Macros

Hi all. Is it posible to make macro that If i have a target it would clense it, if not it would target nearest friendly target and clense it and if I'am holding ALT it would clense me ?

no its not posible

What you are asking is what is called an illegal macro and there is no way of doing it.

You can however use a mouseover and your brain.

#showtooltip Purify Spirit
/cast [nomod,target=mouseover,help] Purify Spirit; [nomod,help] Purify Spirit;
/cast [mod:alt,target=player] Purify Spirit;

I mean you could try:

#showtooltip Purify Spirit
/cast [nomod,help] !Purify Spirit;
/targetfriendplayer
/cast Purify Spirit
/targetlasttarget
/cast [mod:alt,target=player] Purify Spirit;

But I doubt its going to work the way you wish.
