l20n

A localization library for Firefox OS

L20n: Localization 2.0 Build Status

L20n reinvents software localization. Users should be able to benefit from the entire expressive power of a natural language. L20n keeps simple things simple, and at the same time makes complex things possible.

L20n.js is a localization framework for websites which want to offer a best-in-class translation experience for their users. L20n takes advantage of modern web technologies to offer a fast and lean localization of HTML and JavaScript.

How to use L20n

Include the following code in the <head> section of your HTML:

<meta name="defaultLanguage" content="en-US">
<meta name="availableLanguages" content="de, en-US, fr, pl">
<link rel="localization" href="locales/myApp.{locale}.ftl">
<script defer src="dist/bundle/web/l20n.js"></script>

L20n is targeted at modern browsers. See docs/compat for documentation on how to enable support for legacy browsers.

What L20n's syntax looks like

A straight-forward example in English:

brand-name = Firefox
about      = About { brand-name }
settings   = { brand-name } Settings

And the same thing in Polish:

brand-name =
 *[nominative]   Firefox
  [genitive]     Firefoksa
  [dative]       Firefoksowi
  [accusative]   Firefoksa
  [instrumental] Firefoksem
  [locative]     Firefoksie
about      = O { brand-name[locative] }
settings   = Ustawienia { brand-name[genitive] }

Localizing Web content with HTML Bindings

You can take advantage of HTML bindings to localize your HTML documents with L20n. See docs/html for documentation and examples.

The JavaScript API and documentation

It is also possible to use L20n programmatically, for instance in order to localize dynamic content. Refer to docs/node and docs/view for more details.
