Quickly tag event images to send to friends on Mac OS X Raw

tag.rb

#! /usr/bin/env ruby

# 20-minute hack to share a bunch of images
# taken an event with multiple people.
# Running this program will create thumbnails
# for each image. And then each thumbnail will
# be shown in Preview and you'll be asked to enter
# tags/names (seperated by spaces) for each one.
# Each original photo will be saved in tags/<tag-name>
# directory.

# Pre-processing:
# Create thumbnails for each image so that launching it
# would be quicker. Run this in bash.
# for img in *.jpg; do t=$(basename $img); echo $img; cp $img ${t%.*}_thumb.jpg; sips -Z 640 ${t%.*}_thumb.jpg; done

`mkdir -p tags; mkdir -p processed`
Dir['album_dir/*_thumb.jpg'].each do |thumbnail|
  original = thumbnail.gsub /_thumb/, ""
  original_base = File.basename original
  puts original
  if File.exists?("processed/#{original_base}")
    puts "skipping..."
    next
  end
  `touch processed/#{original_base}`
  `open #{thumbnail}`
  print "#{Time.now} tags > "
  $stdout.flush
  input = gets
  if input.nil?
    break
  elsif input == "\n"
    input = "general"
  end
  tags = input.split
  tags.each do |t|
    `mkdir -p tags/#{t}`
    next_count = Dir["tags/#{t}/*"].size + 1
    p Dir['tags/#{t}/*']
    puts " size of #{t}: #{next_count}"
    `cp #{original} tags/#{t}/#{next_count}.jpg`
  end
