Hello Pinku. Are you using the irc.client vocab? I have been (slowly) working on a rewrite, because it is too complex. In case you want to look at it, I have pushed the new irc client vocab (irc.client2) to the irc-new branch of my repository: git://tiodante.com/git/factor.git irc-new I haven't asked slava to merge it yet because I was writting a new logger bot and logger viewer, and the api could change a bit (but I don't think it is going to change much, so if you want to use it, you are safe). Another important reason for not asking slava to merge it is that I haven't documented it yet :) Anyway, check it if you think it could be useful. -- bd ------------------------------------------------------------------------------ Come build with us!
