irc.blah

[Oyarsa]

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?

[JanisB]

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

Code: Select all

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 :)

[Jason]

.+ 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.

[JanisB]

These are other features I'm planning to implement real soon now:
(?!pattern) Zero-width negative look-ahead assertions.

Oops, really... Sorry :<
