Support for internationalization

[pastarace]

Hi is the internationalization supported in Recline? Thanks Paolo

@pstarace we haven't done it at present though it would be fairly straightforward to do.

Anyone want to have a stab at it or sponsor it?

[KrzysztofMadejski]

We (with @danielmacyszyn) may code it. Do you have any recommendations for the translation lib to use?

I've found these so far:

http://i18next.com/ http://formatjs.io/ ! https://github.com/wikimedia/jquery.i18n http://slexaxton.github.io/Jed/ (used in ckan) https://github.com/messageformat/messageformat.js - a successor to Jed http://l10ns.org/ http://fhtr.org/js-i18n/

[rufuspollock]

No particular preference. Jed seems reasonable and ckan uses it so maybe good to go with that.

I have a working early draft, still some work needs to be done.

I've chosen FormatJS.io because:

• Jed is no longer supported, there is a new lib from the same author
• I was checking FormatJS.io vs i18next (both have 10x more npm usage than the Jed successor) and:
• author of the Jed collaborates a bit on FormatJS
• FormatJS.io is supported by Yahoo
• has utf-8 support and uses ICU Message syntax standard

The end goal is to have a separate FormatJS.io Backbone+Moustache integration as an independent library used in Recline.

@KrzysztofMadejski sounds really good.

It would be great if someone could review my code. I'm almost ready, I'm missing:

• [ ] separate MustacheFormatter
• [x] have global singleton object per locale and any library to store messages; usage would be like I18n.formatter('recline','pl').t('Add_row')
• [x] have a way to extract current locale and pass to templates .. I'm wondering how to do that? A singleton keeping current locale? That could allow for dynamic locale changes in future. Is there any browser-standard way to query current locale in Javascript?

EDIT: Apparently there is no standard way to do it: "The working group discussed extensively whether there should be an API to set a default locale list that would then be used throughout the Internationalization API. Two issues prevent this: First, a settable default locale list would create a global communication channel between different scripts running within the same environment, which is considered a security risk. Second, an application may include different components, such as embedded apps, that need different default locales. ECMAScript has no knowledge of these components and no way to manage appropriate contexts for them" - http://norbertlindenberg.com/2012/12/ecmascript-internationalization-api/index.html
