[Phplib-users] comments in template file

[Sven <Sv...@Ko...>]

Hello

Give it an easy way to delete comments in a template file so that the output 
not have the comments?
I will not use the HTML-method (<!-- ... -->) for commenting my template 
files.

My idea is a comment beginn with '{*' and end with '*}' or so.
The first idea was to make an owe function in template.inc to filter that 
comments. But i hope it give an easy way as an own function.


PS: I working with a cvs version of phplib.
PPS: Ich nehme auch gern Antworten als PM auf deutsch entgegen.

I need it now and have make this:

In template.inc at the end a new function:

 
/******************************************************************************
  * This function strip comments from templates.
  *
  * Returns: 
  *
  * @param     $str
  * @access    public
  * @return    string
  */
  function delete_comment($str) {
    if ($this->debug & 1) {
      print("<b>Varname:</b> $str<br>\n");
    }
    
    $left_delimiter = '{*';
    $right_delimiter = '*}';

    // Quote regular expression characters
    $ldq = preg_quote($left_delimiter, '!');
    $rdq = preg_quote($right_delimiter, '!');

    $str = preg_replace("!$ldq(.*?)$rdq!se", "", $str);
    
    return $str;
  }


Its not the best, but it works.

And i have write it in the finish function:


  function finish($str) {
    switch ($this->unknowns) {
      case "keep":
        $str = $this->delete_comment($str);
      break;

      case "remove":
        $str = preg_replace('/{[^ \t\r\n}]+}/', "", $str);
        $str = $this->delete_comment($str);
      break;

      case "comment":
        $str = preg_replace('/{([^ \t\r\n}]+)}/', "<!-- Template variable \\1 
undefined -->", $str);
        $str = $this->delete_comment($str);
      break;
    }

    return $str;
  }



Better ideas are welcome (-;

Hello

In my old function i can't delete comments inside comments.
For example:
{* comment A {* comment B *} *}

With this function, we can kill all comments:

  /**********************************************************
  * This function strip comments from templates.
  *
  * Returns:
  *
  * @param     $str
  * @access    public
  * @return    string
  */
  function delete_comment($str) {
    $a = 1;
    $b = 0;
    while ($a > $b) {
      $a = strlen($str);
      $str = preg_replace('/(\{\*(?:[^{*]|\{(?!\*)|\*(?!\}))*\*\})/', '', 
$str);
      $b = strlen($str);
    }
    return $str;
  }
