Template:Excerpt

{{Documentation|content=

{{Lua|Module:Excerpt}}

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 1>Special:MyLanguage/Transclusion|normal transclusion.

Basic usage

 * — Transclude the lead section (1>#Lead section|example)
 * — Transclude a specific section, excluding any subsections (1>#Specific section|example)

Parameters

 * — Title of the page to transclude. Only required parameter.  By default the lead section will be transcluded (1>#Lead section|example).
 * — Title of the section to transclude (2>#Specific section|example).
 * — Name of the fragment to transclude. Must be marked with   and   in the transcluded page (3>#Specific fragment|example). Notice that this template provides other ways of targeting specific fragments of a page without having to resort to section tags.
 * — Elements to transclude (1>#Files only|example). By default all elements are transcluded.
 * or  — Transclude only files
 * or  — Transclude only lists
 * or  — Transclude only tables
 * or  — Transclude only templates
 * or  — Transclude only paragraphs
 * — Paragraphs to transclude. By default all paragraphs are transcluded.
 * — Transclude no paragraphs
 * — Transclude the first paragraph
 * — Transclude the second paragraph
 * — Transclude the first and third paragraphs
 * — Transclude the first, second and third paragraphs
 * — Transclude the first, second, third and fifth paragraphs
 * — Transclude all paragraphs except the first
 * — Transclude all paragraphs except the second
 * — Transclude all paragraphs except the first and third
 * — Transclude all paragraphs except the first, second and third
 * — Transclude all paragraphs except the first, second, third and fifth
 * — Lists to transclude. By default all lists are transcluded.  Same syntax as when transcluding paragraphs.
 * — Files to transclude. By default all files are transcluded.  Same syntax as when transcluding paragraphs, but also:
 * — Transclude the file named 'A.jpg'
 * — Transclude the files named 'A.jpg', 'B.png</>' and '<tvar|3>C.gif</>'
 * — Transclude all PNG files
 * — Transclude all files except the one named '<tvar|1>A.jpg</>'
 * — Transclude all files except the ones named '<tvar|1>A.jpg</>', '<tvar|2>B.png</>' and '<tvar|3>C.gif</>'
 * — Transclude all non-PNG files
 * — Tables to transclude. By default all tables are transcluded.  Same syntax as when transcluding paragraphs, but also:
 * — Transclude the table with id '<tvar|1>Stats2020</>'
 * — Transclude the tables with ids '<tvar|1>Stats2020</>', '<tvar|2>Stats2019</>' and '<tvar|3>Stats2018</>'
 * — Transclude all tables except the one with id '<tvar|1>Stats2020</>'
 * — Transclude all tables except the ones with ids '<tvar|1>Stats2020</>', '<tvar|2>Stats2019</>' and '<tvar|3>Stats2018</>'
 * — Templates to transclude. By default all templates are transcluded.  Same syntax as when transcluding paragraphs, but also:
 * — Transclude the template '<tvar|1>Infobox</>'
 * — Transclude the template '<tvar|1>Infobox</>', '<tvar|2>Navbox</>' and '<tvar|3>Chart</>'
 * — Transclude all templates except '<tvar|1>Infobox</>'
 * — Transclude all templates except '<tvar|1>Infobox</>', '<tvar|2>Navbox</>' and '<tvar|3>Chart</>'
 * — Change the initial text of the hatnote. For example, if the transcluded content is a gallery, you can set <tvar|1> </> so that the hatnote reads "This gallery is an excerpt from..." (2>#Specific fragment</>|example).
 * — Hide the hatnote "This section is an excerpt from..."
 * — Keep bold text.
 * — Wrap the excerpt with <tvar|1> </> tags.
 * — Wrap the excerpt with <tvar|1> </> tags to use it inside other text.
 * — Remove all references.
 * — 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


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|1> Page </>.


 * 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|1> Subpage </> and leave an excerpt.
