Wikka: Wikka-markup in Comments

Wikka-markup in Comments

Working for 1.1.6.0 to 1.1.6.4 (latest)

To make comments a little bit more flexible, why don't add a part of wikkas markup?

I thought about: italic, bold, monospace, strikethough, underlined, notes, WikiWords and InterWikiLinks

1. Problem

There is no backwards compatibility to older comments now because of the following problem:
Since a formatter for comments does not exist, "handlers/page/addcomment.php", uses nl2br to store the html in the table itself. So older commenst will show up "<br />" at the end of every line.

If you have a wiki without older comments, everything will work fine.

The Code

0. In handlers/page/addcomments.php change the line:

$body = nl2br($this->htmlspecialchars_ent(trim($_POST["body"])));

into the following one:

$body = $this->htmlspecialchars_ent(trim($_POST["body"]));

Remaining problem: the <br /> in the already existing comments remain, and will show up now (see above).

1. Search in handlers/page/show.php for display comments themselves:

There you can find these lines:

echo '<div class="comment">'."\n".
'<span id="comment_'.$comment['id'].'"></span>'.$comment['comment']."\n".
"\t".'<div class="commentinfo">'."\n-- ";
echo ($this->LoadUser($comment['user']))? $this->Format($comment['user']) : $comment['user']; // #84

change these statements into these ones!

echo '<div class="comment">'."\n".
'<span id="comment_'.$comment['id'].'"></span>'.$this->Format($comment['comment'], 'comments')."\n".
"\t".'<div class="commentinfo">'."\n-- ";
echo ($this->LoadUser($comment['user']))? $this->Format($comment['user'],'comments') : $comment['user']; // #84

2. Save the following as formatters/comments.php:

<?php

// This may look a bit strange, but all possible formatting tags have to be in a single regular expression for this to work correctly. Yup!

//#dotmg [many lines] : Unclosed tags fix! For more info, m.randimbisoa@dotmg.net ((only indents? --NilsLindenberg))
if (!function_exists("comments2callback"))
{
function comments2callback($things)
{
$thing = $things[1];
$result='';

static $trigger_bold = 0;
static $trigger_italic = 0;
static $trigger_underline = 0;
static $trigger_monospace = 0;

if ($trigger_monospace % 2) echo('</tt>');
if ($trigger_notes % 2) echo ('</span>');
if ($trigger_strike % 2) echo ('</span>');
if ($trigger_sup % 2) echo '</sup>';
if ($trigger_sub % 2) echo '</sub>';

$trigger_bold = $trigger_italic = $trigger_underline = $trigger_monospace = $trigger_notes = $trigger_strike = $trigger_sup = $trigger_sub = 0;
return;
}

// convert HTML thingies
if ($thing == "<") return "<";

// bold

}
*/

// interwiki links!

{
return $wakka->Link($thing);
}

// wiki links!
else if (preg_match("/^[A-ZÄÖÜ]+[a-zßäöü]+[A-Z0-9ÄÖÜ][A-Za-z0-9ÄÖÜßäöü]*$/s", $thing))
{
return $wakka->Link($thing);
}

// new lines
else if ($thing == "\n")
{
$result .= ($br ? "<br />\n" : "\n");
$br = 1;
return $result;
}

// if we reach this point, it must have been an accident.
return $thing;
}
}

$text = str_replace("\r\n", "\n", $text);

// replacing part of urls so the don't get italic
$text = preg_replace('#://#', "DUMPTEXT", $text);

$text = preg_replace_callback(

// we're cutting the last <br />
$text = preg_replace("/<br \/>$/","", $text);

// re-replacing the url-part
$text = ereg_replace("DUMPTEXT", "://", $text);

// $text = $this->Typography($text); // only needed for SmartyPants in comments (see there)
echo ($text);
comments2callback('closetags');
?>

Configurable comment markup

1. Add the following line to wikka.config.php:

"markup_comments" => "1",

where '1' means to allow markup and '0' means to disallow it.

2. In handlers/page/addcomments.php change the line:

$body = nl2br($this->htmlspecialchars_ent(trim($_POST["body"])));

into the following statement:

if (($this->GetConfigValue('markup_comments') == 1) && file_exists('formatters/comments.php'))
{
$body = $this->htmlspecialchars_ent(trim($_POST["body"]));
}
else {
$body = nl2br($this->htmlspecialchars_ent(trim($_POST["body"])));
}

3. Search in handlers/page/show.php for display comments themselves:

There you can find these lines:

change these statements into these ones!

if (($this->GetConfigValue('markup_comments') == 1) && file_exists('formatters/comments.php'))
{
echo '<div class="comment">'."\n".
'<span id="comment_'.$comment['id'].'"></span>'.$this->Format($comment['comment'], 'comments')."\n".
"\t".'<div class="commentinfo">'."\n-- ";
echo ($this->LoadUser($comment['user']))? $this->Format($comment['user'],'comments') : $comment['user']; // #84
}
else {
echo '<div class="comment">'."\n".
'<span id="comment_'.$comment['id'].'"></span>'.$comment['comment']."\n".
"\t".'<div class="commentinfo">'."\n-- ";
echo ($this->LoadUser($comment['user']))? $this->Format($comment['user']) : $comment['user']; // #84
}

3. Use the comments.php from above.
