A JavaScript locale library that can be used to render dates, date and date-time intervals, numbers, lists, and more. Also contains localized display names for countries, regions, languages, time zones, and currencies. Most of the informations comes from the Unicode CLDR (Common Localization Data Repository) and is extracted using the cldr module.
Make sure you have node.js and npm installed, then run:
$ npm install -g inter
To use inter in node.js, just require the library and use the load
method to get an inter object with information about a specific
locale:
var localeId = 'en_US',
inter = require('inter').load(localeId);
In the browser you'll most likely want to build a version with only
the specific features and locales you need. There's a buildInter
script in the package that's useful for that. You can build one
completely self-contained file per locale by specifying --type browser.
You can also build a single file with the data for all locales using
--type bundle. The active locale will be determined by the value of
the LOCALEID variable when the bundle is loaded into the
browser. This is tailored especially for assetgraph-builder
with the --locales switch. Working with a single file is convenient
during development. When doing a production build UglifyJS' dead code
elimination will be used to strip the library down after
buildProduction has created separate versions of your JavaScript
for each locale.

The library must be built with the --rbnf switch.
Determine the locale's plural form for a given number, eg. "one",
"two", "few", "zero", "many", or "other".
See the LDML spec for more information.
The library must be built with the --pluralrules switch.
Render a list of items using the list patterns. The locale library must be built with the --listpatterns switch.
Example:
inter.renderList(['foo', 'bar', 'quux']); // "foo, bar, and quux" (en_US).
Render (or get a renderer function for) a specific unit of time. The
locale library must be built with the --dateformats switch.
Example:
inter.getUnitRenderer('week')(1); // '1 week' (en_US)
inter.getUnitRenderer('month')(5); // '5 months' (en_US)
inter.renderUnit(1, 'week'); // '1 week' (en_US)
Render (or get a renderer function for) a number according to the specified ICU DecimalFormat (defaults to the locale standard number format for the locale).
Render (or get a renderer function for) a percentage according to the
number format and percent char of the locale. The library must be
built with the --numberformats switch.
Example:
inter.getPercentageRenderer(1)(1.0056); // '105.6 %' (en_US)
inter.renderPercentage(1.0056, 1); // '105.6 %' (en_US)
Render (or get a renderer function for) a number of bytes according to
the number format of the locale. The units themselves (bytes, KB, MB,
etc.) aren't localized yet, sorry. The library must be built with the
--numberformats switch.
Example:
inter.getFileSizeRenderer(1)(100000); // '97.7 KB' (en_US)
inter.renderFileSize(100000, 1); // '97.7 KB' (en_US)
Render (or get a renderer function for) one of the locale's standard
full/long/medium/short time or date formats, or a locale-specifc
format specified by a CLDR
dateFormatItem id. The library must be built with the
--dateformats switch.
Examples:
var aprilFourth = new Date(2010, 3, 4);
inter.getDateRenderer('mediumTime')(new Date(2010, 5, 7, 22, 30); // '10:30:00 pm' (en_US)
inter.getDateRenderer('longDate')(new Date(2010, 5, 7, 22, 30); // 'June 7, 2010' (en_US)
inter.renderDate(aprilFourth, 'fullDate'); // "Sunday, April 4, 2010" (en_US)

Render (or get a renderer function for) a date or date-time interval
that uses one of the locale's standard full/long/medium/short time or
date formats, or a locale-specific format specified by a CLDR
dateFormatItem id (see some
examples). The library must be built with the
--dateintervalformats switch.
Examples:
var dateIntervalRenderer = inter.getDateIntervalRenderer("yMMMM"),
januaryThroughApril = {start: new Date(2010, 0, 1), end: new Date(2010, 4, 0)};
dateIntervalRenderer(januaryThroughApril); // "January-April 2010" (en_US)
inter.renderDateInterval({
start: new Date(2012, 9, 7, 9, 30),
end: new Date(2012, 9, 7, 11, 30)

Example:
inter.tokenizePattern('My name is {0}'); // [{type: 'text', value: 'My name is '}, {type: 'placeHolder', value: 0}]
Get an optimized function for rendering a specific pattern. The function accepts the placeholder values as arguments.
Example:
inter.getPatternRenderer('My name is {0}')('George'); // 'My name is George'
Helper function for parse a date format into text and field tokens. The locale library must be built with the --dateformats switch.

Get one of the locale's standard full/long/medium/short time or date
formats, or a locale-specific format specified by a CLDR
