LUA code to detect message channel?

[Kujako]

Since they've changed how LFR, LFG, etc work, I am having a hard time detecting if I can use INSTANCE_CHAT, RAID_WARNING, RAID, PARTY message channels. Anyone have current code to handle this?

Old code is....

    if(IsInRaid()) then
        if(UnitIsGroupAssistant("player")) then
            msgChan="RAID_WARNING";
        else 
            msgChan = "RAID";
        end
    elseif(IsInGroup()) then
        if(IsInInstance()) then
            msgChan = "INSTANCE_CHAT";
        else
            msgChan = "PARTY";
        end
    else
        msgChan = "SAY";
    end

There are multiple ways to do this, and ever since INSTANCE_CHAT and HOME/INSTANCE were added things only got more confusing

Something like this could maybe work

msgChan = UnitIsGroupAssistant("player") and "RAID_WARNING" or IsPartyLFG() and "INSTANCE_CHAT" or IsInRaid() and "RAID" or IsInGroup() and "PARTY" or "SAY"
