#translate( id [,category ,lang] )
|
|
#Return translated string using translations files
|
|
|
|
#category and lang are set to current page.id and page.lang, but they can
|
|
#also be set manually to get translations for global layout and urls.
|
|
#Example: {% translate button-wallet layout %} will return the
|
|
#translated button-wallet string for the global layout file
|
|
|
|
#dynamic variables can be used as arguments
|
|
#Example: {% translate menu-{{id}} %}
|
|
|
|
#urls and anchors are automatically replaced and translated.
|
|
#Example: #vocabulary##[vocabulary.wallet] is replaced by
|
|
#/en/vocabulary#wallet when the page is in english or
|
|
#/fr/vocabulaire#porte-monnaie when the page is in french.
