The
ecrire/public/styliser.php file determines the name and type of the template depending on the arguments which are passed to it.
$styliser = charger_fonction('styliser', 'public');
list($skel,$mime_type, $gram, $sourcefile) =
$styliser($fond, $id_rubrique_fond, $GLOBALS['spip_lang'], $connect);
A 5th argument makes it possible to request a parser (a concrete syntax) and then consequently an extension for the various template files. By default, the parser (and therefore the extension applied) is
html.
The function searches for a template named
$fond.$ext in SPIP’s {path}. If it does not exist, it returns an error, otherwise it atempts to find a more specific template in the same directory as the template found, depending on the
id_rubrique and
lang parameters.
Styliser then searches files like
nom=8.html,
nom-8.html,
nom-8.en.html or
nom.en.html in the following order:
-*
$fond=$id_rubrique
-*
$fond-$id_rubrique
-*
$fond-$id_rubrique_parent_recursivement
-* then whichever it has found (or not) terminated with
.$lang
The function then returns a table of elements of what it has found
array($squelette, $ext, $ext, "$squelette.$ext") :
-* 1st parameter: the name of the template,
-* 2nd: its extension
-* 3rd: its grammar (the type of parser)
-* 4th: the full name.
These parameters are used by the composer and its
composer() function.
