             Summary: [freemarker-cli] Make usage of "DataSources" more "Freemarker" like
                 Key: FREEMARKER-148
                 URL: https://issues.apache.org/jira/browse/FREEMARKER-148
             Project: Apache Freemarker
          Issue Type: Task
            Reporter: Siegfried Goeschl
            Assignee: Siegfried Goeschl


"DataSources" is exposed to get/find documents - as suggested it would be nice to make the access more aligned with FreeMarker usage.

The way to go is to wrap "DataSources" and expose "TemplateSequenceModel" and "TemplateHashModel".

So accessing the first datasource would look like 

```
${GsonTool.toJson(YamlTool.parse(DataSources[0]))}
```

instead of 

```
${GsonTool.toJson(YamlTool.parse(DataSources.get(0)))}
```
