During the normal execution of several commands, call-outs are made to optional scripts that allow a developer to add functionality or checking. Typically, the hooks allow for a command to change the values of function arguments before any other call, and allow for a post-processing treatment that will always change the function result.

Exemple :

function prefix_treatment($flow) {
/* add something to the flow */
$flow .= 'This is some html code';
return $flow;
}

plugin.xml defines the implemented hooks with a list of tags :

point_entree
fonction
fichier.php

•  : name of the hook (from a list defined in ecrire/inc_version.php)
  
•  : function name without it’s prefix
  
•  : file name that defines the previous function. It’s name must be prefix_action
