spmallette opened a new pull request, #3626:
URL: https://github.com/apache/tinkerpop/pull/3626
The Until Step section of the reference documentation was a two-sentence
stub that deferred entirely to `repeat()`, with no example and no mention of
what `until()` actually controls.
This expands it to mirror the existing Times Step section in shape and tone.
`until()` is a step modulator for `repeat()`, so the section stays lean and
defers the general loop semantics to the `repeat()`-step section rather than
duplicating them:
- A short intro paragraph describing `until()` as a step modulator for
`repeat()` that specifies the break condition controlling how long the
`repeat()` body loops, with no effect on its own.
- A one-sentence note on the two overloads: `until(Predicate)` tests the
traverser directly, while `until(Traversal)` tests whether its child traversal
produces a result.
- One runnable example, `g.V(1).repeat(out()).until(has('name','ripple'))`.
- A sentence noting that placing `until()` before or after `repeat()`
determines while-do versus do-while semantics, deferring to the `repeat()`-step
section for the positioning details.
The existing Additional References links are preserved unchanged. Only the
until-step section is touched.
