Usage

Adding the Dependency

The artifact is published on Maven Central Repository. If you are using Maven, add the following dependency.

<dependency>
    <groupId>dev.akkinoc.util</groupId>
    <artifactId>yaml-resource-bundle</artifactId>
    <version>${yaml-resource-bundle.version}</version>
</dependency>

Creating Resource Files

Create a YAML-formatted resource file on the classpath. Also, create locale-specific resource files as needed.

For example (resource.yml, resource_en.yml, resource_fr.yml, etc):

fruits:
  apple: Apple
  orange: Orange
  grape: Grape
colors:
  - Red
  - Orange
  - Purple

Accessing the Resource

Access the resource via YamlResourceBundle.

For example in Java:

import dev.akkinoc.util.YamlResourceBundle;

// Gets the resource bundle
// YamlResourceBundle.Control is specified for ResourceBundle.Control
ResourceBundle bundle = ResourceBundle.getBundle(
        "resource", YamlResourceBundle.Control.INSTANCE);

// Gets the map values
System.out.println(bundle.getString("fruits.apple"));   // => "Apple" or localized value
System.out.println(bundle.getString("fruits.orange"));  // => "Orange" or localized value
System.out.println(bundle.getString("fruits.grape"));   // => "Grape" or localized value

// Gets the list values
System.out.println(bundle.getString("colors[0]"));      // => "Red" or localized value
System.out.println(bundle.getString("colors[1]"));      // => "Orange" or localized value
System.out.println(bundle.getString("colors[2]"));      // => "Purple" or localized value

// Gets the list values as an array
System.out.println(Arrays.toString(bundle.getStringArray("colors")));
// => "[Red, Orange, Purple]" or localized values

// Gets the all keys
System.out.println(bundle.keySet());
// => "[fruits.apple, fruits.orange, fruits.grape,
//      colors, colors[0], colors[1], colors[2]]" (not sorted)
