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. In the folder src/portal/src/i18n/lang, copy json file en-us-lang.json to a new file and rename it to <language>-<locale>-lang.json .

   The file contains a JSON object including all the key-value pairs of UI strings:

   {
       "APP_TITLE": {
           "VMW_HARBOR": "Harbor",
           "HARBOR": "Harbor",
           ...
       },
       ...
   }
   

   In the file <language>-<locale>-lang.json, translate all the values into your language. Do not change any keys.

2. After creating your language file, you should add it to the language supporting list.

   Locate the file src/portal/src/app/shared/shared.const.ts. Append <language>-<locale> to the language supporting list:

   export const supportedLangs = ['en-us', 'zh-cn', '<language>-<locale>'];
   

   Define the language display name and append it to the name list:

   export const languageNames = {
       "en-us": "English",
       "zh-cn": "中文简体",
       "<language>-<locale>": "<DISPLAY_NAME>"
   };
   

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

3. Enable the new language in the view.

   Locate the file src/portal/src/app/base/navigator/navigator.component.html and then find the following code piece:

   <div class="dropdown-menu">
       <a href="javascript:void(0)" clrDropdownItem (click)='switchLanguage("en-us")' [class.lang-selected]='matchLang("en-us")'>English</a>
       <a href="javascript:void(0)" clrDropdownItem (click)='switchLanguage("zh-cn")' [class.lang-selected]='matchLang("zh-cn")'>中文简体</a>
   </div>
   

   Add new menu item for your language:

   <div class="dropdown-menu">
       <a href="javascript:void(0)" clrDropdownItem (click)='switchLanguage("en-us")' [class.lang-selected]='matchLang("en-us")'>English</a>
       <a href="javascript:void(0)" clrDropdownItem (click)='switchLanguage("zh-cn")' [class.lang-selected]='matchLang("zh-cn")'>中文简体</a>
       <a href="javascript:void(0)" clrDropdownItem (click)='switchLanguage("<language>-<locale>")' [class.lang-selected]='matchLang("<language>-<locale>")'>DISPLAY_NAME</a>
   </div>
