ircflu is an IRC bot written in Go with a flexible message- & command-handler. Among its advanced features are a cat-server which allows you to forward incoming messages from a TCP socket straight to an IRC channel, and an integrated HTTP server ready to process incoming JSON-API calls.
At Tomahawk (http://tomahawk-player.org) we're all pretty much addicted to IRC. We use it not only to coordinate our development efforts and communicate, but also to get alerted about source code changes on GitHub, when a ticket gets updated or a service on our servers runs into an issue. We can even use it to trigger commands being executed on our servers, e.g. to deploy the latest source code.
ircflu can do all that for us... except the communicating. It's not that kind of chatbot.
Make sure you have a working Go environment. See the install instructions.
First we need to get the required dependencies. ircflu itself is part of that list so the main executable can depend on our sub-packages:
go get -u github.com/muesli/ircflu
Now we can build ircflu:
git clone git://github.com/muesli/ircflu.git
cd ircflu
go build
To run the application you will need to specify at least a few parameters:
./ircflu -irchost="some.server:6667" -ircchannel="#ircflu"
You can control which commands you want to be enabled with the '-commands' option. Be aware that enabling the 'exec' command allows authenticated users to remotely execute arbitrary commands on your machine! To start ircflu with all currently available commands run:
./ircflu -commands="alias,auth,exec,join,part,send" -authpassword="some_password" -irchost="some.server:6667" -ircchannel="#ircflu"
Run ircflu -help to see a full list of options!
When started with its default options, ircflu will listen for incoming connections on TCP port 12345. You can now send messages to an IRC channel from your favorite shell script or a terminal:
echo "This will be sent to the default channel on IRC." | netcat -q0 127.0.0.1 12345
echo "#somechannel This will be sent to a specific channel on IRC." | netcat -q0 127.0.0.1 12345
echo "#* This will be sent to all joined IRC channels." | netcat -q0 127.0.0.1 12345
echo "@someuser This will be sent to a specific user on IRC." | netcat -q0 127.0.0.1 12345
It comes with a simplistic authentication system (!auth), supports aliases for commands (!alias) and executing external applications (!exec), forwarding their output to IRC.
To authenticate with ircflu, use the auth command in a private query with it:
!auth [your_auth_password]
Once you're authed, you can execute a command on ircflu's host:
!exec /usr/local/bin/some_executable
You can also make it join or part IRC channels:
!join #test
!part #test
Here's how you can create and use aliases:
!alias deploy = exec ssh myserver ~/deploy.sh
!deploy
ircflu also runs an integrated HTTP server on port 12346, processing incoming GitHub (on /github) & GitLab (on /gitlab) web-hook calls which are triggered by a commit to your git repository.
To connect GitHub with ircflu, go to your repository's settings page, click on 'Service Hooks' and then pick 'WebHook URLs' from the list. Add a new web-hook here, e.g.: 'http://your.ircflu.host:12346/github'
Whenever you push something to your repository now, ircflu will post a nice little summary of your changes on IRC.
