Lua: auto invite to +i channels

[M_D_K]

Need xchat and the lua plugin for it

Code: Select all

--Author: M_D_K
local script_name = "auto_invite.lua"
local script_desc = "Author: M_D_K|Automatically invite you to channels that are invite only (you need to be on the access list though)"
local script_ver = "1.0"

--store channels we're waiting an invite for
wait_list = {}

function find(needle, haystack)
	if haystack == nil or needle == nil then
		return false, -1;
	end

	for k, v in pairs(haystack) do
		if v == needle then
			return true, k
		end
	end
	return false, -1
end

function safe_invite(channels)
	--run through every index in channels check if we're already waiting and insert if not
	--really horrible performance on large data sets
	for k, v in pairs(channels) do
		local present, loc = find(v, wait_list)
		if not present then
			table.insert(wait_list, v)
			xchat.commandf("msg ChanServ invite %s", v)
		end
	end
end

function handle(word, word_eol)
	if #word < 2 then
		return xchat.EAT_ALL
	end

	local chans = word
	table.remove(chans, 1) --eat the first entry (always "ajoin")
	safe_invite(chans)

	return xchat.EAT_ALL
end

--gets called every time there is an invited event
--looks like this:
--	You have been invited to #channel by someone (network)
function invite(word)
	local present, loc = find(word[1], wait_list)
	if present then
		table.remove(wait_list, loc)
		xchat.commandf("join %s", word[1])
	end
	return xchat.EAT_NONE
end

function xchat_register()
	return script_name, script_desc, script_ver;
end

function xchat_init()
	xchat.hook_command("ajoin", "handle", xchat.PRI_NORM, "Usage: AJOIN <channel>");
	xchat.hook_print("Invited", "invite", xchat.PRI_NORM);
end
