Constructing arrays

complexarraydefine

This function creates a new array, identified by 'key'.

Syntax

{{#complexarraydefine:key|array|delimiter|noparse}}

Erklärung

  • key (required) – The name of the array;
  • array (required) – The array as WSON, or using a delimiter.
  • delimiter (optional, default: ,) – The delimiter used when defining a simple array.
  • noparse (optional) – Arguments to tell the parser what to parse in the 'array' (see #Manipulation of the parser).

Beispiele

Define a multidimensional array called 'baz' 
{{#cadefine:baz|(("foo":(("bar":"baz"))))}}
Define a simple array called 'bex' (note, sometimes WSArrays does not properly recognise delimiter-separated arrays; try adding a delimiter instead of using the default (,)) 
{{#cadefine:bex|foo; bar; baz|;}}

complexarraydefinedarrays

This debug function creates a new array containing the keys of all currently defined arrays.

Syntax

{{#complexarraydefinedarrays: key}}

Erklärung

  • key (required) – The name of the array that will contain the keys of the currently defined arrays


Working with arrays

Extraction

complexarrayprint

This function prints the values of the array in a custom format.

Syntax
{{#complexarrayprint:key|options|noparse}}

Erklärung
  • key (required) – The name of the (sub)array that should be printed;
  • options (optional):
    • markup – Print the result as WSON.
  • noparse (optional) – Set to "true" to tell the parser not treat the output as wiki syntax.


Beispiele

We have an array called 'foobar':

  • 0
    • foo: bar
    • baz: quz
  • 1
    • foo: quz
    • baz: bar
  • 2
    • baz: bar
    • foo: bar
  • 3
    • baz: {{SomeTemplate|Test}}. ?UNIQ347fb3f0c7f3d9c-5
If you defined the array with noparse, the behavior is different.
Function Result 
{{#caprint: foobar}}
  • 0
    • foo: bar
    • baz: quz
  • 1
    • foo: quz
    • baz: bar
  • 2
    • baz: bar
    • foo: bar
  • 3
    • baz: Test. {{SomeTemplate|Test}}
{{#caprint: foobar[0]}}
  • foo: bar
  • baz: quz
{{#caprint: foobar[3]}}
  • Test. {{SomeTemplate|Test}}
{{#caprint: foobar[0][foo]}}
 bar

complexarraysize

This parser function returns the size of a (sub)array.

Syntax
{{#complexarraysize:key|options}}
Explanation
  • key (required) – The name of the (sub)array;
  • options (optional):
    • top – Only count the number of items in the top array (not recursively).


Beispiele

We have an array called 'foobar':

  • 0
    • foo: bar
    • baz: quz
  • 1
    • foo: quz
    • baz: bar
  • 2
    • baz: bar
    • foo: bar
Function Result 
{{#casize: foobar}}
 9 
{{#casize: foobar[1]}}
 2 
{{#casize: foobar|top}}
 3

complexarrayslice

This parser function can extract a slice from an array.

Syntax
{{#complexarrayslice:new_key|key|offset|length}}
Explanation
  • new_key (required) – The name of the array that is going to be created;
  • key (required) – The name of the array that needs to be sliced;
  • offset (required) – For a positive offset, the new array will start at that offset in the first array. For a negative offset, the new array will start that far from the end of the first array;
  • length (optional) – The length of the new array.


Beispiele

We have an array called foobar:

  • 0
    • foo: bar
    • baz: quz

This gives the third element of the array.

boofar:

  • 0
    • boo: bar
    • far: quz
{{#caslice: boofar | foobar | -1 }}

This gives the last element of the array:

boofar:

  • 0
    • foo: quux
    • bar: bar

Anonymous

These functions use anonymous arrays. The function handles both the definition and output of the array. You do not have to define an array beforehand.

complexarrayarraymap

This parser function is very similar to #complexarraymap, but the input and output is handled in the same function (which makes it anonymous).

Syntax
{{#complexarrayarraymap: value | delimiter | variable | formula | new_delimiter }}
Explanation
  • value (required) – The value to be split;
  • delimiter (required) – The delimiter to split value on;
  • variable (required) – String to be replaced in 'formula';
  • formula (required) – String where 'variable' is replaced;
  • new_delimiter (required) – The delimiter between results.


Examples
Function Result 
{{#caamap: a, b, c | , | @@ | Current variable: @@ | !<br/>}}
 
Current variable: a!<br/>
Current variable: b!<br/>
Current variable: c

{{#caamap: a; b; c | ; | ! | Just ! test | <br/>}}
 
Just a test<br/>
Just b test<br/>
Just c test

complexarrayparent

This function returns the key of the parent of the given key.

Syntax
{{#complexarrayparent: key }}
Explanation
  • key (required) – The key from which the parent key should be returned


Examples
Function Result 
{{#caparent: foobar[0][1][test] }}
 
foobar[0][1]


Wairudokado operator

The Wairudokado operator (Japanese: ワイルドカード, pronounced Wairudokādo, meaning wildcard; a tribute to the Scope Resolution Operator in PHP) is a powerful operator that gives users the ability to use wildcards when manipulating or printing subarrays.


Example

This operator can be used on every parser function that supports subarrays (such as #complexarrayprint).

Suppose we have the array foobar:

  • 0
    • name: Foo
  • 1
    • name: Bar
  • 2
    • name: Baz
  • 3
    • name: Bex

And we want to print every value of "name". We could use a #complexarraymap to iterate over the array and print each value seperately, but we can also use a Wairudokado operator in the #complexarrayprint function.

Function Result 
{{#caprint: foobar[*][name]}}
  • Foo
  • Bar
  • Baz
  • Bex
When a Wairudokado operator is at the end of the pointer, it is ignored. Sequential Wairudokado operators are interpreted as one.


Semantic MediaWiki

This result printer requires Semantic MediaWiki 3.0 or higher.

This extension introduces a new format for displaying Semantic MediaWiki results. In order to use the new format, use format=complexarray. Because the result printer defines a new complexarray, you need to provide a name for that array using name=<name>; if name is left empty, the result printer will print the array as WSON.

Semantic variables

A list of semantic variables is included in the complexarray when you query a list of pages. The following variables are included:

catitle
The title of the page
cafullurl
The full URL of the page
canamespace
The namespace the page lives in
caexists
Whether or not the page exists (0/1)
cadisplaytitle
The displaytitle of the page

Additional parameters

WSArrays defines two new parameters:

name
The name of the array that is going to be created
simple
Option to hide Semantic variables from page results as well as hiding mailto: prefixes on email results (yes/no, default: yes)

Seeing tables instead of complex arrays

In case Semantic MediaWiki renders a table when format is complexarray, you must first check if you have set $wfEnableResultPrinter to true.

If this is the case and it still does not work, WSArrays might not have been able to create a symbolic link from the SemanticMediaWiki folder to the WSArrays folder. This link can be manually created by copying the file ComplexArrayPrinter.php from the extension's root folder to SemanticMediaWiki/src/Query/ResultPrinters.

Writing extensions

While WSArrays provides many functions for manipulating and showing arrays, sometimes these are not enough.

For this reason, we provide an interface to easily extend the functionality of WSArrays with new parser functions.

Extensions are placed in the extensions/ directory. Each extension is implemented as a derived class from Extension.php. The name of the file in which this class will be located, must be the same as the class name (case-sensitive). An example for the class ExampleClass would be ExampleClass.php. The class must implement at least the following methods: 

<?php

class ExampleClass extends Extension {
    /**
     * Returns the name of this parser function.
     *
     * @return string
     */
    public function getName() {
        return 'exampleclass';
    }

    /**
     * Should return an array containing aliases of this parser function.
     *
     * @return array
     */
    public function getAliases() {
        return [
            'caexample',
            'caexampleclass'
        ];
    }

    /** 
     * Should return either 'sfh' or 'normal'. 
     * When 'sfh' is returned, the setFunctionHook function is called with Parser::SFH_OBJECT_ARGS
     * as a parameter, allowing for a deeper integration with the parser.
     *
     * @return string
     */
    public function getType() {
        return 'sfh';
    }

    /**
     * This function is called by the parser.
     *
     * @return mixed
     */
    public static function getResult( Parser $parser, $arg1, $arg2, ...) {
        return 'Foobar';
    }
}

?>

Returning the result

getResult() is executed by the parser hook.

You can read how to write parser functions here. The documentation below is specific to WSArrays.

Manipulating arrays

All arrays in WSArrays must be stored as a ComplexArray object.

If you want to manipulate an existing array, you must convert the ComplexArray object to an array, manipulate the array and then convert it back to a ComplexArray object. 

public static function getResult( Parser $parser, $arg1, $arg2, $arg3 ) {
    // $arg1 contains the name of an existing array;
    // getArray() will return the array.
    $array = WSArrays::$arrays[$arg1]->getArray();

    // Manipulate array...

    // Arrays are stored in the variable $arrays, located in the WSArrays class.
    // If you do not save the array as a ComplexArray, existing parser functions will not work with this array.
    WSArrays::$arrays[$arg1] = new ComplexArray( $array );

    return null;
}

or when using SFH_OBJECT_ARGS: 

public static function getResult( Parser $parser, $frame, $args ) {
    // Convert the first element in the $args array into a string.
    // Omit PPFrame::NO_ARGS | PPFrame::NO_TEMPLATES if you need the parser to first parse the arguments.
    // You can also use GlobalFunctions::getSFHValue() and GlobalFunctions::rawValue().
    if ( isset( $args[0] ) ) {
        $arg1 = trim( $frame->expand( $args[0], PPFrame::NO_ARGS | PPFrame::NO_TEMPLATES ) );
    }

    // $arg1 contains the name of an existing array.
    $array = WSArrays::$arrays[$arg1]->getArray();

    // Manipulate array...

    // Arrays are stored in the variable $arrays, located in the WSArrays class.
    // If you do not save the array as a ComplexArray, existing parser functions will not work with this array.
    WSArrays::$arrays[$arg1] = new ComplexArray($array);

    return null;
}

Registering the extension

In order to enable the extension, you must add the extension name and aliases to WSArrays.i18n.php.

Add the following to $magicWords['en']: 

'<extensionname>' => [ 0, '<extensionname>' ],
'<alias1>' => [ 0, '<alias1>' ],
'<alias2>' => [ 0, '<alias2>' ],
...


Manipulation of the parser

WSArrays manipulates the Parser in several ways.

In order to use WSArrays to its fullest extend, it is important to know about this. This only applies to the following parser functions:

How WSArrays manipulates the parser

WSArrays manipulates the parser by using SFH_OBJECT_ARGS.

This way, the parser arguments are passed as PPNode objects instead of plain text. This allows for conditional expansion of the parse tree (see doc.wikimedia.org for more information). Using SFH_OBJECT_ARGS we can tell the parser to not parse the elements and return the raw text inputted by the user, which we can then parse in WSArrays.

How to control the manipulation

Different people have different needs, which is why we allow you to control the manipulation of the parser.

Again, this documentation only applies to the parser functions listed above.

By default, all input is automatically parsed by the parser before it is passed over to WSArrays (except for the 'map' in #complexarraymap and #complexarrayprint.) This allows you to use template parameters as well as magic words and templates when manipulating or defining arrays. This is however not always what you want. For instance, when you want to use a very complex template inside of an array, and you don't want to completely break when you use #complexarrayprint on it, you can tell WSArrays to not parse the input. If you then print the array, the template is printed as if it were enclosed with nowiki tags.

What if I want to parse the template later on?

Not parsing the template entirely is probably not what you want.

WSArrays tells the parser to parse the element when necessary, such as when using it in a map or when printing it as a value.

Arguments

You can include the following arguments as a comma-separated list in the 'noparse'-parameter of any applicable function.

Argument Result
NO_IGNORE Include the constant PPFrame::NO_IGNORE in the frame expansion.
NO_ARGS Include the constant PPFrame::NO_ARGS in the frame expansion.
NO_TEMPLATES Include the constant PPFrame::NO_TEMPLATES in the frame expansion, which tells the parser not to parse templates.
NO_TAGS Include the constant PPFrame::NO_TAGS in the frame expansion, which tells the parser not to parse tags.

Using WSArrays in other extensions

WSArrays provides an interface to easily use, manipulate and create arrays from any extension in the wiki.

Initialisation

In order to use the interface, include the ComplexArrayWrapper class into your extension, like so: 

include_once "/dir/to/ComplexArrayWrapper.php";

$interface = new ComplexArrayWrapper();

Getting the contents of an array

The contents of the array "foobar" can be retrieved like so: 

$array = $interface->on("foobar")->get();

Getting the contents of a subarray

The contents of "foobar[Foo][Bar]" can be retrieved like so: 

$array = $interface->on("foobar")->in(["Foo", "Bar"])->get();

Changing the contents of an array

The contents of the array "foobar" can be changed like so: 

$interface->on("foobar")->set(["foo", "bar" => ["baz", "bar"]]);

The contents of a specific value or subarray can also be changed like so: 

$interface->on("foobar")->in(["Foo", "Bar"])->set("Specific value");

// or

$interface->on("foobar")->in(["Foo", "Bar"])->set(["sub", "array"]);
If the array or subarray does not exist, they are automatically created. This is also the preferred way of creating a new array.

Unsetting an array

An array can be unset like so: 

$interface->on("foobar")->unsetArray();

Installation

  • Die Download und die Datei(en) in ein Verzeichnis namens WSArrays im Ordner extensions/ ablegen.
  • Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen: 
    wfLoadExtension( 'WSArrays' );
  • Konfiguriere nach Bedarf.
  •   Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.

Konfiguration

WSArrays has several configuration parameters.

$wfSkipVersionControl
Option to skip version control and force the initialization of WSArrays, accepts a boolean (default: false). This may crash your wiki.
$wfEnableResultPrinter
Option to enable the Semantic MediaWiki result printer, accepts a boolean (default: false). Setting this to true if you have not correctly installed the result printer (see #Installation) will result in your wiki not working.
