+# Basilicom Extended Path Formatter Bundle for Pimcore
+
+###How it works
+This plugin provides a custom Pimcore path formatter as well as a simple, yaml-file-based configuration for the printed path for multi-relation-fields.  
+
+###Usage
+Add ``@Basilicom\PathFormatterBundle\DependencyInjection\BasilicomPathFormatter`` to the Formatter-Field in the relation-fieldType.  
+**Note:** The ``@`` is important, as the formatter is registered as a service, including dependency injection.
+
+Configure the pathformatter in your ``config.yml`` by using the first-level class-property-names in camelcase and between ``{`` and ``}``. The key between the braces will be used to call data object getters.  
+If no getter exists for the property, the pattern-part will stay untouched.
+
+As soon as a class property is a ``Pimcore\ModelAsset\Image`` it will be visible as small preview in the relation-list.
+
+####Example
+app/config/config.yml
+```
+basilicom_path_formatter:
+  pattern: "{logo} {identifier}"
+```
+
+var/classes/DataObject/Client.php
+```
+class Client extends Concrete
+{
+    protected $o_classId = "1";
+    protected $o_className = "Client";
+    protected $identifier;
+    protected $logo;
+    
+    /**
+     * Get identifier
+     *
+     * @return string
+     */
+    public function getIdentifier()
+    {
+        // ...
+    }
+    
+    /**
+     * Get logo
+     *
+     * @return \Pimcore\Model\Asset\Image
+     */
+    public function getLogo()
+    {
+        // ...
+    }
+}
+```
+
+### Todos
+- allow different patterns for different classes like e.g.:
+  ```
+  basilicom_path_formatter:
+    pattern: 
+        Pimcore\Model\DataObject\Client: "{logo} {identifier}"
+        Pimcore\Model\DataObject\Product: "{price}{unit}"
+  ```
+- add button to relation-fields to prefill the formatter class
+- implement helper methods for simple string modifications
+- allow output of nested properties like ``{productImage.fullPath}``
