feat(keys): `desc` in <nop> keymaps can now become prefix label

[pk-kampanart]

• User can now use keymaps with to set desc as label to prefix key

• Fix some typo

Example:

...
map("n", "<leader>h", "<Nop>", {desc = "Help Prefix"})
map("n", "<leader>p", "<Nop>", {desc = "Projects Prefix"})
map("n", "<leader>f", "<Nop>", {desc = "File Prefix"})
map("n", "<leader>b", "<Nop>", {desc = "Buffer Prefix"})
map("n", "<leader>c", "<Nop>", {desc = "Coding Prefix"})
map("n", "<leader>g", "<Nop>", {desc = "Git Prefix"})
map("n", "<leader>d", "<Nop>", {desc = "Diagnostic Prefix"})
map("n", "<leader>t", "<Nop>", {desc = "Toggle & Setting Prefix"})
...

This is actually really cool. Was just looking to implement something similar :)

fyi: It also works with an empty mapping like

map("n", "<leader>h", "", {desc = "Help Prefix"})

Thanks!

Trying to set up a prefix like this (with updated which-key (c1958e2) and lazy.nvim (0c1ec52)). Using the keys table in lazy.nvim config:

    {"<leader>t", "<nop>", mode = "n", desc = "+terminal" },
    {"<leader>tf", "<cmd>ToggleTerm direction=float<cr>", mode = "n", desc = "Toggleterm float"},

Which-key doesn't toggle for this key mapping (if it's typed fast enough), which is a drawback. I would wish for a UX where <leader>t will open which-key and wait for the real kemap (<leader>tf for toggleterm float etc.)

[folke]

@bluss can you update both which-key and lazy?

[bluss]

updated both. Fwiw, the behaviour is still the same (before and after lazy load too); typing <leader>t quick enough is just a nop and doesn't open which-key. Don't know if that's expected. Neovim v0.10.0

[folke]

which-key indeed has to have run at least once, otherwise your nop keymap would be executed. You can still use register like before. That still works.

[bluss]

Got it, thank you!

[folke]

There was indeed something wrong there and should now be fixed!

Thank you @folke. It works like I would prefer now (which-key 0099511, lazy eb49574). This case still is a minor fail: In that configuration above, if <leader>tf is pressed fast enough (no which-key trigger) then any <leader>t after that does not trigger which-key to open.
