Method Details

__construct() public méthode

Constructs a new instance of this Twig extension
public __construct ( Pico $pico )
$pico Pico current instance of Pico

getFilters() public méthode

Returns the Twig filters markdown, map and sort_by
See also: Twig_ExtensionInterface::getFilters()
public getFilters ( ) : Twig_SimpleFilter[]
Résultat Twig_SimpleFilter[] array of Pico's Twig filters

getKeyOfVar() public static méthode

Returns the value of a variable item specified by a scalar key or a arbitrary deep sub-key using a key path
public static getKeyOfVar ( array | Traversable | ArrayAccess | object $var, mixed $keyPath ) : mixed
$var array | Traversable | ArrayAccess | object base variable
$keyPath mixed scalar key or a array interpreted as key path (when passing e.g. ['foo', 'bar'], the method will return $var['foo']['bar']) specifying the value
Résultat mixed the requested value or NULL when the given key or key path didn't match

getName() public méthode

Returns the name of the extension
See also: Twig_ExtensionInterface::getName()
public getName ( ) : string
Résultat string the extension name

getPico() public méthode

Returns the extensions instance of Pico
See also: Pico
public getPico ( ) : Pico
Résultat Pico the extensions instance of Pico

mapFilter() public méthode

This method is registered as the Twig map filter. You can use this filter to e.g. get all page titles ({{ pages|map("title") }}).
public mapFilter ( array | Traversable $var, mixed $mapKeyPath ) : array
$var array | Traversable variable to map
$mapKeyPath mixed key to map; either a scalar or a array interpreted as key path (i.e. ['foo', 'bar'] will return all $item['foo']['bar'] values)
Résultat array mapped values

markdownFilter() public méthode

This method is registered as the Twig markdown filter. You can use it to e.g. parse a meta variable ({{ meta.description|markdown }}). Don't use it to parse the contents of a page, use the content filter instead, what ensures the proper preparation of the contents.
public markdownFilter ( string $markdown ) : string
$markdown string markdown to parse
Résultat string parsed HTML

sortByFilter() public méthode

This method is registered as the Twig sort_by filter. You can use this filter to e.g. sort the pages array by a arbitrary meta value. Calling {{ pages|sort_by("meta:nav"|split(":")) }} returns all pages sorted by the meta value nav. Please note the "meta:nav"|split(":") part of the example. The sorting algorithm will never assume equality of two values, it will then fall back to the original order. The result is always sorted in ascending order, apply Twigs reverse filter to achieve a descending order.
public sortByFilter ( array | Traversable $var, mixed $sortKeyPath, string $fallback = 'bottom' ) : array
$var array | Traversable variable to sort
$sortKeyPath mixed key to use for sorting; either a scalar or a array interpreted as key path (i.e. ['foo', 'bar'] will sort $var by $item['foo']['bar'])
$fallback string specify what to do with items which don't contain the specified sort key; use "bottom" (default) to move those items to the end of the sorted array, "top" to rank them first, or "keep" to keep the original order of those items
Résultat array sorted array
