i18n-inflector-rails version 1.0 (Rain)
This Rails plug-in contains bindings for the I18n Inflector module for Ruby’s I18n. It overwrites the translate() method from Rails in a way that it will interpolate additional inflection tokens present in translations. These tokens may appear in patterns which are contained within @{ and } symbols.
It’s intended to be used in a projects where tranlations are performed by many people, yet there is a need to inflect sentences or words by user’s gender, person or other data.
To achieve similar functionality lambdas can be used but including Proc objects in translations may be considered unsafe.
If you have a troop of happy translators that shouldn’t have the ability to execute any code yet you need some simple inflection then this plug-in might help you.
translate('.welcome')
en:
welcome: "Dear @{f:Lady|m:Sir|n:You|All}"
en:
i18n:
inflections:
gender:
f: "female"
m: "male"
n: "neuter"
female: @f
male: @m
neuter: @n
man: @male
woman: @female
default: n
class ApplicationController < ActionController::Base inflection_method :gender # assuming that @gender is set somewhere def gender @gender || nil end end class UsersController < ApplicationController # t() will call method gender() from the current context # to get the inflection token def say_welcome t('welcome') # => "Dear Sir" end end
You can create your own kinds (gender, title, person, time, author, etc.) of tokens to group them in a meaningful, semantical sets.
This plug-in adds {I18n::Inflector::Rails::ClassMethods#inflection_method inflection_method}, {I18n::Inflector::Rails::ClassMethods#no_inflection_method no_inflection_method} and {I18n::Inflector::Rails::ClassMethods#no_inflection_method_for no_inflection_method_for} clauses that can be used in controllers and views. Using that clauses makes it easy to register methods that will be called to obtain certain inflection options. It is also possible to set up an inflection method for a so called strict kind commonly used in a so called named and complex patterns.
This plug-in uses i18n-inflector module which allows passing inflection options to the translate method. You may find I18n Inflector’s API and a default object very helpful since they allow you to read inflection data in many different ways. You might, for example, use it to generate forms containing lists of languages that are using inflection, or to view all known inflection kinds or tokens assigned to them.
To access the Inflector object bound to default I18n backend use:
I18n.inflector
The previous example is not compatible with Psych parser, which is used by Rails 3. There are two ways to solve that problem.
First is to change a YAML file and replace any value that has special meaning with a symbol:
en:
i18n:
inflections:
gender:
f: "female"
m: "male"
n: "neuter"
female: :@f
male: :@m
neuter: :@n
man: :@male
woman: :@female
default: :n
Second way is to use other parser by adding to config/boot.rb:
require 'yaml' YAML::ENGINE.yamler = 'syck'
-
git clone git://github.com/siefca/i18n-inflector-rails.git
-
gem install i18n-inflector-rails
You can run RSpec examples both with
-
rake specor justrake -
run a test file directly, e.g.
ruby -Ilib -Ispec spec/inflector_spec.rb
See {I18n::Inflector::Rails::ClassMethods} to learn how to use inflection_method and no_inflection_method.
See {I18n::Inflector::Rails::InflectedTranslate} to learn about using the translation wrapper.
See {I18n::Inflector::InflectionOptions} to know more about switches that can be used to control the engine.
See the whole documentation for more information.
To know how the basics and to learn more about Inflector that is used by this plug-in see I18n Inflector documentation.
