Converts a dynamic rails (could be any site really) site into static files and rsyncs them up to the server

publish_static_site.rb

#!/usr/bin/env ruby

require 'fileutils'
require 'net/http'

URL = 'http://localhost:3000'
OUT_DIR = 'static_output'
SSH_PORT = 2222
SSH_URL = 'your_user@www.your_server.com:/your_folder/on_server/'

resp = Net::HTTP.get_response URI.parse(URL) rescue puts 'Error connecting' 
unless resp && resp.code == '200'
  puts "App not running (make sure to run rails under deploy: rails server -e deploy)"
  puts "Turn off asset tags in deploy env: ENV['RAILS_ASSET_ID'] = ''"
  exit 0
end

Dir.mkdir(OUT_DIR) unless File.exist?(OUT_DIR)
Dir.chdir(OUT_DIR) do
  puts `rm -R *`

  # Copy public, most of this will come over in the wget, but not all
  puts `cp -Rpv ../public/ .`
  
  `wget -m -x -p --no-host-directories --no-cache -erobots=off #{URL}`

  # Hack! I need files without extentions to still work on the server (they won't without
  # help).  There are 2 ways to do this that I thought of, they are below.
  #
  # It would be great if I could get wget to append all html files without an html extention 
  # to something like .foo so I can identify them. 
  # I guess I could parse the file for html or xml, I'll do that later
  Dir.glob("**/*").reject{|o| File.directory?(o)}.reject{|o| o =~ /.+\..+/}.each do |f|
    # There are 2 ways to do this, the best way is to mod nginx to turn any
    # url without an extention into one with .html (silently).  I'm going to use that 
    # approach. Here is an example config for nginx (note that try_files is the trick):
    #
    # location / {
    #   root   /your_server_files/public;
    #   index  index.html;
    #   try_files $uri $uri.html $uri/ @notfound;
    # }
    # location @notfound {
    #   return 404;
    # }
    #
    puts "Changing #{f} to #{f}.html"
    FileUtils.move(f,"#{f}.html")

    # This is a nother approach, creating a folder with the same name an sticking
    # the file inside it, renaming it to index.html.  This is less good
    #
    #puts "Changing #{f} to index.html in new #{f} folder"
    #FileUtils.move(f,"#{f}.temp")
    #Dir.mkdir(f)
    #FileUtils.move("#{f}.temp", "#{f}/index.html")
  end
  
  puts 'Rsyncing to server'
  puts `rsync -rv --stats --delete --exclude=.* -e "ssh -p #{SSH_PORT}" . #{SSH_URL}`
end

puts "\n\nAll finished"
