[Plugin: WP-Syntax] dont works highlighting code in comments in 0.9.13

@flector

Sorry, I can not reproduce this. It must be the theme or another plugin preventing syntax highlighting in the comments.

I’m sorry for my English.
I try to describe.

By default “subscribers” cannot add code in comments.
I did little hack:

1. code in functions.php

function replace_code_pre ($matches){
    $out = str_replace( array('<','>'), array('<','>'), $matches[3] );
    return "<{$matches[1]}{$matches[2]}>".$out."</{$matches[1]}>";
}
function code_in_comments($comment_text){
    $comment_text = preg_replace_callback ('!<(pre|code)([^>]*)>(.*?)</\\1>!ims', 'replace_code_pre', $comment_text);
    return $comment_text;
}
add_filter ('pre_comment_content','code_in_comments');

remove_filter ('comment_text',  'wptexturize');

2. in wp-syntax.php after line 114 (in version 0.9.12)
$escaped = trim($match[3]);
add line:
$escaped = "true";

after this hack any subscribers can add code in comments. but in version 0.9.13 code is published, but without highlighting.

any suggestions? I really need posting code by subscribes.
thank you.

there are & lt; and & gt; in function replace_code_pre
$out = str_replace( array('<','>'), array('& lt;','& gt;'), $matches[3] );
without spaces.

Oh, ok, I see. Open the wp-syntax.php file and fine this code starting at line 37

/*if (!CUSTOM_TAGS) {
  $allowedposttags['pre'] = array(
    'lang' => array(),
    'line' => array(),
    'escaped' => array(),
    'style' => array(),
    'width' => array(),
	'highlight' => array(),
    'src' => array()
  );
  //Allow plugin use in comments
  $allowedtags['pre'] = array(
    'lang' => array(),
    'line' => array(),
    'escaped' => array(),
	'highlight' => array()
  );
}*/

And change it to:

if (!CUSTOM_TAGS) {
  $allowedposttags['pre'] = array(
    'lang' => array(),
    'line' => array(),
    'escaped' => array(),
    'style' => array(),
    'width' => array(),
	'highlight' => array(),
    'src' => array()
  );
  //Allow plugin use in comments
  $allowedtags['pre'] = array(
    'lang' => array(),
    'line' => array(),
    'escaped' => array(),
	'highlight' => array()
  );
}

The only change is uncommenting it. I didn’t test, but I think this should revert the change that made your hack work.

You might want to accomplish this a different way though. This blog post explains how to tap into a different filter to change the tags and attributes that are permitted rather than doing this string replace you’re doing.
