The ArrayFunctions extension creates an additional set of pure, Parsoid-compatible (see here) parser functions that perform operations on arrays. These parser functions are pure, meaning they do not modify any previously defined arrays and only return a result based on their input arguments.

Installation

• Download and move the extracted ArrayFunctions folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/ArrayFunctions
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'ArrayFunctions' );
  // Increase $wgMaxArticleSize to allow for larger arrays (default: 2048)
  $wgMaxArticleSize = 8192;
  

•  Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

FAQ

How can I define an array to be used throughout a page?

It is not possible to directly define an array to be used throughout a page, because this would require sequential processing of extension tags, which is not supported by Parsoid (see Parsoid/Extension API#No support for sequential, in-order processing of extension tags). Instead, you can pass arrays around as template parameters:

{{My template|{{#af_list:a|b|c}}}}

This way, the array is available in Template:My template as {{{1}}}.

How to iterate over an array?

It is possible to iteratively access elements of an array using #af_foreach:

{{#af_foreach:{{#af_list:red|green|blue}}||color|<nowiki/>
* {{{color}}} is my favourite.
}}

The expected output from the snipped above is:

• red is my favourite.
• green is my favourite.
• blue is my favourite.

Why are values not recognized as arrays?

This may happen because your arrays are too large. MediaWiki internally keeps a counter on the total size of template arguments, which can be increased by increasing $wgMaxArticleSize.

How is this different from extensions such as Arrays or Variables?

The main difference between ArrayFunctions and those extensions is that ArrayFunctions parser functions are pure. This means that instead of modifying or declaring a variable, the parser function directly outputs its result.

For example with #af_map, the given array is not modified; instead, a copy is created, modified and then outputted. No parser function in ArrayFunctions modifies global state: all computation happens solely with the invocation of the parser function. This makes working with ArrayFunctions very different from working with other extensions such as Arrays or Variables. Instead of imperatively modifying an array stored in a variable, function composition must be used to perform more complex operations. For example:

Arrays

{{#arraydefine: fruits | orange, banana, strawberry, apple }}
{{#arraysort: fruits | asc }}
{{#arrayprint: fruits }}

ArrayFunctions

{{#af_print: 
    {{#af_sort: 
        {{#af_list: orange | banana | strawberry | apple }}
    }}
}}

Why is whitespace trimmed from array values?

Whitespace is inherently implicit in wikitext. In order to be consistent with this behaviour, whitespace is recursively trimmed from array values.

Functions

This section uses Python's notation for variadic parameters. A parameter prefixed with a single asterisk (*) denotes that a variable number of positional arguments can be passed, and a parameter prefixed with a double asterisk (**) denotes that a variable number of named arguments can be passed.

The extension defines the following parser functions, Lua functions and magic words:

Construct an array or value

Extract information from an array

Create an array from an existing array

Iterate over an array

Miscellaneous functions

Notes

• All keyword argument names are case-sensitive.
• All string arguments support the following escape sequences:

\s for spaces

\n for newlines

\\ for backslashes

length : integer, optional

The length of the slice. If the length is given and positive, then the slice will have that many elements in it. If the length is given and negative, then the slice will stop that many elements from the end of the array. If it is omitted, then the slice will have everything from offset up until the end of the array.

{{#af_print: {{#af_unset: {{#af_object: foo={{#af_object: bar=quz | far=buz }} }} | foo | bar }} }}

Scribunto

This extension is particularly useful in combination with Lua, as it can be used to create the array containing data required for the presentation of the page. This array can be exported to work with ArrayFunctions:

local p = {};

function p.world()
	return mw.af.export({
		["Hello"] = "World"
	});
end

return p;

This module may then be invoked like so:

{{#af_print: {{#invoke: Hello | world }} }}

mw.af.export

This Lua function exports a Lua table as an ArrayFunctions array.

Description

mw.af.export( table )

Parameters

table : array

The array to export.

Return values

Returns the table as an ArrayFunctions array.

mw.af.import

This Lua function imports an ArrayFunctions array as a Lua table.

Description

mw.af.import( array )

Parameters

array : array

The array to import.

Return values

Returns the array as a Lua table.

Magic words

The extension defines a number of magic words (variables).

AF_EMPTY

This magic word returns the empty array. This is useful, because it is not possible to create an empty array with #af_list or #af_object.

Description

{{AF_EMPTY}}

Return values

Returns the empty array.
