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:

<templatestyles src="User:Domino/CategoryTree.css" /><templatestyles src="Template:Templates_Nav/styles.css" /><div class="template-documentation"><div class="templates-nav"> [[:Category:Templates|<span style="color:black;">'''Index of templates'''</span>]]
<categorytree mode="all" hideprefix="always" style="width:260px;" class="highlight-root-only">Content templates</categorytree>
{{#categorytree:Documentation templates|mode="all"|hideprefix="always"|style="width:260px;"|class="highlight-root-only"}}
{{#categorytree:Interface templates|mode="all"|hideprefix="always"|style="width:260px;"|class="highlight-root-only"}}
{{#categorytree:Miscellaneous templates|mode="all"|hideprefix="always"|style="width:260px;"|class="highlight-root-only"}}
{{#categorytree:Navigation templates|mode="all"|hideprefix="always"|style="width:260px;"|class="highlight-root-only"}}
{{#categorytree:Tool templates|mode="all"|hideprefix="always"|style="width:260px;"|class="highlight-root-only"}}</div><div class="template-documentation-content">
