The DynamicPageList (third-party) extension is a reporting tool for MediaWiki, listing category members and intersections with various formats and details. For full documentation, see the full original manual or manual (German Manual Hilfe:DynamicPageList).

最も基本的な形として、DPL は 1 つまたは複数のカテゴリに分類されたページのリストを表示します。 また、著者、名前空間、日付、名前のパターン、テンプレートの使用、他の記事への参照などの要素に基づいて選択されることもある。 アウトプットの形は様々で、中には厳選された記事の要素を取り入れたものもあります。

この拡張機能は、パーサ関数{{#dpl: .... }}またはパーサタグ‎<DPL>で呼び出される。 A Wikimedia-compatible implementation of certain features can be invoked with ‎<DynamicPageList>.

DPL can result in computationally-expensive database queries. For best performance, use the optional parameters allowcachedresults and/or dplcache where possible.

インストール

LocalSettings.php must not include Wikimedia's version of DPL (Intersection).

• ダウンロードして、ファイルをextensions/フォルダー内のDynamicPageListという名前のディレクトリ内に配置します。
• 以下のコードを LocalSettings.php の末尾に追加します:

  require_once "$IP/extensions/DynamicPageList/DynamicPageList.php";
  

• 必要に応じて設定を変更
•  完了 – ウィキの「Special:Version」に移動して、拡張機能が正しくインストールされたことを確認します。

During the installation process a template is automatically created. If you are getting error messages about how user in the "users" group does not have permissions, it probably has something to do with the installer "user" does not have permission to create a template. In order to install the extension, you may need to temporarily open up page creation permissions and then turn them off after the extension is installed.

設定

DPL configuration settings and their default values, from the manual:

設定	既定	説明
ExtDynamicPageList::$allowedNamespaces	null	To be initialized at first use of DPL, array of all namespaces except Media and Special, because we cannot use the DB for these to generate dynamic page lists. Cannot be customized. Use ExtDynamicPageList::$options['namespace'] or ExtDynamicPageList::$options['notnamespace'] for customization.
ExtDynamicPageList::$allowUnlimitedCategories	true	Allow unlimited categories in the Query
ExtDynamicPageList::$allowUnlimitedResults	false	Allow unlimited results to be shown
ExtDynamicPageList::$behavingLikeIntersection	false	Changes certain default values to comply with Extension:Intersection
ExtDynamicPageList::$categoryStyleListCutoff	6	Max length to format a list of articles chunked by letter as bullet list, if list bigger, columnar format user (same as cutoff arg for CategoryPage::formatList())
ExtDynamicPageList::$fixedCategories	empty array	categories has been used
ExtDynamicPageList::$functionalRichness	0	The amount of functionality of DPL that is accesible for the user; to be set by DynamicPageList.php and DynamicPageListMigration.php see the fixcategory command
ExtDynamicPageList::$maxCategoryCount	4	Maximum number of categories allowed in the Query
ExtDynamicPageList::$maxResultCount	500	Maximum number of results to allow
ExtDynamicPageList::$minCategoryCount	0	Minimum number of categories needed in the Query
ExtDynamicPageList::$options	no options	If you add a line like the following to your LocalSettings.php, DPL will only run from protected pages: ExtDynamicPageList::$options['RunFromProtectedPagesOnly'] = "Extension DPL (warning): current configuration allows execution from protected pages only."; There is a whole bunch of other options too; see DPLSetup.php.
ExtDynamicPageList::$respectParserCache	false for <dpl> but true for <DynamicPageList>.	If set to 'true' DPL will no longer behave dynamically because its output is taken from the ParserCache. In other words, false = make page dynamic ; true = execute only when parser cache is refreshed

These are all public static variables.

The global variable $wgNonincludableNamespaces is also respected by DPL. It will prevent the contents of the listed namespaces from appearing in DPL's output.

$maxResultCount is a LIMIT on the SQL query itself. Some DPL query parameters like includematch are applied after the SQL query, however, so results here may easily be misleading.

機能の豊かさ

DynamicPageList has many features; some are expensive, or dangerous in the wrong hands. It is important to choose an appropriate level of functionality for your wiki.

• ExtDynamicPageList::setFunctionalRichness(0) is equivalent to Wikimedia's DPL
• ExtDynamicPageList::setFunctionalRichness(1) adds additional formatting parameters
• ExtDynamicPageList::setFunctionalRichness(2) adds performance equivalent features for templates and pagelinks
• ExtDynamicPageList::setFunctionalRichness(3) allows more-expensive page inclusion features and regular expression queries; expect to use the dplcache parameter
• ExtDynamicPageList::setFunctionalRichness(4) permits exotic and potentially dangerous batch update and delete operations; not recommended for public websites

The Functional Richness grouping described above is a built-in suggestion; it can easily be adapted to your own preferences within "DPLSetup.php".

使用法

拡張された DPL 機能

Extended DPL is invoked by using the parser function {{#dpl: .... }}, or the parser extension tag ‎<DPL>...‎</DPL>.

See: Manual - General Usage and Invocation Syntax and Manual - DPL parameters

後方互換性がある機能

Functionality compatible with Wikimedia's DPL extension can be invoked with <DynamicPageList> .... </DynamicPageList>.

概要

Assume you have written some articles about countries. Typically these articles will have three things in common:

• They will belong to a common category
• They will have a similar chapter structure, i.e. they will contain paragraphs named 'Religion' or 'History'
• They will use a template which is used to present highly structured short data items ('Capital', 'Inhabitants', ..) in a nice way (e.g. as a wikitable)

DPLは、記事に関するレポートを作成します

Let us assume that there is an article on Islam. You want to give some information about the spreading of this religion over various countries. But you do not want to create redundancy by repeating information that was already given in the articles on the countries.

In our scenario the natural approach with DPL would be to generate a list of 'countries' (=category) where Islam plays a role (i.e. restrict your selection to articles of category 'Country' which contain a link to 'Islam'). Typically you would want to include part of the text chapter on 'Religion' from each of the relevant countries. You might also want to give the number of inhabitants for each country. The output should be shown as an alphabetically ordered table. It would be nice if the user could easily sort the table by inhabitants or some other criteria.

With DPL you can ..

• generate a list of all those articles (or a random sample)
• show metadata of the articles (popularity, date of last update, ..)
• show one or more chapters of the articles ('transclude' content)
• show parameter values which are passed to the common template
• order articles appropriately
• present the result in a sortable table (e.g.)
• use multi column output

どのような手順が必要なのでしょうか？

Find the articles you want to list:

• select by a logical combination (AND,OR,NOT) of categories
• specify a range for the number of categories the article must be assigned to
• select by a logical combination (AND,OR,NOT) of namespaces
• define a pattern which must match the article's name
• name a page to which the article must or must not link
• name a template which the article must or must not use
• name a text pattern which must occur within external links from a page
• exclude or include redirections
• restrict your search to stable pages or quality pages ("flagged revisions")
• use other criteria for selection like author, date of last change etc.
• define regular expressions to match the contents of pages you want to include

Order the result list of articles according to

• name
• date of last change
• popularity
• user who changed them last
• size
• restrict the output to the first n articles or to a random sample
• use descending or ascending sequence

Define attributes you want to see

• article name
• article namespace
• article size
• date of last change
• date of last access
• user who changed them last

Define contents you want to show

• whole article
• contents of certain chapters (identified by headings)
• text portions (defined by special marker tags in the article)
• values of template calls
• substitute the original template by a different one and show the output of that template

Define the output format

• specify headline and footer for your report
• use ordered list, unordered list
• use tables, sorted tables (using javascript)
• format table fields individually by applying templates to their content
• use category style listing
• create "tag clouds" by varying output text size depending on popularity of pages
• multi column output
• truncate title or contents to a certain maximum length
• add a link to the article or to one or more of its chapters

DPLは、カテゴリに関するレポートを作成します

Apart from producing a list of pages which match certain criteria, DPL can also create a list of categories a selected set of pages belongs to. This can be useful to get an idea of the semantic scope of a group of pages (which can be defined by some arbitrary criteria). One of the more useful applications would be question like: "To which categories do the pages belong which contain a reference to the current page?"

DPLを使った一括編集が可能

Sometimes you want to perform a similar editing task on many articles (like adding a template at the beginning of the text). DPL has a feature which allows you to update other articles based on regular expressions. This feature is experimental and can be disabled in the DPL config file.

DPLは他の拡張機能と相互作用します

There is a special mechanism which allows you to call your own extension inside the result loop of a DPL query. This opens doors for assembling new 'applications' without having to program on php level. For example you can create menu trees for Extension:Treeview, you can create dependency graphs or timebars with Extension:Wgraph, you can generate nice bar graphs or pie charts using DPL together with Ploticus, you can call 'gallery' or whatever you want...

DPLは他のアプリケーションを構築するためのプラットフォーム

The power of DPL makes it possible to create applications on wiki template level which would normally require PHP programming. One example of this is a light-weight "semantic wiki" approach. See the DPL demo page for details.

DPLとパフォーマンス

With a few lines of DPL code it is possible to create huge output and CPU load (think of a DPL query which tries to include the contents of all articles in your mediawiki ;-)). Normally this is not a problem because users who write DPL queries have some level of expertise. If you are afraid, however, you can restrict the execution of DPL queries to protected articles.

Apart from that the general performance of DPL on medium-size wikis is quite acceptable (see the performance tests on the dpldemo website). Use of allowcachedresults and/or dplcache where possible can improve performance.
