[jira] [Commented] (TINKERPOP-1409) Make the "null" return in the gremlin console into something more understandable

["ASF GitHub Bot (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TINKERPOP-1409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15493852#comment-15493852 ] 

ASF GitHub Bot commented on TINKERPOP-1409:
-------------------------------------------

GitHub user spmallette opened a pull request:

    TINKERPOP-1409 Print no result line if empty.result.indicator is empty string.

    https://issues.apache.org/jira/browse/TINKERPOP-1409
    
    This seems like a better use of the empty string setting than to actually just print an empty string line.
    
    ```text
    gremlin> graph = TinkerGraph.open()
    ==>tinkergraph[vertices:0 edges:0]
    gremlin> graph.close()
    ==>null
    gremlin> graph = TinkerGraph.open()
    ==>tinkergraph[vertices:0 edges:0]
    gremlin> :set empty.result.indicator ""
    gremlin> graph.close()
    gremlin> 
    ```
    
    Pretty small change, but, I didn't CTR this in case someone didn't really like this behavior.  If there are -1s I can just kill this and close the JIRA currently hanging out there as I only kept it open because I saw this dangling issue I wanted to implement.

> A common question among new users is what is with the "null" return String in the console when there is a successful execution.  An explanation is in the docs now (see note at bottom of http://tinkerpop.apache.org/docs/current/reference/#_mutating_the_graph section) but it would be nice to avoid it or make it more immediately understandable for new users.
> It's not a huge deal, but often comes up as a question from new users.
