This is what I use for url copy

local DefaultSetItemRef = SetItemRef
 
--we replace the default setitemref and use it to parse links for alt invite and url copy
function SetItemRef(link, ...)
  local type, value = link:match("(%a+):(.+)")
  if IsAltKeyDown() and type == "player" then
    InviteUnit(value:match("([^:]+)"))
  elseif (type == "url") then
    local eb = LAST_ACTIVE_CHAT_EDIT_BOX or ChatFrame1EditBox
    if not eb then return end
    eb:SetText(value)
    eb:SetFocus()
    eb:HighlightText()
    if not eb:IsShown() then eb:Show() end
  else
    return DefaultSetItemRef(link, ...)
  end
end
 
--AddMessage
local function AddMessage(self, text, ...)
  --channel replace (Trade and such)
  text = text:gsub('|h%[(%d+)%. .-%]|h', '|h%1.|h')
  --url search
  text = text:gsub('([wWhH][wWtT][wWtT][%.pP]%S+[^%p%s])', '|cffffffff|Hurl:%1|h[%1]|h|r')
  return self.DefaultAddMessage(self, text, ...)
end
 
--skin chat
for i = 1, NUM_CHAT_WINDOWS do
  local chatframe = _G["ChatFrame"..i]
  --adjust channel display
  if (i ~= 2) then
    chatframe.DefaultAddMessage = chatframe.AddMessage
    chatframe.AddMessage = AddMessage
  end
end
