"Calling out" Macro issue.

[Deleted]

Hello, I'm looking for some help with a macro of mine, since I havent found something that calls out my monk cds I've made macros instead, for example I have:
#showtooltip Life Cocoon
/stopcasting
/cast Life Cocoon
/ra Life Cocoon cast on %t!

I wonder if its possible to make the last line only occur once, since I sometimes spam click Life Cocoon and I dont want to over run the chat.

I also wonder if its possible to make Life Coccon clickable when its called out, like if I use Barkskin on my druid Fortexorcist calls it out with a clickable link.

Thanks in advance.

There you go:

#showtooltip
/run local s,_,u=116849,SecureCmdOptionParse("[@mouseover,help][@target]")if GetSpellCooldown(s)==0 and UnitInRange(u)then SendChatMessage(GetSpellLink(s).." -> "..UnitName(u),"RAID")end
/cast [@mouseover,help][]Life Cocoon

What it won't do:
Announce the cast when your target or mouseover target is not in raid.
Announce the cast on yourself when you don't have yourself as target or you don't mouseover yourself.
