Breaking change SimplerPathStep and CyclicPathStep
Hello,
Please see:
https://github.com/apache/tinkerpop/pull/574 <https://github.com/apache/tinkerpop/pull/574>
SimplePathStep and CyclicPathStep have been generalized to PathFilterStep and now we have to(), from(), and by() modulation support for both simplePath() and cyclicPath(). Minor breaking change that will more than 99% likely not effect any providers and if it does, a simple name change would do the fix.
Heads up,
Marko.

Hey,
Check it out.
gremlin> g.V().as('a').out().as('b’). // COULD ALWAYS DO
simplePath().
path().by('name')
==>[marko,lop]
==>[marko,vadas]
==>[marko,josh]
==>[josh,ripple]
==>[josh,lop]
==>[peter,lop]
gremlin> g.V().as('a').out().as('b’). // CAN NOW DO
simplePath().by(label).
path().by('name')
==>[marko,lop]
==>[josh,ripple]
==>[josh,lop]
==>[peter,lop]
So we added by()-modulation to simplePath() and cyclicPath(). Now, like path().by()-modulation, you can first project the path and then determine whether its a cyclic or simple projection.
Moreover, add that goodness with from().to()-modulation support for path(), simplePath(), and cyclicPath().
gremlin> g.V().as('a').out().as('b').out().as('c’). // COULD ALWAYS DO
path().by('name')
==>[marko,josh,ripple]
==>[marko,josh,lop]
gremlin> g.V().as('a').out().as('b').out().as('c’).
path().by('name').from('a').to('b’) // CAN NOW DO
==>[marko,josh]
==>[marko,josh]
And drum roll please… <…Billy Jean is a really good song />
gremlin> g.V().as('a').out().as('b').out().as('c’).
simplePath().by(label).
path().by('name')
gremlin>
gremlin> g.V().as('a').out().as('b').out().as('c’).
simplePath().from('b').to('c').by(label).
path().by('name')
==>[marko,josh,ripple]
==>[marko,josh,lop]
Na na!

Well I meant every word I said.
When I said that "I love you" I meant that I’d love you forever.
Cause I’m going to keep on loving you!
Cause its the only thing I want to do!
I don’t want to sleep, I just want to keep on lovin’ you!
