Module: Coradoc::Visitor

Defined in:
lib/coradoc/visitor.rb

Overview

Document visitor pattern for traversing and processing document trees.

The visitor pattern enables clean separation of document traversal logic from processing logic. Visitors can be used for:

  • Document transformation

  • Content extraction

  • Validation

  • Custom rendering

Examples:

Basic visitor

class WordCounter < Coradoc::Visitor::Base
  attr_reader :count

  def initialize
    @count = 0
  end

  def visit_block(block)
    @count += block.content.to_s.split.length if block.content
    super
  end
end

counter = WordCounter.new
document.accept(counter)
puts counter.count
