kameloso Linux/macOS/Windows Linux Windows Commits since last release

kameloso is an IRC bot. It works as a Twitch bot too, see here.

Current functionality includes:

  • chat monitoring in bedazzling colours or mesmerising monochrome
  • reporting titles of pasted URLs, YouTube video information fetch
  • sed-replacement of messages (s/this/that/ substitution)
  • saving notes to offline users that get played back when they come online
  • logs
  • bugs
  • channel polls, !seen, counters, oneliners, timed announcements, stopwatches, modesets, ...
  • some common Twitch bot features
  • more random stuff and gimmicks

All of the above are plugins and can be disabled at runtime or omitted from compilation entirely. It is modular and easy to extend. A skeletal Hello World plugin is 25 lines of code.

Testing is primarily done on Libera.Chat and on Twitch, so support and coverage is best there.

Please report bugs. Unreported bugs can only be fixed by accident.

To compile it yourself:

$ dub run kameloso -- --server irc.libera.chat --homeChannels "#mychannel" --guestChannels "#d"

## alternatively, guaranteed latest
$ git clone https://github.com/zorael/kameloso.git
$ cd kameloso
$ dub build
$ ./kameloso --server irc.libera.chat --homeChannels "#mychannel" --guestChannels "#d"

If there's anyone talking it should show up on your screen.

Table of contents

Getting started

Grab a pre-compiled binary from under Releases; alternatively, download the source and compile it yourself.


kameloso is written in D. It can be built using the reference compiler dmd, the LLVM-based ldc, and with the latest release of the GCC-based gdc. dmd compiles very fast, while ldc and gdc are slower at compiling but produce faster code. See here for an overview of the available compiler vendors.

You need one based on D version 2.084 or later (January 2019). For ldc this is version 1.14, and for gdc this is release series 12.

If your repositories (or other software sources) don't have compilers new enough, you can use the official install.sh installation script to download current ones, or any version of choice. (gdc is not available via this script.)

The package manager dub is used to facilitate compilation and dependency management. On Windows it comes bundled in the compiler archive, while on Linux it may need to be installed separately. Refer to your repositories.

SSL libraries on Windows

See the known issues section on Windows for information on libraries needed to connect to SSL servers and to allow plugins to access the web via https:// addresses.

Downloading source

$ git clone https://github.com/zorael/kameloso.git

It can also be downloaded as a .zip archive.


$ dub build

This will compile the bot in the default debug mode, which adds some extra code and debugging symbols. You can omit these and perform some optimisations by building it in release mode with dub build -b release. Mind that build times will increase accordingly. Refer to the output of dub build --help for more build types.

Build configurations

There are several configurations in which the bot may be built.

  • application: base configuration
  • twitch: additionally includes Twitch chat support and the Twitch plugin
  • dev: all-inclusive development build equalling everything available, including things like more detailed error messages

All configurations come in -lowmem variants (e.g. application-lowmem, twitch-lowmem, ...) that lower compilation memory required at the cost of increasing compilation time, but so far they do not work with the dmd compiler. (bug #20699)

List configurations with dub build --print-configs. You can specify which to compile with the -c switch. Not supplying one will make it build the default application configuration.

$ dub build -c twitch

If you want to slim down and customise your own build to only compile the plugins you want to use, see the larger versions lists in dub.sdl. Simply add a character to the line corresponding to the plugin(s) you want to omit, thus invalidating the version identifiers and effectively disabling the code it relates to. Mind that disabling any of the "service" plugins may/will break the bot in subtle ways.

How to use


The bot ideally wants the account name of one or more administrators of the bot, and/or one or more home channels to operate in. Without either it's just a read-only log bot, which is also fine. To define these you can either specify them on the command line, with flags listed by calling the program with --help, or generate a configuration file with --save and enter them there.

$ kameloso --save

A new kameloso.conf will be created in a directory dependent on your platform.

Configuration file

  • Linux and other Posix: $HOME/.config/kameloso (alternatively in a kameloso subdirectory of where $XDG_CONFIG_HOME points to; XDG standards are assumed)
  • Windows: %APPDATA%\kameloso
  • macOS: $HOME/Library/Application Support/kameloso

Open the file in a normal text editor.

As a shortcut you can pass --gedit to attempt to open it in a graphical editor, or --edit to open it in your default terminal one, as defined in the $EDITOR environment variable.

Command-line arguments

You can make changes to your configuration file in-place by specyfing some at the command line and adding --save.

$ kameloso \
    --server irc.libera.chat \
    --nickname "kameloso" \
    --admins "you" \
    --homeChannels "#mychannel" \
    --guestChannels "#d,##networking" \

[12:34:56] Configuration written to /home/user/.config/kameloso/kameloso.conf

Settings not touched will keep their values.

Display settings

kameloso's text colours are by default set to go well with dark terminal backgrounds. If you have a bright background, text may be difficult to read (white on white), depending on your terminal emulator. If so, pass the --bright argument, and/or modify the configuration file; brightTerminal under [Core]. The bot uses 7 colours out of 8-colour ANSI, so if one or more colours are too dark or bright even with the right brightTerminal setting, please refer to your terminal appearance settings.

An alternative is to disable colours entirely with --monochrome.

Other files

More server-specific resource files will be created the first time you connect to a server. These include users.json, in which you whitelist which accounts are allowed to access the bot's features on a per-channel basis. Where these are stored also depends on platform; in the case of macOS and Windows they will be put in server-split subdirectories of the same directory as the configuration file, listed above. On Linux and other Posix, under $HOME/.local/share/kameloso (or a kameloso subdirectory of wherever $XDG_DATA_HOME points to; XDG standards remain assumed).

Example use

Online help and commands

Use the !help command for a summary of available bot commands, and !help [plugin] [command] for a brief description of a specific one. The shorthand !help !command also works.

The command prefix (here "!") is configurable; refer to your configuration file. Common alternatives are . (dot), ~ (tilde) and ?, making it .note, ~quote and ?counter respectively.

prefix                      "!"

It can technically be any string and not just one character. It may include spaces if enclosed within quotes, like "please " (making it please note, please quote, ...). Additionally, prefixing commands with the bot's nickname also always works, as in kameloso: seen MrOffline. This is to be able to disambiguate between several bots in the same channel. Moreover, some administrative commands only work when called this way.

Except nothing happens

Before allowing anyone to trigger any restricted functionality, the bot will try to identify that user by querying the server for what services account the accessing user is logged onto, if not already known. For full administrative privileges you will need to be logged in with an account listed in the admins field in the configuration file, while other users may be defined with other permissions in your users.json file. If a user is not logged onto services it is considered as not being uniquely identifiable and cannot be resolved to an account.

In the case of hostmasks mode, the above still applies but "accounts" are derived from hostmasks. See the Admin plugin !hostmask command (and the hostmasks.json file) for how to map hostmasks to would-be accounts. Hostmasks are a weaker solution to user identification but not all servers may offer services. See the wiki entry on hostmasks.


Refer to the wiki page on Twitch for more in-depth information.

Copy paste-friendly concrete setup from scratch

Pre-compiled binaries for Windows and Linux can be found under Releases.

If you're on Windows, you must first install the OpenSSL library. Run this command to download and launch the installer for it, then opt to install to Windows system directories when asked.

kameloso --get-openssl

The rest is common for all platforms.

kameloso --setup-twitch

The --setup-twitch command creates a configuration file with the server address and port already set to connect to Twitch, then opens it up in a text editor.

A line with a leading `#` is disabled, so remove any `#`s from the heads of entries you want to enable.

  • Add your channel to homeChannels. Channel names are account names (which are always lowercase) with a # in front, so the Twitch user Streamer123 would have the channel #streamer123.
  • Optionally add an account name to admins to give them global low-level control of the bot. Owners of channels (broadcasters) automatically have high privileges in the scope of their own channels, so it's not strictly needed.
  • You can ignore nickname, user, realName, account and password, as they're not applicable on Twitch. Do not enter your Twitch password anywhere.
  • Peruse the file for other settings if you want; you can always get back to it by passing --gedit (short for graphical editor).

The program can then be run normally.


It will connect to Twitch, and upon detecting it's missing the authorisation token needed to authenticate with the server it will start the guide to requesting a new one in your terminal. See the "long story" section below for details.

Note that it will request a token for the user you are currently logged in as in your browser. If you want one for a different "bot user" instead, open up a private/incognito window, log in normally to Twitch with the bot account there, and copy/paste this link and follow it in that browser window instead. (Then follow the terminal instructions again.)

After obtaining a token it will save it to your configuration file and reconnect to the server. Provided there were no errors, the bot should now enter your channel. Say something in chat in your browser's chat and it should show in your terminal. If there were errors or snags, please report them.

If you don't like the terminal colouring, --monochrome disables it.

Example configuration

nickname                    doesntmatter
user                        ignored
realName                    likewise

pass                        <twitch.keygen authorisation token for bot account>
admins                      mainaccount
homeChannels                #mainaccount,#botaccount

address                     irc.chat.twitch.tv
port                        6697

enabled                     true
ecount                      true
watchtime                   true
songrequestMode             youtube
songrequestPermsNeeded      whitelist
promoteBroadcasters         true
promoteModerators           true
promoteVIPs                 true

The Twitch SSL port is 6697 (or 443). For non-encrypted traffic, use the default port 6667.

Long story

To connect to Twitch servers you must first build a configuration that includes support for it, which is currently either twitch or dev. All pre-compiled binaries available from under [Releases](https://github.com/zorael/kameloso/releases) already have this built-in.

You will also require an authorisation token. Assuming you have a configuration file set up to connect to Twitch, it will automatically start the guide to requesting one upon connecting, if none is present. Run the bot with --set twitch.keygen to force it if it doesn't, or if your token expired. (They last for about 60 days.)

It will open a browser window, in which you are asked to log onto Twitch on Twitch's own servers. Verify this by checking the page address; it should end with .twitch.tv, with the little lock symbol showing the connection is secure.

Note: At no point is the bot privy to your Twitch login credentials! The logging-in is wholly done on Twitch's own servers, and no information is sent to any third parties. The code that deals with this is open for audit; requestTwitchKey in plugins/twitch/keygen.d.

After entering your login and password and clicking Authorize, you will be redirected to an empty "this site can't be reached" or "unable to connect" page. Copy the URL address of it and paste it into the terminal, when asked. It will parse the address, extract your authorisation token, and save it to your configuration file.

If you prefer to generate the token manually, here is the URL you need to follow. The only thing the generation process does is open it for you, and automate saving the end token to your configuration file (as pass under [IRCBot]).

Twitch bot

Please make the bot a moderator to prevent its messages from being as aggressively rate-limited.

Assuming a prefix of !, commands to test are:

  • !start, !uptime, !stop
  • !followage
  • !vanish
  • !repeat
  • !ecount
  • !watchtime
  • !nuke
  • !songrequest
  • !settitle
  • !setgame
  • !commercial
  • !startpoll/!endpoll (highly experimental, need help from affiliate)

...alongside !oneliner, !counter, !timer, !poll (chat poll), !stopwatch, and other non-Twitch-specific commands. Try !help or the wiki.

Note: . (dot) and / (slash) prefixes will not work on Twitch.

Song requests

To get song requests to work, you need to register an application to interface with Google (YouTube) and/or Spotify servers individually. To initiate the guides for this, pass --set twitch.googleKeygen for YouTube and --set twitch.spotifyKeygen for Spotify, then simply follow the on-screen instructions. (They behave much like --set twitch.keygen.)

Certain commands require higher permissions

Some functionality, such as setting the channel title or currently played game, require elevated credentials with the permissions of the channel owner (broadcaster). As such, if you want to use such commands, you will need to generate an OAuth authorisation token for your main account separately, much as you generated one for the bot account. This will request a token from Twitch with more permissions, and the authorisation browser page should reflect this.

$ kameloso --set twitch.superKeygen

Mind that you need to be logged into Twitch (in your browser) with your main account while doing this, or the token obtained will be with permissions for the wrong channel.

Known issues


kameloso uses OpenSSL to establish secure connections. It is the de facto standard library for making secure connections in the Posix sphere (Linux, macOS, ...), but not so on Windows. If you run into errors about missing SSL libraries when attempting to connect on Windows, pass the --get-openssl flag to download and launch the installer for OpenSSL for Windows v1.1.\*. Make sure to opt to install to Windows system directories when asked.
