Cool. Although I prefer to start behind V() (at least 5 spaces in the
second line), UNLESS I have a mid-traversal V().
3. Barriers form line breaks.
Not cool. Long lines form line breaks. Sometimes I make it depend on the
steps I'm using, but the types of steps usually don't play a role.
4. by()-modulators form indented "paragraphs."
Nah, kinda don't like your style. I will show my variant at the end of that
message.
5. Standard filters.maps.flatmaps are single line until it gets unwieldy.
Again, the line length is all that really matters.
Here's my variant:
g.V().out("knows").out("attended").
group().by("state").by().
select("Vermont").unfold().
in("attended").has("gpa").
V().foo().bar().whatever().
order().by("age",decr).
by("gpa",incr).
limit(10).values("name").
Besides that, I think that choose() is kinda special:
.choose(condition(), then().do().this(),
else().do().that())
Cheers,
Daniel
