Backbone i18n with CoffeeScript
# before this file is loaded, a locale should be set:
#
# In a browser environment, you can use:
# ```<script>__locale='en';</script>```
#
# In a server environment (specifically node.js):
# ```global.__locale = 'en';```
# normalize in-app locale string to "en" or "de-AT"
parts = @__locale.split('-')
@__locale = parts[0].toLowerCase()
@__locale += "-#{parts[1].toUpperCase()}" if parts.length > 1
# define a global i18n object
# the `l` method returns a specific translation string or object
@i18n =
l: (id) ->
i18n[__locale]?[id] or i18n[__locale[0..1]]?[id] or i18n.en?[id]
# main translation method, assumes translation string is a
# Underscore.js template
@t = (id, vars = {}) ->
template = i18n[__locale]?[id] or i18n[__locale[0..1]]?[id]
unless template?
template = i18n.en?[id] or "(?) #{id}"
console.log("missing [#{__locale}] #{id}") if console?.log?
_.template(template, vars)
# i18n.de = # set to language, e.g. "i18n.en" or "i18n['en-US']"
# "hello": "Hallo"
# "X messages": "<%= count %> Nachrichten"
#
# __locale = 'de';
# t 'hello' # "Hallo"
# t 'X messages', count: 5 # "5 Nachrichten"
