Is there a way to prevent trigger of the completion on newline/return character (when enter is pressed)?

[abzrg]

Completion menu pops up when I press enter even in an empty line or when completion menu is not shown. I tried a bunch of combination of completion.trigger settings and only show_on_keyword = true, which totally defeats the purpose; I want to have completion menu automatically showing up except when enter is pressed (and no item is selected in the completion menu). Here's my config:

    opts = {
      appearance = {
        use_nvim_cmp_as_default = true,
        nerd_font_variant = 'mono'
      },

      snippets = {
        expand = function(snippet) require('luasnip').lsp_expand(snippet) end,
        active = function(filter)
          if filter and filter.direction then
            return require('luasnip').jumpable(filter.direction)
          end
          return require('luasnip').in_snippet()
        end,
        jump = function(direction) require('luasnip').jump(direction) end,
      },

      completion = {
        -- 'foo_|_bar' will match 'foo_' for 'prefix' and 'foo__bar' for 'full'
        keyword = { range = 'full', },

        -- Insert completion item on selection, don't select by default
        list = { selection = 'auto_insert' },

        -- Show documentation when selecting a completion item
        documentation = {
          auto_show = true,
          auto_show_delay_ms = 0,
          window = {
            border = "rounded",
          }
        },

        -- Display a preview of the selected item on the current line
        ghost_text = { enabled = false },

        menu = {
          border = "rounded",
          -- winhighlight = "Normal:Normal",
          draw = {
            columns = { { 'kind_icon' }, { 'label' } },
          }
        },

        trigger = {
          show_on_keyword = true,
          show_on_trigger_character = true,
          show_on_x_blocked_trigger_characters = { "'", '"', '(', '\n', '\r' },
        },
      },

      sources = {
        default = { 'lsp', 'path', 'luasnip', 'buffer' },

        -- Disable cmdline completions
        cmdline = {},
      },

      signature = { enabled = true },

      keymap = {
        preset = "enter",
        ["<Tab>"] = { "select_next", "snippet_forward", "fallback" },
        ["<S-Tab>"] = { "select_prev", "snippet_backward", "fallback" },
        -- ['<ESC>'] = { 'hide', 'fallback' },
      }
    },

What's your LSP?

[abzrg]

Thank you for your reply. It’s not necessarily related to an LSP. It happens in all files, even in unnamed new buffers. The candidates include snippets, buffer completion candidates for all file types, and additionally LSP candidates (e.g., clangd).

setting sources.min_keyword_length to not 0 solves it but then completions don't show on trigger character

I had this issue using blink.cmp with tpope/vim-eunuch, removing this plugin fixed for me.
Spotted that using :imap <cr> command.

[abzrg]

Thank you @Hashino and @gbprod for your help. @gbprod, In my case it was the tpope/vim-endwise. It definitely does something with <cr> :).

I have this same question. When I run :imap <cr> I get @<Plug>delimitMateCR, but in my case I want to continue using DelimitMate.
