Completion is auto selected when omni source is used

[wangl-cc]

Sorry about my bad description. More about this issue, please have a look at the screen recording. When I type a character, then a completion is selected immediately, and also there are two popup.

Minimal init.lua to Reproduce this issue:

require("packer").startup({
  {
    "wbthomason/packer.nvim",
    "hrsh7th/nvim-cmp",
    "hrsh7th/cmp-nvim-lsp",
    "hrsh7th/cmp-omni",
    "neovim/nvim-lspconfig",
  },
})

local cmp = require("cmp")
local cmp_lsp = require("cmp_nvim_lsp")
local lspconfig = require("lspconfig")
lspconfig.sumneko_lua.setup {
  cmd = { "lua-language-server" },
  settings = {
    Lua = {
      telemetry = { enable = false },
    },
  },
  capabilities = cmp_lsp.default_capabilities(),
}
cmp.setup {
  sources = cmp.config.sources({
    { name = "nvim_lsp" },
  }, {
    { name = "omni" },
  })
}

I have the issue

Same issue here, pretty annoying.

It seems I also have the same issue (and it's very annoying).

I only installed this since vimtex recommended it to allow its snippets to be visible here, but clearly, I need to look for another solution (or spend some time debugging this).

It's conflict with nvim_lsp, temporary solution.

local on_attach = function(client, bufnr)
  -- https://github.com/neovim/neovim/pull/19677
  -- https://github.com/hrsh7th/cmp-omni/commit/01f0f66e7dc227606bb8d8ffad688b9c393a052c
  vim.api.nvim_buf_set_option(bufnr, "omnifunc", "any non-empty character")
end

@bstaint It happens in python's omnifunc and I don't have lsp configured for python

@hrsh7th Any idea what is causing this issue (and if it indeed due to nvim_lsp conflicts whether some note should be made about this in the README itself?)

I believe you worked with @lervag over at the vimtex when they were implementing support for nvim-cmp via omni? (I see some commits on this repo were made due to issues discussed over at vimtex). Is this a new issue, or did it happen before?

[cnrrobertson]

I think the autoselection can be avoided with the vim setting vim.opt.completeopt:append('noselect') but the multiple popups are still unresolved

@bstaint Since this is already open for a while, what have you done with on_attach?
