README

        
============================

ivar2 - DO-OH!

============================

Introduction

------------

ivar2 is an IRC/Matrix bot on speed, with a mentally unstable mind.

Partially because its written in Lua, which could make the most sane mind go unstable.

If that's not obscure enough for you, ivar2 also supports running `MoonScript `_ modules.

Installation

------------------

The installation instructions are made for Debian Jessie, you might have to adapt yourself for other distributions. Some additional dependencies are required for some of the modules, like PostgreSQL for pgolds.lua. Persisting data can be done using either sqlite og Redis, naturally lua-redis and redis-server is required as a dependency if you want to use redis.

Instructions for containing Lua and all deps inside a single directory, almost like python virtualenv or npm.:

::

    # Install ``hererocks`` , using pip or wget https://raw.githubusercontent.com/mpeterv/hererocks/latest/hererocks.py

    pip install hererocks

    # Install lua + deps in a directory called ivarenv

    hererocks -j 2.1 -r\^ ivarenv

    # Change dir to ivarenv

    cd ivarenv

    # Run Luarocks from ivarenv

    bin/luarocks install http

    bin/luarocks install lua-cjson

    bin/luarocks install lua-zlib

    bin/luarocks install lua-iconv

    bin/luarocks install luafilesystem

    bin/luarocks install lsqlite3

    # Optional

    bin/luarocks install --server=http://luarocks.org/dev cqueues-pgsql  PQ_INCDIR=/usr/include/postgresql # requires libpq-dev system package

    # Optional

    bin/luarocks install --server=http://luarocks.org/dev lredis

    # Now you have a self contained Lua environment with deps that you can run the bot.

    cd ivar2

    ivarenv/bin/lua ivar2.lua myconfig.lua

Alternate instructions for install Lua(JIT) + deps, trying to use some system packages:

::

    sudo apt-get install luarocks liblua5.1-iconv0 lua-zlib lua-cjson cmake libsqlite3-dev git libssl-dev m4

    sudo luarocks install lsqlite3

    sudo luarocks install luabitop

    sudo luarocks install luarocks #newer version of luarocks to support git+https

    sudo luarocks install http

    sudo luarocks install luafilesystem

    # if you want to use LuaJIT instead of Lua

    sudo apt-get install luajit

    # if you want postgresql support

    sudo luarocks install --server=http://luarocks.org/dev cqueues-pgsql  PQ_INCDIR=/usr/include/postgresql # requires libpq-dev system package

    # if you want redis persist

    sudo luarocks install --server=http://luarocks.org/dev lredis

    sudo apt-get install redis-server

Decompress the required data files in cache directory.

Configuration File

------------------

Create a bot config sort of like this

**myconfig.lua**

.. code:: lua

    return {

        nick = 'ivar2',

        autoReconnect = true,

        ident = 'ivar2',

        uri = 'tcp://irc.efnet.no:6667/',

        password = false,

        realname = 'ivar',

        owners = {

            '[email protected]'

        },

        webserverhost = '::',

        webserverport = 9000,

        webserverprefix = 'https://my.web.proxy/', -- optional URL if bot is behind proxy

        commandPattern = "!",

        notice = false, -- Reply with PRIVMSG instead of NOTICE

        modules = {

            'admin',

            'autojoin',

            'lastfm',

            'spotify',

            'karma',

            'roll',

            'title',

            'tvrage',

            'urbandict',

            'substitute',

            'lua',

        },

        channels = {

            ['#ivar'] = {

                disabledModules = {

                    'olds'

               },

               commandPattern = '>',

               ignoredNicks = {'otherbot'},

               modulePatterns = {

                    lastfm = '#',

               },

            },

        }

    }

Launch bot

----------

::

    # Using Lua

    lua ivar2.lua myconfig.lua

    # Using LuaJIT (apt-get install luajit)

    luajit ivar2.lua myconfig.lua

    # If you want to try the Matrix adapter

    lua(jit) matrix.lua yourmatrixconfigfile.lua

    # Or install the provided systemd service

    sudo cp scripts/ivar2.service /etc/systemd/system/ivar2.service

    sudo systemctl daemon-reload

    sudo systemctl start ivar2

Modules

-------

So. Many. Useless. Modules!

And they are written in either Lua or MoonScript.

Writing modules

---------------

Example module that fetches some content over HTTP, parses JSON and returns some text when triggered:

.. code:: lua

    -- Util lib contains lots of helpful stuff for modules, like HTTP, JSON,

    -- IRC formatting, some utf8-helpers, etc.

    local util = require'util'

    local http = util.simplehttp

    local json = util.json

    -- Define function that will be ran when triggered by user input

    local handler = function(self, source, destination, input)

      -- self is ivar2 object, with all its methods

      -- source is table, containing sender info, like source.nick

      -- destination is string with target of the message, i.e. the channel the message was sent to

      -- input is optional Lua pattern capture match

      -- Fetch HTTP content and JSON decode it. No error handling needed here

      -- unless you want to inform the user of errors with HTTP or JSON etc.

      -- All module functions are called with pcall (protected call) to prevent

      -- crashes. Errors will result in error lines in the log.

      local result = json.decode((http'http://api.icndb.com/jokes/random'))

      -- Send the reply back to the destination where it came from using ivar2

      -- Privmsg function. You could also use say() or reply() available in this

      -- function environment as helpers

      self:Privmsg(destination, result.value.joke)

    end

    -- Modules returns a table with events, and Lua pattern with a corresponding

    -- function that will be called when the event text matches the pattern.

    return {

      -- PRIVMSG means incoming IRC message, from channel or query

      PRIVMSG = {

        ['!chuck'] = handler,

      },

    }

Example of module that is responding to HTTP:

.. code:: lua

    ivar2.webserver.regUrl('/test/html/(.*)', function(self, req, res)

       self:Log('error', 'testtestest')

       local channel = req.url:match('channel=(.+)%s*')

       local unescaped_channel = channel:gsub('%%23', '#')

       self:Privmsg(unescaped_channel, 'test')

       return [[

       

           

                ivartest 

           

           

               


                   Test

               

           

       

       ]]

     end)


     ivar2.webserver.regUrl('/test/plain/(.*)', function(self, req, res)

       self:Log('error', 'testtestest')

       return 'ok', 200, {

         ['Content-Type'] = 'text/plain'

       }

     end)
