Developer's Guide for Internationalization (i18n)

NOTE: All the files you created should use UTF-8 encoding.

Steps to localize the UI in your language

1. Copy the file static/resources/js/services/i18n/locale_messages_en-US.js to a new file in the same directory named locale_messages_<language>_<locale>.js .

   The file contains a JSON object named locale_messages, which consists of key-value pairs of UI strings:

   var local_messages = {
      'sign_in': 'Sign In',
      'sign_up': 'Sign Up',
         ...
    };
   

   In the file locale_messages_<language>_<locale>.js, translate all the values into your language. Do not change any keys.

2. After creating your locale file, you should include it from the HTML page header template.

   In the file views/sections/header-include.htm, look for a if statement which switch langauges based on the current language (.Lang) value. Add in a else if statement for your language:

   {{ if eq .Lang "zh-CN" }}
      <script src="/static/resources/js/services/i18n/locale_messages_zh-CN.js"></script>
   {{ else if eq .Lang "en-US"}}
      <script src="/static/resources/js/services/i18n/locale_messages_en-US.js"></script>
   {{ else if eq .Lang "<language>-<locale>"}}
      <script src="/static/resources/js/services/i18n/locale_messages_<language>-<locale>.js"></script>
   {{ end }}
   

3. Add the new language to the I18nService module.

   In the file static/resources/js/services/i18n/services.i18n.js, append a new key-value item to the supportLanguages object. This value will be displayed in the language dropdown list in the UI.

    var supportLanguages = {
     'en-US': 'English',
     'zh-CN': '中文',
     '<language>-<locale>': '<language_name>'
    };
   

   NOTE: Don't miss the comma before the new key-value item you've added.

4. In the directory static/i18n/, copy the file locale_en-US.ini to a new file named locale_<language>-<locale>.ini. In this file, translate all the values on the right hand side into your language. Do not change any keys.

5. Add the new language to the app.conf file.

   In the file make/config/ui/app.conf, append a new item to the configuration section.

   	 [lang]
   	 types = en-US|zh-CN|<language>-<locale>
   	 names = en-US|zh-CN|<language>-<locale>
   

6. Next, change to make/ directory, rebuild and restart the Harbor by the below command:

       docker-compose down
       docker-compose up --build -d
