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.
