Also, since I didn't want to redo all my existing routes, I did the following:

local function RefreshZoneNodes(zoneName)
   zoneName = zoneName or _G.SetMapToCurrentZone() or _G.GetRealZoneText()
   local continentId = Routes.LZName[zoneName][3]
   local zoneId = Routes.LZName[zoneName][4]

   for index, objectId, gType in _G.Gatherer.Storage.ZoneGatherNames( continentId, zoneId ) do
      local x, y = _G.Gatherer.Storage.GetGatherInfo(continentId, zoneId, objectId, gType, index)
      if x and y then
         local newCoord = Routes:getID(x, y)
         local nodeName = _G.Gatherer.Util.GetNodeName(objectId)
         Routes:InsertNode(zoneName, newCoord, nodeName)
      end
   end
end
source.RefreshZoneNodes = RefreshZoneNodes
-- /script Routes.plugins["Gatherer"].RefreshZoneNodes()

I use this to refresh the current zone or a particular zone by zone.

Here's a quick patch for Plugins\Gatherer.lua to get the nodes that are added to Gatherer after a route was first created. Just add the following code at the end:

local idToName = nil
if Gatherer and Gatherer.Api.AddGather then
   local origAddGather = Gatherer.Api.AddGather
   Gatherer.Api.AddGather = function(objectId, gatherType, indoorNode, gatherSource, gatherCoins, gatherLoot, wasGathered, gatherC, gatherZ, gatherX, gatherY, ...)
      -- Only add route for successful addition in Gatherer
      if origAddGather(objectId, gatherType, indoorNode, gatherSource, gatherCoins, gatherLoot, wasGathered, gatherC, gatherZ, gatherX, gatherY, ...) then
         -- When we do the gathering ourselves
         if not (gatherC and gatherZ and gatherX and gatherY) then
            gatherC, gatherZ, gatherX, gatherY = Gatherer.Util.GetPositionInCurrentZone()
         end

         local nodeName = Gatherer.Util.GetNodeName(objectId)
         local newCoord = Routes:getID(gatherX, gatherY)
         if not idToName then
            -- build the table to get the zone name from the continentId and the ZoneId
            idToName = {}
            for zoneName, zoneTable in pairs(Routes.LZName) do
               local continentId, zoneId = zoneTable[3], zoneTable[4]
               idToName[continentId] = idToName[continentId] or {}
               idToName[continentId][zoneId] = zoneName
            end
         end
         local zoneName = (idToName[gatherC] and idToName[gatherC][gatherZ]) or ""
         Routes:InsertNode(zoneName, newCoord, nodeName)
      end
   end
end

There is no API to remove node in Gatherer so I didn't anything for Routes:DeleteNode()

Quote from Xinhuan

That's correct, Gatherer does not have any method to inform other addons when it finds a new node. I've been talking to Esamynn on and off about it, he's interested in implementing something, but he's really busy.

Can you point me to the function that needs to be called in routes when an update occurs. Maybe I can hack something for new nodes on my local copy and pass it along if it's any good.

Re-optimizing do not add the newly discovered nodes and I'm using Gatherer so I guess I'm out of luck.

Hey guys, great addon. I'm very happy with the routes that are plotted for me.

Quick question: is there a way to refresh a route with new node data without deleting and recreating it?

TIA
