For this specific example you can use the path step, something like ".path{
it.getId() }
this should return [current_id, a_id, b_id, c_id, d_id] for each path.
if you need to edge and vertex data and have to process that data
differently, you can do something along the lines of
".path{ if (it.getElementType() == "Vertex") { [vertex stuff] } else {
[edge stuff] } }"

If you are writing gremlin scripts and need even more complex processing,
you can use ".sideEffect{ }" to add data to a map or something as you go
traverse the path.
