kameloso ~bash2

kameloso is an IRC bot. It is text-based and runs in your terminal or console.

So what does it do

• real-time chat monitoring
• channel polls, user quotes, !seen, counters, oneliner commands, recurring timed announcements, ...
• saving notes to offline users that get played back when they come online
• reporting titles of pasted URLs, YouTube video information
• sed-like replacement of messages (s/this/that/ substitution)
• Twitch support with some common bot features
• logs
• bugs

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 less than 30 lines of code.

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

tl;dr

-n       --nickname Nickname
-s         --server Server address [irc.libera.chat]
-P           --port Server port [6667]
-A        --account Services account name
-p       --password Services account password
           --admins Administrators' services accounts, comma-separated
-H   --homeChannels Home channels to operate in, comma-separated
-C  --guestChannels Non-home channels to idle in, comma-separated
           --bright Adjust colours for bright terminal backgrounds
            --color Use colours in terminal output (auto|always|never)
             --save Write configuration to file

Prebuilt binaries for Windows and Linux can be found under Releases.

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 on your screen.

Getting started

Grab a prebuilt Windows or Linux binary from under Releases (64-bit only); alternatively, download the source and compile it yourself.

Prerequisites

The program can be built using the D reference compiler dmd, with the LLVM-based ldc and with the GCC-based gdc. dmd compiles very fast, while ldc and gdc are slower at compiling but produce faster code. Additionally, the latter two support more target architectures than dmd does (e.g. ARM). See here for an overview of the available compiler vendors.

You will need a compiler based on D version 2.086 or later (May 2019). For ldc you require a minimum of version 1.18, while for gdc you broadly need release series 12.

Some compiler versions exhibit bugs that may cause building to fail. If you run into errors when building, try updating to a newer compiler version.

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

The package manager dub is used to facilitate compilation and dependency management. On Windows it is included 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 make encrypted connections to IRC servers, and to allow plugins secure access to the Internet.

Downloading source

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 build type, which adds some extra code and debugging symbols. You can omit these and have the compiler perform some optimisations by building it in release mode, by calling dub build -b release. Mind that build times will increase accordingly.

It is recommended that you use ldc for release builds.

• gdc is very slow to compile.
• ldc optimisations are objectively better than those of dmd.
• You may experience memory corruption and/or crashes with dmd in release mode. (File an issue if you do!)

Refer to the output of dub --annotate --print-builds for more build types.

Build configurations

There are two major configurations in which the bot may be built.

• application: base configuration; everything needed for an IRC bot
• twitch: additionally includes Twitch chat support and the Twitch bot plugin

Both configurations come in -lowmem variants; application-lowmem and twitch-lowmem; that lower compilation memory required at the cost of increased compilation time. This may help on memory-constrained systems, such as the Raspberry Pi.

List configurations with dub --annotate --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 thin down the program 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 lines corresponding to the plugins you want to omit, thus invalidating the version identifiers and effectively disabling the code they relate to. 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 services 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 admittedly also a completely valid use-case. To define these you can either supply them on the command line, by use of flags listed by calling the program with --help, or by generating a configuration file with --save and entering them in 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/ (overridden by $XDG_CONFIG_HOME)
• Windows: %APPDATA%\kameloso\
• macOS: $HOME/Library/Preferences/kameloso/

Open the file in a normal text editor.

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

Command-line arguments

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

$ ./kameloso \
    --server irc.libera.chat \
    --nickname "mybot" \
    --admins "me" \
    --homeChannels "#mychannel" \
    --guestChannels "#d,##networking" \
    --color=never \
    --save

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

Settings not touched will keep their values.

Display settings

The bot uses terminal ANSI colouring and text colours are by default set to go well with dark terminal backgrounds. If you instead have a bright background, text may be difficult to read (e.g. white on white), depending on your terminal emulator. If so, try passing the --bright argument, or modify the configuration file to enable brightTerminal under [Core] to make the setting persistent. If only some colours work, try limiting colouring to only those by disabling extendedColours, also under [Core]. If one or more colours are still too dark or too bright even with the right brightTerminal setting, please refer to your terminal appearance settings.

An alternative is to disable colours entirely with --color=never.

Other files

More server-specific resource files will be created the first time you connect to a server. Where these are placed is platform-dependent.

• Linux and other Posix: $HOME/.local/share/kameloso/ (overridden by $XDG_DATA_HOME)
• Windows: %LOCALAPPDATA%\kameloso\
• macOS: $HOME/Library/Application Support/kameloso/

Example use

Refer to the wiki for more information on available plugins and their commands. Additionally, see this section about permissions if nothing happens when you try to invoke commands.

Online help and commands

Use the !help command of the Help plugin 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 always works, as in kameloso: seen MrOffline. Many administrative commands only work when called this way; notably everything that only outputs information to the local terminal.

If an empty prefix is set, commands may only be called by prefixing them with the bot's nickname.

Except nothing happens

Before allowing anyone to trigger any restricted functionality, the bot will try to identify the accessing user by querying the server for what services account that user is logged onto, if not already known. For full and global administrative privileges you will need to be logged into services with an account listed in the admins field in the configuration file. Other users may be defined with other per-channel permissions in your users.json file placed in your resource directory, which can be managed online by commands provided by the Admin plugin.

If a user is not logged onto services, it is considered as not being uniquely identifiable, and thus cannot be resolved to an account.

Not all servers offer services, and in those cases you can enable hostmasks mode. With it enabled, the above still applies but "accounts" are derived from user hostmasks. See the !hostmask command of the same Admin plugin (and the hostmasks.json resource file) for how to map hostmasks to would-be accounts. Hostmasks are a weaker solution to user identification, but it's better than nothing if services aren't available.

Twitch

If you're interested in trying the bot but don't want to run it yourself, [contact me](mailto:[email protected]?subject=Hosting+a+kameloso+instance) and I will host an instance for you on a headless server.

Copy paste-friendly concrete setup from scratch

Prebuilt binaries for Windows and Linux can be found under Releases (64-bit only).

If you're on Windows, you must first install the OpenSSL library. Navigate to where you downloaded the kameloso.exe executable, then run the following command to download and launch the OpenSSL installer. When asked, make sure to opt to install to Windows system directories.

Here in Powershell syntax:

./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 for general use, but may be a good idea to have while you're setting things up.
• You can ignore nickname, user, realName, account and password, as they're not applicable on Twitch. Do not enter your Twitch password anywhere in this file.
• 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.

./kameloso

It should now start a terminal wizard requesting a new authorisation token, upon detecting it's missing one. 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 into Twitch normally with the bot account there, copy this link, then follow it in that browser window instead. After that, refer to 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 your chat in your browser and it should show in your terminal. If there were errors or snags, or if something was simply unintuitive, please file an issue so the process can be improved upon.

If you don't like the terminal colours, --color=never disables them.

Example configuration

[IRCClient]
nickname                    doesntmatter
user                        ignored
realName                    likewise

[IRCBot]
#account
#password                   (ignore; do NOT enter your Twitch account password!)
pass                        (twitch.keygen authorisation token for bot account)
admins                      mainaccount
homeChannels                #mainaccount,#botaccount
#guestChannels

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

[Twitch]
enabled                     true
ecount                      true
watchtime                   true
watchtimeExcludesLurkers    true
songrequestMode             youtube
songrequestPermsNeeded      whitelist
mapWhispersToChannel        false
promoteBroadcasters         true
promoteModerators           true
promoteVIPs                 true
workerThreads               3

The port to use for secure traffic is 6697 (alternatively 443). For a non-encrypted connection, while heavily discouraged, use the default port 6667.

Long story

To connect to Twitch servers, you must first compile the twitch build configuration to include Twitch support. All pre-compiled binaries available from under [Releases](https://github.com/zorael/kameloso/releases) are already built this way.

You will also require an authorisation token. Assuming you have a configuration file set up to connect to Twitch, it will automatically start a terminal wizard requesting one on program startup, 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 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.

Do note that 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 all this is open for audit; requestTwitchKey in plugins/twitch/providers/twitch.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 prompted to. It will parse the address, extract your authorisation token, save it to your configuration file, and then finally connect to the server.

If you prefer to generate the token manually, here is the URL you need to follow. The key generation wizard only opens it for you, as well as automates saving the resulting token to your configuration file (as pass under [IRCBot]).

Mind that the authorisation token should be kept secret. It's not possible to derive your Twitch account password from it, but anyone with access to it can chat as if they were you.

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:

• !uptime
• !followage
• !vanish
• !repeat
• !ecount
• !watchtime
• !nuke
• !songrequest
• !settitle
• !setgame
• !commercial
• !shoutout
• !startpoll/!endpoll (highly experimental and unlikely to work unwil we can perform some live testing, which requires the help of a Twitch affiliate)
• !subs

...alongside !oneliner, !counter, !timer, !poll (chat variant), !time, !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 be able to serve song requests, you need to register an application to interface with Google (YouTube) and/or Spotify servers individually. To initiate the wizards for this, pass --set twitch.googleKeygen for YouTube and --set twitch.spotifyKeygen for Spotify, and follow the on-screen instructions. (They behave much like --set twitch.keygen.)

You may set up access tokens for both song request providers, but only one may be enabled at any one time. To control which, set songrequestMode to either youtube or spotify in your configuration file. A value of disabled disables the feature entirely.

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 opposed to those of any moderator. 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 to be able to connect with the bot account. This will request a token from Twitch with different 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 (broadcaster) account while doing this, or the token obtained will be with permissions for the wrong channel. This is in contrast to --set twitch.keygen, with which it is recommended you use a separate bot account.

All keygens can be triggered at the same time.

./kameloso \
    --set twitch.keygen \
    --set twitch.superKeygen \
    --set twitch.googleKeygen \
    --set twitch.spotifyKeygen

Known issues

Windows

The bot uses OpenSSL to establish secure connections. It is the de facto standard library for such 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 v3.2.\* _Light_. When asked, make sure to opt to install to Windows system directories.

YouTube song request playlist integration errors

If you're seemingly doing everything right and you still get permissions errors when attempting to add a YouTube video clip to a playlist, redo the Google keygen. When you're asked to pick one of your accounts late in the process, make sure that you select a YouTube account , as opposed to an overarching Google account. It should say YouTube underneath the option.
