HyperNerd

Second iteration of Tsoder. Chat bot for Tsoding streams.

Quick Start

NixOS

$ nix-shell
$ cabal configure
$ cabal build
$ cabal test
$ cabal exec hlint .
$ cabal run secret.ini database.db

Stack

Native dependencies:

OpenSSL
zlib

$ stack build
$ stack exec hlint .
$ stack exec HyperNerd secret.ini database.db

Example of a secret.ini file

The secret.ini file consist of a single section Bot the format of which depends on its type.

[Bot]
type = twitch|discord
...
... the rest of the parameters ...
...

Twitch Bot

[Bot]
type = twitch
nick = HyperNerd
owner = <your-name>
password = 12345
channel = Tsoding
clientId = <client-id-token>

name	description
`nick`	Nickname of the bot.
`owner`	Owner of the bot. The bot will recognize this name as an authority regardless of being a mod or broadcaster.
`password`	Password generated by https://twitchapps.com/tmi/.
`channel`	Channel that the bot will join on start up.
`clientId`	Client ID for Twitch API calls.

Discord Bot

type = discord
authToken = <auth-token>
guild = <guild-id>
channel = <channel-id>
clientId = <client-id-token>

name	description
`authToken`	Authentication Token for the bot: https://github.com/reactiflux/discord-irc/wiki/Creating-a-discord-bot-&-getting-a-token
`guild`	The id of the guild the bot listens to
`channel`	The id of the channel the bot listens to
`clientId`	Client ID for Twitch API calls.

Debug Bot

TBD

Docker

$ docker build -t hypernerd .
$ mkdir hypernerd-state
$ cp secret.ini hypernerd-state
$ docker create -v /absolute/path/to/hypernerd-state/:/tmp/hypernerd/ \
                --name hypernerd-bot hypernerd
$ docker start -a hypernerd-bot
$ docker stop hypernerd-bot

Markov Chain Responses

To trigger a Markov chain response, just mention the bot in the chat.

Training the Markov Model

The Markov model is a csv file that is generated from the logs in the bot's database file using the Markov CLI utility:

$ cabal exec Markov database.db markov.csv

This command will produce the markov.csv file.

Using the Trained Markov Model with the Bot

$ cabal exec HyperNerd secret.ini database.db markov.csv

The markov.csv file is not automatically updated. To update the file with the new logs you have to run the Markov CLI utility again.

Command Aliases

You can assign a command alias to any command:

<user> !test
<bot> test
<user> !addalias foo test
<user> !foo
<bot> test

The aliases are "redirected" only one level deep meaning that transitive aliases are not supported:

<user> !addalias bar foo
<user> !bar
*nothing, because !bar is redirected to !foo, but further redirect from !foo to !test does not happen*

Motivation to not support transitive aliases is the following:

They are not needed in most of the cases. Generally you just have a main command and a bunch of aliases to it.
Support for transitive aliases requires to traverse and maintain a "tree" of aliases, which complicates the logic and degrades the performance.

!addquote <quote-text> -- Add a quote to the quote database. Available only to subs and mods.
