At least currently in 8.2

Combat log events occur a lot more frequentrly than UNIT_HEALTH
This library tracks incoming healing and damage and adjusts health values.
As a result you can see health updates sooner and more often.

This implementation is safe and accurate.
For each unit we keep history of health values after each change from combat log.
When UNIT_HEALTH arrives, UnitHealth value is searched in this log.
If it's found, then chain is valid, and library proceeds to return latest value from it.
If not it falls back onto UnitHealth value. If UnitHealth values in the next 1.4 seconds
also could not be found to re-validate combat log chain,
then it is reset with current UnitHealth value as a starting point.

Why it's like that and not simpler

UNIT_HEALTH and CLEU are asynchronous, UNIT_AURA throttles and usually is slower,
but sometimes it comes first, and with CLEU immediately after it, double damage/healing
occurs. I'm avoiding that, keeping them separate
and only checking whether combat log value has deviated from UnitHealth.


Afaik this new event, that was introduced in 5.0, still throttles damage, but not heals.
Or at least it doesn't mash up heals with damage.
In short, if you just listen to both UNIT_HEALTH and UNIT_HEALTH_FREQUENT,
that's a decent compromise.


local f = CreateFrame("Frame") -- your addon
local LibCLHealth = LibStub("LibCLHealth-1.0")
if LibCLHealth then
    LibCLHealth.RegisterCallback(f, "COMBAT_LOG_HEALTH", function(event, unit, eventType)
        local health = LibCLHealth.UnitHealth(unit)
        print(event, unit, health)

eventType – either nil when event comes from combat log, or "UNIT_AURA" to indicate
events that can carry update to death/ghost states.
