How easy would it be to implement Compile --watch support

[richtera]

I would like to use apache to serve up the files during development since I have some php pages to support oauth authentication which so far I have not been able to do with a purely static site. I guess I could do some proxy apache hackery to point to WebBrick, but it would be much better if deployment and development were working more similar anyways.

I'm in a similar situation. For now I work around it with a Rakefile task:

# Rakefile task to recompile ruhoh when a file changes.
# To use it:
# - add it to a Rakefile in your project's top level directory 
# - run ```rake watch``` in a separate tmux session.
#
# It ignores:
#  - whatever is in the top-level .gitignore
#  - SASS (that compiles in a different task and its output will force a recompile here)
#
# It has caveats:
# - add .watched to .gitignore!
# - This task uses unix shell commands and not pure Ruby (for now)
dir = File.dirname __FILE__

task :watch do
  desc "watches directory and compiles project if important files have changed."
  while true do
    cache = "#{dir}/.watched"

    files = %x{  ls -a1 #{dir} | egrep -v -f .gitignore | egrep -v '_scss' | grep -v ^\\\\. | xargs grep -rl . | xargs md5sum }
    if not File.exists? cache
      File.write( cache, files )
    else
      require 'tempfile'
      tmp = Tempfile.new( '.ruhoh.watched' )
      tmp.write( files )
      tmp.close
      diffs = %x{ diff #{cache} #{tmp.path} }
      if diffs.size > 1
        puts
        puts %x{ruhoh compile -v}
        puts

        # POST-COMPILE TASKS
        # ------------------
        # Add any post-compile fixes here (permission updates, extra files under compile/, etc)
        # I've commented mine out, but left them in as examples

        ## Include CSS for comments
        #puts %x{mv #{dir}/compiled/assets/stylesheets/comments*.css #{dir}/compiled/comments/comments.css}
        #puts
        #
        ## Fix permissions for apache 
        #puts %x{chown apache:apache #{dir}/compiled/comments/pages}
        #puts
        #
        ## Compile README.md to see how it will look when checked in
        # puts 'updating README'
        #puts %x{/usr/local/rvm/gems/ruby-1.9.3-p392/bin/redcarpet #{dir}/README.md > #{dir}/README.html}

        File.write( cache, files )
        puts
        print "watching #{dir}"
      else
        print "."
        $stdout.flush
      end
    end
    sleep 1
  end
end

Ahh, cool solution, thanks Andy
