Need help with this LUA script, please.

[Eliteplague]

I want to add "Every Man for Himself" to this script, basically I wanted it to cast that whenever my character is stunned, feared, or hexed. What would be the correct LUA format?

/run if UnitHealth("player")/UnitHealthMax("player")<0.10 and GetSpellCooldown("Divine Shield")==0 and IsUsableSpell("Divine Shield") then CastSpellByName("Divine Shield") end;
/run if GetSpellCooldown("Divine Plea") ==0 and UnitPower("player")/UnitPowerMax("player")<=0.10 then CastSpellByName("Divine Plea") end;
/run f=0; if UnitExists("focus") then for i=1,40 do d={UnitBuff("focus",i)}; if d~=nil and d[1]=="Beacon of Light" and d[8]=="player" and d[7]-GetTime()>=3 then f=1; break end end if f==0 then RunMacroText("/cast [@focus] Beacon of Light") end end;
/run FoL=3000; HS=6000; HL=8000; t="raid"; nps=1; npe=GetNumRaidMembers(); if npe==0 then t="party"; nps=0; npe=GetNumPartyMembers() end; e=UnitExists; n=UnitName; h=UnitHealth; hm=UnitHealthMax; s=nil; f="focus"; fh=0; if e(f) then fh=hm(f)-h(f) end; m=0; w=f; for i=nps,npe do if i==0 then tt="player" else tt=t..i end; if e(tt) and (e(f)==nil or n(tt)~=n(f)) then a=hm(tt)-h(tt); if a>m and UnitInRange(tt)==1 and UnitIsDeadOrGhost(tt)~=1 then m=a w=tt end end end; if fh>2*m then m=fh end; if GetSpellCooldown("Holy Shock")==0 and m>=HS then s="Holy Shock" elseif m>=HL then s="Holy Light" elseif m>=FoL then s="Flash of Light" end; if s~=nil then RunMacroText("/cast [@"..w.."] "..s) end;
/run if GetSpellCooldown("Judgement of Light") == 0 then RunMacroText("/cast [@focustarget] Judgement of Light") end;
/run f=0; if UnitExists("focus") then for i=1,40 do d={UnitBuff("focus",i)}; if d~=nil and d[1]=="Sacred Shield" and d[8]=="player" and d[7]-GetTime()>=3 then f=1; break end end if f==0 then RunMacroText("/cast [@focus] Sacred Shield") end end;
/run t="raid"; nps=1; npe=GetNumRaidMembers(); if npe==0 then t="party"; nps=0; npe=GetNumPartyMembers() end; w=nil; m=0; for i=nps,npe do if i==0 then tt="player" else tt=t..i end; if UnitExists(tt) and UnitInRange(tt)==1 and UnitIsDeadOrGhost(tt)~=1 then for j=1,40 do d={UnitDebuff(tt,j)}; if d~=nil and (d[5]=="Magic" or d[5]=="Poison" or d[5]=="Disease") and d[7]>m then w=tt; m=d[7] end end end end; if w~=nil then RunMacroText("/cast [@"..w.."] Cleanse") end;
/run StaticPopup_Hide("MACRO_ACTION_FORBIDDEN");

You could check stuns/cc by name/id then cast every man for himself:

if UnitDebuff("player", "buffName") then
     CastSpellByName("every man for himself")
end

untested but should be close

Didn't work. I tried

/run if UnitDebuff("player","Polymorph" then
CastSpellByName("Every Man for Himself") end

I think there is more to it.

I tried

if UnitDebuff("player","Weakened Soul") then
print("debuff!")
end

Should work for any debuff, replace the print by your trinket, should be ok.

/run if UnitDebuff("player","Polymorph"") then
Every Man for Himself("debuff!")
end

Did not work, thanks for trying to help though.

Every Man for Himself("debuff!")

Hum, really? x)

if UnitDebuff("player","Polymorph") then
CastSpellByName("Every Man for Himself") 
end

This IS working but you should use it in ONE line...
And use /script not /run:

/script if UnitDebuff("player","Weakened Soul") then CastSpellByName("Every Man for Himself") end

or

/script if UnitDebuff("player","Weakened Soul") then print("debuff!") end

Use this one for testing.

/script and /run are synonymous. Why not use the shorter 'run'?
