# RenderingEngine

## Installation

Add this line to your application's Gemfile:

    gem 'rendering_engine'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install rendering_engine

## Usage

    $ content_provider = RenderingEngine::Provider.new(base_path)
    $ content = content_provider.get(relative_file_path)
    $ content.source #gets source of file (rendered or not :D)
    $ content.kind return (:orginal, :template, :unknown)

    In controller can looks like this:

    ---
    def show
      path = "#{params[:client]}/#{params[:path]}"
      data = params[:data]

      content = content_provider.get(path, data)
      return not_found if content.unknown?

      render text: content.source
    end

    def content_provider
      @content_provider ||= RenderingEngine::Provider.new(Rails.root.join('app/content'))
    end
    ---

## Own Helper class

```

class ContentCustomHelpers
  def initialize(opts={})
    @base_path = opts.fetch(:base_path)
    @data      = opts[:data]
  end

  def make_some_stuff
    "best line ever!"
  end

  def render(file_relative_path)
    file_path = File.join(base_path, file_relative_path)

    RenderingEngine::Content.new(file_path, data: data, custom_helper: self.class).source
  end

  attr_reader :data

  private

  attr_reader :base_path
end
