How do I stop the super-tab preset keymap from triggering when indenting multiple times?

[a-torgovitsky]

Suppose I want to indent a line by using two tabs in insert mode at the first character on the line.
With the super-tab keymapping, the second tab will be completed into the first completion suggestion.
How do I change this behavior?

I saw this thread: #277

But I am already using the super-tab preset. The first tab does successfully indent. But after that first tab the completion window comes up and the second tab triggers a completion.

This sounds like a bug since we block tab from triggering the menu specifically for this case. Could you provide a repro.lua for this? (check repo root for example)

Here's my repro.lua:

-- Run with `nvim -u repro.lua`

vim.env.LAZY_STDPATH = ".repro"
load(vim.fn.system("curl -s https://raw.githubusercontent.com/folke/lazy.nvim/main/bootstrap.lua"))()

---@diagnostic disable-next-line: missing-fields
require("lazy.minit").repro({
	spec = {
		{
			"saghen/blink.cmp",
			-- please test on `main` if possible
			-- otherwise, remove this line and set `version = '*'`
			build = "cargo build --release",
			opts = {
				keymap = { preset = "super-tab" },
			},
		},
		{
			"neovim/nvim-lspconfig",
			opts = {
				servers = {
					lua_ls = {},
				},
				completion = {
					-- 2025-02-01: Too annoying
					ghost_text = {
						enabled = false,
					},
					-- 2024-12-15: Makes the completion menu look nicer
					-- https://github.com/LazyVim/LazyVim/discussions/5056
					menu = {
						border = "rounded",
						winhighlight = "Normal:BlinkCmpDoc,FloatBorder:BlinkCmpDocBorder,CursorLine:BlinkCmpDocCursorLine,Search:None",
					},
					documentation = {
						window = {
							border = "rounded",
						},
					},
					-- 2025-02-01: Breaks config...I think because signature support is opt-in
					-- signature = {
					--   window = {
					--     border = "rounded",
					--   },
					-- },
				},
			},
			config = function(_, opts)
				local lspconfig = require("lspconfig")
				for server, config in pairs(opts.servers) do
					-- passing config.capabilities to blink.cmp merges with the capabilities in your
					-- `opts[server].capabilities, if you've defined it
					config.capabilities = require("blink.cmp").get_lsp_capabilities()
					lspconfig[server].setup(config)
				end
			end,
		},
	},
})

Here's my test.md file:

over
asdjlasdkljasd

I run nvim -u repro.lua test.md
Then I go to the asd... line, enter insert mode before a, and hit <tab>.
An indentation is inserted, then a completion comes up suggesting over.
If I hit tab again, the completion is accepted instead of another indentation being inserted.

My expected behavior is that a completion should not be raised after the first tab, so that the second tab indents again.

Also running into this issue. Setting opts.completion.trigger.show_on_blocked_trigger_characters = { " ", "\n", "\t" } explicitly does not work either.

For me, it seems the issue only occurs when inserting while the cursor is over some non-space character.

For example:

asdf

1. starting over a (first column) and pressing i, then tab will cause the completions menu to appear.
2. Starting anywhere else on the line and pressing I to insert at the beginning of the line will not cause tab to prompt the completions menu.

I dug through the code a bit and added some debug statements. It looks like the first conditional in on_cursor_moved is being triggered in case 1 but not case 2:

-- ./completion/trigger/init.lua
  if trigger.context ~= nil and trigger.context:within_query_bounds(cursor) then
    trigger.show({ trigger_kind = 'keyword' })

I haven't had time to look through the trigger code, but hopefully that's a start
