Miloslav Trmač d3f59bedb3 Update c/image to v4.0.1 and buildah to 1.11.3 This requires updating all import paths throughout, and a matching buildah update to interoperate. I can't figure out the reason for go.mod tracking github.com/containers/image v3.0.2+incompatible // indirect ((go mod graph) lists it as a direct dependency of libpod, but (go list -json -m all) lists it as an indirect dependency), but at least looking at the vendor subdirectory, it doesn't seem to be actually used in the built binaries.

gojsonpointer

An implementation of JSON Pointer - Go language

Usage

jsonText := `{
	"name": "Bobby B",
	"occupation": {
		"title" : "King",
		"years" : 15,
		"heir" : "Joffrey B"			
	}
}`

var jsonDocument map[string]interface{}
json.Unmarshal([]byte(jsonText), &jsonDocument)

//create a JSON pointer
pointerString := "/occupation/title"
pointer, _ := NewJsonPointer(pointerString)

//SET a new value for the "title" in the document     
pointer.Set(jsonDocument, "Supreme Leader of Westeros")

//GET the new "title" from the document
title, _, _ := pointer.Get(jsonDocument)
fmt.Println(title) //outputs "Supreme Leader of Westeros"

//DELETE the "heir" from the document
deletePointer := NewJsonPointer("/occupation/heir")
deletePointer.Delete(jsonDocument)

b, _ := json.Marshal(jsonDocument)
fmt.Println(string(b))
//outputs `{"name":"Bobby B","occupation":{"title":"Supreme Leader of Westeros","years":15}}`

The 4.Evaluation part of the previous reference, starting with 'If the currently referenced value is a JSON array, the reference token MUST contain either...' is not implemented.
