    <p>first question here.</p> <p>So for a club at school we are working on making a IRC client in Python and Twisted.</p> <p>So I take the example bot that twisted gives you. I've managed to get it connected to a irc channel, and it logs.</p> <p>I know I've probably gotta use 2 threads to have both reading from the server and input simultaneous, which I can achieve, but only if it command line input. Mind you it is still logging the data from the channel at the same time.</p> <p>So to do this I used: <code>d = threads.deferToThread(aSillyBlockingMethod)</code></p> <p>Which calls my <code>raw_input()</code> loop.</p> <p>My problem lies in not being able to figure out how to change this from just typing into and printing form the commandline; to being able to actually send messages to the irc server for other people to read.</p> <p>Any help would be greatly appreciated. I am a novice python programmer and don't know too much web stuff; like protocols, ports, and stuff like that but I am slowly picking them up. If anyone knows of an easier way to do this let me know please I am not committed to using Twisted.</p> <p>Here is my code, or rather the modified bot I'm tinkering with:</p> <pre><code># twisted imports from twisted.words.protocols import irc from twisted.internet import reactor, protocol from twisted.python import log from twisted.internet import threads # system imports import time, sys class MessageLogger: """ An independent logger class (because separation of application and protocol logic is a good thing). """ def __init__(self, file): self.file = file def log(self, message): """Write a message to the file.""" timestamp = time.strftime("[%H:%M:%S]", time.localtime(time.time())) self.file.write('%s %s\n' % (timestamp, message)) self.file.flush() def close(self): self.file.close() class LogBot(irc.IRCClient): """A logging IRC bot.""" nickname = "twistedbot" def connectionMade(self): irc.IRCClient.connectionMade(self) self.logger = MessageLogger(open(self.factory.filename, "a")) self.logger.log("[connected at %s]" % time.asctime(time.localtime(time.time()))) def connectionLost(self, reason): irc.IRCClient.connectionLost(self, reason) self.logger.log("[disconnected at %s]" % time.asctime(time.localtime(time.time()))) self.logger.close() # callbacks for events def signedOn(self): """Called when bot has succesfully signed on to server.""" self.join(self.factory.channel) def joined(self, channel): """This will get called when the bot joins the channel.""" self.logger.log("[I have joined %s]" % channel) def privmsg(self, user, channel, msg): """This will get called when the bot receives a message.""" user = user.split('!', 1)[0] self.logger.log("&lt;%s&gt; %s" % (user, msg)) # Check to see if they're sending me a private message if channel == self.nickname: msg = "It isn't nice to whisper! Play nice with the group." self.msg(user, msg) return # Otherwise check to see if it is a message directed at me if msg.startswith(self.nickname + ":"): msg = "%s: I am a log bot" % user self.msg(channel, msg) self.logger.log("&lt;%s&gt; %s" % (self.nickname, msg)) def action(self, user, channel, msg): """This will get called when the bot sees someone do an action.""" user = user.split('!', 1)[0] self.logger.log("* %s %s" % (user, msg)) # irc callbacks def irc_NICK(self, prefix, params): """Called when an IRC user changes their nickname.""" old_nick = prefix.split('!')[0] new_nick = params[0] self.logger.log("%s is now known as %s" % (old_nick, new_nick)) # For fun, override the method that determines how a nickname is changed on # collisions. The default method appends an underscore. def alterCollidedNick(self, nickname): """ Generate an altered version of a nickname that caused a collision in an effort to create an unused related name for subsequent registration. """ return nickname + '^' def aSillyBlockingMethod(self): import time while True: msg = raw_input() print msg class LogBotFactory(protocol.ClientFactory): """A factory for LogBots. A new protocol instance will be created each time we connect to the server. """ def __init__(self, channel, filename): self.channel = channel self.filename = filename def buildProtocol(self, addr): p = LogBot() p.factory = self return p def clientConnectionLost(self, connector, reason): """If we get disconnected, reconnect to server.""" connector.connect() def clientConnectionFailed(self, connector, reason): print "connection failed:", reason reactor.stop() if __name__ == '__main__': # initialize logging log.startLogging(sys.stdout) # create factory protocol and application f = LogBotFactory("#goon.squad.dev", "test.txt") # connect factory to this host and port reactor.connectTCP("irc.freenode.net", 6667, f) #Use this to keep user input open d = threads.deferToThread(aSillyBlockingMethod) # run bot reactor.run() </code></pre> <p>--TyrZaraki</p>

    1. COTo clarify - you want `aSillyBlockingMethod` to translate the `raw_input` into actually sending a message?

    2. COYeah that method should be named something like send_msg, but ultimately yes I need a method that can be used in a second thread to send messages to the irc server.

    3. COYou'll have to excuse me - I haven't messed around with Twisted in a while. However, my understanding is that it's an event framework, and the simplest way to handle this would be to allow Twisted to handle the user IO.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
