question: using replace.desc to format non-group key descriptions?

[lloyd-pinrun]

As the title implies, I'm curious if there's a way to explicitly format the desc of a keymap for non-groups by way of the wk.Opts field replace.desc?

For example doing something like the following, all descriptions get "replaced"/formatted including keys only set as groups:

{
  "folke/which-key.nvim",
  opts = {
    replace = {
      desc = function(description) return "test: " .. desc end
    }
  }
}

It looks like require("which-key.view").replace pass through anything else to any provided functions other than the value of the key being replaced, e.g. desc or key (according to the docs), so I assume there'd be nothing for me to use to determine if the desc belongs to a group or an non-group mapping. I guess you could potentially check if the value I'm formatting is not an existing group 🤔, e.g.:

local spec = {
  { "<leader>f", group = "foo" },
  { "<leader>fb", "<cmd>Bar<cr>", desc = "bar" },
}

local groups = {}
for _, mapping in ipairs(spec) do
  if mapping.group then table.insert(groups, mapping.group) end
end

local function is_group(desc)
  for _, group in ipairs(groups) do
    if group == desc then return true end
  end
  
  return false
end

opts = {
  replace = {
    desc = function(desc)
      if is_group(desc) do return "group: " .. desc end

      return "non-group: " .. desc
    end
  }
}

I'm gonna try this rq, but tbh this is probably the answer to my question 😅

Also what I thought would work didn't... realized in retrospect it only affects my custom defined spec groups and not any predefined by LazyVim for example, so basically groups I had defined in my spec I was able to delineate in this way, but not any predefined groups.
