Help:Transclusion

See also:Help:Page breaks

Transclusion displays the contents found on another page without having to copy-paste nor synchronize any later changes. It is most commonly used to group text into logical and reasonably sized chunks—most frequently as chapters or sections. Examine the transcluded text atThe Wind in the Willows (1913)/Chapter 1and compare with some of the source text found atPage:Wind in the Willows (1913).djvu/19.As the individual pages fromIndex:Wind in the Willows (1913).djvuwere saved in the "Page:" namespace, they populated into the chapters of the book through transclusion. Creating readable sections from scanned pages is the most common use of transclusion on Wikisource.

This help page first examines the most common methods of transclusion, this should be enough to help you manage your first texts. Next the page discusses more advanced and uncommon uses for transclusion which can stretch the digital text beyond familiar boundaries. And finally, it examines the full functionality of the two tranclusion methods. If you still have unanswered questions or any problems using transclusion, please post at theScriptoriumor atScriptorium (Help).Someone there will do their best to help you!

How to transclude full pages

You will most often be transcluding many pages together from thePage:namespace into the main presentation space of the wiki—as you saw atThe Wind in the Willows (1913)/Chapter 1.There are three methods which can perform full-page transclusion. The<pages/>function is preferred, while the {{Page}} template and the directtransclusionof a page from the page namespace also work but are discouraged. Most of the time, the <pages/> tag will be the best method of transcluding, but you may still run across the older template method when editing existing texts.

Where the pages to be transcluded would be placed inside another tag such as a<ref></ref>pair, then theMagic word#tag:pagesshould be used instead, with the relevant parameters translated accordingly.

The syntax for<pages/>is as follows:

<pagesindex="file name.djvu"from=xto=y/>

• "file name.djvu" is replaced with the exact name of the Index you are working with (donotinclude the "Index:" prefix).
• The number after the slash (/) following the file name of the first page you wish to transclude is "x".
• The number after the slash (/) following the file name of the final page you wish to transclude is "y".

Example

To display what is transcluded atThe Wind in the Willows (1913)/Chapter 5you would type:

<pagesindex="Wind in the Willows (1913).djvu"from=133to=161/>

How to transclude a portion of a page

Sometimes you will not want transclude a full page all together, examinePage:Popular Science Monthly Volume 25.djvu/169.When two chapters or logical sections appear on the same page, instead of the entire page you need a way to transclude only the relevant parts of the page into the main presentation space. The example page from above presents asPopular Science Monthly/Volume 25/June 1884/Modes of Reproduction in Plants.This is accomplished usingLabeled Section Transclusion(LST). The section breaks are marked with anchors in thePage:namespace. Then only the relevant part of the page, rather than the entire page, is called for during transclusion.

Adding section labels

To mark sections in the scan (Page:namespace), insert the following syntax into the typed proofreading text at the start of every new section^[1]:

## label ##

Alternatively you can use start<section begin= "label" />and end<section end= "label" />labels at the respective places in the text.

Note:

• Section tags are recommended to be wrapped in quotes"label"to avoid ambiguity.
• These are just free text labels, however, making labels contextual to the page can have advantages.
• Use of letters and numbers is usually a recommendation, and other extended characters may cause some issues when transcluding.
• Labels need to be unique on a page if they are referred to in a<pages/>tag, otherwise it can't be determinedwhichof the identically-named sections should be used.
• If you are using<poem>markers, please make sure to open and close theminsidethe sections, or else section transcluding will not work properly.

Transcluding to main namespace (file-based indexes)

The following applies to "file-based" indexes (ones that use DJVU or PDF files)

When the section ends part-way through a page

An extra parameter,tosection,is required in <pages> to end the transclusion at the anchor. The syntax is as follows:

<pagesindex="file name.djvu"from=xto=ytosection="label"/>

• file name.djvuis replaced with the exact name of the file you are working with. Donotinclude the "Index:" prefix.
• The number after the slash (/) following the file name of the first page you wish to transclude isx
• The number after the slash (/) following the file name of the final page you wish to transclude isy.
• labelis replaced with the name of the anchor you inserted.

Example

To display what is transcluded atPopular Science Monthly/Volume 25/June 1884/The Sins of Legislators IIyou would type:

<pagesindex="Popular Science Monthly Volume 25.djvu"from=155to=169tosection=E169/>

Handling spaces and punctuation in attribute values (the bit after the equals signs) is as usual for HTML:

• If the value of any attribute contains a space, wrap the whole value in straight quotes (either single or double).
• If the value contains a double quote, wrap the whole thing in single quotes:index=' "The Mummy" Volume 1.djvu'
• If the value contains a single quote, wrap in double quotes:index= "'Tis Sixty Years Since.djvu"
• If the value contains both singleanddouble quotes, wrap in double quotes and escape the double quotes in the value with",like this:index= "'Tis Sixty Years "Since".djvu"

When the section begins part-way through a page

To begin the first page of a chapter or section at the anchor, afromsectionparameter is needed. Follow this pattern:

<pagesindex="file name.djvu"from=xto=yfromsection="label"/>

Example

To display what is trancluded atPopular Science Monthly/Volume 25/June 1884/Modes of Reproduction in Plantsyou would type:

<pagesindex="Popular Science Monthly Volume 25.djvu"from=169fromsection=B169to=180/>

When the section begins and ends part-way through a page

If a section begins part way through one page and finishes part way through another, then bothfromsectionandtosectionparameters may need to be used at once:

<pagesindex="file name.djvu"from=xto=yfromsection="label"tosection="label"/>

Note, the "from" and "to" section names do not have to be the same. It is common for them to be the same, but not required.

Example

To display the sections used at "Bibliography of Chess Periodicals":

<pagesindex="Notes and Queries - Series 7 - Volume 12.djvu"from=150to=151fromsection="ContributionChessBiblio"tosection="ContributionChessBiblio"/>

When the section begins and ends on the same page

To transclude only a single section on a single page, you can use theincludeandonlysectionparameters:

<pagesindex="file name.djvu"include=Xonlysection="label"/>

Example

For example, just the contents onPage:Notes and Queries - Series 7 - Volume 12.djvu/149can be transcluded with:

<pagesindex="Notes and Queries - Series 7 - Volume 12.djvu"include=149onlysection=s1/>

Transcluding every other page

To transclude every other page (e.g. for a document with single-sided leaves), you can use thestepparameter:

<pagesindex="file name.djvu"from=Xto=Ystep=2/>

Example

For example, pages 6, 8, 10, 12 can be transcluded like this:

<pagesindex="Notes and Queries - Series 7 - Volume 12.djvu"from=6to=12step=2/>

Transcluding irregular sets of pages

Theincludeparameter can take a comma-separated list of page numbers, as well as page ranges in the formatX-Y.

<pages index= "file name.djvu" include= "A,B,C,X-Y" />

Example

For example, pages 6, 7, 8, 9, 10 and 42 can be transcluded like this:

<pagesindex="Notes and Queries - Series 7 - Volume 12.djvu"include="6-10,42"/>

fromsectionandtosectionalso work withinclude:they apply, as normal, to the first and last pages.

Transcluding to main namespace (image-based indexes)

For "image-based" indexes (i.e. ones constructed from a list of individual pages), onlyfromandtoare accepted by the<pages />tag:includeandexcludecannot be used (because filenames can include,and-).fromsectionandtosectionalso work.

Also, the pages are referred to by theirtitle,and not by their position in the index.

Example

For example, to transclude the title page ofIndex:Fourth Folio(position #9):

<pagesindex="Fourth Folio"from="Fourth Folio Miami University 009.jpg"to="Fourth Folio Miami University 009.jpg"/>

Transcluding sections without the page tag

Use of the<pages.../>tag as above is the preferred way to transclude sections of pages. However, this tag does not work on other Page: pages or in the Indexnamespace.On these pages, you can useLabeled Section Transclusion(LST) directly to transclude a section:

In this case, the following format can be used:

• {{#section:PageTitle|sectionA}}

• PageTitleis replaced with page you wish to transclude from (including thePage:namespace and/#numeric suffix as necessary)
• sectionAis the section you wish to transclude.

Deprecated method using {{Page}}

Another, deprecated, method is to use the {{page}} template, You may see this in some older works, but generally this template should no longer be used.

Use the {{Page}} template as follows, replacingdjvuwith the scan file name and#with the page number:

• {{Page|djvu/#|section=sectionA}}

How to place images with transcluded text

The preferred means of placing a picture or other image in the main pagespace is to upload the cropped image to Wikimedia Commons as a separate picture, for example as a png or jpeg file.

• [[File:Title and number and subject.png|frameless|center]]

The page image could also be displayed in the book's Wikisource mainspace like atPersonal Recollections of Joan of Arc/Book I/Chapter 2,using:

• [[File:Personal_Recollections_of_Joan_of_Arc.djvu|page=27|right|thumbnail|200px|{{uc|The Fairy Tree}}]]

Advanced usage

Transclusion can also be used to produce alternative displays of text without having to repeat the proofreading and validation.Celtic Fairy Tales/Guleeshpresents the story of Guleesh as published in Celtic Fairy Tales. It shows the preceding and following stories from that publication and also has a link to the foreword and commentary by the editor. AlternativelyGuleeshpresents the same text as a stand-alone work. Presenting suitable titles outside of the editions they may have been collected is not a necessary task any more than it is necessary to present a famous essay as a subpage of the magazine it happened to be printed in. However, both are possible by transcluding the same validated text. The consensus has been to allow individual editors to use whichever style they like inclusively.

Using the <pages/> function

Most of the time, the<pages/>tag will be the best method of transcluding. There is only one required parameter, which isindex=.This field must always be supplied or nothing happens. The exact pattern to use is as follows:<pages index= "file name.djvu" />where the namefile name.djvuis just a placeholder for whatever file you have used when proofreading.

Where the pages to be transcluded would need to be placed inside another a tag such as a<ref></ref>pair, then theMagic word#tag:pagesshould be used instead, with the relevant parameters translated accordingly. The parameters themselves have the same values and effects.

Try it out with a real file name: Copy

<pages index= "Wind in the Willows (1913).djvu" />

intohereand save. There is one other way to type this and have the same result. Try out<pages index=Wind_in_the_Willows_(1913).djvu/>.This works just the same. The important thing to know is that<pages index=Wind in the Willows (1913).djvu/>will not work. If you use any spaces in the field, then you must also surround the field with quotation marks ( "), or it will not work.

While you always must supply theindex=field, if you do not add any other parameters this syntax will only transclude the index of the file. Whenever you also supply some of the optional parameters, the index will be superseded by your other commands. Some of these optional parameters must be paired together in order to work. The numbers used in these fields are the titular number after the / in thePage:namespace. The optional parameters are as follows:

• from=(paired withto=) to supply the number of the first page to be transcluded
• to=(paired withfrom=) to supply the number of the last page to be transcluded
• fromsection=(paired withfrom=/to=orinclude=orexclude=) to supply the initial anchor on the first page of the section.

  The named sectionandany subsequent sections on the first page will be transcluded, all sections will be transcluded from the other pages

• tosection=(paired withfrom=/to=orinclude=orexclude=) to supply the final anchor on the last page of the section

  The named sectionandany previous sections on the last page will be transcluded, all sections will be transcluded from the other pages

• onlysection=(paired withfrom=/to=orinclude=orexclude=) to supply the anchor used to mark off a section for transclusion

  Only the named section will be transcluded, from all pages

• step=(paired withfrom=/to=orinclude=orexclude=) to supply a incremental number where every x page will be transcluded.

  Transclude every other page by increments of n. By example:<pages from= "1" to= "10" step= "2" />show the 1st, 3rd, 5th, 7th and 9th pages.

• includeprovides a list of one or more pages

  This allows a more flexible list. For example:<pages include= "2-5,9" />show the 2nd, 3rd, 4th, 5th and 9th pages.

  This is often used to transclude a single page, or a single section of a single page along withonlysection

• excluderemoves pages that would otherwise be included

  For example:<pages from=1 to=10 exclude= "2-5,9" />show the 1st, 6th, 7th, 8th and 10th pages.

• header=1

  Generates and inserts a {{header}} at the top of the page, using the information from theIndexpage. Seemw:Help:Extension:ProofreadPage/2013_draft#Headers_and_Navigationfor more details. This is an alternative to adding a manual header.

You can use all the attributes on the same tag. For example<pages from= "1" to= "10" include= "31" exclude= "2-4" step= "2" />will show 1st, 5th, 7th, 9th and 31st pages.

Note:Good practice says that attributes within the <pages> tag should be quoted. It is important tonothave unquoted empty attributes within tags, so please either quote empty attributes, or remove the unneeded optional attributes.

Considerations for Transcluded content

Certain mark-up (like table Syntax) must be entirely balanced across the Body sections of the pages transcluded. This either means that the markup or (rarer raw HTML used) must either be contained entirely within a single body or the approaches recommended atHelp:Page breaksutilised.

Layout

SeeHelp:Layout.

A Working, though deprecated Alternative

This is an alternative method, but should not be used unless there is a very good reason for not using the<pages/>tag.

The syntax for {{Page}} is as follows:

{{Page|file name.djvu/x|num=z}}

• "file name.djvu" is replaced with the exact name of the file you are working with.
• The number after the slash (/) following the file name of the page you wish to transclude is "x".
• The original corresponding page number from the scanned volume is "z".
• Note this can only transclude a single page at a time

Example

To display what is transcluded atThe Wind in the Willows (1913)/Chapter 5you would type:

{{Page|Wind in the Willows (1913).djvu/133|num=113}}
{{Page|Wind in the Willows (1913).djvu/134|num=114}}
{{Page|Wind in the Willows (1913).djvu/135|num=115}}
...
{{Page|Wind in the Willows (1913).djvu/161|num=141}}
