#i18n for nce

Description

Internationalization (not only) for the nce framework

How to install

Install with npm: npm install --save nce-i18n

Integrate in NCE:

var NCE = require("nce");
var nce = new NCE(/*{
  logger:{},
  fallbackLanguage: "en"
}*/);
var i18n = require("nce-i18n");
var ext = dummy(nce);
ext.install();
ext.activate();

Or use nce-extension-manager...

Install standalone

var i18n = require("nce-i18n");

var dict = i18n.Dictionary.create("name", {de:{hello:"Hallo", vsprintf: "Hallo %s"},en:{hello:"Hello", vsprintf: "Hello %s"}});

var translator = new i18n.Translator({targetLanguage:"en"});
translator(dict, "hello");

// Concat with other functions:
translator(dict, "hello", console.log); // -> undefined but get a console.log of Hello
translator(dict, "hello", console.log, "this is the second parameter for console.log"); // -> undefined but get a console.log of "Hello" and "this is the second parameter for console.log"
translator(dict, "vsprintf", require("sprintf").vsprintf, "World"); // -> Hello World

How to use

Basic funcitons for dictionary

createDictionary(name, dict, defaultLanguage)

Create a new dictionary.

removeDictionary(name)

Remove a dictionary by its name.

getDictionary

Get a dictionary by its name.

Basic funcitons for translator

__(dict, query, fn, args)

• First argument must be the dictionary or a dictionary name.
• The query should be a string with dot notation to query, or you are able to use different arguements as string
• The function (fn) is optional but must be a function!
• The arguments are optional and get passed to the function (fn). The result of the translation is the first argument!

Example

We have a dictionary called example with the following structure:

var ex = i18n.Dictionary.create("example", {
  en:{
    nested:{
      path: {
        for: {
          example: {
            string: "Result"
          }
        }
      },
      "path.for": {
        example: {
          string: "Another"
        }
      }
    }
  });

We are able to request the following ways:

translator.__("example", "nested.path.for.example.string"); // -> Result
translator.__(ex, "nested.path.for.example.string"); // -> Result
translator.__("example", "nested", "path", "for", "example", "string"); // -> Result
translator.__("example", "nested", "path.for", "example", "string"); // -> Another
translator.__("example", "nested", "path.for", "example.string"); // -> Another
translator.__("example", "nested", "path.for.example", "string"); // -> Result

We can use additional functions:

translator.__("example", "nested.path.for.example.string", console.log); // -> logs: Result
translator.__("example", "nested", "path.for", "example", "string" console.log); // -> logs: Another
translator.__("example", "nested", "path.for", "example.string", console.log, "example"); // -> logs: Another, example
translator.__("example", "nested", "path.for.example", "string", console.log, "works", "fine"); // -> logs: Result, works, fine

__n(dictionary, number, query, fn, args)

• First argument must be the dictionary or a dictionary name.
• The number of an element (1 is singular everything else is plural)
• The query should be a string with dot notation to query, or you are able to use different arguments as string
• The function (fn) is optional but must be a function!
• The arguments are optional and get passed to the function (fn). The result of the translation is the first argument!

Example

We have a dictionary called example with the following structure:

var n = i18n.Dictionary.create("enumeration", {
  en:{
    dog:{
      plural: "dogs",
      singular: "dog"
    }
  });

We are able to request the following ways:

translator.__n("enumeration", 1, "dog"); // -> dog
translator.__n(n, 1, "dog"); // -> dog
translator.__n(n, 2, "dog"); // -> dogs

Using functions and arguments for the function works the same way like using __!

__g(dictionary, gender, query, fn, args)

• First argument must be the dictionary or a dictionary name.
• The gender of an element (m is masculine, f is feminine)
• The query should be a string with dot notation to query, or you are able to use different arguments as string
• The function (fn) is optional but must be a function!
• The arguments are optional and get passed to the function (fn). The result of the translation is the first argument!

Example

We have a dictionary called example with the following structure:

var g = i18n.Dictionary.create("gender", {
  en:{
    dog:{
      feminine: "bitch",
      masculine: "dog"
    }
  });

We are able to request the following ways:

translator.__g("gender", "m", "dog"); // -> dog
translator.__g(g, "masculine", "dog"); // -> dog
translator.__g("gender", "f", "dog"); // -> bitch
translator.__g("gender", "feminine", "dog"); // -> bitch

Using functions and arguments for the function works the same way like using __!

Integrate in NCE

Config settings

You are able to use the following config-settings (listed with their defaults):

• fallbackLanguage: "en": Language to use, when no other requested language matches.
• logger: {}: Settings for logger-extension
