WoWInterface - target health percentage

i used to have an addon back in retail wrath and on private servers which showed status text in a neat way, i have the code here but it doesnt work with the classic client, does anyone know how to make it behave like intended?

i know theres an option to show percentage and status text in game but i dont like how its displayed

Code:

hooksecurefunc("TextStatusBar_UpdateTextString", function(textStatusBar)

        if textStatusBar == TargetFrameHealthBar and not GetCVarBool("statusTextPercentage") and not textStatusBar.showPercentage then

                local s = TargetFrameTextureFrameHealthBarText:GetText()

                if s then

                        s = string.match(s, "[^%/%(]+")

                        if s then

                                TargetFrameTextureFrameHealthBarText:SetText(s.."("..tostring(math.ceil((UnitHealth("target") / UnitHealthMax("target")) * 100)).."%)")

                        end

                end

        end

end)

this is how it looks like:

hooksecurefunc("TextStatusBar_UpdateTextStringWithValues",function(self,text,val,min,max)
    if self==TargetFrameHealthBar and max>0 and (val>0 or not self.zeroText) then
        if self.LeftText then self.LeftText:Hide(); end
        if self.RightText then self.RightText:Hide(); end
 
        text:SetFormattedText("%s (%d%%)",AbbreviateLargeNumbers(val),math.ceil(100*val/max));
        text:Show();
    end
end);
