The DynamicPageListEngine extension is a backend providing dynamic page lists, which can be used on php level for other extensions, or on Lua level with the Scribunto extension. The page selection and sorting criteria are compatible with DynamicPageList (Wikimedia).

Given that there are already DynamicPageList (Wikimedia) and DynamicPageList (third-party), which are not completely compatible, you might be wondering why yet another such extension. In short:

  1. I needed dynamic page lists on Lua level, and none of the two existing extensions provided that.
  2. Adding such a feature on top of DynamicPageList (Wikimedia) was not feasible due to its monolithic implementation.
  3. Adding such a feature on top of DynamicPageList (third-party) might have been possible, but then it would have been partially incompatible with the Wikimedia extension. More importantly, as the the DPL manual states, "DPL at the moment is rather monolithic" as well.
  4. Hence the only solution was to create a new extension from scratch.
  5. The extremely high number of features in the third-party extension suggests the need for a configurable, modular and extensible backend.

Kurulum

  • Dosyaları indirin ve extensions/ klasörünüzdeki DynamicPageListEngine adlı dizine yerleştirin.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/DynamicPageListEngine
  • LocalSettings.php dosyanızın altına aşağıdaki kodu ekleyin: 
    wfLoadExtension( 'DynamicPageListEngine' );
  • Yes Yapıldı – Uzantının başarıyla yüklendiğini doğrulamak için vikinizde Special:Version seçeneğine gidin.

Bu uzantı yalnızca MediaWiki 1.30 üzerinde test edilmiş olsa da, biraz daha eski sürümlerde de çalışması muhtemeldir.

Yükseltme

Yükseltmek için, en son sürümü kurmanız yeterlidir.

0.3 veya daha eski sürümden yükseltme

1.0.0 sürümü ile hemen hemen tüm yapılandırma parametreleri ve mesaj adları değiştirilmiştir. Bunlardan herhangi birini özelleştirdiyseniz, yapılandırmanızı uyarlamanız gerekir.

1.0.0 sürümünden beri, DynamicPageListEngine kullanan sayfalar bir izleme kategorisine ​​atanmaktadır. Zaten bu tür sayfalarınız varsa, kategorileri ya her sayfada bir boş düzenleme gerçekleştirerek veya $renewLinks betiğini çalıştırarak düzeltebilirsiniz. İkincisinin önemli miktarda zaman alabileceğini unutmayın.

Yapılandırma

LocalSettings.php

There is a number of parameters that can be customized in LocalSettings.php . The default configuration aims at maximum compatibility with DynamicPageList (Wikimedia) and is likely to satisfy your needs if you use this extension for the first time.

$wgDpleMaxCost
Maxiumum cost of a dynamic page list in terms of database load. The default value NULL means that it is automatically set to the corresponding value for DynamicPageList (Wikimedia).
$wgDpleMaxResultCount
Maxiumum number of records to fetch for one list. The default value NULL means that it is automatically set to the corresponding value for DynamicPageList (Wikimedia).
$wgDpleFeatures
Features to enable. An associative array between feature name/class and a boolean to indicate enabled (true) or not (false). See Usage for details. You should always enable at least DpleFeatureCount, otherwise there is no limit to the number of fetched records, and DpleFeatureCheck, otherwise there is no limit on the complexity of the query. If you want to use Lua, you also need DpleFeatureResults. Each of these may be replaced with a derived class or a class with similar semantics.:: The default list of features may be viewed in the extension's extension.json.
$wgDpleCondCostMap
Cost of selection conditions in terms of database load. A unit of 1 should correspond to an efficient table join. You can tune this map to reflect the real cost on your particular installation and/or prevent users from excessive use of certain features.
$wgDpleOrderCostMap
Cost of order methods in terms of database load, in units which should be vaguely comparable to those of $wgDpleCondCostMap.

Unless you are very concerned about performance issues, you may simply enable all features in $wgDpleFeatures by copying it from the file DynamicPageListEngine.php any uncommenting everything. In that case, to limit performance impact, you might decide to set $wgDpleMaxCost to a low value which however permits to use each feature, for instance 3.

Mesajlar

Uzantı, daha fazla gelişme ile sürekli gelişen birçok mesajı tanımladığından, bunlar burada belgelenmemiştir. Lütfen i18n/qqq.json sayfasına bakın.

Kullanım

For use on php level, please refer to the integrated doxygen documentation. For use on Lua level, see Lua library.

The accepted parameters and other aspects of the behaviour are implemented as features corresponding to php classes. With the variable $wgDynamicPageListEngineFeatures in LocalSettings.php you can configure which features you want to enable. The bundled features are described in the following sections, where the titles correspond to the class names without the prefix "DynamicPageListEngineFeature".

Unless otherwise stated, using arrays as parameter values return the intersection of the individual result sets. If the parameters contradict each other (e.g. the same namespace is nominated in namespace and in not namespace), the results are undefined.

Namespace

Select by namespace. Recognizes the parameters namespace and notnamespace which may be a namespace name or namespace index or an array thereof. Any invalid value, including the empty string, is interpreted as the main namespace, for compatibility with DynamicPageList (Wikimedia).

If namespace is an array, the result set consists (obviously) in the pages in any of the namespaces, i.e. the result set is the union of the individual result sets, unlike other parameters (including notnamespace) where the result set is the intersection.

Category

Select by category. Recognizes the parameters category and notcategory. Each of them may be a string or an array. If category is an array, the result set consists in the pages contained in all listed categories. If notcategory is an array, the result set consists in the pages contained in none of the listed categories.

Redirects

Include or exclude redirects. Recognizes the parameter redirects, which may be one of exclude|include|only|resolve.

Default is exclude, for compatibility with DynamicPageList (Wikimedia).This implies that enabling this feature in $wgDynamicPageListEngineFeatures will change the result set of a dynamic page list even for parameter sets which do not contain the redirects parameter, if the result set would contain redirects.

The value resolve selects only redirects just like only, but in addition the target for each redirect is retrieved. This means that the result objuect for each page has a property target which is an associative array of properties of the redirect target.

Titlematch

Select by title prefix, suffix or fragment. Recognizes the parameters titleprefix, nottitleprefix, titlesuffix, nottitlesuffix, titlecontains and nottitlecontains, each of which may be a title substring or an array thereof. As usual, spaces and underscores in titles are equivalent.

If titleprefix, titlesuffix, titlecontains is an array, the result set consists (obviously) in the pages satisfying any of the conditions, i.e. the result is the union of the individual result sets, unlike other parameters (including nottitleprefix) where the result set is the intersection.

This class implements a [not]title{prefix suffix contains} condition for substrings, but not a general [not]titlematch for LIKE patterns, because escaping of the % and _ characters depends on the database backend and hence it could not be ensured that a condition containing these metacharacters supplies the same result on all database backends.

Subpages

Include or exclude subpages. Recognizes the parameter subpages, which may be one of exclude|include|only. Default is exclude, for consistency with the Redirects feature.

This implies that enabling this feature in $wgDynamicPageListEngineFeatures will change the result set of a dynamic page list even for parameter sets which do not contain the subpages parameter, if the result set would contain subpages.

Subpage selection works with a simple LIKE '%/%' expression, regardless of whether the namespace of a page has subpages enabled. To distinguish whether subpages are enabled, a CASE expression or something similar would need to be evaluated for each single row, and it would be difficult to implement this in an efficient and portable way.

Linksto

Select pages linking to the specified pages. Recognizes the parameters linksto and notlinksto. Each of them may be a string or an array. The result set differs from the result of "What links here" because it does not contain redirects, for compatibility with DynamicPageList (third-party).

Linksfrom

Select paged linked from specified pages. Recognizes the parameters linksfrom and notlinksfrom. Each of them may be a string or an array. The names are chosen for compatibility with DynamicPageList (third-party).

Redirectsto

Select pages redirecting to the specified pages. Recognizes the parameters redirectsto and notredirectsto. Each of them may be a string or an array.

Uses

Select pages using the specified pages as templates. Recognizes the parameters uses and notuses. Each of them may be a string or an array. The results are the same as with DynamicPageList (third-party).

Usedby

Select pages used as templates by the specified pages. Recognizes the parameters usedby and notusedby. Each of them may be a string or an array. The results are the same as with DynamicPageList (third-party).

Imageused

Select pages that contain the specified images. Recognizes the parameters imageused and notimageused. Each of them may be a string or an array. The names are chosen for compatibility with DynamicPageList (third-party).

Imagecontainer

Select images that are contained in the specified pages. Recognizes the parameters imagecontainer and notimagecontainer. Each of them may be a string or an array. The names are chosen for compatibility with DynamicPageList (third-party).

Contains

Select categories which contain the specified pages. Recognizes the parameters contains and notcontains. Each of them may be a string or an array.

Extra

Select pages by extra information in category tags. You can add extra information in a category sort key, in constructs like [[Category:...|user:{{PAGENAME}}|head of team]]. For MediaWiki, the whole string user:{{PAGENAME}}|head of team is the sort key. The extension considers the part after the second pipe character (head of team in the example) as extra information.

The feature recognizes the parameters extra and notextra. extra selects exact matches of the extra information appended to the sort key for the first category specified with the category parameter. notextra selects the complement of this. If no categories are selected, these parameters are silently ignored.

If extra is an array, the result set consists (obviously) in the pages satisfying any of the conditions, i.e. the result is the union of the individual record sets, unlike other parameters (including notextra) where the result set is the intersection.

Extrax

Select categories by extra information in category tags.

The feature recognizes the parameters extrax and notextrax. extrax selects categories with exact matches for the extra information appended to the sort key for the first page specified with the contains parameter. notextrax selects the complement of this. If no contains parameter was used, these parameters are silently ignored.

If extrax is an array, the result set consists (obviously) in the pages satisfying any of the conditions, i.e. the result is the union of the individual record sets, unlike other parameters (including notextrax) where the result is the intersection.

User

Selection by modifying user. Recognizes the parameters createdby, notcreatedby, modifiedby, notmodifiedby, lastmodifiedby and notlastmodifiedby, each of which may be a title substring or an array thereof.

If createdby, modifiedby, lastmodifiedby is an array, the result set consists in the pages satisfying any of the conditions, i.e. the result is the union of the individual record sets, unlike other parameters (including notcreatedby) where the result is the intersection.

Use of [not]modifiedby is likely to create much more database load than the other parameters because the record sets to join may be very large. This is reflected in $wgDynamicPageListEngineCondCostMap, but you might need to adjust this value. You can effectively disable these parameters by setting their cost higher than the value of $wgDynamicPageListEngineMaxCost.

Count

Limit the number of records to fetch from the database. Recognizes the parameter count which gives the limit. Invalid values (including 0) are interpreted as 1, for compatibility with DynamicPageList (Wikimedia). In any case, the number is limited to $wgDynamicPageListEngineMaxResultCount.

Order

Sort the result records. Recognizes the parameters order (default descending) and ordermethod (default categoryadd). Some values are replaced by fallback values if no category was indicated. Defaults and fallback values are chosen for compatibility with DynamicPageList (Wikimedia).

In addition to the ordermethod values recognized by DynamicPageList (Wikimedia), the value title is accepted as well. It sorts by title without namespace prefix.

Check

Check whether the whole specification is acceptable in terms of database load.

Results

Convert query results to other representations. See Lua library for details.


Lua library

All functions explained below take a single argument which is an associative array of parameters. The recognized parameters are explained in Usage.

mw.ext.dpl.getFullpagenames

mw.ext.dpl.getFullpagenames{ parameters }

Select and sort pages according to the parameters and return an array of full page names.

mw.ext.dpl.getPagenames

mw.ext.dpl.getPagenames{ parameters }

Select and sort pages according to the parameters and return an array of page names without namespace. This is useful if you know the namespace in advance because you have specified it in the arguments.

mw.ext.dpl.getPages

mw.ext.dpl.getPages{ parameters }

Select and sort pages according to the parameters and return an array of associative arrays, each of which represents a page. The latter contain the following items which have the same meaning as the corresponding properties of mw.title objects: namespace, nsText, text, prefixedText, baseText, subpageText, canTalk, isContentPage, isSubpage, isTalkPage, isRedirect. In addition, the following items are provided:

length
Uncompressed length in bytes of the page's current source text.
categoryadd
Timestamp of addition to the first category specified with the category parameter, if any.
categoryaddx
Timestamp of addition of the first page specified with the contains parameter, if any, to the selected category.
counter
Page view counter, unless counters are disabled.
sortkey
Sort key in the first category, if any, provided that DynamicPageListEngineFeatureExtra is enabled.
extra
Extra information given with sort key, if any, provided that DynamicPageListEngineFeatureExtra is enabled.
sortkeyx
Sort key in the category of the first page specified with the contains parameter, if any, provided that DynamicPageListEngineFeatureExtrax is enabled.
extra
Extra information given with the sortkeyx sort key, if any, provided that DynamicPageListEngineFeatureExtrax is enabled.
