Marko A. Rodriguez commented on TINKERPOP-1332:
-----------------------------------------------
I now have {{prettyPrint(int maxLineWidth)}} and in the GremlinConsole, that
line width is determined from JLine. Thus, we get it as such:
{code}
gremlin> g.V().out().out().out().out().repeat(out()).explain()
==>Traversal Explanation
=========================================================================================================================
Original Traversal [GraphStep(vertex,[]),
VertexStep(OUT,vertex), VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex), RepeatStep([VertexStep(OUT,vertex),
RepeatEndStep],until(false),emit(false))]
ConnectiveStrategy [D] [GraphStep(vertex,[]),
VertexStep(OUT,vertex), VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex), RepeatStep([VertexStep(OUT,vertex),
RepeatEndStep],until(false),emit(false))]
...
{code}
Make the window smaller in the same session and:
{code}
gremlin> g.V().out().out().out().out().out().explain()
==>Traversal Explanation
=======================================================================================
Original Traversal [GraphStep(vertex,[]),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex)]
ConnectiveStrategy [D] [GraphStep(vertex,[]),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex),
VertexStep(OUT,vertex)]
...
{code}
The {{toString()}} is simply {{prettyPrint(Integer.MAX_LENGTH)}}.
