I really liked the idea of having the operators for parents and ancestors (etc.) look similar, but that turned out to be problematic when we want to add an infix operator for a DAG range (hg's `::` revset operator and git's `--ancestry-path` flag). Let's say we chose `:*:` as the operator. Part of the problem is how to parse `foo:*:bar` without eagerly parsing the `foo:`. It would also be nicer to use exactly the same operator as prefix, postfix, and infix. Since the "parents" operator can be repeated, we can't have it be just `:` and the "ancestors" operator be `::`. We could make the "ancestors" operator be something like `*:*` (or anything symmetric with the `:` symbol on the inside). However, at that point, the operator is getting ugly and hard to type. Another option would be to use `:` for ancestors and `::` for parents, but that is counterintuitive and get annoying if you want to repeat it. So it seems that the best option is to simply pick different symbols for parents/children and ancestors/descendants/range. This patch changes the ancestors/descendants operators to both be `,,`. I'm not at all attached to that particular symbol. I suspect we'll change it later. |
