Hi,
So I downloaded and installed Jython 2.7.0.
This how easy it was to get Gremlin working in Jython.
import sys
sys.path.append("/Users/marko/software/tinkerpop/tinkerpop3/gremlin-console/target/apache-gremlin-console-3.2.1-SNAPSHOT-standalone/lib/commons-codec-1.9.jar")
sys.path.append("/Users/marko/software/tinkerpop/tinkerpop3/gremlin-console/target/apache-gremlin-console-3.2.1-SNAPSHOT-standalone/lib/commons-configuration-1.10.jar")
… lots of jars to add
sys.path.append("/Users/marko/software/tinkerpop/tinkerpop3/gremlin-console/target/apache-gremlin-console-3.2.1-SNAPSHOT-standalone/ext/tinkergraph-gremlin/lib/tinkergraph-gremlin-3.2.1-SNAPSHOT.jar")
from org.apache.tinkerpop.gremlin.tinkergraph.structure import TinkerFactory
graph = TinkerFactory.createModern()
g = graph.traversal()
g
g.V().hasLabel("person").out("knows").out("created")
g.V().hasLabel("person").out("knows").out("created").toList()
Then, the output looks like this:
>>> from org.apache.tinkerpop.gremlin.tinkergraph.structure import TinkerFactory
>>> graph = TinkerFactory.createModern()
>>> g = graph.traversal()
>>> g
graphtraversalsource[tinkergraph[vertices:6 edges:6], standard]
>>> g.V().hasLabel("person").out("knows").out("created")
[GraphStep(vertex,[]), HasStep([~label.eq(person)]),
VertexStep(OUT,[knows],vertex), VertexStep(OUT,[created],vertex)]
>>> g.V().hasLabel("person").out("knows").out("created").toList()
[v[5], v[3]]
Note that, of course, Jython's command line doesn't auto-iterate traversals.
Besides that -- sheez, that was simple.
The trick now is to use Jython idioms to make Gremlin-Jython be comfortable to
Python users…
Marko.
