vwowrla/VWoWRLAHelper/matchers.lua

-- these patterns copied from the full set of combat log regex patterns located in 
-- the server app code under vwowrla.core.events.matchers/regex-matchers and 
-- "dumbed-down" / converted to lua patterns. lua patterns are not as complex as regular 
-- expressions, so there's a bit more repetition to get around things like missing support
-- for optional substring matching (e.g. "(hits|crits)", "(?:missed|misses)", etc ...).

-- event types have been "compacted" somewhat. we only care about types of events in a
-- fairly broad sense and don't need to be really, really specific.

-- additionally, for the purposes of this addon, there are some bits of info in certain
-- more complicated combat log strings that we don't care about and so support for matching
-- them has just been dropped out of the appropriate patterns. things such as glancing/crushing
-- blows and partial absorbs/resists... all we are using these matchers for is to correctly
-- parse out 1) the type of event, 2) the names of the entities involved, and finally 3) the
-- name of any skill being used by the source on a target.
