The |abs_url filter (since SPIP 1.8.2) combines the actions of the |liens_absolus and |url_absolue filters, and can therefore also be applied to a text tag like (#TEXTE, #DESCRIPTIF, etc.) as well as a URL type tag like (#URL_ARTICLE, #URL_RUBRIQUE, etc.), and it will transform all inks into absolute links (with the site’s complete URL address).
See also the |url_absolue and |liens_absolus filters.
