Passing events to tag functions

[Rainrider]

Currently a tag function receives two arguments: the unit and the realUnit (if self.overrideUnit is set) the tag is registered for. Is there a way to add the event the tag is being updated upon to the list of arguments?

It could be added as global in the tag functions environment, but is it really necessary?

I've encountered a situation where UnitClass returns nil when people join a party. I update the tag at UNIT_NAME_UPDATE, UNIT_FACTION and UNIT_CONNECTION and would like to know when this is the case. Apart from that one could further customize tags based on what event fired.

Would you give me some pointers how to add this as I must admit I barely understand the tags element.

I don't really see how it would help, but something simple like this should work:

diff --git a/elements/tags.lua b/elements/tags.lua
index 9826269..76e8c2d 100644
--- a/elements/tags.lua
+++ b/elements/tags.lua
@@ -416,11 +416,14 @@ local frame = CreateFrame"Frame"
 frame:SetScript('OnEvent', function(self, event, unit)
        local strings = events[event]
        if(strings) then
+               _ENV.event = event
                for k, fontstring in next, strings do
                        if(fontstring:IsVisible() and (unitlessEvents[event] or fontstring.parent.unit == unit)) then
                                fontstring:UpdateTag()
                        end
                end
+       else
+               _ENV.event = nil
        end
 end)

Then you can access the event by just checking: if event == "EVENT_NAME" then ... end

Thank you for that, haste. I'll have a look into my code as the powerbars of the party frames color correctly by class but my name tags don't. It's pretty seldom though and I don't have a sure path to reproduce it, that's why I wanted to have the event.

local f = CreateFrame("Frame")
f:RegisterEvent("UNIT_NAME_UPDATE")
f:RegisterEvent("UNIT_FACTION")
f:RegisterEvent("UNIT_CONNECTION")
f:SetScript("OnEvent", function(f, event, unit)
    if not UnitClass(unit) then
        print("UnitClass returned nil for", unit, "on", event)
    end
end)

Leave that running in the background for a while and see what it says.
