Localize

Localize is a small library for internationalization. Example:

puts t.hello # => Hola
puts t.hello.world # => Hola, mundo
puts t.hello('world', 'space') # => Hello world and space
puts f 380441234567 # => +380 (44) 123-45-67
puts l Time.utc(2000, "jan"), :short # => Sat 01-Jan-00
puts l 1200.05 # => 1.200,05

Install

gem install localize
gem install xml-simple  # if your localization file will be xml format
require 'localize'

Setup

Set the store, yaml or plain for now, xml and others planned (default yaml):

Localize.store = :plain

Specify location of the translation files:

Localize.location = 'lib/translations'

if store set to plain, location must be a ruby hash:

Localize.location = {'text' => { 'hello' => {'world' => 'mundo' } }

Set locale:

Localize.locale = :esp

and default locale (optional, en by default):

Localize.default_locale = :ru

Now, load the translation:

t = Localize.translate
f = Localize.f
l = Localize.l

Sinatra setup

sinatra.rb contains predefined helpers t, l and f and set locale from session['locale']

require 'localize/sinatra'
Localize.default_locale = :ru
Localize.location = 'locales' # Change to your path

Translation files

Translation file must contain two sections: ‘text’ and ‘formats’.

Text section contains translations and can have an unlimited nesting:

text:
  hello: 'hola' # t.hello
  foo:
      bar: 'baz' # t.foo.bar

You may interpolate you translations:

text:
  hello: 'Hello ${1} and ${2}!'
  foo: 'Foo ${2}, ${1} or ${1}, ${3}'

…in translation, and…

t.hello('world', 'space')
t.foo('bar', 'baz', 'fee')

…in view produce ‘Hello world and space!’ and ‘Foo baz, bar or bar, fee’

Formats section contains different localization rules and formats:

formats:
  phone:
    full: '+### (##) ###-##-##'
    short: '###-##-##'
  number:
    separator: ','
    dec_point: '.'

Phone subsection must have format named ‘full’, and may have arbitrary names which can called by second parameter in f method:

f(78977654) # Full format
f(12345678, :short)
f(32145687, :other)

Date subsection must contains translations for months and days of the week. Also set formats in strftime format:

formats:
  date:
    format:
      full: '%a %b %d %H:%M:%S %Z %Y'
      short: '%a %d-%B-%y'
