Tenyks is a computer program designed to relay messages between connections to

IRC networks and custom built services written in any number of languages.

More detailed, Tenyks is a service oriented IRC bot rewritten in Go.

Service/core communication is handled by ZeroMQ 4 PubSub via json payloads.



The core acts like a relay between IRC channels and remote services. When a

message comes in from IRC, that message is turned into a json data structure,

then sent over the pipe on a Pub/Sub channel that services can subscribe to.

Services then parse or pattern match the message, and possibly respond back via

the same method.



This design, while not anything new, is very flexible because one can write

their service in any number of languages. The current service implementation

used for proof of concept is written in Python. You can find that

[here](https://github.com/kyleterry/tenyks-service). It's also beneficial because you can take down

or bring up services without the need to restart the bot or implement a

complicated hot pluggable core. Services that crash also don't run the risk of

taking everything else down with it.



## Installation and whatnot



### Building



Current supported Go version is 1.7. All packages are vendored with Godep and

stored in the repository. I update these occasionally. Make sure you have a

functioning Go 1.7 environment.



1. Install ZeroMQ4 (reference your OSs package install documentation) and make

   sure libzmq exists on the system.

1. `go get github.com/kyleterry/tenyks`

1. `cd ${GOPATH}/src/github.com/kyleterry/tenyks`

1. `make` - this will run tests and build

1. `sudo make install` - otherwise you can find it in `./bin/tenyks`

1. `cp config.json.example config.json`

1. Edit `config.json` to your liking.



### Uninstall



Why would you ever want to do that?



```bash

cd ${GOPATH}/src/github.com/kyleterry/tenyks

sudo make uninstall

```



### Docker



There is a Docker image on Docker hub called `kyleterry/tenyks`. No

configuration is available in the image so you need to use it as a base image.

You can pass your own configuration in like so:



```docker

FROM kyleterry/tenyks:latest

COPY my-config.json /etc/tenyks/config.json

```



Then you can build your image: `docker build -t myuser/tenyks .` and run it

with: `docker run -d -P --name tenyks myuser/tenyks`.



### Binary Release



You can find binary builds on [bintray](https://dl.bintray.com/kyleterry/tenyks/).



I cross compile for Linux {arm,386,amd64} and Darwin {386,amd64}.



### Configuration



Configuration is just json. The included example contains everything you need to

get started. You just need to swap out the server information.



```bash

cp config.json.example ${HOME}/tenyks-config.json

```



### Running



`tenyks ${HOME}/tenyks-config.json`



If a config file is excluded when running, Tenyks will look for configuration

in `/etc/tenyks/config.json` first, then

`${HOME}/.config/tenyks/config.json` then it will give up. These are defined

in tenyks/tenyks.go and added with ConfigSearch.AddPath(). If you feel more

paths should be searched, please feel free to add it and submit a pull request.



### Vagrant



If you want to play _right fucking now_, you can just use vagrant: `vagrant up`

and then `vagrant ssh`. Tenyks should be built and available in your `$PATH`.

There is also an IRC server running you can connect to server on `192.168.33.66` with your IRC client.



Just run `tenyks & && disown` from the vagrant box and start playing.



## Testing



I'm a horrible person. ~~There aren't tests yet. I'll get right on this...~~.

There are only a few tests.



## Builtins



Tenyks comes with very few commands that the core responds to directly. You can

get a list of services and get help for those services.



`tenyks: !services` will list services that have registered with the bot

through the service [registration API.](#service-registration).  

`tenyks: !help` will show a quick help menu of all the commands available to

tenyks.  

`tenyks: !help servicename` will ask the service to sent their help message to

the user.



## Services



### Libraries

* [tenyksservice](https://github.com/kyleterry/tenyks-service) (Python)

* [quasar](https://github.com/kyleterry/quasar) (Go)



### To Services



Example JSON payload sent to services:



```json

{

    "target":"#tenyks",

    "command":"PRIVMSG",

    "mask":"unaffiliated/vhost-",

    "direct":true,

    "nick":"vhost-",

    "host":"unaffiliated/vhost-",

    "full_message":":vhost-!~vhost@unaffiliated/vhost- PRIVMSG #tenyks :tenyks-demo: weather 97217",

    "user":"~vhost",

    "from_channel":true,

    "connection":"freenode",

    "payload":"weather 97217",

    "meta":{

        "name":"Tenyks",

        "version":"1.0"

    }

}

```



### To Tenyks for IRC



Example JSON response from a service to Tenyks destined for IRC



```json

{

    "target":"#tenyks",

    "command":"PRIVMSG",

    "from_channel":true,

    "connection":"freenode",

    "payload":"Portland, OR is 63.4 F (17.4 C) and Overcast; windchill is NA; winds are Calm",

    "meta":{

        "name":"TenyksWunderground",

        "version":"1.1"

    }

}

```



### Service Registration



Registering your service with the bot will let people ask Tenyks which services

are online and available for use. Registering is not requires; anything

listening on the pubsub channel can respond without registration.



Each service should have a unique UUID set in it's REGISTER message. An example

of a valid register message is below:



```json

{

    "command":"REGISTER",

    "meta":{

        "name":"TenyksWunderground",

        "version":"1.1",

        "UUID": "uuid4 here",

        "description": "Fetched weather for someone who asks"

    }

}

```



### Service going offline



If the service is shutting down, you should send a BYE message so Tenyks doesn't

have to timeout the service after PINGs go unresponsive:



```json

{

    "command":"BYE",

    "meta":{

        "name":"TenyksWunderground",

        "version":"1.1",

        "UUID": "uuid4 here",

        "description": "Fetched weather for someone who asks"

    }

}

```



### Commands for registration that go to services



Services can register with Tenyks. This will allow you to list the services

currently online from the bot. This is not persistent. If you shut down the bot,

then all the service UUIDs that were registered go away.



The commands sent to services are:



```json

{

  "command": "HELLO",

  "payload": "!tenyks"

}

```  

`HELLO` will tell services that Tenyks has come online and they can register if

they want to.



```json

{

  "command": "PING",

  "payload": "!tenyks"

}

```  

`PING` will expect services to respond with `PONG`.



List and Help commands are coming soon.



### Lets make a service!



This service is in python and uses the

[tenyks-service](https://github.com/kyleterry/tenyks-service) package. You can

install that with pip: `pip install tenyksservice`.



```python

from tenyksservice import TenyksService, run_service, FilterChain



class Hello(TenyksService):

    irc_message_filters = {

        'hello': FilterChain([r"^(?i)(hi|hello|sup|hey), I'm (?P(.*))$"],

                             direct_only=False),

        # This is will respond to /msg tenyks this is private

        'private': FilterChain([r"^this is private$"],

                             private_only=True)

    }



    def handle_hello(self, data, match):

        name = match.groupdict()['name']

        self.logger.debug('Saying hello to {name}'.format(name=name))

        self.send('How are you {name}?!'.format(name=name), data)



    def handle_private(self, data, match):

        self.send('Hello, private message sender', data)



def main():

    run_service(Hello)



if __name__ == '__main__':

    main()

```



Okay, we need to generate some settings for our new service.



```bash

tenyks-service-mkconfig hello >> hello_settings.py

```



Now lets run it: `python main.py hello_settings.py`



If you now join the channel that tenyks is in and say "tenyks: hello, I'm Alice"

then tenyks should respond with "How are you Alice?!".



### More Examples



There is a repository with some services on my Github called

[tenyks-contrib](https://github.com/kyleterry/tenyks-contrib). These are all

using the older tenyksclient class and will probably work out of the box with

Tenyks. I'm going to work on moving them to the newer

[tenyks-service](https://github.com/kyleterry/tenyks-service) class.



A good example of something more dynamic is the [Weather

service](https://github.com/kyleterry/tenyks-contrib/blob/master/src/tenykswunderground/main.py).



## Credit where credit is due



Service oriented anything isn't new. This idea came from an old

[coworker](https://github.com/wraithan) of mine. I just wanted to do something

slightly different. There are also plenty of other plugin style bots (such as

hubot and eggdrop). Every open source project needs love, so check those out as

well.
