Initialization of 'g' and 'graph' vars on server start

Upon starting gremlin console, the g and graph objects aren't being automatically instantiated. From reading it seems that I don't have something configured correctly to allow for this during startup.

I've checked my gremlin-server.yaml file, which includes

graphs: {
  graph: conf/gremlin-server/dynamodb.properties}

I'm able to manually create the objects in the console, so it does work

gremlin> graph = TitanFactory.open('conf/gremlin-server/dynamodb.properties');
==>standardtitangraph[com.amazon.titan.diskstorage.dynamodb.DynamoDBStoreManager:[127.0.0.1]]
gremlin> mgmt = graph.openManagement();
==>com.thinkaurelius.titan.graphdb.database.management.ManagementSystem@433b546f
gremlin> g = graph.traversal(standard());
==>graphtraversalsource[standardtitangraph[com.amazon.titan.diskstorage.dynamodb.DynamoDBStoreManager:[127.0.0.1]], standard]

Is there something else I'm missing? I found this issue logged on the gremlin-javascript project, but am still stuck. I think my problem is with my configuration on the server and not my implementation of gremlin-javascript.

Ultimately I'm trying to traverse using gremlin-javascript, but I'm forced to create 'graph' and 'g' each time (slow).

This is the expected behavior when starting the Gremlin console, unless you start it with an init script that does this for you:

// scripts/initMyGraph.groovy

graph = TitanFactory.open('conf/gremlin-server/dynamodb.properties')
g = graph.traversal(standard())

Then start the console with:

bin/gremlin.sh scripts/initMyGraph.groovy

Graph and Traversal objects will be accessible as graph and g variables in the console, respectively.
