-- BarVis. MIT, see LICENSE.
--
-- BarVis: set an EllesmereUI action bar to Show, Hide or Mouseover from a window, a
-- keybind or chat.
--
-- HOUSE RULE: Ace everywhere. If an Ace3 library does a job, use it; never hand-roll a
-- replacement or reach around it. One way to print (AceConsole), one settings table
-- (AceConfig), one message path (AceEvent), one completion path (AceTab), one db (AceDB).
--
-- Core: the addon object, the AceConfig app name, the saved settings, the key-binding
-- label and the login line. Nothing else. The work is in the modules under Modules\:
--   Modes      the three modes and their EllesmereUI values
--   Bridge     the only file that reads or writes EllesmereUI
--   Style      the chat colors
--   Options    the AceConfig table: window controls and the /barvis chat commands
--   Completion AceTab completion of the /barvis words
--   Window     opens, closes, toggles and refreshes the window (the keybind lands here)
--   Broker     the LibDataBroker launcher and the LibDBIcon minimap button
-- Saves only the minimap button state, in one account-wide profile. The bar settings
-- live in EllesmereUIActionBars' own profile.
