Neovim version (nvim -v)

Operating system/version

Linux, Ubuntu

Describe the bug

Using the "cmp" backend for the popupmenu only works the first time, in subsequent attempts it simply does not show up.

  {
    "folke/noice.nvim",
    opts = {
      cmdline = {
        view = "cmdline",
        enabled = true,
      },
      messages = {
        enabled = true,
      },
      
      popupmenu = {
        enabled = true,
        backend = "cmp"
      }
    },

I am also using LazyVim (somewhat heavily modified), but I was able to reproduce - see bellow

Steps To Reproduce

1. Type a command and press TAB
2. It should work
3. Press ESC to exit (or choose a command)
4. Repeat, type a command, this time TAB does nothing.

Expected Behavior

The completion menu opens again, just like it does with the nui backend

Repro

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

require("lazy.minit").repro({
  spec = {
    { "hrsh7th/nvim-cmp", opts = {} },
    { "folke/noice.nvim", opts = {

      cmdline = {
        view = "cmdline",
        enabled = true,
      },
      messages = {
        enabled = true,
      },

      popupmenu = {
        enabled = true,

        backend = "cmp" 
       
      }
    } 
  },
  },
})

+1 to this as well

Also experiencing this on windows

same For temporary solution, I modified keymap.listen function in ~/.local/share/nvim/lazy/nvim-cmp/lua/cmp/utils/keymap.lua as follows:

---Register keypress handler.
keymap.listen = function(mode, lhs, callback)
  if mode == 'c' and lhs == '<Tab>' then
    return
  end
  -- Original implementation continues
end

I hope that helps

Still relevant - the behavior has changed slightly, but the "cmp" backend is still not working. I get:

Still relevant - the behavior has changed slightly, but the "cmp" backend is still not working. I get:

I guess your error is because of noice using blink.cmp instead of nvim.cmp as its new backend, and you are still using a config like backend=cmp. Instead, you can simply use this config to have a traditional cmdline view:

{
    "folke/noice.nvim",
    opts = {
      presets = {
        command_palette = false,
      },
      cmdline = {
        view = "cmdline",
      },
    },
  }
}

@Welkin-Y Actually with a quick test, it looks to me like the issue is still there:

The following config works, that is not new:

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

require("lazy.minit").repro({
  spec = {
    { "hrsh7th/nvim-cmp", opts = {} },
    {
      "folke/noice.nvim",
      opts = {
        presets = {
          command_palette = false,
        },
        cmdline = {
          view = "cmdline",  
        },
      }
    },
  },
})

Expected behavior

The behavior I expect is a "default-style" completion popup next to the cursor:

Neither with cmp or blink (which currently appears not supported). So at least backend = "cmp" should be removed from the docs if support is not planned.

@druskus20 Thanks for sharing. I just tested with the latest noice and lazyvim version and it worked pretty well.
For the latest version, you can also omit { "hrsh7th/nvim-cmp", opts = {} },, since nvim-cmp has been replaced.
