Caracal-Rails

Caracal is a ruby library for dynamically creating professional-quality Microsoft Word documents.

Caracal-Rails is a drop in solution for registering the Microsoft Word mime type and for establishing a template handler in Rails for the :docx format. All caracal documents are rendered with an explicit block passing a reference to the Caracal::Document object named docx.

Please see the caracal-example repository for a working demonstration of the library's capabilities.

Installation

Add this line to your application's Gemfile:

gem 'caracal-rails'

Then execute:

$ bundle install

Usage

Design your controller normally:

class ReportsController < ApplicationController
  def show
    # collect your models/view models here
  end
end

Then add a view file with the Caracal extension:

apps/views/reports/show.docx.caracal

Inside your view, simply issue Caracal commands on the document object:

docx.font 'Droid Serif'

docx.style 'special' do
  font   'Droid Serif'
  italic true
  size   16
end

docx.h1 'Quarterly Report'
docx.hr
@report.clients.each do |client|
  docx.h2 client.name
  docx.p  'Lorem ipsum dolor...'
  docx.p do
    text 'This is a sentence with a '
    link 'link', 'http://www.google.com/', style: 'special'
    text ' in the middle.'
  end
  docx.img image_url('https://www.example.com/logo.png'), width: 300, height: 200, align: 'right'
  docx.br
  docx.table client.tablular_data, border_size: 4 do
    cell_style  rows[0], background_color: '3366cc', color: 'ffffff', bold: true
  end
  docx.page
  docx.p 'This is an bulleted list.'
  docx.ul do
    li do
      strong 'Item 1'
      text   'More text'
    end
    li 'Item 2'
  end
end
