require 'rubygems'
require 'bundler/setup'

require 'rack'
require 'rack-rewrite'
require 'rack-legacy'

public_dir = File.join(Dir.getwd, 'public')

use Rack::Rewrite do
    rewrite %r{(.*)?}, lambda {|match, rack_env|
        if rack_env['PATH_INFO'].include?('assets') or File.exists?(File.join(public_dir, match[1]))
            return match[1]
        else
            "/index.php" + match[1]
        end
    }
end

use Rack::Legacy::Php, File.join(public_dir)
run Rack::File.new File.join(public_dir)
