kameloso 3.0.0

kameloso

kameloso is an IRC bot.

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, stopwatches
• automatic mode sets (e.g. auto +o on join)
• works on Twitch with some additional 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.

Getting started

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

Prerequisites

kameloso is written in D. It can be built using the reference compiler dmd, which compiles very fast; and the LLVM-based ldc, which is slower at compiling but produces 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. Sadly, the stable release of the GCC-based gdc is currently based on version 2.076 and is thus too old to be used.

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.

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

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

It can also be downloaded as a .zip archive.

Compiling

dub build

This will compile the bot in the default debug mode, which adds some extra code and debugging symbols. You can automatically 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 bot 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 only work with ldc. (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 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. Mind that disabling any of the "service" plugins may/will break the bot in subtle ways.

How to use

Configuration

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 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" \
    --monochrome
    --save

[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 wherever $XDG_DATA_HOME points to; XDG standards remain assumed).

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.

[Core]
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 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 query 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 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 for more information.

Twitch

To connect to Twitch servers you must first build a configuration that includes support for it, which is currently either twitch or dev.

You must also supply an OAuth token pass (not to be confused with password). These authorisation tokens are unique to your user paired with an application. As such, you need a new one for each and every program you want to access Twitch with.

Run the bot with --set twitch.keygen to start the captive process of generating one. 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; generateKey in twitchbot/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 offer to 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 key to disk.

Example configuration

[IRCClient]
nickname            botaccount
user                ignored
realName            likewise

[IRCBot]
#account
#password
pass                personaloauthauthorisationtoken
admins              mainaccount
homeChannels        #mainaccount,#botaccount
#guestChannels

[IRCServer]
address             irc.chat.twitch.tv
port                6697

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

See the wiki page on Twitch for more information.

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
• !timer
• !followage
• !shoutout

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

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

Further help

For more information and help, first see the wiki.

Known issues

Windows

kameloso uses OpenSSL to establish secure connections. It is the de facto standard SSL library 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, supply the --get-openssl flag to download and launch the installer for OpenSSL for Windows, and opt to install to Windows system directories when asked.

Roadmap

• pipedream zero: no compiler segfaults (#18026, #20562)
• please send help: Windows Secure Channel SSL
• split Twitch timers into own plugin
• Twitch ecount, settitle, setgame, vanish/poof, watchtime, roulette, repeat/spam?
• Twitch web server to catch auth key
• help plugin descriptions? multiple syntax entries?
• more pairs of eyes
