Is it possible to setup a trigger to be a hydra- / loop-mapping?

[hbiel]

Hey everyone,

first of all, thanks for the big v3 update! It looks pretty impressive.

The following update enabling hydra-like mappings is what got me really interested in looking at my configuration again.

From what I got from the docs it's currently not possible to setup a trigger to be a hydra / looping mapping.

For example in mini.clue it's possible to map to be a recursive mapping. Each time a mapping is executed the trigger-mapping will be removed and the original mapping would be executed. Afterwards the trigger would be mapped and called again create a hydra-like use case.

Would that be possible for which-key triggers too?
Or is there something I just have missed to get this working without creating an recursion?

Thanks!

I am facing same problem, to elaborate with example:

wk.add({
	{ "<leader>x",  function() require('which-key').show({ keys = "<leader>g", loop = true }) end },
})

The above works as expected, if I press <leader>x it opens which-key window for <leader>g and stays open as I execute folowing keys. But I want it so when I press <leader>g it stays open for <leader>g, I tried the following:

wk.add({
	{ "<leader>g",  function() require('which-key').show({ keys = "<leader>g", loop = true }) end },
})

but it endlessly recurses and doesn't work. Is there something simple I am missing?

Or even simpler, in the README.md hydra example it shows the following:

-- Show hydra mode for changing windows
require("which-key").show({
  keys = "<c-w>",
  loop = true, -- this will keep the popup open until you hit <esc>
})

How would this be configured to run when <c-w> is pressed without endless recursion?

In LazyVim I have that mapped at <leader>w<space>

Hmm, I am getting error when holding down key (e.g., >) or inputting commands continuously with window mode active for extended period:

Error detected while processing NodeChanged Autocommands for "*":
Recursion deteced.
Are you manually loading which-key in a keymap?
Use `opts.triggers` instead.
Please check the docs.

Config:

local wk = require("which-key")
wk.add({
	{
		"<leader>w",
		function()
			wk.show({ keys = "<C-w>", loop = true })
		end,
	}
})

Same result with keymap:

local wk = require("which-key")
vim.keymap.set("n", "<leader>w",
	function()
		wk.show({ keys = "<C-w>", loop = true })
	end
)

Error occurs by just pressing <leader>w followed by holding down > (with vertical split open).
