how to use tab for both select_next snippet_forward based on condition.

[AlixShahid]

in simple term what would be the blink.cmp version of this nvim-cmp

	local cmp = require("cmp")
	local luasnip = require("luasnip")
	local neotab = require("neotab")

			["<Tab>"] = cmp.mapping(function(fallback)
				if cmp.visible() then
					cmp.select_next_item()
				elseif luasnip.expand_or_jumpable() then
					luasnip.expand_or_jump()
					-- this will auto complete if our cursor in next to a word and we press tab
					-- elseif has_words_before() then
					--     cmp.complete()
				else
					neotab.tabout()
					-- fallback()
				end
			end, { "i", "s" }),

			["<S-Tab>"] = cmp.mapping(function(fallback)
				if cmp.visible() then
					cmp.select_prev_item()
				elseif luasnip.jumpable(-1) then
					luasnip.jump(-1)
				else
					fallback()
				end
			end, { "i", "s" }),

keymap = {
  preset = "none",
  ["<Tab>"] = { "select_next", "snippet_forward", "fallback", },
  ["<S-Tab>"] = { "select_prev", "snippet_backward", "fallback", },

  ["<Enter>"] = { "accept", "fallback", },

  ["<C- >"] = { "show", "hide", },

  ["<C-d>"] = { "show_documentation", "hide_documentation", },
},

well, two problem.

1. auto completion will show in snippet and if you disable it with show_in_snippet = false, there will be no auto completion in that line
2. lua snip has disabling features and its don't works

   luasnip.config.set_config({
   	history = false, -- If true, Snippets that were exited can still be jumped back into.
   })

I have a function bound to tab which does this:

local handle_tab = function(cmp)
	-- if a snippet is running and there is no ghost text visible, snippet next
	local snippet_visible = cmp.snippet_active()
	local ghost_text_visible = cmp.is_ghost_text_visible()
	if snippet_visible and ghost_text_visible == false then
		return cmp.snippet_forward()
	end

	-- if there is ghost text but the menu is closed, open it with the ghost
	-- text's entry preselected
	local is_open = cmp.is_menu_visible()
	if is_open == false and ghost_text_visible then
		return cmp.show({
			initial_selected_item_idx = 1,
		})
	end

	if is_open then
		-- assuming the menu is open, if no option has been explicitly selected,
		-- select the first one
		local is_explicitly_selected = require("blink.cmp.completion.list").is_explicitly_selected
		if is_explicitly_selected == false then
			vim.schedule(function()
				return require("blink.cmp.completion.list").select(1)
			end)
			return true
		else
			-- finally, assuming the menu is open and an entry has been explicitly selected,
			-- select the next entry
			return cmp.select_next()
		end
	end
end
