  Healers Assist by Kiki - European Cho'gall


/* ********************************************** 
**  Features :
********************************************** */
  The addon is splitted in two main parts : Healers View, and Emergency View
    - Healers view (only shows healers in your group/raid AND in the same channel) :
      - You can configure how many healers you want to see in the list (from 1 to 16)
        -> You can collapse the whole list with a small checkbox above the list (collapse = 1 healer in the list)
      - Current mana bar in blue
      - Cooldown of some spells (Divine intervention, Divine Shield, Innervate, Rebirth, Lightwell, Reincarnation)
      - Healer that received one of the previous cooldown spells blinking in red
      - Current spell the healer is casting with progression bar, and an estimation of the incoming heal value (computed using +heal bonuses, talents, and blessing of light)
      - Current target for spell with health bar in green
        -> Name of the target will scale from white to red, depending on how much your spell will overheal (red=100% overheal, white=0%)
      - Short name of the spell, or spell failed reason if the cast failed
      - When a spell cast completed, the healed value is shown (with a "C:" if the spell has crit)
    - Emergency view (almost like CTRaid emergency monitor)
      - You can configure how many targets you want to see in the list (from 0 to 6) -> Set it to 0 to fully hide the emergency list
      - Targets that need to be healed, with name class-colored, and health bar in green (with missing HP or current health% if target out-of-raid or NPC)
        -> Target name is shown in blue, if you are currently casting a spell on him
      - Count of healers currently casting on this target
      - Estimated incoming heal value (summ of all estimated heal on this target)
      - Possibility to filter by groups and/or classes (configured in the options)
      - You can clic a target to select it, or if you have CastParty installed, it will use Castparty buttons modifier

  There are two sorting modes for the healers view, but you are always the first in the list :
    - By casting order
      1) First are healers with the same target than you
      2) Then healers who's spell completed
      3) Then healers who's spell will complete before the others
    - By alphabetic order
  You can change the sorting mode, by clicking on a column title :
    - Clicking on "Healer's name column title" will sort using alphabetic order
    - Clicking on any other column title will sort using Casting order

  The emergency view is sorted like this :
    - Players with less life (sorted by percentage), BUT if someone is casting on him the estimated heal value is added to it's current health
      -> Someone with 10% life but +20% health incoming, will not show before someone with 20% life and no incoming heal.

  If you click on a cooldown spell that is ready and castable on others (innervate/rebirth/divine intervention), you will send a request for this spell to it's owner.
  The owner of the spell can :
    - Automatically refuse all requests for this spell (configured in the options)
    - Automatically accept requests from trusted healers (configured in the options - Configuration NOT YET AVAILABLE)
    - Otherwise, a popup window with Accept/Cancel will be displayed, asking for auto-cast of the spell on who
  If the owner automatically accepts this spell or clicked on the Accept button, the spell is directly casted on you
  
  You can now request a spell, even if you don't have Healers Assist installed !
  All you have to do is write a macro with inside :
    /script SendAddonMessage("HealAss","<HA7>09"..'\30'.."16"..'\30'.."Kiki","RAID")
  You just have to replace "Kiki" by the name of the player you want to request a spell (WARNING, Case sensitive !!), and change the SpellCode (the "16" value) according to :
   - Innervate : 16
   - Rebirth : 17
   - Divine Intervention : 81
   - Blessing of Protection : 87
   - Mana Tide Totem : 63
   - Light Well : 48
   - Power Infusion : 50

  The main window can be automatically opened when you are in a group/raid (configured in the options)
  You can assign a key to "open main window" and "open options window", from the Shortcut menu

  By clicking the "Rest" checkbox (topleft of the window), you notify other healers that you enter a mana regen cycle. While you stay in this mode, your mana bar will be flashing in the Healers list.
  You'll leave this mode (and informing other healers) :
    - If you uncheck the box
    - If you start casting a spell
    - If your mana bar is full


/* ********************************************** 
**  Known bugs :
********************************************** */


/* ********************************************** 
**  Thanks :
********************************************** */

  Thanks to Margouline for the initial idea (seing who is casting a spell on the MainTank)
  Thanks to all cobaye healers of my guild (Mainly Margouline, Kathrynn, Phalytcha, Aïneken, Koblar, Sainte, Siko, Bonhass, Gonzilla, Pitichat and all other ^^)
  Thanks to Artack for some code ripped from SWStats
  Thanks to Freddy for so many little code details and functions, and 'DE' localization, and so many great HA plugins
  Thanks to Decursive guys, for range checking code


/* ********************************************** 
**  Detecting HA from another addon :
********************************************** */
If you need to detect if Healers Assist is present from another addon, I suggest you test the presence of the variable HA_VERSION (a string)


/* ********************************************** 
**  Overriding default frame OnClick function :
********************************************** */
This is automatically done by HA if it detects CastParty or WatchDog (clicks are forwarded to either one of them).
If you want to change the default behaviour, you have to initialiaze the "HA_CustomOnClickFunction" variable to a function of the following prototype
  bool CallbackFunction(string ButtonEvent,string UnitID)
    - ButtonEvent is the button event that triggered the callback ("LeftButtonDown", "RightButtonDown", ...)
    - UnitID is the unit id the click applies to ("player", "party1", "raid25", ...)
    - The function must return a boolean value : True if it has processed the message, False otherwise


/* ********************************************** 
**  Macro API :
********************************************** */
Command to select an emergency target :
---------------------------------------
 HA_SelectEmergency(pos)
  "pos" is the index (from 1 to 6, 1 being the highest priority)

Command to enter/leave regen mode :
-----------------------------------
 HA_SetRegenMode(state)
  "state" is either true (enter regen) or false (leave regen)



/* ********************************************** 
**  Plugins API :
********************************************** */

Plugin Entry points :
---------------------

OnSpellStart(healer,raider,SpellCode,SpellName,CastTime,Estimated,WillCrit,SpellRank)
OnSpellDelayed(healer,Value)
OnSpellHit(healer,raider,SpellCode,SpellName,Value,Crit,OverHealed,InstantSpell)
OnSpellHitInstant(healer,raider,SpellCode,SpellName,Duration,Estimated,SpellRank)
OnSpellFailed(healer,raider,SpellCode,IReason,Reason)
OnSpellHotTick(healer,raider,SpellCode,SpellName,Value,OverHealed)
OnEatHot(SpellCode,raider,HotFrom,HotStartTime,HotDuration) (HotStartTime was initialized using GetTime() function)
OnSpellCooldown(healer,raider,SpellCode,SpellName)
OnCooldownUpdate(healer,SpellCode,SpellName,Cooldown)

OnEvent(event,params)
OnGetHealersList
SortHealers
OnGetEmergencyList
SortEmergency

-----------------

Notes :
 - Don't rely on HA_Healers[HA_PlayerName] infos in the OnSpellHitInstant function, since it might not be initialized with correct values if instants are not activated in HA's config

Sending private plugin message between player :
-----------------------------------------------
A plugin that want to exchange data between players, must register the Plugin.OnPluginMessage function which prototypes :
 function OnPluginMessage(From,Params)
   - From       : String - Name of the player who sent the message
   - Params[1]  : String - Plugin name
   - Params[..] : Any    - Passed parameters

To send data to other players who have the plugin installed, it must call
 function HA_COM_PluginCommand(PluginName,...)
   - PluginName : String - Name of the plugin (same value as Plugin.Name)
   - ...        : Any    - Passed parameters


Using plugin to populate and/or sort Healers and/or Emergency list :
--------------------------------------------------------------------
You have the possibility to override both displayed rows and the way rows are sorted, for the Healers list (top one), and the Emergency list (bottom one).

1) Populate Healers list
 You must add the 'OnGetHealersList' hook to your plugin struct.
 This function takes no parameter, but must return a list of healers.
 This list must be populated using the table.insert() function, and each entry must contain a HA_Healers struct.
 If you want to use HA's default filter (that uses current configuration to filter classes), you can call the HA_DefaultFilter_Healer() function which takes a HA_Healers struct as parameter, and returns true ou false (true = Healer NOT filtered).
 If you don't use default filter function, you must AT LEAST check if HA_Healers[].Raider is nil (if nil, must NOT be added to the list)
 Example :
    local list = {};
    for name,tab in HA_Healers
    do
      if(HA_DefaultFilter_Healer(tab))
      then
        tinsert(list, tab);
      end
    end
    return list;

2) Custom sorting of Healers list
 You must add the 'SortHealers' hook to your plugin struct.
 This function is directly passed to the table.sort() function (see doc of table.sort) to sort the healers list. Either default one, or the one returned by 1).

3) Populate Emergency list
 You must add the 'OnGetEmergencyList' hook to your plugin struct.
 This function takes no parameter, but must return a list of raiders.
 This list must be populated using the table.insert() function, and each entry must contain a struct of :
  {
    raider -- A HA_Raiders struct
    total -- Total incoming heals. Must be computed using the HA_ComputeIncomingHeals function (takes a HA_Raiders struct as parameter, and returns the total incoming heal value)
  }
 If you want to use HA's default filter (that uses current configuration to filter classes, groups, range...), you can call the HA_DefaultFilter_Raider() function which takes a HA_Raiders struct as parameter, and returns true ou false (true = Raider NOT filtered).
 Example :
    local list = {};
    for name,tab in HA_Raiders
    do
      if(HA_DefaultFilter_Raider(tab))
      then
        total = HA_ComputeIncomingHeals(tab);
        tinsert(list, { raider = tab; total = total });
      end
    end
    return list;

4) Custom sorting of Emergency list
 You must add the 'SortEmergency' hook to your plugin struct.
 This function is directly passed to the table.sort() function (see doc of table.sort) to sort the emergency list. Either default one, or the one returned by 3).
