    One eye on the browser, one eye on the console

    Step 1. Drop this in lib/tasks/development.rake:

    task "server" do
  # Dump lines from the file to the console at the specified interval (in seconds).
  def tail(file_name, interval = 1)
    position = File.size(file_name)
    leftover = ""
    while true
      sleep interval
      File.open file_name do |file|
        file.seek position
        text = file.read
        lines = text[/([^n]*n)*/m]
        if lines.empty?
          leftover << text
        else
          puts (leftover + lines)
          leftover = text[lines.size..-1]
        end
        position = file.tell
      end
    end
  end

  pid = "#{RAILS_ROOT}/tmp/pids/mongrel.pid"

  trap "INT" do
    puts "Stopping mongrel"
    puts `mongrel_rails stop -P #{pid}`
    exit
  end

  puts "Starting mongrel, hit Ctrl-C to stop"
  puts `mongrel_rails start -d -e #{RAILS_ENV} -P #{pid}`
  tail "log/development.log"
end

    Step 2. Start the server:

    rake start

    Step 3. Hit the browser, watch the log, hit Ctrl-C to kill.

    Update: If you’re using Sake (if not, what’s taking you so long?), you can skip step 1 and install it once for all your apps:

    sake -i http://pastie.caboo.se/90791.txt

      You could also run this straight in bash:
      mongrel_rails start -d && tail -f log/development.log

      I’ve got that aliased as ’sslog’

      Thanks for showing us how to do tail in Rake though!

      It actually started from the same bash line, which I got tired of retyping, so I moved it into rake by making system calls, and then rewrote it to run on the UNIOS/X and that other GUI platform.

      Not only we are using Sake, but we used the RailsRumble to build a directory where people can submit, tag ans search sake snippets. Please feel free to take a look at it: http://sakebar.railsrumble.com/
