Sircbot is a simple irc bot based in lua script.

Install sircbot

apk add sircbot lua-sircbot

Configue sircbot

vi /etc/conf.d/sircbot

Change name, server and channel

sircbot_opts="-n name -s server"
sircbot_channels="#channel"

Create sircbot scripts folders and files

Sircbot will use an folder for the channel where is logged in. Lets say we will use it at the "test" channel. The folder path is: /etc/sircbot.d/#channel

Example

Lets see an example:

Our bot will be named kumquat and we will join at the #test channel in the irc.ddd.ddd server.

vi /etc/conf.d/sircbot

Change name, server and channel

sircbot_opts="-n kumquat -s irc.ddd.ddd"
sircbot_channels="#test"

Create folder bot.

mkdir /etc/sircbot.d/#test -p

Create the lua scrip file for our bot.

vi /etc/sircbot.d/#test/commands

#!/usr/bin/lua

-- Scripts for kumquat in Lua

args={...}

sender=args[1]   	-- is the nickname of running the command on IRC
message=args[2] 	-- is the message or command typed
channel=args[3] 	-- is the channel name

os.execute("sleep " .. tonumber(1))

-- This command will show: What can i do for you "nickname"?
local kumquatresult = string.find(message, "kumquat") 
  if kumquatresult ~= nil then
  command="echo 'What can i do for you '"..sender.."'?' | sircbot-send '"..channel.."'"
  io.popen(command)
end

-- This command will show: Hello there, amigo "nickname"
local kumquatresult = string.find(message, "hi")
  if kumquatresult ~= nil then
  command="echo 'Hello there, amigo '"..sender.." | sircbot-send '"..channel.."'"
  io.popen(command)
end

-- This command will show the current UTC date and time
local kumquatresult = string.find(message, "date")
  if kumquatresult ~= nil then
  command="date -u | sircbot-send '"..channel.."'"
  io.popen(command)
end

-- This command will do a search for a alpine linux package
local kumquatresult = string.find(message, "apk search:[^%d]")
if kumquatresult ~= nil then
  local strng = (string.sub(message, 12))
  command="apk search"..strng.." | sircbot-send '"..channel.."'"    
  io.popen(command)
end
 
-- This command will resolve a host name and ip
local kumquatresult = string.find(message, "host:[^%d]")
if kumquatresult ~= nil then
  local strng = (string.sub(message, 6))
  command="host "..strng.." | sircbot-send '"..channel.."'"    
  io.popen(command)
end

-- This command will do a 3 times ping to a server or ip address
local kumquatresult = string.find(message, "ping:[^%d]")
if kumquatresult ~= nil then
  local strng = (string.sub(message, 6))
  command="ping -c 3 "..strng.." | sircbot-send '"..channel.."'"    
  io.popen(command)
end

Make the script to be executable

chmod +x /etc/sircbot.d/#test/commands
