module GetText
# This module provides basic functions to evaluate plural ERB files(.rhtml) in a TextDomain.
# You need to implement a class which includes GetText::ErbContainer.
#
# See simple examples below:
#
# require 'gettext/erb'
# class SimpleContainer
# include GetText::ErbContainer
#
# def initialize(domainname, domainpath = nil, locale = nil, charset = nil)
# bindtextdomain(domainname, domainpath, locale)
# end
# end
#
# container = SimpleContainer.new("helloerb1", "locale")
# puts container.eval_file("/your/erb/file.rhtml")
#
# This module is an example for template engines such as ERB.
# You can implement another implementation easily to read gettext/erb.rb.
module ErbContainer
include Container
# Evaluates ERB source(String) in the instance and returns the result HTML.
#
# * rhtml: an ERB source
# * Returns: the Evaluated ERB result
def eval_src(rhtml)
erb = ERB.new(rhtml).src
eval(erb, binding)
end
# Evaluates ERB file in the instance and returns the result HTML.
#
# * rhtml: an ERB file
# * Returns: the Evaluated ERB result
def eval_file(rhtmlpath)
eval_src(IO.read(rhtmlpath))
end
