> Key: TINKERPOP-2050
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2050
> Project: TinkerPop
> Issue Type: Improvement
> Components: console
> Affects Versions: 3.2.9
> Reporter: Jim Hatcher
> Assignee: stephen mallette
> Priority: Minor
> Fix For: 3.4.0, 3.3.5

>
> I am working on a project where there is Java code being written to
> dynamically generate a Traversal based on a request coming in to an API. You
> can think of this as a "Traversal Builder."
> The code looks something like this:
> {code:java}
> Traversal<Vertex, Vertex> traversal = g.V();
> if (request.searchByAddress == true) {
> traversal.hasLabel("address");
> if (request.address.addressLine1 != null){
> traversal.has("address_line_1", request.address.addressLine1)
> }
> }
> etc.
> {code}
> When that code is being debugged, a traversal.toString() is run on the
> traversal to see the ouptut. This output is Gremlin bytecode.
> It would be nice to have a way to easily see the Gremlin Groovy that was
> built so that you could take the Groovy, drop it into Studio, make sure it
> runs, run a profile() on it, and make sure it's efficient.
> I figured out that you can do this by running this code:
> {code:java}
> private String toGremlinGroovyString(Traversal traversal){
> if (traversal == null){
> return null;
> }
> Bytecode bc = traversal.asAdmin().getBytecode();
> return GroovyTranslator.of("g").translate(bc);
> }
> {code}
> I think it would be nice to add that as a method on the Traversal class so
> that it could be used by driver users more easily.
> See comment below for information on the approach taken to help provide
> support in this area.
