Rake task to grep out colors from a set of CSS stylesheets and display them on a web page. Default configuration works for OS X Safari and a Rails application.



BROWSER = "/Applications/Safari.app/Contents/MacOS/Safari"

CSS_FILES = "#{RAILS_ROOT}/public/stylesheets/**/*.css"



task :colors do

  require "tempfile"

  colors = Dir[CSS_FILES].map(&File.method(:read)).join.scan(/\#[0-9a-f]{3,6}/i).map{|c| c.upcase}.uniq

  Tempfile.open "colors" do |f|

    f.write <<-EOHTML

    

      

        

      

      

        #{colors.map{|clr| 

          " 
 #{clr} 
"

        }.join}

      

    

    EOHTML

    system BROWSER, f.path

  end

end

This code will provide 8 colors for cells and set of 8 lighter colors for alternating rows.



$sql  = 'SELECT * FROM `table` WHERE `column` = \'something\'';

$qry = mysql_query($sql) or die(mysql_error());



// Cell colors for odd rows

$c1  = array('#00CCCC', '#33CC00', '#CC0000', '#CCCC00', '#0000CC', '#FF6600', '#CC00CC', '#00CC99');



// Cell Colors for even rows

$c2  = array('#66FFFF', '#66FF00', '#FF3300', '#FFFF33', '#0033FF', '#FF9933', '#FF33CC', '#00FF99');



// Row Counter

$cnt  = 0;



$ret = '';

while($row = mysql_fetch_assoc($qry))

{

  // Cell counter

  $cnt2 = 0;

  $ret  .= '';

  foreach($row as $key=>$val)

   {

    $ret .= '';

    ++$cnt2;

   }

  ++$cnt;

  $ret .= ''."\n";

}

$ret .= ''.$val.'';



echo $ret;

?>
