IRC Mod API
===========
This file documents the Minetest IRC mod API.
Basics
------
In order to allow your mod to interface with this mod, you must add `irc`
to your mod's `depends.txt` file.
Reference
---------
irc:say([name,] message)
Sends <message> to either the channel (if <name> is nil or not specified),
or to the given user (if <name> is specified).
Example:
irc:say("Hello, Channel!")
irc:say("john1234", "How are you?")
irc:register_bot_command(name, cmdDef)
Registers a new bot command named <name>.
When an user sends a private message to the bot with the command name, the
command's function is called.
Here's the format of a command definition (<cmdDef>):
cmdDef = {
params = "<param1> ...", -- A description of the command's parameters
description = "My command", -- A description of what the command does. (one-liner)
func = function(user, args)
-- This function gets called when the command is invoked.
-- <user> is a user table for the user that ran the command.
-- (See the LuaIRC documentation for details.)
-- It contains fields such as 'nick' and 'ident'
-- <args> is a string of arguments to the command (may be "")
-- This function should return boolean success and a message.
end,
};
Example:
irc:register_bot_command("hello", {
params = "",
description = "Greet user",
func = function(user, param)
return true, "Hello!"
end,
});
irc.joined_players[name]
This table holds the players who are currently on the channel (may be less
than the players in the game). It is modified by the /part and /join chat
commands.
Example:
if irc.joined_players["joe"] then
-- Joe is talking on IRC
end
irc:register_hook(name, func)
Registers a function to be called when an event happens. <name> is the name
of the event, and <func> is the function to be called. See HOOKS below
for more information
Example:
irc:register_hook("OnSend", function(line)
print("SEND: "..line)
end)
This mod also supplies some utility functions:
string.expandvars(string, vars)
Expands all occurrences of the pattern "$(varname)" with the value of
'varname' in the <vars> table. Variable names not found on the table
are left verbatim in the string.
Example:
local tpl = "$(foo) $(bar) $(baz)"
local s = tpl:expandvars({foo=1, bar="Hello"})
assert(s == "1 Hello $(baz)")
In addition, all the configuration options decribed in `README.txt` are
available to other mods, though they should be considered read-only. Do
not modify these settings at runtime or you might crash the server!
Hooks
-----
The `irc:register_hook` function can register functions to be called
when some events happen. The events supported are the same as the LuaIRC
ones with a few added (mostly for internal use).
See src/LuaIRC/doc/irc.luadoc for more information.

IRC Mod for Minetest
====================
Introduction
------------
This mod is just a glue between IRC and Minetest. It provides two-way
communication between the in-game chat, and an arbitrary IRC channel.
The forum topic is at http://minetest.net/forum/viewtopic.php?id=3905
Installing
----------
Quick one line install for linux:
cd <Mod directory> && git clone https://github.com/kaeza/minetest-irc.git irc && cd irc && git submodule update --init
Please change `<Mod directory>` to fit your installation of minetest.
For more information, see [the wiki](http://wiki.minetest.net/Installing_mods).
The Minetest IRC mod uses submodules, therefore you will have to run
`git submodule init` when first installing the mod, and `git submodule update`
every time that a submodule is updated. These steps can be combined as
`git submodule update --init`.
The Minetest IRC mod also requires LuaSocket. This can be installed using your
package manager on many distributions, for example on Arch Linux:
# pacman -S lua51-socket
Settings
--------
All settings are changed in `minetest.conf`. If any of these settings
are not set, the default value is used.
* `irc.server` (string, default "irc.freenode.net")
This is the IRC server the mod connects to.
* `irc.channel` (string, default "##mt-irc-mod")
The IRC channel to join.
* `irc.interval` (number, default 2.0)
This prevents the server from flooding. It should be at
least 2.0 but can be higher. After four messages this much
time must pass between folowing messages.
* `irc.nick` (string, default "MT-FFFFFF")
Nickname used as "proxy" for the in-game chat.
'F' stands for a random base-16 number.
* `irc.password` (string, default "")
Password to use when connecting to the server.
* `irc.NSPass` (string, default nil)
NickServ password. Don't use this if you use SASL authentication.
* `irc.sasl.pass` (string, default nil)
SASL password, same as nickserv password.
You should use this instead of NickServ authentication
if the server supports it.
* `irc.sasl.user` (string, default `irc.nick`)
The SASL username. This should normaly be set to your main NickServ account name.
* `irc.debug` (boolean, default false)
Whether to output debug information.
* `irc.disable_auto_connect` (boolean, default false)
If false, the bot is connected by default. If true, a player with
the 'irc_admin' privilege has to use the /irc_connect command to
connect to the server.
* `irc.disable_auto_join` (boolean, default false)
If false, players join the channel automatically upon entering the
game. If true, each user must manually use the /join command to
join the channel. In any case, the players may use the /part
command to opt-out of being in the channel.
* `irc.send_join_part` (boolean, default true)
Determines whether to send player join and part messages to the channel.
Usage
-----
Once the game is connected to the IRC channel, chatting using the 'T' or
F10 hotkeys will send the messages to the channel, and will be visible
by anyone. Also, when someone sends a message to the channel, that text
will be visible in-game.
Messages that begin with `[off]` from in-game or IRC are not sent to the
other side.
This mod also adds a few chat commands:
* `/irc_msg <nick> <message>`
Sends a private message to a IRC user.
* `/join`
Join the IRC chat.
* `/part`
Part the IRC chat.
* `/irc_connect`
Connect the bot manually to the IRC network.
* `/irc_disconnect`
Disconnect the bot manually from the IRC network (this does not
shutdown the game).
* `/irc_reconnect`
Equivilant to `/irc_disconnect` followed by `/irc_connect`.
You can also send private messages from IRC to in-game players.
To do it, you must send a private message to the bot (set with
the `irc.nick` option above), in the following format:
@playername message
For example, if there's a player named `mtuser`, you can send him/her
a private message from IRC with:
/msg server_nick @mtuser Hello!
To avoid possible misunderstandings (since all in-game players use the
same IRC user to converse with you), the "proxy" user will reject any
private messages that are not in that format, and will send back a
nice reminder as a private message.
The bot also supports some basic commands, which are invoked by sending
a private message to it. Use `!list` to get a list of commands, and
`!help <command>` to get help about a specific command.
Thanks
------
I'd like to thank the users who supported this mod both on the Minetest
Forums and on the #minetest channel. In no particular order:
0gb.us, ShadowNinja, Shaun/kizeren, RAPHAEL, DARGON, Calinou, Exio,

OldCoder, RealBadAngel, and all the people who commented in the
forum topic. Thanks to you all!
