Jvalin: CLI for querying JSON data by path

Working with JSON on the commandline can be a pain. Jvalin is designed to make this easy by allowing you to query JSON using a path-style syntax.

For example, consider this JSON document:

{
  "people": [
    {"name": "Matt"},
    {"name": "Skippy", "age": 123}
  ]
}

The outer object contains an array with one entry. Say we want to get the name of the first person in the people list. We do that like this:

$ jv /people/0/name example.json
Matt

When possible, a query will return an individual value (as above), but it can also return partial JSON:

$ jv /people/1 example.json
{"age":123,"name":"Skippy"}

Building

JV uses Go 1.5+. Make sure you have that, then you can simply go get github.com/technosophos/jv.

To build from source, you can use go install or:

go build -o jv jv.go
