+
+--[[ libcast ]]--
+-- A pfUI library that detects and saves all ongoing castbars of players, NPCs and enemies.
+-- The library also includes spells that usually don't have a castbar like Multi-Shot and Aimed Shot.
+-- This is exclusivly used for vanilla in order to provide pfGetChannelInfo and pfGetCastInfo functions.
+--
+-- External functions:
+--   pfGetChannelInfo(unit)
+--     Returns information on the spell currently cast by the specified unit.
+--     Returns nil if no spell is being cast.
+--
+--     cast[String] - The name of the spell, or nil if no spell is being cast.
+--     nameSubtext[String] - (DUMMY) The string describing the rank of the spell, e.g. "Rank 1".
+--     text[String] - The name to be displayed.
+--     texture[String] - The texture path associated with the spell.
+--     startTime[Number] - Specifies when casting has begun, in milliseconds.
+--     endTime[Number] - Specifies when casting will end, in milliseconds.
+--     isTradeSkill[Boolean] - (DUMMY) Specifies if the cast is a tradeskill
+--
+--   pfGetCastInfo(unit)
+--     Returns information on the spell currently channeled by the specified unit.
+--     Returns nil if no spell is being channeled.
+--
+--     cast[String] - The name of the spell, or nil if no spell is being cast.
+--     nameSubtext[String] - (DUMMY) The string describing the rank of the spell, e.g. "Rank 1".
+--     text[String] - The name to be displayed.
+--     texture[String] - The texture path associated with the spell.
+--     startTime[Number] - Specifies when casting has begun, in milliseconds.
+--     endTime[Number] - Specifies when casting will end, in milliseconds.
+--     isTradeSkill[Boolean] - (DUMMY) Specifies if the cast is a tradeskill
+--
+-- Internal functions:
+--   libcast:AddAction(mob, spell, channel)
+--     Adds a spell to the database by using pfUI's spell database
+--     to obtain durations and icons
+--
+--   libcast:RemoveAction(mob, spell)
+--     Removes the castbar of a given mob, if `spell` is an interrupt.
+--     spell can be set to "INTERRUPT" to force remove an action.
+--
+
+-- return instantly if we're not on a vanilla client
+if pfUI.client > 11200 then return end
+
+-- return instantly when another libcast is already active
+if pfUI.api.libcast then return end
