[cl-irc-devel] [patch] Make cl-irc more compatible with bouncers
by Andreas Fuchs 27 Jan '06

27 Jan '06

Hi, irc bouncers like miau send a 30-minute backlog on reconnect. The problem is that they don't send NAMES before they send the backlog. AFAICT, that's even allowed by the irc spec. cl-irc breaks when it sees a QUIT message when it didn't build a channel user table before. This patch makes cl-irc accept quit messages when it can't find a user for them: Cheers, -- Andreas Fuchs, (http://|im:asf@|mailto:asf@)boinkor.net, antifuchs

[cl-irc-devel] [patch] Add a connection arg to irc-message-event
by Andreas Fuchs 27 Jan '06

27 Jan '06

Hi, Beirc as it is right now uses a really ugly re-implementation of the read-message method, because in order to operate correctly, we can't just use an :around method on read-message like this: (defmethod read-message ((con my-irc-connection)) (let ((m (call-next-method))) (dispatch-on-message m) m)) Why? Because (in the case of a QUIT message) read-message modified the channel user table already when beirc tries to find out which channels a user who just quit was on. So, I think we're specializing a method one level too high. We should be specializing the irc-message-event method, but it has no connection argument. Yet. The attached patch adds a connection argument on which irc-message-event can be specialized. I would also suggest exporting irc-message-event and making that method the recommended way to dispatch on all messages on an irc connection. I've used this patch with a locally hacked version of beirc for a few days now and it works very well for me. I hope you all like it, because I'd really like to see that ugly wart in beirc go away.

[cl-irc-devel] Start using trivial-sockets to reduce implementation dependent code
by Erik Huelsmann 24 Jan '06

24 Jan '06

Hi! Somewhere in the TODO, there's mention of abstracting/extracting implementation dependent sockets code into it's own (simple) library. I believe that library has been available for a while now and would like to switch cl-irc to using that: trivial-sockets. Hoping for reactions (but committing the change otherwise), Erik. -- Telefonieren Sie schon oder sparen Sie noch? NEU: GMX Phone_Flat http://www.gmx.net/de/go/telefonie

[cl-irc-devel] Switching CVS to Subversion?
by Erik Huelsmann 23 Jan '06

23 Jan '06

Hi! Well, it's no secret that I am a Subversion dev, but apart from that: I like Subversion's interface (much) better than CVS's. Is there anybody who objects to switching the CVS repository to Subversion? bye, Erik. -- 10 GB Mailbox, 100 FreeSMS/Monat http://www.gmx.net/de/go/topmail +++ GMX - die erste Adresse f�r Mail, Message, More +++

[cl-irc-devel] [PATCH] Add 'seen' and 'spoke' support
by Erik Huelsmann 06 Jan '06

06 Jan '06

Hi! Some time ago Xach (Zach) gave me the source to a utility routine he wrote to add 'seen' tracking to a bot of his. I generalised the code and made library-code of it adding several hooks. The patch below applies to HEAD as of this moment and adds a generalised version of event tracking. It does not only track 'seen', it adds 'spoke' by default too. Next to that, it implements the general tools to track any event a library-user may want to track. I'd *love* to hear your comments. bye, Erik.
