Negation in JSON filter #32

Closed gauravphoenix closed 6 years ago

gauravphoenix commented 6 years ago

Following JSON path fails- $..book[?(!(@.price<10 && @.category=='fiction'))] while it works fine on http://jsonpath.com/.

Looking at the code seems like the JSON Path grammar (JsonPath.g4) doesn't have negation support. Are there plans for supporting it?

There is no concrete plan for it yet because I'm a little bit busy on other project recently. But Pull Requests are always welcomed for improving JsonSurfer.
