I made a macro to share current player location using the new map pins, thought i’d share it. not really sure if it can be made any smaller.
/run map=C_Map.GetBestMapForUnit("player");posi=C_Map.GetPlayerMapPosition(map,"player");C_Map.SetUserWaypoint(UiMapPoint.CreateFromCoordinates(map,posi:GetXY()));SendChatMessage(format("Chest at %s",C_Map.GetUserWaypointHyperlink()),"CHANNEL",nil,1)
last i checked, that doesn’t utilize the new map pins
No, it does not.
What would you do if you wanted it to announce your targets name instead of “chest”
“Rustfeather up at - Map”
for mobs
/run m=C_Map.GetBestMapForUnit("player");p=C_Map.GetPlayerMapPosition(m,"player");C_Map.SetUserWaypoint(UiMapPoint.CreateFromCoordinates(m,p:GetXY()));SendChatMessage(format("%s: %s",UnitName("target"),C_Map.GetUserWaypointHyperlink()),"CHANNEL",nil,1)
I made it smaller, and also managed to fit in health percentages
/run local c,p,t,m=C_Map,"player","target"m=c.GetBestMapForUnit(p)c.SetUserWaypoint{uiMapID=m,position=c.GetPlayerMapPosition(m,p)}SendChatMessage(format("%%t (%d%%)%s",UnitHealth(t)/UnitHealthMax(t)*100,c.GetUserWaypointHyperlink()),"CHANNEL",nil,1)
The macro works great and I love it.
There is 1 weird thing that I am not sure if it is a feature or a byproduct, but when your target is a rare it says
{rt3}Arachnoid Harvester (96%)[ Map Pin Location]
I don’t mind the “{rt3}” part and will be using the macro regardless. I assume you would appreciate the report on it thought.
I didn’t know that the %t substitution would also show the raid target, that’s a nice feature I suppose, thanks for telling. We can’t remove it with just UnitName() since then it would be too big for the macro 
Is that what that means? So it is doing it because another addons marks it with a skull.
I was wrecking my mind trying to figure out what that meant
It’s just Blizzard adding that in, I guess a very handy feature when people want to announce they just sheeped a mob marked with a raid target which makes it more noticeable
Unless you mean why it was marked, then another addon or player already marked your target with e.g. a skull yea
It is my rare tracker marking it.
My only actual question was more of a statement “oohhh the rt3 is there because I have it marked”
I legit couldn’t figure out why it was putting that there. My best guess was it identifying it as a rare elite and that somehow bleeding over to the %t
mmm I misunderstood 
I’d like to post the coordinates in chat as well. I have a macro extender so im not limited to 255 characters. I tried the following:
/run local c,p,t,m=C_Map,“player”,“target"m=c.GetBestMapForUnit§c.SetUserWaypoint{uiMapID=m,position=c.GetPlayerMapPosition(m,p)}SendChatMessage(format(”%%t is up at %d,%d (%d%%)%s",UnitHealth(t)/UnitHealthMax(t)*100,c.GetUserWaypointHyperlink()),“CHANNEL”,nil,1)
Also, is it possible to use the target’s location instead of the player’s?
/run local c,p,t,m,q=C_Map,"player","target"m=c.GetBestMapForUnit(p)q=c.GetPlayerMapPosition(m,p)c.SetUserWaypoint{uiMapID=m,position=q}SendChatMessage(format("%%t is up at [%.1f, %.1f] (%d%%)%s",q.x*100, q.y*100,UnitHealth(t)/UnitHealthMax(t)*100,c.GetUserWaypointHyperlink()),"CHANNEL",nil,1)

There is UnitPosition() which can be transformed to uimap coords, but it also only works on players so not possible 
THANK YOU for the solution and explanation. Your assistance makes this game way more enjoyable!
If i ran wow i’d make sure contributors such as yourself were rewarded with free subscriptions, a special in-game title, and maybe even given priority in queues. #Recognize
Thanks to this thread and Kibit’s code, Macro-Talk’s added map pins as a substitution, %wp
/stopmacro [noexists]
/1 %T %Thp - %sz (%loc) %wp
Name HP% - SubZone (coords) [Map Pin]
That’s great! Ty for the info.
I’m always surprised when i see a top ten addon list that doesn’t mention Macro-Talk.
