### Create and Manage Auction House Tabs with LibAHTab

Source: https://github.com/themousenest/auctionator/blob/master/Libs_ModernAH/LibAHTab/README.md

This snippet demonstrates how to initialize LibAHTab, listen for the Auction House interaction event, and register a custom tab. It also outlines the primary API methods for checking existence, retrieving buttons, and programmatically selecting tabs.

```lua
local LibAHTab = LibStub("LibAHTab-1-0")
local frame = CreateFrame("Frame")
local UNIQUE_TAB_ID = "My id"

frame:RegisterEvent("PLAYER_INTERACTION_MANAGER_FRAME_SHOW")

frame:SetScript("OnEvent", function(_, eventName, panelType)
  if eventName == "PLAYER_INTERACTION_MANAGER_FRAME_SHOW" and panelType == Enum.PlayerInteractionType.Auctioneer then
    local attachedFrame = CreateFrame("Frame")
    attachedFrame:SetScript("OnShow", function()
      -- do something when the tab is selected
    end)
    LibAHTab:CreateTab(UNIQUE_TAB_ID, attachedFrame, "Tab text")
  end
end)

-- API
LibAHTab:CreateTab(UNIQUE_TAB_ID, attachedFrame, "Tab Button Text", "Optional tab header")
LibAHTab:DoesIDExist(UNIQUE_TAB_ID)
LibAHTab:GetButton(UNIQUE_TAB_ID)
LibAHTab:SetSelected(UNIQUE_TAB_ID)
```

### Add Double Line to Battle Pet Tooltip (Lua)

Source: https://github.com/themousenest/auctionator/blob/master/Libs_ModernAH/LibBattlePetTooltipLine/README.md

Demonstrates how to use the LibBattlePetTooltipLine library to add a double-line with custom text and color to a battle pet tooltip. It utilizes `hooksecurefunc` to modify the `BattlePetToolTip_Show` function. The `AddDoubleLine` function takes the tooltip object, left-aligned text, and right-aligned text as arguments.

```lua
local LibBattlePetTooltipLine = LibStub("LibBattlePetTooltipLine-1-0")

hooksecurefunc("BattlePetToolTip_Show", function(...)
  LibBattlePetTooltipLine:AddDoubleLine(BattlePetTooltip, "Special Detail",
RED_FONT_COLOR:WrapTextInColorCode("Me"))
end)
```

```lua
Auctionator.API.v1.MultiSearch("MyAddon", {"Item1", "Item2"})

Auctionator.API.v1.RegisterForDBUpdate("MyAddon", function()
  print("Database updated!")
end)
```

-- Returns the price in coppers, or nil if one wasn't found
Auctionator.API.v1.GetAuctionPriceByItemID(callerID, itemID)

-- Returns the last scanned price for an item identified by itemLink
-- Returns the price in coppers, or nil if one wasn't found
Auctionator.API.v1.GetAuctionPriceByItemLink(callerID, itemLink)
