Description

Since the first day Lampoon#jquery couldn't tell what the user said last time. All of a sudden sometimes it would work.

After debugging today, it turned out that bot_seen_all_nicks_for_regexp() was quoting symbols in nicks for regex before separating out the first letter of the nick.

So for some nicks it turned out to be like:

<?php
/**
* Return an array of all current nicks.
*/
function bot_seen_all_nicks_for_regexp() {
  ...
     
$nick_name = preg_quote($nick_name, '/');
     
$nick_name = preg_replace('/^(.)(.*)/', '(\1)(\2)', $nick_name);
     
$nicks[] = '/\b' . $nick_name . '\b/i';
  ...
}
?>

Converts [domon] int /\b(\)([domon\])\b/i rather than, /\b(\[)(domon\])\b/i. See the (\) becoming the block in the first example, which should rather contain escaped [.

The fix is just to reverse the quote and replace lines, so we first separate out the nicks, then quote to escape the chars:

<?php
/**
* Return an array of all current nicks.
*/
function bot_seen_all_nicks_for_regexp() {
  ...
     
$nick_name = preg_replace('/^(.)(.*)/', '(\1)(\2)', $nick_name);
     
$nick_name = preg_quote($nick_name, '/');
     
$nicks[] = '/\b' . $nick_name . '\b/i';
  ...
}
?>

critical, since the claimed feature won't work if users have such nicks in the room.

These were the users in #jquery few hours back: http://pastie.org/495069.txt (search for (\)).

Totally see the logic with all this, and agree the fix is sound.

Will get it in when I can.
