JSONPath for go-cty: peekcty

peekcty lets you iterate over cty datastructures using JSONPath syntax.

Note: go-cty is the serialization / typesystem library for Go powering HCL, Terraform, zclconf.

Example

Given text_fixture_cars.json:

import "github.com/clean8s/peekcty"

func demo() {
  p, err := peekcty.NewPath("$..has")
  fmt.Println(p.Search(carExample))
}

Prints:

".carOwners.A.has" => []{StringVal("Honda Accord"), StringVal("VW Up"), StringVal("Porsche 911")}
".carOwners.B.has" => []{StringVal("Renault Clio"), StringVal("Jaguar F-Type"), StringVal("Dodge Viper")}
".cars[0].has" => []{StringVal("4 doors")}

Implementation

It's based on Kubernetes/kubectl's implementation here. With two differences:

• it doesn't require templates or range blocks
• it operates on cty.Value instead of reflect.Value

You can use all features except for filters:

• $[0, 1]
• $.field
• $.wildcard[*]
• $.x.y..recursive
• m[1:], slice2[:2], slice3[1:5]
