Extension:WSArrays/ja

The WSArrays (or ComplexArrays) extension creates an additional set of parser functions that operate on multidimensional and associative arrays.

関数
This extension defines over 20 parser functions:

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

説明

 * 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 ).

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

説明

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

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

説明

 * 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.

例
We have an array called 'foobar':


 * 0
 * foo: bar
 * baz: quz
 * 1
 * foo: quz
 * baz: bar
 * 2
 * baz: bar

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 ). 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 to iterate over the array and print each value seperately, but we can also use a Wairudokado operator in the #complexarrayprint function.

Semantic MediaWiki
This extension introduces a new format for displaying Semantic MediaWiki results. In order to use the new format, use. Because the result printer defines a new complexarray, you need to provide a name for that array using ; if   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, you must first check if you have set   to. 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  from the extension's root folder to.

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. 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  would be. The class must implement at least the following methods:

Returning the result
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.

or when using :

Registering the extension
In order to enable the extension, you must add the extension name and aliases to.

Add the following to :

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 and .) 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 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.

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  class into your extension, like so:

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

Getting the contents of a subarray
The contents of "foobar[Foo][Bar]" can be retrieved like so:

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

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

Unsetting an array
An array can be unset like so:

Configuration
WSArrays has several configuration parameters.


 * Option to skip version control and force the initialization of WSArrays, accepts a boolean (default: false). This may crash your wiki.
 * Option to skip version control and force the initialization of WSArrays, accepts a boolean (default: false). This may crash your wiki.


 * 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 ) will result in your wiki not working.
 * 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 ) will result in your wiki not working.
