Template:Excerpt/doc

勤求古训,博采众方

This template is used for reusing parts of pages in other pages. This practice has several advantages:

  • Reduces maintenance by avoiding duplicate content that must be updated multiple times
  • Improves content quality by encouraging editors to merge related content, rather than having multiple versions in various stages of development
  • Fosters collaboration by channeling contributors into one place, rather than working in parallel

This template extends the capabilities of the built-in [[<tvar name=1>Special:MyLanguage/Transclusion</tvar>|normal transclusion]].

Usage

Basic usage

  • {{Excerpt|Page title}} — Transclude the lead section ([[<tvar name=1>#Lead section</tvar>|example]])
  • {{Excerpt|Page title|Section title}} — Transclude a specific section, excluding any subsections ([[<tvar name=1>#Specific section</tvar>|example]])


Parameters

  • 1 — Title of the page to transclude. Only required parameter. By default the lead section will be transcluded ([[<tvar name=1>#Lead section</tvar>|example]]).

Notice that this template provides other ways of targeting specific elements of a page without having to resort to section tags.

  • more=yes — Show a "Read more..." link at the end
  • bold=yes — Keep bold text.

  • inline=yes — Wrap the excerpt with <tvar name=1><span></tvar> tags to use it inside other text.
  • references=no — Remove all references.
  • subsections=yes — Include subsections of the transcluded section. Notice that if the transclusion is done from a section level 3, and the transcluded subsections are level 3 too, then the transcluded subsections will show with the same hierarchy as the transcluding section, which is probably not desirable, so use with caution.


Replacing sections for excerpts

File:How to excerpt.webm
How to replace a section for an excerpt.

Sections are often summaries of more precise subpages.

Sometimes it's convenient to replace the content of such sections for excerpts of the subpages, after merging the original content of the section (if any) into the subpage.

This improves both the subpage and the section, reduces maintenance, drives contributors to collaborate, etc.

An efficient way to proceed is:


  1. Open the section in one tab and the subpage in another.


  1. Edit both.


  1. Copy the text of the section and paste it below the lead section of the subpage.


  1. Delete repeated content and adjust using common sense.


  1. Save the changes in the subpage with an edit summary like: Bring content from <tvar name=1>[[Page]]</tvar>.


  1. Back to the section, delete all content and replace it for an excerpt of the subpage.


  1. Save the changes in the section with an edit summary like: Move content to <tvar name=1>[[Subpage]]</tvar> and leave an excerpt.
