Mediabot - https://teuk.org

Mediabotv3 is a perl Net::Async::IRC bot now tho I started it with Net::IRC which is now deprecated It is still a beta version after all these years but a release is coming up WHAT IS MEDIABOT? Mediabot is a Net::Async::IRC bot tested on Undernet ircu server, Libera and Epiknet (but it may supports other networks) The bot joins a console channel where it will notice its action Go to the Wiki section and read Installation chapter to know how to deploy it. The full documentation is in the Wiki section : https://github.com/teuk/mediabot_v3/wiki

mediabot_v3

I've been coding this bot for a while, and it's time to write documentation (about time) This perl bot is using Net::Async::IRC and a MySQL/MariaDB backend. I tried to make things easier to install by running the configure script but sometimes it needs manual actions. Check the Installation chapter for hints. I hope you'll have fun using mediabot :) TeuK

Installation

Creating a dedicated user

This is an installation example on Debian GNU/Linux 13 (trixie) Add a mediabot user :

sudo useradd -m -s /bin/bash mediabot

Now, give sudo rights to mediabot user and keep in mind that you MUST remove this file after the installation ! If you don't, you let an irc bot running with root privileges (trust me you don't want that).

echo 'mediabot ALL=(ALL) NOPASSWD:ALL' | sudo tee /etc/sudoers.d/mediabot

Required packages installation

Install needed packages :

sudo apt install build-essential mariadb-server mariadb-client libmariadb-dev libmariadb-dev-compat git curl cpanminus chromium yt-dlp

Bot installation

Now get the bot as mediabot user and run configure script :

sudo -iu mediabot
git clone https://github.com/teuk/mediabot_v3
cd mediabot_v3

The following script is supposed to do all the work for DB creation and Perl modules installation (but you may have to do manual actions sometimes) :

./configure

Running the test framework

Before running the bot, you can verify that the core logic is working correctly by running the test suite (no IRC connection required) :

perl t/test_commands.pl

All tests should pass :

[ 01_context.t ]
[ 02_dispatch.t ]
[ 03_auth.t ]
[ 04_mockbot.t ]
============================================================
PASSED : 115/115  (13s)
============================================================

For detailed output of each individual test :

perl t/test_commands.pl --verbose

Available options :

--verbose, -v          Show each test result [OK]/[FAIL]
--filter,  -f <pat>    Run only files matching <pat>  (e.g. --filter 03)
--nick,    -n <nick>   Default nick for test messages  (default: testuser)
--host        <host>   Default hostname                (default: test.host)
--channel, -c <chan>   Default channel                 (default: #test)
--botnick, -b <n>      Bot nick                        (default: mediabot)
--cmdchar     <char>   Command character               (default: !)

Running the live IRC test framework

The live test framework connects a real bot instance and a spy client to an IRC server, creates a dedicated mediabot_test database, runs a series of end-to-end tests, then tears everything down automatically.

Requirements :

• An accessible IRC server (local ircu on localhost:6667 is recommended for speed and reliability)
• sudo mysql access (socket authentication, no password required)
• All Perl dependencies already installed by ./configure

Basic usage against a local ircu server :

perl t/test_live.pl --server localhost --port 6667 --channel '#mbtest'

All tests should pass :

[ 01_connect.t ]
[ 02_commands.t ]
[ 03_auth_live.t ]
============================================================
PASSED : 13/13  (22s)
============================================================

For detailed output of each individual test :

perl t/test_live.pl --verbose --server localhost --port 6667 --channel '#mbtest'

Keep the test database after the run for inspection :

perl t/test_live.pl --keep-db --server localhost --port 6667 --channel '#mbtest'

Available options :

--server, -s  <host>   IRC server              (default: irc.libera.chat)
--port        <port>   IRC port                (default: 6667)
--channel, -c <chan>   Test channel            (default: ##mbtest)
--botnick, -b <nick>   Bot nick                (default: mbtest_XXXX)
--spynick     <nick>   Spy client nick         (default: mbspy_XXXX)
--cmdchar     <char>   Command character       (default: !)
--timeout, -t <sec>    Per-reply timeout       (default: 30)
--keep-db              Keep mediabot_test DB after tests
--verbose, -v          Show each test result [OK]/[FAIL]
--filter, -f  <pat>    Run only files matching <pat>  (e.g. --filter 02)

Running the bot

If everything's ok then test in foreground using your config file e.g :

./mediabot.pl --conf=mediabot.conf

And you should see the bot join on #mediabot console channel :

[06:30:25] * Now talking in #mediabot
[06:31:39] * Joins: mediabot (mediabot@mediabot.mediabot.rules)

To run the bot in daemon mode :

./mediabot.pl --conf=mediabot.conf --daemon

Always have a look at what is going on :

tail -40f mediabot.log

DON'T FORGET TO REMOVE SUDO RIGHTS, THIS IS IMPORTANT ! :

sudo rm -fv /etc/sudoers.d/mediabot

Once you did all that, register your bot and see the commands available in Wiki section : https://github.com/teuk/mediabot_v3/wiki
