During my experimentation in creating Gremlin user-defined steps (https://github.com/tinkerpop/gremlin/wiki/User-Defined-Steps), I had a thought -- what if you could create a Gremlin step using any JVM language?
Well as it turns out, you can. I created a library that provides an example for how to write custom, user-defined Gremlin steps in Jython. The library is called mogwai, and it's on Github (https://github.com/espeed/mogwai). You should be able to adapt it for any JVM language. Here's the example code: Jython module: https://github.com/espeed/mogwai/blob/master/mogwai/steps/jython/Gizmo.py Java Interface: https://github.com/espeed/mogwai/blob/master/mogwai/interfaces/GizmoType.java Java Factory you can reuse for each Jython module: https://github.com/espeed/mogwai/blob/master/mogwai/factories/JythonFactory.java Groovy script that create the Gremlin steps: https://github.com/espeed/mogwai/blob/master/examples/gizmo.groovy Instructions on how to make this work: https://github.com/espeed/mogwai/blob/master/README And here's the corresponding thread in the Gremlin Users group (https://groups.google.com/d/topic/gremlin-users/wVTrJR1OMzQ/discussion). - James -- View this message in context: http://neo4j-community-discussions.438527.n3.nabble.com/Create-Custom-Gremlin-Steps-in-Any-JVM-Language-tp3275424p3275424.html Sent from the Neo4j Community Discussions mailing list archive at Nabble.com. _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
