Here's the issue related to nesting repeat() steps:
https://issues.apache.org/jira/browse/TINKERPOP-967
it's not clear from the comment where marko left that one exactly. anyway,
i'm not aware of anyone actively working on that.

We're using Neo4j as our underlying database, though we have no strong
attachment to it.
Are there roadmap plans to supporting nesting loops? (ie, a repeat under a
repeat)

Cool. I flip/flop back and forth about having better support for general
predicates (like text and geo) - seems like this would be a argument in
favor of adding such things to resolve this problem of having to write
server side DSL code. if done right it might save graph providers from
having to wr

We do not have any custom TraversalStrategies yet.
We do have custom predicates, though not many... Mostly string operations
(textContains, textRegex).

I think that's it's a bit early to say that definitively, but all community
discussion thus far has pointed in the direction of keeping DSLs a
client-side construct, so I'd expect that we would not do much work to
Now that python-gremlin is mature enough to use and extend, I'm working to
migrate our environment to a fully session-less, bytecode-based environment.
However, we currently have significant amounts of "legacy" groovy/gremlin
hanging around. Until all of that can be migrated, we still need to

yes - it might. i don't think we should go down that path though. first of

I think I figured out why 'label' isn't getting imported... It is being
overwritten in the import map by the __.label() method static import.
Normally, the CoreGremlinPlugin imports 'T.label' and '__.label()' is filtered
out of the imports on line 59 of ImportGroovyCustomizer.java (It was
Sorry - those imports are really mysterious to me. I dug through a fair bit
of groovy code trying to figure out what the rules were for that import
stuff and i don't recall getting to the bottom of it.

There was a time when I looked into that in pretty grave detail. I don't
recall my findings exactly, but I obviously didn't come up with a nice
solution. I'm not sure that I ever became convinced that any of this groovy
import stuff behaves in a completely deterministic way. I suppose you could

Thanks for fixing issue #1. I figured that one would be easy to fix.
As for issue #2, I'm wondering if changing the GremlinGroovyScriptEngine to add

rather than the end, would allow DSLs (and any other imports) to o

Hi all,
We are using the @GremlinDsl annotation to extend the Gremlin language into
our own DSL. I’ve run into two issues with anonymous traversals so far that
I’d like to bring up. One has a work-around, the other, I have not yet found a
work-around.
First (the one with the work-around):
