🔍 Pattern-Based Traversal with Pathname and Dir.glob

Combine Pathname with Dir.glob for clean, object‑oriented file discovery. This lets you apply patterns, filter results, and chain methods on Pathname instances for more readable directory management.

require 'pathname'

base = Pathname.new('app/models')
# Find all Ruby files in nested directories
ruby_files = Dir.glob(base.join('**', '*.rb'))
              .map { |f| Pathname.new(f) }

ruby_files.each do |file|
  puts "Model: #{file.basename('.rb')}"
end

You can further filter by file size or modification time:

large_files = ruby_files.select { |pn| pn.size > 10 * 1024 }
puts "Large model files:"
large_files.each { |pn| puts "– #{pn}" }
