Transclusion/ja

参照読み込み (transclusion: トランスクルージョン) は、一般には特定の文書の内容を別の文書にリンクし参照させることです. ウィキの場合はのテンプレートの機能を用いて、同一の文書を複数の文書に読み込むことができ、読み込み先の文書をいちいち書き換える必要はありません. テンプレートのメッセージは多くの場合、テンプレートの参照読み込みにより表示され、実行にはテンプレートタグを以下のように使用します.

参照読み込みの仕組み


 構文

参照元が「Template:Welcome」のようにテンプレート名前空間にあるなら、リンク先を書きます.

もし参照元がメインの記事名前空間（「VisualEditor」のように）にあるなら、 その先頭に半角コロン を付けます.

その他（「User:Example」のような）名前空間にあるなら、参照元の名前空間から始まる長いリンクを書きます.

ソースがもしターゲットページの下位ページである場合 (例："Transclusion/ja")は名前空間に無関係に、下位ページの名前だけを提示します.



参照元ページを読みこみ先ページにトランスクルード（参照読みこみ）するには（ウィキペディアなど同一のMediaWikiプロジェクト内の場合）以下のコードを記述します.

翻訳文 A が処理されるたび、翻訳原文 B (ここではSOMEPAGEに相当) で参照読み込みタグを置いた箇所の全文が処理されます.

For example, you might decide to place a welcome message on every newcomer's talk page. Transclusion creates a "live" link between the template-page and the target-page(s) upon which the message should appear. When the template is edited, all the target-pages are edited too.

You might also decide to create a (template) page with your mailing address and include that template on not only your page, but all your friends' pages as well. When you move your television and couch to another apartment, you can change your address template, and that new information will automatically update on all your friends' pages.

語源
Ted Nelson coined the term "transclusion", as well as "hypertext" and "hypermedia", in his 1982 book Literary Machines.

部分的な参照読みこみ
By using "noinclude", "onlyinclude" and "includeonly" markup, it is possible to transclude part of a page rather than all of it. Such partial transclusions can also be achieved by transcluding from other pages such as subpages. It is often desirable not to transclude some information, such as template documentation and categories.

マークアップの方法

 * noinclude. The markup  means that the text between the tags will not be transcluded onto another page and will appear only on the page itself. This is useful for template documentation and categories.
 * includeonly. The markup  means that the text between the tags will only be used when the page is transcluded onto another page, and will not appear on the page itself. This can be useful, for example, for adding categories to pages transcluding a template, without adding the template itself to these categories.
 * onlyinclude. The markup  indicates that only text surrounded by "onlyinclude" markup should be transcluded onto another page, but will appear on the page itself if not accompanied by "includeonly" tags as well. This is the most subtle of the partial transclusion tags because it often overrules the others. If there is at least one pair of "onlyinclude" tags on a page, then whenever this page is transcluded, it is only the material within the "onlyinclude" tags which gets transcluded. There can be several such sections, and within each such section, some material might be further excluded by "noinclude" tags, and might also be surrounded by "includeonly" tags so that it does not appear on the original page itself. But material outside the "onlyinclude" tags will be ignored when the page is transcluded onto another page. This can be useful, for example, to repeat a small part of one page on a second one: just surround the small part by onlyinclude tags, and transclude it onto the second page. Note that unlike and,  will take precedence over enclosing  tags. In other words, My content produces only "My content" when transcluded.

下位ページ
You can cut and paste the text to be transcluded into a subpage, then use the name of the subpage in the transclusion template. This approach can be used only where subpages are enabled; for example, on the English Wikipedia, subpages can be used only from User, Talk or Wikipedia pages; currently, subpages cannot be created from main article pages.

Example: you want to discuss the deletion and redirecting of Pussycat to Cat. First, create the subpage Talk:Pussycat/Let's delete Pussycat!, write your comment into it, then transclude it in Talk:Pussycat and Talk:Cat using the template  . Comments posted in either talk page will be shown in both.

特別ページ

 * w:Wikipedia:TransclusionならびにManual:$wgAllowSpecialInclusionも参照

Some pages on Special:Specialpages can be transcluded, such as Special:AllPages, Special:PrefixIndex, Special:NewFiles, Special:NewPages, Special:RecentChanges and Special:RecentChangesLinked.

Sample: gives 3 new pages.

URL parameters can be given like template parameters, e. g..

テンプレートで代用するには
Occasionally you may want to use a template, but for one reason or another may not want to use transclusion. The automatic one-time copying of a template's code/text to the location of a template tag is called Template substitution or subclusion (substitution + transclusion). To subclude a template's code/text, the template tag is modified from the standard transclusion tag to a substitution tag, simply by adding subst:, creating a tag with the form:.

ラベル付き節の参照読みこみ
An extension called Labeled Section Transclusion enables marked sections of text to be transcluded. An extension with a somewhat similar function is PageVariableExtension.

意味論 MediaWiki
The Semantic MediaWiki extension uses inline queries to query and display semantic data. There are currently two ways to perform transclusion or something similar: See inline queries for further information.
 * 1) Transclusion proper. The display format "embedded" ensures that selected pages (mainspace articles, templates, etc.) are transcluded. As with templates, sections placed between noinclude tags will be omitted.
 * 2) Selected passages in a page can be assigned a property of type 'Text'. These selections can be requested by running an inline query for this type of property.
