Notare

A Ruby gem for creating docx files with a simple DSL

Installation

Add this line to your application's Gemfile:

gem 'notare'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install notare

Usage

Basic Example

require 'notare'

Notare::Document.create("output.docx") do |doc|
  doc.p "Hello World"
end

Paragraphs

Notare::Document.create("output.docx") do |doc|
  # Simple paragraph
  doc.p "This is a paragraph."

  # Paragraph with multiple text runs
  doc.p do
    doc.text "First part. "
    doc.text "Second part."
  end
end

Text Formatting

Formatting uses nested blocks. Nesting combines formatting styles.

Notare::Document.create("output.docx") do |doc|
  doc.p do
    doc.text "Normal text "
    doc.b { doc.text "bold" }
    doc.text " and "
    doc.i { doc.text "italic" }
    doc.text " and "
    doc.u { doc.text "underlined" }
  end

  # Nested formatting (bold + italic)
  doc.p do
    doc.b do
      doc.i { doc.text "bold and italic" }
    end
  end
end

Headings

Use h1 through h6 for document headings:

Notare::Document.create("output.docx") do |doc|
  doc.h1 "Document Title"
  doc.h2 "Chapter 1"
  doc.h3 "Section 1.1"
  doc.h4 "Subsection"
  doc.h5 "Minor heading"
  doc.h6 "Smallest heading"

  # Headings with formatted content
  doc.h2 do
    doc.text "Chapter with "
    doc.i { doc.text "emphasis" }
  end
end
