+ * Provides a "~" operator used for ignore origin rules.
+ *
+ * It asserts that a subject matches a given regexp pattern, in a
+ * case-insensitive way.
+ *
+ * This operator will be used to compile ignore origin rules in PHP, usable
+ * directly on Entry objects for instance.
+ * It's registered in RulerZ using a service (wallabag.operator.array.pattern_matches);
