Go Introspection

Yaml file (test.yaml) :

---
a: 1

vars:
  hello: world
  number: 2

1.2:
  - str1a: "string 1 a"
    str1b: "string 1 b"
  -
    - a
    - b
    - c
  - str2a: "string 2 a"
    str2b:
  - "string 3"

Code :

package main

import (
    "fmt"
    "io/ioutil"
    "gopkg.in/yaml.v3"

    "github.com/cgeninet/introspect"
)

func main() {
    // Load Yaml file
    yamlFile, _ := ioutil.ReadFile("test.yaml")
    data := make(map[interface{}]interface{})
    yaml.Unmarshal(yamlFile, &data)

    is := introspect.NewStruct(data, "/")
    for _, k := range is.Keys() {
        fmt.Println("path", k, "has value :", is.Value(k))
    }
}

Result :

path /1.2/2/str2a has value : string 2 a
path /1.2/3 has value : string 3
path /1.2/1/0 has value : a
path /1.2/1/1 has value : b
path /vars/number has value : 2
path /1.2/0/str1a has value : string 1 a
path /1.2/0/str1b has value : string 1 b
path /1.2/1/2 has value : c
path /a has value : 1
path /vars/hello has value : world
