Concatenate parameters and string

Hello there. This code should report who cast the buff, which buff cast, and who received it

Lua Code:

local f = CreateFrame("Frame")
f:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED")
f:SetScript("OnEvent", function(self, event, arg1, arg2, arg3, arg4, arg5, arg6, arg7, arg8, arg9, arg10, 
                                              arg11, arg12, arg13)
    if (event == "COMBAT_LOG_EVENT_UNFILTERED") then 
        if (arg2 == "SPELL_AURA_APPLIED") then --do stuffs
                end
    end
end)

What exactly do I have to write in order to get a sentence in the form "arg4 cast arg10 on arg7"?

Depends but the simplest just see it in your chat frame would be:

Lua Code:

if (arg2 == "SPELL_AURA_APPLIED") then --do stuffs
        print(arg4, "cast", arg10, "on", arg7)
end

You could use concatination:

Code:

print(arg4.."cast"..arg10.."on"..arg7)

or string format (%s is replaced with strings, see this for other replacment values:

Code:

local msg = "%s cast %s on %s"

print(string.format(msg, arg4, arg10, arg7))

or ...

The last two are useful if you are using something other than print() (like sending to the chat system)

Also since BfA, CLEU doesn't send its payload to the event handler anymore. You need to use CombatLogGetCurrentEventInfo() to query the args now.
