About the Bot

Terminus-Bot is an IRC bot written in Ruby under the MIT license.

The authors of the project are long-time IRC bot users and have struggled with most of the other bots that are currently available. We know what sucks, and what we needed, so we created this.

Terminus-Bot is the last bot you'll ever need — the terminus of your search.

It is the first and primary project of the Terminus-Project team.

How to use Terminus-Bot

Installation and Configuration

See doc/GettingStarted.md.

After that, if you are interested in running Terminus-Bot in a Docker container, see doc/Dockerizing.md.

Code Documentation and Guides

Documentation, including most internal and scripting APIs, is hosted at https://terminus-project.org/terminus-bot/doc/index.html. These docs are a work in progress; contributions are welcome!

You may also generate these docs by running yard from the project root (this requires the yard and redcarpet gems).


This is a complete list of all official scripts that are distributed with the bot. Commands provided by each script are listed here. For more complete information on what a command does and how to use it, you should view the on-IRC help for the command by using the help script's HELP command.

In these examples, the command prefix used is @. When using the bot, be sure to use whichever command prefix you set in the core configuration block.


Create and log in to bot accounts. This script is required if you want access to administrative functions.


  • IDENTIFY - Log in to the bot.
  • REGISTER - Register a new account on the bot.
  • PASSWORD - Change your bot account password.
  • FPASSWORD - Change another user's bot account password.
  • LEVEL - Change a user's account level.
  • ACCOUNT - Display information about a user.
  • WHOAMI - Display your current user information if you are logged in.


Manage the bot's core functionality.


  • RELOAD - Reload one or more scripts.
  • UNLOAD - Unload one or more scripts.
  • LOAD - Load the specified script.
  • REHASH - Reload the configuration file.
  • NICK - Change the bot's nick for the current connection.
  • QUIT - Kill the bot.
  • RECONNECT - Reconnect the specified connection.


Announce away status in channel when users are highlighted. This is pretty annoying, but some archaic IRC clients don't know how to mark away users in the nick list, so this can be useful.


  • AWAY - Enable or disable away status announcements for the current channel.


React to ^H, ^W, ^U, and ^Y by displaying the resulting text.

  • ^H - Backspace
  • ^W - Delete last word
  • ^U - Delete line
  • ^Y - Paste buffer (from ^W or ^U)


Convert a number from one numeric base to another.


  • BASE - Convert a number from the specified base to another specified base.
  • HEX - Convert a number between decimal and hexadecimal.


Facilitate PRNG-based role-play battle games. No turn-based enforcement is done, so it is up to the users how to use this. Once a battle is started, interaction is done with IRC actions (/me). For example:

<@Kabaka> @battle start
<Terminus-Bot> Kabaka has started a battle!
<Terminus-Bot> To attack other players, use /me attacks TARGET with ITEM
<Terminus-Bot> You may check the health of active players by using the HEALTH command.
* Kabaka attacks aji with Hammer of Thor
<Terminus-Bot> Kabaka's Hammer of Thor hits aji for 12 damage.
<Terminus-Bot> aji has 88 health remaining.
* aji attacks Kabaka with pointy sticks
<Terminus-Bot> Kabaka absorbs the hit and gains 20 health!
<Terminus-Bot> Kabaka has 120 health remaining.

Starting health, the amount of damage that is possible, and the chance of hits being ineffective is all configurable in terminus-bot.conf. Any players in the channel may join in at any time. In large channels, this can get incredibly hectic, so it is strongly recommended that this script only be used in smaller channels.


  • BATTLE - Start, stop, or reset the battle in the current channel.
  • HEALTH - View the health of all active players in this channel.
  • HEAL - Heal players to maximum health.


Log channel activity to disk. To disable logging for a specific channel, use the bot's script flags to disable the script in those channels. Logs are written to var/terminus-bot/chanlog/ with the file name format server.channel.log.

This script is still experimental and will be subject to extensive changes before beta.


Join and part channels, and maintain the list of channels the bot tries to occupy. Without this script loaded, the bot will not attempt to join any channels and will not rejoin channels the next time it starts.


  • JOIN - Join a channel with optional key.
  • PART - Part a channel
  • CYCLE - Part and then join a channel.
  • JOINCHANS - Force the join channels event.


Lets the bot make decisions for you. There are two types of questions you may ask the bot: Yes/no questions and questions with multiple answers.

To ask a question, begin your message with the bot's commmand prefix followed by a space. For example:

<Kabaka> @ Should I go to bed?
<Terminus-Bot> Kabaka: No

<Kabaka> @ Ruby, Python, or C?
<Terminus-Bot> Kabaka: Ruby

Remember and recall short "factoids." Factoids are short blocks of text. For example:

<Kabaka> @remember Ruby is the best programming language
<Terminus-Bot> I will remember that factoid. To recall it, use FACTOID. To delete, use FORGET.
<Kabaka> @factoid Ruby
<Terminus-Bot> ruby is the best programming language
<Kabaka> @forget ruby
<Terminus-Bot> Factoid forgotten.


  • REMEMBER - Remember the given factoid.
  • FORGET - Forget this factoid.
  • FACTOID - Retrieve a factoid.


Manage the bot's script flags table.

This script is experimental and will be subject to change before beta.

Terminus-Bot allows you to enable or disable scripts per-channel. This is done using script "flags." Flags can be on or off for any script in any channel on any server.

When accessing or modifying the flags table, wildcards are supported.

For example, if we want to disable all scripts on the Freenode network:

<Kabaka> @disable freenode * *

If we want to see what scripts are enabled in the #Terminus-Bot channel on StaticBox:

<Kabaka> @flags freenode #Terminus-Bot *

A short-term, in-memory message history. This is used by the regex script for quick searching of recent messages for subtitution, and can easily be used by other scripts.


Client capability negotiation. With this module loaded, the bot can use modern IRC features such as multi-prefix and SASL to help improve security and reduce bandwidth usage. Loading this module is strongly recommended.


Simplifies HTTP access for scripts. This module handles redirects, timeouts, and headers.


Allows the bot to ignore other users. This is managed by the ignore script.


Provides an easy-to-use way for scripts to act on messages matching regular expressions.

For usage examples, see the Reddit script and others.


Provides an easy-to-use way for scripts to react to URLs the bot sees in chat.

For usage examples, see the title script, Wikipedia script, and others.

First Run

After you've completed configuration of the bot, type ./terminus-bot in the bot's directory. The bot will load all files and then disappear into the background. It should then connect to IRC.

Since it won't join any channels until you tell it to, you'll have to manually open a query with it by typing /query Terminus-Bot (replacing "Terminus-Bot" with whatever nick you gave the bot).

From here, you'll need to register an account with the bot. When writing the configuration file, you should have specified at least one level 10 account in the admins block. Use that account name to register your new account using the register command in the account script.

The bot should inform you that you've been logged in. Go ahead and have it join a channel using the channel script's join command.

Remember, you can use the help script's help command to get a list of commands and help with specific commands.

Reporting Problems

If you get stuck, or if something just isn't working:

  1. Make sure you are running the latest version of Terminus-Bot.
  2. Carefully read the relevant documentation, such as help output, and this README file.
  3. Search all of the issues on the GitGub project.
  4. Either open an issue on GitHub or visit our IRC channel (listed at the top of this README) and ask about the issue there, or do both. Be ready to provide log files. This will probably include chat logs, and will almost definitely include Terminus-Bot logs with DEBUG logging enabled.
