Ok just getting into the spamfilters.
These are very cool I must say
Anyway ... there is an example in the docs of:
/spamfilter add pc block - - come to irc\..+\..+
which is great but it also blocks my own irc net's name that way. How would I have it block all others save for my own?

Code: Select all
<?php
$r = '/come to irc\.(?!blah\.).+/';
echo preg_match($r, 'come to irc.blah.net').'<br>';
echo preg_match($r, 'come to irc.net').'<br>';
echo preg_match($r, 'come to irc.le-blah.net');
?>
will output

JanisB: UnrealIRCd uses the TRE, not PCRE, regular expressions engine.

According to
homepage and
syntax reference i found, that TRE knows, what (?!blah\.) is and how to match .+, so I think my example will work on Unreal. Sure, without beginning-end slashes :)

.+ and \., etc, are standard for all POSIX compliant regexes (and you're not really a regex if you don't understand them)
You're incorrect about the (?!blah\.) portion, however. It is in his todo list, not his features list.
