DZone Snippets: truncate code

truncate Rails development/test logs

laurelfan (Laurel Fan) — Tue, 07 Aug 2007 17:17:16 GMT

In rails applications development.log and test.log like to grow forever, which takes up space and makes them slow to grep. If I just delete them running processes with logs open might get confused. So I can use truncate instead:



truncate ~/www/*/log/*.log

Even easier, ask cron to do it for me every night:



4 22 * * * * truncate -s 0k  ~/www/*/log/*.log

  def truncate_words(text, length = 30, end_string = ' …')

    words = text.split()

    words[0..(length-1)].join(' ') + (words.length > length ? end_string : '')

  end

This will take a phrase and truncate it at the word level





function trunc($phrase, $max_words)

{

   $phrase_array = explode(' ',$phrase);

   if(count($phrase_array) > $max_words && $max_words > 0)

      $phrase = implode(' ',array_slice($phrase_array, 0, $max_words)).'...'  

   return $phrase;

}
