Vendor Search

Adds a search box to the vendor (merchant) window in WoW: Mists of Pandaria Classic. Typing filters the list of items for sale; pagination, prices, extended-cost currencies, tooltips, stack splitting and buying all keep working normally.

Install

Copy the VendorSearch folder into:

World of Warcraft\_classic_\Interface\AddOns\VendorSearch\

so that you end up with ...\AddOns\VendorSearch\VendorSearch.toc. Restart the client (or /reload) and enable it in the AddOns list.

Usage

• Open any vendor and type in the box at the top-right of the merchant window.
• Multiple words are ANDed: heavy leather matches items containing both.
• Esc clears the box; /vs <text> focuses it and pre-fills a search.
• The box hides on the Buyback tab.

How it works

Blizzard's MerchantFrame_UpdateMerchantInfo draws the page. For the duration of that one call, the merchant query API (GetMerchantNumItems, GetMerchantItemInfo, GetMerchantItemLink, cost/stack helpers) is swapped for wrappers that translate a filtered index into the real merchant index. The API is restored immediately after, and each item button's ID is re-pointed at its real merchant index — so every click path (buy, modified-click link, split stack, extended-cost confirmation) runs through unmodified Blizzard code with the correct index.

This avoids re-implementing the merchant layout, which is what usually breaks this kind of addon on a patch.

Tweaks

The search box has two placement presets, picked automatically at each vendor:

local PLACEMENT = {
	elvui   = { ..., x = -30, y = -18, width = 110, height = 18 },
	default = { ..., x = -40, y = -34, width = 130, height = 20 },
}

elvui is used only when ElvUI is loaded and its Blizzard-frame merchant skin is enabled (E.private.skins.blizzard.merchant) — that skin removes the portrait and pulls the item rows up, leaving very little header room. Otherwise the default preset drops the box into the empty band the stock frame has between its title bar and the first item row.

The check runs on every MERCHANT_SHOW, so toggling ElvUI profiles mid-session moves the box without a reload.

If MoP Classic moves past 5.5.x, bump ## Interface: in VendorSearch.toc.
