<languages/> テンプレート:TNT 複数のページに含めたい共通するようなテキストがある場合、MediaWiki のテンプレート機能が役立ちます。 Unlike extensions and media files, there is no central repository for templates. Templates can be newly written or to save duplicating work already done, exported from another wiki e.g. Wikipedia, and then imported into the target wiki.

作成

Templates are standard wiki pages whose content is designed to be transcluded (embedded) inside other pages. Templates follow a convention that the name is prefixed with "Template:", assigning it to that namespace; besides this, you can create them like any other wiki page.

The simplest use of templates is as follows. If you create a page called "Template:Welcome" with contents:

こんにちは! ウィキへようこそ。

you'll have created your first template! If you then insert the code:

{{Welcome/ja}}

in any other page, when that page is viewed the text "Hello! Welcome to the wiki." will appear instead of {{Welcome}}. The template content is "transcluded" into the other page, i.e. it is integrated in the page.

You can then insert {{Welcome}} at any point of any page where you wish to welcome someone. Suppose it is used in 100 pages. If you then change the template contents to:

Hi there! Welcome to this wonderful wiki.

and revisit any of the 100 pages where the template was used, you'll see the new text instead of the original one. In this way, you have changed the content of 100 pages without editing them, because the template is transcluded into these pages.

This is the basic mechanism. There are several additional features of transclusion that enrich this mechanism and make templates very useful.

使用

テンプレートは、他のページ内で以下のように使用できます:

• {{Name}} — as described above, this link will be dynamically replaced by the current content of [[Template:Name]] at the time the page with the template link is loaded. The link will remain unchanged in the page's source.
• {{subst:Name}} — when this template link is used, it will be replaced once and for all with the content of [[Template:Name]] as of the time the page with the link is saved: a copy of the contents of [[Template:Name]] will be substituted for the template link. The contents are then a part of the including page, and can be edited normally, separately from the original. Note: changes to the source template page will not be propagated to the page with the template link.
• {{safesubst:Name}} — this was introduced to allow for substitution that doesn't break transclusion, see w:en:Help:Substitution#The safesubst: modifier.
• {{msgnw:Name}}は、それを含むページが取得されるときに、<nowiki>のように生のwiki構文として表示する形式でテンプレートを埋め込みます。

In fact, an ordinary wiki page can also be used as a template, simply by specifying the namespace it resides in, so:

• {{Template:ページ名}} は [[Template:ページ名]] を参照読み込みします
• {{Foo:ページ名}} は [[Foo:ページ名]] を参照読み込みします
• {{:ページ名}} は [[ページ名]] を参照読み込みします
  • {{subst::Pagename}} replaces itself with the contents of [[Pagename]]

If no such namespace exists, the full title is assumed to be a template:

• {{Foo:Bar}} includes [[Template:Foo:Bar]]

パラメーター

To enrich the mechanism of transclusion, MediaWiki allows parameters to be passed to a template when it is transcluded. Parameters allow the template to produce different contents or have different behaviors.

Suppose you wish to insert a little thank you note in the talk page of other users, such as:

The thank you note will have a reason (in this case, "all your effort") and a signature ("Me"). Your objective is that any user is able to thank any other user, for any reason whatsoever.

So that the note will look similar everywhere it is used, you can define a template called Template:Thankyou, for example. Although the note should look similar whenever a user thanks another user, its specific contents (i.e. the reason and the signature) will be different. For that reason, you should pass them as parameters. If we ignore the remaining elements to format the box and place the image, the core content of the template will be this:

'''A little thank you...'''
for {{{1}}}.
hugs, {{{2}}}

Notice the use of {{{1}}} and {{{2}}}. This is the way to identify, within templates, the parameters that will be passed in when the template is used. Note that, within the template, each parameter is surrounded by three braces: {{{ }}}. This is different from normal template name usage.

When using the template on a page, you fill in the parameter values, separated by a "pipe" character (|). MediaWiki allows parameters to be passed to the template in three ways: Anonymously, Numbered, and Named.

名前なしパラメーター

To pass in anonymous parameters, list the values of those parameters sequentially:

{{Thankyou|all your effort|Me}}

In this case, the {{Thankyou}} template receives parameters {{{1}}}=all your effort and {{{2}}}=Me, producing:

The order in which anonymous parameters are passed in is crucial to its behavior. Reversing the order of the parameters, like so:

{{Thankyou|Me|all your effort}}

would produce this result:

Note: identifying parameters by order (with {{{1}}}, etc) works only with anonymous parameters. If your page identifies any parameter by number or name, as shown below, this method will no longer be available to the template which receives them.

番号のパラメーター

To pass in parameters by number, identify each parameter when passing it:

{{Thankyou|2=Me|1=your friendship}}

This time, template {{Thankyou}} receives parameters {{{1}}}=your friendship and {{{2}}}=Me, though they have been supplied in inverse order, and produces:

名前のパラメーター

The third way of passing parameters is by name, instead of numbers. In this case, the template contents would be changed to:

'''A little thank you...'''
for {{{reason}}}.
hugs, {{{signature}}}

Within the template, we use {{{reason}}} and {{{signature}}} to identify each parameter, instead of a number. To pass these parameters by name, identify each parameter when passing it:

{{Thankyou|signature=Me|reason=being who you are}}

In this case, template {{Thankyou}} receives parameters {{{reason}}}=being who you are and {{{signature}}}=Me and produces:

The advantage of using named parameters in your template, besides also being flexible in the order parameters can be passed, is that it makes the template code much easier to understand if there are many parameters.

既定値

If you transclude a template that expects parameters, but do not provide them, in this way:

{{Thankyou}}

in the numbered parameters example above you would get the following:

Since no parameters were passed in, the template presents the parameters themselves, instead of their respective values. In these cases, it may be useful to define default values for the parameters, i.e. values that will be used if no value is passed in. For example, if the template contents are changed to:

'''A little thank you...'''
for {{{reason|everything}}}.
hugs, {{{signature|Me}}}

then {{{reason|everything}}} defines that if no parameter {{{reason}}} is provided, then the value everything will be used. Similarly, {{{signature|Me}}}, defaults parameter {{{signature}}} to value Me. Now, transcluding the template again without passing any parameter, results in the following:

テンプレートの参照読み込みの制御

By default, a template's content is displayed in its entirety, both when viewed directly and when included in another page. However, you can control which parts of a template will be seen and included by the use of the <noinclude> and <includeonly> tags.

<noinclude>と</noinclude>の間にあるものはページが直接閲覧されるときのみ表示され、インクルードされる場合は表示されません。実行できる応用例は次の通りです:

• テンプレート自身をカテゴリ化する際に使用するカテゴリ
• 他言語版の類似したテンプレートへの言語間リンク
• テンプレートの使用法についての説明文

逆は<includeonly>.です。<includeonly>と</includeonly>の間のテキストはページがインクルードされたときのみ処理され表示されます。明確な応用例は与えられたテンプレートを含むすべてのページをカテゴリに追加することです。

• Categorizing pages which include the template. Note: when changing the categories applied by a template in this fashion, the categorization of the pages which include that template may not be updated until some time later: this is handled by the {{ #ifeq:

 獣医志Wiki

| MediaWiki | job queue | [[{{#if:|{{#ifexist:Manual:Job queue||mw:}}}}Manual:Job queue|job queue]] }}. To force the re-categorization of a particular page, open that page for editing and save it without changes.

• Ensuring that the template's code is not executed when viewing the template page itself. Typically this is because it expects parameters, and its execution without parameters has an undesired result.

Everything outside <noinclude> and <includeonly> tags is processed and displayed normally; that is, both when the template page is being viewed directly and when the template is included in another page.

テンプレートの整理

テンプレートを効率的にするために、ユーザがそれらを見つけ利用できることが必要です。

以下の方法で見つけられます:

1. 特別ページ' > 全ページをクリック
2. 名前空間:一覧で、Template を選択して表示

To give usage information, include an example like this one on the template page:

<noinclude>
== Usage ==
Welcome users:
{{Thankyou|reason=your reason|signature=your signature}}
</noinclude>

それから編集者は同じようなページを作成するために例をコピー＆ペーストします。

別のウィキへのコピー

Templates often require CSS or other templates, so users frequently have trouble copying templates from one wiki to another. The steps below should work for most templates.

MediaWiki のコード

If you have import rights (Specifically importupload) on the new wiki:

1. Go to Special:Export on the original wiki, and download an .xml file with the complete history of all necessary templates, as follows:
   • Enter the name of the template in the big text box, e.g. "Template:Welcome". Pay special attention to capitalization and special characters — if the template name isn't exactly correct, the export may still occur but the .xml file will not have the expected data.
   • ボックス「テンプレートを含める」にチェックを入れる。
   • ボックス「完全な履歴は含めず、最新版のみを含める」のチェックを外す。
   • 「書き出し」をクリック。
2. Go to Special:Import on the new wiki and upload the .xml file.

If you don't have import rights on the new wiki:

1. Go to the template you want to copy from the original wiki. Go to the edit page, and copy all the wikitext
2. On the new wiki, go to the page with the same name as the template you copied. Hit create/edit and paste the wikitext you copied. In the edit summary of each template, link to the original page for attribution.
3. Back in the original wiki at the edit window, below the edit box, look at the list of "Templates used on this page". For each template listed follow these instructions. Also do that for any template used by any of these templates, and so on.

This will copy the entire code necessary, and will suffice for some templates. If it doesn't work also check for red links listed under "Pages transcluded onto the current version of this page:", below the edit box. If there are any repeat the above steps for these as well.

After sucessfully importing the template and all its linked templates from the other wiki, edit it to change customisations to suit your wiki. For example to change a logo, remove redundant categories or red links.

拡張機能

An extension often used in templates is ParserFunctions. Visit page {{ #ifeq:

 獣医志Wiki

| MediaWiki | ParserFunctions | [[{{#if:|{{#ifexist:Help:Extension:ParserFunctions||mw:}}}}Help:Extension:ParserFunctions|ParserFunctions]] }} and check if any of the functions listed there are used in the templates you've copied. If so, you have to install the {{ #ifeq:

 獣医志Wiki

| MediaWiki | ParserFunctions extension | [[{{#if:|{{#ifexist:Extension:ParserFunctions||mw:}}}}Extension:ParserFunctions|ParserFunctions extension]] }}. To install it, you'll need system admin access to the server of your MediaWiki installation.

Another dependency that may be used in templates, especially those on Wikipedia, is Lua. Having {{#invoke: }} in template code is a good sign for it. In case it's used, you need to install the {{ #ifeq:

 獣医志Wiki

| MediaWiki | Scribunto extension | [[{{#if:|{{#ifexist:Extension:Scribunto||mw:}}}}Extension:Scribunto|Scribunto extension]] }} and system admin access is required too. See that page for more instructions about installing and using the extension.

CSS および JavaScript のコード

Besides MediaWiki code, many templates make use of CSS and some rely on JavaScript to work fully. If the copied templates are not behaving as expected, this may be the cause. To copy the required CSS and JavaScript to your wiki you'll normally need to have admin privileges, because you'll be editing system messages in the "MediaWiki:" namespace.

1. Look for the use of CSS classes (text like class="foobar") in the template text. If those classes appear in "MediaWiki:Common.css" or "MediaWiki:Monobook.css" on the original wiki, copy those classes to "MediaWiki:Common.css" on the new wiki and check if the template is now fine.
2. If the copied template is still not working as expected, check if there is code in "MediaWiki:Common.js" or "MediaWiki:Monobook.js" on the original wiki. If so, you can try copying it to "MediaWiki:Common.js" on the new wiki. Normally, it is a good idea to only copy code from trusted sources, and first browsing the code to identify and select the parts that are relevant. You may find comments that can serve as clues to identify the functionality of each part.
