About

This module is a work in progress for allowing to use JavaScript

as an Automation based DSL to write custom extensions
to create "Automation chains"

Motivations

The initial idea comes from the following constations :

Automation Operations are a good High Level API : people succeed is doing amazing stuffs with it
Automation Chain control flow is too primitive
- loops are complex
- conditions are complex
- reusing "code segment" forces using several chains and makes maintenability more complex

So, the idea is to use a simple scripting language to manage the control flow and give accees to the Automation API.

Example :

Here is a example of an Automation Script :

var root = Document.Fetch(null, {
    "value": "/"
});

var newDocs = [];
for (var i = 1; i < 10; i++) {

    var newDoc = Document.Create(root, {
        "type": "File",
        "name": "newDoc" + i,
        "properties": {
            "dc:title": "New Title" + i,
            "dc:source": "JavaScript",
            "dc:subjects": ["from", "javascript"]
        }
    });
    var lastUUIDDigit = parseInt(newDoc.getId().slice(-1));
    if (lastUUIDDigit % 2 == 0) {
        newDoc = Document.Update(newDoc, {
            "properties": {
                "dc:nature": "even"
            }
        });
    } else {
        newDoc = Document.Update(newDoc, {
            "properties": {
                "dc:nature": "odd"
            }
        });
    }
    newDocs.push(newDoc);
}

var evenDocs = Document.Query(null, {
    "query": "select * from Document where dc:nature='even'"
});

println("Created " + evenDocs.size() + " even Documents");

Here is an exemple of an "Automation Chain" defined via a script

  <scriptedOperation id="Scripting.AddFacetInSubTree">
     <inputType>Document</inputType>
     <outputType>Documents</outputType>
     <param name="facet" type="string"/>
     <param name="type" type="string"/>

     <script><![CDATA[
       function run(ctx, input, params) {

         var query = "select * from " + params.type + " where ecm:path startswith '";
         query = query + input.getPathAsString();
         query = query + "'";

         //println("query = " + query);
         var subDocs = Document.Query(null, {
		"query": query
	   });

	   //println("Query run with " + subDocs.size() + " result");

	   var updated = [];
	   for (var i = 0; i < subDocs.size(); i++) {
	      var doc = subDocs.get(i);
	      if (!doc.hasFacet(params.facet)) {
	         doc.addFacet(params.facet);
	         updated.push(Document.Save(doc,{}));
	      }
	   }
         return updated;
       }
       ]]>
     </script>
  </scriptedOperation>

Resolution Order

[63, 779]

The resolution order represents the order in which components have been resolved by the Nuxeo Runtime framework. This range represents the minimal and maximal orders for this bundle's components.
You can influence this order by adding "require" tags in the component declaration, to make sure it is resolved after another component. It will also impact the order in which contributions are registered on their target extension point (see "Registration Order" on contributions).
