hey, i'm struggling to understand how to incorporate this into my config. I'm trying to make it so that on confirm in a file picker it opens in a new tab:

map("n", "<leader>sf", function()
	Snacks.picker.files({
		confirm = function(picker, item)
			picker:action("tab")
		end,
	})
end, "Find Files")

this doesn't work, but

map("n", "<leader>Wn", function()
	Snacks.picker.projects({
		confirm = function(picker, item)
			vim.cmd({ "WorkspacesAddDir", item.text })
			picker:action("load_session")
		end,
	})
end, "New workspace")

This does work. Sorry if this is a silly question - I'm very new to lua :)

It’s not super straightforward. Action tab is basically just a shortcut for { action = 'confirm', cmd = 'cmd' }, so it’s essentially a confirm action. If you try to run a confirm action inside the confirm function, you’ll end up in a recursive loop that eventually throws an error. You can fix it like this:

Snacks.picker.files {
  actions = {
    tab = { action = 'jump', cmd = 'tab' },
  },
  confirm = function(picker, item, action)
    -- ---@cast action snacks.picker.jump.Action
    -- action.cmd = 'tab'
    -- Snacks.picker.actions.jump(picker, item, action)
    picker:action 'tab'
  end,
}
