Any chance to have access to the actual values of a types while implementing interfaces?

Any chance to have access to the actual values of a types while implementing interfaces?

Awesome. That is exactly what I was lacking of with https://github.com/invopop/jsonschema cause it uses only reflect.Type internally and reflect.New().

Thanks!

Yeah, you don't need to do anything special for that, just supply a sample with values.

package main

import (
	"encoding/json"
	"fmt"
	"github.com/swaggest/jsonschema-go"
)

type S1 struct {
	A int `json:"a"`
	S S2  `json:"s"`
}

type S2 struct {
	B string `json:"b"`
}

func (s S2) JSONSchema() (jsonschema.Schema, error) {
	schema := jsonschema.Schema{}
	schema.AddType(jsonschema.Boolean)

	schema.WithDescription(s.B)

	return schema, nil
}

func main() {
	r := jsonschema.Reflector{}
	s, _ := r.Reflect(S1{S: S2{B: "test"}})
	j, _ := json.MarshalIndent(s, "", " ")

	fmt.Println(string(j))
}

{
 "definitions": {
  "S2": {
   "description": "test",
   "type": "boolean"
  }
 },
 "properties": {
  "a": {
   "type": "integer"
  },
  "s": {
   "$ref": "#/definitions/S2"
  }
 },
 "type": "object"
}
