mapping just a name key doesn't seem to work

[jacobrreed]

whickey config (redacted unimportant info)

    return {
      plugins = { spelling = true },
      defaults = {
        mode = { "n", "v" },
        ["<leader>"] = {
          L = { name = "LSP" },

but for some reason L is showing just +prefix

I've also tried this inside my lspconfig

 local on_attach = function(_, bufnr)
      opts.buffer = bufnr

      wk.register({
        L = { name = "LSP" },
      }, { prefix = "<leader>" })

also doesn't work

I was having the same problem until I realized it actually is setting the name, it's just getting overridden with the default when the group name isn't specified in subsequent calls to wk.register. This is true even when setting a key binding associated with a buffer when the group name is set globally (without being associated with a buffer).

You might just need to name your group after the rest of your key bindings, and assign the binding to the buffer if you're going to do it in on_attach:

local on_attach = function(_, bufnr)
  -- wk.register({....}) -- Create other key bindings first.
  -- Then register the group name
  wk.register({
    L = { name = "LSP" },
  }, {
    prefix = "<leader>",
    buffer = bufnr,
  })
  -- Don't register any more key bindings in the `L` group after that unless you also name the group again.

It should also work if you combine the bindings into one call to wk.register, as long as it's the last call to wk.register that affects anything in the associated groups.
