Revision as of 22:19, 24 June 2009

PLEASE DO NOT DOWNLOAD DPL 1.8.5 !
Unfortunately it contains a severe bug (ambiguous SQL statement created).
you can take 1.8.4 (June 15, 2009) from the archive  instead.

Version 1.8.5

There are some internal technical changes in this release and some performance improvements which make scrolling throuh huge result sets faster. IN addition there are some new features regarding the include statement.

include now understands parserFunctions

using include={#xxx}.abc allows to find the calls of parser functions and their arguments

include now understands tag functions

using include={~xxx}.abc allows to find extension calls which use tag syntax

scrolling greatly improved

added special logic to DPL_fromTitle: reversed sort order for backward scrolling

new parameters for scrolling

title< and title>

new URL args for scrolling

DPL_fromTitle, DPL_toTitle

new built-in vars for scrolling

 %FIRSTTITLE%, %LASTTITLE%, %FIRSTNAMESPACE%, %LASTNAMESPACE%, %SCROLLDIR% (only in header and footer)

internal changes

changed the php source files to UTF8 encoding (i18n was already utf8); removed all closing php tags at the end of the source files; added 'path' and changed href to "third-party" in the hook-registration; changed implementation of userdate transformation to wgLang->userAdjust()

bugfix at date display

added a space after display of dates in 'addeditdate' etc.

bugfix collation problem

removed replacement of card suit symbols in SQL query due to collation incompatibilities

changed default ordermethod

DPL now uses 'titlewithoutnamespace as default (as this is more efficient than 'title'); this may affect the output of existing queries; add 'ordermethod=title' to keep the current ordering

Version 1.8.4

new command linkstoexternal

now you can also search for external links contained in your articles

new command addexternallink

displays external links which were found according to your query; the variable %EXTERNALLINK% can be used for the same purpose.

new ordermethod

none - as the name says this option will suppress ordering of the result set

bugfix in titlematch

up to now spaces in a pattern had been translated to underscores because MW stores underscores instead of spaces. As an underscore is a wildcard symbol in a SQL-LIKE-expression (it stands for an arbitrary character) this was not correct. Now we translate to an escaped underscore.

userdateformat

default value changed to show also seconds (not only Y-m-d H:i)

bugfix date/time

in some cases (anonymous users, older MW revisions) a completely wrong date was displayed (year 1977 ..)

date/time used for selection in revsion-related selctions

these now are translated by the timezone so that they fit with the server time.

bugfix SQL error

the combination of 'title' and 'allrevisionssince' led to a SQL error.

performance info improved

 %DPLTIME% now shows fractions of seconds

Version 1.8.3

bugfix in expansion of URL parameters

execandexit did not work correctly in some constellations

Version 1.8.2

bugfix %DATE% 

when using addeditdate=true and ordermethod=lastedit and minoredits=exclude the built-in variable %DATE% was not expanded

policy change in dynamic behaviour

somewhen after revision 1.7.4 the caching strategy of DPL was changed. This lead to the effect that DPL pages were in some constellations no longer 'dynamic', i.e. the MW parser cache had to be deleted (via &action=purge) to see the latest results. While this may seem preferable for really large sites it may confuse people on smaller an medium size wikis. Therefore we now have a configuration switch in LocalSettings.php ("$respectParserCache"). By default this is set back to the older policy of 'true dynamic behaviour'. See the parameter allowcachedresults.

first version of dplcache

DPL now contains a cache mechanism which can store DPL results for an arbitrary time. The cache will even survive edit actions of the page containing the DPL statement as long as the DPL statement itself is not changed. This is meant for large wikis (Wikipedia) where a DPL query might be expensive to run. Currently the cache uses the filesystem (images directory with hashed subdirs); this may change to using the database later.

new command dplcacheperiod

allows you to set the duration period of the dplcache (in seconds)

date/time preferences

all dates are now OUTPUT according to the user preferences / time zone. Notet that for the moment the selection criteria is still based on UTC time.

Version 1.8.1

bugfix %DATE% 

when using addeditdate=true and ordermethod=lastedit and adduser=false the built-in variable %DATE% was not expanded

bufix at 'allrevisions...'

allrevisionssince delivered wrong reults; this should be fixed now.

Version 1.8.0

A lot of work has gone into this release of DPL. The main goal is to provide downward compatibility with an ancient version of DynamicPageList which is being used on some WikiMedia sites. (sometimes called "Extension:Intersection", sometimes also "DynamicPageList").

The idea behind is to re-unite all the different versions and to replace all of them by release 1.8.1 (or later) of DPL. This takes into account that 1.8.0. may contain some minor incompatibilities which will be fixed by DPL 1.8.1++.

Apart from the downward compatibility issue DPL 1.8.0 brings a couple of new features which may be useful, too.

new commands stablepages and qualitypages

these commands allow to control output regarding certain page flags which can be set via an extension called FlaggedRevisions.

new debug level

debug=6 allows to see the DPL statement which would be used by DPL without actually executing it.

flexible URL parameters

DPL can now take up to five parameters from the URL (DPL_arg1 .. DPL_arg5); this can be useful in advanced template design

result scrolling is much easier now

DPL uses two URL parameters (DPL_offset and DPL_count) for result scrolling -- see DPL Example 020.

new built-in variable %DPLTIME%

can be used for performance measurement - shows the net time spent within the DPL extension (which comprises database access and result processing)

new command execandexit

DPL performs a command but does not execute a query. This is used to convert URL parameters into user variables which can then be used outside the DPL code, e.g. in an #if or #ifexpr statement.

numeric namespace specification

for downward compatibility reasons DPL now accepts also numbers as namespace identifiers. It is not recommended to use that feature.

code restructuring: There has been a major restructuring of the source code to improve readability and maintainability. You should have in mind that such modifications can create unwanted side effects. Should you observe unexpected effects or even minor deviations from the behaviour of older DPL releases, please open an ISSUE.

Version 1.7.9

automatic link to Template:Extension DPL

Every page containing a DPL statement will automatically create a link to Template:Extension DPL. You should create this Template in your wiki. We suggest that you copy the source code from our version. The idea is that via this connection you can easily find out which pages in a wiki contain DPL calls. This may help in maintaining them and it will probably be needed by the dplcache feature which is under construction.

new experimental feature

dplcache - undocumented at the moment until it has been thoroughly tested

bugfix in errorhandling

parameter substitution within error message did not work. "%DPL-messages" should now be more clear to the user

bugfix in localisation

i18n file was corrupted and has been replaced by a new version. Please check the Chinese and other versions;

bugfix in ordermethod=lastedit, firstedit

this led to the effect that too few pages/revisions were shown

bugfix at include=* 

a php warning could arise (Call-time pass-by-reference has been deprecated .. line 3882); this should be gone now

new built-in variable

 %IMAGE% - contains physical image path

new built-in variable

 %PAGEID% - contains internal page_id number

new DPL command line argument

DPL_offset: this can be used to improve page scrolling - see DPL Example 013

Version 1.7.8

template inclusion accepts wiki comments

when including parameters of template calls DPL now silently ignores optional wiki comments which may be placed between the parameter name and the equals sign. See Issue:Html-comments_in_parameter_names

include=* now also works with table

Previous versions of DPL could not place the whole content of a page into a table field of the result report. Now you can do this and you can apply tablerow formatting as well.

bugfix

 %PAGES% was wrong (showing the total number of pages in some cases)

bugfix

there was a severe bug concerning the inclusion of labeled sections. In fact, it looked as if labeled sections were not included at all (the text was erroneously truncated to 0 before it was shown).

new feature

minrevisions & maxrevisions -- this allows to specify a threshold for the number of revisions of a page which must be present for the page to be shown in the DPL result set.

Version 1.7.7

new option to protect DPL agains mis-use

a configuration option which can be set in the LocalSettings.php allows to configure DPL in a way that DPL queries will only be run from PROTECTED PAGES. See DPL security.

Version 1.7.6

bug fix at includematch

there was a php error which occured when trying to match content of a non existing chapter (missing array element at line 3887). This is now fixed.

Version 1.7.5

new command suppresserrors

setting this to 'yes' or 'true' will prevent a warning from being shown if your DPL statement has an empty result list.

minor internal chang in generated SQL

we now use LOWER instead of UPPER for comparisons which shall ignore case

new command updaterules

this allows to change articles (' batch editing ') which are selected by a DPL statement

includematch now also works with include=*

note that includematch always tries to match the raw text, including template parameters

allowcachedresults now accepts the option value 'yes+warn'

new command usedby

new built-in variable %CATBULLETS%

Version 1.7.4

new command imagecontainer

produces a list of all images which are contained in an article. Non existing images can be included or excluded, see Test imagecontainer

Version 1.7.3

preliminary bugfix for MediaWiki 1.12 (thanks to Rezyk!)

Due to the changed parser there were servere problems with certain DPL queries. Hopefully the majority of these problems will no longer exist with Version 1.7.3. Please check and report any starnge effects you may observe!

The %SECTION% variable now can be used within multisecseparators

This makes it possible to write a simple DPL query which creates a table where you see all the headlines used in a group of articles. If you have a group of articles which belong to a common category and which should (more or less) have the same chapter structure, this is an ideal way to monitor similarities and differences. See the Example.

Version 1.7.2

improved sorting of tables

via tablesortcol you can specify a column which will be used for an initial sort when the table is first displayed. See Test table, example (B).

Version 1.7.1

minor new feature at include

when including a template the colon-separated parameter name list can now contain %variables%. Thus the link to the article where a table row comes from need no longer be in the first column; see Test table for an example

Version 1.7.0

new command imageused

allows to select pages that use a certain image

minor bugfix

spaces were not correctly treated in articlecategory

minor bugfix

installation checking could cause problems depending on php version

Version 1.6.9

new command includetrim

removes leading and trailing whitespace form transcluded contents.

respecting 'nonIncludableNamespaces'

DPL is no aware of protected namespaces; a query will not show output from articles in such namespaces.

Version 1.6.8

new operator & in category command

this is only a syntax variant. Instead of specifying multiple 'category' lines you can use a '&' for the AND condition.

Version 1.6.7

bug fix

Release 1.6.6 had a negative side effect on 'goal=categories'. This has been fixed with 1.6.7.

Version 1.6.6

new variable

%TOTALPAGES% returns the correct number of pages found regardless of count limits.

minor security fix

single apostrophs were not escaped in a very rare situation

Version 1.6.5

new function

includematchparsed applies regular expressions to the pre-parsed contents of template parameters. This may be useful if the parameters of your templates contain varaible references or other template calls.

two minor technical bugfixes

passing parameters by reference, missing array key

%VERSION%

this pseudo variable contains the current version of DPL; it can be used within resultsheaders and footers.

Version 1.6.4

Bugfix

Syntax error with static variables in connection with option reset.

Matrix view

new parser function '#dplmatrix:' introduced, see dplmatrix.

Version 1.6.3

Labeled section inclusion

If the pattern starts with a "*" it will be taken as a regexp; "**" stands for "any section". In both cases the tag name will be prepended to the contents (separated by "::"). See include.

Version 1.6.2

Bugfix - The pattern match for template names in include was not precise enough

You could involuntarily grasp additional templates the name of which started with the same name followed by a space and some other characters.

Version 1.6.1

Callbacks obviously need a global adresse in some older versions of MediaWiki

Now there is a small indirection for this in the code which can be eliminated some time in future.

Escaping of '/'

A slash in a page name (e.g. if you use subpages) could lead to php errors because the the '/' is internally used as a preg_delimiter. Now slashes are being escaped.

Version 1.6.0

This a purely technical release

You should observe no differences between 1.5.3 and 1.6.0. There is one exception: If you had set one of the global DPL configuration switches (like $wgDPL2XxxYyy) in your LocalSettings.php you must now change it to ExtDynamicPageList2::$xxxYyy.

Version 1.5.3

eliminated false warning

when using title= together with include=* there was a false warning about empty result set

new parser function #dplchapter

you can extract a chapter from a text in the same way DPL extracts chapters from articles in the include statement.

added articlecategory

talk pages can be selected based on the category of their base page

include text truncation

now is aware of pre & nowiki tags

phantom templates

now support additional variables: %DATE% and %USER%

added randomseed

Version 1.5.2

enhancement of include

now you can delimit the length of selected template parameters

bugfix at include

delimiting a transcluded chapter did not work correctly with a limit of 1

offset and count are now directly implemented in SQL

If you had, say, 1000 entries in your result set and the pre-configured SQL limit of DPL was 500 you could never show entries 501..1000. Now this is possible (using an offset of 500 in our example).

Version 1.5.1

bugfix at addcontributions

table name prefix led to invalid SQL statement

bugfix at resultsheader

if includematch reduced a set of matching articles to zero, this was not recognized by the noresultsheader

Version 1.5.0

changed the algorithm in the Call extension

the older version was fooled by browsers inserting cookie variables at the beginning of the parameter list. This should be gone now. Use "DebuG" as a pseudo target for testing.

Version 1.4.9

improved error handling

invalid command names did not always lead to a warning; comands without '=' were silently ignored. A command starting with an '=' lead to a runtime error. All this has been fixed. It is recommended to upgrade to this version of DPL as the improved error detection will help you to avoid mistakes.

Version 1.4.8

improved Call extension

Some users had problems (often depending on the browser and the way it handles cookies). This should be solved now. In addition you can call Special:Call/DebuG to get an internal trace.

minor changes at Wgraph

see the change log of Wgraph.

there were no changes of DPL in this release .

Version 1.4.7

new feature

skipthispage can be set to 'no'. This will include the page containing the DPL query into the result set (if the query conditions match). Normally this page is excluded from the result set. Allowing to include the page may cause trouble if your DPL query transcludes contents from nested templates.

Version 1.4.6

new feature

addcontribution allows to check who contributed how much. Only works for articles which were edited recently. See Test addcontribution.

Version 1.4.5

error in "Call extension" corrected

There have been two errors in the Call extension which may have caused trouble to some users, either in combination with MediWiki 1.11 or with some (popular) browsers (e.g. Firefox, Opera). It is recommended to download 1.4.5 even if you yourself did not notice the problem as it may have affected some of the users of your website.

Version 1.4.4

corrected handling of numeric template parameters

See Issue:Include positional template parameter

Version 1.4.3

new feature

include=##regexp, i.e. you can now use a regular expression to find a chapter title. See include.

Version 1.4.2

bug fixes

1. sometimes a SQL error in the 'group by' clause could occur. Only installations which used a MySQL table name prefix (like mw_ e.g.) were affected
2. when using ordermethod 'sortkey' an SQL error occured. This has been fixed. 'sortkey' now automatically implies 'category' (which is necessary from a logical point of view).
3. in some installations, the use of addpagecounter, addpagesize or add...date caused an SQL error. This should no longer happen.

new parameters

1. tablerow: This makes it possible to format items of a table individually. One can add layout attributes, convert template parameters to interwiki calls, highlight certain values, etc. The new tablerow works closely together with table and include. See the manual for details.
2. eliminate: this parameter can be used as an alternative for reset, but behaves slightly different. It requires some extra processing so it should be used with care.
3. ignorecase: this will make comparisons case insensitive. It has an effect on (not)linksto, (not)uses, (not)titlematch, (not)titleregexp, title.

multiple template parameters in include

Now an include statement can return multiple parameter values of a template invocation; this is very useful for table output (one parameter per column). It removes the necessity to write standard 'phantom templates' which only return their parameter values.

design change in 'reset'

reset is no longer used in a separate DPL statement. Instead reset becomes a normal parameter of a DPL query. There are some more subtle changes in behaviour of reset. Read the manual.

new debug option

debug=5 will show the wiki text which is produced by your DPL query. This can be very useful when creating complicated output or when you are stuck with missing newline characters, etc.

Version 1.4.1

bugfix regarding the debug command

debug=3 did not work correctly (lead to an empty page most times)

exception handling improved

Now DPL complains if there is a SQL error. Before it could happen that you only got an empty page.

bugfix regarding distinct=strict

This did not work correctly in some rare constellations

Version 1.4.0

added a new option for distinct

the value 'strict' can be used to reduce the amount of output you get from a linksfrom or linksto statement. See Test distinct.

Version 1.3.9

additional sortkey

now you can use 'pagesel' as a parameter for ordermethod. This will order (group) pages by the pagenames used as a selection in the linksto or linksfrom command.

added noresultsfooter and oneresultfooter

guess what they do?

new command table

This makes it a lot easier to present DPL output in wiki table format. See the manual and the examples.

Version 1.3.8

Bugfix

Extracting a template parameter could be mislead by pipe characters sitting inside hyperlinks. This has been fixed. It only affected the {Template:xyz}:parameter_name syntax variant.

Version 1.3.7

Bugfix

In release 1.3.6 using "ordermethod=sortkey" caused an SQL syntax error. Please upgrade to 1.3.7

extended boolean support

parameters of type boolean now accept true, false, yes, no, 1, 0, off, on as values.

Version 1.3.6

The DPL special page was removed

The DPL GUI is a better suited alternative. There were some minor features in the DPL special page which are not available in the current revision of the GUI. If somebody feels that these features should be made available again, I would recommend to create a subpage of the current GUI and add a button to the GUI which gives access to that subpage (containing the extended functions). I would not like to overburden the standard layout of the DPL GUI with a dozen of more or less exotic options... The source code of the old special page is still available in the version history of the ZIP archive.

allow individual collations for sorting

a new option called ordercollation makes it possible to define special collating orders which e.g. allow case insensitive sorting. Use with care: You must specify a collation symbolic name which is known to MySql - otherwise you will get a SQL error (use 'debug=4' to check!). A good guess is latin1_swedish_ci.

path to standard collating sequence regarding the symbols which represent card suits

As I use DPL heavily in a wiki which deals with the game of Bridge I wanted to have the suit symbols ordered in the canonical way. This should not do harm to anybody but may encourage the use of DPL in Bridge playing communities.

bugfix re. %PAGES%

 %PAGES% did not work when used with mode=category. Now it does.

On special request of the people from the wonderful city of Vienna there is a new feature regarding subpages

Please make sure that %PAGES%, column output and other related features still work as expected when used together with 'includesubpages=no'.

Version 1.3.5

bug fixed at ordermethod

Previous versions had trouble with ordermethod=category,sortkey

Version 1.3.4

changed layout for multi column output

Now the columns size is calculated in a way which creates columns of equal length excpet the last column.

SQL errors eliminated

There were some rare cases where you could run into a SQL error complaining about ambuguities in column names - esp. when using 'linksfrom'. Hopefully all of these problems have no gone.

subcategory expansion corrected

spaces in category names prevented DPL from descending into subcategories.

Version 1.3.3

Bugfix at ordermethod parameter checking

if more than one parameter was used, there could be false complaints about invalid parameters.

Version 1.3.2

Warning at missing selection criteria

The warning caused by missing selection criteria will now only be issued if no DEBUG level was set

%NAMESPACE% added

This variable contains the namespace of the current page in teh DPL result set

%PAGESEL% added

This variable contains the page which was used as a starting point in a 'linksfrom' or 'linksto' condition. Note that these parameters accept a list of pages.

Headingmode with columns

'headingmode' now works with multiple columns; we assume that the vertical space needed for a heading roughly equals two normal lines

Bugfix with error messages

parameter syntax errors were not shown in some cases

New Parameter 'reset'

issuing a separate DPL statement which contains 'reset' as the only parameter allows to get rid of unwanted references of a DPL page to templates, images, categories and other pages; read the manual.

Bugfix with SQL error

ambiguous 'page_name' in SQL statement fixed (appeared when namespace= and linksfrom= were used together)

Modification of 'includematch'

includematch now always uses php preg_match instead of ereg - therefore patterns must have delimiters! Before #patterns had been matched using ereg

added 'oneresultheader'

this header is used if there is exactly one entry in the result set. For the friends of correct grammar ..

allow nesting of DPL statements

The symbols ²{...}² can be used to depict a template call which shall be executed while DPL is walking through its result list. This is a major step forward in combining DPL with other extensions. Read the Manual!

Version 1.3.1

minor modification at resultsheader and resultsfooter

these statements do no longer emit an implicit newline into the DPL output stream. But you can add \n if needed. If you observe unexpected fromatting with resultsheader or -footer, try adding a \n before and after your resultsheader. See also Test resultsheader. The benfit of the changed behaviour is that you can create inline text which contains just the sum of pages (%PAGES%) of a DPL query. See Test resultsheader.

Version 1.3.0

all boolean parameters now accept 'yes' and 'no' as an alternative for 'true' and 'false'.

Version 1.2.9

resultsfooter added

in analogy to resultsheader

resultsheader and resultsfooter understand '\n'

The charcters '\n' are replaced by a newline within the resultsheader and resultsfooter. This is useful if you want to output wikitext which needs to start at the beginning of a new line.

parameter parsing at 'include' improved

if you specify 'include={template}:nameOrNumber' you will now get the correct parameter value even if the parameter itself contains another template call. This was not the case in earlier versions.

Version 1.2.8

syntax variant

many DPL querys contain the sequence 'mode=userformat' and 'listseparators=...' now there is a short notation for this. We allow 'format' as an alias for 'listseparators'. And if 'format' or 'listseparators' is specified, 'mode=userformat' will automatically be assumed

internal

empty parameters are silently ignored

SPECIALPAGE

The special page in its current form will not survive. There is a better replacement which allows you to write your personal GUI for DPL queries. Thanks to Nad for his 'SimpleForms' extension this is now possible. See DPL:Catlist.

Version 1.2.7

bugfix with %PAGES%

there was a problem with %PAGES% and multicolumn output

bugfix with undefined php variable

error occured when using a "*" in the 'category' parameter (i.e. using the subcategory matching feature)

Version 1.2.6

added 'distinct' option

normally 'distinct' is 'true'; there are some rare cases - esp. in combination with %PAGESEL% where you mioght want to set distinct=false

added '%PAGESEL%' variable

in combination with 'linksto' and 'linksfrom' this new variable will give you the name of the page which was used as an input to the selection. This is useful if your DPL query uses a list of pages as starting point for 'linksfrom' or as target point of 'linksto'.

'linksfrom' and 'linksto' do no longer complain about empty parameters

instead these are silently ignored

changed SQL query basics to allow duplicate use of page table

this is an internal change which was necessary because of the enhanced functionality of linksfrom/linksto

Version 1.2.5

added includenotmatch

this allows to specify a regexp (based on transcluded contents) which must NOT match the contents

Version 1.2.4

error corrected

ordermethod "sortkey" did not work because of missing break in case statement

error corrected

counting of selected articles was wrong in older versions (see Test includematch)

Version 1.2.3

allow %0 in include statement

 %0 can now be used to transclude the text before the first chapter.

Version 1.2.2

allow simultaneous conditions on revisions

up to now only one selection criterion regarding revisions could be applied within a query (the others were silently ignored). Now you can use more than one condition within one statement. This allows to retrieve article revisions which belong to a certain time range.

added %CATNAMES%

A new pseudo variable was added which contains the categories of a page in natural text, separated by comma. The difference to %CATLIST% is that %CATLIST% contains a list of links to the categories.

parameter "noeditbox" added to DPL special page

adding "&&noeditbox" to the call of the special page will suppress the form containing the query, so that the user will just see the result.

Version 1.2.1

SQL string escaping corrected

there were some cases in which a page name containing a single ' could cause harm to SQL syntax (resulting in syntax errors). This was corrected.

titlemaxlength now also works with mode=userformat

before titlemaxlength only had worked in the other modes.

Version 1.2.0

minor change in SQL syntax

replaced " by ' to increase compatibility with Postgres etc.

Version 1.1.9

added ordermethod=titlewithoutnamespace

this is especially useful in combination with mode=category; it ignores the namespace when sorting articles by name. As it also makes the SQL statement considerably less complex you should use this option if your result contains articles from only one namespace or if the namespace does not matter.

the special page for DPL now accepts command line parameters

using two consecutive "&" acts like a newline in a DPL statement

Version 1.1.8

added two new options

to include the author or the lasteditor of a page

new concept of "goals"

whereas DPL normally will produce a list of pages (as the name indicates) it is now also possible to produce as a result the list of categories to which the selected pages belong. For example: show all categories which have members that were edited by userX since last Monday..

Version 1.1.7

bug fix concering AllMessages

There was a warning (caused by DPL) showing up at Special:AllMessages. The warning is gone now.

bug fix with DPL extension path

Due to a hardcoded directory path you could run into an error with the new special page. This should now be resolved.

Version 1.1.6

small bug fix at template inclusion

There was a php error if you tried to use the same template for DPL as was used in the original article. Normally you would add some suffix to the template name (in which case the error does not happen).

Version 1.1.5

made caching configurable

new parameter 'allowcachedresults='

Version 1.1.4

first version of DPL SPECIAL PAGE

still in its infant state ...

short syntax for selecting a single template parameter

include={template}:3 will select the third chapter

support # as a comment symbol within DPL commands

lines starting with a # will be ignored

allow more flexible date specification

(2007-03-10 instead of 20070310)

Version 1.1.3

bugfix for 1.1.2

If you get a php warning about "parameter passing by reference" you should download this release.

Version 1.1.2

sections which shall be included can now also be identified by number

include= understands %1, %2 etc and %-1 for the last section of an article (there is no %-2). %SECTION% will show the headline of the chapter.

Version 1.1.1

There is experimental support for category hierarchies

category=*country will find pages which belong to "country" or to a direct subcategory of country. NO, there is no way to go deeper than just one level at the moment. The wiki database design is not very well suited for this type of tree expansion ...

starting with 1.1.1 there are some additional files in the source code

they might become the nucleus of a "DPL special page". There is no need for another "require_once" in your LocalSettings. Just ignore these files for the moment.

The ZIP archive is the only supported source code download mechanism

You should not try to extract the source code from the wiki text under "Source". Unfortunately there were some problems with the upload mechanism so that in all versions between 1.0.1 and 1.1.1 character sequences like "%CA" (which happen to appear in the source code) were erroneously transformed into double byte characters during upload. If in your installation %DATE% or %CATLIST" do not work this may be the reason. In that case you should download the latest ZIP archive with the sources.

Version 1.1.0

parser cache disabling changed

if 'title=' is set, the parser cache will not be disabled. There should be no difference in all other cases.

Version 1.0.9

new parameter 'openreferences'

allows to list non-existing pages via the 'linksfrom' command.

Version 1.0.8

new parameter 'notlinksfrom'

solved a bug which had to do with invalid arguments at linksto, linksfrom etc

includematch changed

now the regexp checks against the calling code, not against the output of the DPL template

bugfix at 'replaceintitle'

Version 1.0.7

some improvements of includematch

regarding multiple occurencies of the same template or chapter; now only those occurencies are taken which match the condition.

Version 1.0.6

now there is an experimental feature which allows to make selections based on included contents (includematch=)

you can define a regular expression which must match the included contents (in case of template based matching it must match the output of your template). Maybe this feature will be changed in near future based on experiences of users ...

Version 1.0.5

now there is a set of powerful parameters which allow page selection to be based on the user who edited a page

createdby, notcreatedby, modifiedby, notmodifiedby, lastmodifiedby, notlastmodifiedby; see Test createdby and the manual.

Version 1.0.4

new parameter linksfrom added

DPL can now also output all links which start from one or more given pages. This makes sense if you have pages which contain many links and you want to extract a subset of the pages which are referenced.

Version 1.0.3

syntax modifications in REGEXP matching

when matching categories and titles we use the whole argument as one regexp expression, i.e. the pipe character retains its normal meaning.

minor corrections in title=

there was a problem with articles names containing spaces

Version 1.0.2

category matching supports LIKE and REGEXP

title matching supports REGEXP

Version 1.0.1

new parameter "title" added

this parameter selects exactly one page and implicitly sets mode=userformat; this may sound somewhat strange but is useful if you want to use DPL´s capabilities for content transclusion only. See the manual for an example.

"include" now works as an alias for "includepage"

Version 1.0.0

support for revisions added

you can now restrict your search to articles which had a revision before or after some point in time; you can also show all revisions before or after some point in time

dominantsection added

this feature aims at generating sortable lists which contain included parts of other documents; if a document calls the same template many times (or contains many chapters with the same heading) the definition of a dominant section will lead to separate output rows for each such call or chapter.

replaceintitle added

you can change the contents of %TITLE% via replacing part of it by some other string

Version 0.9.9

default template added

if you use template based inclusion and you have articles which do not include the original template, a template with the extension ".default" (appended to the dpl substitute for the original template) will be called.

rowcolformat added

when you use columns= or rows= in the output you can now control the cellspacing, cellpadding and backgroundcolor of the output grid.

the multisecseparator tags now also understand variables like %PAGE%

This is helpful when generating sorted lists

Version 0.9.8

inclusion of labeled sections

another bugfix; when including labeled sections using the usertag syntax, DPL only worked correctly for the first inclusion of a given page. If you had more than one inclusion from the same page every inclusion after the first was reduced to a link (due to a too defensive algorithm for breaking recursions). This has been solved. See Test section inclusion.

TOC behaviour changed

You may have observed that mediawiki often creates a table of contents (TOC) for the output of a DPL statement. It also generates editable sections in certain cases. This behaviour is based in the mediawiki engine but often not very desired in our context. You you can use NOTOC and NOEDITSECTION pragmas to stop this behaviour (typically in a resultsheader statement, see Example 2). For mode=category a TOC and editable sections do not make any sense. So DPL inserts the two pragmas now automatically. Note that as a consequence you must manually put a TOC pragma into the article which contains the DPL query if you want to see a TOC for your article.

additional parameters for template based inclusion

now there are two additional parameters named %PAGE% and %TITLE% which are passed to every template when we perfrom a template based inclusion. Thus the template can produce a link to the source file from where it was include (note that the PAGENAME macro cannot be used for this purpose as it contains the name of the page which contains the DPL statement).

linksto, uses, titlematch and their not-equivalents now understand a set of arguments which form an OR-group

the alternatives are separated by a pipe symbol; the "not variants" are interpreted in a way that the "not" is applied to the whole OR expression. So, notlinksto=London|Paris means that an article must not link to (London or to Paris) to be selected. You could also say that it must not link to London AND it must not link to Paris.

in some rare cases it could happen that a template text was included although the template wasn´t called in the original source

This error has been fixed with patch1 of 0.9.8.

Version 0.9.7

bug fixed with transclusion of labeled sections

Due to an error in all versions below 0.9.7 the transclusion of labeled sections only worked if you had LabeledSectionTransclusion installed as another mediawiki extension (besides DPL). This should be solved now.

addfirstcatgeorydate can be used with more than one category selection

A restriction on input parameter combinations was released. If an article belongs to more than one category there is no defined procedure which date will be shown.

Version 0.9.6

space sensitivity in template recognition eliminated

There was a bug which prevented DPL from recognizing template calls in an included article when there were spaces or linefeeds between the opening double braces and the template name. There was also another bug which led to misinterpretations when you had two templates where one of them had the name of the pther plus some appended letters. Both errors have been corrected with Version 0.9.6; see Example 1 and Nigunda Test.

changed semantics of secseparators

To gain more flexibility it was necessary to modify the semantics of the secseparators statement. Please check the DPL statements using this parameter and adapt them if necessary. For details see the manual.

allowed multiple inclusion of the same template or same chapter

If a document includes the same template many times you will get all hits now. You can separate them with the new parameter "multisecseparators="

heading based inclusion

a single # will include the text before the first heading

recursion blocking

The page containing your DPL statement will never show up in the result. You need no longer exclude that page explicitly.

userdateformat

Now you can define the way you want to see a DATE; use the syntax of php gmdate(), i.e. "Y-m-d (D)" would give "2007-02-26 (Mon)" etc.

To show only the time you could use "h:i".

php warning eliminated

IN php5 (with a certain config parameter setting) there was a warning about calltime reference passing of parameters. This should now be gone.

new Variable %TITLE%

This new variable contains the page name without the namespace; it can be used to create a link together with %PAGE% like this:

[[%PAGE%|%TITLE%]]

sophisticated character escapings

We use the following replacements within DPL parameter interpretation:

•  » is translated to >
• « is translated to <
• ¦ is translated to |

This makes it possible to include tags (even other mediawiki extensions!) within a DPL call

Version 0.9.5

introduced "offset="

With this new option you can (in combination with "count=") restrict the output to a range of hits

Version 0.9.4

allowed "-" with "categories="

With this new option you can exclude categories from appearing in the headings when grouping output bay categories

disabled UTF8 conversion with sortkeys

... as it led to SQL arrors (incompatible collations...) with non-UTF8 MysQL database settings

option headingcount= added

Now you can decide whether to show or to suppress (=default) the text line with the number of entries in a heading group

Version 0.9.3

allow ¦ as an alias for |

This makes syntax looking better when using DPL in parser function mode

escapelinks= introduced

Regarding images and categories you can now decide whether yo want links in the output result (this is default) or you want the categories added to your apge and/or the images displayed directly

Version 0.9.2

problem with headlines in headingmode corrected

addcategories

bug fixed

new variable %CATLIST%

in mode=userformat you have access to the list of categories via this built-in variable

Version 0.9.1

adduser

problem with adduser solved

Version 0.9

There are many enhancements compared to older versions, such as

• usability as parser function
• this had some influence on downward compatibility with older versions, especially regarding parameter interpretation
• enhanced page inclusion
• titlematch, nottitlematch
• notlinksto
• resultsheaders
• mode=userformat / listseparators= / many new %variables%
• categoriesminmax
• uses= (template based inclusion)
• randomcount
• columns and rows in the output
• includemaxlength
• ... and some others

Version 0.8.x

The extension was called DPL2 until version 0.8.x; for details of that part of the history see meta wiki description of DPL2
