    (?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*\\p{Punct})\\p{Graph}{8}
}}}
    

Example:

{{{class="brush: java; toolbar: false;"
    import java.sql.SQLException;
    import java.util.regex.Pattern;
    import java.util.regex.Matcher;

    public class reg {

        /**
        * @param args
        * @throws SQLException
        * @throws ClassNotFoundException
        */
        public static void main(String[] args) throws SQLException, ClassNotFoundException {
          Pattern p = Pattern.compile("(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*\\p{Punct})\\p{Graph}{8}");
          Matcher m = p.matcher("13a!56A2");
          boolean b = m.matches();
          System.out.println(b)
        }
    }
}}}

==Delete foo==

lösche jede Zeile, welche eine Fileendung enhällt
{{{class="brush: bash; toolbar: false;"
    (.*?)\.(.*)$
}}}

das gleiche nur im Vim
{{{class="brush: bash; toolbar: false;"
    :g/\.\(.*\)$/d
}}}
