What's the best way to expose the mode keymaps table to my consumers? about nvim-libmodal HOT 4 CLOSED

--- Checks if `fn` is a callback, or a "mode callback" (meaning it uses `self`)
--- @param fn function
--- @return boolean
local function is_mode_callback(fn)
	local info = debug.getinfo(fn, 'Su')
	return
		info.nparams == 1 -- takes one parameter
		and info.what == 'Lua' -- is a lua function
		and not info.source:find '^@vim' -- is not a builtin
end

-- Template from `:h nvim_create_autocmd`
vim.api.nvim_create_autocmd({"BufEnter", "BufWinEnter"}, {
  pattern = {"*.c", "*.h"},
  callback = vim.cmd.undo, -- ← this also doesn't work
})

function libmodal.mode.fn(f, ...)

	return function()

local fn = libmodal.mode.fn

    u = fn(vim.cmd.undo), 
    e = fn(vim.cmd.edit, 'foo'), -- you can also pass args
