Title: [FR] Request object in Granite Expression Language
Description: It would be nice to be able to get information about the request object in granite EL. These could be passed as parameters like ${remoteUser} or ${request.remoteUser}. Similar to how we have access to url information and state and tenant information. This would be useful when creating new consoles, such as a datasource for getting a list of pages created by the end user (for a news system in my case). Currently, I have to set a property on the node to something like "self" and then use request.getRemoteUser() in the corresponding jsp for the sling:resourceType. This would save a step. Granite is already able to handle access to nodes based on privilege, so user-oriented functionality exists in the system as is, so I don't feel this is opening up a good deal of new functionality.
How important it is for you? : Minor to moderate, it would speed up develop in some cases to have access to this data.
AEM Version: 6.2
Extra Information: Here's an before and after example of the functionality from a datasource I created to pull news pages, if the end user were passed as a parameter instead of "current" it would save the nested if-statement.
... String author = dsCfg.get("author", ""); Map<String,String> map = new HashMap<String, String>(); map.put("path",nss.getArticlesPath()); map.put("type", "cq:Page"); map.put("p.limit","" + limit); map.put("p.limit","" + offset); map.put("1_property","jcr:content/sling:resourceType"); map.put("1_property.value","news/components/structure/story"); map.put("orderby", sortName); map.put("orderby.sort",sortDir); map.put("orderby.case","ignore"); if(!author.equals("")) { map.put("2_property","jcr:content/author"); if(author.equals("current")) { map.put("2_property.value",request.getRemoteUser()); } else { map.put("2_property.value",author); } } ...Or, if the node has an author property set to "${request.remoteUser}"
... String author = dsCfg.get("author", ""); // Map<String,String> map = new HashMap<String, String>(); map.put("path",nss.getArticlesPath()); map.put("type", "cq:Page"); map.put("p.limit","" + limit); map.put("p.limit","" + offset); map.put("1_property","jcr:content/sling:resourceType"); map.put("1_property.value","news/components/structure/story"); map.put("orderby", sortName); map.put("orderby.sort",sortDir); map.put("orderby.case","ignore"); if(!author.equals("")) { map.put("2_property","jcr:content/author"); map.put("2_property.value",author); } ...
