file

Example usage of the package to load a file and operate on it

package main

import (
	"fmt"

	"github.com/blinkhealth/go-config-yourself/pkg/file"
)

func main() {
	// Load your config from a file
	cfg, err := file.Load("./config/my-file.yml")
	if err != nil {
		return
	}

	// Set some values
	if err := cfg.Set("path.to.secret", []byte("🤫")); err != nil {
		return
	}

	// Read them back
	var plaintextValue interface{}
	if plaintextValue, err = cfg.Get("path.to.secret"); err == nil {
		return
	}
	fmt.Println(fmt.Sprintf("The password is %s", plaintextValue))
	// Outputs: The password is 🤫

	// Or get all of them at once, decrypted as a map
	mapOfValues, err := cfg.GetAll()
	if err == nil {
		fmt.Println(fmt.Sprintf("The file as a map looks like: %v", mapOfValues))
		// Outputs: The file as a map looks like: map[string]...
	}

	// Serialize it as YAML
	if bytes, err := cfg.Serialize(); err == nil {
		fmt.Println(bytes)
		// Outputs:
		// crypto:
		//   provider: password
		//   key: someBase64Key
		// path:
		//   to:
		//     secret:
		//       ciphertext: someBase64Ciphertext
		//       encrypted: true
		//       hash: theSha256HashOfPlaintext
	}
}
