A better way to define keymaps using lazy.nvim

[KorayAydemir]

I'm trying to avoid this because its much more verbose than it should be:

return {
	"ThePrimeagen/harpoon",
	branch = "harpoon2",
	dependencies = { "nvim-lua/plenary.nvim" },
	opts = opts,
 
    keys = {
        {
            "<leader>a",
            function()
                require("harpoon"):list():add()
            end,
        },
        {
            "<C-e>",
            function()
                require("harpoon").ui:toggle_quick_menu(require("harpoon.list"), toggle_opts)
            end,
        },
        {
            "<leader>hw",
            function()
                require("harpoon"):list():select(1)
            end,
        },
   ...

I tried this:

local function keys()
    local harpoon = require("harpoon")
    return {
		{
			"<leader>a",
		         function()
				harpoon:list():add()
			end,
		},
		{
			"<C-e>",
			function()
				harpoon.ui:toggle_quick_menu(harpoon:list(), toggle_opts)
			end,
		},
}

return {
	"ThePrimeagen/harpoon",
	branch = "harpoon2",
	dependencies = { "nvim-lua/plenary.nvim" },
	opts = opts,
	keys = keys,
}

did not work. loads harpoon on startup. i dont know if its a lazy.nvim problem or a lua problem.

local function config()
    local harpoon = require("harpoon")

    -- REQUIRED
    harpoon:setup()
    -- REQUIRED

    vim.keymap.set("n", "<leader>a", function() harpoon:list():add() end)
    vim.keymap.set("n", "<C-e>", function() harpoon.ui:toggle_quick_menu(harpoon:list()) end)

    vim.keymap.set("n", "<leader>hw", function() harpoon:list():select(1) end)
end


return {
	"ThePrimeagen/harpoon",
	branch = "harpoon2",
	dependencies = { "nvim-lua/plenary.nvim" },
    config = config,
	keys = {
        "<leader>a",
        "<C-e>",
        "<leader>hw"
    },
}

with this method i'm mentioning each key twice. Once in the config function and once in the keys property.

So, why the verbosity ? There has to be a sane way to do lazy loading on key presses. Please show me what i'm missing

In the one you tried that didn't work your are missing the end keyword for the keys function. Try this:

local function keys()
    local harpoon = require("harpoon")
    return {
		{
			"<leader>a",
		         function()
				harpoon:list():add()
			end,
		},
		{
			"<C-e>",
			function()
				harpoon.ui:toggle_quick_menu(harpoon:list(), toggle_opts)
			end,
		},
}
end

return {
	"ThePrimeagen/harpoon",
	branch = "harpoon2",
	dependencies = { "nvim-lua/plenary.nvim" },
	opts = opts,
	keys = keys,
}

It's just example code, that won't work it will not lazy load telescope but load it at startup. It makes sense since lazy has to run the function to know the keys. I think I'll use the last method i showed. There's probably no way to make the second one work.
