Get spell name from a button name

Hello,

I'm looking to setup a script at load time to do the following:

Code:

local button = _G["BT4Button73"]

local action = GetAction(button)

if (action == "spell or item") then

  print("/use [@mouseover]%s", spell/item name)

end

I'm still reading into lua syntax, and trying to catch up on wowpedia.fandom.com/wiki/ for the API docs.

There's a couple issues with your code but before I get into those I'm going to jump to the end and say that even if you properly got what's on that Bartender4 button you can't call protected actions like that.

Can't simply run a /use or /cast as a script from addons.

Seems reasonable, I can setup a secure action for this later. I'm having more trouble just getting the information I need first unfortunately. I played with the following snippit in WowLua, and it actually works as intended: I get the spell name from the Bartender4 button. From addon:Initialization though the button appears to be nil, even after marking Bartender4 as a dependency :(

Code:

function ParseSpellName(spellId)

  local spellName, spellSubName, _ = GetSpellInfo(spellId);

  if spellSubName then

      return string.format("%s(%s)", spellName, spellSubName)

  else

      return spellName

  end

end





local button = _G["BT4Button73"]

local slot = button:GetAttribute('action');

local actionType, actionId, _ = GetActionInfo(slot);

if (actionType == 'spell') then

  local command = string.format("/use [@mouseover]%s", ParseSpellName(actionId))

  print(command);

end

You're addon is probably running the code before Bartender has initialised the bars. This usually happens at a specific event that fires during the game loading sequence.

It's also why it works when you're already in the game tesing in WowLua.

Try something like:

Lua Code:

function ParseSpellName(spellId)
   local spellName, spellSubName, _ = GetSpellInfo(spellId);
   if spellSubName then
      return string.format("%s(%s)", spellName, spellSubName)
   else
      return spellName
   end
end
 
 
local f = CreateFrame("Frame")
f:RegisterEvent("PLAYER_ENTERING_WORLD")
f:SetScript("OnEvent", function(self, event, ...)
    self:UnregisterAllEvents() -- PLAYER_ENTERING_WORLD will fire every time you see a loading screen so, stop that happening
    local button = BT4Button73
    local slot = button:GetAttribute('action');
    local actionType, actionId, _ = GetActionInfo(slot);
    if (actionType == 'spell') then
       local command = string.format("/use [@mouseover]%s", ParseSpellName(actionId))
       print(command);
    end
end)

That's perfect! Thank you! Everything works as expected after deferring it PLAYER_ENTERING_WORLD.
