This module partly exists to prevent circular dependencies.
|
|
|
|
It also isolates some fairly yucky code related to the fact
|
|
that we have to support two formats of narrow specifications
|
|
from users:
|
|
|
|
legacy:
|
|
[["stream", "devel"], ["is", mentioned"]
|
|
|
|
modern:
|
|
[
|
|
{"operator": "stream", "operand": "devel", "negated": "false"},
|
|
{"operator": "is", "operand": "mentioned", "negated": "false"},
|
|
]
|
|
|
|
And then on top of that, we want to represent narrow
|
|
specification internally as dataclasses.
