Addon that automatically whispers people when they join group.

[Dimmulux]

I am looking for an add-on that automatically whispers people a preset message when they join my group.

The use of the add-on would be to inform people of what the group is for (in case they've made a mistake) and provide relevant information (such as voice server details). It would be very helpful for this to be done automatically so that the leader can spend more time organising the group or LFMing.

Does anyone know of an add-on that has this feature? If no such addon exists, would anyone want to create it?

Note: this was initially posted at http://eu.battle.net/wow/en/forum/topic/9051726863 . I have still not found a solution since I posted there and it was suggested I try asking here.

If you don't find an add-on that does this, this might be a nice addition to an add-on I have

I don't think an addon like this exists.

I thought this would be a lot simpler to implement, but then I was reminded about cross-realm and all the issues that brings. I wrote something up that might work:

-- Add SHARPARAM_GROUP_WHISPER to SavedVariables to persist the settings
SHARPARAM_GROUP_WHISPER = SHARPARAM_GROUP_WHISPER or {}
 
local opt = SHARPARAM_GROUP_WHISPER
 
opt.enabled = true
op*****ssage = op*****ssage or "Welcome to the group!"
 
local members = {}
 
local PARTY_UNITS = {
    "party1",
    "party2",
    "party3",
    "party4",
    "party5"
}
 
-- Helper function to get a list of group members
local function getGroupMembers()
    local result = {}
    if IsInRaid() then
        for i = 1, GetNumGroupMembers() do
            local name = GetRaidRosterInfo(i)
            if not name:match("%w+-%w+") then
                -- Try to get realm from UnitName func
                local _, realm = UnitName(name)
                -- Fall back to using player realm
                if not realm then realm = GetRealmName() end
                name = ("%s-%s"):format(name, realm)
            end
            result[#result + 1] = name
        end
    else
        for _, unit in pairs(PARTY_UNITS) do
            local name, realm = UnitName(unit)
            if not realm then realm = GetRealmName() end
            result[#result + 1] = ("%s-%s"):format(name, realm)
        end
    end
    return result
end
 
-- Loop through members and message anyone new to the group
local function updateMembers()
    if not opt.enabled or not IsInGroup() or not UnitIsGroupLeader("player") then
        wipe(members)
        return
    end
   
    for _, v in pairs(getGroupMembers()) do
        -- New member? Great! Let's message them
        if not members[name] then
            sendMessage(name)
            -- Add them to list so they don't get messaged again
            members[name] = true
        end
    end
end
 
-- Gets the full player name string (name-realm) of the current player
local function getFullPlayerName()
    local name, realm = UnitName("player")
    if not realm then realm = GetRealmName() end
    return ("%s-%s"):format(name, realm)
end
 
local function sendMessage(name, realm) -- realm param currently unused
    realm = realm or GetRealmName()
    if not name:match("%w+-%w+") then
        name = ("%s-%s"):format(name:match("%w+"), realm)
    end
    if name == getFullPlayerName() then return end
    SendChatMessage(op*****ssage, "WHISPER", nil, name)
end
 
local frame = CreateFrame("Frame")
 
frame:SetScript("OnEvent", function(self, event, ...)
    updateMembers()
end)
 
frame:RegisterEvent("GROUP_JOINED")
frame:RegisterEvent("GROUP_ROSTER_UPDATE")
frame:RegisterEvent("INSTANCE_GROUP_SIZE_CHANGED")
frame:RegisterEvent("PARTY_MEMBERS_CHANGED")
frame:RegisterEvent("RAID_ROSTER_UPDATE")
 
SLASH_SHARPARAMGROUPWHISPER1 = "/sharpgw"
 
SlashCmdList["SHARPARAMGROUPWHISPER"] = function(e, msg)
    local cmd, arg = msg:match("(%w)%w*(.*)")
    if cmd == "t" then -- toggle
        opt.enabled = not opt.enabled
        print("Group whisper is now " .. (opt.enabled and "enabled" or "disabled"))
    elseif cmd == "m" then -- set message
        -- dirty workaround to skip the first space
        op*****ssage = arg:gsub("^ ", "")
        print("Update group whisper message!")
    end
end

PLEASE NOTE: I am not sure if this code will work with player names using unicode characters.

Is wipe() a standard function? Never heared of it.

It's a function in the WoW API to clear a table's values. I believe it's not available in standard Lua.
