|{{{title1|{{{tab1|}}}}}}]]</div><!--
--><div>[[{{{tab2|}}}|{{{title2|{{{tab2|}}}}}}]]</div><!--
-->{{#if:{{{tab3|}}}|<div>[[{{{tab3|}}}|{{{title3|{{{tab3|}}}}}}]]</div>}}<!--
-->{{#if:{{{tab4|}}}|<div>[[{{{tab4|}}}|{{{title4|{{{tab4|}}}}}}]]</div>}}<!--
-->{{#if:{{{tab5|}}}|<div>[[{{{tab5|}}}|{{{title5|{{{tab5|}}}}}}]]</div>}}<!--
-->{{#if:{{{tab6|}}}|<div>[[{{{tab6|}}}|{{{title6|{{{tab6|}}}}}}]]</div>}}<!--
--></div>
<hr />
<!-- moved to Template:Tab Userpage <div class="pagetabsmore">{{Pagetabs/pagetabsmore|username=|style=position:absolute; bottom:24px;}}</div> -->
