-------------------------------------------
Summary: PythonTranslator should default to gremlin-groovy for
lambdas
Key: TINKERPOP-2493
URL: https://issues.apache.org/jira/browse/TINKERPOP-2493
Project: TinkerPop
Issue Type: Improvement
Components: translator
Affects Versions: 3.4.9
Reporter: Stephen Mallette
The Java {{PythonTranslator}} is generating the following by default:
{code}
gremlin>
pythonTranslator.translate(g.V().has("person",'name','marko').map(Lambda.function("x
-> x.get()"))).script
==>g.V().has('person','name','marko').map(lambda x -> x.get())
{code}
which is a native python lambda but in 3.5.0 the {{PythonScriptEngine}} is dead
(and likely never what the user would want/expect. We need to generate
gremlin-groovy by default and therefore:
{code}
gremlin>
pythonTranslator.translate(g.V().has("person",'name','marko').map(Lambda.function("x
-> x.get()"))).script
==>g.V().has('person','name','marko').map(lambda: "x -> x.get()")
{code}
